Embodiment Construction
[0017] The present invention will be further described below through non-limiting embodiments in conjunction with the accompanying drawings.
[0018] An external fixator for bone lengthening figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 As shown, an external fixation bracket for bone lengthening is mainly composed of half-ring connecting rods, bone needles, extender parts and support rods. The half-ring connecting rods are in the shape of an open pentagon, and two are arranged in parallel at the upper and lower positions. Two supporting rods are arranged in parallel at the two ends of the central edge of the half-ring connecting rod in an axial equidistance, and the two ends are respectively fastened and connected with the half-ring connecting rod through rod fastening clips. Bone needles are respectively arranged at the two ends and the center of the half-ring connecting rod, and are fastened and connected with the half-ring connecting rod through needle rod fa...

The invention discloses an external fixation support for bone lengthening, which mainly comprises semicircular connecting rods, bone needles, lengthener components and support rods, wherein the two semicircular connecting rods are shaped like an open pentagon and arranged up and down in parallel; the two support rods are equidistantly arranged in parallel at the ends of the central edges of the semicircular connecting rods in the axial direction; the ends of the support rods are in fastened connection with the semicircular connecting rods via rod-rod fastening clips respectively; the bone needles are simultaneously arranged at the ends and the central positions of the semicircular connecting rods respectively; the bone needles are in fastened connection with the semicircular connecting rods via needle-rod fastening clips respectively; and the lengthener components comprise the support rods, locking nuts, adjusting core rods and adjusting handles. The external fixation support has the advantages of simple structure, low manufacturing cost, small size, firmness and reliability in fixation and convenient and simple operational program, and is a multifunctional external fixation support that can fulfill fixation and pressurization and also can realize malformation correction or lengthening of bones.
Description
technical field [0001] The invention belongs to the field of medical devices, and in particular relates to an external fixation bracket for bone lengthening. Background technique [0002] The external fixation bracket is connected and fixed with the external device through the steel needle inserted in the bone, and exerts axial pressure and traction on the bone (extending the limb or bone segment). It is the most commonly used surgical method in the treatment of long bone fractures and deformity correction in clinical orthopedics. In the prior art, external fixation brackets include unilateral external fixation brackets, hook-groove external fixation brackets, and ring-shaped external fixation brackets. Its main function is to fix and pressurize the broken limb, prevent the twisting and deformation of the broken bone, and promote the healing of the fracture, but it cannot achieve the therapeutic effect of correcting or prolonging the deformity of the bone.
