Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a retractor for oral and maxillofacial surgery. Background technique [0002] Oral and maxillofacial surgery is mainly based on surgical treatment. It studies oral organs, facial soft tissues, maxillofacial bones, temporomandibular joints, salivary glands, and some related diseases in the neck. If a disease occurs in the oral and maxillofacial region, if it is not treated in time and correctly , the consequences are more serious, and usually need to use the spreader to open the patient's oral cavity when treating oral and maxillofacial surgery, so that the medical staff can perform the operation conveniently. [0003] The existing defects of the retractor for oral and maxillofacial surgery are: [0004] 1. It is inconvenient to grasp the spacing of the mouth opening, which may cause secondary damage to the patient due to excessive opening spacing, which reduces the conve...
