Absorbable suture
Absorbable sutures inokamurwazve kuita: ura, makemikari synthesized (PGA), uye akachena echisikigo collagen sutures zvichienderana nechinhu uye dhigirii rekunyura.
1. Ura hwemakwai: Yakagadzirwa kubva kumhuka ine hutano hwai uye ura hwembudzi uye ine collagen zvikamu. Nokudaro, hazvidiwi kubvisa thread mushure me suturing. Medical gut line: yakajairika gut mutsara uye chrome gut mutsara, ese ari maviri anogona kubatwa. Urefu hwenguva inodiwa pakunyura hunoenderana nekukora kweura uye mamiriro enyama. Inowanzo kunyudzwa kwemazuva matanhatu kusvika makumi maviri, asi mutsauko wega wega unokanganisa maitiro ekunyudza kana kunyange kutora. Parizvino, ura unogadzirwa nekuraswa aseptic packaging, iri nyore kushandisa.
(1) Ordinary gut: suture inogoneka nyore nyore yakagadzirwa kubva kune submucosal tishu yemudumbu kana bovine intestine. Kutora kunokurumidza, asi mutsara unopindura zvishoma kune ura. Inowanzo shandiswa kurapa nekukurumidza tsinga dzeropa kana subcutaneous tishu kune ligature tsinga dzeropa uye suture utachiona maronda. Inowanzoshandiswa mucosal layers sechibereko uye dundira.
(2) Chrome gut: Ura uhu hunogadzirwa nechromic acid kurapwa, iyo inogona kunonoka kunyudzwa kwetishu, uye inokonzeresa kuzvimba kushoma pane zvakajairika ura. Inowanzo shandiswa pakuvhiya gynecological uye urinary, is suture inowanzoshandiswa mukuvhiya itsvo uye ureter, nekuti silika inosimudzira kuumbwa kwematombo. Nyora mumvura ine munyu panguva yekushandiswa, ruramisa mushure mekunyorova, kuitira kuti basa rive nyore.
2, kemikari synthesis mutsara (PGA, PGLA, PLA): polymer mutsara zvinhu zvakagadzirwa neazvino makemikari tekinoroji, kuburikidza nemaitiro ekudhirowa, kupfekedza uye mamwe maitiro, anowanzo kunyudzwa mukati memazuva makumi matanhatu-90, kunyura kugadzikana. Kana chiri chikonzero chekugadzirwa kwekugadzira, kune zvimwe zvisingasviki makemikari zvikamu, kutora hakuna kukwana.
3, yakachena yakasikwa collagen suture: yakatorwa kubva kune yakakosha mhuka raccoon tendon, yakakwira yakasikwa collagen yemukati, maitiro ekugadzira pasina kutora chikamu chemakemikari zvikamu, ane hunhu hwecollagen; yezvino yechokwadi yechina Generation ye sutures. Iyo ine kunyura kwakazara, yakanyanya kusimba simba, yakanaka biocompatibility, uye inosimudzira kukura kwesero. Zvinoenderana nehupamhi hwemuviri wemutsara, inowanzobatwa kwemazuva 8-15, uye kunyura kwakagadzikana uye kwakavimbika, uye hapana mutsauko uri pachena wemunhu.
