MODULAR POWERED SURGICAL INSTRUMENT WITH DETACHABLE SHAFT ASSEMBLIES

摘要

An interchangeable shaft assembly for a surgical instrument that includes first and second drive systems. The interchangeable shaft assembly is configured for removable attachment to a housing of the surgical instrument. Various embodiments include a latch system that enables the interchangeable shaft assembly to be detached from the housing when the first drive system is unactuated but prevents the interchangeable shaft assembly from being detached from the housing when the first drive system is in an actuated position.

主权项

1. A surgical instrument, comprising:
a housing; an interchangeable shaft assembly removably couplable to the housing, the interchangeable shaft assembly including an end effector comprising:
a first end effector portion operably responsive to first drive motions applied thereto; anda second end effector portion operably responsive to second drive motions applied thereto and wherein the surgical instrument further comprises: a first drive system operably supported by the housing, the first drive system movable from a first unactuated position to a second actuated position, the first drive system being configured to apply the first drive motions to the interchangeable shaft assembly operably coupled to the housing when the first drive system is in the second actuated position; a second drive system operably supported by the housing, the second drive system movable from an unfired position to a fired position, the second drive system being configured to apply the second drive motions to the interchangeable shaft assembly when the second drive system is in the fired position; and a latch system for removably coupling the interchangeable shaft assembly to the housing such that when the first drive system is in the first unactuated position, the interchangeable shaft assembly is detachable from the housing and when the first drive system is in the second actuated position, the latch system prevents the interchangeable shaft assembly from being detached from the housing.
