Abstract
The present invention provides a surgical anastomosting material for liver, spleen and kidney operation cut. The production process of absorptive animal protein fiber net incldues washing sheep or deer intestine, soaking in softened water, scraping, degreasing in sodium hydroxide solution, bleaching with hydrogen peroxide, processing with ethyl acetate and chromium salt solution, washing and drying, crushing, mixing with biogum, extruding to form yarn, weaving net, packing, disinfection and other steps. It is compatible with human organs and high in strength and can make operation simplified and the cut quick heal.
Description
The present invention relates to medical surgical surgical stapling material manufacture technology, the manufacturing process of the absorptive animal protein fibre net that especially a kind of human body viscera surgical operation is used.
Application number is 99111431.0 application for a patent for invention, disclose a kind of Munufacture of medical absorbable soft suture, its technology is that fresh Intestinum caprae seu ovis is cleaned, check anosis after, through mechanical striking, biochemical treatment and packaging sterilizing, make the medical not damaged soft suture-thread that absorbs.At present, when making the human body viscera surgical operation, mainly be to adopt this absorbable suture to sew up the edge of a knife.In surgical operation is clinical, because liver, spleen and renal tissue performance are more crisp, and the more high reason of the hemorrhage pressure of wound face, cause the difficulty that adopts this stitching thread to operate big, the treatment success rate is low.
Purpose of the present invention aims to provide a kind of manufacturing process of medical absorptive animal protein fibre net, postoperative liver, spleen and kidney tightly can be bound by its net of making, and the reuse absorbable tamps.
The object of the present invention is achieved like this: the fresh primitive gut of sheep or deer is cleaned, after the no disease of check, soaked a period of time in demineralized water, slightly scrape with thick archenteron-scrapping machine; Casing after slightly scraping is put into 20% sodium hydroxid aqueous solution and is soaked, and the softening clean water of reuse is cleaned; With cutter casing is broken into some, put into hydrogen peroxide solution and bleach; Clean carefully the scraping again of casing bar after the bleaching cleaned; Put into 0.1 ‰ chrome liquor, add ethyl acetate simultaneously and carry out deciding chromium, decide chromium afterwash and airing; The casing bar of airing is ground into powdery, adds the biogum of 3-4%, stir, under 70-80 ℃ temperature, make the azelon silk of certain specification with extruding strings device; Adopt conventional textile technology, the azelon silk weaving is become the strand knitmesh of certain specification; Then to anastomose thermal finalization, and carry out physical property and detect and take off the chromium test; Be cut into the net sheet or make mesh bag according to certain specification at last, medical absorptive animal protein fibre net is made in packing and sterilization.
Owing to adopt the made absorptive animal protein fibre net of technique scheme, tissue intersolubility is extremely strong with human body viscera, use this fleece that postoperative liver, spleen or kidney are tightly bound, the reuse absorbable tamps, in 15 days, fleece just loses tension force, and is progressively all absorbed by human body.The fleece fracture strength is big, easy, the safety of performing the operation, and wound healing is fast, good operation effect.
The invention will be further described below in conjunction with embodiment.
The fresh small intestinal of sheep or deer is cleaned, through check anosis after, be immersed in 5 ℃ of-10 ℃ of demineralized waters, after 12 hours, take out, on thick archenteron-scrapping machine, slightly scrape, put into 20% sodium hydroxid aqueous solution and soaked 2 hours, the softening clean water of reuse is cleaned, and with cutter casing is broken into some then, put it in 20 ℃ the hydrogen peroxide solution bleaching 4 hours, casing bar washes clean after the bleaching is carefully scraped, and 0.1 ‰ chrome liquor is put in the washing of reuse clean water, add 1 ‰ ethyl acetate simultaneously, carry out deciding chromium after 12 hours, wash again three times, then airing; With behind the airing the casing bar be ground into powdery, the powdery granularity adds 3.5% biogum again less than 600 orders, stirs; Under 75 ℃ constant temperature, make the azelon silk with the plastics extruding strings device, its diameter is 0.21mm or 0.15mm; According to conventional textile technology, the azelon silk is made into strand knitmesh on the ordinary loom of repacking, the mesh specification is 4.5mm * 4.5mm or 4.0mm * 4.0mm, then anastomose is carried out thermal finalization, and carry out the physical property detection and take off the chromium test, be cut into the net sheet or make mesh bag according to certain specification at last,, make medical absorptive animal protein fibre net through packing and sterilization.
Claims (1)
1, a kind of manufacturing process of medical absorptive animal protein fibre net, it is earlier the fresh primitive gut of sheep or deer to be cleaned, and after the no disease of check, soaks a period of time in demineralized water, slightly scrapes with thick archenteron-scrapping machine; Casing after slightly scraping is put into 20% sodium hydrate aqueous solution and is soaked, and the softening clean water of reuse is cleaned; With cutter casing is broken into some, put into hydrogen peroxide solution and bleach; Carefully scrape again clean the casing bar after the bleaching; Put into 0.1 ‰ chrome liquor, add ethyl acetate simultaneously and carry out deciding chromium, decide chromium afterwash and airing, it is characterized in that: the casing bar of airing is ground into powdery, adds the biogum of 3-4%, stir, under 70-80 ℃ temperature, make the azelon silk of certain specification with extruding strings device; Adopt conventional textile technology, the azelon silk weaving is become the strand knitmesh of certain specification; Then to anastomose thermal finalization, and carry out physical property and detect and take off the chromium test, be cut into the net sheet or make mesh bag according to certain specification at last, medical absorptive animal protein fibre net is made in packing and sterilization.
