END EFFECTOR FOR SURGICAL INSTRUMENT, SURGICAL INSTRUMENT, AND METHOD FOR FORMING THE END EFFECTOR

摘要

PROBLEM TO BE SOLVED: To provide an improved jaw assembly that grasps tissue better, travels inside a working channel of an endoscope (or other scope), and is easier to manufacture with decreased cost.;SOLUTION: An end effector for an endoscopic surgical instrument having a longitudinal body with proximal and distal ends and an actuator at the proximal end of the body includes a clevis to be connected to the distal end of the body and two jaws. Each of the jaws 220 has a tang portion 240 pivotally connected to the clevis and to be connected to the actuator for pivoting the jaw 220. The jaw 220 has: a body portion 221 with a lateral side 223 having substantially straight opposing edges and with a proximal portion 227 connecting the lateral side to the tang portion; and nose portions 225, 229 connected to the lateral side and having substantially linear edges at an angle to the edges of the lateral side.;COPYRIGHT: (C)2012,JPO&INPIT
