Description
Technical field
The present invention relates to technical field of medical instruments, more particularly to a kind of shin bone adjustment seat.
Background technology
Knee joint is maximum in human body and is most complicated joint.Knee prosthesis is treatment degenerative arthritis, class
One of effective means of diseases of knee joint such as rheumatic arthritis, post-traumatic arthritis, flexion deformity, correlative study is also increasingly
Paid attention to.
In undergoing total knee prosthesis surface replacement operation, the displacement of femoral component, tibial component is related generally to, it is impaired to replace
Knee joint.Wherein, when carrying out osteotomy to shin bone, it is thus necessary to determine that accurate osteotomy amount, osteotomy site, back rake angle, varus angle and
Valgus angle.
Wherein, the determination of osteotomy amount is realized generally by shin bone bathometer, and shin bone bathometer needs when in use
It is connected with the finder of adjustment back rake angle, varus angle and valgus angle, and realizes the adjustment of shin bone bathometer height, it is existing
Adjustment mechanism is directly to be connected shin bone bathometer with orientation lever outside the proximal tibia marrow below finder, is glided by upper manually
The height to adjust shin bone bathometer and position are moved, the precision of adjustment is limited by the working experience of medical worker, and adjustment pair
Quasi velosity is slow, and precision is difficult to control, and is extended operating time, is unfavorable for the post-operative recovery of sufferer.
The content of the invention
The technical problems to be solved by the invention are：In order to overcome deficiency of the prior art, the present invention provides a kind of shin
Bone adjusts seat.
The present invention solves its technical problem technical scheme to be taken：A kind of shin bone adjusts seat, including mounting seat, pulls
Machine and adjustment are taken turns, and the mounting seat includes the column and base being vertically connected with, and the left and right sides of the column is arranged with two
