[0002] In today's society, hemorrhoids are a common anorectal disease, which is characterized by lesions and swelling at the end of the rectum. Traditional hemorrhoid surgery is performed by doctors with bare hands or with the help of simple instruments, which is time-consuming, laborious, and prone to bleeding and pain. In order to alleviate the risks and pain caused by surgery, people have developed hemorrhoid ligation devices, which use elastic wire ligation to tighten the root of the hemorrhoids, causing the lesion to necrotize and eventually fall off and heal.

[0003] Among them, it was found through searching that the patent application number CN202223479394.2 discloses a hemorrhoid ligation stapler, including: a gun head, a gun barrel, a gun handle, a trigger and a gun barrel sleeve, one end of the gun barrel is detachably connected to the gun handle, the gun head sleeve is arranged on the other end of the gun barrel, a negative pressure inner tube is arranged inside the gun handle, one end of the negative pressure inner tube is arranged near the gun barrel, the other end of the negative pressure inner tube is arranged through the bottom of the gun handle, a tension wheel is rotatably connected to the upper part of the gun handle, one end of the gun barrel sleeve is sleeved on the gun barrel, the other end of the gun barrel sleeve is embedded in the gun handle, one end of the trigger is embedded in the gun handle and hinged to the gun barrel sleeve, and a blade is arranged on the end of the gun barrel sleeve near the gun head;

[0004] When this structure is in use, a blade is arranged on the barrel sleeve, and the elastic line can be removed by one-hand operation. However, when this structure is in use, it is not easy to put the elastic line on the affected area and it is not easy to tighten it, resulting in insufficient precision in tightening the root of the hemorrhoids.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] As attached Figure 1-4 The disposable electric multi-ring ligation stapler shown in the figure uses the ligation assembly provided on the stapler body 1, and aligns the ligation tube 5 with the tissue to be ligated. The negative pressure switch 11 is turned on to start the negative pressure pump 8. The negative pressure pump 8 extracts the airflow through the conduit 14 during operation, so that negative pressure is formed at the ligation port, so that the tissue to be ligated enters the ligation tube 5, which is used to ensure the accuracy of the ligation. The pull wire 7 is tightened continuously. When a certain tightening force is reached, the tail of the ligation coil 6 is disconnected, and the take-up wheel 3 stops working, and the ligation action is completed. The specific structure of the assembly is set as follows;

[0024] The ligation assembly includes a handle 2 arranged at the bottom of the stapler body 1, the handle 2 is connected to the stapler body 1, a wire take-up wheel 3 is arranged on the top of the handle 2, an extension tube 4 is arranged at one end of the stapler body 1, a ligation tube 5 is arranged in the extension tube 4, and a ligation coil 6 is arranged on the outside of the ligation tube 5;

[0025] A pull wire 7 is wound around the tying coil 6, and one end of the pull wire 7 extends to the take-up wheel 3;

[0026] A trigger 10 is provided on the handle 2, and a negative pressure switch 11 is provided on one side of the trigger 10. The negative pressure switch 11 is installed on the handle 2. A wire reel switch 13 is provided inside the handle 2, and the wire reel switch 13 is located on one side of the trigger 10. A negative pressure pump 8 is provided inside the handle 2, and a catheter 14 is provided on the negative pressure pump 8. One end of the catheter 14 passes through the stapler body 1 and the extension tube 4 and extends into the ligation tube 5. The negative pressure pump 8 is connected to the negative pressure switch 11. A driving device 9 is provided at one end of the negative pressure pump 8. A power supply 12 is provided inside the stapler body 1, and the power supply 12 is connected to the negative pressure pump 8 and the driving device 9 through a wire.

[0027] According to the above structure, when the device is in use, the ligation tube 5 is aligned with the tissue to be ligated, and the negative pressure pump 8 extracts the airflow through the catheter 14 during operation, so that negative pressure is formed at the ligation port, so that the tissue to be ligated enters the ligation tube 5, so as to ensure the accuracy of the ligation;

[0028] At the same time, by pulling the trigger 10, the trigger 10 can contact the wire-retrieving switch 13, so that the driving device 9 can start to drive the wire-retrieving wheel 3 to rotate and reel in the pulling wire 7. The pulling wire 7 pulls the ligation coil 6 in the extension tube 4 along a predetermined direction to tighten the root of the tissue to be ligated, and continues to tighten through the pulling wire 7. When a certain tightening force is reached, the tail of the ligation coil 6 is disconnected, and the wire-retrieving wheel 3 stops working to complete the ligation action. The negative pressure pump 8 is responsible for the negative pressure operation of the ligation mouth. When the ligation action is completed, the negative pressure switch 11 is turned on to complete the pressure relief, and then the instrument is taken out, and the next action of the cycle begins.

[0029] Different from the prior art, the present application discloses a disposable electric multi-ring ligation stapler, which aligns the ligation tube 5 with the tissue to be ligated, and starts the negative pressure pump 8 by turning on the negative pressure switch 11. When the negative pressure pump 8 is running, it extracts the airflow through the catheter 14, so that negative pressure is formed at the ligation port, so that the tissue to be ligated enters the ligation tube 5, which is used to ensure the accuracy of the ligation. The wire 7 is continuously tightened. When a certain tightening force is reached, the tail of the ligation coil 6 is disconnected, and the wire-reeling wheel 3 stops working, completing the ligation action.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
