Absorbable suture khoom. Phais suture

Thaum lub sij hawm kev phais kev pab yog tsim nyog mus cuag cov ntaub so ntswg, cov hlab ntsha. Sutures phais underwent ib tug tej yam evolution, thiab niaj hnub no lawv muaj ib tug xov tooj ntawm tej thaj chaw uas txhawb sai kho ntawm cov qhov txhab. Niaj hnub nimno cov tshuaj tau muab rau tus account thiab cov hniav zoo nkauj sab: lub nqaws yog tsawg hnov, thiab tej zaum kuj los ntawm lawv, thiab tsis muaj ib tug kab nyob.

Cov yam ntxwv ntawm cov ntaub ntawv rau crosslinking

Suture khoom yuav tsum muaj ib tug xov tooj ntawm tej kev txawj ntse. Ua ntej, tej khoom yuav tsum tsis txhob yuav lom, ua kom ua xua. Lwm tsim nyog zoo - kuj mus kom tsis muaj menyuam, vim hais tias nws yog qhov uas tsis pathogens yog qho tseem ceeb heev thaum lub sij hawm kev phais. Thiab, ntawm chav kawm, lub suture khoom yuav tsum muaj zog, tsis txhob raug mob cov ntaub so ntswg los ntawm kev uas nws kis tau. Tseem ceeb thiab nws cov elasticity thiab muaj peev xwm mus tsim ntshav. Tag nrho tej ntaub ntawv yuav siv rau hauv daim ntawm ib tug xov los yog tsim nyob rau ntawm ob peb (sib ntswg, braiding). Nyob rau hauv cov ntaub ntawv tus muaj peev xwm mus biodegradation, lub kev faib ntawm lub suture yog: absorbable suture, maj mam absorbable, thiab cov neeg uas tsis yaj nyob hauv tag nrho cov. Tsis tas li ntawd lub caij nyob rau hauv kev phais yuav ua tau ob yam thiab hluavtaws keeb kwm.

Ntaub ntawv uas tsis yaj

Cov ntaub ntawv tau siv ua ntej lub advent ntawm ntau niaj hnub counterparts. Txawm li cas los, lawv yog tam sim no dav siv nyob rau hauv cov neeg mob thaum nws yog tsim nyog los tau ib tug muaj zog thiab txhim khu kev qha kev twb kev txuas. Nyob rau hauv cov ntaub ntawv no, cov ntaub rau ib ntev lub sij hawm yuav tsum tau muaj nyob rau hauv ib tug zoo xws li cov leeg. Qhov no muaj xws li qeb txhob lo lo ntxhuav threads (kuj absorbable txij li thaum ua imperceptible tom qab ib tug ob peb xyoos), polyester, polypropylene, polyvinyl, hlau khoom siv, cov khoom sib khawb. Txhob lo lo ntxhuav muaj ib tug txaus loj zog. Qhov no xov yog heev yooj yim mus muab, mus khi pob caus ntawd. Nws yog feem ntau pom cov tshuaj tiv thaiv nyob rau hauv cov ntaub so ntswg. Feem ntau xws suture khoom siv nyob rau hauv Ophthalmology, yas phais, ua hauj lwm nyob rau hauv txoj hnyuv kabmob. Los ntawm inert filaments xws li polypropylene. Vim hais tias ntawm nws cov high zog yog siv rau kev thov sob kho ntau yam ntsiab. Cov hlau hlau yog ua los ntawm steel hlau, nws yuav siv tau nyob rau hauv kaus siab feem thiab m. P.

Dacron phais

Phais suture khoom raws li polyester tau undoubted zoo: siab zog, tuav cov khoom nyob rau theem. Nyob rau hauv tas li ntawd, nws heev tsis tshua muaj ua rau tshua nyob hauv cov ntaub so ntswg. Feem ntau nws ntawm ob peb hom: woven, braided, coated nrog fluororubber. Tus nqi ntawm xws li ib filament yog kuj tsis tshua muaj. Feem ntau, xws li ib tug suture yog siv thaum lub sij hawm prosthetic ntaub so ntswg, cov neeg ua haujlwm rau hauv lub nyuaj kho chaw, raws li zoo raws li qhov chaw nyob qhov twg muaj ib tug tsis tu ncua nro. Txawm li cas los, muaj ib co drawbacks. Ua nyob rau hauv lub cev mus tas li, xws threads yuav ua rau o.

Cov yam ntxwv ntawm ib tug cov ntaub ntawv uas muaj peev xwm mus disperse. catgut

Tshuaj ntawm no hom yuav ua tau tej yam ntuj tso los yog hluavtaws. Yuav kom nqa tej yam ntuj tso catgut. Qhov no phais suture khoom tsim los ntawm cov me me hnyuv tsiaj (noj qab nyob zoo), uas yog tiav nyob rau hauv ib tug tshwj xeeb txoj kev. Chiv, xws li ib tug cov ntaub ntawv uas muaj lub zog txaus, tab sis nws yog sai poob. Rau ib lub lim tiam los yog ob tug ntawm nws cov indices yog txo los ntawm ib nrab. Yuav kom resorption lub sij hawm ntau zog me ntsis los ntawm kev kho mob nrog catgut chromium ntsev. Qhov no manipulation tsub kom nyias mus nyias lub sij hawm nyob rau hauv ib nrab. Nws yog ib qho tseem ceeb rau koj nco ntsoov qhov tseeb hais tias xws li suture absorbed txawv nyob rau cov ntaub so ntswg nyob rau hauv uas nws tau muab tso rau, thiab cov kev siv ntawm cov ntshav mov rau ntawm qhov chaw, tus neeg yam ntxwv ntawm tus kab mob. Qhov tsis zoo yog cov rigidity thiab xov, raws li zoo raws li lub tseem tsis haum. Main daim ntaub ntawv - Gynecology, urology, kev phais rau cov pa thiab digestive kabmob, qhov txhab kaw.

Synthetic absorbable sutures

Qhov no muaj xws li hom tshuaj uas muaj kev pom kev zog. Nyob rau hauv lawv daim ntawv thov yog ib qho yooj yim rau koj twv seb lub sij hawm ntawm tsis muaj zog. Nyob rau hauv tas li ntawd, cov yarns yog ib qho yooj yim mus siv, lawv yog cov heev muaj zog. Lwm meej plus - lub inertia thiab tsis muaj kev tsis haum tshuaj loj. Ib tug ntau yam - polyglycolic absorbable suture khoom. Nws yog yus muaj los ntawm siab durability thiab muaj peev xwm ntawm ceev ib qho tseem ceeb mob zoo lub sij hawm. Dexon - ib qho ntawm feem ntau cov ntaub ntawv siv nyob rau hauv kev phais raws li nyob rau hauv Gynecology, urology. Tej hluavtaws cov ntaub ntawv muaj ib qho keeb kwm. Lawv yog cov - polymers ntawm lactic acid. Tom qab cov xov tau txais mus rau hauv cov ntaub so ntswg tshwm sim hydrolysis txheej txheem. Thaum kawm tiav ntawm tag nrho cov tshuaj tshua suture nws decomposes rau dej lwg me me thiab cov pa roj carbon dioxide. Qhov tseem nquag siv hluavtaws absorbable suture rau cov nqaij mos thiab mob plab pleural kab noj hniav. Nyob rau hauv cov chaw no, cov lwm lub sij hawm yog los ntawm ib lub lim tiam rau ib lub hlis, thaum nws coincides nrog indicators, As ntawm txo lub dag lub zog ntawm cov khoom.

Vicryl - suture kev koom cov ntaub so ntswg

Rau tebchaw ntawm nqaij mos mos thiab qhov chaw uas tsis yuav tsum tau ntev-lub sij hawm nyem, siv niaj hnub cov ntaub ntawv uas vicryl. Nws muaj ib tug hluavtaws keeb kwm thiab yog muaj li ntawm glycolide thiab L-lactide. Cov ntaub so ntswg tshua thaum siv tsawg li tsawg, lub dag lub zog yog txo tom qab 4 lub lis piam. Sau kom tiav nyias mus nyias nyob rau hauv ib tug kab tsiaj txhuv yuav siv sij hawm qhov chaw los ntawm hydrolysis tom qab 50-80 hnub. Thov xws yarns thiab nyob rau hauv Ophthalmology thiab Gynecology. Tab sis cov cheeb tsam nyob rau hauv uas nws siv yog tsis tsim nyog - neurosurgery thiab lub plawv phais. Vicryl - suture khoom uas yuav tau nkag rau hauv unpainted daim ntawv no, thiab muaj ib tug liab doog xim. Threads nyob txawv thickness thiab ntev. Cheebtsam yuav muaj xws li ib tug stainless steel koob.

Cia ntawm phais sutures

Yuav kom xov khaws lawv lub zog, nws yog ib qho tseem ceeb ua raws li qhov tseeb kub. Sutures nyob rau hauv phais poob lub zog thaum muab cia rau hauv ib tug kub siab tshaj 30º C los yog tsis zoo indicators, As. Yog hais tias cov xov tau raug tshem tawm los ntawm lub ntim, tab sis tsis siv, nws yuav tsum tau muab pov tseg. Nws yog ib qho tseem ceeb los mus saib xyuas thiab hnub tas zim txwv. Raws li lawv lub zog tom qab ib tug ob peb hloov. Hu nrog dej thiab yog heev undesirable. Tsis txhob pheej rov qab ua kom tsis muaj menyuam txoj kev lub suture.
