[0019] See also Figures 1 to 3 A barrel assembly of a ligation device includes a gun body 1 of the ligation device, and the gun body 1 is detachably connected to the barrel assembly. The gun body 1 has a gun handle at the rear end, and a firing wheel is arranged in the gun handle, and other structures of the ligation device are conventional components in the art, which will not be described here.

[0020] The barrel assembly includes a barrel 2. The barrel 2 includes a long tube portion 21 and a connecting portion 22. The outer diameter of the connecting portion 22 is larger than the outer diameter of the long tube portion 21, and the inner diameter of the connecting portion 22 is larger than the inner diameter of the long tube portion 21. The inner side of the connecting portion 22 is butted against the gun body 1. The rear end of the barrel 2 is sleeved with a knob 4, which is sleeved on the outer side of the connecting portion 22. After the knob 4 is sleeved on the outer side of the connecting portion 22, the connecting portion 22 is butted against the gun body 1, so that the barrel 2 and the gun body 1 can rotate relative to each other, thereby realizing the installation of the gun body 1, and the barrel 2 can be rotated on the gun body 1 by rotating the knob 4.

[0021] The front end of the gun barrel 2 is sleeved with a gun barrel mouth 3. The front end of the gun barrel mouth 3 has a bending opening 31 inclined with respect to the horizontal direction. The rear end of the gun barrel mouth 3 has a connecting opening 32 connected with the gun barrel 2, and the connecting opening 32 is arranged horizontally. The connecting opening 32 is butted with the long tube part 21, so that the bending opening 31 as the adsorption tissue is inclined with respect to the gun body 1 in the horizontal direction, and the bending opening 31 with a certain inclination angle can better adsorb tissue.

[0022] The knob 4 has a marking portion 41 pointing to the bending direction of the bending opening 31. The barrel 2 and the barrel mouth 3 are rotated synchronously by turning the knob 4, thereby adjusting the direction of the barrel mouth 3. The direction of the bending opening 31 can be clearly determined according to the position of the marking portion 41, so as to better adjust the adsorption position and improve the surgical effect.

[0023] The barrel mouth 3 is covered with a rubber ring 5, which is connected to the rotating wheel of the gun body 1 through a firing line 6. A guide tube is also provided on the outside of the barrel 2, and the firing line is connected to the rotating wheel along the guide tube. The firing line 6 passes through the guide tube and is connected to the rotating wheel, and the rubber ring 5 on the barrel mouth 3 is fired by rotating. The guide tube can prevent the firing line from being entangled when the gun body 1 rotates, ensuring that the operation can be carried out normally.

[0024] Different from the prior art, the barrel assembly of the ligation device of the utility model can position the knob corresponding to the barrel mouth, which is convenient for adjusting the position of the barrel mouth. The barrel mouth with a bent mouth can better absorb tissue, and the surgical effect is good.

[0025] 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.
