摘要： A reposable surgical instrument includes a handle assembly (100) and an endoscopic assembly (200, 300, 400, 500, 600, 700) releasably engagable with the handle assembly (100). The handle assembly (100) includes a housing (110), a drive bar (132) supporting a ratchet pawl (142), and a trigger (122) coupled to the housing (110) and the drive bar (132). The endoscopic assembly (200, 300, 400, 500, 600, 700) includes a proximal hub (210, 310, 410, 510, 610, 710) including a ratchet rack (215, 415, 515, 615), an elongated shaft (220, 340, 420) extending from the proximal hub (210, 310, 410, 510, 610, 710) and supporting an end effector assembly(350) at a distal end (344) thereof, and a drive assembly (230, 320, 430) operably coupled to the end effector assembly (350). In use, movement of the trigger (122) from an un-actuated position towards an actuated position translates the drive bar (132) from a proximal position towards a distal position to engage the ratchet pawl (142) with the ratchet rack (215, 415, 515, 615) such that further distal translation of the drive bar (132) towards the distal position incrementally urges the drive assembly (230, 320, 430) from the un-fired position towards the fired position.

摘要： A reposable endoscopic surgical clip applier includes a handle assembly (100) configured to releasably engage at least two different endoscopic assemblies (200,300,400). The handle assembly (100) is configured such that a ratcheting function thereof is disabled upon engagement of an endoscopic assembly (300) therewith that is not intended for ratcheting use and such that the ratcheting function is enabled upon engagement of an endoscopic assembly (400) therewith that is intended for ratcheting use. Endoscopic assemblies (200,300,400) for use with the handle assembly (100) are also provided.

摘要： A surgical instrument comprising a handle assembly, an elongated portion, a head portion, an approximation mechanism, and a lockout mechanism is disclosed. The handle assembly comprises a movable handle and a stationary handle. The elongated portion extends distally from the handle assembly and defines a longitudinal axis. The head portion is disposed adjacent a distal portion of the elongated portion, and comprises a first jaw member and a second jaw member. The approximation mechanism comprises a drive member disposed in mechanical cooperation with the first jaw member and is configured to longitudinally move the first jaw member in relation to the second jaw member. The lockout mechanism is configured to selectively permit actuation of the movable handle to eject fasteners from the second jaw member. The lockout mechanism comprises a pin extending from the movable handle and is slidingly engaged with a slot in the drive member.

摘要： A surgical stapling device includes a tool assembly having a U-shaped frame, an anvil assembly, and a cartridge assembly. The U-shaped frame has a proximal transverse portion, a longitudinal portion, and a distal transverse portion. The distal transverse portion and the proximal transverse of the U-shaped frame and the cartridge assembly have a common shape including a first linear portion defining a first axis, a second linear portion defining a second axis, and a third linear portion defining a third axis, the first axis being transverse to the longitudinal axis of the elongate body. In embodiments, a first radius of curvature is defined between the first linear portion and the second linear portion such that the first axis and the second axis define an angle β, and a second radius of curvature is defined between the second linear portion and the third linear portion such that the second axis and the third axis define an angle Ω.

摘要： A surgical device includes a handle assembly and a firing counter assembly. The handle assembly includes a housing defining a window, a trigger, and a drive member axially movable within the housing and operatively coupled with the trigger. The firing counter assembly includes a camming pin and a sleeve rotatably supported about the drive member and defining a continuous groove. The sleeve has indicia circumferentially arranged about the sleeve and corresponding to the number of surgical clips in the surgical device. The camming pin is supported on the drive member for concomitant axial displacement with the drive member. The camming pin is configured to slide through the continuous groove of the sleeve, wherein actuation of the trigger causes rotation of the sleeve such that the indicia corresponding to the number of surgical clips remaining in the surgical device is shown through the window of the housing.
