Cov ntaub ntawv zoo tshaj plaws rau kev phais plawv

Kev phais plawv yog ib qho nyuaj uas yuav tsum tau muaj cov ntaub ntawv raug thiab txhim khu kev qha los xyuas kom cov neeg mob tau txais txiaj ntsig zoo. Ntawm cov ntaub ntawv no, sutures ua lub luag haujlwm tseem ceeb hauv kev tswj xyuas kev ncaj ncees ntawm kev kho phais, tshwj xeeb tshaj yog nyob rau hauv cov txheej txheem me me uas muaj cov hlab ntsha thiab lub plawv. Hauv tsab xov xwm no, peb yuav tshawb nrhiav cov ntaub ntawv zoo tshaj plaws rau kev phais plawv, tsom mus rau lawv cov khoom, cov txiaj ntsig, thiab cov kev siv tshwj xeeb los pab cov kws kho mob xaiv cov kev xaiv.

Vim Li Cas Xaiv Txoj Cai Suture Material Matters

Hauv kev phais plawv, xaiv cov khoom siv suture tsim nyog yog qhov tseem ceeb vim tias nws cuam tshuam ncaj qha rau kev ua tiav ntawm kev ua haujlwm thiab kev kho kom zoo. Sutures yuav tsum muaj zog txaus los tuav cov ntaub so ntswg ua ke nyob rau hauv siab thaum tseem maj mam kom tsis txhob ua kev puas tsuaj. Tsis tas li ntawd, lawv yuav tsum muaj cov yam ntxwv zoo heev, cov tshuaj tiv thaiv cov ntaub so ntswg tsawg, thiab kev ruaj ntseg zoo los tiv thaiv cov teeb meem.

Sab saum toj Suture Materials rau cov txheej txheem plawv

1.Polyester Sutures

Polyester yog cov khoom siv hluavtaws, uas tsis yog-absorbable suture siv dav hauv kev phais plawv. Nws muaj lub zog tensile siab thiab zoo heev tuav cov khoom, ua rau nws zoo tagnrho rau vascular anastomosis thiab valve hloov cov txheej txheem. Polyester sutures tshwj xeeb tshaj yog nyiam rau lawv cov kav ntev thiab cov ntaub so ntswg tsawg, txo qhov kev pheej hmoo ntawm cov lus teb inflammatory. Piv txwv li, nyob rau hauv coronary artery bypass grafting (CABG), polyester sutures pab kom muaj kev ruaj ntseg thiab ntev-ntev kev sib txuas ntawm grafts thiab haiv neeg cov hlab ntsha.

2.Polypropylene Sutures

Polypropylene yog lwm qhov kev xaiv nrov rau kev siv cov hlab plawv, paub txog nws yooj yim thiab biocompatibility. Nws kuj yog ib yam khoom uas tsis yog-absorbable, uas muaj txiaj ntsig zoo hauv kev phais mob uas yuav tsum tau siv cov ntaub so ntswg ntev. Nws lub ntsej muag du txo cov nqaij ntshiv thaum lub sijhawm dhau mus, ua rau nws tsim nyog rau kev kho cov hlab ntsha me. Polypropylene qhov tsis kam tiv thaiv kab mob thiab cov ntaub so ntswg qis ua rau nws nyiam suture rau cov txheej txheem xws li kho aortic aneurysm.

3.ePTFE (Expanded Polytetrafluoroethylene) Sutures

ePTFE sutures yog heev resistant rau deformation, ua rau lawv yog ib qho kev xaiv zoo heev rau kev kho mob plawv siab. Lawv muaj txiaj ntsig tshwj xeeb hauv kev phais nrog cov khoom siv hluavtaws, vim lawv muab cov ntaub so ntswg zoo sib xws thiab kev sib txhuam qis. Cov kws phais mob feem ntau xaiv ePTFE rau nws lub peev xwm los daws cov vascular anastomoses tsis tau txiav los ntawm cov hlab ntsha phab ntsa, yog li tiv thaiv cov teeb meem tom qab phais xws li suture kab los ntshav.

Absorbable vs. Non-Absorbable Sutures

Kev nkag siab qhov sib txawv ntawm absorbable thiab non-absorbable sutures yog qhov tseem ceeb rau kev xaiv cov khoom siv rau cov txheej txheem plawv.

•Absorbable Sutures:Cov sutures maj mam zom hauv lub cev thiab yog absorbed dhau sijhawm. Lawv feem ntau yog siv rau hauv cov xwm txheej uas qhov kev pab cuam lub qhov txhab ib ntus txaus. Txawm li cas los xij, hauv kev phais plawv, cov sutures absorbable tsis tshua muaj vim tias lawv tsis muab kev txhawb nqa mus tas li xav tau rau kev kho qhov tseem ceeb.

•Tsis-absorbable Sutures:Raws li lub npe qhia, cov sutures no yog tsim los nyob rau hauv lub cev mus tas li los yog txog thaum lawv raug tshem tawm. Non-absorbable sutures zoo li polyester, polypropylene, thiab ePTFE yog cov qauv kev xaiv rau cov txheej txheem plawv, muab kev ruaj ntseg mus ntev thiab txo qhov kev pheej hmoo ntawm aneurysmal dilatation.

Lub luag haujlwm ntawm Suture Size hauv Kev Kho Mob plawv

Xaiv qhov loj suture yog qhov tseem ceeb sib npaug li cov khoom nws tus kheej. Hauv kev phais plawv, qhov ntau thiab tsawg suture (xws li 6-0 lossis 7-0) feem ntau yog siv vim tias lawv txo cov nqaij ntshiv thiab txhim kho qhov tseeb, tshwj xeeb tshaj yog nyob rau hauv cov qauv vascular ilv. Txawm li cas los xij, qhov loj dua tuaj yeem siv rau hauv thaj chaw uas xav tau lub zog ntxiv thiab kev txhawb nqa, zoo li hauv kev kho aortic.

Txoj Kev Kawm: Ua tiav hauv Coronary Artery Bypass Grafting (CABG)

Ib txoj kev tshawb fawb nrog rau cov neeg mob CABG tau pom qhov ua tau zoo ntawm polyester sutures hauv kev ua tiav cov grafts zoo. Cov kws phais tau pom tias polyester lub siab tensile lub zog thiab cov ntaub so ntswg tsawg tsawg tau ua rau txo qis ntawm cov teeb meem tom qab kev ua haujlwm thiab txhim kho tag nrho cov graft patency. Cov ntaub ntawv pov thawj no qhia txog cov khoom tsim nyog rau cov txheej txheem tseem ceeb ntawm cov hlab plawv qhov uas cov sutures ruaj thiab txhim khu kev qha yog qhov tseem ceeb.

Cov lus qhia rau kev tuav pov hwm kev ncaj ncees

Kev tuav cov sutures kom raug thaum phais tuaj yeem cuam tshuam qhov tshwm sim. Cov kws phais yuav tsum zam kom tsis txhob muaj qhov nro ntau dhau thaum khi pob caus, vim qhov no tuaj yeem ua rau cov ntaub so ntswg puas lossis suture tawg. Tsis tas li ntawd, ua kom muaj kev tuav tsawg kawg nkaus thiab siv cov tswv yim tsim nyog rau kev khi cov pob qij txha tuaj yeem pab tswj cov txheej txheem kev ncaj ncees ntawm cov sutures, txhim kho lawv cov kev ua tau zoo thaum lub sijhawm kho.

Lub neej yav tom ntej ntawm Suture Materials nyob rau hauv Cardiovascular Surgery

Kev nce qib hauv kev siv tshuab suture tau hloov zuj zus mus tas li, nrog rau kev tsom mus rau kev txhim kho cov neeg mob kev nyab xeeb thiab txhim kho qhov tshwm sim ntawm kev phais. Kev tsim kho tshiab xws li cov tshuaj tiv thaiv kab mob thiab cov kab mob bioactive sutures uas txhawb kev kho mob tam sim no tau tshawb nrhiav hauv cov ntawv thov plawv. Cov kev txhim kho no txhawm rau txo qis tus kab mob thiab txhawb kev sib koom ua ke zoo dua nrog cov ntaub so ntswg, muab cov txiaj ntsig zoo siab rau yav tom ntej ntawm kev phais plawv.

Xaiv cov khoom siv suture zoo rau kev phais plawv yog qhov kev txiav txim siab tseem ceeb uas tuaj yeem cuam tshuam cov txiaj ntsig ntawm tus neeg mob. Cov ntaub ntawv zoo li polyester, polypropylene, thiab ePTFE muaj lub zog zoo, ua haujlwm ntev, thiab cov ntaub so ntswg tsawg, ua rau lawv zoo tagnrho rau cov txheej txheem mob plawv. Los ntawm kev nkag siab txog cov yam ntxwv tshwj xeeb ntawm cov sutures thiab xav txog yam xws li suture loj thiab tuav cov tswv yim, cov kws phais tuaj yeem ua cov kev xaiv paub uas txhim kho kev phais kom zoo thiab txhawb kev kho kom zoo.

Rau cov kws kho mob nrhiav kev txhim kho lawv cov txheej txheem phais thiab cov txiaj ntsig, kev nqis peev sijhawm los xaiv cov khoom siv suture tsim nyog yog qhov tseem ceeb. Txawm hais tias koj tab tom cuam tshuam nrog kev kho niaj hnub lossis kev txhim kho vascular, txoj cai suture tuaj yeem ua rau txhua qhov sib txawv.
