Shockwave therapy apparatus

Abstract

The invention discloses a shockwave therapy apparatus. The apparatus includes a main body, a cavity channel, a therapy head, a bullet body and an air control device, the cavity channel is mounted in the main body, and the therapy head is fitted at the output end of the cavity channel; a first two-way airway and a second two-way airway are formed in the main body, two ends of the first two-way airway communicate with the input end of the cavity channel and the air control device, two ends of the second two-way airway communicate with the output end of the cavity channel and the air control device, and the bullet body is movably fitted in the cavity channel and is driven by air; when the air control device controls the first two-way airway to intake air and the second two-way airway to exhaust air, the air pushes the bullet body to impact the therapy head to generate shockwaves; and when the air control device controls the first two-way airway to exhaust air and the second two-way airwayto intake air, the air pushes the bullet body to return to the input end of the cavity channel. The apparatus makes the bullet body move into place in the therapy head shocking process or the returnprocess, and realizes the shock buffering and accurate return of the bullet body in order to achieve the stable, durable and efficient therapy effect.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a shock wave therapy device. 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] The existing air pressure shock type shock wave treatment device is to install a projectile body in the cavity, input compressed air to the input end of the cavity through the air control device, ...

AI Technical Summary

Problems solved by technology

[0004] The shock wave therapy device with the above structure has the following disadvantages: when the bullet body moves to the treatment head, the air between the two will be compressed, resulting in a relatively large air pressure, which will generate resistance against the movement of the bullet body, and it will be easy to press too much pressure on the treatment head. Cause damage; the bullet body is reset by the reverse air pressure in the cavity. With the aging of the treatment head, the bullet body is difficult to reset in place, affecting the impact energy and impact depth, resulting in the gradual deterioration of the treatment effect of the shock wave therapy device during use
