DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0027] In the present embodiment, the so-called "front" refers to the direction of the muzzle of the gun body, and the so-called "rear" refers to the direction in which the gun body is connected to the negative pressure machine. The terms "front" and "rear" do not have other meanings, but are only used for the convenience of overall description.

[0028] As Figures 1-7 shown, a full-manual hemorrhoid ligation gun with a wrench includes a gun body 1, a negative pressure pipe 3, a dial key connecting block 5, a sliding block 6, a trigger 10, a push rod 11, and a spring 12. The negative pressure pipe 3 is arranged in the gun body 1, and a connecting end head of the negative pressure pipe is arranged outside the gun body 1. The connecting end head is connected to an external negative pressure machine. When in use, a negative pressure is generated by the external negative pressure machine, and a hemorrhoid lesion is adsorbed by the negative pressure. A negative pressure switch 4 is arranged on a gun body shell 101, and the negative pressure switch 4 is connected to a closing valve on the negative pressure pipe 3. The negative pressure switch in the present embodiment is a press button, as shown in Figure 7 , which controls the opening and closing of the negative pressure pipe in a manual manner.

[0029] The front end of the gun body 1 is connected to the quick-release sleeve assembly 2. This quick-release sleeve assembly can have various structural forms, but it needs to meet basic functions. Therefore, in this embodiment, combined with the attached... Figure 6 and 7 The quick-release ligation tube assembly 2 used in this embodiment includes an outer tube 21, an inner tube 22, and a rotary cutting connecting tube 14. The outer tube 21 is fitted onto the inner tube 22, and the front end of the inner tube 22 extends out of the outer tube 21. The opening of the ligation ring is fixed to the inner tube 22 extending out of the outer tube. The function of the ligation ring is to cover the hemorrhoid lesion. The rear end of the inner tube 22 is connected to the gun body 1 by a quick-release head 23, which allows for quick disassembly and replacement.

[0030] Combination Figure 7 As shown, a groove 701 is provided on the outer shell 101 of the gun body 1. The groove is a long strip structure, and a sliding switch 7 is provided on the groove 701. The sliding switch can slide within the groove. Figure 3 As shown, the toggle switch connecting block 5 is a structure specifically designed to connect the sliding switch and the slider. The structure is functionally designed and mainly consists of two ends: an actuating end and a locking end. The sliding switch 7 is connected to the actuating end 501 of the toggle switch connecting block 5. A row of dials 8 is provided on the inner wall of the gun body shell 101. The actuating end 501 of the toggle switch connecting block 5 engages with the dials 8. During use, the sliding switch slides in the groove, inevitably driving the actuating end of the toggle switch connecting block. The dials can fix the trajectory of the actuating end, preventing movement deviation. In specific use, the positions of the groove and the dials need to correspond. The locking end 502 of the toggle switch connecting block 5 is connected to the rear end of the slider 6. The slider 6 is slidably locked onto the negative pressure pipe 3, combined with... Figure 4 As shown, the slider is also a special structure designed to enable free sliding at the lateral end of the negative pressure tube. Its main function is to slide along the negative pressure tube. The front end of the slider 6 contacts the outer tube 2 of the quick-release sleeve assembly 2.

[0031] In use: Slide the sliding switch, and the toggle connecting block will start moving along the dial. Push the sliding switch forward, and the toggle connecting block will move forward, causing the slider to move towards the front end of the negative pressure tube. The front end of the slider will then contact the outer tube 2. Continuing to move forward will push the outer tube 2. Since the outer tube 2 is fitted onto the inner tube, and the inner tube is fixedly connected to the gun body, as the outer tube continues to move forward while the inner tube remains stationary, the ligating ring fitted at the front end of the inner tube will be pushed out by the outer tube. The inner tube will then adhere to the hemorrhoid lesion, and the pushed-out ligating ring will be attached to the hemorrhoid lesion.

[0032] The other side wrench works similarly to the principle of a pistol, the wrench 10 is fixed with the gun body 1 through a bolt, the part of the gun body 1 where the wrench is located is the wrench part, and the part of the gun body 1 where the wrench is located is the movable part. When the wrench part is pulled by hand, the movable part can be driven to move up and down. The movable part is normally at a certain distance from the push rod, and the two do not contact or slightly contact. When the wrench part moves downward, the wrench part gives the push rod a force. Because the push rod is transversely arranged and parallel to the horizontal rod part of the negative pressure pipe, the force given by the wrench part makes the trigger 10 drive the push rod 11 to move forward, and the front end 112 of the push rod 11 is connected with the rotary cutting connection pipe 14 of the quick release sleeve ligation pipe assembly 2, so that the push rod can drive the rotary cutting connection pipe 14 to move forward. Figure 5

[0033] The push rod 11 and the rotary cutting connection pipe 14 are connected through the connecting block 13. Specifically, the spring 12 is arranged on the front end 112 of the push rod 11, the middle part of the push rod 11 is provided with a ring, one end of the spring 12 is arranged on the ring, and the other end is arranged on the rear end of the connecting block 13. The front end of the connecting block 13 is fixed with the rotary cutting connection pipe 14. Moreover, the rotary cutting connection pipe 14 is clamped on the outer pipe 21, and is not a fixed structure. Therefore, when the rotary cutting connection pipe moves forward under the action of the push rod, the front end of the rotary cutting connection pipe 14 is provided with a rotary cutting pipe 15, and the front end of the rotary cutting pipe 15 is a knife edge. The knife edge can cut the sleeve ligation ring arranged in front of the rotary cutting pipe 15 to cut off the sleeve ligation ring. After the sleeve ligation ring that has been ligation on the hemorrhoid lesion is cut off, it remains in the lesion until the lesion is necrotic and the volume is small and falls off.

[0034] The above only describes the preferred embodiment of the present application, and does not limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.​
