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

Embodiment Construction
[0050] In order to make the above-mentioned and other objects, features and advantages of the present invention more comprehensible, the preferred embodiments of the present invention are specifically cited below, together with the accompanying drawings, as follows:
[0051] The "bone transport" described in the present invention is often used in patients with large bone and soft tissue defect areas at the bone injury, and the doctor can fix the opposite ends of the bone injury (hereinafter referred to as "broken bone B1", "broken bone B2", such as Figure 4 , 5 shown), and obtain the bone at the end of the broken bone B1 facing the broken bone B2 (hereinafter referred to as "broken bone B3") as a bridge between the broken bone B1 and the broken bone B2, and gradually make the broken bone B3 from the broken bone Moving the broken bone B1 towards the broken bone B2 can regenerate the bones and soft tissues between the broken bone B1 and the broken bone B3, and between the brok...

Provided is a skeletal external fixator, applied in skeletal carrying or bone lengthening. The skeletal external fixator comprises a bone plate and an adjusting assembly. The bone plate comprises a plurality of bone positioning holes. The adjusting assembly is provided with a sliding rail and a first positioning piece arranged on the sliding rail. The adjusting assembly also comprises a bone connector. The bone connector is slidably arranged on the sliding rail. The first positioning piece is provided with a first joint part. The first joint part is sliabldy arranged on the bone plate. The adjusting assembly also comprises an adjusting screw rod. One end of the adjusting screw rod is screwed with the first positioning piece and passes through the first positioning piece and is abutted against the bone connector, so the bone connector moves along the sliding rail. The skeletal external fixator uses the bone plate and the adjusting assembly which can be covered on a patient limb. The fixator has relatively small volume and light weight, and achieves effects of reducing daily life burden of a patient.
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...
