Mandible reduction device

Abstract

The invention relates to a mandible reduction device. The device comprises a fracture connecting part matched with the radian of the lower edge of a mandible, a bone-setting part arranged at the upperend of the fracture connecting part and matched with the radian of a labiobuccal sulcus, and traction parts arranged on the upper portion of the connecting part and on two sides of the bone-setting part. Positioning holes are formed in the connecting part, mounting holes are formed in the bone-setting part, traction holes are formed in the end, away from the connecting part, of the traction parts, the bone-setting part is arranged in the middle of the connecting part, and the connecting part, the traction parts and the bone-setting part are all connected to the mandible through traction nails. The mandible reduction device achieves fracture reduction and effective fixation, recovers the anatomical structure of the mandible to the maximum extent, promotes fracture healing, improves clinical symptoms of a patient, and improves the clinical treatment effect.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a mandible reduction device. Background technique [0002] Mandibular fracture is a common disease in oral and maxillofacial surgery, and it is also one of the main forms of fracture. Clinically, surgical treatment is mainly used to reduce and heal the broken end of the fracture and restore the anatomical structure, so that the relationship between masticatory function and bite can be restored to normal, and Restoring the shape of the face to protect the physical and mental health of patients and improve their quality of life. Due to the special anatomical structure of the jaw bone, which participates in various functions of oral chewing, swallowing, pronunciation and breathing, its physiological requirements are relatively high, and the blood supply is rich in this place, and the fracture ends heal quickly. If there is no good reduction and fixation in the i...

AI Technical Summary

Problems solved by technology

Although it can meet the requirements of reduction treatment, it has the following disadvantages in the clinical application process: the placement of the dental arch splint and the ligation of the steel wire are relatively complicated, and the periodontal tissue will inevitably be damaged; the hook end and a large number of steel wires carried by the dental arch splint are exposed to the oral cavity. Internally, patients have obvious foreign body sensation, poor comfort, and are not conducive to oral hygiene and cleaning; this operation takes a long time and is difficult, especially for patients with deep coverage, crowded dentition, and limited mouth opening , the clinical difficulty is relatively large, and some patients even find it difficult to perform the procedure to meet the clinical requirements; the stability is poor, and the fracture site will be in a state of micro-motion for a long time to stimulate cartilage osteogenesis, which will adversely affect the healing of the fracture and the recovery of the bite relationship; It cannot provide enough support, and it is prone to displacement or torsion due to the influence of surrounding muscle traction or mandibular movement, which affects the growth of capillaries at the stump end and the differentiation of bone cells, and delays healing. Temporomandibular joint immobilization is required during the overall treatment. The patient's eating, speech, and oral hygiene are all affected, which not only interferes with the patient's life and work, but also seriously affects the patient's intake of nutrients, resulting in osteoporosis and reduced healing ability. Long-term restriction of joint movement can also cause muscle pain. Atrophy or even degenerative joint disease

[0004] The mandible is the only large bone that can move in the maxillofacial region and participates in the formation of the temporomandibular joint. Therefore, the masticatory function is greatly affected after injury. At present, there is a lack of a fracture fixation and reduction device with a wide range of applications and low manufacturing cost for related treatment.
