Kuchuluka kwa ntchito: amagwiritsidwa ntchito poboola minofu ya m'mimba ya munthu pa laparoscopy ndi opaleshoni kukhazikitsa njira yogwirira ntchito ya opaleshoni ya m'mimba.
1.1 mafotokozedwe ndi chitsanzo
Mafotokozedwe ndi zitsanzo za chipangizo cha laparoscopic puncture chotayika chimagawidwa m'mitundu inayi: mtundu A, mtundu wa B, mtundu wa C ndi mtundu wa D molingana ndi kukula kwa manja obowola ndi mawonekedwe a puncture cone, monga momwe tawonetsera mu Gulu 1;Malingana ndi njira yoyikamo, imagawidwa kukhala phukusi limodzi ndi suti.
Table 1 specifications and model of disposable laparoscopic puncture device: mm
1.2 mafotokozedwe ndi mafotokozedwe agawo lachitsanzo
1.3 kapangidwe kazinthu
1.3.1 kapangidwe kazinthu
The disposable puncture chipangizo cha laparoscopy wapangidwa puncture kolona, puncture manja, mpweya jekeseni valavu, valavu tsamwitsa, kusindikiza kapu, kusindikiza mphete, etc. Njira ndi Converter.Kapangidwe kazinthu kameneka kakuwonetsedwa mu Chithunzi 1.
1. Puncture chulung 2 Puncture cannula 3 jekeseni wa gasi valavu 4 Choke 5 Chosindikizira 6 Chosindikizira mphete 7 chosinthira
1.3.2 zinthu zikuchokera mbali zazikulu za mankhwala
Zomwe zili m'zigawo zazikulu za chipangizo cha laparoscopic puncture cha mankhwalawa chikuwonetsedwa mu Gulu 2 pansipa:
2.1 miyeso
Kukula kwa chinthucho kuyenera kutsatira zomwe zili mu Gulu 1.
2.2 mawonekedwe
Chogulitsacho chidzakhala chophwanyika komanso chosalala popanda burrs, pores, ming'alu, grooves ndi sinter zomwe zingathe kudziwika ndi maso.
2.3 kusinthasintha
Vavu ya jekeseni wa gasi ndi valavu yotsamwitsa ya chipangizo chobowola iyenera kutsegulidwa ndi kutsekedwa mosasunthika popanda kutsekereza kapena kupanikizana.
2.4 kugwirizana ntchito
2.4.1 kukwanirana pakati pa manja obowola ndi choboola kuyenera kukhala kwabwino, ndipo sipadzakhala kupanikizana pakulumikizana.
2.4.2 Chilolezo chokwanira pakati pa manja obowola ndi choboola sichiyenera kupitilira 0.3mm.
2.4.3 pamene chobowola chikugwirizana ndi puncture kondomu, mutu mapeto a puncture kolona ayenera kwathunthu poyera.
2.5 # kulimba komanso kukana gasi
2.5.1 valavu ya jekeseni wa gasi ndi kapu yosindikizira ya chipangizo chobowola idzakhala ndi ntchito yabwino yosindikiza, ndipo sipadzakhala kutayikira pambuyo podutsa mpweya wa 4kPa.
2.5.2 ￠ valavu yotsamwitsa ya chipangizo choboola ikhala ndi ntchito yabwino yotsekereza mpweya.Pambuyo 4kPa mpweya kuthamanga, chiwerengero cha thovu adzakhala zosakwana 20.
2.5.3 chosinthira chizikhala ndi chisindikizo chabwino, ndipo sipadzakhala kutayikira pambuyo podutsa mpweya wa 4kPa.
2.6 ethylene oxide zotsalira
Mankhwalawa amatsukidwa ndi ethylene oxide, ndipo kuchuluka kotsalira kwa ethylene oxide sikuyenera kupitirira 10 µg / g musanachoke kufakitale.
2.7 kubereka
Chogulitsacho chizikhala chosabala.
2.8 pH
Kusiyana kwa mtengo wa pH pakati pa njira yoyesera mankhwala ndi yankho lopanda kanthu sikuyenera kupitirira 1.5.
2.9 zili zonse zazitsulo zolemera
Zomwe zili muzitsulo zolemera muzitsulo zowunikira siziyenera kupitirira 10% μ g/ml.
2.10 zotsalira za evaporation
Zotsalira za evaporation pa 50ml ya njira yoyesera mankhwala siziyenera kupitilira 5mg.
2.11 zinthu zochepetsera (zokhala ndi okosijeni mosavuta)
Kusiyana kwa voliyumu ya potassium permanganate solution [C (KMnO4) = 0.002mol/l] yogwiritsidwa ntchito ndi yankho loyezetsa mankhwala ndi yankho lopanda kanthu lisapitirire 3.0ml.
2.12 UV kuyamwa
Mayamwidwe a yankho la mayeso azinthu mumtundu wautali wa 220nm ~ 340nm sayenera kupitilira 0.4.00000000000000000000000.
