Stryker Xigwitsirisi xa le ndzhaku lexi andlariweke

Nkatsakanyo wa Swikumiwa

Stryker Expandable Lumbar Cage yi hlanganisa xivumbeko xa michini lexi ndlandlamuxiwaka xa vutumbuluxi na thekinoloji ya le henhla ya Tritanium 3D‐printed. Xitirhisiwa lexi xi vuyisela ku tlakuka ka disc na segmental lordosis hiku tirhisa in‐situ expansion, kasi xivumbeko xa xona xa biomimetic porous xi endleriwe ku tlakusa ku kula ka marhambu endzeni ka marhambu xikan’we na biological fixation. Yi kombisiwa eka ku hlanganisiwa ka le ndzhaku ka le ndzhaku ka le xikarhi ka miri (PLIF ) na ku hlanganisiwa ka miri exikarhi ka miri ya le ndzhaku ka transforaminal ( .TLIF ).

Swikombiso swa Tliliniki

• Ku lunghisa vuvabyi bya pseudoarthrosis

Tilevhele leti kongomisiweke: L1 – S1 (levhele yin’we kumbe yo tala)
Maendlelo ya vuhandzuri: PLIF / TLIF

Swihlawulekisi Swa Nkoka

Dizayini leyi Andzisiwaka

• Ku ndlandlamuxiwa ka in‐situ – ku vuyisela ku tlakuka ka intervertebral na lordosis hiku tirhisa ku andzisiwa loku lawuriwaka

• Ku leha ka le hansi ka ku nghenisiwa – profile yosungula leyintsongo yi olovisa ku vekiwa lokunga ngheneriki ngopfu

• Vulawuri byo tiyimela – ku ndlandlamuxiwa ka le mahlweni kumbe endzhaku loku hlawuriwaka ku lulamisa lordosis

Thekinoloji yo Gandlisa ya 3D ya Tritanium

• Thekinoloji ya AMagineTM ya vulawuri – vumaki bya swiengeteri eka architecture ya porous leyi kongomeke

• Biomimetic porosity – vukulu bya pore lebyi nga tshamisekangiki na xivumbeko lexi tekelelaka marhambu ya cancellous

• Ti pores leti hlanganisiweke hiku hetiseka – through‐pores kusuka eka endplate kuya eka endplate

• Vuswikoti byo khoma mati – ku khoma mati yo antswa loko ku pimanyisiwa na titanium ya ndhavuko

Swihlawulekisi swa Dizayini ya Xikhege

• Mafasitere lamakulu yale matlhelo – ya olovisa ku paka ka marhambu ya graft xikan’we naku kamberiwa ka radiographic fusion

• Meno yo khoma ya bi‐directional – ti solid‐tip serrations ta multi‐directional anti‐migration

• Nhlawulo wa profile leyi govekeke – Tritanium TL curved cage ya ku nghenisiwa loku kongomisiweke

Swihlawulekisi swa Vukulu

• Tisayizi to tala ta footprint ti kumeka

• Nhlayo ya ku leha: 8 – 14 mm

• Ti angles ta Lordotic: 0° / 6° / 12° (ku katsa na 12° ya xihlawuhlawu xa hyper‐lordotic)

Ku pimanisa – Stryker Expandable Cage vs. Xigwitsirisi xa Ndhavuko xa Static

Vutivi bya tliliniki: Thekinoloji ya Tritanium eka Stryker Expandable Lumbar Cage yi tirhisa ku kandziyisa ka 3D ku tumbuluxa xivumbeko xa cancellous bone‐like porous lexi endleriweke ku tlakusa ku kula ka marhambu endzeni ka marhambu na ku khomiwa ka biological. Data ya tliliniki yikombisa ti fusion rates ta 91‐96% na ti Tritanium cages.

Ku kuma swo tala milandzu ya vuhandzuri bya xitirhisiwa lexi, hi kombela tihlanganise na hina.

Ha Yini U Hlawula CZMEDITECH tanihi Muphakeri wa Wena wa Stryker Expandable Lumbar Cage?

• Minimally invasive friendly – ​​ku tlakuka ka le hansi kosungula swiendla leswaku ku nghenisiwa ka incision leyintsongo

• Swi hlohletela fusion – Tritanium porous structure leyi endleriweke ku kula ka marhambu endzeni ka marhambu

• Ku fambisana ka radiographic – switirhisiwa swa titanium + mafasitere lamakulu ya ku kamberiwa ka fusion endzhaku ka vuhandzuri

• Swihlawulekisi swotala – ti straight/curved profiles, vukulu byohambana hambana eka anatomy yohambana hambana

• Swi tiyisisiwile hi tliliniki – nseketelo wa datha ya mpimo wa ku hlanganisiwa (91‐96%) .

Swivutiso Leswi Vutisiwaka Nkarhi Na Nkarhi (FAQ) .

1. Hi kwihi ku hambana lokukulu exikarhi ka xisaka lexi andlariwaka na xisaka xa ndhavuko lexi nga cinciki?

Cage leyi andlariwaka yi nghenisiwa eka vukulu byale hansi byosungula kutani yi andlariwa kuya eka ku tlakuka loku lavekaka endzeni ka ndzhawu ya disc. Dizayini leyi yi hunguta ku tlhelela endzhaku ka timintsu ta misiha naswona yi pfumelela ku vuyiseriwa loku kongomeke swinene ka ku leha ka disc na segmental lordosis. Ti static cages ta ndhavuko ti lava impaction eka ku tlakuka ko hetelela, leswinga engetelaka ku tika ka ku nghenisa.

2. Xana thekinoloji ya Tritanium i yini?

Tritanium i xitirhisiwa xa Stryker xa titanium xa high‐porosity lexi endliweke hi ku tirhisa thekinoloji yo kandziyisa ya AMagineTM 3D. Yi na ti pores letinga tshamisekangiki, leti hlanganisiweke leti endleriweke ku tekelela morphology ya cancellous bone xikan’we naku hlohletela bone ingrowth xikan’we na biological fixation.

3. Xana xisaka lexi nga ndlandlamuxiwaka xi na khombo ro khuluka?

Tidyondzo ta biomechanical ti kombisa leswaku vuenti bya subsidence byi fambelanisiwa swinene na ku tsindziyela ka marhambu. Ehansi ka torque ya expansion leyi fanaka, density ya marhambu yale hansi (xikombiso, 5 PCF) yikombisa ku hunguteka ka kwalomu ka 2.3 mm, kasi density yale henhla ya marhambu (20 PCF) yikombisa kwalomu ka 1.1 mm. Madokodela ya vuhandzuri ya fanele ku hlawula vukulu lebyi faneleke hi ku ya hi khwalithi ya marhambu naswona ya endla vuxiyaxiya.

4. Xana fusion rate ya cage leyi i yini?

Data ya tliliniki yikombisa ti fusion rates ta 91‐96% na ti Tritanium cages eka 12 wa tinhweti. Single‐cage fusion rate i 91%, naswona dual‐cage fusion rate i 96%.

6. Hi tihi tindlela ta sayizi leti nga kona?

Tisayizi to tala ta footprint ta kumeka, na ku leha ka 8‐14 mm na swihlawulekisi swa lordotic angle swa 0°, 6°, na 12° (ku katsa na 12° hyper‐lordotic option).

7. Xana xisaka xi swi sivela njhani ku rhurha?

Cage yina ti precision‐angled serrations letingana ti tips leti tiyeke, leti endleriweke ku nyika bi‐directional anti‐migration capacity xikan’we naku kurisa ndzhawu ya endplate contact surface.

8. Hi wahi maendlelo ya vuhandzuri lama kombisiweke eka xisaka lexi?

Ngopfu ngopfu yi kombisiwa eka ku hlanganisiwa ka miri wa le ndzhaku ka le ndzhaku (PLIF) na ku hlanganisiwa ka miri wa le ndzhaku ka le ndzhaku ka le ndzhaku (TLIF).

9. Xana ndzi nga kuma kwihi buku ya thekiniki ya vuhandzuri kumbe vuxokoxoko bya nxavo?

Hi kombela u tihlanganisa na muxavisi wa Stryker wa le ndhawini ya ka n’wina kumbe u endzela webusayiti ya ximfumo. Swiletelo leswi heleleke swa tindlela ta vuhandzuri, tikhathalogu ni swikombo swa kumeka loko swi komberiwa.
