Abstract

The invention discloses a three-dimensional positioning and guiding device for penetrating a vertebral pedicle through skin. The three-dimensional positioning and guiding device for penetrating the vertebral pedicle through the skin comprises a base, dip angle measuring devices and a measuring device supporting rod, wherein guiding grooves are arranged in length wise frame edges of the base, two dip angle measuring devices are matched on the measuring device supporting rod in a sliding mode, and an arc-shaped guiding groove is arranged in each dip angle measuring device. A bar-shaped hole is arranged in the measuring device supporting rod, a puncture needle guiding tube is in hinge joint with the dip angle measuring devices, and the puncture needle guiding tube penetrates through the bar-shaped hole. A guiding pin is arranged on the puncture needle guiding tube and is matched with the arc-shaped guiding grooves, marking needle fixing holes are arranged in the middle portion of the measuring device supporting rod, and two ends of the measuring device supporting rod are cylindrical segments. The measuring device supporting rod is matched with the guiding grooves in a sliding mode through sliding blocks, the cylindrical segments of the measuring device supporting rod extend out of the sliding blocks and are connected with a positioning rod, and the positioning rod is in the same plane with the measuring device supporting rod and the puncture needle guiding tube. The three-dimensional positioning and guiding device for penetrating the vertebral pedicle through the skin is capable of three-dimensional positioning and guiding and shortening the operation time, high in efficiency, accurate in guiding and capable of improving the achievement ratio of operation.

Description

technical field

[0001] The invention relates to a medical device, in particular to a three-dimensional positioning and guiding device for percutaneous pedicle puncture. Background technique

[0002] Due to the biomechanical advantages of three-column fixation, posterior pedicle screw fixation has been widely used in spinal surgery. The traditional surgical method requires extensive stripping of the paraspinal muscles, stretching the muscle tissue for a long time, large surgical trauma, excessive bleeding, postoperative paraspinal muscle denervation, scarring of muscle fibers, and long-term low back pain. Therefore, percutaneous pedicle screw technology has received more and more attention and developed rapidly. In 1984, French scholars pioneered percutaneous vertebroplasty because of its small trauma, quick onset and relatively few complications in osteoporotic compression fractures, vertebral metastatic tumors, and vertebral hemangiomas. Advantages, widely used in spine s...
