PEEK Ihange

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 ne-arthroscopic ehlombe, indololwane, isihlakala, namalunga angaphansi.) Ukuhlinzwa kwehlombe ikakhulukazi kuye kwaba noshintsho oluphawulekayo ohlotsheni lwamasu asetshenziswa kusukela ekulungisweni kwe-rotamsher evulekile, isikulufu se-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 sawo 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 zenziwe, 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 nge-dialkylation yama-bisphenol salts)

PEEK iya ngokuya isetshenziswa ezingxenyeni ze-tribological ngenxa yokusebenza kwayo okuhle kakhulu. PEEK izinto ezisetshenziswayo zibonise amandla aphezulu, izakhiwo eziqinile zemishini, ukuguga okuhle nokumelana nokushisa, nokumelana okuhle kwamakhemikhali nokokuphila. Ngakho-ke, inezinye izinhlelo zokusebenza eziningi kwezobunjiniyela nezokwelapha.) PEEK iphinde inikeze izinzuzo, ezifana nesithombe esihle sangemva kokuhlinzwa nokulungiswa okuzinzile, futhi azikho izinkinga ezihlobene nokuwohloka kwe-polymer. Okubalulekile, inkinga enkulu nge PEEK iboniswe njenge-osseointegration empofu. Sekukonke, nokho, ukuthuthukiswa kwe-anchor ye PEEK kuholele ekwamukelweni kwezinto ezibonakalayo ze-biocomposite 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 evame ukusetshenziswa 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 njengezingenakunyakaziswa 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. Imvamisa, lawa mahange ohlobo oluqinile adinga ukulungiswa kokuhlinzwa kwendawo yethambo lezinyawo (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 kokwenza 'ibhola' elisebenza njengehange. Ivumela ihange le-suture ukuthi 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 We- PEEK Amahange: Izakhiwo, Izinhlelo zokusebenza, kanye Nezinzuzo

Uma ufuna into enganikeza amandla aphakeme, ukuqina, nokumelana namakhemikhali, 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 PEEK ngamahange, izakhiwo zawo, izinhlelo zokusebenza, kanye nezinzuzo.

Ayini PEEK Amahange?

PEEK amahange ayizixhumi ezenziwe PEEK ngezinto ezidizayinelwe ukuhlinzeka okuqinile nokuthembekile ezinhlelweni zokusebenza ezihlukahlukene. Zivame ukusetshenziswa embonini yezokwelapha, i-aerospace, yezimoto, kanye nekawoyela negesi, phakathi kokunye. PEEK amahange aziwa ngokukwazi kwawo ukumelana nemithwalo ephezulu, ukushintsha kwezinga lokushisa, kanye nezindawo ezinokhahlo.

Izakhiwo Ze- PEEK Amahange

PEEK amahange anezinto eziningi eziwenza aphakame kunezinye izinto. Ezinye zezinto eziphawuleka kakhulu zamahange e PEEK zifaka:

Amandla Aphezulu Nokuqina

PEEK amahange anamandla okunyakazisa okuphezulu nokuqina, okuwenza alungele izinhlelo zokusebenza ezidinga ukubambelela okuqinile nokuthembekile. Bangakwazi ukumelana nemithwalo ephezulu kanye nomthelela ngaphandle kokuphuka noma ukukhubazeka.

Ukumelana Kwamakhemikhali

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

Ukuzinza Okushisayo

PEEK Izikhonkwane zinokuzinza okuhle kakhulu kwe-thermal, zimelana nezinga lokushisa elifika ku-300°C ngaphandle kokuncibilika noma ukwehlisa izinga. Ziyakwazi futhi ukumelana namazinga okushisa abandayo, okuzenza zilungele ukusetshenziswa ezinhlelweni ze-cryogenic.

I-Biocompatibility

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

Izinhlelo zokusebenza ze PEEK Amahange

PEEK amahange anezinhlobonhlobo zezinhlelo zokusebenza, okuhlanganisa:
