Disposable controllable negative-pressure multi-continuous-jet haemorrhoid loop ligature device

Abstract

The invention relates to a disposable controllable negative-pressure multi-continuous-jet haemorrhoid loop ligature device. The disposable controllable negative-pressure multi-continuous-jet haemorrhoid loop ligature device is characterized by comprising a gun shell (1), wherein a fixed seat (6) is arranged on the upper end of the gun shell (1); a suction pipe tail seat (7) is arranged in the fixed seat (6); one end of the suction pipe tail seat (7) is connected with a suction pipe (4); a plurality of pushing rings (3) are sleeved on the outer part of the front end of the suction pipe (4); pushing pipes (5) are sleeved on the outer parts, at the rear sides of the pushing rings (3), of the suction pipe (4); the pushing pipes (5) are connected with a loop ligature wrench (11); and the loop ligature wrench (11) provides power so that the pushing pipes (5) can do straight reciprocating motion. The disposable controllable negative-pressure multi-continuous-jet haemorrhoid loop ligature device provided by the invention is wide in applicable range, convenient to operate and shorter in loop ligature time; the continuous-jet haemorrhoid loop ligature can be realized and the treatment effect is improved; and meanwhile, self-destruction can be realized and cross infection can be prevented.

Description

technical field [0001] The invention relates to a one-time-use controllable negative pressure multi-sequence hemorrhoid ligation device, which is mainly used for hemorrhoid ligation treatment to achieve the effect of minimally invasive treatment of hemorrhoids, and belongs to the technical field of medical devices. Background technique [0002] After humans evolved to walk upright, hemorrhoids came immediately. The treatment of hemorrhoids is mainly divided into drug treatment, instrument treatment, 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 "hemor...

AI Technical Summary

Problems solved by technology

[0004] 1. The negative pressure of the ligation device with its own negative pressure is fixed and limited, cannot be adjusted, and is difficult to control. The suction of the negative pressure is not enough, and it is not easy to operate, which makes it unsuitable for hemorrhoids with large diameters.

[0005] 2. The mechanism of the ligation device with its own negative pressure is complicated, and the operation is cumbersome. It is very difficult to put the ligation rubber ring on the ligation device, and the ligation time is longer

[0006] 3. The ligation device with its own negative pressure uses a single shot when ligation, and the ligation efficiency is low

[0007] 4. The ligation device with external negative pressure has large limitations and poor adaptability, and has very high requirements for ligation treatment conditions

[0008] 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

[0009] 6. For the ligation device with external negative pressure, because the ligation ring at the key part is ligated on the negative pressure suction port of the appliance 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

[0010] 7. Neither the ligator with its own negative pressure nor the ligator with external negative pressure can achieve self-destruction after multiple uses of the ligature gun, and it will cause cross-infection after multiple uses
