Surgical instrument with pivoting coupling to modular shaft and end effector

摘要

A surgical instrument comprises a body and a shaft assembly. The body includes an energy source such as an ultrasonic transducer. The shaft assembly comprises an end effector and a transmission member such as an acoustic waveguide. The end effector may include a harmonic blade and a pivoting clamp member. One or both of the body or the shaft assembly includes a pivot feature. The pivot feature is operable to secure the shaft assembly to the body. The pivot feature may include a bar defining a pivot axis about which the shaft assembly pivots to secure the shaft assembly to the body. The pivot axis may be perpendicular to a longitudinal axis defined by the shaft assembly. The pivot feature may also include a pivoting cover configured to cover a recess in the body in which a proximal portion of the shaft assembly is received.

主权项

1. A surgical instrument, comprising:
(a) a body; and (b) a shaft assembly configured to removably couple with the body, wherein the shaft assembly comprises:
(i) an end effector, and(ii) an acoustic transmission member in communication with the end effector, wherein the acoustic transmission member defines a longitudinal axis; wherein one or both of the body or the shaft assembly includes a pivot feature, wherein the pivot feature is operable to pivot the shaft assembly about an axis perpendicular to the longitudinal axis of the acoustic transmission member between an unsecured position and a secured position, wherein the pivot feature in the secured position is operable to secure the shaft assembly to the body such that the acoustic transmission member is positioned to transmit energy to the end effector, wherein the pivot feature in the unsecured position is configured to disconnect the transmission member from the energy source.
