mankhwala

Polyester suture ndi multifilament yolukidwa osatengeka, wosabala opaleshoni suture yomwe imapezeka yobiriwira ndi yoyera. Polyester ndi gulu la ma polima omwe ali ndi gulu logwira ntchito la ester mu unyolo wawo waukulu. Ngakhale pali ma polyester ambiri, mawu oti "polyester" ngati zinthu zenizeni nthawi zambiri amatanthauza polyethylene terephthalate (PET). Ma polyesters amaphatikizapo mankhwala opangidwa mwachilengedwe, monga mu cuticles zamitengo, komanso zopangira polima polima monga polycarbonate ndi polybutyrate. Ma polyester achilengedwe ndi ena ochepa opangidwa amatha kuwonongeka, koma ma polyester ambiri opangidwa samatha kuyamwa ngati suture ya poliyesitala.

Polyester Surgical Sutures amasonyezedwa kuti agwiritsidwe ntchito pafupifupi pafupifupi minofu yofewa komanso / kapena ligation, kuphatikizapo kugwiritsidwa ntchito pamtima, ophthalmic, ndi minyewa. Ulusi wa polyamide suture ndi wolimba, wokhala ndi mphamvu zolimba kwambiri, komanso elasticity ndi kunyezimira. Sachita makwinya ndipo sagonjetsedwa kwambiri ndi abrasion ndi mankhwala monga ma acid ndi alkalis. Kutentha kwa galasi la polyamide ndi 47 °C. Chovalacho chimakutidwa ndi silicone kotero kuti kutsatiridwa kwa minofu ku suture kumakhala kochepa.

Makhalidwe Osiyana a Polyester suture:

Polyester suture ndi suture yosasunthika.

Amalukidwa kuti apititse patsogolo chitetezo cha mfundo.

Mtundu wobiriwira ndi woyera kuti usiyanitse pakati pa zigawo za knotting ndikusiyanitsa b / wa kukhala ndi suture yokhazikika.

Mphamvu yapamwamba kwambiri

Zopangidwa ndi silicone.

Tanyani

Chopangidwa ndi tepi ya suture chimapangidwa ndi zida zolukira mwamphamvu kwambiri. Kutalika kwa suture yoluka yozungulira kumafikira kutalika konse kwa tepi ya suture. Chigawo chapakati cha tepi ya suture chimakhala ndi nsalu yopyapyala yowonjezeredwa ku suture yoluka yozungulira. Chovalacho chimaphatikizidwa pakati pazitsulo zokhazikika, zomwe zimapereka msana pakupanga. Magawo osinthira kumapeto kulikonse kwa cholumikizira chathyathyathya amamangika kuti tepi ya suture idutse mosavuta pamipata panthawi ya opaleshoni. Tepi ya suture ndi yomangika yokhala ndi ulusi wa polyethylene wolemera kwambiri wa molekyulu wosakanikirana ndi ulusi wa ma polima opangidwa ndi unyolo umodzi kapena zingapo, makamaka poliyesitala. Tepi ya suture imasonyezedwa pofuna kukonzanso mafupa a mafupa monga kumangidwanso kwa arthroscopic kwa kupatukana kwa mgwirizano wa acromioclavicular, mwachitsanzo. Mzere wotakata wa tepi ya suture ndi yoyenera kukonzanso minofu yowonongeka kumene minofu ingakhale yodetsa nkhawa.

Tepi ya polyester ndiyosasunthika, tepi yochotsa ndi yogwiritsidwa ntchito nthawi zonse pakubweza panthawi ya opaleshoni. Wopangidwa ndi poly (ethylene, terephthalate), tepiyo ndi yosasunthika, yolukidwa kuti igwire bwino ntchito ndipo imapezeka yosasinthidwa utoto (yoyera).
