Description
Technical Field
[0001] The invention relates to the technical field of medical instruments, and in particular to a shock wave therapy instrument handle with energy detection. Background Art
[0002] The handle of the shock wave therapy device is the functional execution component of the pneumatic ballistic shock wave therapy device. The handle of the shock wave therapy device is provided with a cavity inside; a vibrator is provided in the cavity; the vibrator is driven by the high-pressure airflow to move back and forth at high speed in the cavity, hits the treatment head, and then generates shock waves, which are then coupled into the human body through the gun-type probe at the head end to achieve the treatment effect. However, the reciprocating movement of the vibrator inside the cavity will accelerate the wear of the vibrator surface and the cavity wall; when the wear of the vibrator surface and the wear of the cavity inner wall accumulate to a certain extent, the gap between the vibrator and the cavity wall will increase; the high-pressure airflow will release pressure through the enlarged gap; in this way, the shock wave energy generated by the impact of the vibrator will be reduced; and the treatment effect of the shock wave therapy handle will also be reduced. If the shock wave energy generated by the shock wave therapy device handle can be detected, the detection results can be visualized so that doctors can more intuitively judge the shock wave energy intensity and then judge whether the handle is faulty. If a fault occurs, parts can be replaced in time to avoid ineffective treatment due to equipment failure, further ensuring the treatment level of doctors operating the shock wave therapy handle and ensuring the treatment effect of patients.
