[0001] The invention relates to the field of medical instruments, and in particular to a kneecap drilling and fixing auxiliary device. Background Art
[0002] With the development of industrial technology, modern medical equipment technology has become more and more perfect. For patients with internal lesions of the kneecap, medical staff need to make holes in the kneecap before they can operate on the diseased tissue inside the bone. For patients with larger diseased tissues, multiple holes need to be made on the front and back of the kneecap. This operation requires the patient to turn over repeatedly. The patient's lower limbs have been anesthetized, so it is very difficult for the patient to turn over repeatedly, and the operation time will be prolonged during the turning process. The longer the operation time, the greater the patient's blood loss will be.
[0003] Secondly, a drill is used to operate the kneecap during the drilling process. The stability of a handheld drill is relatively poor, which will increase the wound area of the bone. In addition, if the drilling time is too long, the medical staff's arms will feel tired. Summary of the invention

The rubber block 603 reduces the pressure on the patient's side and increases the comfort of the patient's turning. When the medical staff needs to adjust the angle of the torsion ring 3 and the lying board 6, the medical staff inserts the foot into the step ring 801 and steps on it. When the brake shoe 8 and the outer wall of the torsion ring 3 are separated, the medical staff can adjust the angle. When the medical staff's foot is inserted and pulled out of the step ring 801, the brake shoe 8 is pushed up by the expansion spring 803 to lock the outer wall of the torsion ring 3. The rubber on the side wall of the brake shoe 8 The pad increases the friction with the outer wall of the torsion ring 3, and the rubber pad can be torn off and replaced with a new one regularly. The lifting drill at the end of the swing arm 702 and the pulling arm 704 can reach any position on the plane. The medical staff manually drags the drill 705 downward, and the return spring 707 can offset part of the gravity of the drill 707. The fatigue of the medical staff caused by holding the drill 707 for a long time will be relieved. The rubber rod 706 at the top of the drill 707 can be slightly bent, and the angle of the drill 707 in the vertical direction can also be fine-tuned.
