Abstract
The instrument is used along with a cutting tool (1) and a rotary suction pump (2). The instrument has a housing (3) to be held in the hand of an operator having a suction channel (4) forming working and suction openings (5). The pump is located in the channel on an axle (100), as is the cutting tool, which is located near the suction opening. The cutting tool is rigidly connected to the shaft of the pump. The instrument also has an infusion channel (7) which forms an infusion opening (8) at the front side of the housing near the suction opening and contains an infusion pump (9). A flow meter, a pressure-maintaining valve and a speed control device for the pumps are also encompassed in the instrument. ADVANTAGE - The instrument is minimally invasive, and water hammer and other pressure fluctuations are prevented.
