Polyester suture yog ib tug multifilament braided tsis-absorbable, sterile phais suture uas muaj nyob rau hauv ntsuab thiab dawb. Polyester yog ib pawg ntawm cov polymers uas muaj cov ester ua haujlwm hauv lawv cov saw tseem ceeb. Txawm hais tias muaj ntau cov polyesters, lo lus "polyester" raws li cov khoom siv tshwj xeeb feem ntau yog hais txog polyethylene terephthalate (PET). Polyesters suav nrog cov tshuaj uas tshwm sim, xws li hauv cov txiav ntawm cov nroj tsuag cuticles, nrog rau cov khoom siv los ntawm cov txheej txheem loj hlob polymerization xws li polycarbonate thiab polybutyrate. Ntuj polyesters thiab ob peb cov hluavtaws yog biodegradable, tab sis feem ntau hluavtaws polyesters tsis absorbable zoo li polyester suture.

Polyester Surgical Sutures yog qhia rau siv nyob rau hauv dav dav cov ntaub so ntswg approximation thiab / los yog ligation, nrog rau siv nyob rau hauv lub plawv, ophthalmic, thiab neurological txheej txheem. Polyamide suture fibers yog tawv, muaj zog tensile siab, nrog rau elasticity thiab lustre. Lawv yog cov pov thawj wrinkle thiab tiv taus kev puas tsuaj thiab tshuaj lom neeg xws li acids thiab alkalis. Cov iav hloov pauv temp ntawm polyamide yog 47 ° C. Lub suture yog coated nrog silicone kom cov ntaub so ntswg adherence rau lub suture yog tsawg.

Cov yam ntxwv tshwj xeeb ntawm Polyester suture:

Polyester suture yog ib qho tsis-absorbable suture.

Braided rau improvise lub pob caus ruaj ntseg.

Xim ntsuab thiab dawb kom sib txawv ntawm cov khaubncaws sab nraud povtseg ntawm knotting thiab sib txawv b / wa nyob thiab mus tas li suture.

Siab tensile zog

Coated nrog silicone.

Lub suture daim kab xev tsim yog ua los ntawm braided siab zog phais suture khoom. Ib qhov ntev ntawm puag ncig braided suture extends raws tag nrho ntev ntawm daim kab xev suture. Ib feem nruab nrab ntawm daim kab xev suture nta ib lub tiaj tus braid ntxiv rau puag ncig braided suture. Lub suture yog muab tso rau hauv nruab nrab rau hauv lub tiaj tus braid, muab lub nraub qaum rau kev tsim. Cov kev hloov pauv ntawm qhov kawg ntawm lub tiaj tus braid yog tapered kom tso cai rau daim kab xev suture kom yooj yim los ntawm kev qhib thaum lub sij hawm phais. Daim kab xev suture yog braided kev tsim kho ntawm ultrahigh molecular hnyav polyethylene fibers sib xyaw nrog fibers ntawm ib los yog ntau tshaj cov saw hlau hluavtaws polymers, nyiam dua polyester. Daim kab xev suture yog qhia rau kev thov siab kho orthopedic xws li arthroscopic reconstruction rau acromioclavicular sib cais, piv txwv li. Qhov dav hneev taw ntawm daim kab xev suture yog tsim nyog rau kev kho nyob rau hauv cov ntaub so ntswg degenerative cuff qhov twg cov ntaub so ntswg rub-los ntawm yuav muaj kev txhawj xeeb.

Polyester daim kab xev yog non-absorbable, daim kab xev retraction yog siv dav hauv retraction thaum cov txheej txheem phais. Ua los ntawm poly (ethylene, terephthalate), daim kab xev yog non-absorbable, braided rau kev saib xyuas cov khoom thiab muaj undyed (dawb).
