I-PEEK iankile

Yintoni i-anchoring suture?

Ii-anchors ze-Suture zisetyenziselwa ngokubanzi ukunamathisela izicubu ezithambileyo (umzekelo, i-tendon, i-ligaments, kunye ne-meniscus) kwithambo kwaye ziye zaba zizixhobo ezibalulekileyo kumayeza ezemidlalo kunye nangexesha lotyando lwe-arthroscopic. Njengoko ukusetyenziswa kwee-ankile ze-suture kunyukile, izibonelelo ezahlukeneyo kunye nemingeni kuye kwachazwa. Ngenxa yoko, iiankile ze-suture zihlala zitshintsha ukuze zikhuseleke kwaye zisebenze ngakumbi. Kule meko isoloko iguquka, kuyimfuneko ngokweklinikhi ukuba ugqirha wotyando aqonde iimpawu eziphambili zeehange ezikhoyo ngokwaneleyo.

Ukusetyenziswa kwee-anchors ze-suture kuye kwaguqula utyando lwamathambo kuba luvumela ukulungiswa okulula kunye nokusebenzayo kwezicubu ezithambileyo (umzekelo, i-tendon kunye ne-ligaments) kwithambo kuzo zombini utyando oluvulekileyo kunye ne-arthroscopic ejikeleze igxalaba, i-elbow, wrist, kunye namalungu asezantsi.) i-sutures transosseous, kunye ne-staples ukulungiswa kwe-arthroscopic usebenzisa i-anchors ye-suture.

Umsebenzi oyintloko we-anchor ye-suture kukuncamathisela izicubu kwindawo efanelekileyo kwaye ugcine indawo yayo ngaphandle kokukhulula okanye ukuxhatshazwa ngokugqithiseleyo kuze kube yilapho ukuphulukiswa kwe-physiologic kufeziwe. I-anchor ye-suture efanelekileyo kulula ukuyiphatha, igcina amandla okwaneleyo okukhupha, inqanda i-suture abrasion, kwaye i-abrasion ngaphandle kokubangela nakuphi na ukusabela njengoko kunyibilika.

Polyetherketone

Ngenxa yokuba ezinye ii-ankile ezibolisiweyo zinokufunxwa ngokukhawuleza okukhulu, uphuhliso lweeankile ze-biostable lwalandelwa. I-anchor enjalo ye-biostable-i-polyetheretherketone (i-PEEK) i-polymer-ifunyenwe nge-dialkylation ye-bisphenol salts)

I-PEEK isanda ukusetyenziswa kumacandelo e-tribological ngenxa yokusebenza kwayo okugqwesileyo. Izinto ze-PEEK zibonise amandla aphezulu, iipropathi ezinamandla zoomatshini, ukunxiba kakuhle kunye nokumelana nobushushu, kunye nokuchasana kweekhemikhali kunye nebhayoloji. Ngoko ke, inezinye izicelo ezininzi kubunjineli kunye neyeza.) I-PEEK inika kwakhona izibonelelo, ezifana nemifanekiso emihle emva kokusebenza kunye nokulungiswa okuzinzile, kwaye akukho zingxaki ezinxulumene nokuthotywa kwepolymer. Okubalulekileyo, ingxaki enkulu nge-PEEK ibonakaliswe ukuba yi-osseointegration engalunganga. Ngokubanzi, nangona kunjalo, uphuhliso lwe-PEEK ianchor lukhokelele ekwamkelweni kwezixhobo ze-biocomposite ezinokuxhasa ukungena kwe-osteoconductive.)

I-BIOCOMPOSITE SUTURE ANCHOR

Ii-anchors ze-suture ze-Biocomposite zenziwe zizinto zombini ze-polymer eziphathekayo kunye nokwakheka kwethambo-ukukhuthaza imathiriyeli ye-bioceramic. I-bioceramic esetyenziswa ngokuqhelekileyo yi-beta-tricalcium phosphate (β-TCP); ezinye ziquka i-hydroxyapatite, i-calcium sulfate, kunye ne-calcium carbonate.) I-TCP isetyenziselwa ngokubanzi utyando lwamathambo ukuzalisa iziphene zamathambo kuba (1) inomxholo wamaminerali afana nethambo lomntu, (2) i-macro-porosity kunye ne-micro-porosity yi-osteoconductive, kwaye (3) ine-biocompatibility egqwesileyo kunye nokumelana nomatshini. Ngokungafani ne-β-TCP, i-hydroxyapatite yinto yendalo yamaminerali kunye ne-affinity emathanjeni kwaye i-biocompatible kakhulu kuba ifana necandelo lamaminerali lamazinyo kunye namathambo ezilwanyana ezincelisayo.) Ngokuqhelekileyo, izinto ezithatha indawo zethambo ze-hydroxyapatite zibhekwa njengento engenakuxhamla okanye zinezinga eliphantsi kakhulu lokuthotywa kwe-β-TCP (Fig).

ALL-SOFT ANCHOR SUTURE

Ii-ankile zohlobo oluqinileyo lwe-suture (umz., isinyithi kunye ne-polymer) zifundwe ngokubanzi kwaye zifunyenwe zanele ukugcina imithwalo ye-physiologic kwizicubu ezithambileyo ukuya kwiidibaniso zamathambo. Ngokwesiqhelo, ezi ankile zohlobo oluqinileyo zifuna ukulungiswa kotyando lwendawo yonyawo lwethambo (uhombiso, ukugqobhoza, okanye ukugrunjwa) okunokubangela ukulahleka kwamathambo ngenxa yomthamo wesiqwenga somhlaba.

Zonke-soft suture anchors (ASAs) zaphuhliswa ukunciphisa iingxaki kunye nokuhlasela okunxulumene nokusetyenziswa kweeankile zohlobo oluqinileyo. Ezi ASAs ziquka enye okanye ngaphezulu ultra-high-molekyuli-ubunzima polyethylene (UHMWPE)-eziqulathe sutures.

Ii-ASAs zibandakanya umkhono okanye iteyiphu eyenziwe ngemathiriyeli yokuthunga apho i-UHMWPE equlathe i-suture elukwa ngayo. Le ndlela yokulungisa iyahluka xa ithelekiswa ne-screw-type suture anchors. Xa i-ASA ifakwe kwithambo kunye ne-suture ephambili itsalwa, umkhono okanye i-tape igxilwe phezulu ukuze icinezele ithambo le-cortical elingaphezulu lidala 'ibhola' elisebenza njenge-ankile. Ivumela i-anchor ye-suture ukuba ifakwe kwi-tunnel kunye ne-diameter encinci (1-3 mm), ngaloo ndlela igcina ithambo kunye ne-hypothetically ivumela ukugcinwa kwamathambo amaninzi, anokuba luncedo ngakumbi ngenxa yokunqongophala kwamathambo kwi-rim glenoid okanye i-acetabulum. Kwakhona, nokuba ukusilela kwe-ankile kwenzeka, umonakalo odibeneyo unokuncitshiswa ngenxa yomzimba we-ankile othambileyo.)
