Abstract: PURPOSE:To safety and certainly suck and remove only a hematoma by identify the boundary of the hematoma and normal tissue, by providing a color detection means inserted through a hollow sheath to make it possible to discriminate between the hematoma and the normal tissue. CONSTITUTION:A vibration member 48 is allowed to protrude from the leading end part of a sheath 2 and the leading end part thereof is brought into contact with a hematoma 49. When the boundary of the hematoma 49 and normal tissue comes near, the red component contained in the reflected light incident to a light receiving fiber 56 becomes weak and white becomes strong. Therefore, the output level of a color sensor 62 becomes low and the voltage level of the AC component formed in a power supply control circuit 64 becomes low. When the voltage level becomes low, the power supply control circuit 64 stops the operation of a drive circuit 67 to terminate the vibration of the vibration member 48. By this method, the boundary ot the hematoma 49 and the normal tissue can be identified and, since the vibration of the vibration member 48 can be stopped when the vibration member 48 approaches the normal tissue, only the tematoma can be sucked and removed safely and certainly.
