Abstract
A mounting member for a surgical stapler is fabricated from a plastic. The mounting member has a proximal end portion and a distal end portion. The proximal end portion has a pair of vertical projections configured to be coupled to a proximal body portion of a loading unit of a surgical stapler. The distal end portion includes a pair of walls extending distally from the proximal end portion. Each wall has a boss and a strut. The boss defines a transverse bore therethrough configured to be rotatably coupled to a cartridge assembly of the loading unit. The strut extends from the proximal end portion to the boss.
Claims15
A mounting member for a surgical stapler, comprising:
- a body fabricated from a plastic and defining a longitudinal axis, the body including:
- a proximal end portion having a pair of vertical projections configured to be coupled to a proximal body portion of a loading unit of a surgical stapler;
- and
- a distal end portion including:
- a pair of walls extending distally from the proximal end portion;
- a boss coupled to one wall of the pair of walls and defining a bore therethrough configured to be rotatably coupled to a cartridge assembly of a loading unit;
- and
- a strut extending from the proximal end portion to the boss.
A loading unit, comprising:
- a proximal body portion defining a longitudinal axis;
- a tool assembly extending distally from the proximal body portion and including:
- a cartridge assembly;
- and
- an anvil assembly fixed to a distal end of the proximal body portion;
- and
- a mounting member fabricated from a plastic and including:
- a proximal end portion having a pair of vertical projections coupled to the distal end of the proximal body portion;
- a distal end portion including:
- a pair of walls extending distally from the proximal end portion;
- a boss coupled to one wall of the pair of walls and defining a bore therethrough;
- and
- a strut extending from the proximal end portion to the boss;
- and
- a fastener extending through the cartridge assembly and the bore of the boss to rotatably couple the cartridge assembly to the mounting member.
