[0049] The ligating rod 2 is cylindrical, and a groove is provided at the rear end of the ligating rod 2. The groove is inserted into the outer wall of the ligating rod 2. The ligating rod 2 is set at the bottom of the base 18. The front end of the ligating elastic line 17 is spaced out and fitted at the staggered step at the front end of the push tube 1. The rear end of the ligating elastic line 17 is respectively set inside the ligating rod 2 and is locked in the groove.

[0050] In this embodiment, the ligation triggering component is disposed inside the housing. One end of the ligation triggering component is connected to the continuous ligation component, and the other end is connected to the negative pressure pipeline component. The negative pressure pipeline component extends to the outside of the housing and is connected to the negative pressure gas source.

[0051] Specifically, the ligation triggering assembly includes a cavity connecting tube 7, a reset tube 19, a reset spring 6, and a trigger 11.

[0052] The cavity connecting tube 7 includes a base column and an extension tube. The diameter of the extension tube is smaller than the diameter of the base column, and the diameter of the extension tube is smaller than the diameter of the connecting column 5 and the connecting spring. The extension tube is integrally set on the end face of the base column. The base column is a hollow structure. The diameter of the extension tube is the same as the diameter of the rear end face of the suction cavity tube 3. The base column is installed in the cavity connecting tube mounting groove 26. The end of the extension tube away from the base column passes through the connecting column 5 and the connecting spring and abuts against the rear end face of the suction cavity tube 3.

[0053] like Figure 5 As shown, the reset tube 19 has a cylindrical structure with two symmetrical reset holes on the side wall of the cylinder. The guide plate 21 inside the outer shell is located in the reset hole. An annular boss is provided at the rear end of the cylinder, and two protrusions are symmetrically arranged on the annular boss. The protrusions are located in the guide groove 24 inside the outer shell. The outer diameter of the front end of the reset tube 19 is the same as the inner diameter of the connecting post 5.

The lower part of the trigger 11 is installed in the trigger installation slot 25, and the lower end of the trigger 11 extends to the outside of the shell. The trigger 11 is pulled to drive the reset pipe 19 to move horizontally forward along the guide plate 21 and the guide slot 24 and press the reset spring 6. The reset pipe 19 pushes the connecting column 5 and the push pipe 1 to move forward. Since the suction cavity pipe 3 is stationary, the push pipe 1 pushes the push pipe 1 and the suction cavity pipe 3 to disengage the elastic loop 17 at the step of the front end of the suction cavity pipe 3. The reset spring 6 drives the reset pipe 19 to move horizontally backward along the guide plate 21 and the guide slot 24 due to the elastic force, so that the reset pipe 19 drives the connecting column 5 and the push pipe 1 to reset backward. The trigger 11 is pulled repeatedly to make the three elastic loops 17 disengage in turn.

[0055] In the embodiment, the disengaging assembly is arranged through the shell and at the rear end of the looped rod 2.

The rotating shaft is provided with a positioning hole and three shift blocks.

[0057] The three shift blocks are distributed in a staggered manner and surround the rotating shaft for one turn. Each shift block is arranged corresponding to the looped rod 2. When the rotating shaft rotates by one third, one looped rod 2 can be disengaged. When the rotating shaft rotates by one turn, three looped rods 2 can be disengaged in turn.

[0058] The trigger switch 14 comprises a knob, a rotating rod and a trigger plate. The knob is integrally arranged on one side of the trigger plate. The rotating rod is integrally arranged on the other side of the trigger plate. A limiting block is integrally arranged on the rotating rod. The limiting block is made of rubber. The limiting block is arranged corresponding to the positioning hole. The trigger plate is installed in the trigger switch installation slot on the outside of the left end cover 16. The knob is located on the outside of the shell. The rotating rod is arranged through the trigger switch installation slot, the rotating shaft and the limiting hole 23 on the right end cover 8 in sequence. The limiting block is located in the positioning hole of the rotating shaft. Therefore, the rotating trigger switch 14 can drive the rotating shaft to rotate. A triangular mark is arranged on the trigger plate. An inverted triangular mark corresponding to the triangular mark is arranged on the outside of the left end cover 16. The rotating position of the trigger switch 14 for disengaging the looped rod 2 can be clearly determined. Therefore, the number of disengaged looped rods 2 can be clearly controlled by continuously rotating the trigger switch 14.

[0059] In the embodiment, the negative pressure switch 15 is installed in the negative pressure switch installation slot on the outside of the upper end cover 16. The negative pressure switch 15 is used to control the negative pressure pipe assembly. The negative pressure switch 15 is a toggle switch.

[0060] The negative pressure pipeline assembly is connected to the suction cavity pipe 3 through the cavity connection pipe 7. The negative pressure pipeline assembly includes a three-way pipe 12 and a negative pressure connector 13. One end of the three-way pipe 12 is connected to the cavity connection pipe 7 through a hose 9, and the other end is connected to the negative pressure connector 13 through a hose 9. The negative pressure connector 13 extends to the outside of the outer shell to connect to the negative pressure air source.

[0061] In this embodiment, the negative pressure connector 13, the three-way pipe 12, the cavity connecting pipe 7, and the suction cavity pipe 3 are connected in a continuous manner.

[0062] The usage process in this embodiment is as follows:

[0063] The negative pressure connector 13 is connected to the negative pressure. The negative pressure switch 15 is activated, and the tissue is aspirated through the suction cavity tube 3. Then, the trigger 11 is pulled to push the push tube 1 so that the ligating elastic wire 17 is dislodged and the tissue is ligated. Then, the trigger switch 14 is rotated so that the toggle on the rotating shaft moves the ligating rod 2, so that the ligating rod 2 is dislodged from the locking groove. Then, the tissue is operated through the ligating rod 2. When ligating new tissue, the trigger 11 is pulled and the trigger switch 14 is rotated in sequence until all three ligating rods 2 are dislodged. After all the ligating rods 2 are completely dislodged, when continuing to ligate, the buckle 4 is pressed to pull the continuous ligating assembly out of the shell, and then another continuous ligating assembly is inserted into the shell.
