The required accompanying drawing used is briefly described in embodiment or description of the prior art.In all of the figs, it is similar
Element or part are typically identified by similar reference.In accompanying drawing, each element or part might not be according to the ratios of reality
Draw.
Fig. 1 is a kind of exploded view of doublejointed Orthopaedic measuring ruler of the utility model；
Fig. 2-5 is respectively a kind of structural representation of the doublejointed Orthopaedic measuring ruler of the utility model under different conditions；
Fig. 6 is the structural representation of Section A-A in Fig. 2.
Embodiment
The embodiment of technical solutions of the utility model is described in detail below in conjunction with accompanying drawing.Following examples are only
For clearly illustrating the technical solution of the utility model, therefore example is only used as, and this practicality can not be limited with this
New protection domain.
As shown in figures 1 to 6, doublejointed Orthopaedic measuring ruler provided by the utility model, including：Connector 1, first is surveyed
The measuring scale 3 of gage 2 and second；One end of first measuring scale 2 and connector 1 is hinged, and is had on the first measuring scale 2 with it with connecting
Angle measuring calibration 11 centered on the pin joint of fitting 1, and have measure long scale 12 (for measuring length in its longitudinal direction
Degree)；The other end of second measuring scale 3 and connector 1 is hinged, and is had on the second measuring scale 3 with its pin joint with connector 1
Centered on angle measuring calibration 31, and have measure long scale 32 in its longitudinal direction；First measuring scale 2, the second measuring scale 3 divide
It is not equal to the width of human synovial with the distance between the pin joint of connector 1.Although human synovial according to test individual not
With and difference, but according to statistical method can determine different type (such as：Age, region etc.) joint of crowd is averaged
Length, and then according to the length of joint average length design connector 1.
First measuring scale 2, the second measuring scale 3 are respectively with being connected in doublejointed Orthopaedic measuring ruler provided by the utility model
The distance between pin joint of part 1 is equal to the width of human synovial, therefore is using measuring scale pair provided by the utility model
When human synovial measures, it is only necessary to ensure that two on connector 1 pin joints align i.e. with two end points of human synovial respectively
Can, the trouble for finding human synovial center accurately is avoided, improves the precision to joint measurment.
For the ease of the alignment in angle measuring calibration 31 and joint to be measured, the upper part of the second measuring scale 3 is used for the scale of measuring angle
Outwards extending has radial line 33.
In order to facilitate the overall length in measurement joint, long scale 32 and first is measured on the second measuring scale 3 in the utility model
Long scale 22 is measured on measuring scale 2 has continuity.It is so-called to refer to continuity：Long scale 32 is measured on second measuring scale 3 most
The difference of the maximum scale value of long scale 22 is measured in down scale value and the first measuring scale 2, equal to above-mentioned two scale value position
Actual physics distance.For specific distance, it is assumed that the maximum scale value on the first measuring scale 2 is 13, on the second measuring scale 3
Minimum scale value is 29, then the physical distance of the position of scale value 13 and the position of scale value 29 is equal to 16.Two measurements
Scale on chi has continuity, therefore the joint length value of the second measuring scale 3 measurement is the actual (tube) length angle value in joint, compared to
For scale on two measuring scales does not possess continuous ruler, the utility model avoids to add up to different rulers measurement size
Trouble, improve the efficiency measured to human synovial length.
After two measuring scales in the utility model are aligned with human synovial respectively, it is necessary to carry out artificial read and survey
Data are measured, and should be tried one's best during data are read and avoid two measuring scales from rotating again, therefore in the utility model
The place of being hinged of the first measuring scale 2 and connector 1 be provided with the first locking device (not shown), surveyed for locking first
Angle between gage 2 and connector 1.The place of being hinged of second measuring scale 3 and connector 1 is provided with the second locking device (figure
Not shown in), for the angle between the second measuring scale of locking 3 and connector 1.Specific locking device can use bolt and spiral shell
Female fit structure is realized, or other lockable mechanisms.
In order to improve adaptability of the utility model to different joint measurments, the first measuring scale 2 can be around it with being connected
The pin joint of part 1 is rotated by 360 °, and the second measuring scale 3 can be rotated by 360 ° around the pin joint of itself and connector 1.Thus, this practicality
The new state that at least may be at as shown in Figure 2-5.
In order to improve the overall crush resistance of the utility model, the first measuring scale 2, connector 1 in the utility model and the
Two measuring scales 3 are lucite material.
