SURGICAL INSTRUMENT WITH SEPARABLE COAXIAL JOINT

摘要

PROBLEM TO BE SOLVED: To provide a surgical instrument for ensuring proper mechanical and electrical connections made between the reusable and replaceable components for treating tissue.

SOLUTION: The surgical instrument includes an elongated shaft having a proximal structural member and a proximal drive member that is selectively movable with respect to the proximal structural member. A modular end effector is removably coupled to the elongated shaft, and has a distal structural member and a distal drive member that is operatively coupled to a pair of jaw members. A separable joint is defined between the elongated shaft and the end effector. The separable joint includes laterally prominent and laterally indented portions of each of the proximal and distal structural members and of each of the proximal and distal drive members.
