Instrument for treatment of varus and valgus deformity and correction system including instrument

Abstract

The invention discloses an instrument for treatment of varus and valgus deformity and a correction system including the instrument. The instrument comprises a hollow-out correction barrel for the lower calf to be mounted and fixed to the lower leg, a support plate protruding out of the top of the correction barrel is further mounted at the top of the correction barrel, a first flexible matrix is fixed on the upper surface of the correction barrel, a second flexible matrix is fixed on the support plate, both the first flexible matrix and the second flexible matrix are communicated with an inflating piece inflating the matrixes, and the first flexible matrix and the second flexible matrix gradually and respectively expands to positions of the foot side and the sole of the varus and valgus foot after being bulged to push the varus and valgus foot to be corrected. By the arrangement, problems that an original varus and valgus foot correction instrument is inconvenient in use and pains are brought to patients during correction are solved; the flexible matrixes are adopted to press fore medial foot or lateral foot, heel medial, sole and astragalus anterior lateral, progressive regulation is adopted, user experience is good, and treatment effect is good.

Description

technical field [0001] The invention belongs to a foot correcting appliance, in particular to an appliance for treating varus and varus foot deformities. Background technique [0002] Valus foot is the most common clinical foot deformity in children. It is characterized by adduction and varus of the front half of the foot, calcaneus varus, plantar flexion, and contracture of the Achilles tendon showing equishoe deformity. The incidence rate of neonates is 1‰~4.5‰, the ratio of male to female is 2:1, more unilateral than bilateral. The sooner the treatment of congenital valgus and valgus is better, but the medical and economic conditions in poor areas are not good, and children often cannot receive timely treatment. Old clubfoot brings great physical, psychological and economic burdens to children, parents and society. Globally, obsolete equinus is the leading cause of disability among congenital musculoskeletal defects and is considered the most serious cause of disability...

AI Technical Summary

Problems solved by technology

[0003] At present, the internationally accepted treatment method for clubfoot is "Ponseti treatment", especially for the treatment of clubfoot in infancy. The child's foot is fixed with plaster at an angle and fixed in four to five times. During this period, the arch of the foot, manual reset, and accurate positioning of the talus are required. However, the child must go to the hospital every time to be operated by an experienced doctor. The skin of the child is easily injured during the process, and the child is more painful

Another method of treating clubfoot is surgical treatment. The plantar fascia is cut off, then sutured and bandaged, and then fixed with plaster, but the surgical treatment is painful, especially for newborn babies

In recent years, another method is to let the child wear a mechanical brace. The doctor uses the hand to turn the child's foot to an angle and then tightens the screw to maintain the angle. Generally, the child needs to go to the hospital for 5-6 times for correction. This method is very beneficial to the doctor. The technical requirements are high, and the angle of each pull is large. Due to the large brace, it cannot be used for newborns, and users cannot adjust it according to their own foot conditions.
