Description
Technical field
The invention belongs to Design for Medical Device technical field, especially relate to a kind of tibial prosthesis adapting to dissimilar tibia deformity and defect and set up system.
Background technology
At present, the Cranial defect of tibial side can be caused by many reasons, comprising: after the genu varum angulation deformity that arthritis causes, ischemic necrosis, wound, High Tibial Osteotomy and knee joint revision procedure.The Cranial defect of tibial side is divided into by defect: cavity defect and segmental defect; Be divided into by defect area: be less than 5mm, 5mm-10mm, more than 10mm three kinds.
In prior art, can solve by the following method the Cranial defect that tibial side exists:
1. Cement fixation: Cement fixation is applicable to the Cranial defect that the cavity defect degree of depth is less than 5mm, especially gerontal patient; But the relatively poor biomechanics characteristic of bone cement makes it be used in segmental and larger Cranial defect case, especially young patient;
2. bone grafting (autologous bone or allograph bone): bone grafting (autologous bone or allograph bone) is applicable to the cavity Cranial defect between 5-10mm, especially young patient; But autologous bone is drawn materials limited, and the remoldability of the safety of allograph bone, bone and integration ability poor, cause bone grafting failure;
3. metal correcting wedge and prolonging handle prosthese: metal correcting wedge and prolonging handle prosthese are applicable to the moderate Cranial defect between 5-10mm, the cavity Cranial defect being greater than 10mm and segmental defect, there is the situation that obvious bone amount reduces, or have the case of Progressive symmetric erythrokeratodermia bone loss also all applicable.
As can be seen here, for above-mentioned 3 kinds of clinical protocol, metal correcting wedge and prolonging handle prosthese is used to have obvious advantage.
Summary of the invention
The problem to be solved in the present invention is to provide and a kind ofly meets the customized demand of diverse bone types defect patient to prosthese, in conjunction with accurate, and the tibial prosthesis establishment system of the dissimilar tibia deformity of adaptation that healing effect is desirable and defect.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of tibial prosthesis adapting to dissimilar tibia deformity and defect sets up system, comprises the metal correcting wedge of tibial plateau prosthese, prolonging handle prosthese and assembly type; Described tibial plateau prosthese comprises platform body, fills cover and triangle wing plate, and described filling cover is the column structure of hollow, and this filling cover is arranged at below platform body; Described triangle wing plate is symmetricly set in fills cover both sides; Described metal correcting wedge matches with tibial plateau prosthese, is arranged at below platform body, and this side, metal correcting wedge outer and platform body outer match, and opposite side indent and triangle wing plate match; Described prolonging handle prosthese upper end stretch into tibial plateau prosthese filling cover in be connected and fixed.
Described metal wedge shape pad thickness is 5mm-20mm, and interval 1mm increases progressively.
Described prolonging handle prosthesis length is 40mm-160mm.
On described prolonging handle prosthese, radial direction is provided with relief groove.
Described prolonging handle prosthetic designs 0mm, 2.5mm, 5.0mm and 7.5mm tetra-kinds of offset distance sizes, select flexibly and combination in art, can correct the disease of various severe deformities.
Described triangle wing plate and platform are filled and are overlapped employing 360 ° of selectable Split type structures and design, be applicable to the proximal tibia of severe deformities anti-be rotated with fixed.
Owing to adopting technique scheme, the metal correcting wedge of (1) tibial plateau prosthese, assembly type and prolonging handle prosthese allow in art, be assembled into various prosthese, meet the customized demand of diverse bone types defect patient to prosthese; (2) thickness of metal correcting wedge is from 5mm-20mm, and interval 1mm increases progressively, and carries out filling process under realizing the prerequisite of the original bone amount of reservation as much as possible, and metal correcting wedge is maximized with the bone bed contact surface of carrying prosthese; Metal correcting wedge does not need to be incorporated on host bone simultaneously, the risk can not brought nonunion yet He subside; (3) metal correcting wedge is along with thickness difference, and width also changes thereupon; (4) wedge-shaped design of metal correcting wedge, exists and is press-fitted mechanism, do not need to use extra fixing also can with synestotic very accurate; (5) prolonging handle prosthesis length is from 40-160mm, and prosthese band relief groove designs, and assume responsibility for the body weight of human body about 30% while the stress in dispersion prosthese supported underneath face; (6) use tibial plateau prosthese and the metal correcting wedge of assembly type and the assembly of prolonging handle prosthese, be easy to the basic principle realizing knee prosthesis: correct lower limb are to the correct installation of line, prosthese, flexing gap and stretch the balance in gap, mobility that knee joint is enough.
The invention has the beneficial effects as follows: have and meet the customized demand of diverse bone types defect patient to prosthese, in conjunction with accurate, the advantage that healing effect is desirable.
