Description
Technical Field
The invention belongs to the technical field of medical instruments, and particularly relates to a portable photographing auxiliary device for axial X-ray films of knee joints.
Background
The knee joint is the most complicated joint of the human body, and due to the particularity of the position between the patella and the femur, when the patella has the pathological changes such as fracture, dislocation or patellofemoral joint osteoarthritis, the patella axial position sheet is necessary supplement for the normal knee joint ortholateral position. In the traditional patella axis position shooting method, the requirement on the position of a patient is high, or the shooting angle is not easy to master, so that the knee joint of the examined patient with pathological changes is uncomfortable, and the quality of the shot image is poor. Through the past work practice, it is necessary to improve the mold for patella use and the projection method.
The existing X-ray photographing device or photographing auxiliary device for the knee joint has the defects of no portability, difficult movement, incapability of adjusting the angle of the device according to the size of an individual patient and the like, so that the photographing effect is poor.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provides a portable photographing auxiliary device for axial X-ray of knee joints.
In order to achieve the purpose, the technical scheme provided by the invention is as follows:
the portable photographing auxiliary device for the X-ray axial position knee joint comprises a horizontal bottom plate (1), a bracket (2), a thigh placing plate (3), a shank placing plate (4), a lifting structure (5) and a foot hooking bracket (6); the support (2) is fixed on the horizontal bottom plate (1), the thigh placing plate (3) is hinged with the calf placing plate (4), and the hinged part of the thigh placing plate (3) and the calf placing plate (4) is fixed at the top of the support (2); one end, far away from the hinged part, of the thigh placing plate (3) is fixed on the horizontal base plate (1), and the shank placing plate (4) is connected with a lifting structure (5) fixed on the horizontal base plate (1); the foot hooking frame (6) is arranged on the horizontal bottom plate (1) and is close to one end of the lower leg placing plate (4).
Preferably, one side of the support (2) is provided with a patella horizontal position measuring rod (7) detachably connected with the support (2).
More preferably, one side of the bracket (2) is of a hollow sleeve structure, and the patella horizontal position measuring rod (7) is inserted into the hollow sleeve.
Preferably, a hard spongy cushion (8) with a middle ridge is arranged on the thigh placing plate (3).
Preferably, a lifting adjusting hand wheel (9) is arranged on the lifting structure (5).
More preferably, the lifting structure (5) is a diamond jack.
Preferably, collude foot rest (6) including connecting plate (10) that can move on horizontal bottom plate (1), be equipped with telescopic link (11) on connecting plate (10), telescopic link (11) top is equipped with colludes foot cylinder (12).
Preferably, the telescopic rod (11) is hinged with the connecting plate (10).
The portable photographing auxiliary device for the X-ray axial position knee joint is parallel to the X-ray.
The invention is further illustrated below:
in the invention, the hard sponge cushion of the middle ridge is covered on the thigh placing plate, so that the thigh can be comfortably placed on the thigh placing plate, and the distance between the two patellas can be fixed. The thigh placing plate is hinged with the shank placing plate, and the shank placing plate can move along with the hinged part to bend the knee joint. The patella horizontal position measuring rod is used for judging whether the patella joint surface is horizontal or not, and is detached after the position is measured during shooting so as to avoid developing. The lifting structure is used for lifting the lower leg placing plate. The foot hooking frame can move back and forth on the horizontal bottom plate, and the telescopic rod can stretch out and draw back to adapt to people with different heights. The purpose of the foot hooking frame is to press down the tiptoe part to prevent the tiptoe part from entering the shooting range and overlapping in the patellofemoral joint gap.
When shooting the X-ray of the axial position of the knee joint, the body position of the patient during shooting is adjusted according to the individual size of the patient and different anatomical forms of the patella, so that a standard axial position of the knee joint is shot. The portable medical bed is very portable, does not need to occupy a large amount of space, and can be used after being placed on a physical examination bed.
Compared with the prior art, the invention has the beneficial effects that:
1) comfortable body position
The examinee lies on the back on the photographic table, and the lower limbs are placed on the newly designed patella axis photographing mold, so that the knee joint is bent by about 45 degrees, the position of the patient is comfortable, and the knee joint is not uncomfortable due to extreme bending of the knee joint.
2) Knee joint bending angle is adjustable
The supporting structure with the height capable of being manually adjusted under the lower leg placing plate enables the knee joint angle to be adjusted to be parallel to the long axis of the patella and enables the knee joint angle to vertically take the film, so that the problem that quality is poor due to individual difference caused by different heights of the patella can be avoided, and X pieces with different bending angles of the knee joint can be shot according to clinical requirements.
3) Remote end hitch frame design
Can avoid the tiptoe from entering the range of the photograph and overlapping in the patellofemoral joint space.
4) Portable
The design is small and exquisite, has characteristics such as portable, easy operation. The X-ray auxiliary device has great help for conveniently and quickly shooting a standard knee joint axial X-ray.
