Abstract
A surgical fastener applying apparatus for applying fasteners to body tissue. The apparatus includes an anvil half-section having a distal anvil portion and a proximal handle portion and a cartridge receiving half-section having an elongated channel member. A firing assembly is releasably supported in the cartridge half-section and includes a locking member. A clamping lever having an engagement member engages a latch portion of the locking member to releasably retain the clamping lever in a clamped position.
Claims18
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, 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,
- a clamping lever secured to the cartridge receiving half-section, the clamping lever having a proximal portion and a distal portion and including a handle portion supporting an engagement member;
- and
- a firing assembly configured to be releasably supported within the proximal portion of the cartridge receiving half-section and including a stationary housing releasably received within the proximal portion of the cartridge receiving half section, a firing lever, a cam bar fixedly secured to the firing lever, and a pivotal locking member including a latch portion, the pivotal locking member being pivotally supported on a proximal end of the stationary housing;
- the clamping lever being operably associated with the anvil half-section and the cartridge receiving half-section and being movable from an unclamped 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, wherein in the clamped position, the engagement member of the clamping lever releasably engages the latch portion of the locking member to releasably retain the clamping lever in the clamped position.
