Disposable negative-pressure loop ligation appliance for hemorrhoids of patients

Abstract

The invention relates to a disposable negative-pressure loop ligation appliance for hemorrhoids of patients. The disposable negative-pressure loop ligation appliance is characterized by comprising a gun shell, a fixing seat is mounted at the upper end of the gun shell, a cannula is fixed to the front end of the fixing seat, a push tube is sleeved on an outer layer of the cannula, a suction port is arranged at the front end of the cannula, an expansion tube is inserted in the suction port, two outlets are arranged at the rear end of the cannula, one outlet is connected with a check valve, the other outlet is connected with an air inlet valve, a negative-pressure cylinder is further arranged in the middle of the inside of the gun shell, an air inlet of the negative-pressure cylinder is communicated with another port of the check valve, the front end of a piston rod in the negative-pressure cylinder is connected with a negative-pressure trigger, and a loop ligation trigger is arranged on the lower side of the fixing seat and is hinged with the rear end of the push tube. The disposable negative-pressure loop ligation appliance for the hemorrhoids of the patients has the advantages that the disposable negative-pressure loop ligation appliance is convenient and speedy and is simple in operation when used in loop ligation treatment for hemorrhoids of a patient, cross infection is prevented, suffering of the patient is relieved, and the disposable negative-pressure loop ligation appliance is applicable to hospitals in various environments and is obvious in loop ligation effect.

Description

technical field [0001] The invention relates to a disposable negative pressure hemorrhoid ligation device, which is mainly used for hemorrhoid ligation to achieve the effect of minimally invasive treatment of hemorrhoids, and belongs to the field of medical devices. Background technique [0002] After humans evolved to walk upright, hemorrhoids came immediately. Therapeutic methods of hemorrhoids are mainly divided into drug therapy, device therapy and surgical treatment. At the end of the 1950s, European and American countries invented a new treatment method, rubber ligation treatment technology, which achieved remarkable results and was rapidly promoted. The promotion of this treatment technology in our country came out in the 20th century. According to the characteristics of this treatment technology, our company invented and promoted the first generation of "disposable hemorrhoid ligation device" and the matching "hemorrhoid treatment anoscope" in 2006. Later, some hem...

AI Technical Summary

Problems solved by technology

[0003] 1. Self-contained negative pressure ligation device, limited negative pressure fixation, non-adjustable, difficult to control, insufficient negative pressure suction, difficult to operate, not suitable for hemorrhoids with larger diameters

[0004] 2. The mechanism of the self-contained negative pressure ligation device is complicated, the operation is cumbersome, it is difficult to apply the ligation rubber ring, and the ligation time is long

[0005] 3. The self-contained negative pressure ligation device adopts single-shot ligation, and the ligation efficiency is low

[0006] 4. The external negative pressure ligation device has large limitations and poor adaptability, and has very high requirements for ligation treatment conditions

[0007] 5. There is no auxiliary anoscope for the external negative pressure ligation device, which is inconvenient to operate and requires 2-3 people to cooperate with the operation. The ligation time is long and it is easy to cause cross infection

[0008] 6. Since the key part of the external negative pressure ligation device is ligated on the negative pressure suction port of the device for a long time, the resilience of the ligation ring is poor, the effect of ligation treatment is poor, and various complications are prone to occur. Increase the pain of the patient and fail to achieve the therapeutic effect
