Description
Technical field
Put down the present invention relates to medical instruments field, more particularly to a kind of total knee replacement DF and shin bone
Platform personalization osteotomy locating guide device and application method.
Background technology
One of primary goal of artificial knee replacement surgery be recover lower limb machinery the line of force, make hip joint pivot,
Knee joint midpoint and ankle-joint midpoint are located in an imaginary lower limb line of force on coronal-plane.Correct osteotomy is that postoperative acquisition is good
Basis of the good lower limb to line.
Osteotomy localization method clinically the most commonly used in total knee replacement is location technology in femur marrow at present
And shin bone marrow outside fix technology.It is in femur marrow to ensure in art that femur im rod accurately indicates the direction that DF dissects axis
One of operation key point of location technology.When being operated in art, expand the entry position of marrow, direction, depth and diameter etc. it is various because
Element can all influence and cause im rod position deviation, cause im rod accurately to indicate the direction of DF anatomical axis.
Therefore, the potential error risk of location technology is higher in femur marrow, and clinical research also demonstrate that this viewpoint.Shin bone marrow outside fix skill
In art, will generally embrace ankle device and be fixed on outside shank, em rod distal end will be indicated the body surface correspondence at ankle-joint midpoint by estimating
Position, near-end indicates intercondylar ridge center on tibial plateau articular surface to determine the shin bone line of force.Due to by estimating ankle-joint
Body surface profile, the precision at positioning ankle-joint midpoint is not high, and deviations can cause to produce obvious tibial plateau osteotomy deviation.
Therefore, there is the potential wind of osteotomy deviation using positioning osteotomy device in conventional femur marrow and shin bone marrow outside fix osteotomy device
Danger is higher, is easily caused postoperative lower limb machinery line of force deviation, influences operative effect.
Computer assisted navigation location technology and 3D printing personalization osteotomy guide plate location technology be to determine DF and
Two kinds of emerging technologies in proximal tibia osteotomy direction.Computer assisted navigation location technology be by the operation designing of individuation and
The data such as osteotomy and lower limb mechanical force Line To Line angle are quantified by real-time navigation, and are according to concrete condition determination in art
No existence information error, and carry out a kind of location technology of timely amendment.Computer assisted navigation location technology can be carried significantly
The osteotomy accuracy of replacement knee in arthroplasty high, but the technology can not extensive use because high to equipment requirement.3D printing individual character
Changing osteotomy guide plate location technology is rebuild according to preoperative lower limb CT or MRI image, by CAD, determines osteotomy angle
Degree and thickness, patient personalized osteotomy oriented module is built using 3D printing technique, and the personalization in art by the way that 3d is printed cuts
Bone oriented module fits matching with articular surface specific region so that it is determined that osteotomy direction in art.According to current most of clinical research
Report, 3D printing individuation osteotomy guide plate location technology compared with traditional osteotomy location technology, has no aobvious in osteotomy accuracy
Work advantage, but considerably increase medical treatment cost.
Therefore the personalized osteotomy positioning lead device of a set of high performance-price ratio of research and development, it is allowed to possess personalized accuracy higher
And clinical applicability, DF and tibial plateau bone-culting operation accuracy are improved, improve postoperative effect, it is that artificial knee is closed at present
Save one of important difficult point of replacement operation.
