M'munda wa opaleshoni, kusankha suture kumathandiza kwambiri kuonetsetsa chitetezo cha odwala komanso kuchira bwino. Pakati pa zosankha zosiyanasiyana zomwe zilipo, ma sutures opangira opaleshoni, makamaka osabala omwe sangatengeke, apeza chidwi chifukwa cha kudalirika kwawo komanso kugwira ntchito kwawo. Ma sutures awa adapangidwa kuti azipereka chithandizo chokhalitsa ku minofu, kuwapangitsa kukhala abwino kwa maopaleshoni omwe amafunikira mphamvu yayitali yayitali.

Chimodzi mwazinthu zodziwika bwino zomwe zimagwiritsidwa ntchito popanga ma sutures osayamwa osayamwa ndi ultra-high molecular weight polyethylene (UHMWPE). Thermoplastic yapamwamba iyi imakhala ndi maunyolo aatali kwambiri a mamolekyu, omwe amakhala kuyambira 3.5 mpaka 7.5 miliyoni amu. Mapangidwe apadera a UHMWPE amakulitsa luso lake lotumiza katundu bwino, potero kumalimbitsa kulumikizana kwa ma intermolecular. Zotsatira zake, nkhaniyi ikuwonetsa kulimba kosayerekezeka komanso mphamvu yayikulu kwambiri pakati pa ma thermoplastics, zomwe zimapangitsa kukhala chisankho chabwino kwambiri pama opaleshoni pomwe kulimba ndikofunikira.

Ku WEGO, timanyadira popereka zida zachipatala zambiri, kuphatikiza ma sutures opitilira 1,000 osabala. Zogulitsa zathu zimapangidwa mosamala kupitilira 150,000, kuwonetsetsa kuti akatswiri azachipatala alandila zida zapamwamba kwambiri. Pogwiritsa ntchito magawo 11 mwa magawo 15 amsika, WEGO yakhala wodalirika padziko lonse wopereka mayankho pamachitidwe azachipatala, odzipereka kukonza zotulukapo za opaleshoni kudzera mwaukadaulo komanso kudalirika.

Mwachidule, kuphatikiza kwa ultrahigh molekyulu yolemera polyethylene mu ma sutures osayamwa osayamwa kumayimira kupita patsogolo kwaukadaulo wa opaleshoni. Pamene tikupitiriza kukankhira malire a luso lachipatala, WEGO ikupitirizabe kupatsa akatswiri azaumoyo zida zomwe amafunikira kuti apereke chisamaliro chapadera cha odwala. Tsogolo la opaleshoni yolondola tsopano, yomangidwa pa khalidwe, chitetezo ndi ntchito.
