Abstract

The invention discloses a tissue retractor used in an oral surgery, and relates to the technical field of medical instruments. The tissue retractor comprises a rectangular cylinder, wherein a fixing block is fixedly connected in the rectangular cylinder, and first small electric push rods are fixedly connected to the left side and the right side of the fixing block. According to the tissue retractor used in the oral surgery, two lower-layer protection pads are in contact with lower-row teeth of a patient, supporting rods, L-shaped rods and upper U-shaped supporting plates automatically move upwards by the aid of elastic force of springs, two upper-layer protection pads are automatically in contact with upper-row teeth of the patient, rotating screw rods are forwardly rotated to be abuttedto the supporting rods, so that the supporting rods are fixed, the supporting rods, the L-shaped rods and the upper U-shaped supporting plates do not descend, the oral cavity of the patient is opened,the tissue retractor is simple to operate and convenient to use, use requirements of a user are met, and the device can be adjusted according to the sizes of different oral cavities and has universalapplicability.

Description

Technical field [0001] The invention relates to the technical field of medical devices, in particular to a tissue retractor used in oral surgery. Background technique [0002] Dentistry is one of the classification of medical disciplines. It is generally integrated into the department of dentistry in large hospitals. Dentistry mainly treats teeth and periodontal-related diseases. When medical staff perform oral surgery on patients, they need to use a retractor to retract the patient’s wound. Open in order to expose a better view of the patient for surgery. [0003] When performing surgery on a patient, the patient needs to fully open the oral cavity so that the medical staff can perform the operation on the patient. Although the existing retractor has the function of opening the patient’s oral cavity, it cannot be adjusted according to the size of the patient’s oral cavity. Adjust the distance between the upper U-shaped pallet and the lower U-shaped pallet. If the distance between...
