摘要：
An adapter (200 ') for selectively interconnecting a surgical end effector (300) that is configured to perform a function and a handle assembly (102) that is configured to operate the end effector, in which the effector of end includes at least one axially movable drive member (374), and in which the handle assembly includes at least one swivel drive shaft (212), wherein the adapter comprises: a configured adapter housing (202 ') and adapted for connection with the handle assembly and to be in operational communication with each rotating drive shaft of the handle assembly； an outer tube (206) having a proximal end (204) and a distal end (205), in which the distal end of the outer tube is configured and adapted for connection with the end effector (300) and for communication operative with each axially movable drive member of the end effector； an inner housing (262 ', 264') having proximal and distal ends defining a longitudinal axis in which the inner housing is rotatably supported in the adapter housing； and at least one drive converter assembly for connecting to each other a respective rotating drive shaft of the handle assembly and an axially movable drive member of the end effector, wherein the at least one drive converter assembly includes a first end which it can be connected to a rotating drive shaft of the handle assembly and a second end that can be connected to the axially movable drive member of the end effector, in which the at least one drive converter assembly converts and transmits a shaft rotation rotational drive of the handle assembly to an axial displacement of the axial assembly axially movable drive member of the end effector； characterized in that the adapter housing (202 ') has an inner wall surface defining a cavity, in which a flange (203') protrudes radially inwardly from the inner wall surface at the distal end of the housing adapter； the outer tube (206) narrows distally from a larger diameter to a smaller diameter, in which the outer tub
