Cutting head component for scraping intestinal mucosa

Abstract

The invention relates to a cutting head component for scraping intestinal mucosa. The cutting head component is arranged on a handle for scraping the intestinal mucosa; the innovation point is that the cutting head component comprises a scraper head and an annular air storage cabin; a handle connecting section, a scraper section and a circular platform section are arranged on the outer surface ofthe scraper head; an annular scraper plate is arranged on the outer periphery of the scraper section; a cylindrical concave chamber with an internal thread is arranged at the center of the first end surface of the scraper head; the annular air storage cabin is jointed in the cylindrical concave chamber; a plurality of water spraying channels and air channels connected with the water spraying channels are uniformly distributed on the scraper head; the air channels are connected with the annular air storage cabin; the water spraying channels are communicated with an inner water supply joint. Thecutting head component has the advantages that air is utilized to drive water in the water spraying channels to impact the inner wall of the small intestine of the pig at certain speed, the sprayingis more uniform, the soaked intestinal mucosa layering is loose and the separation is thorough, and meanwhile, the inner wall of the small intestine of the pig is lubricated, the scraping is more smooth and the scraping efficiency is improved.

Description

technical field [0001] The invention relates to a scraping tool, in particular to a cutter head assembly for scraping intestinal mucosa. Background technique [0002] In the process of extracting crude heparin sodium from the small intestine of pigs, it is first necessary to scrape the mucous membrane from the small intestine. There are two traditional ways of scraping the mucous membrane: [0003] The first is manual scraping. The operator uses a scraper to repeatedly scrape and squeeze the mucosal layer of the inner wall of the small intestine in the same direction outside the small intestine, and squeeze the intestinal mucosa out of the small intestine; The small intestinal mucosa cannot come out with too much force, and excessive force can easily cause damage to the small intestine. Therefore, this method is labor-intensive, low in efficiency, and the yield of the intestinal mucosa is unstable; [0004] The second is mechanical scraping, which uses an intestine scraping...

Problems solved by technology

[0003] The first is manual scraping. The operator uses a scraper to repeatedly scrape and squeeze the mucosal layer of the inner wall of the small intestine in the same direction outside the small intestine, and squeeze the intestinal mucosa out of the small intestine; The small intestinal mucosa cannot come out with too much force, and excessive force can easily cause damage to the small intestine. Therefore, this method is labor-intensive, low in efficiency, and the yield of the intestinal mucosa is unstable;

[0004] The second is mechanical scraping, which uses an intestine scraping machine (casing casing machine). The scraping efficiency of the machine is higher, and the mucous membrane production rate is higher and more stable than that of traditional manual scraping. However, the specifications of the intestinal scraping machine are consistent The requirements are high, and the small intestines must be manually arranged one by one and put into the intestinal scraping machine. Therefore, the casings are often broken

However, since the intestinal scraping uses a circular scraper and moves in the small intestine, the scraper does not move as smoothly as the extraintestinal scraping, which limits the efficiency of intestinal scraping to a certain extent.
