Problems solved by technology

[0005] However, the existing external fixator 9 is set around the broken bone B1 and the broken bone B2, and cannot directly attach to the patient's limbs. The existing external fixator 9 also has more complicated components, so that This existing bone external fixator 9 not only has the problem of bulkiness, but also has the problem of heavy weight, so it will burden the daily life of the patient, which is really inconvenient

Abstract

An external fixator for bone, which can be applied in bone transport or bone lengthening, includes: a bone plate, which includes several bone positioning holes; and an adjustment component, which has a slide rail and A first positioning part of the rail, the adjustment assembly further includes a bone coupling part, the bone coupling part is slidably arranged on the slide rail, the first positioning part has a first joint part, and the first joint part can Slidably arranged on the bone plate, the adjustment assembly further includes an adjustment screw, one end of the adjustment screw is screwed on the first positioning member and can pass through the first positioning member and push against the bone joint, so that The osseointegration moves along the slide rail. The present invention has a smaller volume and lighter weight by virtue of the bone plate and the adjustment assembly that can be attached to the patient's limbs, and can achieve the effect of reducing the burden on the patient's daily life.

Description

technical field [0001] The present invention relates to a bone external fixator, in particular to a bone external fixator used in bone transport or bone lengthening. The present invention also relates to the adjustment assembly of the bone external fixator. Background technique [0002] For the treatment of patients with open fractures, after the treatment and debridement of the bone injury, some bone and soft tissue defects may occur at the bone injury, so the doctor will fix an existing external bone fixator 9 on the At the bone injury, the bone and soft tissue at the bone injury can be regenerated. [0003] Please refer to figure 1 As shown, the existing bone external fixator 9 includes several ring frames 91, and the several ring frames 91 are respectively arranged on the opposite ends of the bone injury by means of several bone nails 92 (hereinafter referred to as "broken bone B1" and "broken bone B2"), several support rods 93 are arranged between the two adjacent ri...
