Description
Technical field
The present invention relates to medical instrument artificial knee joint technical fields, and in particular to a kind of single condyle based on 3D printing is artificial
Knee joint prosthesis system.
Background technique
With the social development of China, the activity need of the people increasingly increases.Square dance, out on tours, body-building etc. cause
The amount of exercise of human body increased dramatically, and then the joint wear of the mankind is caused early stageization and multipleization trend occur.
Total knee replacement (TKA) is the therapeutic modality for solving most of knee joint sufferers at present, but which is for people
The damage of body is larger (bone removal amount is more, and complicated using performing the operation when needing to overhaul after many years), and in contrast single condyle knee closes
The damage of section displacement (UKA) is with regard to much smaller (bone removal amount is small, and later revision procedure is relatively easy).Fixation is current single condyle people
One of main problem existing for work knee prosthesis.
Single condyle artificial knee joint system includes lateral femoral condyle prosthesis, shin bone liner and tibial plateau prosthese.Lateral femoral condyle prosthesis with
Human femur under loading condyle is connected and fixed, and substitutes the condyle face of impaired lesion；Tibial plateau prosthese is connected and fixed with human tibia, and substitution is impaired
The tibial surface of lesion；Shin bone liner is located among lateral femoral condyle prosthesis and tibial plateau prosthese, bears human body pressure loading, meets fortune
Dynamic friction functional requirement.
The preprosthetic fixation of mesh is carried out by the way of bone cement+Tapered Column.It is solid which can provide early stage well
It is fixed, but fixed loosening can be led to due to the creep and abrasion of bone cement after being used for a long time, and then lead to solid failure, it carries out too early
Revision procedure.
Biological fixation is that principle is the porous structure that suitable dimension is produced by designing in prosthetic surface, passes through people after implantation
Self growth of bone, bone and prosthese form interlocking interface (attached drawing), are finally reached strong fixation.And due to skeleton
It is living body, can be with self growth, therefore abrasion will not be caused to loosen because of long-time service.
The key of biological fixation is that the porous structure design and manufacture at synosteosis interface.Turn-milling cutting traditional at present
Mode is unable to satisfy the manufacture of porous structure, and the manufacture of surface spraying also can only form rough interfaces on surface, is formed
One pseudo- porous interfacial layer, and the size dimension in hole is difficult to control.3D printing technique can manufacture porous structure, and ruler well
Very little controllable (size and Bone Ingrowth effect are closely related).
Notification number is that the Chinese patent of CN107280812A discloses a kind of artificial knee joint prosthesis, which is also to use
3D printing technique manufacture, but mainly for artificial full knee joint transposing (TKA), and mainly, tibia support uses 3D printing for the design
Porous structure is not the use of lateral femoral condyle prosthesis position, not can solve condyle of femur fixation problem.
Summary of the invention
In order to solve the above technical problems, it is an object of the invention to: a kind of artificial knee pass of single condyle based on 3D printing is provided
Prosthesis system is saved, solves to fix long term stability problem existing for single condyle artificial knee joint prosthesis at present.
The present invention is technical solution used by solving its technical problem are as follows:
Single condyle artificial knee joint prosthesis system based on 3D printing, including lateral femoral condyle prosthesis, shin bone liner and shin bone
Platform prosthese, the lateral femoral condyle prosthesis include the porous bulge-structure of condyle of femur of lateral femoral condyle prosthesis ontology and 3D printing, the stock
The porous bulge-structure of bone condyle is connected and fixed with human femur under loading condyle, and the tibial plateau prosthese includes tibial plateau prosthese ontology and 3D
The porous bulge-structure of the shin bone of printing, the porous bulge-structure of shin bone are connected and fixed with human tibia, and the shin bone pads position
Among lateral femoral condyle prosthesis and tibial plateau prosthese, shin bone pads corresponding lateral femoral condyle prosthesis and articular surface is arranged.
Lateral femoral condyle prosthesis of the present invention is connected and fixed with human femur under loading condyle, substitutes the condyle face of impaired lesion；Tibial plateau prosthese
It is connected and fixed with human tibia, substitutes the tibial surface of impaired lesion；Shin bone liner is located at lateral femoral condyle prosthesis and tibial plateau prosthese
Centre bears human body pressure loading, meets friction of motion functional requirement, the porous bulge-structure of the condyle of femur of 3D printing and 3D printing
Shin bone porous bulge-structure implantation after, self growth for passing through skeleton forms interlocking interface, Bu Huiyin with corresponding prosthese
Abrasion is caused to loosen for long-time service.The porous bulge-structure of shin bone of the porous bulge-structure of the condyle of femur of 3D printing and 3D printing
Aperture be set as 200um-600um, osteocyte tissue can be effectively facilitated to the porous interior growth of prosthetic surface, form interlocking fixed knot
Structure, simultaneously as being living cells, so because human motion causes fixed position tissue abrasion that can also pass through after fixed
Regeneration length is fixed again.Biological fixation is without using bone cement, and bone cement in use can make operation doctor
At olfactory stimulation, it is crushed after bone cement solidification once there is abrasion, does not have self-regeneration function.
Wherein, preferred embodiment are as follows:
The lateral femoral condyle prosthesis ontology and the porous bulge-structure of condyle of femur are the integral structure of 3D printing.
The lateral femoral condyle prosthesis ontology is fixedly connected with the porous bulge-structure of condyle of femur by screw or pin.
The porous bulge-structure of condyle of femur is integral type, and cross section is cross or linear type.
The porous bulge-structure of condyle of femur be it is split type, including the column that connect with lateral femoral condyle prosthesis ontology and/or stand
Plate.
The tibial plateau prosthese ontology and the porous bulge-structure of shin bone are the integral structure of 3D printing.
The tibial plateau prosthese ontology is fixedly connected with the porous bulge-structure of shin bone by screw or pin.
The porous bulge-structure of shin bone is integral type.
The porous bulge-structure of shin bone is split type.
The stable connection of above-mentioned integral structure, is fixed without screw or pin, and there is no the risks loosened, but is given birth to
Production process is complicated, and above-mentioned split type structure can be produced with sub-unit, and production is relatively easy, but screw or pin is needed to fix, long
Phase is using there may be the risks loosened.
It is slidably connected between the shin bone pads and the use of tibial plateau prosthese snaps connection or both contact surface, human body
Condyle of femur and shin bone pass through joint structure and ligament guarantee sports limiting.
Compared with prior art, the invention has the following advantages:
The present invention solves to fix long term stability problem existing for single condyle artificial knee joint prosthesis at present, lateral femoral condyle prosthesis with
Human femur under loading condyle is connected and fixed, and substitutes the condyle face of impaired lesion；Tibial plateau prosthese is connected and fixed with human tibia, and substitution is impaired
The tibial surface of lesion；Shin bone liner is located among lateral femoral condyle prosthesis and tibial plateau prosthese, bears human body pressure loading, meets fortune
After the porous bulge-structure implantation of the shin bone of dynamic friction functional requirement, the porous bulge-structure of the condyle of femur of 3D printing and 3D printing, lead to
Self growth for crossing skeleton forms interlocking interface with corresponding prosthese, and abrasion will not be caused to loosen because of long-time service.
