  • Surgical device with removable end effector
    Publication number: 20080021278
    Abstract: A surgical device and end effector connection system therefor include an easy-to-engage mechanism for connecting a handle/shaft/actuation rod unit to an end effector. This mechanism may utilize an axially engageable inner ball/socket inner connection with a threaded outer connection, or an inner bayonet connection with either an outer bayonet connection or an outer threaded connection. In each of the embodiments, an outer portion of the end effector preferably is statically engaged with the shaft, and an inner portion of the end effector is engaged with the actuation rod such that axial movement of the actuation rod can actuate a tool end of the end effector. The present invention further relates to methods of use for the laparoscopy device.
