UHWMPE vet sutures kit
Txawm hais tias cov qauv molecular ntawm UHMWPE yog tib yam li cov polyethylene zoo tib yam, nws muaj ntau yam khoom zoo uas cov polyethylene zoo tib yam tsis muaj vim nws qhov hnyav heev ntawm cov txheeb ze molecular. Zoo li: Superior hnav tsis kam, Tsis tshua muaj kev sib txhuam coefficient, Tsis muaj tshuaj lom thiab tsis muaj ntxhiab, Nto tsis-adhesion, tsis muaj scaling, Tsawg kub tsis kam, tshuaj tsis kam.
Ultrahigh molecular hnyav polyethylene muaj qhov hnav tsis kam ua haujlwm txog 27 npaug siab dua cov hlau tsis muaj steel. Txawm tias nyob rau hauv ib puag ncig hnyav, UHMWPE cov khoom tseem tuaj yeem txav tau yooj yim, kom ntseeg tau tias cov khoom ua haujlwm cuam tshuam yuav tsis hnav thiab rub. Vim nws qhov sib txhuam me me thiab tsis muaj polarity, UHMWPE muaj cov khoom tsis sib xws. Ultrahigh molecular hnyav polyethylene raj tuaj yeem khaws cia ntawm -269 ℃ thiab 80 ℃ rau lub sijhawm ntev. Vim tias cov molecules unsaturated nyob rau hauv cov saw molecular muaj tsawg thiab qhov ruaj khov yog siab, qhov kev laus yog qhov tshwj xeeb qeeb. Ultrahigh molecular hnyav polyethylene (UHMWPE) muaj cov tshuaj tiv thaiv zoo heev, thiab ntau cov xov xwm corrosive thiab cov kuab tshuaj organic kuj tsis muaj txiaj ntsig rau nws hauv qee qhov kub thiab txias.
Nrhiav lub zog tensile siab dua yog ib txwm lub hom phiaj ntawm kev phais sutures. Qhov tshwj xeeb parameter ntawm saum toj no ua UHMWPE ua cov khoom zoo tshaj plaws ntawm orthopedic sutures. Lub pob caus rub lub zog tensile txawm siab dua polyester uas tsim cov khoom sib txawv sutures rau cov leeg kho thiab hloov, uas suav nrog Luj tshib, Tes Dab teg thiab lwm yam, tshwj xeeb tshaj yog rau cov tsiaj me. Nws tau braided hauv Dawb-Blue, Dawb-Green thiab lwm yam sib txawv ua ke ntawm cov xim kom muaj qhov pom kev yooj yim thaum lub sijhawm phais nyuaj. Ua kom cov xov mos mos thiab yooj yim los tuav, qee lub tuam txhab braided ua ke nrog cov hlua ntev polyester fiber li lub tsho uas muab kev ua haujlwm zoo dua. Txhawm rau kom tsis muaj zog nrog kev raug mob tsawg, daim kab xev tau qhia ua ib feem ntawm cov khoom siv. Cov khoom siv no xav tau kev cob qhia tshwj xeeb ntawm tus kws kho tsiaj kws kho mob kom paub meej qhov txiaj ntsig zoo. Los ntawm kev qhia txog cov no, cov tsiaj lub neej tau kho zoo dua.
