Description

Technical Field

[0001] The invention relates to the technical field of oral dilation in stomatology, and in particular to an oral dilation tool for stomatology surgery and a use method thereof. Background Art

[0002] In medical dentistry, patients are required to open their mouths when treating oral diseases. However, sometimes the patient's mouth closes spontaneously during surgery, causing damage to the patient's mouth. The patient's mouth needs to be opened with an oral expansion tool to avoid oral closure during surgery, which affects the treatment.

[0003] However, the existing oral opening tools cannot adjust the opening angle according to the patient's condition during use, thereby affecting the patient's comfort.

[0004] In order to solve the above-mentioned defects, in the prior art, a Chinese patent with publication number CN221866095U discloses an oral examination auxiliary dilation tool, comprising a base plate and two supporting legs fixedly arranged on the bottom surface of the base plate, a lifting mechanism and a dilation mechanism are arranged above the base plate; the lifting mechanism is located below the dilation mechanism; the dilation mechanism comprises a dilation part and an adjustment part, and the technical effect is that the dilation mechanism can be provided to dilate the patient during oral examination, making it easier for the patient to perform oral examination, and the adjustment part can be provided to adjust the height of the two dilation plates according to the patient's own situation during the dilation process, making the patient more comfortable during oral examination, and the insertion rod, the rotating rod, the clamping plate, the pull ring and the first spring can adjust the angle of the two dilation plates, so that the patient's mouth can be supported left and right, so that it can be adjusted when performing different oral examinations.

[0005] Moreover, in the prior art, a Chinese patent with publication number CN216777248U discloses an oral stretcher, comprising a base and a U-shaped frame, wherein the base is horizontally arranged, and the top surface of the base is provided with the U-shaped frame vertically arranged in the longitudinal direction, and the distance between the two rows of tooth bite assemblies can be adjusted and locked respectively by means of a stud vertically sliding along an adjustment groove and tightening a locking nut to be pressed against the side of the U-shaped frame, so that the patient can stretch the patient's mouth and adjust the degree of stretching after biting the tooth bite groove, replacing the operation mode of the patient biting a stick, and can adjust the degree of oral stretching of the patient according to the individual, which is not easy to cause discomfort to the personnel, and improves the general use range of the device; the upper and lower tooth bite assemblies can be raised and lowered separately, and then can be respectively adapted to the use of patients with difficult upper and lower jaw movements, further improving the general use range of the device.
