TKA Prosthesis- LDK X4 Thawj Tag Nrho Lub hauv caug Arthroplasty
1.
Lub anterior condyle ntawm lub femoral prosthesis yog muab nrog txo qhov dav thiab tuab kom txo cov anterior condyloid siab thiab quadriceps nro.Tib sagittal geometry thiab tus curvature du cia lub patella tsis ua rau kom lub zog ntawm lub quadriceps femoris thaum lub hauv caug stretches thiab flexes.Ua ke nrog qhov sib sib zog nqus patellar trochlear zawj, nws tuaj yeem ua kom ntseeg tau tias patella yog qhov ruaj khov thiab hauv qhov zawj txawm nyob rau hauv siab flexion yam tsis muaj dislocation, thiab ruaj khov kev sib cuag ntawm patella thiab femoral prosthesis yog khaws cia txhua lub sijhawm.
2.
Lub femoral prosthesis yog tsim los nrog ib tug me ntsis nkhaus coronal dav hlau los ua kom cov cheeb tsam sib cuag kom txo tau lub siab ncov ntawm polyethylene insert.Lub taw tes-rau-taw tes ntug bearing raug tshem tawm thaum lub sij hawm varus-valgus rotation ntawm lub hauv caug, yog li ntawd tibiofemoral sib koom ib txwm tuav lub ntsej muag sib cuag.
3.
Lub anterior patellar notch ntawm polyethylene insert yuav txo tau lub siab ntxiv thiab nro ntawm lub quadriceps femoris thaum lub sij hawm siab flexion.
4.
Lub posterior condylar curvature yog nce.Tibiofemoral articular nto tseem nyob rau saum npoo es tsis yog taw tes sib cuag thaum flexion mus txog 135 degrees.
5.
Qhib intercondylar fossa tsim: Lub intercondylar osteotomy txo qis, thiab cov pob txha tau khaws cia rau qhov loj tshaj plaws rau tus neeg mob.
6.
Optimized cam-post qauv: Lub cam tseem khaws cia ntawm lub hauv paus ntawm kem thaum lub hauv caug yog nyob rau hauv siab flexion, tiv thaiv qhov tshwm sim ntawm ncauj tsev menyuam dislocation thaum lub sij hawm siab flexion rau ib tug tsawg npaum li cas.
7.
Ib qho tshwj xeeb ntxig locking mechanism yog muab.Qhov thib ob fixation nrog hlau anchors yuav tshem tawm cov fretting hnav ntawm ob.
8.
Cov qauv tri-tis tiv thaiv kev sib hloov thiab tsis txhob muaj kev ntxhov siab.
