Description
Technical Field
The utility model belongs to medical equipment, and particularly discloses a novel mandible titanium plate.
Background
The mandible is positioned at the lower part of the face, is arched, encloses the front wall and the side wall of the oral cavity, and is the only movable skeleton of the face. The horizontal part is mandible, the vertical part is mandible branch, the surface layer is compact bone, the inner part is spongy bone, and the temporomandibular joint is composed with temporomandibular joint concave. The mandible is divided into an inner face, an outer face and an upper edge and a lower edge. The mandibular branch is divided into two sides, four edges and two protrusions. The mandible branch articulates with the temporal bone. The joint is very flexible and can perform a variety of actions including chewing actions. The mandible has denser bone mass and poor blood supply, and is mainly supplied with blood from the artery branch of the bone surface mucoperiosteum as well as the blood supply of the lower alveolar artery. In recent years, maxillofacial fractures tend to rise year by year, the damage degree is increased, and the injury is complicated. The mandible is located in the exposed part of the human body, and the incidence of fracture is the first place of maxillofacial fracture. According to literature statistics, the incidence rate of the mandibular fracture accounts for 25% -28% of maxillofacial injuries, and accounts for 55% -72% of maxillofacial fractures. Mandibular fracture is well developed in young men, most chin-side fracture is combined with more face-to-face fracture, and in recent years, solid internal fixation is a better means of treatment due to car accidents. With technological advances, one common approach to current treatment is to use titanium plates and screws to fix bone. At present, the mandible titanium plate is of a single-row screw structure and is poor in stability. And if stability is to be increased, more titanium plates are implanted. This not only is the doctor cumbersome to operate and time consuming, but also makes the situation of the titanium plate implantation surgery more complex. Accordingly, there is a need to provide a new mandibular titanium plate to address these problems.
