Ndi CAH Medical | Sichuan, China
Kwa ogula omwe akufunafuna ma MOQ otsika komanso mitundu yambiri yazogulitsa, Multispecialty Suppliers amapereka masinthidwe otsika a MOQ, mayankho amtundu wakumapeto, ndi kugula kwamitundu yambiri, mothandizidwa ndi mafakitale awo olemera komanso luso lantchito komanso kumvetsetsa kwamphamvu kwazomwe zikubwera.
Ⅰ.Kodi zomangira za PEEK ndi chiyani?
Zomangira za PEEK (polyetheretherketone) amapangidwa kuchokera ku pulasitiki yaukadaulo yapadera yokhala ndi zotsekera bwino, kukana dzimbiri, kukana kutentha kwambiri, komanso kuchedwa kwamoto. Amagwiritsidwa ntchito kwambiri pazida zamankhwala, zida zamagetsi, zakuthambo, ndi zina.
Zinthu Zakuthupi
PEEK ndi pulasitiki yaukadaulo wapamwamba kwambiri yomwe ili ndi mphamvu yabwino kwambiri yokana mankhwala pakati pa mapulasitiki auinjiniya, yomwe imasungunuka mu sulfuric acid wokhazikika. Zomwe zimapangidwira zimaphatikizira kukana kutentha (kutentha kosalekeza mpaka 260 ° C), kukana kuvala, kuzizira kwamoto (UL94 V-0 retardancy yamoto), komanso kukana kwa hydrolysis.
Mapulogalamu
Zida Zachipatala: Chifukwa cha zinthu zomwe sizikhala ndi maginito, zoteteza, komanso zosagwira dzimbiri, ndizoyenera zida zopangira opaleshoni.
Zipangizo Zamagetsi: Zogwiritsidwa ntchito muzinthu zolondola monga zonyamulira za IC wafer ndi ma LCD opanga ma jigs.
Zamlengalenga: Zomwe zimagwiritsidwa ntchito movutikira monga zida zamagetsi zamagetsi ndi zisindikizo zapakhomo la ndege.
Mitundu Yomanga
Mitundu ina imalimbikitsidwa ndi ulusi wagalasi (mwachitsanzo, 30% ulusi wagalasi) kuti uwonjezere mphamvu zamakina. Amagwiritsidwa ntchito kwambiri popanga zomangika mwapadera monga zomangira za hermaphroditic ndi zomangira zopindika.
Ⅱ.Kodi amaika zomangira pabondo pa opaleshoni ya ACL?
Zomangira zimagwiritsidwa ntchito nthawi zambiri kuti zitetezedwe panthawi ya opaleshoni yomanganso ya anterior cruciate ligament (ACL). Panthawi yomanganso ACL, dokotala wa opaleshoni amagwiritsa ntchito arthroscopy kuti apange pang'ono pozungulira mawondo. Pambuyo pochotsa ACL yowonongeka, autologous kapena allogeneic graft imayikidwa mu mgwirizano. Screws, anangula, ndi zida zina zimagwiritsidwa ntchito kuti atetezedwe ku bedi la fupa kuti likhale lokhazikika.
Cholinga cha Screws
Zopangira zida zimagwiritsidwa ntchito kuti zisungidwe bwino (monga patellar tendon ndi hamstring tendon) kupita ku femur ndi tibia, kuwateteza kuti asagwere kapena kugwa. Kukonzekera kotereku ndi njira yodziwika bwino pa opaleshoni ya arthroscopic ndipo imatsimikizira kukhazikika kwa mawondo pambuyo pa opaleshoni.
Chitetezo cha Postoperative
Pambuyo pa opaleshoni, chingwe kapena ndodo zimafunika kuti ziteteze mgwirizano wa bondo, ndipo masewero olimbitsa thupi ndi kukonzanso amachitidwa. Nthawi zambiri zomangira sizifunika kuchotsedwa; iwo pang’onopang’ono amakhala mbali ya fupa pamene mafupa amalumikizana.
Ⅲ.Kodi PEEK screw biodearadable?
Zomangira za polyetheretherketone (PEEK) siziwola. Chifukwa cha zinthu zawo zakuthupi, sangathe kuwonongeka mwachibadwa m'thupi la munthu ndipo amafuna kuchotsedwa opaleshoni.
Zifukwa Zosagwirizana ndi Biodegradability
PEEK (polyetheretherketone) ndi polima wolemera kwambiri wodziwika ndi mphamvu zambiri komanso kukhazikika. Sizingawonongeke m'thupi la munthu chifukwa cha kuwonongeka kwa enzymatic kapena dzimbiri. M'machitidwe azachipatala apano, zomangira za PEEK zimagwiritsidwa ntchito makamaka pakumanganso minyewa yam'mbuyo ndi maopaleshoni ophatikizika, omwe amafunikira kukonza kwanthawi yayitali kwa mafupa kapena minofu yofewa. Chifukwa chake, zinthuzo ziyenera kuwonetsa kukhazikika kwanthawi yayitali.
