Temporary mandible external fixed support applied in wartime or field environment and using method of external fixed support

Abstract

The invention belongs to the technical field of medical apparatuses, and in particular a temporary mandible external fixed support applied in wartime or field environment and a using method of the external fixed support. The external fixed support comprises a semicircular connecting rod, a binder clip and a T-shaped tool, wherein the back end of the connecting rod is inclined upwards; a fixed plate is arranged on the inner side face of the back end of the connecting rod; a grooved blind hole is each arranged in the upper and lower ends of the outer end face of the fixed plate; at the bottoms of the grooved blind holes, a grooved through hole is formed in the fixed plate; between the the two grooved blind holes, a clamping platform is arranged on the outer side face of the fixed plate; a second notch is arranged in the part, in correspondence to a first notch, of the lower end face of an outer nail; the lower end of a vertical rod is matched with a first rectangular blind hole; and a third rectangular blind hole, which is matched with a rectangular boss, is arranged in the lower end face of the vertical rod. The external fixed support has a purpose that problems of existing mandibleexternal fixed supports which, due to structure defects, are inconvenient in air duct management, not beneficial for carrying since a fixed bone nail can be screwed into a bone substance under the assistance of an electric drill or a hand drill and are troublesome to operate of suturing tongues of wounded persons via steel wire ropes or surgical sutures can be solved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a temporary external fixation bracket for the mandible in wartime or in the field and a method for using the same. Background technique [0002] Usually, oral and maxillofacial trauma accounts for about 10% to 20% of systemic trauma. Human bone trauma caused by traffic accidents or other accidents is common. Among them, the number of patients with human maxillofacial bone fractures is on the rise. The treatment usually adopts open reduction and internal fixation, which is mainly manifested in the treatment of maxillofacial bone fractures by cutting the peripheral tissue of the bone first and then using bone nails or other devices to internally fixate the bone tissue. The following complications may occur in this operation: Trauma Facial infection, retention of foreign bodies in the jaw, human body's rejection of foreign bodies, especially internal fixation for...
