A kind of mandibular fracture external fixation bracket and fixation method thereof

Abstract

The invention discloses an external fixation bracket for mandibular fractures and a fixing method thereof. The fixator includes an external fixation rod assembly, an adjustment support assembly and a locking assembly. The external fixation rod assembly is provided with a through groove, and its lower end is provided with a Through holes, the adjustment support assembly includes an adjustment screw rod, a support assembly arranged on the adjustment screw rod, a first adjustment nut, a second adjustment nut and a first compression nut, and the support assembly includes a front end connected in sequence, a first support rod, a support sheet, the second support rod and the rear end, and the rod body passes through the first outer fixing rod, the first adjusting nut, the front end, the rear end, the second adjusting nut, the second outer fixing rod and the first compression nut in turn. In the present invention, the fixing bracket is provided with an adjustable support assembly, so that after the operation, the mandible is not only subjected to the opposite tension force of the first external fixation rod and the second external fixation rod, but also the upward support force of the support plate, It makes the damaged part fit better and improves the treatment effect.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an external fixation bracket for mandibular fractures and a fixing method thereof. Background technique [0002] At present, according to statistics, oral and maxillofacial trauma accounts for about 10% to 20% of systemic trauma. Trauma to human bones caused by traffic accidents or other accidents is common, and the number of patients with human maxillofacial bone fractures is on the rise. The treatment of fractures usually adopts open reduction and internal fixation, which is mainly manifested in first cutting open the soft tissue outside the bone and then using bone nails or steel plates, steel wires and other devices to perform internal bone fixation in the tissue to treat maxillofacial bone fractures. The following complications may occur: wound surface infection, retention of foreign bodies in the jaw, rejection of foreign bodies by the human body, especially interna...

Problems solved by technology

[0002] At present, according to statistics, oral and maxillofacial trauma accounts for about 10% to 20% of systemic trauma. Trauma to human bones caused by traffic accidents or other accidents is common, and the number of patients with human maxillofacial bone fractures is on the rise. The treatment of fractures usually adopts open reduction and internal fixation, which is mainly manifested in first cutting open the soft tissue outside the bone and then using bone nails or steel plates, steel wires and other devices to perform internal bone fixation in the tissue to treat maxillofacial bone fractures. The following complications may occur: wound surface infection, retention of foreign bodies in the jaw, human body’s rejection of foreign bodies, especially for children, internal fixation will affect the development of the child’s jaw in the future, etc.

[0003] However, internal fixation is widely used clinically, which not only has a negative psychological effect on patients, but also sometimes requires trauma to the patient again to remove the internal fixation after the fracture has recovered, which to a certain extent has caused secondary trauma to the patient. Trauma, which brings insurmountable difficulties to both medical staff and patients themselves;

[0004] Although the external fixator in the prior art can also reinforce the mandible with bolts, it does not support the lower end of the human mandible, resulting in a poor recovery effect on the injured part of the patient.
