Abstract
An ultrasonic surgical device comprises a handle assembly, a shaft assembly, and a removable transducer module. The transducer module includes a waveguide, a locking mechanism, and an electronics assembly including at least one button. The handle assembly includes a trigger assembly configured to actuate the button(s) of the electronics assembly when the transducer module is coupled with the handle assembly. The shaft assembly engages the waveguide of the transducer module and is disposed at the distal end of the handle assembly. The distal end of the shaft assembly includes a harmonic blade. When assembled with the handle assembly, the transducer module is capable of providing ultrasonic energy to the harmonic blade.

21. A surgical device, comprising:
-
(a) a detachable module comprising a transducer operable to convert electrical power into ultrasonic vibrations, wherein the detachable module further comprises an electronics assembly, wherein the electronics assembly comprises at least one button, wherein the at least one button is configured to actuate to thereby cause the transducer to convert electrical power into a at least one corresponding level of ultrasonic vibrations; (b) a body, comprising; (i) a housing having a distal end and a proximal end, wherein the housing is configured to removably receive the detachable module, (ii) a shaft assembly extending distally from the distal end of the housing, and (iii) a trigger assembly movably coupled with the housing, wherein the trigger assembly comprises at least one lever member, wherein the at least one lever member is operable to directly engage a corresponding button of the at least one button so as to selectively activate the transducer at an associated level of ultrasonic vibrations; and (c) a locking feature operable to selectively secure the detachable module to the body. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31)

32. A surgical device, comprising:
-
(a) a detachable transducer module, the detachable transducer module comprising; (i) one or more piezoelectric elements operable to convert electrical power into ultrasonic vibrations, and (ii) a switch assembly in communication with the one or more piezoelectric elements, wherein the switch assembly comprises at least one button, wherein the at least one button is operable to selectively activate the one or more piezoelectric elements, wherein the transducer module is operable to selectively toggle the one or more piezoelectric elements between a first power level and a second power level, wherein the first power level is different from the second power level; (b) a housing having a distal end and a proximal end, wherein the housing is configured to selectively engage the detachable transducer module; (c) a shaft assembly extending distally from the distal end of the housing, wherein at least part of the shaft assembly is configured to receive ultrasonic vibrations communicated from the detachable transducer module; and (d) a trigger assembly movably coupled with the housing, wherein a portion of the trigger assembly is operable to selectively directly contact the switch assembly when the detachable transducer module is engaged with the housing to thereby activate the one or more piezoelectric elements. - View Dependent Claims (33, 34, 35, 36)

37. A surgical device, comprising:
-
(a) a detachable module comprising; (i) a transducer operable to convert electrical power into ultrasonic vibrations, and (ii) an electronics assembly extending from the transducer, wherein the electronics assembly comprises a first button and a second button, wherein the first button is configured to actuate to thereby cause the transducer to convert electrical power into ultrasonic vibrations, wherein the second button is configured to provide at least a first energy level of ultrasonic vibrations; and (b) a body, comprising; (i) a housing, wherein the housing is configured to removably receive the detachable module, (ii) a shaft assembly extending distally from the housing, and (iii) a trigger assembly movably coupled with the housing, wherein the trigger assembly comprises a first trigger and a second trigger, wherein the first trigger comprises a first lever member operable to make direct contact with the first button, wherein the second trigger comprises a second lever member operable to make direct contact with the second button. - View Dependent Claims (38, 39, 40)
