Embodiment Construction

[0048] By coupling a ballistically generated pressure wave in the form of a diffuse shock wave into biological tissue via the transfer element 2 (which is blunt at the body contact surface), the medical device allows the treatment of biological hard and soft tissues, especially for Treatment for healing skeletal disorders such as fractures, extremities, tendonitis, and periodontitis, and for pain management in the soft tissue areas of the musculoskeletal system near the bone.

[0049] The handheld device is formed by a housing 4 housing a pressure chamber 6 in which an impact member 10 is reciprocated between two end positions by means of a pneumatic drive 14 combined with a back pressure chamber 8 . The pressure groove 6 is surrounded, for example, in a coaxial annular manner. For pneumatic drive, the length of the acceleration channel is about 100-250mm.

[0050] In a proximal position of the impact member 10 , a magnetic holder and / or a possibly elastic stop element 27 may...

Abstract

The invention relates to an instrument for treating biological tissue, comprising a housing (4), in which is disposed a ballistic device for generating extracorporeal shock wave-like pressure waves and a transfer element (2) permanently placed on the biological tissue, said element coupling the pressure waves into the body of living creatures, wherein the transfer element (2) couples non-focused, ballistically generated, shock wave-like pressure waves into the biological tissue, said waves generated by an impaction part (10) that is accelerated to a high final velocity of over 5 m/s by a pneumatic medium which is under an operating pressure in a pressure channel (6), said impaction part moving back and forth and impinging on the transfer element (2), wherein the front part of the pressure channel (6) is connected to a back-pressure chamber (8) into which the pneumatic medium, which is located distally in front of the impaction part (10), can flow in toward the transfer element (2) upon acceleration of the impaction part (10). A fast-acting valve (16) releases the pneumatic medium, which is under operating pressure, into the pressure channel (6), wherein a control circuit (17) controls the duration of opening of the valve (16) as a function of at least one or a combination of the following parameters: working pressure, impact frequency or pressure in the back-pressure chamber (8).

Description

Technical field [0001] The invention relates to an instrument for treating biological tissue, as defined in the preamble of claim 1 or 2, and to an instrument for generating shock waves within such an instrument, as defined in the preamble of claim 14 or 15. shaped pressure wave method. Background technique [0002] Such a device is known from WO9857707 and utilizes shock wave-like radiating pressure waves to accelerate the healing process of fractures, enthesiopathies, tendonitis and is also used to accelerate the healing process of periodontitis. Another area of ​​application is the treatment of pain within the soft tissue area of ​​the musculoskeletal system near the bones. [0003] Other known pressure pulse sources used for the same therapeutic purposes use focused shock waves and are only effective within a very limited focused zone. However, in order to obtain satisfactory treatment results, the entire fracture area must be treated uniformly with sound waves. This ...
