A disposable uterine endoscope relates to the technical field of medical instruments. The disposable uterine endoscope includes a handle mechanism and an intubation mechanism. The intubation mechanism includes a rotary inner tube and a supporting outer tube. One end of the rotary inner tube is rotatably connected with the handle mechanism and the other end of the rotary inner tube is connected with a camera. The supporting outer tube is sleeved in a circumferential direction of the rotary inner tube, one end of the supporting outer tube is fixedly connected with the handle mechanism and the other end of the supporting outer tube is provided with a bent section, the bent section is provided with a continuous bent groove, and the bent groove is arranged spirally along the circumferential direction of the bent section.

A method comprises, based on a position of a medical instrument within a patient anatomy, determining, by a control system, whether an obstruction is on a surface of a lens of the medical instrument. The method further comprises, based on a determination that the obstruction is on the surface of the lens, instructing, by the control system, a valve control mechanism to open a valve to release a flow of pressurized fluid through a nozzle of the medical instrument and over the surface of the lens. The valve is configured to control provision of the pressurized fluid.

This disclosure relates generally to a container and tube set and methods for fluid delivery, and particularly an integrated container and tube set suitable for use with an endoscope to supply liquids and/or gases to the endoscope. The integrated container and tubes may include a container (e.g., water reservoir) containing a fluid and a gas, and a plurality of tubes integrally formed with the container. The integrated container may include an irrigation supply tube having a first lumen in fluid communication with the fluid, a lens wash supply tube having a second lumen in fluid communication with the fluid, a gas supply tube having a third lumen in operative communication with the gas, and an optional alternative gas supply tube having a fourth lumen in fluid communication with the gas. The lens wash supply tube and the gas supply tube may be formed as a single, multi-lumen tube.

An endoscope and lens cleaning device assembly includes a tubular body, a visualization device including a lens, and a lens cleaning device. The visualization device is supported on a distal portion of the tubular body. The lens cleaning device is supported on the distal portion of the tubular body and includes an iris mechanism having a plurality of vanes. The vanes are movable between a first position in which the vanes are positioned radially outwardly of the lens of the visualization device and a second position in which the vanes cover the lens of the visualization device. Each of the vanes has a cleaning surface that is positioned to contact the lens of the visualization device as the vanes move between the first and second positions to clean the lens of the visualization device.

A system for supplying insufflation gas for a surgical procedure includes first and second insufflation gas inlets for receiving insufflation gas from at least two insufflation gas supply tanks located in an operating room; an insufflation gas outlet for providing a flow of insufflation gas supplied via the first and second insufflation gas inlets; and a valve system configured to automatically switch from insufflation gas supply via the first insufflation gas inlet to insufflation gas supply via the second insufflation gas inlet to maintain insufflation gas flow at the insufflation gas outlet.

A cannula assembly includes a housing, an elongate shaft extending from the housing, and a lens cleaning assembly detachably coupled to a distal end portion of the elongate shaft. The elongate shaft defines a lumen therethrough. The lens cleaning assembly includes a base having an annular configuration and defines an aperture in communication with the lumen of the elongate shaft, a cover pivotably coupled to the base, and a spring biasing the cover towards the closed configuration. The cover is transitionable between a closed configuration, in which, the cover closes the aperture of the base, and an open configuration, in which, the cover is spaced apart from the aperture. The cover has a cleaning surface facing the aperture of the base in the closed configuration.

Endoscopes of this disclosure, such as colonoscopes, provide a broader field of view and allow extended access of surgical tools, and also enable efficient packing of all necessary elements in the tip section, while maintaining their functionality. Methods and systems of this disclosure include for capturing and displaying still and video images using an endoscope corresponding to a left-side looking viewing element, a front-looking viewing element, and a right-side looking viewing element of an endoscopic tip generated in a native aspect ratio.

Components for an endoscopic vessel harvesting system suitable for harvesting target vessels such as the saphenous vein or radial artery for cardiac artery bypass graft surgery. The main components of such systems include a vessel dissector and a vessel harvester, both of which work in conjunction with a separately provided endoscope. The vessel dissector is an elongated cannula having a blunt tip for separating layers of facial around vessels. The tip may be movable, and is typically transparent to permit viewing forward of the tip using the endoscope. Internal features of the tip may reduce glare back to the endoscope. Several devices improve visibility through the tip by reducing interference from tissue or fluid on the tip. The vessel harvester also has an elongated cannula for receiving the endoscope. Several tools within the harvester permit manipulation, severing, and sealing of vessels forward of the distal end. The tool for manipulating vessels may have a low-profile for increased visibility of operation, and may be coupled to the cannula with a damping mechanism to reduce the possibility of avulsion of the vessels. Various vessel cutting and sealing devices are provided that may accommodate various sizes of vessels and improve cutting and sealing efficacy.

A sheath for providing a dynamic air shield relative to a distal portion of a laparoscope disposed within the sheath includes a sheath elongate body having an inner surface and an outer surface, a plurality of lumens, and a distal portion configured to deflect air from the lumens across the surface of a laparoscope. The sheath can include a registration and alignment feature configured to align the sheath with a laparoscope. Further, the sheath can be configured to work with robotic laparoscope systems.

A minimally invasive surgical instrument including a viewing instrument and a wiper mechanism configured and adapted to clean a lens of the viewing instrument. The wiper mechanism includes a wiper that is configured and adapted to contact and translate across a surface of the lens. An actuator moves the wiper across the lens to clean the lens.
