Description

TECHNICAL FIELD

[0001] The utility model relates to medical equipment technical field, more specifically, especially relates to a preoperative positioning plate for spine surgery. BACKGROUND

[0002] Spine minimally invasive surgery is increasingly dominant, such as Mistlif surgery, endoscopic interbody fusion, percutaneous pedicle screw implantation of spinal fracture and spinal orthopedic surgery and percutaneous vertebroplasty, etc., these operations all need to be carried out under the C-arm X-ray perspective in the operating room after the patient is anesthetized, in order to accurately find the target pedicle shadow, then draw a line on the corresponding skin as a puncture point, and perform surgical operation. In addition, unilateral double channel endoscopic technique (UBE technique) of spine, endoscopic technique through interlamina approach, etc. also need to be carried out under the C-arm X-ray perspective after the patient is anesthetized, in order to determine the skin incision position.

[0003] At present, many doctors use kirschner wire or small metal objects for positioning, which is relatively primitive and increases the number of perspectives; or some hospitals use standard grid-shaped metal positioning plate or grid silicone material for positioning, which is fast, but because there are many grid lines, they block part of the spine marker points, so that the image after perspective is not simple and clear, especially for obese patients, upper and middle thoracic vertebrae or patients with severe spinal degeneration. Many perspective metal lines and the already unclear perspective image are mixed together, and the doctor has difficulty in identifying the target position, which brings difficulty to the doctor in accurate positioning. In addition, because the human spine has normal physiological curvature, the tilt angle of the C-arm needs to be adjusted during intraoperative perspective, in order to ensure accurate positioning of the target vertebrae. If there is no tilt angle of the C-arm, it is easy to cause a large difference between the skin incision after positioning and the actual skin puncture point. But if the tilt of the C-arm is adjusted, and the metal grid plate is not well attached to the skin, the grid lines in the perspective also have large deviations. Therefore, the current clinical use of grid-shaped metal positioning or grid-shaped silicone positioning cannot meet the following two points at the same time: 1. accurate positioning and reducing the interference with the perspective of the spinal vertebrae marker; 2. good adhesion to the skin to reduce perspective and positioning errors when adjusting the tilt angle of the C-arm.
