Description

Oral cavity maxillofacial ossicle piece resetting means

Technical Field

The utility model relates to the field of medical auxiliary instruments, in particular to an oral cavity maxillofacial ossicle resetting device.

Background

The most common maxillofacial fracture is the orofacial ossicle, also known as mandibular condylar fracture. The condyle of the mandible participates in the formation of temporomandibular joints, is one of weak parts of the mandible, and can be fractured after being struck by direct or indirect external force, the condyle fracture of the mandible accounts for about 20% -30% of the fracture of the mandible, and if the fracture is not treated properly, complications such as ankylosis can occur. After the mandibular condyle fracture, the muscle attached to the broken end of the condyle contracts, so that the broken end of the mandibular ascending branch moves upwards, and if the fracture reduction fixing operation is not performed in time, sequelae such as maxillofacial deformity, ankylosis, occlusion function loss and the like are easily caused, thereby causing great harm to patients.

When the mouth and jaw facial ossicle resetting operation is performed on a patient, a medical worker needs to prop open the mouth of the patient through a surgical instrument all the time, so that the mouth and jaw facial ossicle resetting operation is convenient to perform, but the medical worker props open the mouth of the patient for a long time to cause fatigue, and the medical worker is not good in control, so that the problem that the mouth of the patient is easy to loosen after propping open the mouth is caused, the mouth and jaw facial ossicle resetting operation is affected, and the problem of secondary injury to the mouth and jaw facial ossicle of the patient is caused; and because the oral cavity environment is airtight, the light is not enough, can seriously influence medical workers' operation, reduces operation efficiency and success rate.
