Pali mapazi angapo omwe amagwiritsidwa ntchito kawirikawiri: mapazi a static, mapazi a uniaxial, mapazi osungira mphamvu, mapazi osasunthika, mapazi a carbon fiber, etc. Mtundu uliwonse wa phazi ndi woyenera kwa anthu osiyanasiyana, ndipo zinthu zambiri ziyenera kuganiziridwa posankha prosthesis. , monga zaka za wodwalayo, kutalika kwa ntchafu yotsalira, mphamvu yolemetsa yotsalira, komanso ngati bondo liri lokhazikika ngati ntchafu yadulidwa, ndi malo ozungulira.Chilengedwe, ntchito, luso lazachuma, mikhalidwe yosamalira, ndi zina.
Lero, ndikuwonetsa mapazi awiri opangira ma prosthetic omwe ali ndi mtengo wokwera kwambiri.
(1) KUPANDA KUPANDA
Mapazi a SACH ali ndi zidendene zofewa za akakolo.Bondo lake ndi chigawo chake chapakati ndi chapakati, chophimbidwa ndi thovu ndi chooneka ngati phazi.Chidendene chake chimakhala ndi mpeni wofewa wa pulasitiki, womwe umatchedwanso chidendene chofewa.Pa kugunda kwa chidendene, chidendene chofewa chimapunduka pansi pa kukanikiza ndipo kenako chimakhudza pansi, mofanana ndi phazi la plantar.Pamene phazi loikidwiratu likupitirirabe kutsogolo, kusuntha kwa mbali ya kutsogolo kwa chipolopolocho kumayandikira kufalikira kwa dorsal kwa chala.Kuyenda kwa phazi la prosthetic mu ndege yopanda mawonekedwe kumatheka ndi zinthu zotanuka pamapazi.
Mapazi a SACH ndi opepuka kulemera kwake.Itha kugwiritsidwanso ntchito popanga miyendo yaying'ono yokhala ndi zotsatira zabwino.Pogwiritsidwa ntchito popanga ntchafu, ndizoyenera kwa odwala omwe amayenda pamtunda kapena odwala m'madera omwe ali ndi zinthu zosavuta.Kuyenda kosinthasintha kwa phazi kumangokhalira chidendene ndi metatarsophalangeal joints, ndipo alibe ntchito zosinthika ndi zozungulira.Pamene kutalika kwa kudulidwa kumawonjezeka ndipo zovuta za mtunda zikuwonjezeka, phazi limakhala losayenerera.Kuonjezera apo, kukhazikika kwa mgwirizano wa bondo kumakhudzidwanso kwambiri chifukwa cha kukhazikika kwa kutsetsereka.
(2) Phazi Limodzi la Axis
Phazi la uniaxial limakhala ndi nsonga yolumikizana ndi phazi la munthu.Phazi limatha kuchita dorsiflexion ndi plantarflexion mozungulira mozungulira.Mapangidwe a phazi amatsimikiziranso kuti akhoza kungoyenda mu ndege yopanda pake.Kuyenda kosiyanasiyana ndi kunyowa kwa dorsiflexion ndi kupendekeka kwa plantar kwa phazi la uniaxial kungasinthidwe pogwiritsa ntchito zipangizo zamakono zomwe zili kutsogolo ndi kumbuyo kwa shaft.Amakhalanso ndi gawo lokhazikika la mgwirizano wa bondo.Kuipa kwa phazi lamtundu uwu ndi lolemera, logwiritsidwa ntchito kwa nthawi yaitali kapena losauka, ndipo zolumikizira zatha.
