PEEK Anchor

Dab tsi yog anchoring suture?

Suture anchors yog dav siv los txuas cov ntaub so ntswg (piv txwv li, tendons, ligaments, thiab meniscus) rau cov pob txha thiab tau dhau los ua cov cuab yeej tseem ceeb hauv cov tshuaj kis las thiab thaum phais arthroscopic. Raws li kev siv cov suture anchors tau nce, ntau yam khoom siv tshwj xeeb thiab cov teeb meem tau tshaj tawm. Raws li qhov tshwm sim, suture anchors tau hloov pauv tas li kom muaj kev nyab xeeb thiab ua haujlwm zoo dua. Nyob rau hauv ib puag ncig hloov pauv no, nws yog qhov tseem ceeb hauv kev kho mob rau tus kws phais kom nkag siab txog cov yam ntxwv tseem ceeb ntawm cov anchors uas twb muaj lawm txaus.

Kev siv cov suture anchors tau revolutionized orthopedic phais vim hais tias nws tso cai rau yooj yim thiab npaum fixation ntawm cov ntaub so ntswg (xws li, tendons thiab ligaments) rau cov pob txha nyob rau hauv ob qho tib si qhib thiab arthroscopic phais nyob ib ncig ntawm lub xub pwg nyom, luj tshib, dab teg, thiab qis ceg pob qij txha.) Lub xub pwg phais tshwj xeeb tshaj yog tau ntsib ib tug tseem ceeb kev hloov nyob rau hauv lub qhib hom kev kho mob cov tswv yim, siv cov kev kho mob ntawm lub xub pwg nyom. cov tshuab ntxhua khaub ncaws, transosseous sutures, thiab staples rau kho arthroscopic siv suture anchors.

Lub luag haujlwm tseem ceeb ntawm lub suture thauj tog rau nkoj yog muab cov ntaub so ntswg ntawm qhov chaw kom zoo thiab tuav nws txoj hauj lwm yam tsis muaj loosening los yog hnyav heev kom txog thaum lub cev kho tau tiav. Qhov zoo tshaj plaws suture thauj tog rau nkoj yog yooj yim los tuav, tuav kom txaus rub tawm lub zog, tiv thaiv suture abrasion, thiab yog absorbable yam tsis ua rau muaj kev cuam tshuam raws li cov khoom dissolves.) Ntau hom anchors tau tsim, thiab cov qauv tsim ntawm cov thauj tog rau nkoj tau hloov zuj zus nyob rau xyoo kaum tsis ntev los no los ua kom lawv cov txiaj ntsig zoo tshaj plaws hauv kev tsim kho kev ruaj khov-rau-bone.

Polyetheretherketone

Vim tias qee qhov biodegradable anchors tuaj yeem nqus tau sai heev, kev txhim kho ntawm biostable anchors tau ua raws. Xws li biostable thauj tog rau nkoj-polyetheretherketone (PEEK) polymer-yog tau los ntawm dialkylation ntawm bisphenol ntsev)

PEEK tau dhau los ua cov khoom siv hauv tribological vim nws qhov kev ua tau zoo heev. PEEK cov ntaub ntawv tau pom tias muaj zog, muaj zog txhua yam, zoo hnav-thiab kub-tiv taus, thiab zoo heev tshuaj lom neeg thiab lom. Yog li ntawd, nws muaj ntau lwm yam kev siv hauv engineering thiab tshuaj.) PEEK kuj muaj qhov zoo, xws li kev ua haujlwm zoo tom qab kev ua haujlwm zoo thiab ruaj khov kho, thiab tsis muaj teeb meem cuam tshuam nrog polymer degradation. Qhov tseem ceeb, qhov teeb meem loj nrog PEEK tau pom tias tsis zoo osseointegration. Zuag qhia tag nrho, txawm li cas los xij, kev txhim kho ntawm PEEK thauj tog rau nkoj tau coj mus rau kev siv cov khoom siv biocomposite uas tuaj yeem txhawb nqa osteoconductive ingrowth.)

BIOCOMPOSITE SUTURE ANCHOR

Biocomposite suture anchors yog tsim los ntawm ob qho tib si biodegradable polymer cov ntaub ntawv thiab cov pob txha tsim cov khoom siv bioceramic. Feem ntau siv bioceramic yog beta-tricalcium phosphate (β-TCP); Lwm tus muaj xws li hydroxyapatite, calcium sulfate, thiab calcium carbonate.) TCP yog dav siv hauv kev phais orthopedic los sau cov pob txha tsis xws luag vim (1) nws muaj cov ntxhia hauv cov pob txha zoo ib yam li tib neeg cov pob txha, (2) nws cov macro-porosity thiab micro-porosity yog osteoconductive, thiab (3) nws muaj biocompatibility zoo heev thiab mechanical resistance. Tsis zoo li β-TCP, hydroxyapatite yog ib yam khoom ntxhia ntuj uas muaj kev sib raug zoo rau cov pob txha thiab yog biocompatible heev vim nws zoo ib yam li cov pob zeb hauv cov hniav thiab cov pob txha ntawm cov tsiaj.) Feem ntau, hydroxyapatite-based pob txha hloov cov ntaub ntawv yog suav tias yog nonabsorbable los yog muaj tsawg dua degradation tus nqi tshaj β-TCP (Fig. 3)

TAG NRHO-SOFT SUTURE ANCHOR

Khoom hom suture anchors (piv txwv li, hlau thiab polymer) tau kawm ntau thiab pom tias muaj txaus rau kev tswj lub cev nyhav ntawm cov nqaij mos rau cov pob txha junctions. Feem ntau, cov khoom siv thauj tog rau nkoj no xav tau kev phais mob ntawm qhov chaw pob txha hneev taw (decortication, xuas nrig ntaus, lossis drilling) uas yuav ua rau cov pob txha poob vim yog qhov ntim hauv av.)

All-soft suture anchors (ASAs) tau tsim los txo cov teeb meem thiab kev cuam tshuam txog kev siv cov khoom siv thauj tog rau nkoj. Cov ASAs no muaj ib lossis ntau dua ultra-high-molecular-weight polyethylene (UHMWPE)-muaj sutures.

ASAs feem ntau muaj lub tes tsho los yog daim kab xev ua los ntawm cov khoom siv suture los ntawm UHMWPE-muaj suture yog woven. Qhov no fixation mechanism txawv piv nrog cov ntsia hlau hom suture anchors. Thaum ASA muab tso rau hauv cov pob txha thiab cov thawj suture yog rub, lub tes tsho los yog daim kab xev yog cinched mus rau compress tiv thaiv cov pob txha cortical overlying tsim ib 'pob' uas ua hauj lwm raws li lub thauj tog rau nkoj. Nws tso cai rau cov suture thauj tog rau nkoj muab tso rau hauv ib lub qhov me me (1-3 mm), yog li khaws cov pob txha thiab hypothetically tso cai rau cov pob txha khaws cia ntau dua, uas tej zaum yuav muaj txiaj ntsig tshwj xeeb vim muaj cov pob txha txwv ntawm glenoid ntug lossis acetabulum. Tsis tas li ntawd, txawm tias muaj qhov tsis ua haujlwm thauj tog rau nkoj, kev sib koom ua ke yuav raug txo kom tsawg vim yog lub cev pob txha mos.)
