摘要： A stapling device (10) includes a handle assembly (12) having a housing (18), a trigger (22), and an audible indicator mechanism (44) that provides an audible indication to a clinician after the trigger (22) is moved through a clamping stroke and after the trigger (22) is moved through a firing stroke. The audible indicator mechanism (44) includes a link (62), a clicker (64), and a retraction spring (66). The housing (18) of the handle assembly (12) defines a track (60) that has a triangular configuration and receives the clicker (64). The clicker (64) is movable through the track (60) to provide an audible indication to a clinician that the clamping and firing strokes are complete.

摘要： A stapling device (10) includes a handle assembly (12), an elongate body (14), a clamp slide member (66), and an end effector (16). The handle assembly (12) includes a movable trigger (22) and a cam member (700) operatively coupled to the movable trigger (22). The cam member (700) includes lateral walls (700a, 700b) that flexibly oppose each other and define a gap (710) between the lateral walls (700a, 700b). The lateral walls (700a, 700b) include respective camming protrusions (702a, 702b) extending towards each other. The clamp slide member (66) has a distal portion (68) that defines a curved pocket (77) and a proximal portion (69) that defines a cam slot (84) configured to slidably receive the camming protrusions (702a, 702b) of the cam member (700) such that actuation of the movable trigger (22) causes axial displacement of the clamp slide member (66). The end effector (16) is supported on the distal portion of the elongate body (14). The end effector (16) includes an end effector frame (56), an anvil assembly (11), and a cartridge assembly (50).

摘要： A surgical stapling device (10) includes a proximal handle assembly (12), an elongated central body portion (14) that extends distally from the proximal handle assembly (12) to a distal end portion, a tool assembly (16) supported on the distal end portion of the elongated central body portion (14), and an audible indicator mechanism (100) supported by the proximal handle assembly (12). The proximal handle assembly (12) includes a contact arm (129) and the audible indicator mechanism (100) includes a cam member (108). The cam member (108) contacts the contact arm (129) of the proximal handle assembly (12) as the cam member (108) moves between distal and proximal positions to generate an audible sound that indicates that the tool assembly (16) was fired.

摘要： A circular stapler reload (10) is disclosed that can be releasably coupled to a stapler actuation device (20) to facilitate reuse of the stapler actuation device (20). The circular stapler reload (10) includes a cartridge assembly (22) having an annular staple cartridge (122) supporting staples, a stationary anvil assembly (24), and an integrated approximation and firing assembly (60). The approximation and firing assembly (60) operates to advance the cartridge assembly (22) towards the anvil assembly (24) from a spaced position to a clamped position and includes a lockout (98) to prevent firing of the reload prior to movement of the cartridge assembly (22) to the clamped position. The reload (10) also includes a lockout (170) which prevents movement of a drive member (64) of the approximation and firing assembly (60) until the reload (10) is secured to the actuation device (20).

摘要： A surgical fastener applying instrument includes a handle assembly. The handle assembly includes a handle housing, a trigger, a drive mechanism and a trigger return mechanism. The trigger return mechanism includes a rack and a biasing member. The rack is disposed within the handle housing and movably connected to the drive mechanism. The biasing member has a first end connected to the rack and a second end in abutting engagement with a top inner surface of the handle housing. Movement of the trigger from an un-actuated configuration to an actuated configuration drives an actuation of the drive mechanism, which drives movement of the rack, to compress the biasing member between the rack and the top inner surface of the handle housing such that the trigger is resiliently biased to the un-actuated configuration.

摘要： Disclosed an anvil assembly and a tool assembly. An anvil assembly (20) comprising: an anvil shaft (36) defining a longitudinal axis and supports a first spline (38a), a second spline (38b), and a third spline (38c). Each of the first, second, and third splines includes a pair of tapered camming surfaces (42, 44) that meet at a proximal end of the respective spline to define an apex (46). The apex (46) of the first spline (38a) is positioned on the anvil shaft (36) at a location proximal of the apex (46) of the second spline (38b), and the apex (46) of the second spline (38b) is positioned on the anvil shaft (36) at a location proximal of the apex (46) of the third spline (38c). In embodiments, each of the splines includes an apex (46). The apex (46) of the first spline (38a) is aligned with a longitudinal axis of the first spline (38a) and the apex (46) of the second and third splines are aligned with a longitudinal axis of the second and third splines, respectively.
