Abstract

The invention relates to an adjustable fixation device for trauma orthopedics. It includes a base ring, a slewing ring and a fixed ring on both sides, and a plurality of tensioners are respectively installed on the slewing ring, the base ring and the fixed ring; the base ring includes an outer ring of the base ring and a parallel The inner ring of the base ring with it as the track, the inner ring of the base ring is a toothed ring with teeth on the outer edge, and an adjusting bolt with a gear in the middle is installed on the outer ring of the base ring, and the adjusting bolt and the base ring Inner ring tooth meshing transmission, each tensioner on the base ring is installed on the outer ring of the base ring and the inner ring of the base ring; the slewing ring includes the slewing ring body, the fixed ring includes the fixed ring body, A plurality of first connecting rods are arranged between the slewing ring body and a plurality of second connecting rods are arranged between the outer ring of the base ring and the fixed ring body. The invention has a reasonable structural design, and because of the adjustable feature, the convenience of operation is improved, and the accuracy, effectiveness and reliability of fixing are improved at the same time.

Description

technical field [0001] The invention belongs to the technical field of trauma orthopedics supplies, in particular to an adjustable fixing device for trauma orthopedics. Background technique [0002] Clinically, traumatic orthopedics mainly refers to diseases caused by external forces and trauma, such as limb fractures, lumbar fractures and joint dislocations, joint ligament injuries, meniscus injuries, and muscle and soft tissue injuries. Trauma orthopedics is one of the important departments in modern clinical practice. In terms of clinical content, it refers to fractures and dislocations, ligament and tendon injuries caused by trauma. The main traumas include car accident injuries, mechanical strains, and blow injuries. Children and the elderly will slip and fall , fall. Fractures caused by trauma are often combined with severe soft tissue injuries, sometimes violently, and the bone fragments will puncture the skin to cause open fractures, which are difficult to deal with...
