Reusable anorectal ligator with filter assembly

Abstract

The invention discloses a reusable anorectal ligator with a filter assembly. The ligator comprises a handle, a ligation mechanism, a firing mechanism, a suction mechanism and a control mechanism. Theligation mechanism comprises an inner barrel, a push sleeve, a stringing assembly and the filter assembly. The push sleeve sleeves the inner barrel. The firing mechanism comprises a firing switch, a guide push block and a vent pipe top seat. The vent pipe top seat is fixedly connected in the handle, and the guide push block is in sliding connection to the vent pipe top seat. The firing switch is rotatably connected to the handle. The suction mechanism comprises a four-way pipe and a negative pressure pump. The four-way pipe is respectively communicated with the vent pipe top seat, the negativepressure pump, a pressure relief assembly and a sensor connection pipe. The control mechanism comprises a controller and a pressure sensor. A probe of the pressure sensor is disposed in the sensor connection pipe, and the pressure sensor is connected to the controller. The ligator can prevent medical staff from reusing a disposable assembly, can prevent foreign matters from entering the matched handle, can avoid infection and is safe to operate.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a reusable anorectal ligation device with a filter assembly. Background technique [0002] The common way to treat hemorrhoids is to use band ligation. The principle is to tie a special rubber ring on the root or base of hemorrhoids, and use the elastic retraction force of the rubber ring to block the blood supply of hemorrhoids, making them necrotic, shrinking, and falling off, so as to achieve cure. Objective: At present, the instruments used for ligation surgery generally use a ligation device, which absorbs the upper mucosa of female hemorrhoids through vacuum, and blocks the superior hemorrhoidal artery immediately after ligation with elastic threads, so as to achieve the purpose of minimally invasive hemorrhoids. [0003] Most of the existing ligation devices on the market are hand-held guns, which can only be used once. However, under the requirements of low cost and low c...

AI Technical Summary

Problems solved by technology

[0005] The above technical solutions, 1. There is no structure to prevent the same set of straws and push rods from being reused. If medical staff fail to replace the straws and push rods for reasons such as being in a hurry, problems such as cross-infection of germs may occur, which is not conducive to the treatment and rehabilitation of patients; 2. 1. The storage tank needs to be cleaned. If it is not cleaned or does not meet the medical requirements for disinfection, it is easy to breed bacteria, which is not conducive to repeated use; 3. The battery cannot be charged and has poor battery life; 4. The straw of the existing ligation device Filters cannot be realized in parts used to contact lesions, and it cannot effectively prevent human tissue from being sucked into the vacuum pump during the negative pressure suction process.
