DETAILED DESCRIPTION
[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0022] As Figure 1 , Figure 2 As shown in the figure, a cutting device of a hemorrhoid ligator includes a rotary cutter 5 and a mounting base 1. The rotary cutter 5 is a cylindrical structure, and the front end of the rotary cutter 5 is a circular knife edge 51. The rotary cutter is cylindrical, and a certain force is given to the rotary cutter through the mounting base, so that the ligation ring can be cut.
[0023] Here, the rotary cutter can be selected from the following two types:
[0024] As shown in the figure, Figure 3 and Figure 4 the knife edge 51 is integrally formed with the rotary cutter. The integrally formed knife edge is not easy to break, but after being used for a period of time, the knife edge part is not sharp enough to cut the ligation ring, and the entire rotary cutter needs to be discarded.
[0025] As shown in the figure, Figure 5 a breakable groove 52 is arranged at the connection between the knife edge and the rotary cutter. This is similar to the principle of a blade of a stationery knife. A breakable groove is designed in advance. When the knife edge is used for many times and becomes dull, it can be broken by gently breaking, without the need to discard the entire rotary cutter. In this way, the generation of such medical waste can be reduced.
[0026] The front end of the mounting base 1 is provided with a knife edge mounting block 10, and the knife edge mounting block 10 is provided with a mounting hole 6. When the rear end of the rotary cutter 5 is inserted into the mounting hole 6, the rotary cutter is clamped and fixed with the mounting base 1. The cylindrical structure of the rotary cutter is very convenient for clamping into the mounting hole, and the installation and replacement are very convenient.
[0027] The rear end of the mounting base 1 is provided with a connecting block 2, and the connecting block 2 is provided with a connecting buckle 3. The connecting buckle 3 is detachably connected with an external hemorrhoid ligator gun body through a connecting block 4. The mounting base 1 includes an arc-shaped shell 9, and the arc-shaped shell 9 is provided with a long strip-shaped hollow observation hole 8. The arc-shaped shell 9 corresponds to the curvature of the external pipe of the gun mouth of the external hemorrhoid ligator. The arc-shaped shell structure is used to fit with the external pipe of the gun mouth of the hemorrhoid ligator gun. The fitting is a light clamping fitting. The arc-shaped shell can be attached or detached by force. Through the two structures, the rotary cutter can be fixed in position.
[0028] The inner wall of the hollow observation hole 8 is provided with a positioning groove 7, and the positioning groove 7 is a semicircular arc structure. The central axis direction of the rotary cutter cylinder coincides with the central axis direction of the arc-shaped shell. The positioning groove also has a positioning function. When used, the external pipe of the gun mouth of the hemorrhoid ligator gun is provided with a corresponding convex point. In this way, it can be determined whether the entire mounting base is in place in the position of the external pipe of the gun mouth of the hemorrhoid ligator gun. The hollow observation hole 8 and the positioning groove 7 are used to ensure that the rotary cutter is always in the correct position, so as to prevent deviation and enable the rotary cutter to cut the ligation ring with force.
[0029] The connecting block 2 protrudes in an arc shape, and the protruding part of the connecting block 2 is a square notch structure. The design of the connecting block is to facilitate hand holding, and the whole mounting base can be held when the whole rotary cutter is pushed forward.
[0030] In use, the connecting block is used in combination with a ligature device, and the mounting base is pushed forward and backward to cut the ligature ring or elastic line through the blade of the rotary cutter at the front end. Because the whole rotary cutter is fixed on a straight line, the ligature device is very stable, convenient and easy to use when cutting the ligature ring.
[0031] The above merely describes the preferred embodiments of the present application and is not intended to 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.
