Xa kuziwa kuqhaqho lwe-laparoscopic, abantu abaqhelekanga.Ngokuqhelekileyo, utyando lwenziwa kwisigxina sesigulane ngokusebenzisa i-2-3 encinci ye-1 cm.Injongo ephambili ye-trocar ye-laparoscopic elahlayo kwi-laparoscopic utyando kukungena.Udonga olugcweleyo lwesisu luseka umjelo phakathi kwehlabathi langaphandle kunye nomgodi wesisu, okuvumela izixhobo zotyando ukuba zingene kwisigxina sesisu ngokusebenzisa umkhono we-trocar ukugqiba inkqubo yotyando kunye nokufezekisa injongo efanayo nokuhlinzwa okuvulekileyo kwendabuko.I-trocar elahlayo ye-laparoscopy iqukethe i-cannula ye-puncture kunye ne-puncture core.Umsebenzi oyintloko we-puncture core kukungena kwindonga yesisu kunye ne-trocar cannula kwaye ushiye i-puncture cannula kwindonga yesisu.Umsebenzi oyintloko we-puncture cannula kukuvumela izixhobo ezahlukeneyo zotyando ukuba zingene kwisigxina sesisu, ukuze ugqirha akwazi ukwenza utyando kwaye agqibe umsebenzi wotyando.
Iimpawu kunye neenzuzo zeiitrocars ze-laparoscopic ezilahlwayo
1 Ukuhlukana kwamacala amabini ekupheleni kwentloko ye-puncture core
Ngokutsho kohlalutyo lweenkcukacha-manani zengxelo, iingxaki ezininzi zokubhoboza zibangelwa usulelo, ukopha, ukubhoboza i-hernia kunye nomonakalo wezicubu.
Intloko ye-puncture elahlayo yokusetyenziswa kwe-laparoscopic i-cone-shaped, ithatha indlela ye-blunt dissection ngaphandle kwemela, kwaye ithatha indawo yezicubu zokusika ngezicubu ezahlulayo.Ukunciphisa umonakalo kudonga lwesisu kunye nemithambo yegazi, kwaye unciphise umonakalo we-fascia malunga ne-40% kunye nokubunjwa kwe-puncture hernia ngaphezu kwe-80% xa kuthelekiswa ne-trocar ngemela.Ngokusebenzisa i-endoscope, yonke inkqubo yokuhlatywa kwendonga yesisu inokulawulwa ngokuthe ngqo ukuphepha umonakalo kwizicubu zesisu , Inokugcina ixesha lokusebenza kunye nokunciphisa intlungu yokusebenza.
2 Faka isingxobo sentambo yentsimbi yangaphandle
Intambo yangaphandle ye-barbed isetyenziswe kumphezulu we-trocar sheath elahlayo ukwandisa ukulungiswa kodonga lwesisu.Xa i-core puncture ikhutshwe, amandla ayanda, anokuphucula ukulungiswa kodonga lwesisu malunga ne-90%.
3 45° Ukuvulwa kwe-Chamfered kwincam yesingxobo
Incam ye-trocar sheath elahlayo yokusetyenziswa kwe-laparoscopic ivulekile kwi-bevel ye-45 °, eququzelela ukungena kwesampuli kwi-sheath kwaye ishiya indawo yokuguqulwa kwesixhobo.
4 .Gqibezela iinkcukacha zemodeli
Iitrocars ezilahlayo zokusetyenziswa kwe-laparoscopic zineenkcazo ezahlukeneyo: i-diameter yangaphakathi 5.5mm, 10.5mm, 12.5mm, njl.
Lilonke, i-trocar elahlayo yotyando lwe-laparoscopic oluncinci oluhlaselayo inokunciphisa ukulahleka kwegazi lesigulana, yenze isigulana sichache ngokukhawuleza, senze ixesha lotyando libe lifutshane, kwaye yenze isigulana sibe ngumxhamli wotyando lwesisu olungephi.
