Ultrasonic frequency conversion handheld shock wave physiotherapy machine

Abstract

The invention discloses an ultrasonic frequency conversion handheld shock wave physiotherapy machine, and belongs to the field of medical instruments. An ultrasonic frequency conversion handheld shock wave physical therapy machine comprises a physical therapy machine body and a handle, the side wall of the physical therapy machine body is fixedly connected with a take-up shell, a hollow pipe is rotatably connected in the take-up shell, the side wall of the hollow pipe is provided with a wire outlet hole, the handle is connected with a wire, and the wire outlet hole is communicated with the wire outlet hole. The end, away from the handle, of the wire penetrates through the wire outlet hole, extends to an inner cavity of the hollow pipe and is electrically connected with the physiotherapy machine body, the wire penetrates through the wire collecting shell, and the hollow pipe is provided with a limiting mechanism used for limiting free rotation of the hollow pipe. Through the arrangement of the take-up shell, the hollow pipe and the limiting mechanism, the wire can be taken up and paid off conveniently, winding of the wire or winding of the wire and an external object is avoided, the risk of wire damage is reduced, and the service life of the wire is prolonged.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an ultrasonic frequency conversion handheld shock wave physiotherapy machine. Background technique [0002] Ultrasound technology is playing a huge role in the medical field. With the advancement of science, it will be more perfect and better benefit human beings. The working principle of medical ultrasonography is similar to that of sonar, that is, sending ultrasonic waves to people In the body, when it encounters an interface in the body, it will reflect and refract, and may be absorbed and attenuated in human tissue, because the shape and structure of various tissues in the human body are different, so its reflection and refraction and absorption of ultrasonic waves The degree is also different. Doctors distinguish them through the waveforms, curves, or image characteristics reflected by the equipment. In addition, combined with anatomical knowledge, normal and pathological ch...
