Kneecap is in metastable camera plane when saving buckling.In addition, existing apparatus is not set for digitized image receiver board
Hold horse, during so as to shoot can not stationary digital image receiver board, can not also ensure the X-ray of X-ray tube outgoing always with number
It is vertical to change image receiver board.
Utility model content
In view of this, the utility model provides a kind of patellofemoral joint dynamic axle position X-ray photographic angle regulator, can
Accurate angle positioning is carried out to patient's knee sprung, the low-angle of realization knee flexion angle is increased continuously and can be in angle
Ensure that kneecap is in stable camera site, in combination with holding horse come incidence x-ray and number when ensuring each angle during variation
Word image receiver board is vertical.
A kind of patellofemoral joint dynamic axle position X-ray photographic angle regulator, the device include pedestal, angle board, gas spring,
Sliding sleeve, litter and hold horse component；
The pedestal forms inverted T font structure by horizontal component and vertical portion, and horizontal component is placed on ground, plays branch
The effect of whole device is supportted, the symmetrical top for being movably connected in vertical portion of two pieces of angle boards, two slide bars, which are fixed, to be connected
The both sides of vertical portion are connected on, the slide bar is perpendicular to the horizontal component of pedestal；The sliding sleeve is sleeved on slide bar and and slide bar
To be slidably matched, the both ends of the gas spring are hinged respectively with the bottom of angle board and sliding sleeve；The horizontal component of the pedestal
Side is fixedly mounted and holds horse component, holds horizontal component of the horse component perpendicular to pedestal, holds horse component for installing number
Change image receiver board and adjustable tilt angle.
Further, the horse component of holding includes holding horse sleeve, holding horse sliding block and locking nut；It is described to hold horse
Sleeve is two, two are held the surface that horse sleeve is vertically fixedly connected on the horizontal component of pedestal, the horse sliding block of holding
One end is machined with card slot along its length along end face, and card slot is used to place digitized image receiver board；It is described to hold horse sliding block
Insertion holds horse sleeve inner and is slidably matched with holding the formation of horse sleeve, and the locking nut is by holding the screw thread on horse sleeve
Hole stretch into hold horse sleeve inner locking hold horse sliding block.
Further, the gas spring uses balanced type gas spring.
Advantageous effect：
1st, the utility model is realized using the linear length variation characteristic of gas spring to two pieces of angle board relative angles
Linear regulation can be realized and take the photograph piece to the Dynamic X-ray of patellofemoral joint axle position, can not only meet the shooting of special angle, also can root
Factually the detection on border needs to be adjusted to required angle.
2nd, the utility model will be held horse component and is arranged on the horizontal component of pedestal, ensure number by holding horse sleeve
The verticality of word image receiver board and horizontal plane, so that the X-ray of X-ray tube outgoing is vertical with digitized image receiver board,
Ensure shooting image quality.
3rd, the utility model is adjusted by holding to hold horse sleeve in horse component and hold the slide displacement between horse sliding block
The level height of digitized image receiver board is saved, regulative mode is simple and reliable.

Specific embodiment
With reference to the accompanying drawings and examples, the utility model is described in detail.
As shown in figure 1 and 2, the utility model provides a kind of patellofemoral joint dynamic axle position X-ray photographic angular adjustment dress
It puts, which includes pedestal 1, angle board 2, gas spring 3, sliding sleeve 4, litter 5 and hold horse component；Horse component is held to include holding piece
Frame sleeve 6 holds horse sliding block 7 and locking nut 8；
Gas spring 3 in the present embodiment uses balanced type gas spring.
Pedestal 1 forms inverted T font structure by horizontal component and vertical portion, and horizontal component is placed on ground, plays support
