I-PEEK Anchor

Iyini i-anchoring suture?

Amahange e-Suture asetshenziswa kabanzi ukunamathisela izicubu ezithambile (isb., imisipha, imigqa, ne-meniscus) ethanjeni futhi abe yimishini ebalulekile emithini yezemidlalo nangesikhathi sokuhlinzwa kwe-arthroscopic. Njengoba ukusetshenziswa kwamahange we-suture kuye kwanda, izinzuzo nezinselele ezihlukahlukene eziqondene nezinto ezithile ziye zabikwa. Ngenxa yalokho, amahange e-suture ahlala eshintsha ukuze aphephe futhi asebenze kahle. Kule ndawo ehlala ishintsha, kubalulekile ngokomtholampilo ukuthi udokotela ohlinzayo aqonde izici ezibalulekile zamahange akhona ngokwanele.

Ukusetshenziswa kwamahange e-suture kuye kwashintsha ukuhlinzwa kwamathambo ngoba kuvumela ukulungiswa okulula nangempumelelo kwezicubu ezithambile (isb., imisipha nemigqa) ethanjeni kukho kokubili ukuhlinzwa okuvulekile kanye nokuhlinzwa kwe-arthroscopic ehlombe, indololwane, isihlakala, namalunga ezitho ezingezansi.) Ukuhlinza ihlombe ikakhulukazi kuye kwaba noshintsho oluphawulekayo ohlotsheni lwamasu asetshenziswa kusukela ekulungisweni kwe-open rotamsher ne-wabru i-transosseous sutures, kanye nezinto eziyisisekelo zokulungiswa kwe-arthroscopic kusetshenziswa amahange we-suture.

Umsebenzi oyinhloko wehange le-suture ukunamathisela izicubu endaweni efanele futhi ugcine isikhundla saso ngaphandle kokuxega noma ukucindezeleka ngokweqile kuze kufezwe ukuphulukiswa kwe-physiologic. Ihange elifanelekile liphathwa kalula, ligcina amandla anele okudonsa, livimbela ukuhuzuka kwe-suture, futhi liyamunceka ngaphandle komphumela wanoma yikuphi ukusabela njengoba impahla incibilika.) Izinhlobo ezihlukahlukene zamahange ziye zathuthukiswa, futhi imiklamo yamahange iye yavela phakathi neshumi leminyaka elisanda kwedlula ukuze kwandiswe ukusebenza kwayo kahle ekudaleni ukulungiswa okuqinile kwe-tendon kuya ethanjeni.

I-Polyetherketone

Ngenxa yokuthi amanye amahange abolayo angamuncwa ngokushesha okukhulu, ukwakhiwa kwamahange e-biostable kwaqhutshwa. I-biostable anchor enjalo-i-polyetheretherketone (PEEK) i-polymer-itholakala ngokukhipha usawoti we-bisphenol )

I-PEEK iya ngokuya isetshenziswa ezingxenyeni ze-tribological ngenxa yokusebenza kwayo okuhle kakhulu. Izinto ze-PEEK zibonise amandla aphezulu, izakhiwo eziqinile zemishini, ukugqoka okuhle nokumelana nokushisa, nokumelana okuhle kakhulu kwamakhemikhali nokokuphila. Ngakho-ke, inezinye izinhlelo zokusebenza eziningi kwezobunjiniyela nakwezokwelapha.) I-PEEK iphinde inikeze izinzuzo, ezifana nesithombe esihle se-postoperative kanye nokulungiswa okuzinzile, futhi azikho izinkinga ezihlobene nokuwohloka kwe-polymer. Okubalulekile, inkinga enkulu nge-PEEK ikhonjiswe njengokungahlangani kahle kwe-osseo. Sekukonke, nokho, ukuthuthukiswa kwe-PEEK anchor kuye kwaholela ekwamukelweni kwezinto ezibonakalayo ezingase zisekele ukungena kwe-osteoconductive.)

I-BIOCOMPOSITE SUTURE ANCHOR

Amahange we-Biocomposite suture akhiwe yikho kokubili i-biodegradable polymer material kanye ne-bone formation-promoting bioceramic material. I-bioceramic esetshenziswa kakhulu yi-beta-tricalcium phosphate (β-TCP); ezinye zihlanganisa i-hydroxyapatite, i-calcium sulfate, ne-calcium carbonate.) I-TCP isetshenziswa kabanzi ekuhlinzweni kwamathambo ukuze kugcwaliswe ukukhubazeka kwamathambo ngoba (1) inokuqukethwe kwamaminerali okufana nethambo lomuntu, (2) i-macro-porosity yayo kanye ne-micro-porosity i-osteoconductive, futhi (3) ine-biocompatibility enhle kakhulu kanye nokumelana nomshini. Ngokungafani ne-β-TCP, i-hydroxyapatite iyinto yamaminerali yemvelo ehambisana namathambo futhi ihambisana kakhulu ne-biocompatible ngoba ifana nengxenye yamaminerali yamazinyo namathambo ezilwane ezincelisayo.) Ngokuvamile, izinto ezithatha indawo yamathambo ezisekelwe ku-hydroxyapatite zibhekwa njengezingenakulinganiswa noma zinezinga eliphansi kakhulu lokuwohloka kune-β-TCP (Fig).

ALL-SOFT SUTURE ANCHOR

Amahange ohlobo oluqinile lwe-suture (isb., insimbi ne-polymer) acutshungulwe kakhulu futhi atholakala enele ukugcina imithwalo ye-physiologic ezicutshini ezithambile kuya ekuhlanganeni kwethambo. Ngokuvamile, lezi zikhonkwane zohlobo oluqinile zidinga ukulungiswa kokuhlinzwa kwendawo yokunyathelisa yethambo (ukuhlobisa, ukubhoboza, noma ukubhoboza) okungase kubangele ukulahleka kwamathambo ngenxa yomthamo wesiqephu esiphansi.)

Amahange e-All-soft suture (ASAs) athuthukiswe ukuze kuncishiswe izinkinga nokuhlasela okuhlobene nokusetshenziswa kwamahange ohlobo oluqinile. Lawa ma-ASA aqukethe eyodwa noma ngaphezulu i-ultra-high-molecular-weight polyethylene (UHMWPE)-equkethe umshudo.

Ama-ASA ngokuvamile ahlanganisa umkhono noma itheyiphu eyenziwe ngezinto zokuthunga lapho i-suture equkethe i-UHMWPE elukwa ngayo. Le ndlela yokulungisa iyahluka uma iqhathaniswa namahange e-screw-suture suture. Uma i-ASA ishuthekwa ethanjeni futhi i-suture eyinhloko idonswa, umkhono noma itheyiphu iyacindezelwa ukuze iminyaniswe nethambo le-cortical elingaphezu kwamandla okwenza 'ibhola' elisebenza njengehange. Ivumela ihange le-suture ukuba libekwe emhubheni onobubanzi obuncane (1-3 mm), ngaleyo ndlela ilondoloze amathambo futhi ivumele ngokomqondo ukulondolozwa kwamathambo engeziwe, okungase kube nenzuzo ikakhulukazi ngenxa yokulinganiselwa kwamathambo onqenqemeni lwe-glenoid noma i-acetabulum. Futhi, ngisho noma kwenzeka ukuhluleka kwehange, ukulimala okuhlangene kungase kuncishiswe ngenxa yomzimba wehange othambile.)

Umhlahlandlela Wokugcina Wezikhonkwane ze-PEEK: Izakhiwo, Izinhlelo zokusebenza, kanye Nezinzuzo

Uma ufuna into enganikeza amandla aphakeme, ukuqina, nokumelana namakhemikhali, i-PEEK (i-polyetheretherketone) iyisinqumo esihle kakhulu. I-PEEK i-polymer esebenza kahle kakhulu eseyidumile ezimbonini eziningi ngenxa yezakhiwo zayo ezivelele zemishini, i-biocompatibility, kanye nokuzinza kwe-thermal. Kulesi sihloko, sizoxoxa ngamahange e-PEEK, izakhiwo zawo, izinhlelo zokusebenza, kanye nezinzuzo.

Ayini ama-PEEK Anchors?

Amahange e-PEEK ayizixhumi ezenziwe ngezinto ze-PEEK ezidizayinelwe ukuhlinzeka ngezikhonkwane eziqinile nezithembekile ezinhlelweni zokusebenza ezahlukahlukene. Zivame ukusetshenziswa embonini yezokwelapha, i-aerospace, yezimoto, kanye nekawoyela negesi, phakathi kokunye. Amahange e-PEEK aziwa ngokukwazi kwawo ukumelana nemithwalo ephezulu, ukushintsha kwezinga lokushisa, kanye nezindawo ezinokhahlo.

Izakhiwo ze-PEEK Anchors

Amahange e-PEEK anezakhiwo eziningi eziwenza abe phezulu kunezinye izinto. Ezinye zezakhiwo eziphawuleka kakhulu zamahange e-PEEK zifaka:

Amandla Aphezulu Nokuqina

Amahange e-PEEK anamandla amakhulu okuqina kanye nokuqina, okuwenza alungele izinhlelo zokusebenza ezidinga ukubambelela okuqinile nokuthembekile. Bangakwazi ukumelana nemithwalo ephezulu kanye nomthelela ngaphandle kokuphuka noma ukukhubazeka.

Ukumelana Kwamakhemikhali

Amahange e-PEEK amelana kakhulu namakhemikhali amaningi, afaka ama-asidi, izisekelo, nezinyibilikisi zemvelo. Lokhu kuzenza zilungele izinhlelo zokusebenza lapho kulindeleke khona ukuchayeka kumakhemikhali anonya.

Ukuzinza Okushisayo

Amahange e-PEEK anokuqina okuhle kakhulu kokushisa, amelana nezinga lokushisa elifinyelela ku-300°C ngaphandle kokuncibilika noma ukuwohloka. Ziyakwazi futhi ukumelana namazinga okushisa abandayo, okuzenza zilungele ukusetshenziswa ezinhlelweni ze-cryogenic.

I-Biocompatibility

Amahange e-PEEK ahambisana ne-biocompatible, okuwenza aphephe ukusetshenziswa ezinhlelweni zezokwelapha nezamazinyo. Futhi ayinabo ubuthi futhi ayiyona i-carcinogenic, okwenza kube inketho evumelana nemvelo.

Izicelo ze-PEEK Anchors

Amahange e-PEEK anohlu olubanzi lwezinhlelo zokusebenza, okuhlanganisa:

Izicelo Zezokwelapha Nezamazinyo
