Kukho iinyawo ezininzi ezisetyenziswa ngokuqhelekileyo: iinyawo ze-static, iinyawo ze-uniaxial, iinyawo zokugcina amandla, iinyawo ezingatyibilikiyo, iinyawo ze-carbon fiber, njl njl. , njengobudala bomguli, ubude belungu elishiyekileyo, amandla okuthwala ubunzima belungu elishiyekileyo, nokuba idolo lizinzile ukuba kukunqunyulwa kwethanga, kunye nommandla ojikelezayo.Okusingqongileyo, umsebenzi, isakhono sezoqoqosho, iimeko zokulondoloza, njl.
Namhlanje, ndiza kwazisa iinyawo ezimbini zokufakelwa kunye nokusebenza kweendleko eziphezulu.
(1) UNYAWO OLUMHLAKA
Iinyawo ze-SACH zizithende ezithambileyo zeqatha.I-ankle kunye ne-midsection yayo yenziwe ngumbindi wangaphakathi, ogqunywe ngamagwebu kwaye ufana nonyawo.Isithende sayo sixhotyiswe ngeplastiki ethambileyo yegwebu, ebizwa ngokuba sisithende esithambileyo.Ngethuba lokubethelwa kwesithende, isithende esithambileyo siphazamisa phantsi koxinzelelo kwaye emva koko sithinte umhlaba, kufana ne-plantar flexion yonyawo.Njengoko unyawo olufakelwayo luqhubeka luqengqelekela phambili, ukuhamba kwenxalenye engaphambili yeqokobhe logwebu kusondela kukwandiswa komqolo wenzwane.Ukuhamba kweenyawo zeprosthetic kwinqwelo-moya engeyiyo ifumaneka ngezinto ezi-elastic ezinyaweni.
Iinyawo ze-SACH zikhaphukhaphu ngobunzima.Inokusetyenziswa kwakhona kwiiprotheses zomlenze omncinci kunye neziphumo ezilungileyo.Xa isetyenziselwa i-prosthesis yethanga, ifanelekile kuphela kwizigulane ezihamba phantsi komhlaba okanye izigulane kwiindawo ezineemeko ezilula.Ukunyakaza okuguquguqukayo kweenyawo kunqunyelwe kwisithende kunye ne-metatarsophalangeal joints, kwaye ayinayo imisebenzi yokuguqula kunye nokujikeleza.Njengoko ukuphakama kokunqunyulwa kwanda kwaye ubunzima bomhlaba buyanda, unyawo luba lufanelekile.Ukongezelela, ukuzinza kwamadolo adibeneyo kuchaphazeleka kakubi ngenxa yokuqina kokufika.
(2) I-Axis Foot enye
Unyawo lwe-uniaxial lune-articulation axis enxulumene ne-ankle joint.Unyawo lunokwenza i-dorsiflexion kunye ne-plantarflexion ngeenxa zonke kule axis.Ulwakhiwo lonyawo lukwamisela ukuba lunokuhamba kuphela kwinqwelomoya engeyonto encinci.Uluhlu lokunyakaza kunye nokuthotywa kwe-dorsiflexion kunye ne-plantar flexion yonyawo lwe-uniaxial lunokulungelelaniswa ngokusebenzisa izixhobo zokukhusela ezibekwe ngaphambili nangasemva kwe-shaft.Baphinde badlale indima ekuzinzeni kwamadolo.Ukungalungi kolu hlobo lwenyawo kukuba lunzima, lusetyenziswe ixesha elide okanye kwiimeko ezimbi, kwaye amajoyina aphelile.
