Body bottom portion is equipped with to match and the first inside protrusion with femur, and the shin bone guide plate includes shin bone guide plate ontology, the shin
Bone conduction plate ontology is equipped with to match and the second outside protrusion with shin bone, and the shin bone guide plate ontology bends downward extended
A pair presses pressure arm, and described by guide post is equipped on pressure arm, the guide post is equipped with guide hole.
Further, the femur guide plate and shin bone guide plate with a thickness of 0.4-0.6cm.
Further, the material of the femur guide plate and shin bone guide plate is biodegradable PLA.
Further, the femur guide plate ontology saves material, while binding face at font structure, rectangular-ambulatory-plane structure is returned
It is small, convenient for fitting like a glove for binding face, Anawgy accuracy is improved, convenient for playing heat transmission in the fabrication process.
Further, a height of 0.8-1.5cm of the guide post.
Further, the hole internal diameter of the guide hole is 0.3-0.5cm.
Further, described to be connected by pressure arm both ends by ribs.
Compared with prior art, the utility model has the following beneficial effects:
1. the utility model structure is simple, including femur guide plate and shin bone guide plate, can guarantee to knee joint femoral part and
The precision of pith cavity position is beaten in shin bone part, and human body is conveniently looked for found line, improves accuracy, and the measurement for reducing operation misses
Difference improves procedure efficiency, improves success rate, reduces risks；
Match the first inside protrusion 2. the femur guide plate body bottom portion of the utility model is equipped with femur, shin bone guide plate
Ontology, which is equipped with, can guarantee with the second outside protrusion that shin bone matches and is preferably bonded between femur and shin bone, increase essence
Accuracy.
3. the femur guide plate ontology of the utility model is extended a pair of by pressure arm at font structure, the bending of shin bone guide plate is returned
Convenient for playing heat transmission in the fabrication process, the caused fever discomfort when getting through pith cavity is avoided, the pain of patient is mitigated.
