Abstract:
1. An ultrasonic medical device, comprising: a transducer configured to convert an electrical drive signal to mechanical motion at an ultrasonic frequency, the transducer having a first connector; a waveguide having a proximal end and a distal end, the proximal end having a second connector configured to mate with the first connector, the waveguide configured to receive the mechanical motion from the transducer and propagate the mechanical motion along the waveguide; and a coupling system comprising a frangible link, the coupling system being configured to attach the second connector of the waveguide to the first connector of the transducer, wherein the frangible link is fractured when a predetermined torque limit is reached wherein the coupling system further comprises a hinge assembly having a first position and a second position and wherein the hinge assembly comprises a first arm and a second arm connected by the frangible link.
