Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a mandibular supporting device. Background Art

[0002] During intraoral surgery, the oral cavity needs to be stretched open to facilitate the doctor's operation. The problem in the prior art is that the retractor has poor adaptability, and the position and shape of the lower jaw of each patient are different, so it is necessary to select a retractor that is adapted to the patient, which is a cumbersome process.

[0003] However, the problem with some well-adapted retractors is that after the patient's mouth is stretched open, the angle of the patient's mouth toward the doctor cannot be changed by turning the patient's head. For example, a mandibular support device for anesthesia clinic with authorization number CN214805515 U has such a problem.

[0004] If the patient's head always remains in one position, there will be many blind spots inside the patient's mouth for the doctor. If the patient's own position cannot be adjusted, the doctor will need to adjust his or her own body position in order to see other parts of the patient's mouth and operate. In this process, the doctor's posture is obviously not upright and he or she needs to lean forward or bend further, which will greatly increase the doctor's fatigue level and is not conducive to the continuation of the operation.
