At this time, a device is connected through the drainage outlet 220F to form a negative pressure, so that the material to be sucked at the lesion enters the drainage channel 102 through the drainage inlet 1020, and is then discharged out of the body through the drainage outlet 220F. .

As shown in FIG. 11C , when the injection-discharge control valve 62F is operated to change the communication direction of the conversion member 62F, so that the valve assembly 60F is in a liquid injection working state, the conversion member 61F switches the injection channel 101 communicates with the liquid injection inlet 210F, that is, the liquid injection inlet 210F communicates with the liquid injection channel 101 through the conversion member 62F. At this time, the liquid is injected into the liquid injection channel 101 through the liquid injection inlet 210F, and then injected into the lesion site through the liquid injection outlet 1010 .

By adjusting the injection and discharge control valve 62F, the attractable laser endoscopic surgical instrument can be switched at any time between the three working states of liquid injection, liquid discharge and simultaneous liquid injection and discharge, which can make liquid injection, The liquid drainage can be performed independently, alternately, or simultaneously, which simplifies the complexity of the instrument operation and can meet the application requirements of various occasions. In addition, it can be operated with one hand, which is more user-friendly, simple and convenient.
