Bougie tracing equipment and tracing method suitable for anal fistula pipeline

Abstract

The invention discloses bougie tracing equipment suitable for an anal fistula pipeline. A water flow tracing method is adopted, water is injected from an outer opening of the fistula pipeline, an inner opening of the fistula pipeline is found through the flowability of the water, high efficiency and rapidness are achieved, no harm is caused to a human body, a pull line is wrapped by water flow, the pull line can be directly brought out of the inner opening of the fistula pipeline, and a metal bougie is bound through the pull line, so that the metal bougie insertion work of the anal fistula pipeline can be efficiently completed. Secondly, a confluence plate is arranged and used for fixing a pull line containing cavity, a pull line outlet and a water flow channel are arranged, the water flow channel is arranged around the pull line outlet, the water flow in a confluence cavity can be guided into a confluence water outlet channel in a vortex rotation mode, a low-air-pressure area is formed around the pull line outlet, and the flow speed of the water flow is increased, so that the entrainment force of the water flow to the pull line is guaranteed, and the pull line rushes out along with the water flow.

Description

technical field [0001] The invention relates to the field of anal fistula equipment, in particular to a bougie tracing equipment suitable for anal fistula pipeline. Background technique [0002] Anal fistula is the abbreviation of anorectal fistula, which is the sequelae of abscess ulceration or incision drainage that occurs around the anorectum. Such as Figure 10 As shown, a typical anal fistula includes an external opening 91 of the fistula tract on the perianal skin surface of the human body 9, an internal opening 92 of the fistula tract outside the anal edge, or on the rectal wall, and a patency connecting the external opening 91 of the fistula tract and the internal opening 92 of the fistula tract. However, in a meandering complete fistula tract 90, there may be multiple internal openings 92 of the fistula tract. [0003] Existing surgical methods depend on the penetration depth of the fistula 90, and the most important thing is to determine the position and number of...

AI Technical Summary

Problems solved by technology

[0006] 1. Because the pipeline formed by anal fistula is not a straight tube, the general anal fistula pipeline is as figure 1 As shown, there are a large number of holes and tortuous pipelines. Therefore, it is difficult to directly reach the other end of the anal fistula after using a metal bougie to penetrate along the anal sinus. Instead, it is easy to penetrate the inside of the abscess cavity and cause bleeding or the spread of secondary infection.

[0007] 2. In the actual operation, there are still cases where the same anal fistula forms multiple openings. Therefore, when the metal bougie is perforated, the difficulty of the operation is increased. The existing operation can only use manual trial and error, and directly interspersed to find The inside of the anal fistula, if you find the exit, it is very easy to damage the human tissue and cause secondary injury
