PEEK Ankile

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 ziye zaxelwa. 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 iyakwazi ukuxutywa ngaphandle kokubangela nayiphi na impendulo njengoko i-ankile iyanyibilika.) Iindidi ezahlukeneyo ze-anchors ziye zaphuhliswa, kwaye i-designs of annchor iye yavela kule minyaka ilishumi idlulileyo ukwandisa ukusebenza kwabo ekudaleni ukulungiswa kwe-tendon-to-bone eqinile.

Polyetherketone

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

PEEK isiya isetyenziswa kakhulu kumacandelo e-tribological ngenxa yokusebenza kwayo okugqwesileyo. PEEK imathiriyeli ibonise ukomelela okuphezulu, iipropathi ezomeleleyo zoomatshini, ukunxiba kakuhle kunye nokumelana nobushushu, kunye nokuchaneka okugqwesileyo kweekhemikhali kunye nebhayoloji. Ngoko ke, inezinye izicelo ezininzi kubunjineli kunye neyeza.) PEEK ikwabonelela ngeenzuzo, ezifana nemifanekiso emihle emva kokusebenza kunye nokulungiswa okuzinzile, kwaye akukho zingxaki ezinxulumene nokuthotywa kwepolymer. Okubalulekileyo, eyona ngxaki inkulu nge- PEEK ibonakaliswe ikwi-osseointegration engalunganga. Ngokubanzi, nangona kunjalo, uphuhliso lwe-anchor ye- PEEK ikhokelele ekwamkelweni kwezixhobo ze-biocomposite ezinokuxhasa i-osteoconductive ingrowth.)

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 i-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 engabonakaliyo okanye zinezinga eliphantsi kakhulu lokuthotywa kwe-β-TCP (Fig).

ALL-SOFT ANCHOR SUTURE

Ii-ankile zohlobo oluqinileyo lwe-suture (umz., isinyithi kunye ne-polymer) ziye zaphononongwa 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 ii-anchors ezithambileyo ze-suture (ASAs) zaphuhliswa ukunciphisa iingxaki kunye nokuhlasela okunxulumene nokusetyenziswa kwee-ankile 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 kakhulu ngenxa yokunqongophala kwamathambo kwi-rim glenoid okanye i-acetabulum. Kwakhona, nokuba ukusilela kwe-ankile kwenzeka, umonakalo odibeneyo unokuncitshiswa ngenxa yomzimba we-ankile othambileyo.)
