Thread ligating device for anal fistula

Abstract

The invention discloses a thread ligating device for anal fistula. The device comprises a probe, a transmission flexible shaft, an iron ball, a boring head, a cutter head, an endoscope, an inflator and a thread. The probe is internally provided with a passage, and the tail end of the probe is provided with a liquid inlet. A syringe is arranged at the liquid inlet, an annular groove is formed in the outside the front end of the probe, an air bag is arranged around the annular groove, and an air inlet pipe is arranged in the passage. One end of the air inlet pipe is connected with the air bag, and the other end is connected with the inflator device. The top end of the probe is provided with a hemispherical groove for holding the iron ball and communicated with the passage. The hemisphericalgroove is provided with an electromagnet, and the tail end of the probe is provided with a battery case. A switch button of the electromagnet is disposed at the tail end of the battery case. The middle of the iron ball is provided with a through hole, and the front end of the thread is connected with the iron ball. The tail end of the thread passes through the passage and stretches out of the liquid inlet. The top end of the endoscope is provided with a magnet, and the tail end of the passage is provided with a seal ring. The top end of the transmission flexible shaft is provided with a connection end connected with the cutter head or the boring head, and the tail end of the transmission flexible shaft is connected with a driving motor.

Description

technical field [0001] The invention relates to an anal fistula thread-hanging device, in particular to a device for anal fistula thread-hanging. Background technique [0002] The current anal fistula is the sequelae of abscess ulceration or incision drainage that occurs around the anorectum. A typical anal fistula is a smooth and complete pipeline, one end is in the anal sinus, the other end is outside the anal edge, or in the rectal wall. Atypical anal fistula generally only has an internal opening but no external opening, or although there is an internal opening and an external opening, the middle fistula is blocked, or there is only an external opening, and the internal opening cannot be found, or there is only one induration. [0003] Now most of the clinical treatment is hanging thread treatment. In hanging thread treatment, firstly, under anesthesia, the probe is inserted through the fistula through the outer opening, and a sterilized rubber band or medicinal thread i...

AI Technical Summary

Problems solved by technology

The head of the probe is blunt and usually spherical. It is difficult to pass through the fistula when it encounters blockage during insertion. After passing through the fistula, it is necessary to pull out the rubber band or medicine thread by inserting your fingers and then tie it tightly. line, which not only increases the operation time but also increases the pain of the patient

[0004] At present, there is no anal fistula thread hanging device that can easily pass through the fistula tract and pull out the rubber band or medicine thread without inserting fingers. The anal fistula thread-hanging device for patients with pain has a broad market prospect
