Description

TECHNICAL FIELD

[0001] The utility model relates to dental clinical application technical field, concretely is rubber dam cloth punching positioning device. BACKGROUND

[0002] Oral rubber dam is a rubber cloth that isolates teeth, so that saliva in the mouth does not flow into the dental operating area. Since the filling material of dentistry may cause treatment failure when being contaminated by saliva or blood, the isolation of liquid is very important.

[0003] The rubber dam also separates the water sprayed by the dental instruments from entering the patient's mouth, so the suction device does not need to be inserted into the bottom of the patient's mouth, causing discomfort and foreign body sensation leading to vomiting. The use of rubber dam can also protect the soft tissues of the mouth, including lips, cheeks, tongue, etc. from being injured by dental instruments. In addition, the rubber dam can prevent small instruments from falling into the mouth and being accidentally swallowed into the esophagus or trachea, and reduce the cross infection between patients and doctors.

[0004] In the actual operation of the rubber dam, the rubber cloth needs to be punched, before which the rubber cloth needs to be pulled apart manually, then a punching plate is used to mark on the rubber cloth, and finally a punching device is used for punching. In this process, the step of pulling apart the rubber cloth often needs two medical staff to perform (see oral assistant practitioner examination), resulting in a waste of manpower and low efficiency. In addition, when the rubber dam is pulled apart by the pulling tool, since the rubber dam has ductility, uneven pulling may occur, thereby affecting the punching precision. UTILITY MODEL CONTENTS
