Description
Technical field
The present invention relates to technical field of medical instruments, more particularly to a kind of knee joint gap measuring device.
Background technology
As shown in figure 1, needing to ensure the equal apart from d1 and d2 of both sides between femur and shin bone when knee surgery is done
Or between both gaps no more than predictive error, if the too big needs of difference will be cut apart from small one end.In reality
Border is to judge the distance of d1 and d2 by rule of thumb by doctor during performing an operation, i.e., seen with eyes, so to the technology of doctor
It is required that it is higher, nor can guarantee that d1 and d2 are equal.
The content of the invention
The present invention proposes a kind of knee joint gap measuring device, and solving cannot accurately measure femur and shin in the prior art
The problem of both sides spacing between bone.
A kind of knee joint gap measuring device of the invention, including：Support base and respectively positioned at support base two ends top
With four measuring scales of bottom, four measuring scales are each perpendicular to the upper and lower part surface of support base.
Wherein, described measuring scale one end is located in the support base, and the other end stretches out top or the lower surface of support base.
Wherein, also include：The governor motion that measuring scale stretches out the support base length surface is connected and adjusted with measuring scale.
Wherein, the governor motion includes：Driver plate, gear shaft and chute, the chute are located in support base, the driver plate
Outside the wall of support base side, the measuring scale is slidably located in chute, and one end is worn by the through hole set on support base
Go out support base, the gear shaft is located in the support base, and is connected with driver plate through the damping bearing being arranged on the side wall
Connect, the measuring scale is provided with tooth bar, and with the ratcheting connection of the gear shaft.
Wherein, for two relative measuring scales positioned at the support base upper and lower part, its corresponding two chute
Between be provided with postive stop baffle.
Wherein, the measuring scale is provided with limited block.
Knee joint gap measuring device of the invention, measuring scale is equipped with the top and the bottom at support base two ends, by the device
It is placed between kneed femur and muscles and bones, the spacing of both sides between femur and shin bone can be accurately measured by measuring scale.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
The accompanying drawing to be used needed for having technology description is briefly described, it should be apparent that, drawings in the following description are only this
Some embodiments of invention, for those of ordinary skill in the art, without having to pay creative labor, may be used also
Other accompanying drawings are obtained with according to these accompanying drawings.
Fig. 1 is knee joint schematic diagram；
Fig. 2 is a kind of knee joint gap measuring device structural representation of the invention；
Fig. 3 is the side view of Fig. 2；
Fig. 4 is the cut-away view of Fig. 2 dotted box portions.
Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
A kind of knee joint gap measuring device of the present embodiment as shown in figs. 2 to 4, including：Support base 1 and respectively be located at branch
Four measuring scales 2 of the upper and lower part at support seat 1 two ends, four measuring scales 2 are each perpendicular to the upper and lower part table of support base 1
Face.
In the present embodiment, measuring scale 2 is equipped with the top and the bottom at the two ends of support base 1, the device is placed on kneed stock
Between bone and muscles and bones, the spacing of both sides between femur and shin bone can be accurately measured by measuring scale 2.Specifically, support base 1
Height by the scale reading and the height summation of support base 1 of upper and lower two measuring scales, it is known that can obtain the distance of d1 and d2.
In the present embodiment, the one end of measuring scale 2 is located in support base 1, and the other end stretches out top or the bottom table of support base 1
Face, i.e. support base 1 are provided with the through hole for passing through measuring scale 2 so that measuring scale 2 can be fixed more securely.
The knee joint gap measuring device of the present embodiment also includes：Measuring scale 2 is connected and adjusted with measuring scale 2 stretches out support
The governor motion of 1 length surface of seat, the length that the surface portion of support base 1 can be stretched out to measuring scale 2 is finely adjusted, to adapt to survey
Measure the distance of both sides between different size of kneed femur and shin bone.
Specifically, as shown in figure 4, governor motion includes：Driver plate 3, gear shaft 4 and chute 5, chute 5 are located at support base 1
Interior, driver plate 3 is located at outside the side wall of support base 1, and measuring scale 2 is slidably located in chute 5, and one end on support base 1 by setting
Through hole pass support base 1, gear shaft 4 is located in support base 1, and (is not shown in figure through the damping bearing being arranged on the wall of side
Go out) be connected with driver plate 3, measuring scale 2 is provided with tooth bar (side contacted with gear shaft 4), and with the ratcheting connection of gear shaft 4.It is logical
Cross and stir driver plate 3 and rotated with movable gear shaft 4, gear shaft 4 drives measuring scale 2 to be moved up and down along chute 5.Due to using damping bearing
Even if measuring scale 2 reaches eminence, also will not be because of Gravitational sliding.
For two relative measuring scales 2 positioned at the upper and lower part of support base 1, set between its corresponding two chute 5
Limited location baffle plate 51, postive stop baffle 51 avoids measuring scale 2 and excessively moves down or upper shifting, interferes.
Measuring scale 3 is provided with limited block 21, and in upper shifting or when moving down to a certain extent, limited block 21 can block through hole cannot
It is further continued for moving or moving down, it is to avoid excessively movement makes tooth bar depart from gear shaft 4 to measuring scale 2 up or down.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all it is of the invention spirit and
Within principle, any modification, equivalent substitution and improvements made etc. should be included within the scope of the present invention.
