SHOCKWAVE APPLICATOR AND A SHOCKWAVE APPLICATION SYSTEM

摘要

A shockwave applicator (15), especially for clinical use in oncology, that comprises a first electrode (1) having the shape of a hollow cylinder, which is covered with a porous insulating layer (3) on its outer surface. The first electrode (1) is surrounded by a second electrode (2) of a reflector shape. Between the first electrode (1) and the second electrode (2) a high-voltage impulse source (6) and an isolator (4) are arranged. The space between the electrodes (1, 2) is filled with liquid (11) with defined conductivity. In the hollow space inside the first electrode (1) an ultrasonic probe (5) is mounted in a sliding way. The ultrasonic probe (5) has a defined end position inside the first electrode (1) defined by a stop (7) and the cavity inside the first electrode (1) is protected from liquid (11) penetration with a membrane (8) of an acoustically transparent material. A shockwave application system, especially for clinical use in oncology, comprising a bed (12) for placing the patient, where the patient surface of the bed is fitted with an opening (13) under which the shockwave applicator (15) according to the invention is attached in a liquid-proof and adjustable manner.
