Tsim Cov Ntsiab Cai Ntawm Slotted Rigid Hypotube

Slotted Rigid Hypotube sawv cev rau ib pawg tshwj xeeb ntawm laser-machined metallic tubing tsim tshwj xeeb rau cov khoom siv kho mob siab uas xav tau cov kev taw qhia ncaj nraim uas tsis muaj kev cuam tshuam, qhov siab tshaj plaws kem lub zog, thiab meej 1: 1 torque kis tau tus mob. Tsis zoo li slotted semi-rigid hypotubes optimized rau elastic dabtsi yog khoov thiab lub caij nplooj ntoos hlav-rov qab, lub Slotted Rigid Hypotube ua qhov tseem ceeb ntawm cov txheej txheem nruj thaum qhia txog kev tsim kho kev ntxhov siab los ntawm staggered, cuam tshuam laser-txiav cov qauv. Cov qauv tsim no daws qhov tsis ua haujlwm ntev ntev ntawm cov khoom siv tsis sib xws: kev puas tsuaj loj thiab buckling nyob rau hauv kev ntxhov siab rau sab nraud lossis tsis xav txog ntau dhau, uas tuaj yeem cuam tshuam cov khoom siv phais mob ib nrab ntawm cov txheej txheem.

Lub hauv paus engineering logic yog nyob rau hauv qhov sib npaug ntawm cov txuas hlau tsis sib haum thiab cov qhov sib txawv ntawm kev ntxhov siab. Txhua qhov staggered qhov yog xam qhov tseeb hauv kerf dav, circumferential offset thiab axial suab. Feem ntau cov hlau tsis muaj hlau tseem nyob ruaj khov ntawm lub raj phab ntsa, khaws cia lub ntiaj teb torsional rigidity thiab axial compressive peev xwm. Qhov sib quas ntus qhov chaw tsis tsim qhov chaw khoov tau yooj yim; Tsis tas li ntawd, lawv ua raws li lub hauv paus kev ntxhov siab dissipators uas kis tau cov ntsiab lus siab tshaj plaws hla cov phab ntsa uas nyob ib sab. Thaum muaj kev cuam tshuam rau sab nraud lossis compressive overload tshwm sim, kev ntxhov siab yog rov faib dua dua li qhov sib npaug ntawm ib qho taw tes, tiv thaiv kev sib tsoo los yog lub raj tawg yam tsis muaj kev qhia tsis xav tau deflection.

Rau cov kws tsim khoom siv kho mob, Slotted Rigid Hypotube muab peb lub hauv paus ntawm cov khoom siv hluav taws xob: superior axial pushability, xoom-lag rotational torque hloov, thiab tiv thaiv kev tiv thaiv. Axial pushability txhais tau tias kev ntseeg siab npaum li cas ntawm cov ncej tuaj yeem ua tiav los ntawm cov ntaub so ntswg, thaj chaw caws pliav lossis nruj nruj yam tsis muaj qhov deflection lossis rov qab buckling . 1}: 1 torque fidelity ua kom muaj kev sib hloov ntawm kev sib tw siv ntawm qhov sib thooj kov reproduces zoo ib yam ntawm lub distal ua hauj lwm tip, ionalisers eliminating. Lub zog-txhim kho ua haujlwm ua haujlwm ua haujlwm tsis raug cai rau kev phais mob tiag tiag hauv lub ntiaj teb uas tsis tuaj yeem zam lub zog tawm.

Kev tsim khoom pib los ntawm precision puag hypotubes thiab siv cov qib siab fiber ntau laser micro-txiav los tsim staggered interrupted qhov geometry. Thaum tshav kub kub-cuam tshuam cov cheeb tsam raug tswj nruj kom tsis txhob muaj cov khoom embrittlement thiab micro-crack pib ntawm cov npoo, qhov teeb meem tseem ceeb rau laser-processed kho mob hlau Cheebtsam. Tom qab kev ua tiav suav nrog electropolishing, passivation thiab tag nrho internal-sternal deburring. Burr-free deg tshem tawm cov kev ntxhov siab-txhawb nqa thiab ua kom muaj kev sib koom ua ke zoo nrog cov tsho polymer thiab sab hauv stylets, txo kev sib txhuam rau kev txav mus los ntawm sab hauv.

Dimensional tolerances yog nruj me ntsis tswj nrog sab kab uas hla kam rau siab mus txog ± 0.01 hli. Kev cai sab nraud txoj kab uas hla npog micro Ø1.0 hli txog Ø15.0 hli thiab siab dua. Phab ntsa tuab yog tsim los ua kom sib npaug hauv qhov chaw lumen tiv thaiv radial crush tsis kam, tso cai rau cov neeg tsim khoom khaws cia lumen ntim rau cov lus qhia, cov kav dej los yog cov khoom ua haujlwm sab hauv thaum tuav cov khoom siv zog siab. Txhua yam kev tsim khoom ua raws li ISO 13485 cov txheej txheem zoo. Cov shafts tiav tau txais axial compression thiab torsional validation xeem kom paub meej tias lawv yuav tsis tawm los raws li kev phais-txog loads. Raws li cov pob txha pob txha rau txhav endoscopes, hnyav-lub luag hauj lwm xa catheters, trocar cannulas thiab orthopedic cov lus qhia, lub Slotted Rigid Hypotube nyob rau hauv ib qho tseem ceeb engineering niche ntawm tag nrho cov rigid tubes thiab saj zawg zog slotted hypotube variants rau niaj hnub minimally-invasive phais tshuab.
