[0025] Working principle: The cutting tool is connected to the front end of the handle housing 18, and the core connector 29 is connected to the external power system host. Pressing different button caps 4 on the handle housing 18 causes the lower hand control board 9 to generate different electrical signals. The hand control board 9 outputs different electrical signals to control the motor 20 to rotate forward, backward and reciprocating. The motor 20 drives the front cutting tool to rotate. The handle housing 18 has a water channel. When the water pipe connector 19 is connected to the external negative pressure device, the removed tissue and waste liquid are sucked out along the water channel and water pipe connector 19. By turning the valve roller 13 on the handle housing 18, the valve rocker arm 11 is rotated back and forth, thereby rotating the valve spindle 14, thus controlling the normally open and closed water channel.
