Titanium yave sarudzo yekutanga yezvinoiswa pakuvhiya mubazi rezvekurapa nekuda kwehunhu hwayo hwakanaka uye kubatana kwayo nemuviri. Mumakore achangopfuura, kushandiswa kwetitanium muzvinoiswa pamafupa nemazino, pamwe nemidziyo yakasiyana-siyana yekurapa, kwakawedzera zvakanyanya. Kuwedzera uku kukurumbira kunogona kukonzerwa nehunhu hwayo hwakasiyana hwetitanium hwakadai sekusimba, kuramba ngura uye kuenderana nemuviri wemunhu. Muchinyorwa chino, tichaongorora zvikonzero nei titanium yave chinhu chinosarudzwa chezvinoiswa pamapurasitiki ekurapa, pamwe nezvinodiwa nemagiredhi chaiwo zvinoita kuti titanium ikwanise kushandiswa mumabasa akadaro.
Chimwe chezvikonzero zvikuru zvekushandiswa kwetitanium muma "medical implants" kwakawanda ndechekuti inoenderana ne "biocompatibility" yayo. Kana chinhu chikaonekwa se "biocompatibility", zvinoreva kuti inobvumirwa zvakanaka nemuviri uye haikonzeri "infectious immune reactions". "Biocompatibility" yeTitanium inokonzerwa nekukwanisa kwayo kugadzira "detective oxide layer" pamusoro payo kana yaiswa mu "oxygen". "Iyi oxide layer" inoita kuti titanium isashande uye isaparare nengura, zvichiita kuti isapindirane nemvura yemuviri kana matishu. Nekuda kweizvozvo, "titanium implants" hadzina mukana wekukonzera kuzvimba kana kurambwa, zvichiita kuti ive sarudzo yakachengeteka uye yakavimbika yekushandiswa mukurapa.
Pamusoro pekugona kushanda pamwe chete, titanium ine chiyero chakanaka chekusimba-kuhuremu, icho chakakosha kune zvinoiswa mumuviri zvinofanira kutsungirira kushushikana kwemuviri nekumanikidzwa kwemuviri. Ingave yezvinoiswa mumuviri, zvishandiso zvekugadzirisa mapfupa kana zvinoiswa mumazino, zvinhu zvinoshandiswa zvinofanira kunge zvakasimba zvakakwana kutsigira mashandiro emuviri pasina kurema zvakanyanya. Simba rakawanda reTitanium uye kurema kwakaderera zvinoita kuti ive chinhu chakakodzera kushandiswa kwakadaro, ichipa rutsigiro rwakakosha rwechimiro pasina kuwedzera huremu husina kufanira kana kushushikana mumuviri.
Pamusoro pezvo, titanium ine simba guru rekudzivirira ngura, izvo zvakakosha kune zvinoiswa mumuviri kwenguva yakareba. Nzvimbo yemuviri inoparadza zvakanyanya, uye mvura dzakasiyana-siyana dzemuviri uye ma electrolyte zvinogona kukonzera kuti zvinoiswa musimbi zviome nekufamba kwenguva. Titanium's natural oxide layer inoshanda sechidziviriro chengura, ichivimbisa kugadzikana kwenguva refu uye kuvimbika kwezvinoiswa mumuviri. Kudzivirira ngura uku kwakakosha zvikuru kune zvinoiswa mumidziyo zvinotakura mutoro, zvakaita sekutsiva chiuno nemabvi, uko zvinhu zvinofanira kutsungirira kushushikana kwemagetsi nguva dzose pasina kuora.
Masangano akati wandei epasi rose ane zvinodiwa zvakasimba zvematanho chaiwo uye mamakisi etitanium anoshandiswa muzvishandiso zvekurapa kuti ave nechokwadi chekuti zvinhu izvi zvakanaka uye zvakachengeteka. Sangano reAmerican Society for Testing and Materials (ASTM) rakagadzira mitemo yakaita seASTM F136 neASTM F67 inotsanangura kuumbwa kwemakemikari, hunhu hwemakanika, uye nzira dzekuyedza titanium yemhando yekurapa. Mitemo iyi inovimbisa kuti titanium inoshandiswa muzvishandiso inosangana nezvinodiwa kuti ienderane nemuviri, simba, uye kuramba ngura.
Pamusoro pezvo, International Organisation for Standardization (ISO) inotsanangura mhando dzetitanium, dzakadai seISO 5832-2, ISO 5832-3, uye ISO 5832-11, idzo dzinowanzoshandiswa mukugadzira ma "orthopedic implants" nemazino. Aya ma "ISO standards" anotsanangura zvinodiwa zve "titanium alloys" anoshandiswa mu "surgical implants", kusanganisira kuumbwa kwayo, hunhu hwe "mechanical properties", uye kuyedzwa kwe "biocompatibility". Ti6Al7Nb i "titanium alloy" inozivikanwa zvikuru ye "medical implants", ichibatanidza simba rakawanda, biocompatibility" uye "corrosion" yemhando dzakasiyana dze "implants".
Titanium yemishonga yekuisira mishonga inowanzo kuwanikwa muchimiro chematanda, waya, machira nemaplate. Mhando dzakasiyana idzi dzinogona kushandiswa kugadzira mhando dzakasiyana dzezvimisikidzo nemidziyo, kubva pazvikuro zvemapfupa nemaplate kusvika kumaburi emazino nemakeji emusana. Kuchinja-chinja kwetitanium mumhando dzakasiyana kunobvumira vagadziri kugadzirisa zvinhu zvinoenderana nemagadzirirwo nemashandisirwo chaiwo ezvimisikidzo, vachiona kuti chimisikidzo ichi chinosangana nezvinodiwa zvemakanika uye zvehupenyu.
Muchidimbu, kugona kwayo kuenderana nehupenyu, simba rayo uye kuramba kwayo ngura zvinoita kuti ive chinhu chinosarudzwa pakushandisa mishonga yekurapa. Mitemo chaiyo yakaita seASTM F136, ASTM F67, ISO 5832-2/3/11 uye Ti6Al7Nb inoita kuti titanium inoshandiswa mumishonga yekurapa inosangana nezvinodiwa zvemhando yepamusoro uye zvekuchengetedza. Nekukwanisa kwayo kutsungirira mamiriro emuviri uye kupa kugadzikana kwenguva refu, titanium inoramba ichiita basa rakakosha mukusimudzira tekinoroji yemishonga yekurapa uye kupa varwere mhinduro dzakavimbika uye dzinogara kwenguva refu dzezvinodiwa zvemapfupa nemazino.
Tinotungamirirwa neboka remainjiniya vane hunyanzvi uye nyanzvi dzeindasitiri vane ruzivo rwemakore anopfuura makumi maviri mukugadzira zvinhu zve titanium zvepamusoro. Tinonzwisisa kusiyana uye kukosha kwehupenyu uye pfungwa yedu yebhizinesi ndeyekushanda nevatengi vedu kuchengetedza hutano hwevanhu nebasa rakanaka, remhando yepamusoro uye rinokosha.
Tinokugamuchirai kuti mubatane nemazana evatengi veXinnuo vanofara kugadzira zvigadzirwa zveTitanium zvemhando yepamusoro kuti munhu ave nehupenyu hwakanaka uye hunofadza.
