Chifukwa chiyani Radiopacity Imafunika M'makhola a TLIF: Nkhani Yakuyankha kwa Opaleshoni Yamsana

Mu njira ya TLIF kapena PLIF, dokotalayo akugwira ntchito kudzera munjira ya masentimita angapo m'lifupi, ndi mizu yotuluka ya mitsempha yomwe ikukhala pamphepete mwa njira yogwirira ntchito. Palibe mzere wolunjika kuti utsimikizire malo a khola - dokotalayo akuwerenga C-mkono, mobwereza bwereza, akukhulupirira kuti zomwe zikuwonetsa pa fluoroscopy monitor zikuwonetseratu bwino kumene khola limakhala logwirizana ndi danga la disc ndi zinthu za neural zozungulira.

Iyi ndi nthawi yomwe mtundu wa implants umasowa chakumbuyo kapena kukhala tcheru pazifukwa zonse zolakwika. Ngati zolembera za tantalum sizinalumikizidwe molakwika, zokhala pansi bwino, kapena zosagwirizana kuchokera ku khola kupita ku khola, dokotalayo amayenera kuyimitsa, kuwomberanso, kuwongoleranso, ndikungoyerekeza kuyika komwe kumayenera kutenga masekondi. Kuwombera kwina kulikonse kwa fluoro kumawonetsa ma radiation ambiri kwa gulu la OR komanso nthawi yambiri pansi pa opaleshoni ya wodwalayo. Ndipo ngati wogawa ndi amene wapereka khola limenelo, kugwa si bokosi lobwezeredwa la implants - ndi dotolo yemwe sangayimbirenso foni.

Zomwe zidawoneka pa Monitor

Ichi ndi chithunzi m'modzi mwa ochita opaleshoni athu omwe amatumizidwa mwachindunji kuchokera ku OR, mkati mwa njira, osafunsidwa.

Chithunzi cha intraoperative C-arm chotumizidwa ndi dokotala wa opaleshoni panthawi ya TLIF. Zambiri zozindikiritsa zasinthidwa kuti zinsinsi za odwala ndi opereka chithandizo.

Bwalo wobiriwira m'chifaniziro si athu - dokotala anajambula yekha asanatumize chithunzicho, kuti aloze ndendende zomwe ankafuna kuti tiwone: mawaya a tantalum pa khola, amatsimikiziridwa momveka bwino ndi thupi la vertebral, ndi ndondomeko yakuthwa, yosadziwika bwino pansi pa fluoroscopy.

Uthenga wake pambuyo pake unali waufupi: 'Nkhola yanu yam'chiuno ndi yodabwitsa.'

Ameneyo si kasitomala kukhala waulemu. Werengani motsutsana ndi chithunzi chomwe adatumiza, ndizowona zachipatala. Dokotala wapakatikati samajambula chithunzi cha polojekiti ndikuzungulira tsatanetsatane pokhapokha ngati tsatanetsataneyo ndi wofunikira pazomwe akuchita panthawiyo. Zomwe akunena ndikuti: cholembera jiometri chidawonetsa pomwe chiyenera, popanda kukayikira za momwe khola likuyendera, ndipo kuyikako kudadutsa popanda kuzungulira ndi kuwunika komwe khola lodziwika bwino limamukakamiza.

Ndilo mfundo yonse ya radiopacity yochitidwa molondola. Ilo silimadzilengeza lokha. Zimangotanthauza kuti dokotala wa opaleshoni samayenera kuganizira za implant - kokha za wodwalayo.

Chifukwa Chake Izi Ndizovuta Kupanga Kuposa Zomwe Zimawonekera

Ogawa omwe sanakhalepo nthawi pafakitale nthawi zina amaganiza kuti zolembera za tantalum ndizinthu zazing'ono - mawaya angapo amakanikizidwa mu PEEK cage , yachitika. M'machitidwe, iyi ndi imodzi mwamasitepe omwe amalephera kwambiri pakupanga khola, pazifukwa ziwiri zosiyana.

PEEK-to-Marker Interface

Tantalum ndi PEEK sizimalumikizana ndi mankhwala. Cholemberacho chiyenera kusungidwa mwamakina - kukanikizidwa mumsewu wopangidwa ndi makina olondola omwe amatha kupirira mokwanira kuti mipando yamawaya isungunuke bwino ndipo sichimasuntha mobwereza bwereza ndikuyika, kukhudza, ndi zaka zonyamula katundu pambuyo pake. Ngati tchanelocho chadulidwa mokulirapo pang'ono, cholemberacho chimatha kusuntha kapena kupendekeka panthawi yakugundana - zomwe ndi njira yolephera yomwe imawonekera ngati choyikapo kapena chojambula pawiri pa fluoroscopy, kukakamiza dokotalayo kuti awomberenso ndikuwunikanso.

Ili ndi vuto la makina a CNC amitundu isanu, osati yolumikizana ndi manja. Chizindikiro cha geometry chiyenera kudulidwa kuti chifanane ndi mawaya awiriwa ndi chilolezo chochepa, pa khola lililonse, pamlingo wopanga - osati pa zitsanzo zomwe fakitale imatumiza kuti iwunikenso.

Insertion Interface

Ogawa ena olephera amamva nthawi zambiri kuposa mawonekedwe a chikhomo: kulumikizana pakati pa khola ndi chida choyikirapo kumabwera momasuka. Ngati mawonekedwe a ulusi kapena keyed ali ndi kugwedezeka kwazing'ono, woyikirayo akhoza kubwerera kapena kusanja molakwika pansi pa kumenyedwa kwa mallet mobwerezabwereza komwe kumafunika kuti akhazikitse khola - lomwe ndi vuto lalikulu kwambiri mu khola la TLIF kusiyana ndi opaleshoni yotsegula, chifukwa dotoloyo ali ndi malo ochepa kwambiri kuti abwezeretse khola ndi dzanja ngati atapatukana ndi woyikirayo mosayembekezereka.

Kugwira kuti mawonekedwe a geometry osasinthasintha, khola pambuyo pa khola, batch pambuyo pa batch, ndi ntchito yachindunji ya kulekerera kwa CNC ndi kuyang'ana mozama - osati chinthu chomwe chingathe kukhazikitsidwa ndi kulongedza bwino kapena pepala la malangizo abwino.

Kodi Izi Zikutanthauza Chiyani Kwa Wogawa Akuwunika Opereka

Chifukwa chomwe tsatanetsatane wazinthu zopangira izi zimafunikira kwa wogawa - osati kwa dokotala wa opaleshoni - ndikuti mitundu yolepherayi siyimawonekera pachithunzi chamndandanda kapena papepala. Khola lokhala ndi cholembera chotayirira pang'ono kapena mawonekedwe olowera m'malire amawoneka ofanana ndi abwino mpaka atakhudzidwa ndi danga la disc ndi dotolo akuwonera C-mkono. Imeneyi ndi nthawi yoyipa kwambiri kuti mupeze kusiyana kwabwino, ndipo ndi nthawi yomwe imatsimikizira ngati akaunti yachipatala ikhala ndi inu kapena kusamukira kwa omwe akupikisana nawo.

Ichinso ndichifukwa chake 'kukumana ndi zojambulazo' sikufanana ndi 'kuchita mosadukiza.' Wothandizira atha kugunda ma dimensional spec pachitsanzo chotumizidwa kuti chiwunikidwe ndikukhalabe ndi kusiyana kwa batch-to-batch akangoyamba kupanga voliyumu yake. Njira yokhayo yodziwira kusiyanaku ndikufunsa zomwe zikuwongolera kusasinthika kumeneku - kuwunika kwa CMM mkati, kutsimikizira kulolerana kwa tchanelo, ndikuyesa ma torque oyika pazitsanzo pakupanga, osati kungoyang'ana koyamba.

Kwa ogulitsa kufananiza TLIF ndi PLIF makina a khola kwa ogulitsa, izi ndizofunikira kufunsa mwachindunji musanapange zowerengera: kulolerana kotani komwe kumachitikira pa cholembera, komanso kuchuluka kwa zitsanzo za QC pamawonekedwe a khola-to-inseter pa voliyumu yopanga - osati pamagawo owonetsera omwe amatumizidwa kuti awonedwe.

Zowona Zamalonda Pambuyo pa Kudalirika Kwachipatala

Palibe mwa izi ndi kupanga kwapadera kochitidwa kuti apindule ndi wogawa m'modzi. Kulekerera kwa malo okhala ndi choyikapo cholumikizira chofotokozedwa pamwambapa ndizomwe zimatuluka pamzere wopangira - njira yomweyo imayenda ngati dongosolo liri la mayeso amodzi kapena mtengo wathunthu wa mgwirizano wachipatala.

Kusasinthika kumeneku ndi komwe kumapangitsa kuti maoda otsika komanso okhazikika azigwira ntchito popanda kusinthanitsa kwabwino. Wogulitsa akuyesa gawo latsopano la msika, kapena kugwira ntchito ndi dotolo wochita maopaleshoni yemwe akufuna kuti pakhale njira yosiyana pang'ono kapena ma angle a lordotic kwa chiwerengero cha odwala m'derali, safunikira kudzipereka kuti agwire ntchito yonse kuti apeze kulondola komweku. Kukonzekera kwa khola la PLIF/TLIF ndi Mapulogalamu amtundu wa OEM/ODM amathandizidwa kuchokera ku seti imodzi ya MOQ - yomwe ili yofunika kwambiri pazomwe wogawa sanganene kuti ali ndi zinthu zokhazikika koma amafunikirabe implants zomwe zimagwira ntchito momwe dokotala wa opaleshoni pachithunzichi akufotokozera.

Kwa makola amtundu wanthawi zonse, mzere womwewo wopangira umakhala ndi 90% yowunikira pamtundu wamtundu wa msana, ndikuyitanitsa ma in-stock nthawi zambiri kutumiza mkati mwa masiku atatu abizinesi. Mfundo si yakuti kubweretsa mofulumira ndi kulolerana kolimba ndi malo ogulitsa osiyana - ndikuti zonsezi zimachokera ku chilango chofanana chopanga. Fakitale yomwe simatha kupirira kuchuluka kwa mphamvu nthawi zambiri satha kukhala ndi zida zofananira, ndipo mavuto awiriwa amawonekera limodzi.

Ngati mukuyang'ana wogulitsa msana ndipo mukufuna kuwona zolemba zenizeni zololera komanso zitsanzo za QC zomwe zili kumbuyo kwa zonena ngati izi, ndi chinthu chomveka kufunsa musanayike dongosolo loyamba - osati dokotala atatumiza chithunzi akufunsani chifukwa chake china chake sichinakhale bwino.
