1. A surgical device, comprising:
- (a) a transducer module having a proximal end and a distal end;
(b) a shaft assembly having a proximal end and a distal end, wherein the proximal end of the shaft assembly is configured to be removably coupled with the distal end of the transducer module, wherein the transducer module is operable to transmit energy to at least part of the shaft assembly; and
(c) a housing presenting an upwardly presented open upper recess, wherein the upwardly presented open upper recess is defined at least in part by a lower platform and a pair of opposing wall portions, wherein the opposing wall portions terminate at upwardly presented and exposed upper edges, wherein the upwardly presented open upper recess is configured to removably receive the transducer module, wherein at least one of the platform or the pair of opposing wall portions supports the transducer module, wherein an upper portion of the transducer module extends upwardly relative to a vertical position of the upper edges such that the upper portion of the transducer module is exposed above the upper edges.

Abstract
An ultrasonic surgical device comprises a detachable transducer module, a handle, and a shaft assembly. The shaft assembly includes an end effector having a harmonic blade. The transducer module is removably coupled with the shaft assembly to form an active assembly. The active assembly is removably coupled with the handle. The handle may include a resilient wall structure that deflects outwardly to receive the active assembly in a snap fit. The handle may include a pivoting latch feature to selectively retain the active assembly relative to the handle.

16. A surgical device, comprising:
-
(a) an active assembly, the active assembly comprising; (i) a transducer module having a proximal end and a distal end, and (ii) a shaft assembly having a proximal end and a distal end, wherein the proximal end of the shaft assembly is configured to be removably coupled with the distal end of the transducer module; and (b) a handle having a body section, the body section comprising wall portions and a platform wherein the wall portions terminate at upper edges, wherein the upper edges are upwardly presented and exposed, wherein the wall portions define an upwardly presented open recess with the platform being upwardly exposed, wherein the transducer module is configured to fit in the recess, between the upper edges and above the platform. - View Dependent Claims (17, 18)
