A tissue retracting device used in oral surgery

Abstract

The invention discloses a tissue retracting device used in oral surgery, which relates to the technical field of medical devices, and comprises a rectangular cylinder, a fixed block is fixedly connected inside the rectangular cylinder, and both left and right sides of the fixed block are fixedly connected with A small electric push rod one. The tissue retraction device used in oral surgery, through the two lower protective pads in contact with the patient's lower teeth, relying on the elastic force of the spring to automatically move the support rod, L-shaped rod and upper U-shaped supporting plate, and make the upper layer The two protective pads are automatically in contact with the patient's upper row of teeth. By turning the rotating screw in the forward direction, the rotating screw is pressed against the support rod to fix the support rod, so that the support rod, the L-shaped rod and the upper U-shaped support plate are no longer lowered. Furthermore, the patient's oral cavity is stretched, the operation is simple, the use is convenient, and the use requirement of the user is met, and the device can be adjusted according to the size of different oral cavity, and has universal applicability.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a tissue retracting device used in oral surgery. Background technique [0002] Dentistry, one of the classifications of medical disciplines, is generally incorporated into the Department of Stomatology in large hospitals. Dentistry mainly treats diseases related to teeth and periodontium. During the oral surgery on patients, the medical staff need to use retractors to retract the patient’s wounds. Open, in order to expose a better field of vision for surgery on patients. [0003] When performing an operation on a patient, the patient needs to fully open the mouth so that the medical staff can operate on the patient. Although the existing retractors have the function of opening the patient's mouth, they cannot be adjusted according to the size of the mouth of different patients. Adjust the distance between the upper U-shaped support and the lower U-shaped support. If ...
