Apparatus for treating biological tissue and method of generating shock-like pressure waves in such an apparatus

Abstract

The invention relates to a device for treating biological tissue, comprising a housing (4) in which is arranged a ballistic device for generating an extracorporeal shock wave-like pressure wave and a transmission element (2) permanently arranged on the biological tissue ), the transfer element couples the pressure wave into the living body, wherein the transfer element (2) couples the ballistically generated pressure wave in the form of a diffuse shock wave into the biological tissue, the pressure wave being driven by the shock member ( 10) produced, the impact member (10) is accelerated by the pneumatic medium under the working pressure in the pressure tank (6) to a high terminal velocity exceeding 5m / s, the impact member reciprocates and hits the transmission element (2 ), wherein the front part of the pressure groove (6) is connected with the back pressure chamber (8), when the impact member (10) is accelerated, the aerodynamic medium located at the front distal end of the impact member (10) can Flow into the back pressure chamber (8). The quick-acting valve (16) releases the pneumatic medium under working pressure into the pressure tank (6), wherein the control circuit (17) controls the opening time of the quick-acting valve (16), making the opening time as the following parameters A function of at least one or a combination of them: working pressure, impact frequency or the pressure inside the back pressure chamber (8).

Description

technical field [0001] The present invention relates to a device for treating biological tissue as defined in the preamble of claim 1 or 2 and to a device for generating shock waves in such a device as defined in the preamble of claim 14 or 15 Shaped pressure wave approach. Background technique [0002] Such an instrument is known from WO9857707, which utilizes shock-like divergent pressure waves to accelerate the healing process of fractures, enthesiopathies, tendinitis and also for periodontitis. Another area of ​​application is the treatment of pain in the soft tissue area of ​​the musculoskeletal system near the bones. [0003] Other known sources of pressure pulses for the same therapeutic purpose use focused shock waves and are only effective in a very limited focal zone. However, in order to obtain a satisfactory treatment result, the entire fractured area must be treated uniformly with the sound waves. This requires complex movement mechanisms for the pressure pul...
