I-polyethylene enesisindo esiphezulu-high-molecular
I-Ultra-high-molecular-weight polyethylene iyisethi engaphansi ye-thermoplastic polyethylene. Eyaziwa nangokuthi i-high-modulus polyethylene, inamaketanga amade kakhulu, enesisindo samangqamuzana ngokuvamile phakathi kwe-3.5 ne-7.5 million amu. Iketango elide lisebenza ukudlulisa umthwalo ngokuphumelelayo kumgogodla we-polymer ngokuqinisa ukusebenzisana kwama-intermolecular. Lokhu kubangela into eqinile kakhulu, enamandla amakhulu okushayisana kwanoma iyiphi i-thermoplastic eyenziwe manje.
Izimpawu ze-WEGO UHWM
I-UHMW (i-ultra-high-molecular-weight polyethylene) inikeza inhlanganisela yezakhiwo ezihlukile. Le nto ye-thermoplastic iqinile futhi inamandla omthelela aphezulu. Ayizwani nokugqwala futhi ayibonisi nhlobo ukumuncwa kwamanzi. Iphinde imelane nokugqokwa, ayinamathiseli futhi izigcobisa yona.
I-UHMW iyisinqumo esihle kakhulu sezinhlelo zokusebenza eziningi zezimboni. Inciphisa umsindo nokudlidliza, ayimelani namakhemikhali futhi ayinabo ubuthi futhi inikeza izakhiwo ezinhle kakhulu zemishini ngisho nasezimeni ze-cryogenic. Izici zifaka:
Ayinabuthi.
I-coefficient ephansi yokungqubuzana.
Ukugqwala, imihuzuko, ukuguga kanye nomthelela.
Ukumuncwa kwamanzi okuphansi kakhulu.
I-FDA ne-USDA igunyaziwe.
Izicelo ze-UHMW Thermoplastic.
Izingubo zokugqoka.
Izingxenye zokucubungula ukudla.
Amathangi amakhemikhali.
Iziqondiso zokuthutha.
Gqoka amaphedi.
UHMWPE TAPE SUTURES ( I-TAPE)
I-UHMWPE Sutures amaSutures okwenziwa okuyinyumba angenakumuncwa akhiwe nge-ultra-high molecular weight polyethylene (UHMWPE). I-tape inikeza amandla amahle kakhulu, ukumelana nokuhuzuka okungcono kune-polyester, ukuphatha okungcono nokuvikeleka kwefindo/amandla.Ama-sutures we-tape ahlinzekwa ekucushweni kwetheyiphu.
Izinzuzo:
● Ukumelana ne-abrasion kuphakeme kune-polyester.
● Isakhiwo esiyisiyingi ukuya kusicaba; inikeza inguquko ebushelelezi.
● Ngendawo yayo eyisicaba yesakhiwo se-tape, isiza ukusekela nokusabalalisa imithwalo.
● Ihlinzeka ngokulungiswa kwendawo enkulu ngesakhiwo sayo esibanzi, esiyisicaba, esilukiwe uma kuqhathaniswa nomthungo ovamile.
● Imicu ye-warp enombala ithuthukisa ukubonakala.
● Itholakala ngemibala eminingi: emnyama okuqinile, eluhlaza okwesibhakabhaka, emhlophe, emhlophe & eluhlaza okwesibhakabhaka, eluhlaza okwesibhakabhaka nokumnyama.
UHMWPE SUTURESi-synthetic engamunceki, i-ultra-high molecular weight polyethylene (UHMWPE) suture enikezwa ekucushweni komcu.
Izinzuzo:
● Ukumelana ne-abrasion kuphakeme kune-polyester.
● Isakhiwo esiyindilinga-kuya-esicaba sinikeza iphrofayela ephansi kakhulu namandla amakhulu.
● Itholakala ngemibala eminingi: emnyama eqinile, eluhlaza okwesibhakabhaka, emhlophe, emhlophe & eluhlaza okwesibhakabhaka, emhlophe & emnyama, emhlophe & eluhlaza okwesibhakabhaka & emnyama, emhlophe & eluhlaza.
● Ubuchwepheshe be-Inter-locking core ubuchwepheshe obuhlinzeka ngomgogodla oqinile nakho konke ukulungiselelwa kwefayibha enkabeni yomthungo. Mayelana nalobu buchwepheshe, ifindo lisebenza njengomgogodla ngokuboshwa kangcono nokuthwala umthwalo.
● Inikeza amandla amahle kakhulu wokuguquguquka.
● Isakhiwo se-E-braid sinikeza ukuphatha okungcono namandla efindo.
● Inikeza ukubonakala okuhle ngamaphethini e-triaxial nemibala egqamile.
i-suture isetshenziselwa ukuvala kanye/noma ukuxhunyaniswa kwezicubu ezithambile, okuhlanganisa ukusetshenziswa kwezicubu ze-allograft zokuhlinzwa kwenhliziyo nemithambo yegazi kanye nezinqubo zamathambo.
Ukusabela kokuvuvukala kwe-suture esicutshini kuncane. Kancane kancane i-encapsulation yenziwa nge-fibrous connective tissue.
i-suture ifakwe inzalo nge-Ethylene oxide.
i-suture itholakala ngezinaliti noma ngaphandle kwazo ngobude obunqunyiwe ngaphambili.
