Abstract

According to an adjustable talipes equinovarus correction device based on 3D printing, a shank part, a heel part and a front sole part are connected with one another through connecting bodies arrangedon the two sides; each connecting body comprises a front connecting rod, a front connecting part, a rear connecting part and a main joint; one end of each front connecting rod is connected with the front sole part, and the other end of each front connecting rod is connected with the corresponding main joint through the corresponding front connecting part; one end of each rear connecting part is connected with the heel part, and the other end of the rear connecting part is connected with the corresponding main joint; each main joint is connected with the shank part; the shank part covers 60% of the area of a shank and opens forwards; the heel part covers calcaneus in a hemisphere wrapping mode and stops at a talus body below lateral malleolus; and the front sole part covers the front solein a semi-wrapping mode and comprises first to fifth metatarsal bones and first to fifth near-end and far-end phalanxes, and opens upwards. On the basis of ankle dissection, instrument innovation andclinical application, the correction device adjusts the correcting force on the two sides in a personalized mode according to the deformity condition of a patient, so that the purpose of effectively correcting deformity is achieved, and a new external fixation orthopedic technical system is formed.

Description

technical field [0001] The invention relates to the field of clubfoot correction, in particular to an adjustable clubfoot correction device based on 3D printing. Background technique [0002] Clubfoot is the most common deformity of the lower extremities in clinical practice. The etiology is complex. It is characterized by adduction of the forefoot, high arch of the midfoot, varus of the hindfoot, and plantarflexion deformity, which gradually aggravates with age. The incidence rate of newborns is 1‰~4.5‰, and the ratio of male to female is 2:1, with more unilateral than bilateral. Clubfoot deformity not only severely damages the normal function of the foot and affects the daily life of patients, but also causes a series of secondary problems such as unequal length of lower limbs, pelvic tilt, and scoliosis. The mainstay of treatment available is the ponseti sequence of plaster casts. [0003] The ponseti sequence plaster orthopedic method begins to perform plaster orthoped...
