Distraction apparatus for the treatment of complex forms of hand syndactyly in children

摘要

The useful model relates to the field of medicine, namely to the field of traumatology, to a distraction device for the treatment of complex forms of hand syndactyly in children and can be used in the treatment of patients in traumatological and orthopedic, surgical and other hospitals. The objective of the useful model is to create a distraction device for treatment of complex forms of hand syndactyly in children, a technical result, the use of which is to ensure sufficient anatomical restoration of the shape and support function of the hand in children, ensure the adaptation of the apparatus to deformity of the fingers, increase the efficiency of the distraction performed, ensure the possibility of computed tomography with a minimum number of artifacts , a significant reduction in the weight of the distraction apparatus, a reduction in the duration and trauma of surgical intervention and in the process of performing distraction, while improving the patient's quality of life. is the fact that a distraction device for the treatment of complex forms of hand syndactyly in children is proposed, characterized by the fact that it is made in the form of two identical fixing arcs 5 mm thick, bent with a radius of curvature of 15 mm and connected in pairs using fixing distraction threaded rods with a diameter of 3 mm and a length of 35-45 mm with a thread throughout, while each fixing distraction threaded rod is equipped with fixation elements in the form of hex nuts in the amount of 4 pieces, fixing distraction threaded rods are placed in through holes 3.2 mm in diameter made in each protruding plate with a thickness of 2.5 mm, located at the apex and at the ends of each arm of the fixing arcs, 10 through holes with a diameter of 1.2 mm are made in the arms of two identical fixing arcs for placement during surgical intervention in each fixing arc from 3 to 4 wires, and the distance between the axes of the through holes is chosen 5 mm, at the ends of f The fixing arcs of the apparatus are beveled at an angle of 45 ° on each inner side and bevels at an angle of 70 ° on each of their outer sides, while the fixing arcs of the distraction apparatus are made of a biocompatible polymer material based on polyarylene ether ketone containing, as polyarylene ether ketone, a biocompatible polymer material, polyarylene ether ketone, selected from the group polyetheretherketone, polyetheretherketone, polyetheretherketone or polyetheretherketone.
