Problems solved by technology

[0002] At present, the domestic treatment of anal fistula generally adopts one-time incision or incision and thread-hanging operation, which may easily cause different degrees of anal incontinence after the operation, seriously affecting the quality of life of patients
In order to avoid anal incontinence after anal fistula surgery, anal fistula plug and push valve technique are often used, but the recurrence rate is very high. The main reason for the recurrence is that the inflammatory diseased tissue on the anal fistula wall cannot be effectively removed
In the prior art, there is no device that can effectively and completely remove the inflammatory diseased tissue on the wall of the anal fistula

Embodiment Construction

[0012] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0013] Such as figure 1 , figure 2 , image 3 As shown, the device for scraping and cleaning the wall tissue of anal fistula includes a scraper rod 1. A scraper brush 2 is provided at one end of the scraper rod 1, and a threaded scraper is provided at the other end of the scraper rod 1. The convex rib 3 is provided with a first cleaning guide block 22 with a first cavity 21 at the outer end of the scraper brush 2. The outer diameter of the first cleaning guide block 22 is smaller than the outer diameter of the scraper brush 2. The outer wall of the cleaning guide block 22 is evenly distributed with a number of first water spray holes 23 communicating with the first cavity 21 in the first cleaning guide block 22, and the outer end of the scraping rib 3 is provided with a second cavity. In the second cleaning guide block 32 of the cavity 31, the outer diameter...

Abstract

The invention discloses an anal fistula wall tissue scraping and cleaning device, which comprises a scraping rod, and is characterized in that one end of the scraping rod is provided with a scraping brush, the other end of the scraping rod is provided with a helical scraping rib, both the outer end part of the scraping brush and the outer end part of the scraping rib are provided with a cleaning guide block with a cavity, the outer wall of each cleaning guide block is provided with a plurality of water spraying holes communicated with the corresponding cavity, the side wall of the middle partof the scraping rod is provided with a water inlet hole, the cavity in each cleaning guide block is communicated with the water inlet hole through a water inlet channel arranged in the scraping rod, there is a steering valve at the water inlet hole, and the steering valve enables the water inlet hole to be not simultaneously communicated with the cavities in the two cleaning guide blocks. The analfistula wall tissue scraping and cleaning device has the beneficial effects that the operation is convenient, the scraping rib and the scraping brush are enabled to rotate and lift at inflammatory lesion tissue parts of the anal fistula wall, and the anal fistula wall is sprayed with water and cleaned at the same time so as to effectively remove the inflammatory lesion tissues on the anal fistulawall.

Description

Technical field [0001] The invention relates to the technical field of anal surgical instruments, in particular to an anal fistula tube wall tissue scraping and cleaning device. Background technique [0002] At present, the domestic treatment of anal fistula generally uses a single incision or incision and thread-drawing operation, which may easily cause different degrees of anal incontinence after the operation, which seriously affects the quality of life of patients. In order to avoid anal incontinence after anal fistula surgery, anal fistula plug and sliding flap technology are often used, but the recurrence rate is high. The main reason for the recurrence is the inability to effectively remove the inflammatory tissue on the wall of the anal fistula. There is no device in the prior art that can effectively and completely remove the inflammatory tissue on the wall of the anal fistula. Summary of the invention [0003] The object of the present invention is to provide an anal fi...
