Yuav ua li cas xaiv txoj cai roj hmab foob rau hluav taws xob scalpel
Xav txog biocompatibility
Qhov tseem ceeb
Txij li thaum hluav taws xob scalpels nyob rau hauv kev sib cuag ncaj qha nrog tib neeg cov ntaub so ntswg thiab lub cev kua thaum lub sij hawm kev phais, roj hmab seals yuav tsum tau biocompatible. Qhov no yog qhov tseem ceeb hauv kev ua kom cov neeg mob muaj kev nyab xeeb, vim tias cov ntaub ntawv tsis sib haum tuaj yeem ua rau muaj kev tiv thaiv kab mob, kev tsis haum tshuaj, lossis lwm yam tshwm sim tsis zoo ntawm lub cev.
Txoj kev ntsuam xyuas
Xa mus rau cov qauv kev kho mob thiab cov ntawv pov thawj cuam tshuam, xws li ISO 10993 series ntawm cov qauv, uas muab cov ncauj lus ntxaws ntxaws rau kev soj ntsuam biocompatibility ntawm cov cuab yeej kho mob.
Txheeb xyuas cov ntawv qhia txog biocompatibility uas muab los ntawm tus neeg muab khoom foob kom paub meej tias lub foob tau dhau los ua cov kev ntsuas cuam tshuam xws li kev sim cytotoxicity, kuaj sensitization, kuaj stimulation, thiab lwm yam, thiab cov txiaj ntsig tau raws li qhov yuav tsum tau ua ntawm kev lag luam kho mob.
Tsom ntsoov rau corrosion kuj
Kev phais ib puag ncig yam
Hluav taws xob scalpels raug rau ntau yam tshuaj ua ntej thiab tom qab siv, xws li tshuaj tua kab mob (glutaraldehyde, hydrogen peroxide, thiab lwm yam), saline, thiab lwm yam. Roj hmab seals yuav tsum muaj peev xwm tiv taus cov tshuaj no kom tswj tau lawv cov khoom sealing.
Kev xaiv khoom
Fluoroelastomer (FKM) yog cov khoom siv roj hmab uas muaj kev tiv thaiv zoo heev thiab kev ua haujlwm zoo rau ntau cov tshuaj, ua rau nws xaiv zoo rau hluav taws xob scalpel seals.
Silicone roj hmab kuj muaj qee qhov kev tiv thaiv corrosion, tshwj xeeb tshaj yog ua haujlwm zoo rau cov tshuaj me me xws li cov ntsev ib txwm muaj, thiab muaj qhov yooj yim thiab biocompatibility, uas tuaj yeem siv rau qee kis.
Flexibility thiab abrasion kuj tseem ceeb
Flexibility xav tau
Thaum lub sijhawm ua haujlwm ntawm hluav taws xob scalpels, cov ntsaws ruaj ruaj yuav tsum tau hloov mus rau qhov sib txawv ntawm cov kev hloov pauv, tshwj xeeb tshaj yog nyob rau ntawm qhov sib txuas ntawm lub taub hau thiab lub shank. Roj Hmab cov ntsaws ruaj ruaj nrog zoo yooj tuaj yeem tswj tau lawv cov kev sib khi txawm tias lawv raug crushed, khoov, lossis lwm yam deformed.
Abrasion kuj xav txog
Vim yog siv scalpels ntau zaus thaum lub sij hawm phais, cov ntsaws ruaj ruaj tas li raug kev sib txhuam. Xaiv cov khoom siv roj hmab uas muaj zog abrasion kuj tuaj yeem txuas lub neej ntawm lub foob. Piv txwv li, cov roj hmab nitrile (NBR) muaj qhov zoo abrasion tsis kam thiab kuj muaj qee qhov yooj, uas yog ib qho ntawm cov ntaub ntawv uas tuaj yeem txiav txim siab.
Raws li cov kev cai sealing kev ua tau zoo
sealing siab
Cov txheej txheem hluav taws xob sib txawv tuaj yeem muaj qhov sib txawv rau kev sib khi. Nyob rau hauv lub foob ntawm lub shank vaj tse, lub sealing siab dua yuav tsum tau los tiv thaiv cov ingress ntawm sab nraud cov kua thiab paug. Nyob ntawm qhov tshwj xeeb scalpel tsim thiab siv ib puag ncig, nws yog ib qho tsim nyog los xaiv cov roj hmab foob uas tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm sealing siab.
sealing raug
Rau lub foob ntawm kev sib txuas ntawm lub taub hau cutter thiab lub cuab yeej tuav, sealing raug yuav tsum tau ua kom muaj kev ruaj ntseg ntawm lub taub hau cutter thiab tiv thaiv cov kua infiltration. Nws tuaj yeem ntsuas seb lub foob puas ua tau raws li qhov yuav tsum tau ua ntawm kev sib khi qhov tseeb los ntawm kev ntsuas nws qhov tseeb qhov tseeb, qhov roughness ntawm qhov chaw, thiab lwm yam.
Xav txog qhov kub thiab txias
Kub hloov pauv hauv qhov chaw ua haujlwm
Qhov kub hauv chav ua haujlwm tuaj yeem hloov pauv mus rau qee qhov, thiab hluav taws xob scalpel ua kom sov ntawm nws tus kheej thaum ua haujlwm. Roj hmab foob yuav tsum tswj lawv lub cev, xws li elasticity, hardness, thiab lwm yam., nyob rau hauv ib tug tej yam kub thiab txias.
Cov yam ntxwv kub ntawm cov khoom
Silicone roj hmab muaj qhov sib txawv ntawm qhov kub thiab txias, uas tuaj yeem tswj tau qhov yooj yim thiab sealing kev ua tau zoo nyob rau hauv ntau qhov kub thiab txias, thiab haum rau hluav taws xob scalpel sealing ib puag ncig nrog kev hloov pauv kub.
