Description

Technical Field

[0001] The utility model relates to the technical field of oral surgery instruments, in particular to a cutting device for oral tissue. Background Art

[0002] Cutting of oral tissue is the process in which dentists use specific tools to cut, repair or clean oral tissue during oral surgery or treatment. Cutting devices are usually used in current oral surgery to accurately cut oral tissue, including teeth, gums, etc., to ensure the accuracy and efficiency of the surgical operation, while reducing damage to surrounding healthy tissues and reducing trauma during the operation.

[0003] When using a traditional oral tissue cutting device, the part of the tissue that needs to be cut is first accurately located to clarify the surgical goal. The dentist selects a suitable oral tissue cutting device according to the condition and treatment needs, and finally cuts the oral tissue. However, when the traditional device aims the cutting knife at the oral tissue that needs to be cut, it is difficult to control the distance between the cutting knife and the oral tissue due to the relatively small space inside the oral cavity, which may accidentally damage the surrounding healthy tissue, causing unnecessary trauma and complications. In addition, a cutting distance that is too close or too far may result in poor surgical results, affect the accuracy and completeness of the treatment, and thus reduce the success rate of the operation. At the same time, it will cause the operation to last longer, increase the patient's discomfort and fatigue during the operation. Summary of the invention
