Abstract
A surgical instrument includes a pulley rotatable about a pivot pin and an end effector coupled to the pivot pin. The instrument also includes a cable wound at least partially around the pulley and configured to actuate the end effector. The cable and/or any of the pulley components (e.g., the pulley, the pivot pin, etc.) includes a first coating having tungsten disulfide.
Claims20
A surgical instrument comprising:
- a pulley rotatable about a pivot pin;
- an end effector coupled to the pivot pin;
- and
- a cable wound at least partially around the pulley and configured to actuate the end effector, wherein the cable includes a first coating having tungsten disulfide.
1 more element
A system for coating a surgical instrument cable, the system comprising:
- a mold including a first portion and a second portion defining a mold cavity configured to receive the surgical instrument cable, wherein the mold cavity includes a plurality of detents running along a length of the mold cavity;
- a source of a liquid material for forming a coating on the surgical instrument cable inside the mold cavity;
- and
- a gate manifold configured to distribute the liquid material through the mold cavity to form the coating on the surgical instrument cable.
1 more element
A method for coating a surgical instrument cable, the method comprising:
- placing a surgical instrument cable into a mold including a first portion and a second portion defining a mold cavity configured to receive the surgical instrument cable, wherein the mold cavity includes a plurality of detents running along a length of the mold cavity;
- and
- supplying a liquid material to the mold cavity to form a coating on the surgical instrument cable.
