Indlela Yokulinganisa I-TLIF kanye Ne-PLIF Cage Manufacturer e-China

Abasabalalisi abaqhathanisa abahlinzeki bekheji be-interbody bavame ukubheka izinga le-PEEK nentengo ngeyunithi ngayinye, bese becabanga ukuthi okunye kungashintshana. Akunjalo. Ikheji ye-TLIF noma i-PLIF iyidivayisi encane, eyinkimbinkimbi yejiyomethri okufanele ilungise izinto ezimbalwa ngesikhathi esisodwa - izinyawo, ubude, i-engeli ye-lordotic, iphethini yamazinyo e-endplate, ivolumu yewindi lokuxhunyelelwa, isixhumi esibonakalayo esifakiwe, nokubekwa komaka - futhi ukuthola noma iyiphi yazo engalungile ibonakala kokuthi NOMA, hhayi eshidini elicacisiwe.

Lona umhlahlandlela osebenzayo wokuhlola umakhi wekheji we-TLIF/PLIF ozinze eChina wadlula impahla kanye nokuqhathaniswa kwentengo abasabalalisi abaningi abaqala ngakho.

Ikheji Akuyona Nje I-PEEK Block

Kulula ukucabanga ngekheji le-interbody njengocezu olumise okwe-PEEK noma i-titanium enezimbobo ezithile ezisikwe kulo. Empeleni, isici ngasinye siyisinqumo sokuklama esinomphumela womtholampilo:

• I-Footprint - incane kakhulu futhi i-cage ibeka engcupheni ukwehla ku-endplate ye-vertebral; inkulu kakhulu futhi ngeke ihlale kahle emhubheni we-TLIF ngaphandle kokuhlehla ngokweqile

• Ubude — budinga ububanzi obanele ngokunyuka okuncane (ngokuvamile okuyizinyathelo ezingu-1mm) ukuze ubuyisele ubude bediski ngaphandle kokuphazamisa kakhulu ingxenye

• I-angle ye-Lordotic - amakheji ayisicaba awabuyisi ukuqondanisa kwe-sagittal; umkhiqizi onikeza inketho ye-engeli eyodwa kuphela kulo lonke uhla losayizi wabo akanikezi ngempela isistimu esebenzisekayo ye-anatomy eyahlukahlukene

• Amazinyo e-Endplate - iphethini yendawo egobile ephikisana nokufuduka kwekheji ngemva kokubekwa; ukuphakama kwezinyo ne-engeli kuthinta kokubili ukulungiswa kokuqala kanye nokukhipha kalula esimweni sokubuyekeza

• Iwindi lokuxhunyelelwa - indawo evulekile yezinto ezibonakalayo zethambo; incane kakhulu futhi indawo ehlangene isengozini, inkulu kakhulu futhi ubuqotho besakhiwo bekheji ngokwalo buyancipha.

• Isixhumi esibonakalayo sokufakwayo — indlela ikheji elivala ngayo ithuluzi lokufaka phakathi nokubekwa

• Omaka be-Radiopaque - ngokuvamile izikhonkwane ze-tantalum, ezisetshenziselwa ukuqinisekisa indawo yekheji kanye nokuma kwayo ngaphansi kwe-fluoroscopy njengoba i-PEEK ngokwayo inokukhanya.

Umkhiqizi ongakwazi ukukhuluma ngalezi zilinganiso ngokuqondile - hhayi nje 'sinikeza osayizi abaningi' - yilowo oqonda ngempela ukuthi bakhiqizani kunokuba nje aqhube uhlelo lwe-CNC ngokumelene nomdwebo onikezwe omunye umuntu.

I-PEEK vs. I-Titanium: Yini Ongayiqhathanisa Ngempela

Abasabalalisi bavame ukubuza ukuthi iyiphi into 'engcono.' Lowo akuwona umbuzo onempendulo eyodwa - kuya ngokuthi udokotela ohlinzayo uthanda kangakanani, izinga elithile elihlanganisiwe, kanye nezidingo zesithombe - ngakho-ke indlela ewusizo kakhulu ukuqhathanisa lokho umkhiqizi angakwazi ukukubhala mayelana nokusetshenziswa ngakunye kunokukhetha uhlangothi.

• Amadokhumenti abalulekile — ku-PEEK, lokhu kusho ukuqinisekisa i-PEEK yezinga lezokwelapha ngaphandle kokuqiniswa kwe-carbon fibre (i-carbon-fiber PEEK inamandla kodwa ifihla isithombe, esibalulekile ekuhloleni ukuhlangana kwangemuva kokuhlinzwa); nge-titanium, lokhu kusho izinga elithile lengxubevange nokuthi liqinile noma liphrintiwe nge-3D

• Izici zokuthwebula - I-PEEK inomsakazo, okuvumela odokotela abahlinzayo ukuthi bahlole inqubekelaphambili ye-fusion ekuthathweni kwezithombe zokulandelela ngaphandle kokuthi ikheji lisithe umbono; I-titanium iyi-radiopaque, abanye odokotela abahlinzayo abayikhethayo ukuze kuqinisekiswe indawo yekheji kodwa engenza ukuhlola ukukhula kwethambo ngekheji kube nzima.

• Idizayini engaphezulu - i-PEEK ebushelelezi inendawo ye-bioinert engakhuthazi ngokuqhubekayo ukukhula kwethambo; izindawo ze-titanium ezithungwe noma ezinezimbobo (okuhlanganisa nezakhiwo ze-trabecular eziphrintiwe nge-3D) ziklanyelwe ukukhuthaza ukuhlanganiswa kwe-osseo ngqo endaweni yokufakelwa.

• Izidingo zemishini — zombili izinto ezisetshenziswayo zidinga ukuhlangabezana namazinga okuhlola ukucindezelwa aguquguqukayo kumadivayisi ahlanganayo, kodwa amamajini edizayini eyamukelekayo ayahluka ngokuqina kwempahla.

Okufunayo kumkhiqizi imibhalo kuyo yomibili imigqa yezinto ezibonakalayo, hhayi indawo yokuthengisa yanoma iyiphi abangakhiqiza kakhulu ngayo.

Kungani I-Radiopaque Marker Placement Ibalulekile Empeleni

Njengoba amakheji e-PEEK engabonakali ngokucacile ku-fluoroscopy, izimpawu ze-tantalum ezishumekwe ekhejini ziwukuphela kwesiqinisekiso sikadokotela ohlinzayo sesikhathi sangempela sokuma kwekheji kanye nokuma phakathi kwenqubo ye-TLIF noma ye-PLIF - iphasishi elinombono oqondile olinganiselwe kakhulu. Uma labo bamaka behlala ngokungahambisani, noma befuduka ngesikhathi sokuthinteka, udokotela ohlinzayo ulahlekelwa ukuzethemba kulokho okubonisa i-C-arm.

Sihlanganise lokhu ngokuningiliziwe ku Kungani I-Radiopacity Ibalulekile Kumakheji e-TLIF , okuhlanganisa nesithombe sangempela sangaphakathi kokuhlinzwa udokotela ohlinzayo esithumele sibonisa ukubonwa komaka ngesikhathi sesimo sangempela. Kuhle ukufunda eduze kwalo mhlahlandlela, ngoba ubonisa ukuthi 'okwanele ngokwanele' ukubeka umaka kubukeka kanjani kumonitha ephilayo ye-fluoroscopy - hhayi nje kwisimangalo seshidi elithile.

Ukuhambisana Kwekheji kanye Nokufaka

Leli iphuzu lokuhluleka abasabalalisi abazwa ngalo izikhathi ezimbalwa kakhulu kunekhwalithi yezinto ezibonakalayo, kodwa kubangela izinkinga ezimaphakathi. I-interface phakathi kwekheji nesifaki sayo kufanele ibambe ngaphansi kokushayisana okuphindaphindiwe - ukushaya kwe-mallet kuhlalisa ikheji esikhaleni sediski - ngaphandle kokuxegiswa noma ukungahambi kahle.

Okufanele ukuhlole ngokukhethekile:

• Indlela yokukhiya efakiwe — intambo, ifakwe ukhiye, noma ilingana i-friction — nokuthi ibambe ngokuvikelekile yini ngokulandelana okugcwele

• Ukuqinisekiswa kokuma kwekheji — udokotela ohlinzayo angasho ukuthi ikheji libheke ngakuphi uma selilayishwe kusifaki, ikakhulukazi emhubheni lapho ukubonwa okuqondile kunqunyelwe khona

• Ukubekezelelwa komthelela - ingabe ukuxhumana kwekheji kubambelela ngaphansi kwamandla angempela okuthinta, noma kudinga ukuphathwa okuthambile okungajwayelekile okwehlisa udokotela ohlinzayo

• Ukungaguquguquki kwe-Dimensional - isixhumi esibonakalayo esifakiwe esifakwe ekhejini yokubekezelela efanayo ngemva kwekheji, inqwaba ngemva kwenqwaba, noma ilingana iyahluka ngokwanele kangangokuthi amanye amayunithi azizwa ekhululekile kunamanye.

• Ukufanisa insimbi — ingabe umkhiqizi unikeza isifaki njengengxenye yesistimu eqinisekisiwe nekheji, noma ingabe ithuluzi elivamile elilingana cishe

Ikheji elihlangabezana nayo yonke i-dimensional specs ephepheni kodwa elihlukanisayo nesifaki walo esithinta phakathi nendawo aliyona ukuphazamiseka okuncane - yicala elimile elinesikhala sediski esivele silungisiwe futhi isiguli singaphansi kwe-anesthesia.

Ibanga Lomkhiqizo le-TLIF ne-PLIF

Uma isixhumi esibonakalayo nesemishini sesiqinisekisiwe, umbuzo olandelayo ukuthi usayizi wangempela womenzi kanye nobubanzi bokumisa buhlanganisa yini okudingwa odokotela abahlinzayo:

• Imilobo yezinyawo eqondile uma iqhathaniswa negobile — amakheji agobile ajwayelekile ku-PLIF (ukubekwa kwamazwe amabili) kuyilapho i-TLIF ivamise ukusebenzisa umklamo omise okukabhanana noma omise okwezinso ofanele ukufakwa ohlangothini olulodwa.

• Ibanga lobude - ngokujwayelekile i-8-14mm ku-1mm increments yezinhlelo zokusebenza ze-lumbar, ezihlanganisa ububanzi bobude bediski okuhlangatshezwane nabo.

• Izinketho ze-engeli ye-Lordotic - okungenani inketho evamile kanye nenketho ye-hyperlordotic (imvamisa engu-0°, 6°, nangaphezulu kumasegimenti adinga ukulungiswa okwengeziwe kwe-sagittal)

• Ububanzi bezinyawo nobude - ukuhluka okwanele ukufanisa ubukhulu bomzimba we-vertebral ngaphandle kokuphoqelela ukuyekethisa kosayizi owodwa

• Ukuhambisana kwe-TLIF / PLIF / MIS — kungakhathaliseki ukuthi inkundla yekheji efanayo isebenza kuzo zonke izindlela ezivulekile nezingangeneleli kancane, noma ukuthi ukubekwa kwe-MIS kudinga idizayini yekheji ehluke ngokuphelele kanye nesistimu yokufaka

Ububanzi obuncane buphoqa ithimba lakho labadayisi ukuthi livumelane nodokotela abahlinzayo phakathi nengxoxo - ukubatshela ukuthi usayizi oseduze otholakalayo 'usondele ngokwanele' esikhundleni sokufanisa lokho icala elikufunayo.

Yimaphi Amadokhumenti kanye Nokuhlolwa Okufanele Abasabalalisi Bakucele?

Ngaphambi kokwenza i-inventory, cela:

• I-TS EN ISO 13485 isijobelelo sobubanzi - amakheji e-interbody fusion aqinisekisa ngokusobala ngaphakathi kwendawo eqinisekisiwe, hhayi ngaphansi kwesigaba somgogodla ojwayelekile.

• Izitifiketi ze-Material — Isitifiketi se-PEEK resin lot esiqinisekisa izinga lezokwelapha kanye nokungabikho kokuqiniswa kwe-carbon fiber (ngaphandle kwalapho i-carbon-fiber PEEK iyilokho oku-odwayo); Izitifiketi ze-titanium mill ngokumelene nezinga elifanele le-ASTM

• Amarekhodi okuhlola anobukhulu - Ukuqinisekiswa kwe-CMM ekugxilweni kwezinyawo, ubude, nokubekezelela umaka wesiteshi, hhayi nje ukuhlolwa kwesihloko sokuqala kodwa amasampula okukhiqiza aqhubekayo

• Imibiko yokuhlolwa kwemishini — ukuhlola okumile nokuguquguqukayo kwe-compression-shear nge-ASTM F2077 ngayinye noma okulingana namadivayisi e-interbody

• Ukulandeleka kanye namarekhodi eqoqo - ikheji elithile lingalandelelwa libuyele endaweni yalo yokukhiqiza kanye neqoqo lempahla eluhlaza ezinyangeni ngemuva kokuthunyelwa

Kwabasabalalisi ababuyekeza izinketho zekheji le-interbody fusion kubo bonke abahlinzeki, beqhathanisa le mibhalo nengokoqobo imininingwane yekheji ye-interbody fusion kanye Imigqa yomkhiqizo we-PEEK yekheji ihlangene iyindlela yokuhlola enokwethenjelwa kunokuqhathanisa izimangalo zokumaketha.

Inventory, MOQ, kanye nokusekelwa kwe-OEM

Amakheji e-Interbody aphethe i-matrix ecacisiwe ebanzi - izinyathelo eziningi, ukuphakama okuningi, ama-engeli amaningi we-lordotic - okusho ukuthi uhlu lwabasabalalisi kufanele luhlanganise izindawo eziningi ukuze kugwenywe ucingo lwasesibhedlela ngosayizi ongekho eshalofini. Amasistimu ekheji ekhathalogi ajwayelekile agcinwa ekufakweni okuphezulu kwempahla, nokuthunyelwa kwesitoko ngokuvamile phakathi nezinsuku zebhizinisi ezi-3, kunciphisa amathuba okuba igebe losayizi libe inkinga yokuhlela.

Usekelo lwe-OEM lwezinhlelo zekheji ngokuvamile luhlanganisa ukupakishwa nokwenza amalebula ngendlela oyifisayo, ukulungiselelwa kwekhathalogi ngemakethe, nokusekelwa kwemibhalo yokubhaliswa kwendawo — lokhu kuyashesha ukukusebenzisa. Ijiyomethri yekheji entsha yangempela noma isigxivizo sonyawo, ngokuphambene, sidinga ukuqinisekiswa kwedizayini nokuhlolwa komshini okubuyekeziwe ngaphambi kokuthi kuthunyelwe, futhi lowo mugqa wesikhathi kufanele ukhulunywe ngokucacile kunokuba ucwebezeliswe.

Uhlu Lokugcina Lokuhlolwa Komhlinzeki

Imibuzo yesitifiketi kanye nesiyalo sokukhiqiza lapha ilandela umqondo ofanayo ovezwe ekubukeni kwethu okubanzi I-China vs. Abakhiqizi bomgogodla base-US - yini ehlukanisa umhlinzeki wekheji onokwethenjelwa koyingozi ukulawulwa kwenqubo okubhaliwe, hhayi lapho imboni ihlala khona kumephu.
