isibambo esisheshayo sokuhlanganisa

Amapuleti wephrofayili ephansi we-Ultra anemiphetho ehlanganisiwe kanye nephrofayili ebanzi yeplate ayinikezeli ngokushaya ngamandla. Kutholakala ngobude obenziwe ngezifiso obuningi.

Izinzuzo zezikulufu ze-titanium alloy:

1. Amandla aphezulu. Ubuningi be-titanium bungu-4.51g / cm³, buphakeme kunobo be-aluminium futhi bungaphansi kunobo bensimbi, ithusi ne-nickel, kepha amandla aphakeme kakhulu kunalawo ezinye izinsimbi. Isikulufu esenziwe nge-titanium alloy sikhanya futhi siqinile.
2. Ukumelana okuhle kokugqwala, i-titanium ne-titanium alloy kwimidiya eminingi kuzinzile kakhulu, izikulufo ze-titanium alloy zingasetshenziswa ezinhlobonhlobo zemvelo ezonakalisayo kalula.
3. Ukushisa okuhle kokushisa nokushisa okuphansi ukumelana.Izikulufu ze-Titanium alloy zingasebenza emazingeni okushisa aze afike ku-600 ° C futhi kususwe ama-250 ° C, futhi angagcina ukwakheka kwawo ngaphandle kokushintsha.
4. I-non-magnetic, non-toxic.I-Titanium iyinsimbi engeyona eyemagnetic futhi ngeke ifakwe kuzibuthe ezindaweni eziphakeme kakhulu zikazibuthe.Akuyona nje kuphela engeyona enobuthi, futhi inokuhambisana okuhle nomzimba womuntu.
Ukusebenza okuqinile kwe-anti-damping.Compared ngensimbi nethusi, i-titanium inesikhathi eside kakhulu sokuncishiswa kokudlidliza ngemuva kokudlidliza kwemishini nokudlidliza kagesi.Lokhu kusebenza kungasetshenziswa njengezimfoloko zokulungisa, izingxenye zokudlidliza kwama-grinders wezokwelapha we-ultrasonic kanye namafilimu wokudlidliza kwezikhulisa zomsindo eziphambili .

I-Thread design ye-torque yokuqala yokuqala ne-torque yokufaka ephansi. Ukukhethwa okubanzi kwamapuleti nemeshini, kufaka phakathi i-mastoid kanye ne-meshes yesikhashana, nezembozo zemigodi ye-burr yama-shunts.

Uma isikulufa siqina, kungcono?

Izikulufu zivame ukusetshenziselwa ukuhlinzeka ngamathambo ukucindezela indawo ephukile, ukulungisa ipuleti ethanjeni, nokulungisa ithambo kufreyimu yangaphakathi noma yangaphandle. Ingcindezi esetshenziselwa ukukhama isikulufu ethanjeni ilingana ne-torque esetshenziswe udokotela ohlinzayo.

Kodwa-ke, njengoba amandla e-torque anda, isikulufa sithola amandla amakhulu we-torque (Tmax), lapho amandla okubamba isikulufu ethanjeni ancipha futhi akhishwe ibanga elincane. Amandla okukhipha (POS) wukuqina ukusonta isikulufu siphume ethanjeni. Kuvame ukusetshenziswa njengepharamitha ukukala amandla okubamba isikulufa.Okwamanje, ubudlelwano phakathi kwetorque ephezulu namandla okukhipha akukaziwa.

Ngokwelashwa, odokotela abahlinzayo bamathambo bavame ukufaka isikulufa nge-Tmax engaba ngu-86%. Nokho, uCleek et al. ithole ukuthi ukufakwa kwesikulufa kwe-70% Tmax ku-tibia yezimvu kungafinyelela i-POS ephezulu, okukhombisa ukuthi amandla we-torsion ngokweqile angasetshenziswa emtholampilo, okuzonciphisa ukuzinza kokuqina.

Ucwaningo lwakamuva lwe-humerus kuma-cadavers wabantu nguTankard et al. kutholakale ukuthi i-POS ephezulu itholakale ku-50% Tmax Izizathu eziyinhloko zokwehluka kwemiphumela engenhla kungaba ukungahambisani kwezinhlobo ezisetshenzisiwe kanye namazinga ahlukile wokulinganisa.

Ngakho-ke, uKyle M. Rose et al. kusuka e-United States kukalwe ubudlelwano phakathi kwe-Tmax ne-POS ehlukene ngezikulufu ezifakwe kwi-tibia ye-cadavers yabantu, yabuye yahlaziya nobudlelwano phakathi kwe-Tmax ne-BMD nobukhulu bamathambo. Leli phepha lisanda kushicilelwa ku-Techniques in Orthopaedics. Imiphumela ikhombisa ukuthi i-POS enkulu futhi efanayo ingatholakala ku-70% no-90% Tmax ene-torque yesikulufu, ne-POS ye-90% Tmax screw torque inkulu kakhulu kunaleyo eyi-100% Tmax. Kwakungekho mehluko ku-BMD nobukhulu be-cortical phakathi kwamaqembu e-tibia, futhi kwakungekho ukuhlangana phakathi kwe-Tmax nalawa amabili angenhla. Ngakho-ke, ekwenziweni kwemitholampilo, udokotela ohlinzayo akufanele aqinise isikulufa ngamandla amakhulu we-torsion, kodwa nge-torque kancane ngaphansi kwe-Tmax. Yize i-70% ne-90% ye-Tmax ingafinyelela i-POS efanayo, kusekhona izinzuzo ezithile zokuqinisa isikulufu, kepha i-torque akumele yeqe ama-90%, ngaphandle kwalokho umphumela wokulungiswa uzothinteka.
