摘要： A surgical instrument is disclosed. The surgical instrument includes a handle assembly, a drive assembly, an endoscopic portion, a pair of jaw members, a dynamic clamping member, and a tissue stop. The drive assembly is disposed in mechanical cooperation with a movable handle of the handle assembly. The endoscopic portion defines a first longitudinal axis. The jaw members are each longitudinally curved with respect to the longitudinal axis. The dynamic clamping member is disposed in mechanical cooperation with a distal portion of the drive assembly and includes an upper beam, a lower beam, and a vertical beam having a cutting edge on a distal portion thereof. At least a portion of the dynamic clamping member is longitudinally curved with respect to the longitudinal axis. The tissue stop is disposed adjacent a distal portion of the first jaw member and configured to impede tissue from distally escaping the jaw members.

摘要： A surgical instrument is disclosed. The surgical instrument includes a handle assembly having a movable handle; an endoscopic portion extending distally from the handle and defining a longitudinal axis; a pair of jaw members; and a drive assembly. The jaw members are disposed adjacent a distal end of the endoscopic portion and extend generally distally therefrom. Each jaw member is longitudinally curved with respect to the longitudinal axis. At least one jaw member is movable with respect to the other between open and approximated positions. A first jaw member includes a channel having a longitudinally-extending slot therein. The drive assembly is advanced distally through at least a portion of the length of the jaw members in response to at least a partial actuation of the movable handle. A lower portion of the drive assembly is configured and dimensioned to travel at least partially within the longitudinally-extending slot of the channel.

摘要： The present disclosure relates to access systems which may be percutaneously or otherwise introduced while in a narrow diameter configuration and, which after introduction, may be radially expanded to accommodate passage of larger diameter surgical instruments therethrough. According to an aspect of the present disclosure, a radially expandable sleeve component, for use with an access system, is provided. The sleeve component includes a handle having a passage therethrough; and a sleeve body having a proximal end connected to the handle, a distal end, and an axial lumen aligned with the passage of the handle, the sleeve body having a length. The sleeve body is constructed from a radially expandable braid, wherein the braid is formed of a mesh of non-elastic filaments which axially shortens the length of the sleeve body as the sleeve body is radially expanded. The distal end of the sleeve body is flared radially outward.

摘要： An electrosurgical instrument includes a housing having a shaft attached thereto which connects a pair of first and second jaw members such that the jaw members are movable relative to one another to grasp tissue therebetween. The instrument also includes a four-bar handle assembly attached to the housing for actuating a drive rod assembly. The handle assembly includes a handle and a cam-like piston which cooperate to impart a uniform closure pressure against tissue grasped between the jaw members. The instrument also includes a rotating assembly for rotating the jaw members, a knife assembly for separating tissue and a pair of electrical leads connect the jaw members to a source of electrical energy. The electrical leads include slack loops disposed in the rotating assembly which permit rotation of the jaw members about the axis.

摘要： An access apparatus for use during a surgical procedure to provide access to the interior of the body includes an access member defining a longitudinal axis and having a proximal end for being disposed at an exterior side of the body and a distal end for extending into the interior of the body. The access member has a bore therethrough dimensioned to permit passage of an object. A seal is disposed within the bore of the access member. The seal includes a fabric material and an elastomeric material, and defines an internal passageway dimensioned to form a substantial sealing relation with an object inserted therethrough.

摘要： An apparatus and method for the biopsy of tissue specimens and, more particularly, a single insertion multiple sample percutaneous biopsy apparatus and method are provided. A tip at a distal end of a support tube is introduced into a tissue mass. The support tube has a lateral opening adjacent the tip. A knife tube is disposed within the support tube and is retracted allowing the lateral opening to communicate with the tissue mass. Suction through a suction tube draws tissue into the lateral opening where it is severed placing the tissue in a pusher. Pusher is attached to vacuum tube which is retracted proximally through the knife tube. A tissue sample is drawn through the knife tube to a location where it can be removed from the pusher.
