[0002] Oral and maxillofacial surgery is a discipline that focuses on surgical treatment and studies the prevention and treatment of oral organs (teeth, alveolar bones, lips, cheeks, tongue, palate, pharynx, etc.), facial soft tissues, maxillofacial bones (maxilla, mandible, zygomatic bone, etc.), temporomandibular joint, salivary glands, and certain neck-related diseases. During the diagnosis and treatment of oral organs, surgical retractors are used to open the patient's mouth to facilitate observation of internal details.

[0003] Medical staff engaged in oral and maxillofacial surgery found in their work that due to differences in the shape and size of patients' mouths, fixed surgical retractors have poor adaptability during use, resulting in the surgical retractors being unable to fit the fixed parts and poor applicability, leading to poor patient comfort during surgery and the risk of unhooking. For this reason, we propose a deformable maxillofacial retractor. Utility Model Content
