The lower end of the outer cone sleeve 402 is provided with an inner cone, and the lower end of the inner cone rod 403 is provided with an outer cone. The elastic force of the sealing compression spring 405 can drive the inner cone rod 403 to move upward so that the outer cone is embedded in the inner cone to achieve sealing. The outer diameter of the inner cone rod 403 is smaller than the inner hole size of the outer cone sleeve 402, so there is a gap. When the cap 404 is pressed down by hand, the inner cone rod 403 overcomes the downward movement of the sealing compression spring 405. At this time, the internal and external air can flow through the gap between the outer cone sleeve 402 and the inner cone rod 403. The upper part of the outer shell 401 is threadedly connected to the outer cone sleeve 402, and the inner cone rod 403 is slidably connected to the inner cone sleeve 402. A pressure cap 404 is installed on the top, and a sealing compression spring 405 is sleeved on the inner cone rod 403 between the pressure cap 404 and the outer cone sliding sleeve 402. A firing handle 5 is hinged at the bottom of the shell 401, and a push rod 6 is hinged at the upper end of the firing handle 5. A double-ring buckle 7 close to the firing handle 5 is installed between the stainless steel air pipe 1 and the push rod 6.

The elastic force of the reset compression spring 8 can push the push rod 6 to move upward. When the firing handle 5 is pressed upward by hand, the push rod 6 can overcome the elastic force of the reset compression spring 8 and move downward. A detachable sleeve ligation assembly 9 is installed at the lower end of the stainless steel air pipe 1 and the end of the push rod 6. The sleeve ligation assembly 9 includes an inner suction sleeve 901 and a sealing ring 902. The outer surface of the inner suction sleeve 901 is sleeved with an outer push sleeve 903 and a ligation ring 904. The inner suction sleeve 901 includes a front suction cavity 9011 and a rear threaded hole 9012. The lower end of the stainless steel air pipe 1 is provided with an external thread 102.

In this process, the push rod 6 overcomes the elastic force of the return compression spring 8 and pushes forward. At the same time, the outer push sleeve 903 also moves forward through the thrust of the push rod 6, and then the tying ring 904 at the front end of the inner suction sleeve 901 is pushed down and pierces the root of the hemorrhoids. The system vacuum is further cut off and the thumb presses the cap 404 downwards. At this time, the inner cone rod 403 overcomes the elastic force of the sealing compression spring 405 and moves downwards, and then the tapered sealing structure is opened so that it is not The interior of the stainless steel trachea 1 is connected to the outside air through the gap between the outer cone sliding sleeve 402 and the inner cone rod 403, and further air is sucked into the stainless steel trachea 1 to balance the internal and external air pressures. At this time, the hemorrhoids are no longer affected by the suction force of the inner suction sleeve 901 and can be easily detached. The ligation ring 904 is further re-put on the front end of the inner suction sleeve 901 to prepare for the next operation. After the operation is completed, the semicircular buckle 9031 is removed from the front end of the push rod 6, and the entire ligation assembly 9 is further removed and discarded. The remaining parts are disinfected and prepared for the next use because they do not contact the patient.

[0024] To sum up, the conical sealing and snap-fit ​​device of the ligation device makes the ligation assembly 9 that is in direct contact with the patient into a detachable form, that is, the inner suction sleeve 901 of the ligation assembly 9 is detachably connected to the stainless steel trachea 1 through a threaded connection, and the outer push sleeve 903 of the ligation assembly 9 is also detachably connected to the push rod 6 through a semicircular buckle 9031. Therefore, during use, only the ligation assembly 9 needs to be replaced, thereby achieving the effect of reducing costs and saving resources. The interior of the conical sealing and pressure relief device 4 uses the inner cone and outer cone that fit into each other as a sealing structure. Since the conical sealing structure has a large sealing area and thus a good sealing effect, since the conical sealing and pressure relief device 4 is installed on the stainless steel trachea 1 above the cavity handle 2, the cavity handle 2 can be grasped with one hand while the thumb can also press the conical sealing and pressure relief device 4, so it is easy to operate.
