A strip tracing device suitable for anal fistula ducts

Abstract

The invention discloses a strip tracing device suitable for anal fistula. The invention adopts the water flow tracing method, injects water from the outer opening of the fistula, and uses the fluidity of the water to find the inner opening of the fistula, which is efficient and fast, and does not harm the human body. Using the water flow to wrap the traction wire can directly bring the traction wire out of the inner opening of the fistula, and use the traction wire to bind the metal probe, which can efficiently complete the insertion of the metal probe into the anal fistula. Secondly, a confluence board is provided for fixing the pulling wire placement cavity, and a pulling wire outlet and a water flow channel are provided. A low-pressure area is formed around the exit of the traction line, which increases the water flow speed and at the same time ensures the coercive force of the water flow on the traction line, and ensures that the traction line rushes out with the water flow.

Description

technical field [0001] The invention relates to the field of anal fistula devices, in particular to a strip tracing device suitable for anal fistula ducts. Background technique [0002] Anal fistula is the abbreviation of anorectal fistula, which is the sequelae of abscess ulceration or incision drainage around the anorectum. like Figure 10 As shown, a typical anal fistula includes an external opening 91 of the fistula on the surface of the perianal skin of the human body 9, an internal opening 92 of the fistula outside the anal verge, or on the rectal wall, and a patency connecting the external opening 91 of the fistula and the internal opening 92 of the fistula However, in a serpentine and complete fistula 90, there may be multiple internal openings 92 of the fistula. [0003] Existing surgical methods are determined according to the penetration depth of the fistula 90, and the most important thing is to determine the position and number of the internal openings 92 of th...

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
