Description
Technical field
The present invention relates to the field of medical instrument technology, more particularly to a kind of knee osteotomy angle measurement unit.
Background technique
Knee joint is the most complicated poly-axial motion joint of human dissection, and with the arrival of Chinese society aging, knee is closed
The patient for saving disease is more and more.Currently, to have become the various advanced stage complexity diseases of knee joint for the treatment of normal for total knee replacement
Clinical means, and achieve good effect.But with the extensive development of the operation, thus brought by problem
It is increasing.It is reported that the incidence of patellofemoral complications is 1.5%-12% after total knee arthroplasty, artificial knee joint is accounted for
The 50% of reason is overhauled, one of the most common reason that knee joint is overhauled is become.It is accurate that femoral prosthesis is rebuild in total knee arthroplasty
The rotation line of force, for improve operation acceptance rate and increase prosthese service life have great importance.It accurately determines
Femoral rotation becomes the key factor of successful surgery to line and correct osteotomy, placement prosthese.Bending in prosthetic replacement's operation
Bent gap balance it is postoperative for patient can normal life tool have very important significance, if the femoral prosthesis rotation line of force is bad,
Patient will lead to articular kinesiology, the exception of biomethanics when carrying out kneebend, this is to lead to the undesirable original of postoperative curative effect
One of because.
The knee joint joint complicated as one, other than the femoral head of relative motion, there are many more ligament and fleshes for side
Meat tissue needs the pressure applied in view of all collateral ligaments and musculature to femoral head when carrying out replacement knee in arthroplasty.
After needing to consider installation prosthese when osteotomy, the pressure between two opposite femorals head should be consistent, and otherwise will lead to
Prosthese unstable wear when in use, thus it is very crucial for the selection of osteotomy angle.There has been no specifically for osteotomy angle at present
Spend the surgical instrument measured.
Summary of the invention
The technical problems to be solved by the invention provide a kind of knee osteotomy aiming at the deficiency of above-mentioned background technique
Angle measurement unit can easily and efficiently measure femur osteotomy angle.
In order to solve the above technical problems, a kind of knee osteotomy angle measurement unit provided by the invention, including bottom plate and
The side of top plate, the bottom plate and top plate is hinged, and the top plate and knee joint femoral head corresponding position are provided with two groups of pressure sensings
Device, the knee osteotomy angle measurement unit further include having lifting mechanism, and the lifting mechanism is used for top plate along hinge joint
Rotation lifting, the pressure sensor are array pressure sensor.
In above-mentioned technical proposal kind, the lifting mechanism is lifting pincers, and end grafting is between the bottom panel and top panel；It is described
The fixing groove for the grafting of lifting mechanism end is offered in bottom plate and top plate.
The rackwork for accurate console lift angle degree is provided in above-mentioned technical proposal kind, the lifting mechanism.
The reading for reading bottom plate and top plate lifting angle [alpha] is fixedly installed in above-mentioned technical proposal kind, the lifting mechanism
Number mechanism.
In above-mentioned technical proposal kind, the pressure sensor is made of the multiple pressure inductors being distributed in matrix.
In above-mentioned technical proposal kind, the spacing distance of the pressure inductor is 0.4 ~ 8mm, preferably 2 ~ 5mm.
Compared with prior art, the beneficial effects of the present invention are: present invention employs two groups of pressure sensors can be straight
It connects when measuring knee articulation, the pressure parameter of opposite femoral head, passes through lifting top plate, when bilateral pressure is consistent, lifting
Angle is osteotomy angle, very convenient, fast, greatly ensure that the osteotomy success rate of replacement knee in arthroplasty；Meanwhile two
Group pressure sensor is array pressure sensor, can effectively avoid measurement error by array pressure sensor, provide
More accurate measurement data.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of apparatus of the present invention；
Fig. 2 is the structural schematic diagram of array pressure sensor of the present invention.
Specific embodiment
Specific embodiments of the present invention are described in further detail below in conjunction with attached drawing:
A kind of knee osteotomy angle measurement unit that the present invention designs, including bottom plate 1 and top plate 2, the bottom plate 1 and top plate 2
Side it is hinged, the top plate 2 is provided with two groups of pressure sensors 3, the knee osteotomy with knee joint femoral head corresponding position
Angle measurement unit further includes having lifting mechanism 4, and the lifting mechanism 4 is used to rotate top plate 2 along hinge joint and be lifted.
The lifting mechanism 4 can be lifting pincers, and end is plugged between bottom plate 1 and top plate 2.The bottom plate 1 and top
The fixing groove 6 for 4 end grafting of lifting mechanism is offered in plate 2 respectively.It is provided on the lifting mechanism 4 for accurately controlling
It is lifted the rackwork 5 of angle.The reading for reading bottom plate 1 and the lifting angle [alpha] of top plate 2 is further fixedly arranged on the lifting mechanism 4
Number mechanism.
When needing osteotomy, the present apparatus is inserted at the knee joint for needing osteotomy, femoral head is made to be located at pressure sensor 3
Place.Then movable knee joint, pressure sensor 3 can accurately measure the pressure parameter of bilateral femoral head at this time.Use lifting
Top plate 2 is lifted by mechanism 4, until the pressure parameter that pressure sensor 3 measures bilateral femoral head is consistent, passes through reading mechanism 5
It can be concluded that bottom plate 1 and top plate 2 are lifted angle [alpha] at this time, which is osteotomy angle.
Bottom plate 1 of the present invention and two groups of pressure sensors 3 of knee joint femoral head corresponding position setting are array pressure
Sensor.The pressure sensor 3 can be made of multiple pressure inductor 3a in matrix distribution.Between the pressure inductor
Gauge is from for 0.4 ~ 8mm, preferably 2 ~ 5mm.
The setting of the sensor is for more accurate measurement osteotomy angle, and the present apparatus is inserted into and need to cut by when use
At the knee joint of bone, it is located at femoral head at pressure sensor 3.Then movable knee joint, pressure sensor 3 can pass through at this time
The pressure inductor 3a of array distribution accurately measures the pressure parameter of knee joint bilateral when stretching, being bent, is movable, so as to
Enough obtain more accurate osteotomy angle data.Osteotomy is carried out according to above-mentioned data to be not only able to avoid leading to vacation because of angular deviation
The abrasion that body discontinuity generates, additionally it is possible to which service life and patient that prosthese is greatly improved use the comfort level of prosthese.
Core of the invention is using two group pattern formula pressure sensors, by above-mentioned array pressure sensor in osteotomy
When obtain osteotomy angle, therefore, protection scope of the present invention is not limited only to above-described embodiment, on the basis of the principle of the invention,
Any change or deformation using above-mentioned mechanism, all belongs to the scope of protection of the present invention.
