The present disclosure relates to a surgical fastener applying apparatus for applying fasteners to body tissue. The apparatus includes a cartridge receiving half-section defining an elongated channel member configured to releasably receive a firing assembly and a single use loading unit. A lockout structure prevents insertion of the single use loading unit into the channel member after the firing assembly is mounted to the cartridge receiving half-section. Alternatively, the lockout structure prevents full insertion of the firing assembly into the cartridge receiving half-section, if the single use loading unit is not engaged with the firing assembly.

Surgical fastener applying apparatus

A fastener applying apparatus () includes an anvil half-section () and a cartridge receiving half-section () having a distal portion dimensioned to releasably receive a single use loading unit ('SULU') () and a proximal portion configured to support a firing assembly (). The firing assembly includes a stationary housing () and a firing lever () having one or more lever guide projections (). The firing lever is slidable from a proximal end of the stationary housing to a distal end of the stationary housing to define a firing stroke. A clamping lever () is movable from an undamped position to a clamped position to releasably secure the distal anvil portion in close approximation with the SULU. The clamping lever defines one or more lever guide slots (). The lever guide projection(s) is positioned to enter the lever guide slot(s) upon initiation of the firing stroke to inhibit movement of the clamping lever to the undamped position during the firing stroke.

The present disclosure relates to a surgical fastener applying apparatus () for sequentially applying fasteners to body tissue. The apparatus includes a clamping half-section () having a distal anvil attachment portion () and a proximal handle portion (), a cartridge receiving half-section () having a handle portion () and an elongated channel portion (), the elongated channel portion being configured to releasably receive a single use loading unit and the handle portion being configured to releasably receive a firing assembly (), an anvil member () configured to be releasably supported within the distal anvil attachment portion of the clamping half-section and a firing assembly configured to be releasably supported within the handle portion of the cartridge receiving half-section.

A surgical fastener applying apparatus for applying fasteners to body tissue. The apparatus includes a cartridge receiving half-section defining an elongated channel member, an anvil half-section, and a clamping lever. The cartridge receiving half-section releasably receives a cartridge and a firing assembly. The clamping lever includes a protrusion in a sidewall which is receivable in a bifurcated depression formed in a sidewall of the cartridge receiving half-section to releasably retain the clamping lever in a non-clamped position and in a clamped position. The apparatus includes a disposable firing assembly and SULU.

The present disclosure relates to a surgical fastener applying apparatus comprising: an anvil half-section including a distal anvil portion and a proximal handle portion; a cartridge receiving half section defining an elongated channel member and including at least one hinge member () supported on a bottom wall of the elongated channel member, the elongated channel member having a distal portion dimensioned to releasably receive a single use loading unit and a proximal portion configured to support a firing assembly, and wherein the at least one hinge member defines an opening; and a clamping lever () pivotally secured to the cartridge receiving half-section, the clamping lever having a proximal end, a distal end and a pivot member () supported in cantilevered fashion on the distal end of the clamping lever; the pivot member of the clamping lever being slidably received within the opening of the at least one hinge member to pivotally secure the clamping lever to the cartridge receiving half-section, the clamping lever being movable from an undamped position to a clamped position to releasably secure the anvil portion of the anvil half-section in close approximation with the single use loading unit supported within the elongated channel member.

A surgical fastener applying apparatus for applying fasteners to body tissue including a cartridge receiving half-section defining an elongated channel member configured to releasably receive a stationary housing of a firing assembly. The stationary housing is dimensioned to releasably receive a single use loading unit therein, and includes a lockout structure that prevents insertion of the stationary housing into the cartridge receiving half-section if the single use loading unit is not mounted in the stationary housing.

A surgical fastener applying apparatus () including a cartridge supporting section (), an anvil supporting section () having a longitudinal axis and including a distal anvil portion () and a proximal handle portion (), including a first longitudinally extending slot () extending therealong. A clamping lever () having a proximal portion and a distal portion is movable from an undamped position to a clamped position to releasably secure the anvil supporting section in close approximation with the cartridge supporting section. A firing assembly () includes a firing knob (), the firing knob movable within the longitudinally extending slot from a first proximal position to a second distal position to fire fasteners () supported in the cartridge supporting section.
