Thaum kev phais, yuav tsum tau txuas cov ntaub so ntswg, cov hlab ntsha. Suture cov ntaub ntawv hauv kev phais tau dhau los ua ib qho kev hloov pauv, thiab niaj hnub no lawv muaj ntau yam khoom tshwj xeeb uas ua rau kev kho mob sai sai. Cov tshuaj niaj hnub no kuj tau coj mus rau hauv tus account ntawm cov tshuaj pleev ib ce: cov stitches ua tsis tshua pom, thiab feem ntau tsis muaj kab ntawm lawv txhua.
Cov Khoom Taw Qhia Cov Khoom Taw Qhia
Suture cov ntaub ntawv yuav tsum muaj ntau lub peev xwm tshwj xeeb. Ua ntej tshaj plaws, cov khoom no yuav tsum tsis txhob muaj tshuaj lom, ua rau muaj kev tsis haum tshuaj. Lwm qhov tsim nyog zoo yog tiv thaiv kom tsis muaj menyuam, vim tias nws yog qhov tsis muaj cov kab mob pathogenic uas tseem ceeb heev thaum muaj kev cuam tshuam kev phais. Thiab, ntawm chav kawm, cov ntaub ntawv suture yuav tsum muaj zog, tsis txhob raug mob cov ntaub so ntswg uas nws dhau mus. Nws elasticity thiab muaj peev xwm tsim cov pob caus kuj tseem ceeb. Tag nrho cov ntaub ntawv yuav ua tau nyob rau hauv daim ntawv ntawm ib tug xov tooj los yog tsim los ntawmob peb (torsion, weaving). Nyob ntawm qhov muaj peev xwm ntawm cov khoom rau biodegrade, kev faib tawm ntawm cov khoom siv suture zoo li no: cov xov uas absorbable, maj mam absorbable, thiab cov uas tsis nqus tag nrho. Tsis tas li ntawd, xws li cov khoom hauv kev phais tuaj yeem yog ob qho tib si ntuj thiab hluavtaws.
Cov khoom tsis nqus tau
Cov ntaub ntawv zoo sib xws tau siv txawm tias ua ntej qhov tshwm sim ntawm cov analogues niaj hnub no. Txawm li cas los xij, txawm tias tam sim no lawv tau siv dav hauv cov xwm txheej uas tsim nyog kom tau txais kev sib txuas muaj zog thiab txhim khu kev qha. Nyob rau hauv cov ntaub ntawv no, cov ntaub yuav tuav tau ntev los ntawm ib tug zoo sib xws seam. Cov pawg no suav nrog cov xov paj ntaub (raws li qhov nqus tau, vim lawv pom tsis tau tom qab ob peb xyoos), lavsan, polypropylene, polyvinyl, hlau khoom, staples. Silk muaj lub zog ncaj ncees. Xws li ib tug xov yog heev yooj yim rau manipulate, khi knots. Hauv qhov no, cov tshuaj tiv thaiv hauv cov ntaub so ntswg feem ntau pom. Feem ntau cov khoom siv suture no yog siv nyob rau hauv ophthalmology, phais yas, thiab thaum lub sij hawm ua hauj lwm ntawm lub plab hnyuv ib ntsuj av. Inert threads muaj xws li polypropylene. Vim nws lub zog siab, nws yog siv thaum thov cov phiajcim, kho ntau yam khoom. Cov hlau xaim hlau yog ua los ntawm cov hlau zoo thiab tuaj yeem siv los txuas cov sternum seem, thiab lwm yam.
Lavsan hauv kev phais
Cov khoom siv phais mob phais raws li polyester muaj qhov zoo tsis txaus ntseeg: siablub zog, tuav zog kuj nyob rau theem. Tsis tas li ntawd, nws tsis tshua muaj tshwm sim hauv cov ntaub so ntswg. Nws los ntawm ntau hom: twisted, braided, coated nrog fluororubber. Tus nqi ntawm cov xov zoo li no kuj tsawg. Feem ntau, xws li cov khoom siv suture yog siv thaum lub sij hawm cov ntaub so ntswg prosthetics, thaum lub sij hawm ua hauj lwm nyob rau hauv nyuaj-rau-kho qhov chaw, raws li zoo raws li cov cheeb tsam uas qhov nro tas li. Txawm li cas los xij, kuj tseem muaj ntau qhov tsis zoo. Nyob hauv lub cev tas li, cov xov zoo li no tuaj yeem ua rau mob.
Ib yam ntxwv ntawm cov khoom siv resorbable. Catgut
Cov khoom hauv pawg no tuaj yeem yog ntuj lossis hluavtaws. Catgut suav hais tias yog ntuj. Qhov kev phais phais no yog tsim los ntawm cov hnyuv me ntawm cov tsiaj nyeg (zoo), uas tau ua tiav hauv txoj kev tshwj xeeb. Thaum xub thawj, cov khoom zoo li no muaj lub zog txaus, tab sis tsis ntev nws poob. Hauv ib lub lis piam lossis ob, nws cov ntsuas tau txo qis ib nrab. Yuav kom lub sij hawm resorption nce me ntsis, catgut yog kho nrog chromium ntsev. Qhov no manipulation doubles lub sij hawm dissolution. Nws tseem yog ib qho tseem ceeb uas yuav tsum nco ntsoov qhov tseeb tias cov khoom siv suture absorbs txawv nyob ntawm seb cov ntaub so ntswg nyob rau hauv uas nws tau muab tso rau, nrog rau kev siv ntawm cov ntshav mus rau qhov chaw no, thiab tus kheej yam ntxwv ntawm lub cev. Qhov tsis zoo muaj xws li qhov tawv ntawm cov xov, nrog rau qhov muaj peev xwm ntawm kev tsis haum tshuaj. Cov ntawv thov tseem ceeb yog gynecology, urology, ua pa thiab digestive, qhov txhab kaw.
Synthetic absorbable sutures
Hom no suav nrog cov tshuaj uas muaj cov khoom zoo. Thaum siv lawv, nws yog ib qho yooj yim los twv seb lub sij hawm ntawm lub zog poob. Tsis tas li ntawd, cov xov zoo li no yooj yim ua haujlwm nrog, lawv muaj zog heev. Lwm undoubted plus yog inertness thiab tsis muaj kev tsis haum tshuaj. Ib qho ntawm ntau yam - polyglycolide suture khoom yog absorbable. Nws yog tus cwj pwm los ntawm kev muaj zog ntxiv thiab muaj peev xwm tuav lub qhov txhab thaum lub sij hawm tseem ceeb ntawm kev kho. Dexon yog ib qho ntawm cov khoom siv feem ntau siv hauv kev phais dav dav, nrog rau hauv gynecology thiab urology. Xws li cov khoom siv hluavtaws muaj lub hauv paus chiv keeb. Lawv yog cov polymers ntawm lactic acid. Tom qab cov xov tau nkag mus rau hauv cov ntaub so ntswg, cov txheej txheem ntawm hydrolysis tshwm sim. Thaum kawg ntawm tag nrho cov tshuaj tiv thaiv, cov khoom suture decomposes rau hauv dej molecules thiab carbon dioxide. Synthetic absorbable sutures feem ntau yog siv los txuas cov ntaub so ntswg ntawm lub plab thiab pleural kab noj hniav. Nyob rau hauv cov cheeb tsam no, lub sij hawm rov tsim dua yog los ntawm ib lub lis piam mus rau ib hlis, thaum nws coincides nrog txo cov khoom siv zog.
Vikryl - cov khoom siv rau kev koom nrog cov ntaub so ntswg
Txhawm rau txuas cov ntaub so ntswg thiab thaj chaw uas tsis tas yuav tsum tau ua kom nruj, cov khoom siv niaj hnub Vicryl yog siv. Nws yog cov khoom siv hluavtaws thiab muaj glycolide thiab L-lactide. Cov ntaub so ntswg thaum nws siv yog tsawg, lub zog txo qis tom qab 4 lub lis piam. Ua kom tiav kev tawg hauv lub cevtshwm sim los ntawm hydrolysis tom qab 50-80 hnub. Cov xov zoo li no yog siv hauv ophthalmology thiab gynecology. Tab sis cov cheeb tsam uas nws siv tsis tau zoo yog neurosurgery thiab phais plawv. Vicryl yog cov khoom siv suture uas tuaj yeem muab cov khoom tsis muaj xim lossis xim liab. Xov muaj nyob rau hauv txawv thicknesses thiab lengths. Cov khoom siv kuj tseem muaj cov koob stainless hlau.
khaws cia cov sutures
Yuav kom cov xov kom khaws lawv lub cev lub cev, nws yog ib qho tseem ceeb uas yuav tsum tau ua raws li qhov ntsuas kub kom raug. Suture cov ntaub ntawv hauv kev phais poob lub zog yog tias khaws cia ntawm qhov kub siab tshaj 30 ° C lossis ntawm qhov tsis zoo. Yog tias cov xov tau raug tshem tawm ntawm lub ntim tab sis tsis siv, nws yuav tsum muab pov tseg. Nws tseem yog ib qho tseem ceeb kom taug qab cov hnub tas sij hawm. Tom qab lawv tas sij hawm, cov khoom hloov me ntsis. Kev sib cuag nrog cov dej noo kuj yog qhov tsis xav tau. Re-sterilization ntawm cov ntaub ntawv suture yog tsis tso cai.
