First Claim
Patent Images
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 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 open upper recess, wherein the open upper recess is defined at least in part by a lower platform and a pair of opposing sidewalls,wherein the opposing sidewalls present a gap configured to removably receive the transducer module,wherein the at least one of the opposing sidewalls or the platform supports the transducer module.

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 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 (b) a handle having a body section, the body section comprising an opposing wall structure extending outwardly from an outer surface of the body section, the opposing wall structure defining an open upper recess, wherein the open upper recess is configured to removably receive the transducer module. - View Dependent Claims (17, 18)

19. A method of assembling and using a surgical device, the surgical device comprising a detachable transducer module, a shaft assembly having a knob, and a handle, the handle having a resilient wall structure, the method comprising:
-
(a) coupling a distal end of the detachable transducer module to a proximal end of the shaft assembly to form an active assembly; and (b) pressing the active assembly downwardly toward the handle, thereby deflecting the resilient wall structure outwardly, wherein the resilient wall structure resiliently deflects back inwardly upon completion of the act of pressing the active assembly downwardly toward the handle, to substantially retain the active assembly relative to the handle.

20. The method of claim 20, wherein the act of coupling the distal end of the detachable transducer module to a proximal end of the shaft assembly to form an active assembly comprises:
-
(i) gripping the knob and the detachable transducer module, and (ii) rotating the knob relative to the detachable transducer module.
