Polyester suture ndeye multifilament yakarukwa isingabatike, isina kuvhiyiwa suture inowanikwa mune yegirinhi uye chena.Polyester iboka remapolymer ane iyo ester inoshanda boka mumaketani avo makuru.Kunyangwe paine mapolyester akawanda, izwi rekuti "polyester" sechinhu chakasarudzika chinowanzo reva polyethylene terephthalate (PET).Polyesters inosanganisira makemikari anongoitika, senge mukucheka kwezvirimwa cuticles, pamwe nekugadzira kuburikidza nenhanho-yekukura polymerization senge polycarbonate uye polybutyrate.Mapolyester echisikigo uye mashoma ekugadzira anogona kugadzirwa, asi akawanda ekugadzira mapolyester haabatike senge polyester suture.

Polyester Surgical Sutures inoratidzwa kuti ishandiswe mune zvakajairika zvinyoro zvinyoro fungidziro uye / kana ligation, kusanganisira kushandiswa mumoyo, ophthalmic, uye neurological maitiro.Polyamide suture fibers yakasimba, iine simba rakanyanya kusimba, pamwe nekusimba uye kupenya.Iwo anodzivirira kuunyana uye anopokana zvakanyanya neabrasion uye makemikari akadai seasidhi uye alkalis.Tembiricha yegirazi yepolyamide i47 °C.Iyo suture yakaputirwa nesilicone kuitira kuti kunamatira kwenyama kune suture kushoma.

Hunhu hwakasiyana hwePolyester suture:

Polyester suture is absorbable suture.

Yakarukwa kuti ivandudze kuchengetedzwa kwepfundo.

Ruvara rwegirini uye ruchena kusiyanisa pakati pezvikamu zveknotting uye kusiyanisa b/wa kugara uye suture yekusingaperi.

High tensile simba

Yakaputirwa nesilicone.

Iyo suture tepi yekuvaka inogadzirwa neyakarukwa yakakwira simba rekuvhiya suture zvinhu.Hurefu hwedenderedzwa rakarukwa suture inotambanudzira kureba kwese tepi yesuture.Chikamu chepakati che tepi yesuture inoratidzira flat braid yakawedzerwa kune yakatenderedzwa yakarukwa suture.Iyo suture inosanganiswa nechepakati mukati me flat braid, ichipa musana wekuvaka.Zvikamu zvekuchinja kune chero kumagumo kweflat braid zvinotemerwa kutendera tepi yesuture kuti ipfuure nyore nepamazaru panguva yekuvhiya.Iyo suture tepi chivakwa chakarukwa cheiyo ultrahigh molecular weight polyethylene fiber yakasanganiswa nefiber imwe kana akawanda akareba cheni mapolymers, zviri nani polyester.Iyo suture tepi inoratidzwa kune yakanyanya kudiwa kugadziriswa kwemapfupa senge arthroscopic reconstruction yeacromioclavicular joint separation, semuenzaniso.Iyo yakafara tsoka yeiyo suture tepi yakakodzera kugadzirisa mune inoderera cuff tishu uko tishu kudhonza-kuburikidza kungave kunetseka.

Polyester tepi haibatike, iyo yekudzosera tepi ndeyekushandiswa kwese mukudzoreredza panguva yekuvhiya.Inoumbwa nepoly (ethylene, terephthalate), tepi haibatike, yakarukwa kuti inyatso kubata zvivakwa uye inowanikwa isina kudhayiwa (chena).
