Abstract
A surgical instrument adapted for stapling and cutting tissue in a highly controlled manner is provided. The instrument comprises a frame with a handle at a proximal end and an end-effector at a distal end. The end-effector has a U-shaped supporting structure and receives a cartridge module containing a cartridge housing containing a plurality of surgical fasteners and a knife, both of which are selectively actuated by a firing mechanism. The cartridge module includes an anvil shaped for engagement with the surgical fasteners and knife to facilitate cutting and stapling. The cartridge housing and anvil are moveable relative to each other.
The instrument includes a retainer for preventing undesired movement of the cartridge housing towards the anvil.
The instrument includes a retainer for preventing undesired movement of the cartridge housing towards the anvil.
Claims (3)
1.~A surgical instrument adapted for stapling and cutting tissue in a highly controlled manner, comprising:
a frame having a proximal end and a distal end, with a handle positioned at the proximal end and an end effector positioned at the distal end;
the end effector includes a U-shaped supporting structure shaped and dimensioned for selectively receiving a cartridge module containing a plurality of surgical fasteners and a knife;
a firing mechanism associated with the end effector and the cartridge module for selective actuation of the surgical fasteners and knife for treatment of an individual;
the cartridge module includes a cartridge housing in which the surgical fasteners and knife are housed and an anvil shaped and dimensioned for engagement with the surgical fasteners and knife to facilitate cutting and stapling, the cartridge housing and anvil being relatively movable between a first spaced apart position and a second position in close approximation with one another; and a retainer selectively positioned between the anvil and the cartridge housing to prevent undesired movement of the cartridge housing toward the anvil.
a frame having a proximal end and a distal end, with a handle positioned at the proximal end and an end effector positioned at the distal end;
the end effector includes a U-shaped supporting structure shaped and dimensioned for selectively receiving a cartridge module containing a plurality of surgical fasteners and a knife;
a firing mechanism associated with the end effector and the cartridge module for selective actuation of the surgical fasteners and knife for treatment of an individual;
the cartridge module includes a cartridge housing in which the surgical fasteners and knife are housed and an anvil shaped and dimensioned for engagement with the surgical fasteners and knife to facilitate cutting and stapling, the cartridge housing and anvil being relatively movable between a first spaced apart position and a second position in close approximation with one another; and a retainer selectively positioned between the anvil and the cartridge housing to prevent undesired movement of the cartridge housing toward the anvil.
2. ~The surgical instrument according to claim 1, wherein the retainer includes a disengagement structure.
3. ~The surgical instrument according to claim 1, wherein the disengagement structure includes a tab which contact the end effector for release of the retainer upon insertion of the cartridge module within the end effector.
