The invention provides a special draw hook for forming a
chin, which is used for protecting
chin nerves in a
chin forming technology and belongs to the technical field of clinical
medicine. The chin forming technology comprises a plurality of abnormal surgeries including correction of chin overdevelopment and
maldevelopment, and chin part deflection and the like which involve three-dimensional directions including front and back, up and down, and left and right of a chin part. The special draw hook for forming the chin is composed of a draw hook body part and a draw hook
handle; in the
surgery, the special draw hook for forming the chin is arranged on an
osteotomy line of the chin part and is basically parallel to the
osteotomy line; the front end of the draw hook is arranged on a
bone surface under the chin nerves and the draw hook
handle is located at a mouth corner region at the opposite side; a straight-line-shaped gap is remained reserved in the middle of the draw hook body part, and the chin forming
osteotomy line can be exposed from the gap region; an osteotomy device is put into the gap region to saw back and forth so that the chin forming
surgery is finished. The special draw hook for forming the chin is divided into left and right parts which are applied when surgeries at the two sides of the chin part are done. By adopting the special draw hook for forming the chin, a better
surgery view field is provided for the chin forming technology, the protection on the chin nerves and mucosal tissues of mouth corners is facilitated, the surgery efficiency is improved and the surgery risks are reduced at the same time.
