Abstract
A probe instrument which is formed having a unitary housing with indented switch actuating surfaces intended for surgical procedures employs internally disposed piezoelectric switching components within an elongate internally disposed switch receiving channel. The forward end of the instrument supports a crystal containing detector assembly with a preamplifier and associated leads which extend within a detector signal channel spaced from the switch receiving channel and protected therefrom by a shield wall. The piezoelectric components are held in preloaded association adjacent outwardly disposed switch actuating surfaces by a dual wedge switch support assembly. An elongate cable is permanently attached to the rearward end of the housing component through the utilization of a medical grade silicone seal and relief component.
