A kind of probe unit is disclosed, a kind of medical instrument is having the same, and control probe unit, and wherein medical probe device includes a main body It is separably provided in main body with a head, and including transducer array, for exporting ultrasound diagnosis object, the ontology includes. Transceiver is configured to send and receive transmission signal and transducer array passes through multiple channels With at least one processor, control transceiver is configured to emit scheduled test signal and be mounted on main body to the head of transducer array, determine that probe-type corresponds to the head of the installation of transducer array based on received feedback signal, by transceiver in response to test signal, and probe apparatus operation is made to correspond to identified sonde-type. Therefore, there are energy converter various shapes to be selectively installed at ultrasonic probe, and operation is automatically optimized to the sonde-type of installation and is possible to not need additional component or cost.
