The invention discloses an operation drag hook for the alveolar surgery department and a using method thereof.The operation drag hook comprises a shell, a first gear and a second gear are rotationally connected into the shell, sliding holes are formed in the first gear and the second gear, and rotating shafts are slidably arranged in the sliding holes; a first sliding groove is formed in the first gear, a second sliding groove and a wide groove are formed in the second gear, and the first sliding groove, the wide groove and the second sliding groove all communicate with the sliding hole; the rotating shaft is connected with a first sliding key and a second sliding key, the first sliding key is arranged in the first sliding groove in a sliding mode, the second sliding key is arranged in the second sliding groove in a sliding mode, and the second sliding key is rotatably arranged in the wide groove; the shell is slidably connected with a second rack and a first rack, the first rack is meshed with the first gear, the second rack is meshed with the second gear, and the other end of the first rack and the other end of the second rack are connected with independently-arranged drag hooks respectively. When the retractor is used, the retractor bodies can be controlled conveniently, and therefore the operation efficiency is effectively improved.
Description
technical field [0001] The invention relates to the technical field of alveolar surgery, in particular to a surgical retractor for alveolar surgery and a method for using the same. Background technique [0002] With the continuous improvement of people's living standards, periodontal diseases also follow. Today's people have broken the old thinking of the past, taboo diseases and avoid doctors, gradually enhance their health awareness, and pay more and more attention to periodontal diseases. In flap surgery, especially in periodontal surgery, the retractor for flap surgery is essential. [0003] However, during the operation, it is difficult for the surgeon to operate the existing surgical retractor by himself. The existing retractor is inconvenient to be adjusted independently, but requires an assistant to operate, which brings a lot of inconvenience to the operation. For several retractors, it is inconvenient to adjust and fix them individually, which greatly affects the ...
