Description

Technical Field

[0001] The invention relates to a system and method for collecting comprehensive information on foot and ankle morphology. Background Art

[0002] For patients with congenital ankle and foot deformities, hindfoot inversion and valgus are often combined deformities; joint changes caused by chronic ankle instability, trauma or primary ankle arthritis are also accompanied by abnormal hindfoot force line. For such patients with foot and ankle deformities, the key to developing a reasonable treatment plan is to accurately assess the true situation of the hindfoot force line in the coronal plane.

[0003] At present, weight-bearing CT is an effective means to eliminate soft tissue, expose bone structure and avoid bone obstruction to reflect the real and accurate bone anatomical morphology of ankle and hindfoot, and can be used as the "gold standard" for force line measurement of foot and ankle. However, professional weight-bearing CT equipment for foot and ankle is expensive, and needs to be used with professional imaging software for stripping, positioning, measurement and other related operations, which is difficult to operate. Therefore, the application of weight-bearing CT in clinical practice is very limited and difficult to popularize.

[0004] Although computed tomography and magnetic resonance imaging can demonstrate coronal alignment of the hindfoot, these techniques lack practical utility in most clinical situations because the foot is imaged in the nonweight-bearing position.

[0005] X-ray is the most common imaging examination. Due to its two-dimensional limitation, standard anteroposterior, lateral and oblique X-rays of the foot or ankle cannot clearly show the force line of the tibia and calcaneus in the coronal plane. The Saltzman position (20°) X-ray is widely used in clinical practice, that is, the imaging plate is placed at an angle of 20° to the vertical direction, the two feet are parallel to the imaging plate, the X-ray tube of the X-ray machine is facing the midpoint of the line connecting the bilateral ankle joints, and the imaging is performed perpendicular to the imaging plate. The angle between the tibial axis and the calcaneal axis can be measured by the obtained X-ray film, and then the force line of the hindfoot can be evaluated. However, this method cannot clearly show the tibiotalar joint and the talar dome for cases with obvious abnormalities of the arch, such as flat feet or high arches, so it will seriously affect the accuracy of judging the force line of the hindfoot.

[0006] In addition, the lateral X-ray of the foot and ankle, the static appearance of the hindfoot force line in standing posture and the medial longitudinal arch of the foot, and the plantar pressure distribution, which are also of evaluation value, have been defined in clinical practice. However, in actual operation, patients need to collect them in different places, which is time-consuming and laborious, and the consistency of the collected information data is low, and the conclusions drawn from them will also be quite different. Therefore, a single method is usually used in clinical practice to collect and evaluate the information of the foot and ankle, which cannot make a holistic assessment of the patient, and the evaluation results have large errors.

[0007] In summary, it is necessary to explore a convenient, effective, simple and easy-to-operate method for collecting comprehensive information about the foot and ankle. Summary of the invention

[0008] In order to solve the problems that the existing methods for collecting foot and ankle morphology information have certain limitations, low feasibility, time-consuming and labor-intensive collection of comprehensive foot and ankle information, and low consistency of information data, the present invention now provides a system and method for collecting comprehensive foot and ankle morphology information.

[0011] The first platform, the second platform and the third platform are arranged in steps from low to high.

[0012] The information collection mechanism includes a first camera, a second camera, a footprint scanner, an X-ray machine, a T-shaped imaging plate and a binocular camera;

[0013] The first camera is arranged on one side of the first platform, and is used to capture a static appearance image of the medial longitudinal arch of a foot when the foot is weight-bearing;

[0014] The second camera is arranged at the other side of the second platform, and is used for taking a static appearance image of the medial longitudinal arch of the other foot when the other foot is weight-bearing;

[0015] The top surface of the second platform is provided with an opening; the footprint scanner is arranged inside the second platform, and its stepping scanning plate is embedded in the opening of the top surface of the second platform, and is used to scan and analyze the pressure distribution of the soles of the feet when the two feet are loaded;

[0016] The top surface of the third platform is provided with a T-shaped slot, and an angle adjustment mechanism is provided inside the third platform; the T-shaped imaging board includes a transverse board and a longitudinal board, wherein one end of the longitudinal board is vertically connected to the middle of the imaging surface of the transverse board, and both sides of the longitudinal board can be imaged; the T-shaped imaging board is inserted into the T-shaped slot, and the angle between the transverse board of the T-shaped imaging board and the vertical direction is adjusted by the angle adjustment mechanism;

[0017] The head of the X-ray machine can move around the third platform and perform three-dimensional position adjustment to take X-rays of the hindfoot force line and lateral positions of both feet;

[0018] The binocular cameras are arranged on both sides of the head of the X-ray machine, and are used to capture stereoscopic images of the appearance of both feet when the head of the X-ray machine moves.

[0019] Furthermore, the first platform is a movable flat plate, and the second platform and the third platform are both movable boxes; a storage opening is provided on the side of the third platform, and the first platform and the second platform can be placed inside the third platform through the storage opening.

[0020] Furthermore, the adjustment range of the angle between the transverse plate of the T-shaped imaging plate and the vertical direction is 10° to 30°.

[0021] Furthermore, the angle adjustment mechanism includes a support plate and a plurality of slots;

[0022] The support plate is arranged inside the third platform, and the plurality of card slots are arranged in parallel on the support plate and parallel to the transverse plate of the T-shaped imaging plate; the bottom edge of the transverse plate is carded in the card slot;

[0023] The top surface of the third platform is a transparent glass plate.

[0024] Furthermore, the number of the card slots is 5, and the corresponding angles are 10°, 15°, 20°, 25°, and 30° respectively.

[0025] Furthermore, a retractable handrail is provided on the third platform.

[0026] A method for collecting comprehensive information on foot and ankle morphology, using the above-mentioned comprehensive information collection system on foot and ankle morphology, is characterized in that it includes the following steps:

[0027] 1) One foot of the subject stands on the first platform, and the inner side of the foot faces the first camera, and the first camera is used to take a static appearance image of the inner longitudinal arch of the foot when the foot is weight-bearing; the other foot of the subject stands on the second platform, and the inner side of the other foot faces the second camera, and the second camera is used to take a static appearance image of the inner longitudinal arch of the other foot when the foot is weight-bearing;

[0028] 2) The subject stands on the second platform with both feet, and is located on the stepping scanning plate of the footprint scanner. The footprint scanner is used to scan and analyze the distribution of plantar pressure when both feet are bearing weight;

[0029] 3) The angle between the horizontal plate of the T-shaped imaging board and the vertical direction is set as the predicted angle. The subject's feet stand on the third platform, and are located on both sides of the longitudinal plate of the T-shaped imaging board, with both feet parallel to the horizontal plate of the T-shaped imaging board; X-ray films of the hindfoot force line and lateral positions of both feet are taken by an X-ray machine. At the same time, when the head of the X-ray machine moves, a stereoscopic image of the appearance of both feet is taken by a binocular camera.

[0030] Furthermore, in step 3), the X-ray films of the hindfoot force line and lateral positions of both feet are taken by an X-ray machine respectively as follows:

[0031] a) Adjust the position of the X-ray machine head so that the X-ray tube in the head is facing the outside of one foot and shoots perpendicularly to the longitudinal plate of the T-shaped imaging plate to obtain a lateral X-ray film of the foot;

[0032] b) Adjust the position of the X-ray machine head so that the X-ray tube in the head is facing the midpoint of the line connecting the bilateral ankle joints, and shoot perpendicularly to the horizontal plate of the T-shaped imaging plate to obtain the hindfoot force line X-ray films of both feet;

[0033] c) Adjust the position of the X-ray machine head so that the X-ray tube in the head is facing the outside of the other foot, and shoot perpendicularly to the longitudinal plate of the T-shaped imaging plate to obtain a lateral X-ray film of the other foot.

[0034] Furthermore, in the step 3), the predicted angle is predicted based on the degree of arch collapse; the greater the degree of arch collapse, the smaller the predicted angle.

[0035] Furthermore, in the step 1), when the first camera is used to capture the static appearance image of the medial longitudinal arch of the foot when it is weight-bearing, the subject is required to place the body center of gravity on the foot; when the second camera is used to capture the static appearance image of the medial longitudinal arch of the other foot when it is weight-bearing, the subject is required to place the body center of gravity on the other foot.

[0036] Compared with the prior art, the present invention has the following beneficial effects:

[0037] 1. The foot and ankle morphology comprehensive information collection system provided by the present invention can collect all kinds of relevant information about the foot and ankle of the subject at one time by the same person in the same environment and at the same time, including hindfoot force line and lateral X-rays of both feet, plantar pressure distribution and foot appearance characteristics, which greatly saves time cost and efficiency, and the collected information data has high consistency. Based on the comprehensive information of imaging, plantar pressure and appearance, it is helpful to accurately evaluate the deformity of the foot and ankle of the subject and formulate a reasonable treatment plan. Compared with weight-bearing CT, the system has a simple structure, is easy to operate, and has a low cost.

[0038] 2. The force line X-ray shooting of both feet is optimized based on the Saltzman position (20°), adding more shooting angles, which can be selected according to the degree of arch collapse of the subject. It can better show the force line of the tibia and calcaneus in the coronal plane and reduce the error caused by bone overlap.

[0039] 3. The first platform is designed as a movable flat plate, and the second and third platforms are designed as movable boxes, which are easy to move and store.

[0040] 4. The angle adjustment mechanism adopts the form of a card slot, which can realize fixed-point adjustment. It has a simple structure and the angle adjustment is fast and accurate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0049] In order to make the purpose, advantages and features of the present invention clearer, the following is a further detailed description of a foot and ankle morphology comprehensive information collection system and method proposed by the present invention in combination with the accompanying drawings and specific embodiments. It should be noted that the accompanying drawings are in a very simplified form and use non-precise proportions, which are only used to conveniently and clearly assist in explaining the embodiments of the present invention.

[0050] The comprehensive ankle morphology information collection system provided in this embodiment is as follows: Figures 1 to 6 As shown, it includes a first platform 1, a second platform 2, a third platform 3 and an information collection mechanism.

[0051] The first platform 1 is a rectangular movable flat plate, and the second platform 2 and the third platform 3 are both rectangular movable boxes. The first platform 1, the second platform 2, and the third platform 3 are arranged in a step-like manner from low to high.

[0052] The information collection mechanism includes a first camera 4 , a second camera 5 , a footprint scanner 6 , an X-ray machine 7 , a T-shaped imaging plate 8 and a binocular camera 9 .

[0053] like Figure 4 , Figure 5 As shown, the first camera 4 is arranged on the left side of the first platform 1, and is used to take a static appearance image of the medial longitudinal arch of the right foot when the foot is weight-bearing. The second camera 5 is arranged on the right side of the second platform 2, and is used to take a static appearance image of the medial longitudinal arch of the left foot when the foot is weight-bearing.

[0054] An opening is provided on the top surface of the second platform 2, and a footprint scanner 6 is arranged inside the second platform 2. Its stepping scanning plate 61 is embedded in the opening on the top surface of the second platform 2 and is flush with the top surface of the second platform 2, and is used to scan and analyze the pressure distribution of the soles of the feet when both feet are bearing weight.

[0055] A T-shaped slot 31 is provided on the top surface of the third platform 3 , and a transverse groove of the T-shaped slot 31 is close to the top surface of the third platform 3 and away from the second platform 2 . An angle adjustment mechanism is provided inside the third platform 3 .

[0056] The T-shaped imaging board 8 is composed of a rectangular transverse board 81 and a rectangular longitudinal board 82. One end of the longitudinal board 82 is vertically connected to the middle of the imaging surface of the transverse board 81, and both sides of the longitudinal board 82 can be imaged. The T-shaped imaging board 8 is inserted into the T-shaped slot 31, and the angle between the transverse board 81 of the T-shaped imaging board 8 and the vertical direction is adjusted by the angle adjustment mechanism, that is, the inclination angle of the transverse board 81 of the T-shaped imaging board 8 away from the second platform 2. The angle adjustment range is 10° to 30°, which can meet the imaging requirements. It should be noted that the width of the transverse slot 31 of the T-shaped slot 31 should meet the activity space of the transverse board 81 of the T-shaped imaging board 8 during angle adjustment, the length of the longitudinal slot 31 of the T-shaped slot 31 should meet the activity space of the longitudinal board 82 of the T-shaped imaging board 8 during angle adjustment, and the height of the transverse board 81 of the T-shaped imaging board 8 should meet the complete imaging of the tibia and calcaneus at different inclination angles.

[0057] There are many implementation forms of the angle adjustment mechanism, such as pushing and pulling the lower end of the horizontal plate 81 of the T-shaped imaging plate 8 by a motor or a cylinder, thereby continuously changing the angle between the horizontal plate 81 and the vertical direction. This embodiment now provides a form with a relatively simple structure, high reliability, and fast and accurate angle adjustment.

[0058] like Figure 2 , Figure 3As shown, the angle adjustment mechanism includes a support plate 32 and five slots 33. The support plate 32 is arranged inside the third platform 3 and is parallel to the top surface of the third platform 3. The five slots 33 are arranged in parallel on the support plate 32 and are parallel to the transverse plate 81 of the T-shaped imaging plate 8. The height of the transverse plate 81 of the T-shaped imaging plate 8 is slightly greater than the height of the longitudinal plate 82. After the longitudinal plate 82 is connected to the transverse plate 81, the upper ends of the two are flush, and the bottom edge of the transverse plate 81 is clamped in the slot 33. The five slots 33 correspond to angles of 10°, 15°, 20°, 25°, and 30°, respectively. Of course, slots 33 corresponding to other angles can also be set as needed. When adjusting the angle, it is only necessary to manually lift the T-shaped imaging plate 8 and clamp it into the slot 33 corresponding to the required angle. It is convenient and quick, and does not require complex electrical control. In order to accurately insert the transverse plate 81 into the slot 33 corresponding to the required angle, one side plate of the third platform 3 can be removed or set as a transparent plate, and the corresponding angle is marked on one side of each slot 33 for easy observation. In this embodiment, the top surface of the third platform 3 is set as a non-spliced ​​transparent glass plate, which is convenient for observing the slot 33 below on the one hand, and avoids the splicing from affecting the imaging on the other hand.

[0059] The head 71 of the X-ray machine 7 can move around the third platform 3 and perform three-dimensional position adjustment, and is used to take hindfoot force line and lateral X-ray films of both feet. When taking pictures, the X-ray tube in the head 71 needs to be perpendicular to the imaging plate. The position adjustment of the head 71 of the X-ray machine 7 is achieved through the structure of the X-ray machine 7 itself, which is a prior art.

[0060] The binocular cameras 9 are arranged on both sides of the head 71 of the X-ray machine 7, and are used to capture stereoscopic images of the appearance of both feet when the head 71 of the X-ray machine 7 moves.

[0061] In order to facilitate storage and movement, a storage opening is opened on the side of the third platform 3, and the space below the support plate 32 is the storage space. The first platform 1 and the second platform 2 can be placed in the storage space inside the third platform 3 through the storage opening. Figure 6 shown.

[0062] Since the person being collected may be standing unsteadily, in order to prevent waste of X-ray films due to shaking during X-ray filming, a height-adjustable telescopic armrest 10 is provided on the third platform 3 to accommodate the use of persons of different heights and to facilitate compression and storage.

[0063] The top surfaces of the first platform 1, the second platform 2, and the third platform 3 are all provided with standing position markings, such as footprint stickers, etc. The person being collected can stand directly at the position of the footprint stickers to ensure that the relative position is fixed and improve the efficiency of information collection.

[0064] The method for collecting information using the above-mentioned comprehensive information collection system for foot and ankle morphology comprises the following steps:

[0065] 1) The subject’s right foot stands on the first platform 1, and the inner side of the right foot faces the first camera 4. At this time, the left foot can stand on the second platform 2 or be suspended in the air, ensuring that the subject’s body center of gravity is placed on the right foot, and the right foot is in a weight-bearing state. The first camera 4 takes a static appearance image of the medial longitudinal arch of the right foot when the right foot is weight-bearing; The subject’s left foot stands on the second platform 2, and the inner side of the left foot faces the second camera 5. At this time, the right foot can stand on the third platform 3 or be suspended in the air, ensuring that the subject’s body center of gravity is placed on the left foot, and the left foot is in a weight-bearing state. The second camera 5 takes a static appearance image of the medial longitudinal arch of the left foot when the left foot is weight-bearing. The weight-bearing position image of the foot can better display the morphology of the medial longitudinal arch.

[0066] 2) The subject's feet stand on the second platform 2 and are located on the stepping scanning plate 61 of the footprint scanner 6. The footprint scanner 6 scans and analyzes the distribution of plantar pressure when the feet are weight-bearing.

[0067] 3) The angle between the transverse plate 81 of the T-shaped imaging board 8 and the vertical direction is set to be the pre-judged angle, and the subject's feet stand on the third platform 3, and are respectively located on both sides of the longitudinal plate 82 of the T-shaped imaging board 8, and the feet are parallel to the transverse plate 81 of the T-shaped imaging board 8; the hindfoot force line and lateral X-ray films of the feet are respectively taken by the X-ray machine 7, and at the same time, the stereoscopic image of the appearance of the feet is taken by the binocular camera 9 during the movement of the head 71 of the X-ray machine 7.

[0068] The predicted angle is predicted based on the degree of arch collapse. The greater the degree of arch collapse, the smaller the predicted angle. For flat-foot patients, the degree of arch collapse is relatively large. When the angle between the horizontal plate 81 of the T-shaped imaging plate 8 and the vertical direction is set to 10°, the X-ray film taken can accurately reflect the degree of hindfoot eversion, such as Figure 7 For patients with high arches, when the angle between the transverse plate 81 of the T-shaped imaging plate 8 and the vertical direction is set to 30°, the X-ray film taken can accurately reflect the degree of hindfoot inversion.

[0069] The specific process of taking the hindfoot force line and lateral X-ray films of both feet by the X-ray machine 7 is as follows:

[0070] a) adjusting the position of the head 71 of the X-ray machine 7 so that the X-ray tube in the head 71 is facing the outside of a foot and photographing perpendicularly to the longitudinal plate 82 of the T-shaped imaging plate 8 to obtain a lateral X-ray film of the foot;

[0071] b) adjusting the position of the head 71 of the X-ray machine 7 so that the X-ray tube in the head 71 is facing the midpoint of the line connecting the bilateral ankle joints, and taking pictures perpendicular to the transverse plate 81 of the T-shaped imaging plate 8 to obtain the hindfoot force line X-ray films of both feet;

[0072] c) Adjust the position of the head 71 of the X-ray machine 7 so that the X-ray tube in the head 71 faces the outside of the other foot and shoots perpendicularly to the longitudinal plate 82 of the T-shaped imaging plate 8 to obtain a lateral X-ray film of the other foot.

[0073] 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 to preliminarily judge the severity of the deformity and pathological manifestations: judge the "polydactyly" according to the posterior view, judge the "degree of collapse of the medial arch of the foot" according to the medial view, and judge the "degree of eversion of the lateral fat pad of the heel" according to the lateral view; the hindfoot force line position and lateral X-ray film of both feet taken by the X-ray machine 7 can be used to judge the degree of bone deformity other than soft tissue, and the perioperative surgical prediction, such as: whether surgery is needed, whether osteotomy is needed, the osteotomy site and the degree of osteotomy displacement; the plantar pressure distribution collected by the footprint scanner 6 is compared with the plantar pressure distribution of normal people, and the severity of the rotation deformity of the foot, the abnormal load point and the stability of the foot when loading can be further obtained. The comprehensive information of the foot and ankle collected by the information collection system and method provided by the present invention is more accurate and reliable than the information collected by a single method. For patients with foot and ankle deformities, one-time collection and evaluation can be achieved, which is convenient and fast, has little harm to the body, and has high consistency of information data, which helps to reduce errors.
