Hernia txhais tau hais tias ib qho khoom nruab nrog cev lossis cov ntaub so ntswg hauv tib neeg lub cev tawm ntawm nws txoj haujlwm anatomical ib txwm thiab nkag mus rau lwm qhov los ntawm lub hauv paus los yog tau txais qhov tsis muaj zog, qhov tsis zoo lossis qhov.. Lub mesh tau tsim los kho hernia.

Nyob rau hauv xyoo tas los no, nrog kev txhim kho sai ntawm cov ntaub ntawv tshawb fawb, ntau yam khoom siv kho hernia tau siv dav hauv kev kho mob, uas tau ua rau muaj kev hloov pauv tseem ceeb hauv kev kho mob hernia. Tam sim no, raws li cov ntaub ntawv uas tau siv dav hauv kev kho hernia hauv ntiaj teb, cov meshes tuaj yeem muab faib ua ob pawg: cov mesh uas tsis yog absorbable, xws li polypropylene thiab polyester, thiab composite mesh.

Polyester meshtau tsim nyob rau xyoo 1939 thiab nws yog thawj zaug siv cov khoom siv hluavtaws mesh. Lawv tseem siv los ntawm qee tus kws phais neeg niaj hnub no vim nws pheej yig heev thiab yooj yim tau txais. Txawm li cas los xij, vim tias cov xov paj polyester yog nyob rau hauv cov qauv fibrous, nws tsis zoo li monofilament polypropylene mesh raws li kev tiv thaiv kab mob. Cov o thiab txawv teb chaws lub cev cov tshuaj tiv thaiv ntawm cov ntaub ntawv polyester yog loj tshaj plaws ntawm tag nrho cov hom ntawm cov ntaub ntawv rau mesh.

Polypropylene Meshyog woven los ntawm polypropylene fibers thiab muaj ib txheej txheej mesh qauv. Polypropylene yog cov khoom siv kho kom zoo rau cov kab mob plab plab tam sim no. Qhov zoo yog raws li hauv qab no.

1. softer, ntau resistant rau dabtsi yog khoov thiab folding
2. Nws tuaj yeem hloov kho raws li qhov xav tau
3. Nws muaj qhov pom tseeb dua ntawm kev txhawb nqa cov ntaub so ntswg proliferation, thiab cov mesh aperture loj dua, uas yog qhov zoo dua rau kev loj hlob ntawm cov ntaub so ntswg thiab yooj yim nkag los ntawm cov ntaub so ntswg.
4. Lub cev txawv teb chaws cov tshuaj tiv thaiv yog mob me, tus neeg mob tsis muaj qhov pom tseeb txawv teb chaws lub cev thiab tsis xis nyob, thiab muaj tus nqi rov qab qis heev thiab muaj teeb meem.
5. Kev tiv thaiv ntau dua rau kev kis kab mob, txawm tias nyob rau hauv cov kab mob purulent, cov ntaub so ntswg granulation tseem tuaj yeem proliferate nyob rau hauv lub mesh ntawm lub mesh, tsis ua rau mesh corrosion los yog sinus tsim.
6. Siab zog tensile
7. Tsis cuam tshuam los ntawm dej thiab tshuaj lom neeg feem ntau
8. High kub kuj, tuaj yeem boiled thiab sterilized
9. Tus nqi pheej yig

Polypropylene mesh kuj yog qhov peb pom zoo tshaj plaws. 3 hom Polypropylene, hnyav (80g / ㎡), tsis tu ncua (60g / ㎡) thiab lub teeb (40g / ㎡) hauv qhov hnyav nrog qhov sib txawv tuaj yeem muab tau. Qhov loj tshaj plaws yog 8 × 15 (cm), 10 × 15 ( 15 × 15 (cm), 15 × 20 (cm).

Expanded Polytetrafluoroethylene meshyog mos dua polyester thiab polypropylene meshes.Nws tsis yog ib qho yooj yim rau tsim adhesions thaum nyob rau hauv kev sib cuag nrog lub plab hnyuv kab mob, thiab cov inflammatory tshwm sim los kuj yog lub lightest.

Composite meshyog lub mesh nrog 2 lossis ntau hom khoom. Nws muaj kev ua tau zoo dua tom qab absorbing qhov zoo ntawm cov khoom sib txawv. Piv txwv li,

Polypropylene mesh ua ke nrog E -PTFE cov ntaub ntawv los yog Polypropylene mesh ua ke nrog cov khoom absorbable.
