Abstract

The invention discloses a positioning and marking device for X-ray adjustment of the lower spine, which includes a fixing device composed of a deck, an electric push rod, a fixing table, a stepping motor assembly, a rotating shaft and a connecting plate, and also includes a positioning frame and a first guide. Hole, A adjusting rod, second guide hole, B adjusting rod, collar, balloon, fixed cover, sliding sleeve, spring and brush. The existing examination bed is used as a complete set, and secondly, according to the patient's size, the electric push rod can be lifted and lowered to meet the needs of different patient sizes, and then the position can be determined with the existing X-ray irradiation, and then only need to move multiple groups of criss-cross adjustment rods to achieve different The positioning point is determined, and finally the balloon is pressed, that is, the brush touches the patient's skin downward, and then achieves the purpose of marking. In summary, the positioning of the spine is realized, saving time and effort, and optimizing the clinical operation.

Description

technical field [0001] The invention relates to a spine positioning instrument, in particular to a positioning marking device for adjusting the spine under X-ray coordination. Background technique [0002] Percutaneous pedicle screw internal fixation of vertebral body or percutaneous vertebroplasty requires precise preoperative positioning of the spine. Percutaneous vertebroplasty is used to treat osteoporotic compression fractures with the help of a two-way X-ray machine Under local anesthesia or general anesthesia, through the pedicle of the vertebral body, a balloon trocar with a certain inner diameter is inserted into the vertebral body, a contrast agent is injected into the balloon, and bone cement is injected after expansion to fill the fracture along the bone trabeculae to the entire vertebral body, so as to enhance the strength and hardness of the vertebral body, thereby reducing the pain of the patient. Although the vertebral body can be visualized by X-ray, CT, MRI...
