PEEK Anchor

Chii chinonzi anchoring suture?

Suture anchors anoshandiswa zvakanyanya kubatanidza zvinyoro zvinyoro (semu, tendon, ligaments, uye meniscus) kune bhonzo uye zvave zvakakosha mukurapa kwemitambo uye panguva yekuvhiya arthroscopic. Sezvo kushandiswa kwesuture anchors kwakawedzera, zvakasiyana-siyana-zvakanakira zvinhu uye matambudziko zvakataurwa. Nekuda kweizvozvo, suture anchors ari kuramba achichinja kuti ave akachengeteka uye anoshanda zvakanyanya. Munharaunda ino inogara ichichinja, zvakakosha zvekiriniki kuti chiremba anovhiya anzwisise maitiro akakosha ezvitsuwa zviripo zvakakwana.

Kushandiswa kwesuture anchors kwakashandura kuvhiyiwa kwemapfupa nokuti kunobvumira kugadzirisa nyore uye kwakanyatsogadziriswa kwezvinyama zvakapfava (semu, tendon uye ligaments) kune pfupa mune zvose zvakavhurika uye arthroscopic kuvhiyiwa pafudzi, gokora, wrist, uye majoini ezasi.) Kuvhiyiwa kwepafudzi kunonyanya kuve nekuchinja kukuru mumhando yemaitiro anoshandiswa kubva pakavhurika cuff, wabrus transosseous sutures, uye staples kune arthroscopic kugadzirisa uchishandisa suture anchors.

Basa rekutanga reiyo suture anchor ndeyekubatanidza matishu panzvimbo yakakodzera uye kuchengetedza chinzvimbo chayo pasina kusunungura kana kunyanyisa kushushikana kusvika physiologic kuporesa kwaitwa. Iyo yakanaka suture anchor iri nyore kubata, inochengetedza simba rakakwana rekudhonza-kunze, inodzivirira suture abrasion, uye inonyura pasina kukonzera chero maitiro sezvo zvinhu zvinonyungudika.) Mhando dzakasiyana-siyana dzeanchor dzakagadzirwa, uye magadzirirwo ezvibatiso akavepo mumakore gumi apfuura kuti awedzere kushanda kwawo mukugadzira yakasimba tendon-to-bhonzo kugadzirisa.

Polyetheretherketone

Nekuda kwekuti mamwe ma anchor anogona kunyudzwa nekukasira, kugadzira ma anchor e biostable akateedzerwa. Yakadaro biostable anchor- polyetheretherketone (PEEK) polymer-inowanikwa ne dialkylation ye bisphenol munyu)

PEEK iri kuwedzera kushandiswa muzvikamu zvetribological nekuda kwekuita kwayo kwakanaka. PEEK zvinhu zvakaratidza kusimba kwepamusoro, yakasimba mechanical zvivakwa, yakanaka kupfeka- uye kupisa-resistant, uye yakanakisa makemikari uye biological kuramba. Naizvozvo, ine mamwe akawanda maapplication muinjiniya nemishonga.) PEEK inopawo zvakanakira, seyakanaka postoperative imaging uye yakagadzikana kugadzirisa, uye hapana matambudziko ane chekuita nekuora kwepolymer. Zvakakosha, dambudziko guru nePEEK rakaratidzwa kuva rakashata osseointegration. Pakazere, zvisinei, kukwidziridzwa kwePEEK anchor kwakonzera kutorwa kwezvinhu zvebiocomposite zvinogona kutsigira osteoconductive ingrowth.)

BIOCOMPOSITE SUTURE ANCHOR

Biocomposite suture anchors inoumbwa nezvose zviri zviviri biodegradable polymer zvinhu uye bhonzo kugadzira-kusimudzira bioceramic zvinhu. Iyo inonyanya kushandiswa bioceramic ndeye beta-tricalcium phosphate (β-TCP); zvimwe zvinosanganisira hydroxyapatite, calcium sulfate, uye calcium carbonate.) TCP inoshandiswa zvakanyanya mukuvhiyiwa kwemapfupa kuzadza zvikanganiso zvemapfupa nokuti (1) ine mineral content yakafanana neyefupa revanhu, (2) macro-porosity uye micro-porosity is osteoconductive, uye (3) ine biocompatibility yakaisvonaka uye mechanical resistance. Kusiyana ne-β-TCP, hydroxyapatite inongova yemaminerari echisikigo ane affinity kumapfupa uye inonyanya kuenderana nehupenyu sezvo yakafanana nemaminerari echikamu chemazino nemapfupa emhuka dzinoyamwisa.) Kazhinji, hydroxyapatite-based bone substitute zvinhu zvinoonekwa sezvisingabviri kana kuva nekuderera kwakanyanya kudarika β-TCP (Fig).

ALL-SOFT SUTURE ANCHOR

Solid type suture anchors (semuenzaniso, simbi nepolymer) zvakadzidzwa zvakanyanya uye zvakaonekwa kuti zvinokwana kuchengetedza physiologic mitoro pazvinyoro zvinyoro kusvika kumajoini emapfupa. Kazhinji, aya akasimba mhando anchor anoda kuvhiyiwa kugadzirira kweiyo bony tsoka yetsoka (kushongedza, kubaya, kana kuchera) izvo zvinogona kukonzera kurasikirwa kwebhonzo nekuda kwehuwandu hwepasi.

All-soft suture anchors (ASAs) dzakagadzirwa kuti dzideredze kuomerwa uye kupindira zvine chekuita nekushandiswa kwemhando dzakasimba anchors. Aya maASA ane imwe kana anopfuura ekupedzisira-yepamusoro-soro-anorema polyethylene (UHMWPE)-ane sutures.

Iwo maASA anowanzo kuve ane sleeve kana tepi yakagadzirwa ne suture zvinhu iyo iyo UHMWPE-ine suture inorukwa. Iyi yekugadzirisa michina inosiyana kana ichienzaniswa nescrew-mhando suture anchors. Kana iyo ASA yaiswa mubhonzo uye yekutanga suture yakadhonzwa, sleeve kana tepi inosungirirwa kumusoro kuti isimbise pamusoro peiyo cortical bone yakapfuura ichigadzira 'bhora' rinoshanda sechibatiso. Inobvumira kuti suture anchor iiswe mumugero ane dhayamita diki (1-3 mm), nokudaro kuchengetedza pfupa uye nekufungidzira kubvumira mamwe mabhonzo ekuchengetedza, izvo zvingave zvakanyanya kubatsira nekuda kwekushomeka kwepfupa parimu glenoid kana acetabulum. Zvakare, kunyangwe kutadza kweancho kukaitika, kukuvadzwa kwemajoini kunogona kudzikiswa nekuda kwemuviri wakapfava weancho.)

The Ultimate Guide kune PEEK Anchors: Properties, Applications, uye Advantages

Kana iwe uchitsvaga chinhu chinogona kupa simba repamusoro, kuoma, uye makemikari kuramba, PEEK (polyetheretherketone) ndiyo sarudzo yakakwana. PEEK ndeyepamusoro-inoita polymer iyo yave nemukurumbira mumaindasitiri mazhinji nekuda kweayo emhando yemakina zvivakwa, biocompatibility, uye kugadzikana kwekupisa.
