[0017] The technical scheme in the embodiment of the utility model will be described clearly and completely below. The structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification, so that people familiar with this technology can understand and read them, and are not used to limit the limiting conditions that can be implemented in the utility model, so they have no substantial technical significance. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effect that can be produced by the utility model and the purpose that can be achieved, should still fall within the scope that the technical content disclosed in the utility model can cover. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and so on quoted in this specification are only for the convenience of narration, and are not used to limit the scope that can be implemented. The change or adjustment of the relative relationship, without substantial change of the technical content, should also be regarded as the scope that can be implemented in the utility model.

[0018] See also Figures 1 to 3A quick-change ligature assembly includes a gun body 1 of the ligature assembly, a barrel assembly 2 is detachably connected to the gun body 1, and the barrel assembly 2 and the gun body 1 are split. When the ligature assembly fails, it can be quickly replaced to avoid affecting the surgical process. The gun body 1 has a firing assembly, and the rubber ring on the barrel assembly 2 is connected to the firing assembly through a firing line. The gun body 1 can adopt a conventional structure of the ligature assembly, which will not be described here.

[0019] The front end of the gun body 1 has a locking column 3, which is a cylindrical structure and is fixedly installed in the gun body 1. The locking column 3 has a connecting through hole 31, and the front end of the locking column 3 has a limiting groove 32. The rear end of the barrel assembly 2 has a mounting column 21, and the mounting column 21 has a limiting block 22, and the number of the limiting block 22 and the limiting groove 32 is 2. The mounting column 21 is inserted into the connecting through hole 31 to connect the barrel assembly 2 with the locking column 3, and the limiting block 22 is engaged with the limiting groove 32 to fix the axial position of the gun body 1.

[0020] The limiting groove 32 is axially arranged along the surface of the locking column 3 and is L-shaped. The limiting block 22 protrudes along the radial direction of the mounting column 21. The limiting block 22 enters from the front end of the limiting groove 32 and then rotates to engage with the rear end of the limiting groove 32. When the barrel assembly 2 is installed, the limiting block 22 is inserted into the locking groove along the axial direction. When the limiting block 22 moves to the bottom of the locking groove, the barrel assembly 2 is rotated to engage the limiting block 22 with the end of the locking groove, thereby realizing the rapid installation of the barrel assembly. When dismantling, the barrel assembly 2 is rotated and then pulled out. The disassembly and assembly structure is simple and the operation is convenient. No professional training is required and the operation can be quickly adapted.

[0021] The front end of the gun barrel assembly 2 is sleeved with a rubber ring, and the gun barrel assembly 2 is replaced from the locking column 3 to quickly replace the rubber ring used for surgery. The fundamental purpose of adopting the replaceable gun barrel assembly 2 is to achieve the rapid replacement of the rubber ring. Before the operation, multiple gun barrel assemblies 2 can be prepared. After the rubber ring of one gun barrel assembly 2 is used up, the next assembly with the rubber ring installed is immediately replaced to quickly implement the ligation of the next hemorrhoid. Or after the nurse replaces the rubber ring, the new rubber ring is installed on the first gun barrel assembly 2 to prepare for the next ligation. The gun barrel assembly 2 is directly replaced or replaced according to the actual situation for the operator to choose, which can quickly realize the replacement of the assembly, shorten the hemorrhoid operation time, and reduce the pain of the patient.

[0022] Different from the prior art, the utility model has a quick-change ligation device, which can realize the rapid replacement of rubber rings through a detachable gun body, thus shortening the ligation preparation time, improving the operation efficiency and reducing the pain of patients.

[0023] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
