Specific embodiment
As described in the background art, the success rate of image joint needs to be further increased in the prior art.
Inventors have found that the movement of one side patient or making ruler can all lead to the failure for influencing to splice, on the other hand,
The magnifying power of limbs image and making ruler image is different or deformation of image, cause the length and shape of limbs image untrue and
Splicing is caused to fail.
Inventor further study show that, the magnifying power of limbs image and making ruler image is different or the master of deformation of image
Want the reason is that as making ruler and limbs of patient height it is inconsistent caused by.Since X-ray is a point light source, the X of sending is penetrated
It after line is irradiated irradiated body in coniform radiation, is imaged on detecting devices thereunder, since X-ray is in coniform
Radiation, imaging can have certain magnifying power.Have centainly since the bone of patient has between certain altitude, with camera stand
Difference in height, the difference in height between lead ruler and bone makes the imaging of lead ruler and limbs of patient have different magnifying powers, to image
It causes to deform, the length of limbs of patient image is untrue, so that image joint be caused to fail.
At present clinically, the splicing photography of clinostatism overall length is carried out, is still directly to be placed in making ruler on camera stand, without specially
With equipment with fixed and adjustment lead ruler height.
Technical solution of the present invention provides a kind of overall length imaging marker ruler device, the overall length imaging marker ruler device packet
Include height adjusting member, it may be convenient to which the height of aignment mark ruler can adjust making ruler for different patients accordingly
Height, keep the bone site holding of making ruler and patient horizontal, to reduce magnifying power and light cone effect caused by image
Deformation, improves the success rate of image joint.
To make the above purposes, features and advantages of the invention more obvious and understandable, with reference to the accompanying drawing to the present invention
Specific embodiment be described in detail.
First embodiment
Referring to FIG. 1, for the structural schematic diagram of overall length imaging marker ruler device in this implementation.The overall length imaging marker ruler
Device includes：Making ruler 10 and bracket；The bracket includes：For clamping the making ruler hold assembly 20 of the making ruler 10；
For the height adjusting member 30 of aignment mark ruler height, one end of the height adjusting member 30 connects the making ruler clamping
Component；Edge of bed hold assembly 40 for connecting with patient bed, the edge of bed hold assembly 40 are another with height adjusting member 30
One end connection.
Referring to FIG. 2, being the structural schematic diagram of the making ruler 10.
The making ruler 10 includes scale portion 11 and the protrusion 12 positioned at length of the scale direction side, the protrusion
Fluted 13 are arranged on part 12.
The protrusion 12 is for being labeled the clamping of ruler hold assembly 20, thus the position of fixation mark ruler.This implementation
In example, the protrusion 12 is located at the side of scale portion 11, and the length of the protrusion 12 is less than scale portion
11 length can reduce the length of the making ruler hold assembly.In other embodiments of the invention, the protrusion
12 length is identical as the length of scale portion 11.
It is arranged fluted 13 on the making ruler protrusion 12.The groove can along making ruler 10 length or/and
The setting of thickness direction.
In the present embodiment, the groove 13 is along the length direction of making ruler, also, 12 upper and lower surface of the protrusion is equal
With groove 13.
In other embodiments of the invention, the groove 13 is located at the upper surface or lower surface of protrusion 12.
Referring to FIG. 3, for the diagrammatic cross-section in making ruler direction AA ' along Fig. 2 described in the present embodiment.
The making ruler 10（Please refer to Fig. 2）Including scale portion 11 and protrusion 12, the protrusion 12 it is upper
Lower surface has the groove 13 along making ruler length direction.
Referring to FIG. 4, for the carrier structure schematic diagram of overall length imaging marker ruler device in the present embodiment.
The bracket includes：Making ruler hold assembly 20；It is described for the height adjusting member 30 of aignment mark ruler height
One end of height adjusting member 30 connects the making ruler hold assembly 20；Edge of bed hold assembly for being connect with patient bed
40, the edge of bed hold assembly 40 is connect with the other end of height adjusting member 30.
The making ruler hold assembly 20 is used for clipped labels ruler 10（Please refer to Fig. 3）, the making ruler hold assembly 20
The interior notch 21 having along making ruler length direction, the size and making ruler protrusion 12 of the notch 21（Please refer to Fig. 3）
Size match：The length of the protrusion 12 of making ruler 10, the slot are equal or slightly larger than with the length of the notch 21
The width of mouth 21 is equal or slightly larger than the thickness of making ruler protrusion 12, and the depth of the notch 21, which is equal or slightly larger than, to be marked
The width of ruler protrusion 12.The notch 21 is for accommodating the making ruler protrusion 12.
Also there is making ruler fixing piece, the making ruler fixing piece can be ball head column in the making ruler hold assembly 20
Plug 22.The bulb plunger 22 is located in the side wall of the notch 21, can be located at the length direction of notch（Along the length of making ruler
Spend direction）Or/and width direction（Along the width direction of making ruler）, the stopper head of bulb plunger 22 is higher by sidewall surfaces.Also,
The size of the stopper head of the bulb plunger 22 and the groove 13 on the protrusion 12 of making ruler match.
In the present embodiment, the bulb plunger 22 is located in the side side wall of notch along its length, the bulb plunger
22 are evenly distributed in the side wall, and the quantity of the bulb plunger 22 is 7.In other embodiments of the invention, described
The quantity of bulb plunger 22 can also be 5,10,12 17 etc..
Referring to FIG. 5, clamping the diagrammatic cross-section after the making ruler 10 for the making ruler hold assembly 20.
The protrusion 12 of the making ruler 10 is located in notch 21, and the stopper head 221 of the bulb plunger 22 is higher than slot
The part of 21 sidewall surfaces of mouth is located in groove 13, and the making ruler is blocked, prevents it from deviating from easily.
Due to the spring structure at the top of bulb plunger 22 with stopper head 221 and positioned at 221 lower section of stopper head（In figure
It is not shown）, the spring structure keeps stopper head 221 scalable, so the protrusion 12 when making ruler 10 is inserted into the notch
When 13, the bulb plunger 22 is squeezed, is pressed into stopper head 221 in the cavity of bulb plunger 22.When the protrusion 12 into
Enter the notch 21, and when groove 13 is located at 22 top of bulb plunger, effect of the stopper head 221 in spring structure
Lower pop-up.The size of the stopper head 221 and the dimensional fits of groove 13, can prevent the making ruler 10 from deviating from.
When needing to extract the making ruler 10, under external force, 10 depresses plunger head 221 of making ruler makes the column
Chock plug 221 is pressed into, so that making ruler 10 be made to extract.
The making ruler hold assembly 20 can be stable clamp column described in making ruler 10 prevent, prevent making ruler 10 from clapping
It is moved during taking the photograph, subsequent image joint is caused to fail.
It quantity into and out external force size required for the making ruler 10 and the bulb plunger 22 and is distributed with
It closes, the quantity of the bulb plunger 22 is more, and distribution is more intensive, and required external force is bigger.
The bulb plunger 22 can also be distributed in the notch 21 along the width direction of notch（Along the thickness of making ruler 10
Direction）, thickness direction of the groove 13 on the protrusion 12 of the making ruler 10 also along the protrusion 12 is set accordingly
It sets.
In other embodiments of the invention, spring chuck can be set in the making ruler hold assembly, utilizes institute
It states spring chuck and clamps the making ruler.
Referring to FIG. 6, in the present embodiment, the partial schematic diagram of height adjusting member 30 and edge of bed hold assembly 40.
