The present application relates to the technical field of point cloud data analysis, and particularly relates to an auxiliary evaluation system for foot deformity based on computer vision, which comprises the following steps: collecting foot data to be evaluated and normal foot data at each moment, and dividing point cloud data in the foot data into forefoot point cloud data, midfoot point cloud data and hindfoot point cloud data; extracting feature points in the forefoot point cloud data, the midfoot point cloud data and the hindfoot point cloud data, constructing a plurality of units of foot data, and further screening reliable foot state units and comparison units at each moment; and obtaining the abnormal degree of the foot data to be evaluated according to the angle deformity factor, the support vector deformity factor and the support vector deformity factor of the reliable foot state units at each moment, so as to assist in evaluating whether the patient's foot is deformed. The present application analyzes and compares the dynamic differences between the foot point cloud data of the patient and the normal point cloud data, so as to improve the reliability of the auxiliary evaluation of foot deformity.

The application relates to the technical field of surgical assistance, and discloses a foot deformity correction surgery planning and implementation method, which comprises the following steps: fusing multi-modal medical images and dynamic function data to construct a high-fidelity foot digital twin model; intelligently quantitatively evaluating and mechanismally analyzing deformities by using a deep learning network combined with a knowledge graph; automatically optimizing in a virtual space by using a multi-agent reinforcement learning algorithm to generate a personalized surgery plan verified by biomechanical simulation; converting the optimized scheme into augmented reality navigation information and robot control instructions to guide a surgical robot to perform adaptive and accurate osteotomy and reduction operations; dynamically evaluating execution deviations and guiding correction by using real-time three-dimensional scanning and registration technology during the operation, and intelligently matching and implanting internal fixators; immediately performing function verification after the operation, and generating a personalized digital rehabilitation scheme and long-term curative effect prediction for the patient based on the operation result. The application constructs an intelligent surgery ecological system throughout the whole process of "diagnosis, planning, implementation, evaluation and management", and significantly improves the accuracy, safety, predictability and scientific level of curative effect management of foot deformity correction surgery.

The invention discloses children congenital hand and foot deformity correction equipment, and relates to the technical field of biomedical engineering. The correcting device comprises a position-adjustable spring steel plate base assembly and a correcting part. The correcting part is composed of an adjusting extending frame, a first lead screw, a second lead screw and a plurality of corresponding clamping frames, and a correcting cotton cushion block capable of being pushed in a rotating mode is arranged in each clamping frame and used for gradually clamping non-finger joint parts to conduct mild correction. The lead screw and the clamping frame are in rotary fit, and axial or rotary displacement of the lead screw and the clamping frame is limited through the locking shaft sleeve and the screw rod. A locking base plate is arranged on the side of the spring steel plate and provided with four binding belts capable of being automatically tightened and a gear sleeve, a poking wheel, a gear and a rack linkage mechanism matched with the binding belts, and the poking wheel is rotated to drive the binding belts to be synchronously tightened and achieve self-locking. The sponge pad is used for buffering and attaching to palms or soles.

To solve problems of footwear for foot deformity disorder, the problems in which commercially available ready-made footwear has an insole designed on the average data of human foot and naturally it is a difficult task to find ready-made footwear that fits individual user's foot, in which, particularly a user having a lesion in the foot often experiences pain in footwear with no footwear available that has effect for correcting a lesion, and in which although custom-made footwear is better than ready-made footwear in the fidelity of the last, there is no remedial effect at all for a foot having a lesion.SOLUTION: Projection is made for the sole of a user in a total of five parts which are in addition to three parts in Fig. 2 for the ball of a big toe 9, the balls of other toes 10, and a heel 11, and two parts for a big toe 8 and a little toe 7. As shown in Fig. 1, the five parts of the marks 2, 3, 4, 5, 6 are notched or drilled, and the insole 1 in which each part is fit in the inner sole of the footwear is spread on the inner sole of the footwear, otherwise the insole 1 is fabricated into the inner sole of the piece of footwear to make an integrated structure.SELECTED DRAWING: Figure 1
