Abstract
A shaft for a surgical instrument includes a tubular shaft and an end effector comprising a pair of jaw members. The end effector is formed by laser cutting a distal end of the tubular shaft to form the jaws and to form a pivot. The pivot enables movement of the a jaw about the pivot relative to a more proximal portion of the shaft.
Claims5
A shaft for a surgical instrument comprising:
- a tubular shaft and an end effector comprising a pair of jaw members, the end effector formed by laser cutting a distal end of the tubular shaft to form the jaws and to form a pivot, the pivot enabling movement of the a jaw about the pivot relative to a more proximal portion of the shaft.
A method of making a surgical instrument shaft, comprising the steps of:
- providing an elongate tube;
- laser cutting a pair of jaws into the elongate tube to create a distal end effector on a proximal portion of the tube;
- laser cutting a pivot between each jaw member and the proximal portion of the tube.
The method of claim 5, further comprising the step of laser cutting an articulation joint in the proximal portion of the tube.
