A visualization system including multiple light sources, an image sensor configured to detect imaging data from the multiple light sources, and a control circuit is disclosed. At least one of the light sources is configured to emit a pattern of structured light. The control circuit is configured to receive the imaging data from the image sensor, generate a three-dimensional digital representation of the anatomical structure from the pattern of structured light detected by the imaging data, obtain metadata from the imaging data, overlay the metadata on the three-dimensional digital representation, receive updated imaging data from the image sensor, and generate an updated three-dimensional digital representation of the anatomical structure based on the updated imaging data. The visualization system can be communicatively coupled to a situational awareness module configured to determine a surgical scenario based on input signals from multiple surgical devices.

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.

Maximum hardness of a flexible tube section of an endoscope is set such that substantial maximum hardness at a time when an over-tube is attached is equal to or lower than maximum hardness of a flexible tube section of an endoscope. That is, the maximum hardness of the flexible tube section of the endoscope is set substantially equal to hardness obtained by subtracting hardness of the over-tube itself from the maximum hardness of the flexible tube section of the endoscope. In the endoscopes including a hardness changing function, maximum hardness of the endoscope, to which the over-tube is not attached, and maximum hardness of the endoscope, to which the over-tube is attached, are set substantially equal.

The present invention relates to a cover having a plurality of moveable, external, angled projecting elements for use with flexible medical scoping devices such as endoscopes or enteroscopes. The invention includes the cover with an over cuff and use of the disposable removable covering in methods of medical scoping procedures or examinations. The invention also includes an applicator for assisting in placing the covering about or over a medical device and a kit of parts.

This endoscopic surgical device includes: an endoscope; a treatment tool; and a mantle tube. The inside of the mantle tube is partitioned by a partition wall member provided with an endoscope guide groove and a treatment-tool guide groove, to form an endoscope insertion passage and a treatment-tool insertion passage. An endoscope fixation tool and a treatment-tool fixation tool are respectively disposed inside the endoscope guide groove and the treatment-tool guide groove. The endoscope fixation tool advances and retracts in conjunction with the endoscope insertion part inserted through the endoscope insertion passage. The treatment-tool fixation tool moves in conjunction with the treatment-tool insertion part inserted through the treatment-tool insertion passage. When a coupling ring externally fitted to the partition wall member interlocks the endoscope fixation tool with the treatment-tool fixation tool, the endoscope insertion part also moves in conjunction with the advancement and retraction of the treatment-tool insertion part.

A surgical port includes a first end, a second end opposite the first end, and a longitudinal axis extending through the first end and the second end. An outer sidewall extends between the first end and the second end. First and second channels extend through the port from the first end to the second end. A first electrically conductive portion extends from the first channel to the outer sidewall, and a second electrically conductive portion extends from the second channel to the outer sidewall. The first electrically conductive portion provides a first electrically conductive path between the first channel and the outer sidewall and the second electrically conductive portion provides a second electrically conductive path the second channel and the outer sidewall. The second electrically conductive path is separate from the first electrically conductive path. Devices and methods relate to surgical ports.

A treatment device used together with an endoscope, has a guide pipe and a movement mechanism. The guide pipe has a first pipe having a curving portion and a second pipe continuous with a proximal side of the curving portion. The curving portion has, in its inner circumferential surface, a bent surface bent to the second pipe, and bending the flow direction of the fluid discharged from the distal end of the sheath in a state where the distal end of the sheath is located near the distal end of the second pipe. The movement mechanism protrudes a distal surface of the insertion portion from the distal end of the sheath and brings the distal surface closer to or into abutment with the bent surface in a state where the distal end of the sheath is disposed near the distal end of the second pipe.

A laparoscopic medical device includes an oximeter sensor at its tip, which allows the making of oxygen saturation measurements laparoscopically. The device can be a unitary design, wherein a laparoscopic element includes electronics for the oximeter sensor at a distal end (e.g., opposite the tip). The device can be a multiple piece design (e.g., two-piece design), where some electronics is in a separate housing from the laparoscopic element, and the pieces (or portions) are removably connected together. The laparoscopic element can be removed and disposed of; so, the electronics can be reused multiple times with replacement laparoscopic elements. The electronics can include a processing unit for control, computation, or display, or any combination of these. However, in an implementation, the electronics can connect wirelessly to other electronics (e.g., another processing unit) for further control, computation, or display, or any combination of these.

The present application disclosed a single-piece hysteroscope instrument operation propeller, which includes a propelling body that can be attached to the hysteroscope body, the instrument can smoothly pass through the blind areas such as the vagina and cervical canal along the hysteroscope body that has already entered with the help of the groove on the propelling body, and can be operated continuously and flexibly after being sent into the uterus. The present application is beneficial for doctors to quickly, accurately and non-invasively send the treatment instrument into the uterus, which not only reduces the treatment cost, but also achieves a good treatment effect.

A surgical sheath system having a sheath with a hollow shaft; and a head coupled to and in fluid communication with the hollow shaft, the head having a first mounting feature for coupling a first surgical device; and a second mounting feature for coupling a second surgical device, the second surgical device being a different type of surgical device than the first surgical device.
