Technical Field

The invention relates to a system and a method for acquiring comprehensive information of ankle form.

Background

For patients with congenital ankle and foot deformity, hind-foot varus and hind-foot often appear as combined deformity; joint changes caused by chronic ankle instability, trauma, or primary ankle arthritis, etc., are also associated with abnormalities in the hindfoot line. For the ankle deformity patients, the key for making a reasonable treatment scheme is to accurately evaluate the true situation of the hind foot line under the coronal plane.

At present, for reflecting real and accurate bony anatomical morphology of the ankle and the hind foot, the weight bearing CT is an effective means which can remove soft tissues, simply expose bony structures and has no bony barrier, and can be used as a 'gold standard' for measuring the force line of the ankle. However, the load CT apparatus for ankle speciality is expensive, and requires to cooperate with specialized imaging software to perform the related operations such as stripping, positioning, measuring, etc., and the operation difficulty is large, so the application of the load CT in clinic is very limited, and it is difficult to popularize.

Although computer tomography and magnetic resonance imaging techniques can show the hind-foot coronal alignment, they are of limited utility in most clinical situations because the foot is imaged in a non-weight bearing position during the examination.

X-ray is the most common imaging examination, and because of its two-dimensional limitations, standard orthostatic, lateral and oblique X-ray films of the foot or ankle are not able to clearly show the force lines of the tibia and calcaneus in the coronal plane. The clinical application is that Saltzman position (20 degree) X-ray is shot widely, namely the imaging plate is placed at an included angle of 20 degrees with the vertical direction, the two feet are parallel to and face the imaging plate, and the X-ray bulb of the X-ray machine is right opposite to the middle point of the connecting line of the ankle joints at the two sides and is vertical to the imaging plate for shooting. The included angle between the tibia axis and the calcaneus axis is measured through the obtained X-ray film, and then the condition of the hind foot force line can be evaluated. However, in the case of obvious arch abnormality, such as flat foot or high arch foot, the tibialis distance joint and talar vault cannot be clearly displayed, and therefore the accuracy of judging the hindfoot line is seriously affected.

In addition, although the ankle lateral X-ray film, the hindfoot force line in the standing position, the static appearance of the medial arch part of the foot, the plantar pressure distribution, and the like, which also have evaluation value, are defined in clinical practice, in actual operation, the patient needs to collect data in different places, which wastes time and labor, and the consistency of the collected information data is low, so that the obtained conclusions are also greatly different. Therefore, in clinic, a single method is usually adopted to collect the ankle information and evaluate the ankle information, the overall evaluation of the patient cannot be carried out, and the evaluation result has large errors.

In summary, a method for collecting comprehensive information of the ankle, which is convenient, effective, simple and easy to operate, needs to be found.

The second camera 5 is provided on the right side of the second platform 2 and is used for capturing a static appearance image of the inner longitudinal arch part when the left foot is loaded.

The top surface of second platform 2 is equipped with the opening, and footprint scanner 6 sets up inside second platform 2, and it tramples in scanning board 61 imbeds the opening of second platform 2 top surface, and level with second platform 2 top surface for the sole pressure distribution condition when scanning analysis both feet bear a burden.

The T-shaped imaging plate 8 is composed of a rectangular transverse plate 81 and a rectangular longitudinal plate 82, one end of the longitudinal plate 82 is vertically connected with the middle of an imaging surface of the transverse plate 81, and both side surfaces of the longitudinal plate 82 can be imaged. T type formation of image board 8 inserts in T type slot 31 to adjust the horizontal board 81 of T type formation of image board 8 and the contained angle of vertical direction through angle adjustment mechanism, namely the horizontal board 81 of T type formation of image board 8 is to keeping away from the inclination of 2 one sides of second platform, and the contained angle control range is 10 ~ 30, can satisfy the formation of image demand. It should be noted that the width of the transverse slot of the T-shaped slot 31 should satisfy the movement space of the transverse plate 81 of the T-shaped imaging plate 8 during the angle adjustment, the length of the longitudinal slot of the T-shaped slot 31 should satisfy the movement space of the longitudinal plate 82 of the T-shaped imaging plate 8 during the angle adjustment, and the height of the transverse plate 81 of the T-shaped imaging plate 8 should satisfy the complete imaging of the tibia and the calcaneus under different inclination angles.

The angle adjusting mechanism is implemented in many forms, such as pushing and pulling the lower end of the transverse plate 81 of the T-shaped imaging plate 8 by a motor or an air cylinder, so as to continuously change the included angle between the transverse plate 81 and the vertical direction.

The method for acquiring the information by adopting the ankle form comprehensive information acquisition system comprises the following steps:

1) the right foot of the person to be collected is placed on the first platform 1, the inner side of the right foot is opposite to the first camera 4, the left foot can be placed on the second platform 2 or suspended in the air at the moment, the body gravity center of the person to be collected is placed on the right foot, the right foot is in a load bearing state, and the first camera 4 is used for shooting a static appearance image of the inner longitudinal arch part when the right foot bears load; the left foot of the person to be collected stands on the second platform 2, the inner side of the left foot is opposite to the second camera 5, the right foot can stand on the third platform 3 or be suspended, the body gravity center of the person to be collected is placed on the left foot, the left foot is in a load bearing state, and the second camera 5 is used for shooting a static appearance image of the inner longitudinal arch part when the left foot bears load. The foot load position image can better display the shape of the inner longitudinal arch part.

2) The feet of the person to be collected stand on the second platform 2 and are positioned on the treading scanning plate 61 of the footprint scanner 6, and the distribution condition of the pressure on the soles of the feet when the feet bear weight is scanned and analyzed by the footprint scanner 6.

3) Setting an included angle between a transverse plate 81 of the T-shaped imaging plate 8 and the vertical direction as a pre-judgment angle, standing two feet of a person to be collected on the third platform 3, and respectively locating at two sides of a longitudinal plate 82 of the T-shaped imaging plate 8, wherein the two feet are parallel to and opposite to the transverse plate 81 of the T-shaped imaging plate 8; the X-ray machine 7 is used for shooting the X-ray films of the rear foot force line position and the side position of the feet respectively, and meanwhile, the machine head 71 of the X-ray machine 7 is used for shooting the stereoscopic images of the appearances of the feet through the binocular camera 9 in the moving process.

b) adjusting the position of a machine head 71 of the X-ray machine 7 to ensure that an X-ray bulb tube in the machine head 71 is over against the middle point of the connecting lines of the ankle joints at the two sides and is vertical to a transverse plate 81 of the T-shaped imaging plate 8 for shooting to obtain a hindfoot force line X-ray film of the two feet;

c) and adjusting the position of the machine head 71 of the X-ray machine 7 to ensure that the X-ray bulb tube in the machine head 71 is over against the outer side of the other foot and is vertical to the longitudinal plate 82 of the T-shaped imaging plate 8 for shooting to obtain a side X-ray film of the other foot.

In the above method, the appearance images captured by the first camera 4, the second camera 5 and the binocular camera 9 can be used for preliminary judgment of the severity of deformity and pathological manifestations: judging the 'multitoe sign' according to the rear side view, judging the 'medial arch collapse degree' according to the medial side view, and judging the 'heel lateral fat pad eversion degree' according to the lateral side view; the biped hindfoot force line position and lateral position X-ray piece shot through the X-ray machine 7 can be used for bone malformation degree judgment except soft tissue and perioperative operation prejudgment, such as: whether an operation is required, whether an osteotomy is required, the osteotomy site and the osteotomy displacement degree; the plantar pressure distribution acquired by the footprint scanner 6 is contrasted with the plantar pressure distribution of a normal person for analysis, so that the severity of foot rotation deformity, abnormal stress points and the stability of the foot during load bearing can be further obtained. Compared with the information acquired by a single method, the comprehensive information of the ankle acquired by the information acquisition system and the method provided by the invention is more accurate and reliable. For ankle deformity patients, the method can realize one-time acquisition and evaluation, is convenient and rapid, has little harm to bodies, has high information data consistency, and is favorable for reducing errors.
