WRIST AND JAW ASSEMBLIES FOR ROBOTIC SURGICAL SYSTEMS
First Claim
1. An end effector of a surgical tool comprising:
- a pair of jaws pivotable about a first axis;
a first and a second cam pulley rotatable about a second axis parallel to the first axis and coupled to the pair of jaws; and
a cam follower coupling the first and the second pulleys to each of the pair of jaws;
wherein;
a rotation of the first cam pulley opens or closes the pair of jaws about the first axis; and
a force applied to the second cam pulley rotates the pair of jaws about the second axis.

Abstract
An end effector for use and connection to a robot arm of a robotic surgical system, wherein the end effector is controlled and/or articulated by at least one cable extending from a respective motor of a control device of the robot surgical system, is provided. The end effector includes a wrist assembly, and a jaw assembly. The jaw assembly includes a cam pulley rotatably supported on at least one support plate of the jaw assembly, wherein the cam pulley is operatively connected to a proximal end of each of the jaws of the jaw assembly such that rotation of the cam pulley results in one of an opening and closing of the jaw assembly.
