I-Hernia ithetha ukuba i-organ okanye i-tissue emzimbeni womntu ishiya indawo yayo yesiqhelo ye-anatomical kwaye ingene kwenye indawo nge-congenital okanye ifunyenwe indawo ebuthathaka, isiphene okanye umngxuma.. Umnatha wenziwa ukunyanga i-hernia.

Kwiminyaka yakutshanje, kunye nophuhliso olukhawulezayo lwesayensi yezinto, izixhobo ezahlukeneyo zokulungisa i-hernia zisetyenziswe ngokubanzi kwiklinikhi, eyenze utshintsho olusisiseko kunyango lwe-hernia. Okwangoku, ngokwezinto eziye zasetyenziswa ngokubanzi ekulungiseni i-hernia emhlabeni, i-meshes inokwahlulwa ibe ngamacandelo amabini: i-mesh engafunxayo, efana ne-polypropylene kunye ne-polyester, kunye ne-composite mesh.

Umnatha wepolyesteryaqanjwa ngo-1939 kwaye yeyona mesh yokuqala esetyenziswa ngokubanzi. Zisasetyenziswa ngoogqirha botyando namhlanje njengoko zibiza kakhulu kwaye kulula ukuzifumana. Nangona kunjalo, ngenxa yokuba umsonto we-polyester ukwisakhiwo se-fibrous, awulungile njenge-monofilament polypropylene mesh malunga nokumelana nosulelo. Ukudumba kunye nokusabela komzimba wangaphandle wezinto zepolyester zibaluleke kakhulu kuzo zonke iintlobo zemathiriyeli yemesh.

Polypropylene Meshilukwe ngeentsinga zepolypropylene kwaye inomaleko omnye wemesh. I-Polypropylene yeyona nto ikhethwayo yokulungisa iziphene zodonga lwesisu okwangoku. Iinzuzo zingezantsi.

1. Ithambile, imelana ngakumbi nokugoba kunye nokugotywa
2. Iyakwazi ukulungelelaniswa nobungakanani obufunekayo
3. Inempembelelo ecacileyo ngakumbi ekukhuthazeni ukwanda kwezicubu ze-fibrous, kwaye i-mesh aperture inkulu, eyenza ngakumbi ukukhula kwezicubu ze-fibrous kwaye ingena lula ngezicubu ezidibeneyo.
4. Ukusabela komzimba wangaphandle kunobulali, isigulane asinalo umzimba wangaphandle ocacileyo kunye nokungonwabi, kwaye unezinga eliphantsi kakhulu lokuphindaphinda kunye nenqanaba lobunzima.
5. Ukuxhathisa ngakumbi kusulelo, nakwizilonda ezosulelekileyo, izicubu zegranulation zisenokwanda kumnatha womnatha, ngaphandle kokudala ukubola kwemesh okanye ukwakheka kwe-sinus.
6. Amandla okuqina aphezulu
7. Ukungachatshazelwa ngamanzi kunye neekhemikhali ezininzi
8. Ukumelana nokushisa okuphezulu, kunokubiliswa kwaye kufakwe inzalo
9. Ixabiso eliphantsi

I-polypropylene mesh yeyona nto siyincoma kakhulu. Iintlobo ezi-3 zePolypropylene, ezinzima (80g / ㎡), eziqhelekileyo (60g / ㎡) kunye nokukhanya (40g / ㎡) ubunzima obunobukhulu obahlukeneyo bunokubonelelwa. Imilinganiselo ethandwa kakhulu yi-8 × 15 (cm) , 10 × 15). cm, 15 × 15 (cm), 15 × 20 (cm).

Umnatha owandisiweyo wePolytetrafluoroethyleneithambile ngakumbi kune-polyester kunye ne-polypropylene meshes.Akulula ukwenza i-adhesions xa udibana nezitho zesisu, kwaye ukusabela okuvuthayo okubangelwayo nako kulula kakhulu.

Umnatha odibeneyongumnatha oneentlobo ezi-2 okanye ngaphezulu zemathiriyeli. Inomsebenzi ongcono emva kokufunxa izibonelelo zezinto ezahlukeneyo. Umzekelo,

Umnatha wePolypropylene udityaniswe ne-E -PTFE imathiriyeli okanye iPolypropylene mesh edityaniswe nezinto ezinokufunxa.
