Ultrasonic surgical instrument with modular end effector
First Claim
1. A surgical instrument comprising:
- (a) a transmission assembly having a proximal end, the transmission assembly extending along a longitudinal axis and comprising;
(i) a waveguide having a proximal end and a distal end, and(ii) an end effector coupled to the distal end of the waveguide;
(b) a transducer; and
(c) a body assembly having a transmission aperture, wherein the proximal end of the transmission assembly is insertable into the transmission aperture of the body assembly, the body assembly comprising a locking mechanism, wherein the locking mechanism includes a moving feature that is movable between a locked position and an unlocked position, wherein the moving feature is configured to engage the transducer in the locked position when the transmission assembly is inserted into the transmission aperture.

Abstract
A surgical instrument having a transmission assembly, a transducer, and a handle assembly is configured for coupling the transmission assembly to the handle assembly using a locking mechanism. The locking mechanism is operable to restrict the rotational movement of an actuator coupling member and the transducer relative to the handle assembly. The locking mechanism may also be operable to lock a trigger of the handle assembly in a first position. An inner tubular actuating member of the transmission assembly may be threadably attachable to the actuator coupling member or the actuator coupling member may include a latching mechanism to couple to a flared portion of the inner tubular actuating member. A waveguide of the transmission assembly may also be threadably attachable to the transducer. In one alternative, the trigger may be configured to operate the locking mechanism, either in the first position or when pivoted distally to a third position.

16. A method of assembling a surgical instrument, the surgical instrument comprising:
-
(a) a transmission assembly having a proximal end, the transmission assembly extending along a longitudinal axis and comprising; (i) a waveguide having a proximal end and a distal end, and (ii) an end effector coupled to the distal end of the waveguide; (b) a transducer; and (c) a body assembly comprising a locking mechanism comprising a slider, wherein the slider is movable between locked and unlocked positions, wherein the slider is configured to engage the transducer in a locked position; wherein the method comprises; (a) moving the slider to a locked position to engage the transducer; (b) inserting the proximal end of the transmission assembly into the body assembly; and (c) moving the slider back to the unlocked position to disengage the transducer.

17. A surgical instrument comprising:
-
(a) a transmission assembly having a proximal end, the transmission assembly extending along a longitudinal axis and comprising; (i) a waveguide having a proximal end and a distal end, and (ii) an end effector coupled to the distal end of the waveguide; (b) a transducer; and (c) a body assembly comprising; (i) a transmission aperture formed in a distal surface of the body assembly and configured to receive a portion of the transmission assembly, and (ii) at least one friction member configured to selectively frictionally engage the transducer to prevent movement of the transducer. - View Dependent Claims (18, 19, 20)
