[0001] The utility model belongs to the technical field of medical auxiliary equipment, in particular to a mucosal fixator for oral surgery. Background Art

[0002] During oral surgery in the dentistry department, in order to expose the surgical field of the second and third molars on the buccal side of the mouth, which are closer to the pharyngeal tissue, the mucosa of the corner of the mouth needs to be pulled apart. The items commonly used in the existing dentistry department to help with traction are metal and plastic cheek retractors, which are relatively hard. The products on the market may have rough surfaces and sharp edges, and the force-bearing area is small. If the force is too great and the traction is prolonged, it will increase the risk of severe discomfort and injury, and may cause postoperative bleeding and swelling, affecting personal image and quality of life.

[0003] It can only pull the mucosa around the corners of the mouth, and cannot fully expose the molar area. At the same time, in order to ensure the accuracy of the operation, the assistant needs to help pull the doctor's vision all the time, and needs to maintain the same posture for a long time, and cannot always appear completely in the doctor's field of vision, which is very inconvenient.

[0004] CN105266917B discloses a gingival mucosal protective isolator for oral mandibular impacted third molar extraction surgery, the isolator comprising an elastic isolator body with an opening and a rubber isolation barrier in the shape of a "convex" character. The elastic isolator body comprises a mucosal support that is connected together and adapted to the buccal and lingual and distal mucosal incisions of the surgical incision, the two ends of the mucosal support opening are respectively provided with two symmetrical baffles, each baffle being provided with a pair of protrusions; the rubber isolation barrier is evenly and symmetrically provided with a number of small holes in two rows; the several small holes match the protrusions. However, when using this application, the doctor still needs to operate with at least one hand, and the fixation is not enhanced. Utility Model Content
