I-Hernia isho ukuthi isitho noma izicubu emzimbeni womuntu ishiya indawo yayo evamile ye-anatomical bese ingena kwenye ingxenye ngephuzu elibuthakathaka lokuzalwa noma elitholiwe, ukukhubazeka noma imbobo.. I-mesh yasungulwa ukwelapha i-hernia.

Eminyakeni yamuva, ngokuthuthuka okusheshayo kwesayensi yezinto zokwakha, izinto ezihlukahlukene zokulungisa i-hernia ziye zasetshenziswa kabanzi emisebenzini yomtholampilo, okwenze ushintsho oluyisisekelo ekwelapheni i-hernia. Njengamanje, ngokusho kwezinto ezisetshenziswe kabanzi ekulungiseni i-hernia emhlabeni, ama-meshes angahlukaniswa ngezigaba ezimbili: i-mesh engabambeki, njenge-polypropylene ne-polyester, ne-composite mesh.

I-polyester meshyasungulwa ngo-1939 futhi ingeyokuqala esetshenziswa kabanzi i-synthetic material mesh. Zisasetshenziswa abanye odokotela abahlinzayo namuhla njengoba ishibhile futhi kulula ukuzithola. Kodwa-ke, ngenxa yokuthi intambo ye-polyester isesimweni esine-fibrous, ayilungile njenge-monofilament polypropylene mesh mayelana nokumelana nokutheleleka. Ukuvuvukala nokusabela komzimba wangaphandle wezinto ze-polyester kubi kakhulu kuzo zonke izinhlobo zezinto ze-mesh.

I-Polypropylene Meshyalukwa ngemicu ye-polypropylene futhi inohlaka olulodwa lwe-mesh. I-Polypropylene iyinto ekhethwayo yokulungisa amaphutha odongeni lwesisu okwamanje. Izinzuzo zinjengoba ngezansi.

1. Ithambile, imelana kakhulu nokugoba nokugoqa
2. Ingenziwa ehambisana nosayizi odingekayo
3. Kunomphumela osobala kakhulu ekukhuthazeni ukwanda kwezicubu ze-fibrous, futhi imbobo ye-mesh inkulu, esiza kakhulu ekukhuleni kwezicubu ze-fibrous futhi ingena kalula yi-connective tissue.
4. Ukusabela komzimba wangaphandle kuthambile, isiguli asinawo umzimba wangaphandle osobala kanye nokuphatheka kabi, futhi sinezinga eliphansi kakhulu lokuphindaphinda kanye nezinga lenkinga.
5. Ukumelana kakhulu nokutheleleka, ngisho nakumanxeba anegciwane le-purulent, izicubu ze-granulation zisenganda emithanjeni ye-mesh, ngaphandle kokudala ukugqwala kwe-mesh noma ukwakheka kwe-sinus.
6. Amandla okuqina aphakeme
7. Akuthintwa amanzi kanye namakhemikhali amaningi
8. Ukumelana nokushisa okuphezulu, kungabiliswa futhi kufakwe inzalo
9. Kushibhile uma kuqhathaniswa

I-polypropylene mesh yiyona futhi esiyincoma kakhulu. Izinhlobo ezi-3 zePolypropylene, esindayo (80g/㎡), ejwayelekile (60g/㎡) futhi ilula (40g/㎡) enesisindo esinobukhulu obuhlukene inganikezwa. Ubukhulu obudume kakhulu bungu-8×15(cm),10×15). cm, 15 × 15 (cm), 15 × 20 (cm).

I-Polytetrafluoroethylene mesh enwetshiweithambile kakhulu kune-polyester ne-polypropylene meshes.Akulula ukwenza ukunamathela lapho uthintana nezitho zesisu, futhi ukusabela kokuvuvukala okubangelwa nakho kulula kakhulu.

I-composite meshiyinetha elinezinhlobo zezinto ezi-2 noma ngaphezulu. Isebenza kangcono ngemuva kokumunca izinzuzo zezinto ezahlukahlukene. Ngokwesibonelo,

I-Polypropylene mesh ehlanganiswe ne-E -PTFE impahla noma i-Polypropylene mesh ehlanganiswe nezinto ezimuncayo.
