摘要： A surgical stapler includes a handle assembly and an end effector connected by an elongate body. The end effector includes a cartridge assembly having staples, an anvil to assist forming staples, and illuminating devices on the end effector capable of illuminating tissue. The illuminating devices on the end effector assist in both illuminating the tissue to be stapled and to visualizing blood vessels in the tissue, including veins.

摘要： A specimen retrieval device includes a tubular body defining a longitudinal bore, an inner shaft slidably disposed within the longitudinal bore of the tubular body, and a specimen bag affixed to a support mechanism at the distal portion of the inner shaft. The specimen retrieval device includes a drain tube that passes from within specimen bags and out of the specimen retrieval device that permits passage of fluids out of the specimen bag prior to removal of the device from the body.

摘要： A surgical access device includes a cannula assembly, a locking collar, a fixation sleeve assembly, and a tip portion. The cannula assembly includes a housing and a tubular member extending from the housing. The locking collar slidably is received on the tubular member. The fixation sleeve assembly is disposed about the tubular member. The fixation sleeve assembly includes a securing member configured to detachably engage the locking collar, and a sleeve extending distally from the securing member. The tip portion detachably is coupled to a distal portion of the tubular member to retain the fixation sleeve assembly on the tubular member. The fixation sleeve assembly is transitionable between a first configuration, in which, the sleeve has a tubular profile, and a second configuration, in which, the sleeve flexes radially outwards to define a fixation anchor configured to secure the surgical access device relative to an opening in tissue.

摘要： A trigger mechanism for a surgical instrument, particularly, a surgical stapling instrument provides significant mechanical advantages by increasing the length of the firing stroke of the surgical instrument while reducing the degree of movement of the trigger associated with the trigger mechanism. The trigger mechanism also reduces the forces required to actuate the trigger thereby enhancing usability and minimizing operator fatigue.

摘要： A surgical loading unit includes an anvil assembly, a staple cartridge assembly pivotably coupled to the anvil assembly, and a knife configured to approximate the staple cartridge assembly and the anvil assembly. The staple cartridge assembly has a staple cartridge chassis having a support protruding outwardly from a proximal end thereof. The knife includes an upper plate coupled to the staple cartridge chassis and a lower plate coupled to the anvil assembly. The support of the staple cartridge chassis has an upper surface that is coplanar with or above an upper surface of the upper plate when the knife is in a proximal position for preventing the knife from catching on a surgical port during use.
