A surgical stabilizer arm includes a reusable base portion and a disposable arm portion. The articulating links that enable the arm to be positioned into arbitrary trajectories are included the disposable portion, thus eliminating the need to clean between the links after a surgical procedure. The disposable portion also includes a tool attachment mechanism and a cable. The reusable portion includes a retractor clamping mechanism, a top plate, a T-shaped base post, a main body, a nosepiece, a threaded drawbar, a thrust bearing assembly, and a threaded handle that can extend or retract the drawbar when rotated. The threaded drawbar may include a slot into which an end of the cable can be inserted, which allows tension to be applied to the cable when the handle is rotated to pull the drawbar into the body of the reusable portion and lock the articulating links in place.

A surgical instrument including a reusable and sterilizable hub assembly and a releasably connectable disposable blade assembly allows multiple reuse of the hub assembly in conjunction with single use disposable blade assemblies.

A medical instrument includes a first hand lever which has a manually actuated grip portion at its proximal end, a work portion for gripping, clamping or cutting an object at its distal end, and, lying between these, a bearing portion on which a bearing element engages in order to permit pivotability about a rotation axis between the first hand lever and a second hand lever, wherein the second hand lever has a grip portion at its proximal end, a work portion at its distal end, and, lying between these, a guide portion on which the bearing element engages, wherein the guide portion of the second hand lever has on one side a recess for receiving the bearing portion of the first hand lever such that two guide protrusions located distally and proximally of the recess at least partially cover the bearing portion in an operating position.

A positioning and retrieval device manipulated by carrying element coupled to an handle and driven by an actuator that allows for axial movement and rotational movement of a capturing portion on the carrying element.

Generally, a sterile adapter for use in robotic surgery may include a frame configured to be interposed between a tool driver and a surgical tool, a plate assembly coupled to the frame, and at least one rotatable coupler supported by the plate assembly and configured to communicate torque from an output drive of the tool driver to an input drive of the surgical tool.

An arrangement for the sterile handling of a non-sterile endoscope in a sterile environment comprises a sterile endoscope sheath for accommodating the endoscope and a cable via which the endoscope is connectable to a control unit, the arrangement further comprising a sterile cable sheath for accommodating at least a portion of the cable, wherein the endoscope sheath comprises a first sterile lock comprising at least one first sterile flap which in the closed state shields the endoscope arranged in the endoscope sheath in a sterile manner. The cable sheath comprises a second sterile lock having a second sterile flap which in a closed state shields the cable arranged in the cable sheath and/or a plug connector present on the arranged cable in a sterile manner. When connecting the cable or the plug connector to the endoscope, a movement of the first sterile flap from the closed state into an open state takes place and a movement of the second sterile flap from the closed state into an open state takes place so that a direct coupling of the cable to the endoscope or of the plug connector connected to the cable to a complementary plug connector of the endoscope is possible.

An optical tracking system is provided. The optical tracking system comprises an autoclavable fiducial marker assembly including an opaque housing, a light source, a window panel configured to refract light rays from the light source therethrough, and a metallized coating forming a hermetic seal at an interface of the window panel and the opaque housing. The fiducial marker assembly is configured to shield a peripheral edge of the window panel from the light rays. The system further comprises a tracking device comprising at least two optical sensors configured to detect a position of a light ray emitted by the light source. The system further comprises a processor configured to receive the position of the light rays from the optical sensors, shift the position of each light ray based on a calculated refraction deviation, and triangulate the location of the light source based on the shifted position of each light ray.

A device for loading a trocar assembly with an adapter assembly of a surgical stapling instrument and a method of confirming that the trocar assembly is properly secured to the adapter assembly are provided. The device includes a base member and an engagement arm secured to the base member. The base member defines a longitudinal passage for receiving a trocar assembly and includes a proximal end surface. The engagement arm is configured to releasably secure a trocar assembly within the base member. The engagement arm includes a proximal end surface. The proximal end surface of the base member is configured to engage a distal end surface of a trocar housing of the trocar assembly when the trocar assembly is not properly secured within the adapter assembly.

A surgical instrument includes a power pack, an outer shell housing configured to selectively encase the power pack, and an adapter assembly configured to selectively couple the outer shell housing to a loading unit. The outer shell housing includes a motor and a drive shaft coupled to and rotatable by the motor. The outer shell housing includes a drive member supported in a distal portion thereof. The drive member is configured to selectively couple to the drive shaft. The adapter assembly has a drive member supported in its proximal end. The drive member of the adapter assembly is configured to selectively couple to the drive member of the outer shell housing such that rotation of the drive shaft actuates movement of the drive member of the adapter assembly via the drive member of the outer shell housing.

An apparatus comprises an electrically power surgical instrument having a handle assembly. The apparatus also comprises a communication device positioned within the handle assembly. The communication device is operable to communicate with at least a portion of the electrically powered surgical instrument. The apparatus further comprises an external device in wireless communication with the communication device. The external device is operable to receive information from the communication device and the external device is operable to provide an output viewable to the user.
