mankhwala

Hernia amatanthauza kuti chiwalo kapena minofu m'thupi la munthu imasiya malo ake achibadwa ndikulowa gawo lina kudzera mu congenital kapena kupeza chofooka mfundo, chilema kapena dzenje.. Maunawa anapangidwa kuti azichiza chophukacho.

M'zaka zaposachedwa, ndi chitukuko chofulumira cha sayansi yazinthu, zida zosiyanasiyana zokonzera chophukacho zakhala zikugwiritsidwa ntchito kwambiri pazachipatala, zomwe zasintha kwambiri pochiza chophukacho.Pakalipano, malinga ndi zipangizo zomwe zakhala zikugwiritsidwa ntchito kwambiri pokonza chophukacho padziko lapansi, ma meshes amatha kugawidwa m'magulu awiri: mauna osasunthika, monga polypropylene ndi poliyesitala, ndi mauna ophatikizana.

Polyester meshidapangidwa mu 1939 ndipo ndi mesh yoyamba kugwiritsidwa ntchito kwambiri.Amagwiritsidwabe ntchito ndi madokotala ena ochita opaleshoni masiku ano chifukwa ndi otchipa kwambiri komanso osavuta kuwapeza.Komabe, chifukwa ulusi wa poliyesitala uli mumtundu wa ulusi, suli wabwino ngati mauna a monofilament polypropylene polimbana ndi matenda.Kutupa ndi machitidwe akunja azinthu za polyester ndizowopsa kwambiri pakati pa mitundu yonse yazinthu zama mesh.

Polypropylene Meshamalukidwa kuchokera ku ulusi wa polypropylene ndipo ali ndi gawo limodzi la mesh.Polypropylene ndiye chinthu chomwe chimakondedwa kwambiri pakukonza zopumira zam'mimba pakadali pano.Ubwino ndi monga pansipa.

1. Yofewa, yosamva kupindika ndi kupindika
2. Ikhoza kukhala yogwirizana ndi kukula kofunikira
3. Zimakhala ndi zotsatira zoonekeratu pakulimbikitsa kukula kwa minofu ya fibrous, ndipo khomo la ma mesh ndilokulirapo, lomwe limathandizira kukula kwa minofu ya fibrous ndipo imalowa mosavuta ndi minofu yolumikizana.
4. Maonekedwe a thupi lachilendo ndi ofatsa, wodwala alibe thupi lodziwikiratu lachilendo ndi kusamva bwino, ndipo ali ndi chiwerengero chochepa kwambiri chobwerezabwereza komanso kuchuluka kwa zovuta.
5. Kusagonjetsedwa ndi matenda, ngakhale m'mabala omwe ali ndi kachilombo ka purulent, minofu ya granulation imatha kuchulukirabe muukonde wa mauna, popanda kuchititsa dzimbiri kapena kupangika kwa sinus.
6. Mphamvu zapamwamba kwambiri
7. Osakhudzidwa ndi madzi ndi mankhwala ambiri
8. Kutentha kwakukulu kukana, kukhoza kuwiritsa ndi kusakaniza
9. Zotsika mtengo

Polypropylene mesh ndiyenso timalimbikitsa kwambiri.Mitundu ya 3 ya Polypropylene, yolemera (80g / ㎡), yokhazikika (60g / ㎡) ndi yopepuka (40g / ㎡) kulemera kwake ndi miyeso yosiyana ingaperekedwe. Miyeso yotchuka kwambiri ndi 8 × 15 (cm) , 10 × 15). cm, 15 × 15 (masentimita), 15 × 20 (masentimita).

Wowonjezera Polytetrafluoroethylene meshndizofewa kwambiri kuposa ma polyester ndi polypropylene meshes.Sizophweka kupanga zomata pamene zimagwirizana ndi ziwalo za m'mimba, ndipo kutupa komwe kumayambitsa kumakhalanso kopepuka.

Masamba a kompositindi mauna okhala ndi mitundu iwiri kapena kupitilira apo.Ili ndi ntchito yabwino pambuyo potengera ubwino wa zipangizo zosiyanasiyana.Mwachitsanzo,

Ma mesh a polypropylene ophatikizidwa ndi E -PTFE zakuthupi kapena mauna a Polypropylene kuphatikiza ndi zinthu zomwe zimatha kuyamwa.
