Curative effect.
To achieve the above object, the utility model adopts the following technical scheme that.
A kind of Multi-functional knee joint intracavitary measuring scale of the utility model, including handle, the metal scale that is connected with the handle,
It is characterized in that：One end of the metal scale is to pass through with the integrally formed lengthening connecting rod of the metal scale, the metal scale
Connecting rod is lengthened with the handle to be connected；The metal scale is linearly or bending, is provided with the metal scale coarse
Bone file face and the scale face back to bone file face, the length of the metal scale is 5cm, width 5mm, thickness 2mm, the metal
The front end of chi is provided with sharp metal scale tip, and gradual constriction is at the 5mm of metal scale front end on described metal scale
Metal scale tip.
As a kind of preferred scheme of the present utility model, on described metal scale at the 3cm of metal scale front end to the left
Curved 30 degree are in bending.
As another preferred scheme of the present utility model, on described metal scale at the 3cm of metal scale front end to
Right curved 30 degree are in bending.
As another preferred scheme of the present utility model, on described metal scale at the 3cm of metal scale front end to
Upper curved 30 degree are in bending.
As another preferred scheme of the present utility model, on described metal scale at the 3cm of metal scale front end to
Under curved 30 degree be in bending.
Specifically, the angle of bend that metal scale described in the utility model is in, can be according to the tool in patient's knee joint cavity
Body actual conditions are designed.
The utility model beneficial effect.
1st, the utility model passes through above-mentioned linear and four kinds of curved geometrics metal scale, and the metal scale
The bone file face of upper setting and scale face, the complicated form being adapted in knee joint cavity, accurately measure fossa intercondylaris femoris, preceding intersection
The data of ligament femur, shin bone stop dissection trace and posterior cruciate ligament of knee femoral attachment dissection trace, instruct forward and backward intersection tough
Being accurately positioned when carrying out reconstruction operations with fracture, to ensure operative effect.
2nd, simultaneously, the bone file face of four kinds of curved geometrics of metal scale described in the utility model, can more easily grind
Bone face is filed, the spur of equating hyperplasia, facilitates operation technique.
3rd, metal scale front end described in the utility model is sharp metal scale tip, and geometry is bent by four kinds of metal scale
Shape, be advantageous to patient when carrying out due to cruciate ligament operative reconstruction, the pre- perforating at the femur dissection trace of ligamentaum cruciatum,
Drill bit slips at bone bed during so as to avoid directly using electric drill perforating, causes the anatomical position of ligament reconstructive inaccurate and shadow
The problem of ringing operative effect.
