A tool positioning system for use in a medical procedure is provided which includes a medical tool configured to be navigated to a target tool location within a portion of an organ of a patient. The medical tool includes a sheath having a tube defined by a sheath wall, the sheath extending a length in a proximal-distal direction and an inflatable balloon coupled to the sheath and configured to move along the length of the sheath in the proximal-distal direction. When the inflatable balloon is inflated at a target balloon location along the length of the sheath, the inflated balloon is fixed at the target balloon location. The tool positioning system also includes memory configured to store location of the tool in a three dimensional (3D) space and at least one processor configured to generate mapping information for displaying locations of the tool in the 3D space.

An image scanning, displaying and lighting system for eliminating color differences is revealed. The system includes an image scanner, a display screen with a second emission spectrum and a lighting device with a third emission spectrum. The image scanner consists of an optoelectronic image capturing and forming system, a plurality of first light sources disposed around the optoelectronic image capturing and forming system and a control module. The first light sources have a first emission spectrum which is a white light composed of a plurality of wavebands with different peak wavelengths. The control module controls the optoelectronic image capturing and forming system to take monochrome images in different colors in time sequence. The second emission spectrum has the same characteristics as the first emission spectrum while the third emission spectrum has the same characteristics as the second emission spectrum.

A holding frame for an imaging unit arranged at a distal end of an endoscope includes a cylindrical three-dimensional molded interconnect device; a housing configured to house the imaging unit, the housing being formed of a notch; at least one cut face formed on the side face of the holding frame and obtained by cutting a support portion which is a gate portion into which a resin is injected when the holding frame is resin-molded; a connection terminal formed on a bottom face of the housing portion and configured to be connected to the imaging unit; a cable connection electrode arranged on a face where a proximal end side of the holding frame is notched; and a wiring pattern formed on a surface area of the holding frame excluding the cut face and configured to electrically connect the connection terminal and the cable connection electrode.

A medical instrument port is described for use with a surgical mask or other protective face covering. The medical instrument port provides a sealed pathway through which a medical instrument can be passed without exposing the clinician to aerosolized droplets expelled from the patient's respiratory system when the medical instrument is introduced into the patient's nasal and/or oral passages.

Embodiments generally relate to propulsion devices, systems, or components thereof, for progressing instruments along passages, as well as associated methods of manufacture. For example, the instruments may include tools, sensors, probes and/or monitoring equipment for medical use (such as endoscopy) or industrial use (such as mining). The described embodiments may also be suitable for applications in other fields to progress an instrument along a passage. Some embodiments relate to an endoscope comprising or configured to receive a propulsion tube configured to assist in progressing the endoscope along a passage.

A device for attaching an optical element, such as an otoscope, to a smart phone for diagnosing and/or identifying problems of an outer ear, a middle ear, and/or an ear canal of a patient. The device may comprise a main body. The main body may comprise an aperture and a first engagement member configured to engage with a second engagement structure that belongs to the optical element. A first surface may be connected to the main body and configured may be to contact a first smart phone surface. A piston may be provided that may comprises a second surface that may be parallel to the first surface and may be configured to contact a second smart phone surface. A threaded knob may be provided and may be connected to the piston through the aperture.

A connector ring includes a retention portion; an intermediate portion; and a plug hood made of a flexible material, the intermediate portion connecting the retention portion to the plug hood, wherein the retention portion and the plug hood are larger in cross-section than the intermediate portion in at least one radial extent. The connector ring can be removably attached to a video processing apparatus through an aperture in a wall of the video processing apparatus.

Example embodiments relate to surgical systems. The surgical system includes a port assembly and instrument arm assembly. The port assembly includes a central access channel, anchoring portions, and anchor channels. The instrument arm assembly includes a shoulder section, first arm section, shoulder joint portion, elbow joint portion, second arm section, wrist section, end instrument, and instrument arm anchor segment. The instrument arm anchor segment includes an anchor body and instrument arm anchor portion. The anchor body is secured to the shoulder section. The anchor body is inserted through one of the anchor channels. The instrument arm anchor portion secures to one of the anchoring portions when the anchor body is housed in one of the anchor channels. The central access channel remains as an open access channel through the port assembly when the instrument arm anchor portion is anchored to one of the anchoring portions.

An in-body image capturing device (camera unit) with high reliability is suggested. A camera unit (11) includes an image capturing unit that includes a lens (26) and a first illumination unit (27a) and is capable of being introduced into a body. The first illumination unit (27a) and the image capturing unit are housed in a casing (22) that is integrally molded with an integral light-transmitting body (22x) and an integral light shielding body (22y).

An assembly for driving linear movement and roll movement of an elongate surgical tool, comprising: an elongate shaft comprising a central lumen extending along the shaft long axis; the elongate shaft comprising a plurality of apertures extending across walls of the elongate shaft and into the central lumen; a set of wheels positioned opposing each other and aligned on two sides of the central lumen, the set of wheels at least partially extending through the apertures beyond the walls of the elongate shaft and into the central lumen to contact an elongate surgical tool received therein; the set of wheels being coupled to the elongate shaft and configured to rotate with the elongate shaft as a single unit when the elongate shaft is rotated about the shaft long axis.
