Cov tshuaj niaj hnub niaj hnub hloov kho tas li nrog txhua yam tshiab. Cov xov catgut yog ib qho ntawm lawv, nrog rau nws cov kev pab koj tuaj yeem ua tus kheej-absorbable suture, uas tsis tas yuav tsum tau saib xyuas thiab mus rau tsev kho mob rau hnav khaub ncaws thiab tshem tawm. Nws muaj kev nyab xeeb thiab siv tau. Nrog nws cov kev pab, cov seams sab hauv yog tsim, uas yaj ntawm lawv tus kheej tom qab ib pliag. Qhov no yooj yim heev, vim koj tsis tas yuav nyob hauv tsev kho mob ntev ntev raws li kev saib xyuas ntawm cov kws kho mob.
Catgut yog txhais ua "cov hnyuv ntawm nyuj". Catgut yog dab tsi? Qhov no yog ib tug self-absorbable suture khoom, uas yog siv nyob rau hauv kev phais. Rau nws kev tsim khoom, purified connective ntaub so ntswg yog siv. Feem ntau, cov ntaub so ntswg los ntawm cov hnyuv ntawm cov nyuj los yog submucosal ib feem ntawm cov hnyuv ntawm yaj yog siv. Lwm cov khoom siv yog siv hauv cov khoom siv suab paj nruag, uas yog cov hlua rau cov twj paj nruag.
Yuav ua li cas
Raws li twb tau hais lawm, rau nws cov khoom siv, cov leeg nqaij txheej ntawm txoj hnyuv lossis submucosal ib feem ntawm txoj hnyuv ntawm yaj thiab nyuj yog siv. Txhawm rau tsim cov xov zoo li no, koj yuav tsum ua ntau tshaj 10 txoj haujlwm, qhov no yog txheej txheem nyuaj. Cov khoom siv raw rau kev tsim khoom tuaj rau hauv daim ntawv qhuav lossis ntub dej ntsev. Ua ntej, nws yog kho nrog ib tug tshwj xeeb tov ntawm potash, tom qab uas nws yog mechanically cuam tshuam los ntawm scrapers thiab txiav mus rau hauv ib daim hlab. Tom qab ntawd muaj cov txheej txheem bleaching nyob rau hauv ib tug daws ntawm sodium thiab perhydrol, tom qab uas nws yog twisted rau hauv xov. Tom qab ntawd lawv yog fumigated nrog sulfuric gas thiab rinsed nyob rau hauv acetic acid, tab sis tsis concentrated. Tom qab tag nrho cov no, nws yog qhuav, polished thiab calibrated nyob ntawm seb lub thickness. Nyob rau theem kawg, cov txheej txheem xws li degreasing nrog roj av, sterilization nrog tshuaj-hom reagents tshwm sim, thiab thaum kawg lawv tau twisted rau hauv coils thiab ntim.
Variety
Muaj ntau ntau yam ntawm catgut. Txij li nws yog ib txoj hlua phais, nws yuav tsum tau siv nyob rau hauv kev khiav hauj lwm sib txawv, yog li nws tsis tuaj yeem ua tib yam rau txhua txoj haujlwm thiab cov xwm txheej. Catgut yog qhov txawv:
- simple;
- chrome plated.
Qhov yooj yim version yog ib qho kev phais zoo tib yam. Nws tsis tau ua tiav ntxiv, uas, dhau los, tsis ncua lub sijhawm resorption.
Txiv kab ntxwv catgut - yog dab tsi? Nws zoo li ib tug elastic xov, muaj ib tug du nto nyob rau hauv cov xim ntawm creammus rau lub teeb xim av. Siv rau hauv plab hnyuv mucosa, urology, gynecology, nqaij, fascia, fiber, plab kab noj hniav, parenchymal kab mob, bronchi, ntsws, traumatology. Catgut daws tau li ntawm 7 mus rau 12 hnub. Thaum lub sij hawm no, nws lub zog yog txo mus rau 50%. Tshem tawm ntawm lub cev tsis pub dhau 70 hnub los ntawm kev ua enzymatic. Cov xov yog sterilized los ntawm txoj kev tawg.
Chrome catgut - yog dab tsi? Raws li lub npe implies, xov yog kho nrog chromium ntsev thiaj li ua rau kom lub sij hawm resorption. Chromium ntsev tsim ntxiv molecular bonds uas yog teem transversely. Outwardly, qhov no yog tib yam elastic xov, uas muaj ib tug du nto ntawm lub teeb ntsuab los yog ntsuab xim. Nws yog siv nyob rau hauv tib rooj plaub uas dog dig catgut siv, tab sis nyob rau hauv cov ntaub ntawv uas lub sij hawm rov qab yuav ntev dua. Lub sijhawm uas cov xov poob 50% ntawm nws lub zog yog 18-28 hnub. Nws tawm hauv lub cev hauv 90 hnub los ntawm txoj kev enzymatic, thiab ua kom tsis muaj menyuam los ntawm txoj kev tawg.

Kev phais xov los ntawm catgut yog cov reactogenic tshaj plaws. Cov kev tshawb fawb sim tau pom tias thaum lub qhov txhab huv yog sutured nrog cov xov zoo li no, tsuas yog 100 staphylococcus microbes txaus los tsim suppuration. Qee zaum, lub sijhawm ntawm resorption yuav txawv, yog li nws tsis tuaj yeem hais meej sai npaum li cas cov xov yuav daws tau. Qee zaum, nrog kev phais ntawm lub plab thiab kev siv catgut thaum lub sijhawm rov qab los, nws tuaj yeem daws tau hauv thawj ob peb hnub. Tom qab 10 hnub, cov xov yuav twb poob mus txog ib nrab ntawm nws lub zog. Tsis tas li ntawd, nyob rau hauv cov xwm txheej sib npaug, lub zog ntawm cov xov hluavtaws yog ntau dua li ntawm catgut, qhov no yuav tsum tau siv cov xov ntawm txoj kab uas hla. Ib qho ntawm cov yam ntxwv ntawm cov xov yog tias nws muaj peev xwm nqus tau. Kev siv cov catgut tsis pom zoo rau cov neeg mob ua xua, vim nws muaj qhov ua xua heev.
Suture
Ib xov yog suav tias yog cov khoom siv phais phais, nws txuas cov ntaub so ntswg, tsim cov caws pliav lossis epithelialization.
Cov khoom yog thawj zaug siv ntau txhiab xyoo dhau los. Nws tau tham hauv kev kho mob ntawm Suav tshuaj. Tab sis nyob rau hauv cov hnub, nees plaub hau, paj rwb, ntoo fibers thiab tsiaj tendons tau siv, koj pom, ib daim ntawv teev cov ntaub ntawv tsis zoo nkauj heev. Thiab hais txog catgut, thiab nws yog dab tsi, tsis muaj leej twg paub.
Hnub no, cov xov paj ntaub yog suav tias yog qhov kev xaiv zoo tshaj plaws hauv kev phais. Tag nrho ua tsaug rau nws cov khoom, nws yog mos, yas, ruaj, thiab nws tuaj yeem knitted hauv ob lub pob. Vim lub fact tias txhob lo lo ntxhuav yog ib yam khoom ntuj, nws cov khoom muaj peev xwm muab piv nrog catgut, tab sis cov tshuaj tiv thaiv kab mob ntawm cov xov xov yog tsawg pronounced. Cov xov kuj ua rau mob, thaum mob hnyav, necrosis tuaj yeem tshwm sim. Txhawm rau ua rau suppuration, nws tsuas yog siv 10 microbial lub cev, xws li qhov xaus ntawm qhov kev sim. Nyob rau hauv luv luv, txhob lo lo ntxhuav thiab suture catgut zoo ib yam thiab muaj tib lub zog, tab sis muaj qhov sib txawv: txhob lo lo ntxhuav yog softer, tab sis suppuration tsim sai dua, thiab catgut tsis yog li ntawd mos thiab ruaj, tab sis nrog nws cov kev pheej hmoo ntawm suppuration yog. txo los ntawm 10 npaug.
