Patent ID: 7971776

Claim:
An ultrasonic instrument, comprising: a socket; and a front-end system, wherein the socket is provided with at least two probe model identification pins and a plurality of functional signal pins; wherein the front-end system comprises a decoding module, a switch selection module, and a probe driving control module; wherein the decoding module has its input terminals electrically connected to the probe model identification pins of the socket, and has its output terminal coupled to a control terminal of the switch selection module; wherein input terminals of the switch selection module are electrically connected to the functional signal pins of the socket, respectively, and in response to a probe identification signal outputted from the decoding module to the control terminal, the switch selection module establishes connection between its input terminals and a group of output terminals corresponding to the probe identification signal; and wherein the probe driving control module is electrically connected to the output terminals of the switch selection module.
