A valve housing 234 is also provided. The valve housing 234 may be integrally formed with the body of the second hand piece 22 or may be subsequently mounted or attached to the body of the second hand piece 22.

The valve button 231 is arranged to be switchable between an open position and a depressed position, in which the valve plate 233 closes the second suction tube hole 221 at the second hand-held segment; in the open position, the valve plate 233 shields the second suction tube hole 221 at the second hand-held segment.

The compression spring 232 applies an elastic force perpendicular to the extending direction of the body of the second hand-held segment 22 to the valve button 231, and elastically holds the valve button 231 and the valve plate 233 in the open position. Specifically, in fig. 3, the compression spring 232 applies an upward force to the valve button 231. When the second suction pipe hole 221 needs to be cut off, the valve button 231 is pressed along the downward direction in fig. 3, the elastic force of the pressure spring 232 is overcome, so that the valve button 231 moves downward, the valve plate 233 is driven to move downward, and the valve plate 233 shields the second suction pipe hole 221 at the second handheld section. After releasing the button, the valve button 231 and the valve plate 233 are automatically retracted to the open position under the action of the spring.

Thus, a quick and convenient cut-off of suction or negative pressure is achieved, and the suction is stopped quickly in case of emergency.

Through the design of manual control valve, alright when getting away the aspirator tip or changing and attracting the wound department, press the button through thumb or other fingers and accomplish the shutoff effect to the inside suction of aspirator tip body, avoid aspirator tip because the suction from taking adsorbs on blood vessel or nerve surface and cause the tissue damage problem.
