Laparoscopic cannulas yog cov cuab yeej tseem ceeb rau kev phais mob plab me me. Lawv yog cov khoom tseem ceeb rau kev tsim pneumoperitoneum, ntxig cov khoom siv endoscopic thiab ua cov txheej txheem phais tag nrho. Cov khoom siv raw zoo ncaj qha cuam tshuam rau kev nyab xeeb ntawm kev phais, kev pabcuam lub neej, sealing stability thiab tshwm sim ntawm cov teeb meem tom qab phais. Cov tuam txhab lag luam laparoscopic loj thoob ntiaj teb suav nrog kev tshawb fawb cov ntaub ntawv kho mob raws li kev sib tw tseem ceeb. Centering ntawm peb cov ntaub ntawv tseem ceeb suav nrog cov hlau tsis muaj steel, titanium alloy thiab kev kho mob polymers, lawv txuas ntxiv txhim kho cov qauv tsim khoom, tsim cov tswv yim thiab ua kom tsis muaj menyuam, tsim cov khoom lag luam sib txawv, thiab ua kom muaj kev sib txawv ntawm kev phais thiab kev tswj hwm tus nqi ntawm cov tsev kho mob txhua qib.

Kev kho mob stainless hlau boasts qhov ntev tshaj plaws kev kho mob daim ntawv thov keeb kwm thiab widest muaj koob meej raws li lub hauv paus khoom rau laparoscopic cannulas. High- qib kho mob 316L stainless hlau yog siv rau feem ntau reusable cannulas resistant rau siab -kub sterilization. Tsim cov tuam txhab thoob ntiaj teb xws li Johnson & Johnson thiab Stryker xaiv cov ntaub ntawv nruj raws li ISO 13485 kev tswj hwm zoo thiab ASTM cov qauv rau cov khoom siv kho mob hlau. Cov khoom nta zoo heev corrosion kuj, structural rigidity thiab superior biocompatibility, ua rau tsis muaj kev tsis haum, tsis kam los yog teeb meem tshuaj nag lossis daus thaum lub sij hawm ntev - kev sib cuag nrog cov ntaub so ntswg plab. Ua tiav los ntawm precision CNC tig, sab hauv phab ntsa polishing thiab chamfering passivation, stainless hlau cannulas muaj ultra- du sab hauv qhov chaw uas ua rau cov cuab yeej siv tau zoo yam tsis muaj jamming lossis plab phab ntsa khawb. Muaj peev xwm ua kom muaj zog ntau dua -siab ua kom tsis muaj menyuam, cov cannulas tiv thaiv kev deformation, puas thiab huab cua to, thiab tswj kev ua haujlwm ruaj khov hauv kev siv ntau zaus. Lawv sawv ntsug raws li cov khoom siv nyiam rau kev ua haujlwm laparoscopic niaj hnub hauv kev phais dav dav thiab phais hepatobiliary ntawm sab saum toj- cov tsev kho mob qib.

Titanium alloy yog cov khoom siv kho mob zoo tshaj plaws, feem ntau siv rau cannulas rau kev phais laparoscopic ntev thiab sophisticated. Compared with stainless steel, it features lower density, lighter weight, higher fatigue resistance and better biological inertness with minimal irritation to human tissues. Cov tuam txhab lag luam hauv tsev suav nrog Kangji Medical thiab WEGO Orthopedics khaws cov titanium alloy forging thiab precision sib tsoo technologies, thiab optimize raj phab ntsa thickness thiab puncture tip qauv. Cov qauv tsim txo cov cuab yeej hnyav thaum tuav cov txheej txheem lub zog, ua kom cov kws phais neeg mob lub cev qaug zog thaum ua haujlwm ntev. Titanium alloy cannulas xa zoo kawg li khoov tsis kam, hnav tsis kam thiab electrochemical corrosion kuj. Lawv muaj feem xyuam rau cov txheej txheem nyuaj xws li kev phais gynecological sib sib zog nqus, kho cov kab mob hepatobiliary thiab puncture ntawm cov phab ntsa tuab hauv plab ntawm cov neeg mob rog, nrog rau ntev tshaj - lub sij hawm kev nyab xeeb thiab kav ntev dua li cov khoom siv stainless hlau.

Kev kho mob tshwj xeeb polymers ua raws li cov khoom siv tseem ceeb ntawm cov khoom siv pov tseg laparoscopic cannulas, loj- tsim los ntawm cov neeg muag khoom hauv tsev xws li Mindray Medical thiab Bluesail Medical. Cov ntaub ntawv kho mob polycarbonate thiab hloov kho cov ntaub ntawv polymer yog molded nyob rau hauv sterile tej yam kev mob rau kev siv ib zaug, tshem tawm cov txheej txheem tom qab phais thiab hauv paus tsis txhob hla - kis kab mob. Cov hlab ntsha muaj qhov hloov tau yooj yim kom txo tau qhov raug mob. Integrally txhaj tshuaj-cov qauv valve ua tau zoo heev pneumoperitoneum nruj, nrog cov nqi qis dua thiab kev sib raug zoo. Lub siab pob tshab ua rau cov kws phais neeg saib xyuas ncaj qha rau ntawm lub plab phab ntsa cov ntaub so ntswg thiab txo qhov kev raug mob ntawm cov hlab ntsha thiab cov kab mob visceral.

Kev lag luam cov ntaub ntawv kev loj hlob qauv leans mus rau integrated composite lug. Cov tuam txhab ua lag luam tsim cov cannulas ua ke nrog cov lus qhia hlau thiab cov raj polymer, ntsuas qhov sib tsoo lub zog, lub teeb yuag tsim, airtightness thiab kev nyab xeeb. Daim ntawv thov cov ntaub ntawv ua kom zoo, txhim kho qib kev nyab xeeb kev kho mob thiab ntau yam - qhov xwm txheej hloov kho kom zoo ua rau cov khoom lag luam kho dua tshiab, txhawb nqa tus qauv thiab siab - kev txhim kho zoo ntawm kev phais me me.
