IyoJDS hudyu chiridzwainomiririra kufambira mberi kukuru mukuvhiyiwa kwemapfupa, kunyanya munyaya yekuvhiyiwa kwekutsiva chiuno. Zvishandiso izvi zvakagadzirirwa kuvandudza kururama uye kushanda zvakanaka kwekuvhiyiwa kwekutsiva chiuno, uye zvinogadziriswa zvinoenderana nezvinodiwa nevanachiremba nevarwere zvinogara zvichichinja.
JDSchiridzwa chejoini rechiunoine dhizaini itsva inoita kuti kuvhiyiwa kuve nyore. Chishandiso ichi chinosanganisira zvishandiso zvakakwana zvekubatsira mukuisa shaft yejoini rechiuno nemazvo, zvichiita kuti zvive nyore uye zvigadzikane. Izvi zvakakosha kuti ma implants echiuno abudirire kwenguva refu, sezvo kuiswa kwakakodzera kunogona kuderedza zvakanyanya njodzi yematambudziko uye kuvandudza fungidziro yemurwere.
Seti yeHudyuMashandisirwo uye Mashandisirwo Ekuvhiya Kwemapfupa
Imwe yenzira huru dzekushandisaZviridzwa zveJDS zvehudyui "total hip arthroplasty" (THA), inova kuvhiyiwa kwakajairika kune varwere vane arthritis yechiuno kana kuti kutyoka kwemapfupa. Chishandiso ichi chinobatsira vanachiremba vanovhiya kugadzirira zvakanaka socket yechiuno nefemur kuti vave nechokwadi chekuti chiuno chakagadzirwa zvakanaka uye chakasimba. Dhizaini yayo ye ergonomic inobvumira kuchinjika kukuru, nokudaro ichideredza njodzi yematambudziko ekuvhiyiwa.
Musimboti weChiridzwa chehudyundiyo femoral shaft pachayo, iyo inowanzogadzirwa nezvinhu zvine simba guru zvakaita setitanium kana cobalt chromium alloy. Takasarudza zvinhu izvi nekuda kwekubatana kwazvo uye kugara kwenguva refu kwekushandiswa kwenguva refu mumuviri wemunhu. Femoral shaft inonamatira zvakanyanya kufemur, ichipa hwaro hwakasimba hwejoinhi rechiuno rekugadzira.
Chimwe chinhu chakakosha ireamer, iyo inoshandiswa kugadzirira femoral tube ye femoral shaft. Reamer inoita kuti femoral tube ive nehukuru hwakakodzera uye chimiro chakakodzera, nokudaro ichivimbisa kuti femoral shaft yakachengeteka. Danho iri rakakosha pakuderedza njodzi yematambudziko uye kuona kuti implant inogara kwenguva refu.
Pamusoro pezvo, midziyo iyi inogona kusanganisira zvinhu zvakasiyana-siyana zvekuedza zvinobvumira vanachiremba kuti vaedze saizi dzakasiyana uye magadzirirwo vasati vaisa jira rekupedzisira. Maitiro ekupfeka jira rekuyedza akakosha pakubatsira murwere kushanda pamwe chete uye kushanda zvakanaka.
Muchidimbu,chiridzwa chejoini rechiunoine zvikamu zvakakosha zvakati wandei, zvinosanganisira femoral stem, reamer, calibration guide, uye test. Chikamu chimwe nechimwe chakakosha pakuona kuti kuvhiyiwa kwechiuno kunofambira mberi, zvichivandudza fungidziro yemurwere uye kusimudzira hupenyu hwevarwere vane zvirwere zvechiuno.
