DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

[0076] Referring now to FIGS. 1-3, schematic views of an exemplary embodiment of a device 100 is shown during use cleaning an elongated instrument 200. In the embodiment shown, device 100 is configured to clean a surface 210 of elongated instrument 200 held within a cavity (e.g. in a bodily cavity vivo or in an earthly cavity in-ground). In certain embodiments surface 210 may be a lens and elongated instrument 200 may be a laparoscope. In the illustrated embodiment, elongated instrument 200 comprises a proximal end 211 and distal end 212. In this embodiment, device 100 comprises a longitudinal wire member 110 comprising a proximal end 111 and a distal end 112. Device 100 also comprises a rotatable transverse member coupled to distal end 112 of longitudinal wire member 111). As used herein, distal end 112 of longitudinal wire member 110 comprises a region of longitudinal member 110 that is distal from the absolute end of longitudinal wire member 111). Accordingly, a portion (e.g. 5 or 10 percent) of longitudinal wire member 110 may extend beyond the coupling point, of rotatable transverse member 120 and longitudinal wire member 110 (e.g. may extend away from distal end 112). In certain embodiments, longitudinal wire member 110 and rotatable transverse member 120 may be formed from a unitary component, while in other embodiments, longitudinal wire member 110 and rotatable transverse member 120 may be separate components. In exemplary embodiments, longitudinal wire member 110 is configured as a long, thin, member that allows rotation of distal end 112 upon rotation of proximal end 111. Exemplary embodiments of longitudinal wire member 110 comprise metallic and non-metallic materials, including for example composite, plastic or other polymer materials.

[0077] In the embodiment shown, device 100 comprises a retaining member 250 configured to retain a component of device 100 (e.g. longitudinal wire member 110 in the embodiment shown) to elongated instrument 200. In this embodiment, retaining member 250 is shown as a tubular member or sheath that is coupled to device 100 and extends around elongated instrument 200. In certain embodiments, retaining member 250 may be configured as a multi-lumen tube. It is understood that in other embodiments, retaining member 250 may include other configurations, including for example, clips, wires, etc. As explained in further detail below, retaining member 250 is configured to allow sliding or lateral movement between device 100 and elongated instrument 200 in a direction parallel to an axis 101 that extends colinearly from distal end 112. In addition, retaining member 250 is also configured to allow rotational movement of device 100 about axis 101 to facilitate cleaning matter 213 (e.g. solid or liquid) from surface 210.

[0078] The embodiment shown further comprises an indicator 121 coupled to longitudinal wire member 110 near proximal end 111. Indicator 121 can indicate the orientation of rotatable transverse member 120 such that a user can determine the position of transverse member 120 with respect to elongated instrument 210 by viewing indicator 121 while rotating device 100 about longitudinal wire member 110 and axis 101.

[0079] In the embodiment shown in FIG. 1, device 100 is shown with distal end 112 and rotatable transverse member 120 extended past surface 210 such that surface 210 is between proximal end 111 and distal end 112 of longitudinal wire member 110. The user can view indicator 121 to align rotatable transverse member 120 so that it is aligned rotationally with elongated instrument 200 (e.g. rotatable transverse member 120 is generally “above” surface 120 in the configuration shown in FIG. 1.) Device 100 and/or elongated instrument 200 can then be moved in the direction of arrow L parallel to axis 101 shown in FIG. 1 such that rotatable transverse member 120 is positioned proximal to surface 210. For example, the user can pull proximal end 111 of longitudinal wire member 110 or push elongated instrument 200 in order position rotatable transverse member 120 proximal to surface 210. In certain embodiments, rotatable transverse member 120 (e.g. the cleaning member or a wiper) can be moved between a stowed position and a use position. The stowed position and the use position are relative to a location of the imaging element of an endoscope when the endoscope is mounted on the apparatus. The use position can be a position in which rotatable transverse member 120 is adjacent to or beyond a terminal end of the endoscope. The stowed position can be a position in which rotatable transverse member 120 is retracted from the use position in a direction toward a user interface body of the apparatus.

[0080] As device 100 and/or elongated instrument 200 is moved in this direction, rotatable transverse member 120 eventually engages surface 210 as shown in FIG. 2. The engagement of rotatable transverse member 120 with surface 210 provides tactile feedback to the user through longitudinal member 110 to indicate engagement. For example, the resistance in the relative lateral/axial motion between device 100 and elongated instrument 200 is created when rotatable transverse member 120 engages surface 210. As shown in FIG. 3, the user can then rotate longitudinal wire member 110 and rotatable transverse member 120 about axis 101 in the direction of arrow R to wipe clean surface 210. Indicator 121 can be used to confirm that rotatable transverse member 120 has rotated sufficiently to clean debris from surface 210. In certain embodiments surface 210 is not flat and may comprise a raised surface around the perimeter of the distal end of elongated instrument 200. Such configurations can present challenges to efficient cleaning of surface 210 and emphasize the need for effective cleaning devices and techniques.

[0081] It is understood the views shown in FIGS. 1-3 represent schematic representations of one embodiment of the present disclosure. Other embodiments may include additional features and aspects. Referring now to FIGS. 4-13, assembled and exploded views are provided of a particular embodiment of a device 100 configured to clean an elongated instrument having an angled surface at the distal end. Components that are equivalent to previously-described components are identified with equivalent reference numbers. For the sake of brevity and to avoid repetition, equivalent components will not be discussed in detail in the description of this embodiments. An overview of the components and operating principles will be presented initially, followed by more specific discussion of particular features of device 100.

[0082] In the embodiment shown, device 100 comprises a handle 300 coupled to an actuation member 320, a guide member 330 and a coupling member 340. Actuation member 320 is coupled to longitudinal wire member 110 and can be used to manipulate longitudinal wire member 110 and rotatable transverse member 120 during use. The general operating principles of this embodiment are equivalent to those of the previously-described embodiment in FIGS. 1-3. During use, an elongated instrument (e.g. a laparoscope in certain embodiments, not shown) can be inserted through retaining member 250, and coupling member 340 can be used to couple device 100 to the elongated instrument. In a particular embodiment, coupling member 340 comprises an elastic material with an aperture 341 (see FIGS. 6 and 11) that can be placed over a light port in a laparoscope to constrain lateral and rotational movement of device 100 relative to the elongated instrument. Coupling member 340 may also comprise a tab or extension 343 to assist is manipulating coupling member 340 during the coupling process to the elongated instrument. For example, a user can grasp extension 343 and pull extension 343 initially in a direction away from aperture 341 until aperture 341 is located proximal to the portion of the elongated instrument to which it will be coupled. Extension 343 can then be pulled in a different direction (e.g. toward distal end 251 of retaining member 250) until aperture 341 has engaged and secured device 100 to the elongated instrument. Extension 343 can then be released by the user.

[0083] In certain embodiments, a cavity into which device 100 is inserted may be filled with pressurized gas (e.g. insufflation gas in the abdomen during laparoscopic surgery) to allow for a maintenance of cavity pressure or gas concentration. In particular embodiments, device 100 may comprise a seal that can be located at proximal and/or distal end of the device that creates a seal around the elongated instrument and/or retaining member 250 and prevents leaking of gas from the cavity. This can be done through an elastic component that compresses around scope, passively, but still allows for scope to push through longitudinal member, or it could be done through a compliant foam or rubber port, that can be moved aside as the elongated instrument pushes past the compliant part, and the compliant part forms a seal around the elongated instrument.

[0084] In the embodiment shown, coupling member 340 further comprises a second aperture 342 which is aligned with a central aperture 255 of retaining member 250 when device 100 is assembled. A seal 344 extends around aperture 342 and restricts the flow of gas through aperture 255 of coupling member 250. Seal 344 can therefore restrict insufflation gas from escaping the cavity into which device 100 is inserted during use. While seal 344 is shown in this embodiment as a unitary component with coupling member 340, it is understood that in different embodiments seal 344 and coupling member 340 may be separate components. In exemplary embodiments, coupling member 340 and/or seal 344 may be formed from an elastic, foam, or other suitably compliant material. In addition, while aperture 342 is shown as a single aperture, other embodiments may comprise multiple partitions or “leaves” that deflect out of the way and back around the shaft of the elongated instrument as the elongated instrument pushes past aperture 342.

[0085] As shown in FIG. 9, retaining member 250 is configured as a tubular member that comprises a wall 257 extending around central aperture 255, as well as a relief 253 (e.g. a semi-circular groove or slot in the illustrated embodiment) in wall 257. Relief 253 extends along retaining member 250 and is sized and configured such that longitudinal wire member 110 is retained in relief 253 without obstructing central aperture 255. Accordingly, relief 253 aligns longitudinal wire member 110 in a straight configuration as it travels the length of retaining member 250. In addition, longitudinal wire member 110 can rotate while being retained within relief 253.

[0086] In the embodiment shown, retaining member 250 further comprises a slot 254 through wall 257 and near a proximal end 252 of retaining member 250. Slot 254 is configured to allow guide member 330 (and longitudinal wire member 110) to enter relief 253. In the illustrated embodiment, retaining member 250 further comprises a slot or notch 259 configured to engage a locating rib or tab 258 in handle 300 (shown in FIG. 7) to position or key retaining member 250 to handle 300. The embodiment of retaining member 250 shown in FIG. 9 comprises a distal end 251 that is angled (e.g. to accommodate elongated instruments with angled distal surfaces).

[0087] In the embodiment shown in FIG. 12, guide member 330 comprises an aperture 335 through which longitudinal wire member 110 extends. In addition, guide member 330 comprises a curved portion 337 configured to transition longitudinal wire member 110 from actuation member 320, through handle 300 and to retaining member 250. Guide member 330 can further distribute the bending forces exerted on longitudinal wire member 110 and reduce frictional forces as longitudinal wire member 110 is rotated and laterally translated during operation. In specific embodiments, guide member 330 may be formed from 304 or 316 stainless steel, and longitudinal wire member 110 may be formed from 316 stainless steel.

[0088] In the embodiments shown in FIGS. 10 and 13, longitudinal wire member 110 comprises a curved portion 115 near distal end 112, and rotatable transverse member 120 comprises a slot 123 configured to receive curved portion 115 of longitudinal wire member 110. In the embodiment shown, curved portion 115 is configured at an angle A with respect to distal end 112 that is equivalent to distal end 251 of retaining member 250. In exemplary embodiments, rotatable transverse member 120 is coupled to distal end 112 of longitudinal wire member 110 via a friction fit between slot 123 and curved portion 115. In certain embodiments, rotatable transverse member 120 can be removed and replaced by a user by pulling on rotatable transverse member 120 in a direction parallel to curved portion 115. In the embodiment shown, rotatable transverse member 120 comprises an angled surface 127 configured to provide improved wiping or cleaning action during use. In exemplary embodiments the geometry, contact angle, contact force, and material of construction can be optimized for rotatable transverse member 120 to provide for efficient cleaning of the elongated instrument.

[0089] In the embodiment shown in FIG. 8, actuation member 320 comprises a first aperture 322 configured to receive longitudinal wire member 110. In the embodiment shown, actuation member 320 comprises a second aperture 324 configured to receive a coupling member 326 configured to secure longitudinal wire member 110 to actuation member 320. In the embodiment shown, coupling member 326 is a threaded member, but in other embodiments coupling member 326 may have a different configuration (e.g. a pin, stake, etc.).

[0090] In certain embodiments, device 100 and an elongated instrument can be inserted through a trocar into a cavity of a patient during use. As shown in FIGS. 7 and 8, actuation member 320 comprises an indicator 121 that is aligned with rotatable transverse member 120. A user can initially manipulate actuation member 320 by rotating it such that rotatable transverse member 120 does not extend over the distal end of the elongated instrument and interfere with operation of the elongated instrument. For example, if the elongated instrument is a laparoscope, rotatable transverse member 120 will not block the view of the laparoscope when rotatable transverse member 120 is positioned 180 degrees from the position shown in FIG. 4. However, if matter accumulates on the end of the elongated instrument during use, actuation member 320 can be manipulated to remove the matter and restore the functionality of the elongated instrument.

[0091] In particular, actuation member 320 can be rotated such that rotatable transverse member 120 is aligned with retaining member 250 as shown in FIG. 4. Device 100 and/or elongated instrument 200 can then be moved such that rotatable transverse member 120 is positioned proximal to the distal end of the elongated instrument. For example, the user can pull actuation member 320 in a direction away from handle 300 (and/or push the elongated instrument further into retaining member 250) such that the distance between rotatable transverse member 120 and distal end 251 of retaining member 250 is reduced. Such movement can be continued until rotatable transverse member 120 engages the distal end of the elongated instrument located within retaining member 250.

[0092] Actuation member 320 can then be rotated such that rotatable transverse member 120 is rotated via longitudinal wire member 110. The rotation of rotatable transverse member 120 can remove matter (e.g. via a wiping, cleaning or scraping action) from a surface at the distal end of the elongated instrument. In certain embodiments, actuation member 320 is only capable of being rotated one direction (e.g. either clockwise or counter-clockwise) to prevent buildup of debris on both sides of rotatable transverse member 120, and thereby prevent re-distributing debris on the surface of the elongated instrument. In other embodiments, actuation member 320 can be operated to rotate hi-directionally to allow for user-preferred actuation.

[0093] In particular embodiments, actuation member 320 can then be moved toward handle 300 (and/or the elongated instrument can be withdrawn slightly from retaining member 250) such that rotatable transverse member 120 is moved laterally away from retaining member 250 and the elongated instrument. Actuation member 320 can also be rotated to position rotatable transverse member 120 such that rotatable transverse member 120 does not interfere with operation of the elongated instrument (e.g. rotatable transverse member 120 is not aligned with retaining member 250 and does not block the view of a laparoscope inserted in retaining member 250). Accordingly, the elongated instrument can perform its desired function without interference from rotatable transverse member 120.

[0094] In exemplary embodiments, rotatable transverse member 120 may be a soft, flexible material that can remove matter from a distal end of an elongated instrument (e.g. a lens of a laparoscope or other viewing instrument) without damaging the distal end of the instrument. For example, in specific embodiments rotatable transverse member 120 may be formed from or comprise a rubber, elastomer, foam, sponge, thermoplastic polyurethane (TPU), thermoplastic elastomers (TPE), medical-grade silicone, silk, polyester, microfiber, or napped material to engage the surface to be cleaned on the elongated instrument. In certain embodiments, materials such as thermoplastic polyurethane (TPU), thermoplastic elastomers (TPE) and medical-grade silicone can be overmolded or insert molded.

[0095] It is understood that features and aspects of the embodiment shown in FIGS. 1-3 and 4-13 can be combined with features and aspects of other embodiments shown herein and/or modified. For example, the embodiment shown in FIGS. 4-13 could be modified such that actuation member 320 provided rotational movement only and did not provide lateral translation of longitudinal wire member 110. In such embodiments, lateral movement between the distal end of the elongated instrument and rotatable transverse member could be accomplished by moving the elongated instrument laterally within retaining member 250 or moving the entire device 100 laterally with respect to the port of entry into the cavity.

[0096] In addition, certain embodiments may provide for vacuum, liquid or surfactant delivery. Such provisions could go to or from the surface of the elongated instrument, or to or from the rotatable transverse member. In certain embodiments, the rotatable transverse member could be coated in cleaning liquid, or absorb it for future distribution to scope upon contact. In certain embodiments, the surface of the elongated instrument or the rotatable transverse member could also be coated in material that prevents buildup of debris (dust, blood, oils, fats, etc.)

[0097] Particular embodiments may also provide for passive defogging of the surface of the elongated instrument that is cleaned via built in “natural” humidity collection. For example, the geometry and size of the retaining member can be selected to allow for collection of vapor on the retaining member walls when environmental conditions are favorable. When the elongated instrument is inserted through the retaining member, vapor droplets adhering to walls may contact the elongated instrument surface, thereby passively distributing the droplets onto the instrument surface. This can further create a thin film or layer of the collected liquid (which could be a warm or cold liquid) onto the instrument surface. In function, the liquid is transparent, which can maintain clear visibility through the instrument surface when the surface is a lens. In addition, the film or thin layer of liquid prevents fog buildup, as the surface does not collect additional condensation on top of the thin layer of condensation that was just collected during the insertion of the instrument into the cavity. The process may be a result of the open-nature of the tubular retaining member that allows for the movement of cool air into the warm cavity (i.e. temperature difference) to interact with the warm moist environment, which meets temperature and humidity conditions needed for vapor droplets to form on inner wall of the tubular retaining member.

[0098] Particular embodiments may also comprise an actuation mechanism for a robot in which the actuation member or members are combined with a docking station that are able to integrate with a robot. In certain embodiments, power can come via robot electrically, or can be transferred via docking station where the device itself does not take in electrical power, but docks in a manner able to accept mechanical energy. For example, the electric robot turns gears, the device docks, and gears on robot turn gears on device. Other embodiments could work with cables or other mechanisms to mechanically transfer energy, or could utilize a separate actuation station not powered by the robot that draws power elsewhere, e.g. a battery or electrical outlet.

[0099] All of the devices, systems and/or methods disclosed and claimed herein can be made and executed without undue experimentation in light of the present disclosure. While the devices, systems and methods of this invention have been described in terms of particular embodiments, it will be apparent to those of skill in the art that variations may be applied to the devices, systems and/or methods in the steps or in the sequence of steps of the method described herein without departing from the concept, spirit and scope of the invention. All such similar substitutes and modifications apparent to those skilled in the art are deemed to be within the spirit, scope and concept of the invention as defined by the appended claims.
