I-Endo Linear Cutter Stapler: Amasiko okusebenzisa kwezinto zokuchitha

Ukusebenza kwe-Disposable Endo Linear Cutter Stapler: Imisebenzi Yezibalo Zombili Ne-Response Yomlando

Ukusebenza kwezibalo zokuphinda kabili: ukubeka umlando phakathi, ukudala izistaple, nokuthintela ngokulineyile

I-stapler yokusika ye-endo linear edonswayo yenza ukulandelana okuyizigaba ezintathu okuqondiswe ngesikhathi esifanele okuguqula ukuvalwa ngesandla kube i-anastomosis ethembekile. Ukuvalwa komhlathi kokuqala kusetshenziswa ukucindezelwa okulawulwayo, okufanayo kulo lonke izicubu kunciphisa ubukhulu nokuthutha uketshezi oluphakathi ukuze kuzinze indawo okuhloswe kuyo futhi kunciphise ukopha. Lapho sekutholakale ukuphakama okuphelele kokuvala, umshini wokudubula usebenza kanyekanye ngemigqa emibili yezingqimba ze-titanium ezimise u-B ezinhlangothini zombili zomugqa wokucutha ohlosiwe. Imilenze yangaphakathi ye-stapler iyashintsha ngokumelene ne-anvil, ibopheleke ngendlela eqinisekile, ezishaya ngokwayo egcina i-hemostasis ngisho nangaphansi kokucindezeleka kwangemva kokuhlinzwa. Ngokushesha ngemva kokwakheka kwe-staple, ibhande elihlanganisiwe elingasetshenziswa kanye lihamba phakathi kwemigqa emibili ye-staple, linqume izicubu ngendlela ehlanzekile. Umugqa ophelele oshiya umngcele omncane, onemigqa emibili kuzo zombili izingxenye eziseduze nezikude, okuqinisekisa ukuvalwa kwesilonda ngokushesha.

Le-ntshiselwano leli lekuphatha izinyathelo zokukhupha kanye nokusutha ngokwahlukile, lekuphatha ukuguqula amashini, kanye lekuphatha isikhathi esisodwa sokusebenzisa izinto ezihlukene. Ngokugcina, ukufaka amashini kanye nokukhupha ngonye yendlela eyingqayile, lekhetho lelisobala lekuphatha ukubulawa kwamaphakathi, likhumbula ukuziphatha kwe-microvascular kwi-staple line, kanye likhansela ukuthi kungabi nesibopho sokuhlanza kumsebenzi wokusebenzisa izinto ezihlukene. Iyenzelwa yonke le ndlela ngaphansi kwe-trocar esine izingxenye ze-12-mm noma ze-15-mm—kuyisifundo esihle kuma-procedure e-laparoscopic kanye ne-thoracoscopic apho ukuphatha kanye nokushaya kuyisifundo esibalulekile. Ukuphatha kwe-biomechanical kuyisifundo esifanayo kuyidinga ukuthi i-cartridge, i-anvil, kanye ne-knife channel liyahlukane ngokucophelela, kanye nokuthi umsebenzisi ayaphatha ngokucophelela—konke lokhu kuchazwa ngokusebenzisa lekhetho lelayisebenziswa kuphela umsithi wokuphatha ukuthi akukho kuchazwa ngokusebenzisa kabusha.

Ukuhlukana kwe-sibopho sokugcina kanye nezintlobo zezinto zokusebenzisa kuziphatha kwe-staple line kanye nokuthi kungabi nesibopho sokuhlukanisa

Isikhathi sokugcina nokubhindezela kwesifunda kusobala kakhulu ekuthinteni ubukhulu bekuphakanyiswa kwezindlela zokugcina. Uma isifunda sibhindezele kakhulu noma sifuna isikhathi esincane sokugcina, akasakhi isiphakamiso esigcwele. Uma kugcinwa ngaphansi kwezimali, izinyawo zezindlela zokugcina zingabhalwa ngokuphansi, okongena emisakhiweni yokuvula kwezinyawo noma ukungafani kwezindlela zokugcina. Ngaphandle kwalokho, uma kugcinwa ngaphezulu kwezimali noma kusetyenziswa isikhumba esinganayo ubukhulu obukhulu bokugcina, kufa amavashele omkhulu, okubangela ubukhohlwa kwezindawo futhi ukufa kwezifunda—okongena emisakhiweni yokuvula kwezindlela zokugcina ngokushesha.

Amagida wokusebenza kwezindlela zokugcina ayasho ukuthi kufanele kugcinwe ngaphambi kokugcina ngamasikili angu-15–30 ukuze isifunda sibhindezele ngokuphelele futhi amanzi asondele, okuhlela ukuthi izindlela zokugcina ziyakhiwa ngokuphelele. Ukukhetha ubukhulu bekuzindlela zokugcina—kubizwa ngokujwayelekile ngu-2.5 mm, 3.5 mm, noma 4.8 mm—kufanele kuchazwe ngokubhindezelwa kwebukhulu besifunda. emva ukugcina. Amakartrijhi amaningi asezinga eliphezulu aqondisa izindikayitha eziyisibonelo sokubhala ngomthwalo wokugcina.
