Shockwave therapy probe and shockwave therapy handle

Abstract

The invention discloses a shock wave treatment probe and a shock wave treatment handle. The treatment probe includes a probe shell, and an extended shock cavity is arranged inside the probe shell. The side wall of the impact chamber is provided with a conduction slot; the probe shell is also provided with a first auxiliary air channel and a second auxiliary air channel which are connected to the conduction slot and the extended impact chamber respectively. The other ends of the secondary air passages are sealed and communicated with the first air passage and the second air passage respectively; a coupling end is installed in the extended impact chamber so as to engage and slide axially; the coupling end is fixed with an active end, which is located at the coupling The portion between the end and the end surface of the extended impact chamber is also set with an air bag, and an air bag spring is installed inside the air bag, and the air bag is elastic and communicates with the second auxiliary air channel inside. The invention has a simple structure, can realize high-frequency shock wave output, and does not need an external electromagnetic reversing valve, which can greatly save costs.

Description

technical field [0001] The invention relates to medical equipment, in particular to a shock wave treatment probe and a shock wave treatment handle. Background technique [0002] The use of shock waves in treatment has been a very common technology and means, such as a treatment probe and a shock wave treatment handle for applying shock waves to tissues in the body disclosed in the Chinese invention patent application with the publication number CN106466199A. [0003] The current shock wave therapy mainly uses a gas-driven impactor to strike the coupling end, thereby forming resonance, and finally forms a shock wave, and then directly acts on the affected part through the shock wave through the action end. In order to obtain high-frequency shock waves, it is necessary to frequently switch the air supply direction of the collider, so that the collider hits the coupling end and then returns to the original position, and so on. At present, this function is mainly realized throu...

AI Technical Summary

Problems solved by technology

At present, this function is mainly realized through the external electromagnetic reversing valve, but because the switching frequency is very fast, the switch used to control the reversing of the electromagnetic reversing valve has no time to respond. If the electromagnetic reversing valve is used to reversing on time, this cannot be obtained. Higher frequency impact, because different air pressures drive the impactor at different speeds, once the speed of reversing is too fast, it is very likely that the impactor will move in the opposite direction before it hits the coupling end, resulting in shock wave coupling failure
