Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to a kind of gun barrels of ligation device. BACKGROUND
[0002] Ligation surgery (also known as rubber band ligation) is a commonly used non-surgical treatment method, mainly used for the treatment of internal hemorrhoids. This surgery places one or more rubber bands at the base of the hemorrhoids, cutting off the blood supply to the hemorrhoids, causing them to gradually necrose and fall off.
[0003] In traditional ligation surgery, if a larger hemorrhoid is encountered, and the gun barrel end of the ligation device cannot fully accommodate the diseased tissue, the usual solutions are: 1. Replace the gun barrel with a larger inner diameter; 2. Perform ligation in multiple sessions; 3. Use other treatment methods, such as laser therapy or surgical resection. However, these methods have some drawbacks. The use of a larger inner diameter gun barrel can cause discomfort for the patient, and multiple ligation sessions often require waiting for the previously ligated portion to heal before performing the next ligation, requiring multiple treatments for the patient, and using other methods for treatment increases treatment costs. SUMMARY
[0004] The purpose of the present utility model is to provide a gun barrel for a ligation device to solve the technical problems mentioned in the background.
[0005] The technical solution to achieve the purpose of the present utility model is: a gun barrel for a ligation device, comprising a negative pressure tube, a gun head, and an elastic line. The gun head is connected to one end of the negative pressure tube. The negative pressure tube is hollow inside to form a negative pressure channel. The elastic line is arranged along the length of the negative pressure tube on the outside of the negative pressure tube. One end of the elastic line is sleeved around the other end of the gun head. A puncture device is arranged in the gun head.
[0006] Further, the gun head is in the shape of "L", and the puncture device is a puncture cone arranged on the inner wall of the gun head. The tip of the puncture cone is directed towards the opening at the end of the gun head.
[0007] Further, the length of the tip of the puncture cone to the end of the gun head is greater than the radius of the end of the gun head.
[0008] Further, it also includes a half-pipe shell. The half-pipe shell and the negative pressure tube are arranged side by side. The half-pipe shell and the side wall of the negative pressure tube together form an elastic line tube. The elastic line passes through the elastic line tube.
[0009] Further, the half-pipe shell and the negative pressure tube are detachably connected.
[0010] Further, two clamping grooves are arranged on the outer side wall of the negative pressure pipe along the length direction of the negative pressure pipe, and the two sides of the half pipe shell are clamped into the two clamping grooves respectively; one end of the half pipe shell is provided with a fixing part, and a through hole is arranged on the fixing part and used for the negative pressure pipe to pass through.
[0011] Further, a guide groove is arranged on the fixing part.
[0012] Further, a stop block is arranged on one side of the negative pressure pipe, and the stop block is matched with the fixing part.
[0013] Further, a fuse device is arranged in the elastic line pipe.
[0014] By adopting the above technical scheme, the utility model has the following beneficial effects:
[0015] (1) The utility model discloses a puncture device arranged in the gun head, which can puncture the tissue when the diseased tissue is large, so that the tissue is completely adsorbed in the gun head after being reduced, and the large diseased tissue can be once laced and ligated.
[0016] (2) The gun head of the utility model is in the shape of "L", so that the puncture cone can be aligned with the opening at the end of the gun head after being arranged on the inner side wall of the gun head, and compared with the linear gun head, the puncture cone is easier to arrange.
[0017] (3) The length from the tip of the puncture cone to the end of the gun head is greater than the radius of the end of the gun head, so that the small diseased tissue is prevented from being punctured by the puncture cone after being adsorbed in the gun head.
[0018] (4) The half pipe shell and the side wall of the negative pressure pipe jointly form the elastic line pipe, so that the damage of the elastic line to the surrounding healthy tissue is reduced, and the volume of the whole gun barrel is reduced.
[0019] (5) The half pipe shell and the negative pressure pipe are detachably connected, so that the elastic line can be conveniently replaced.
[0020] (6) The end of the negative pressure pipe passes through the through hole on the fixing part, and the two sides of the half pipe shell are clamped into the clamping grooves, so that the assembly of the gun barrel can be conveniently completed.
[0021] (7) The guide groove is arranged on the fixing part, so that the gun barrel can be conveniently installed on the gun body.
[0022] (8) The stop block is arranged on one side of the negative pressure pipe and matched with the fixing part, and the stop block is abutted with the fixing part after installation.
[0023] (9) The fuse device is arranged in the elastic line pipe, so that the elastic line can be conveniently cut off. BRIEF DESCRIPTION OF DRAWINGS
