Oral and maxillofacial surgical distractor

Abstract

The invention discloses an oral and maxillofacial surgical distractor, which includes a dental distraction device. The dental distraction device is movably connected with one end of a short rod. The other end of the short rod and a first connecting rod are fixedly connected through an undercut area of a buckle device. One side of the first connecting rod is welded with one end of a lip-cheek expansion device, one side of which is provided with a plastic cushion. The other end of the lip-cheek expansion device is welded with a second connecting rod. The second connecting rod and a first supporting adjustable lever are welded. One end of the first supporting adjustable lever is welded with one end of a second supporting adjustable lever. The other end of the first supporting adjustable leveris vertically welded with one end of a first spring lever. The other end of the second supporting adjustable lever is welded with one end of a second spring lever, the other end of which is welded with the other end of the first spring lever. The bottom ends of the second supporting adjustable lever and the first spring lever are equipped with a same dental distraction device and a same lip-cheekexpansion device as the top end. The oral and maxillofacial surgical distractor of the invention is simple to operate and has a good fixing effect.

Description

technical field [0001] The invention relates to the technical field of oral surgery, in particular to a retractor for oral and maxillofacial surgery. Background technique [0002] Oral and maxillofacial surgery (oral and maxillofacial surgery) is a surgical treatment-based study of oral organs (teeth, alveolar bone, lips, cheeks, tongue, palate, pharynx, etc.), facial soft tissues, and maxillofacial bones ( Maxilla, mandible, zygoma, etc.), temporomandibular joint, salivary glands, and the prevention and treatment of some related neck diseases.

It is precisely because of the formation and participation of oral and maxillofacial surgery that Chinese dentistry has developed into stomatology. It should be said that oral and maxillofacial surgery has dual attributes. On the one hand, in order to prevent and treat oral and maxillofacial surgery Oral and maxillofacial sur...

AI Technical Summary

Problems solved by technology

[0003] Traditional oral and maxillofacial retractors cannot accurately adjust the distance of the retracted occlusal surface, and cannot adapt to individual differences of patients. After retraction, the card slot is easy to slip off from the occlusal surface, which affects the accuracy of retraction, and patients often feel uncomfortable

The existing retractors are either large in size, and a large handle remains outside the patient's mouth after retraction, causing psychological burden to the patient; or they are single-sided retractors, which are easy to damage the teeth and mucosal tissues in the mouth if they are not fixed firmly.

After opening the gap, the assistant needs to open the lip and buccal tissue to expose the surgical field. The assistant is prone to fatigue and the operation efficiency is low.
