Abstract
A method is used to manufacture a lower jaw of an end effector of a surgical instrument. The method includes providing a lower jaw that includes a U-shaped body portion. The U-shaped body portion includes a bottom wall interposed between first and second opposing side walls. The method also includes forming at least one feature into at least one of the first and second side walls, wherein the at least one feature has a near net shape. The method also includes subsequently machining the at least one feature to have a machined shape.
Claims20
A method of manufacturing a lower jaw of an end effector of a surgical instrument, the method comprising:
- (a) forming a lower jaw that includes a U-shaped body portion using at least one of stamping, additive manufacturing, selective laser melting, direct metal laser sintering, or metal injection molding, wherein the U-shaped body portion includes a bottom wall interposed between first and second opposing side walls;
- (b) forming at least one feature into at least one of the first and second side walls;
- and
- (c) subsequently machining the at least one feature.
A method of manufacturing a lower jaw of an end effector of a surgical instrument, the method comprising:
- (a) stamping a lower jaw of an end effector of the surgical instrument to include a U-shaped body portion, wherein the U-shaped body portion includes a bottom wall and opposing first and second side walls;
- (b) stamping the first wall to include a first proximal aperture, wherein the first proximal aperture has a first area prior to machining;
- (c) stamping the second wall to include a second proximal aperture, wherein the second proximal aperture has the first area prior to machining;
- and
- (d) subsequently machining the first and second proximal apertures to have second areas that are greater than the first areas.
A method of manufacturing a lower jaw of an end effector of a surgical instrument, the method comprising:
- (a) providing a lower jaw that includes a U-shaped body portion, wherein the U-shaped body portion includes a bottom wall interposed between first and second opposing side walls;
- (b) forming at least one feature into at least one of the first and second side walls;
- (c) subsequently machining the at least one feature to have a machined shape;
- and
- (d) coupling a lower longitudinally extending back to a bottom surface of the bottom wall.
