Kubathengi abafuna ama-MOQ aphansi kanye nezinhlobonhlobo zemikhiqizo ephezulu, abaphakeli be-Multispecialty banikeza ukwenza ngokwezifiso kwe-MOQ ephansi, izixazululo ze-logistics kusukela ekuqaleni kuya ekugcineni, kanye nokuthengwa kwezigaba eziningi, okusekelwa ulwazi lwabo olucebile embonini kanye nensizakalo kanye nokuqonda okuqinile kwezitayela zomkhiqizo ezisafufusa.
Ⅰ. Ziyini izikulufo ze-PEEK?
Izikulufu ze-PEEK (polyetheretherketone) zenziwe ngepulasitiki yobunjiniyela ekhethekile enokushisa okuhle kakhulu, ukumelana nokugqwala, ukumelana nokushisa okuphezulu, kanye nokumelana nomlilo. Zisetshenziswa kabanzi kumadivayisi ezokwelapha, imishini kagesi, izindiza, nakweminye imikhakha.
Izakhiwo Zezinto
I-PEEK iyipulasitiki ekhethekile yobunjiniyela e-semi-crystalline enokumelana okuhle kwamakhemikhali phakathi kwamapulasitiki obunjiniyela, encibilika kuphela ku-sulfuric acid egxilile. Izakhiwo zayo zobuchwepheshe zifaka phakathi ukumelana nokushisa (izinga lokushisa lokusebenza eliqhubekayo kufika ku-260°C), ukumelana nokuguguleka, ukumelana nokushisa komlilo (UL94 V-0 flame retardancy), kanye nokumelana ne-hydrolysis.
Izicelo
Amadivayisi Ezokwelapha: Ngenxa yezakhiwo zawo ezingezona ezikagesi, ezivikela ukushisa, kanye nezingagqwali, afanelekela izingxenye zezinsimbi zokuhlinza.
Amadivayisi E-elekthronikhi: Asetshenziswa ezingxenyeni ezinembile njengezithwali ze-IC wafer kanye nama-jig okukhiqiza e-LCD.
Izindiza: Isetshenziswa kakhulu ezinhlotsheni ezidinga amandla njengemishini yamandla omoya kanye nezimpawu zomnyango wendiza.
Izinhlobo Zokwakha
Amanye amamodeli aqiniswa nge-glass fiber (isb., i-glass fiber engu-30%) ukuze kuthuthukiswe izakhiwo zemishini. Avame ukusetshenziswa ezakhiweni ezibunjwe ngendlela ekhethekile njengezikulufo ze-hermaphroditic kanye nezikulufo zesithupha ezigoqiwe.
Ⅱ. Ingabe bafaka izikulufo edolweni lakho ukuze bahlinzwe i-ACL?
Izikulufo zivame ukusetshenziselwa ukubopha izingcezu ngesikhathi sokuhlinzwa kokwakhiwa kabusha kwe-anterior cruciate ligament (ACL). Ngesikhathi sokwakhiwa kabusha kwe-ACL, udokotela ohlinzayo usebenzisa i-arthroscopy ukwenza izimbobo ezincane ezizungeze ijoyinti ledolo. Ngemva kokususa i-ACL eyonakele, i-autologous noma i-allogeneic graft ifakwa ejoyintini. Izikulufo, ama-anchor, namanye amadivayisi asetshenziselwa ukubopha i-graft embhedeni wethambo ukuze kuqiniswe.
Inhloso Yezikulufo
Izikulufo zisetshenziswa kakhulu ukuqinisa izingcezu zokufakelwa (njenge-patellar tendon kanye ne-hamstring tendon) ku-femur kanye ne-tibia, ukuvimbela ukuthi zingasheleli noma ziwe. Lolu hlobo lokuqinisa luyinqubo evamile ngesikhathi sokuhlinzwa kwe-arthroscopic futhi luqinisekisa ukuqina kwedolo ngemva kokuhlinzwa.
Izinyathelo Zokuqapha Ngemva Kokuhlinzwa
Ngemva kokuhlinzwa, kudingeka i-brace noma izinduku zokubambelela ukuze kuvikelwe idolo, futhi kwenziwa ukwelashwa ngokomzimba kanye nokuzivocavoca kokuvuselelwa. Ngokuvamile izikulufo azidingi ukususwa; kancane kancane ziba yingxenye yethambo njengoba amathambo ehlangana.
Ⅲ.Ingabe isikulufu se-PEEK singabola?
Izikulufo ze-polyetheretherketone (PEEK) aziboli. Ngenxa yezakhiwo zazo ezibonakalayo, azikwazi ukubola ngokwemvelo emzimbeni womuntu futhi zidinga ukususwa ngokuhlinzwa.
Izizathu Zokungaboli Kwemvelo
I-PEEK (i-polyetheretherketone) iyi-polymer enesisindo sama-molecule aphezulu ebonakala ngamandla aphezulu kanye nokuqina. Ayikwazi ukuwohloka emzimbeni womuntu ngokuwohloka kwe-enzyme noma ukugqwala. Ezisetshenzisweni zezokwelapha zamanje, izikulufo ze-PEEK zisetshenziswa kakhulu ekuvuselelweni kabusha kwe-anterior cruciate ligament kanye nokuhlinzwa kwe-joint fusion, okudinga ukuqina kwethambo noma izicubu ezithambile isikhathi eside. Ngakho-ke, izinto kumele zibonise ukuzinza kwesikhathi eside.
