In this embodiment, the optical fiber control end 23F is detachably mounted to the suction tube 10 through an optical fiber connection portion 232F, and is adjusted through the optical fiber control valve 231F to control the operation of the optical fiber 30, similar to the above-described embodiments.

In this embodiment, the control body 24F includes an integration element 241F, wherein the integration element 241F is disposed at a suitable position of the control body 24F and is close to the holding portion of the control body 24F, so that the integration element 241F can be operated by one hand when the medical staff holds the control body 24F.

The control portion 24F includes a valve assembly 60F, wherein the valve assembly 60F is mounted to the manifold 241F. The liquid injection control end 21F and the liquid discharge control end 22F are mounted on the manifold 241F and communicate with the valve assembly 60F.

Specifically, the valve assembly 60F includes a switching member 61F and a drainage control valve 62F, wherein the switching member 61F is installed inside the manifold 241F and is switchably connected to the fluid injection channel 101 and the fluid discharge channel 102, and the drainage control valve 62F is connected to the switching member 61F and is installed on the top of the manifold 241F for the convenience of the medical staff.

The liquid injection control end 21F and the liquid discharge control end 22F respectively have a liquid injection inlet 210F and a liquid discharge outlet 220F, and the liquid injection inlet 210F and the liquid discharge inlet 220F are respectively communicated with the converting member 61F and are respectively communicated with the liquid injection channel 101 and the liquid discharge channel 102 through the converting member 61F.

The injection and drainage control valve 62F controls the communication direction of the converting element 61F, so that the converting element 61F selectively communicates with the injection channel 101 and the injection inlet 210F, respectively, or communicates with the drainage channel 102 and the drainage outlet 220F, or communicates with the injection channel 101, the injection inlet 210F, the drainage channel 102 and the drainage outlet 220F simultaneously.

That is, the injection/drainage control valve 62F allows the attractable endoscopic laser surgical instrument to have three operating states, namely, an injection operating state in which only an injection operation is performed, a drainage operating state in which only a drainage operation is performed, and an injection/drainage operating state in which both injection and drainage operations are performed.

In other words, the switching member 61F changes the communication direction of the switching member 61F under the control of the injection/discharge control valve 62F, for example:

as shown in fig. 11A, when the fluid injection control valve 62F is operated to change the communication direction of the switching member 62F, so that the valve assembly 60F is in the fluid injection operating state, the switching member 61F simultaneously and independently communicates with the fluid injection channel 101 and the fluid discharge channel 102, i.e., the fluid injection inlet 210F communicates with the fluid injection channel 101 through the switching member 62F, and the fluid discharge outlet 220F communicates with the fluid discharge channel 102 through the switching member 62F. At this time, the attractable endoscopic laser surgical instrument can simultaneously perform the injection and drainage operations.

As shown in fig. 11B, when the switching member 62F is operated to change the communication direction of the switching member 62F so that the valve assembly 60F is in the drainage operation state, the switching member 61F communicates the drainage channel 102 with the drainage outlet 220F, i.e., the drainage outlet 220F communicates with the drainage channel 102 via the switching member 62F. At this time, an instrument is connected to the drainage outlet 220F to form a negative pressure, so that the substance to be sucked at the lesion site enters the drainage channel 102 through the drainage inlet 1020 and is discharged to the outside of the body through the drainage outlet 220F.

As shown in fig. 11C, when the switching member 62F is operated to change the communication direction of the switching member 62F, so that the valve assembly 60F is in the liquid filling operation state, the switching member 61F communicates the liquid filling channel 101 with the liquid filling inlet 210F, that is, the liquid filling inlet 210F communicates with the liquid filling channel 101 through the switching 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.

Through adjusting annotate drainage control valve 62F makes attractable for laser laparoscopic surgery instrument switch at any time between three kinds of operating condition of annotating liquid, flowing back and annotating liquid flowing back simultaneously, can make annotate liquid, flowing back and independently go on, also can go on in turn, can also go on simultaneously, simplified the complexity of apparatus operation, can satisfy the application demand of multiple occasion. In addition, the operation can be carried out by one hand, so that the method is more humanized, simple and convenient.
