Ballistic extracorporeal shock wave therapeutic instrument

Abstract

The invention discloses a ballistic extracorporeal shock wave therapeutic instrument and belongs to the medical instrument technical field. The therapeutic instrument comprises a shock wave gun and an air source; the shock wave gun comprises a handle; an airway is formed in the handle; the airway is communicated with an air connection opening; a gun barrel is fixedly connected with the handle or the gun barrel and the handle are integrally arranged; the gun barrel is communicated with the airway; a shock projectile is arranged in the gun barrel in a clearance fit manner; the rear end of the gun barrel is provided with a hollow round elastic cushion; the inner diameter of the elastic cushion is smaller than the inner diameter of the gun barrel and is larger than the outer diameter of the shock projectile; the front end of the gun barrel is provided with a massage head in an axial sliding manner; the massage head is arranged at the front end of the gun barrel in an axial limiting manner; the front end of the gun barrel is provided with a massage head resetting device; the air source is connected with the air connection opening of the handle through an air path; a control valve is arranged on the air path; and a control system is arranged in the therapeutic instrument. The ballistic extracorporeal shock wave therapeutic instrument of the invention has the advantages of simple structure, easiness in manufacture, low manufacturing cost and excellent use effect.

Description

technical field [0001] The invention relates to a shock wave therapeutic apparatus, in particular to a ballistic extracorporeal shock wave therapeutic apparatus, which belongs to the technical field of medical instruments. Background technique [0002] Extracorporeal shock wave is a kind of mechanical wave generated by electronic hydraulic device, electromagnetic device, pneumatic projectile, etc. It can play a role in solid and liquid substances and human tissues, and can promote bone cells in fracture ends, bone defect areas and osteonecrosis areas. It has become a new non-invasive treatment method in the field of orthopedics in recent years, and has achieved positive results in the treatment of intractable bone and soft tissue diseases such as frozen shoulder, tennis elbow, fracture nonunion, avascular necrosis of the femoral head, and heel pain. treatment effect. [0003] Most of the existing extracorporeal shock wave therapy instruments use hydraulic shock wave and ele...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing extracorporeal shock wave therapy instruments use hydraulic shock wave and electromagnetic shock wave sources, which have the disadvantages of large volume, high noise, poor stability, and high cost. Few of them use pneumatic shock wave therapy. The Chinese patent "extracorporeal shock wave therapy handle" ( Application number: 200920278648.X, publication (announcement) number: CN201519177U, publication (announcement) date: July 7, 2010), an extracorporeal shock wave therapy handle, which uses high-pressure pulsed gas to generate shock waves to specific parts of the patient Treatment, the technical solution of this patent is connected with the air pump through the trachea, including: the air cylinder, the tail end of the air cylinder is sealed and connected with the ventilation pipe; the air cylinder sleeve is set on the outside of the air cylinder; Connection; and the striking head, which can be moved back and forth and placed in the fixing part, and the front end protrudes out of the money port of the fixing part

This shock wave therapeutic apparatus has the following defects: the one is that although the pneumatic shock wave is adopted, the impact force produced is relatively small because the gas directly impacts on the percussion head. Aging; second, it requires a large amount of gas, and has higher requirements on the air pump; third, the area of ​​the therapeutic instrument that needs to withstand high pressure is large and there are many parts, which increases the manufacturing cost; fourth, the therapeutic instrument has high requirements for sealing, and More sealing parts will increase the cost
