Endoscopic biopsy koobtsis ua haujlwm ntawm nws tus kheej; lawv yuav tsum tau xa mus rau hauv lub cev los ntawm endoscope qhov ntev, nqaim "ua haujlwm channel." Cov channel no feem ntau tsuas yog 2.0 hli lossis 2.8 hli tuab thiab tau sau nrog S- zoo li tus khoov khoov thoob plaws nws qhov ntev. Yog hais tias lub koob raj yog nruj dhau los yog tsis txaus, nws yuav kink los yog jam ntawm qhov khoov, uas yuav ua rau lub endoscope kim kim thiab yuam kev phais kom nres.
Yog li ntawd, thaum tsim cov koob tshuaj endoscopic biopsy, cov neeg tsim khoom yuav tsum ua kom nruj"bending passability xeem"thiab"Qhov kev xeem torque kis tau tus mob." High-cov koob zoo yuav tsum muaj qhov ua tau zoo tshaj plaws thiab kink tsis kam, ua kom cov zawv zawg du nyob rau hauv ib qho endoscope channel khoov ntawm 180 degree, nrog lub zog sib kis ntau dua lossis sib npaug li 70%. Qhov no txhais tau hais tias thaum tus kws kho mob tig tus kov sab nraum lub cev, lub koob taub rotates synchronously, precisely kho lub qhov rais kev taw qhia kom fim qhov txhab. Yog tias qhov kis tau tus mob tsawg dhau, tus kws kho mob tig tus kov tab sis lub koob lub taub hau tseem nyob ruaj khov, tiv thaiv qhov chaw raug thiab ua rau muaj kev raug mob vascular raug mob.
Tsis tas li ntawd, ergonomic tsim ntawm tus kov yog feem ntau overlooked. Lub thawb tsis kam ntawm tus ntiv tes xoo slider yuav tsum nyob nruab nrab ntawm 0.8-1.5 N; Lub teeb dhau dhau ua rau kev ua haujlwm tsis sib xws, thaum hnyav dhau ua rau tus ntiv tes qaug zog rau tus kws kho mob. Cov khoom siv tes yuav tsum yog kev kho mob -qib PP lossis ABS nrog tiv thaiv -slip texturing. Cov neeg tsim khoom yuav tsum ua kom muaj "Compatibility Matrix Table," teev cov kev hloov pauv rau ntau yam Olympus, Pentax, Fujifilm, thiab lwm yam endoscope qauv, qhia meej txog cov ntaub ntawv passability nyob rau hauv siab tshaj plaws bending kaum. Cov neeg yuav khoom yuav tsum tau txais lub rooj no ua ntej muab kev txiav txim kom tsis txhob txaj muag thiab kev pheej hmoo kho mob ntawm "lub koob mus rau hauv tab sis yuav tsis tig" thaum lub sijhawm phais tiag tiag.
