Description
Technical field
The invention belongs to Design for Medical Device technical field, more particularly, to a kind of CR types and PS type condyle of femur die trials and condyle
Between processor function integration structure.
Background technology
At present, according to the indication type of knee surgery, coincident with severity degree of condition, preoperative knee articulation degree situation, tough
The combined factors such as the balance of band are selected, and CR types or PS type knee-joint prosthesis may be selected.
CR types also known as posterior cruciate ligament of knee conservative knee-joint prosthesis, since it retains posterior cruciate ligament of knee, therefore save at the same time
The bone amount of fossa intercondylaris femoris, handles fossa intercondyloidea in art without special tool(s), is conducive to the revision procedure that may occur in the future；PS types
Also known as posterior cruciate ligament of knee not conservative knee-joint prosthesis, since it does not retain posterior cruciate ligament of knee, therefore need in art to condyle of femur
Between nest handled, formed boxlike lacuna, so as to accommodate tibial plateau pad prosthese column design, so as to fulfill and effectively control
The rear rolling of femur.
The femoral condylar components of CR types and PS type prostheses are due to its difference to fossa intercondyloidea processing mode, its lateral femoral condyle prosthesis
It is different.Installed in TKA operations before prosthese, it is necessary to by the pre-installation of die trial come determine the position of prosthese, size and
With degree situation, the die trial of CR types and PS type condyles of femur on existing market is entirely different and uncurrent.Its shortcoming is as follows：1.
If according to X-ray and movement of patient situation decision CR type prostheses during preoperative plan, but due to ligament balance, pass in performing the operation
It is PS type prostheses that the problems such as saving stability, which needs temporary changes, so that postoperative ankle stability is more preferable, patient's joint function recovery
More preferably, but due to preoperative without the condyle of femur die trial for preparing PS types in advance, therefore the difficulty realized is larger；2. if prepare at the same time
The condyle of femur die trial of two kinds of patterns of CR types or PS types, instrument weight is very heavy, not readily transportable, and the instrument Aseptic sterilisation of operating room closes
Case marker standard is also unable to reach：Because disinfection tool cumulative volume super large, it is overweight disinfect box pressure can be caused not permeate, so as to sterilize
Sterile requirement of performing the operation cannot be reached.
The content of the invention
The problem to be solved in the present invention is to provide a kind of actual conditions according to patient, can replace optimal operation plan at any time
And kit；Reduce number of tools and cost；Ensure prosthese installation site accuracy, reduce what each component in art was mutually matched
Link；Realize the CR types and PS type condyle of femur die trials and intercondylar processor function integration structure for effectively saving bone amount.
In order to solve the above technical problems, the technical solution adopted by the present invention is：A kind of CR types and PS type condyle of femur die trials and
Intercondylar processor function integration structure, including intercondylar milling cutter, condyle of femur die trial, intercondylar die trial, intercondylar processor and intercondylar bone
Knife, the intercondylar faying face of the condyle of femur die trial and the combination curved surface of intercondylar die trial are engaged；The intercondylar processor includes inserting
Enter end and connecting pin, the insertion end can be inserted into the intercondylar processor connecting hole in matched condyle of femur die trial, institute
Stating connecting pin can be connected with intercondylar milling cutter and intercondylar osteotome.
The intercondylar processor connecting pin is arranged to square attaching apertures.
The intercondylar milling cutter is Electric milling cutter.
The intercondylar osteotome is manual osteotome.
Due to the adoption of the above technical scheme, condyle of femur die trial and intercondylar die trial is connected, and realizes CR types and PS types
Whether condyle of femur die trial integrated design, retain posterior cruciate ligament of knee in no matter performing the operation, generally applicable；Condyle of femur die trial and intercondylar place
Being connected for reason device, realizes integrated design therebetween；And Electric milling cutter and hand can be combined by intercondylar processor
The integrated design of dynamic osteotome, can replace optimal operation plan and supporting instrument at any time according to the actual conditions of patient,
Reduce in TKA operations, 3/4 number of tools, effectively reduces instrument cost in a link, it is ensured that prosthese installation position
The accuracy put, reduces the link that each component is mutually matched in art, is realized while effectively saving bone amount by CR types and PS
The die trial of type condyle of femur and intercondylar processor function integration.
The beneficial effects of the invention are as follows：With replacing optimal operation plan and kit at any time；Reduce number of tools and
Cost；Ensure prosthese installation site accuracy, reduce the link that each component is mutually matched in art；Realize and effectively save the excellent of bone amount
Point.
