Percutaneous vertebral pedicle positioner

Abstract

The invention relates to percutaneous vertebral pedicle technology, in particular to a percutaneous vertebral pedicle positioner, which comprises a plurality of cross bars and a plurality of vertical bars, wherein the cross bars and the vertical bars are in cross connection to form a latticed plate; positioning holes are respectively arranged in a plurality of cross parts of the plate; and each cross bar and vertical bar are respectively made of high temperature resistant flexible metal materials. The percutaneous vertebral pedicle positioner utilizes the high temperature resistant flexible metal materials to make the latticed plate, and meanwhile meets the positioning requirements of ortho positions and side positions. The percutaneous vertebral pedicle positioner only adopts the cross bars and the vertical bars to make the positioner, and not only is the structure novel and simple, but also the cost is lower. The positioning holes with various shapes are arranged in the cross parts of the plate, so that the position of a vertebral pedicle inlet can be correctly recognized during positioning.

Description

technical field [0001] The invention relates to percutaneous pedicle technology, such as percutaneous pedicle screw placement, percutaneous vertebroplasty, percutaneous pedicle lesion biopsy, etc., specifically a percutaneous pedicle defined as device. Background technique [0002] Percutaneous pedicle technology refers to accurately inserting instruments into the pedicle through a small incision in the skin under the premise of minimally invasiveness. To accurately insert the instrument, the entrance position of the pedicle must first be accurately determined, which is Physicians are required to accurately position the skin before making small incisions. At present, there is no positioning tool that can allow doctors to accurately position and save valuable operation time. The traditional positioning method is that the doctor uses Kirschner wires to cross and fix on the skin, and then uses C-arm fluoroscopy to determine the position of the entrance of the pedicle in the a...

AI Technical Summary

Problems solved by technology

The traditional positioning method is that the doctor uses Kirschner wires to cross and fix on the skin, and then uses C-arm fluoroscopy to determine the position of the entrance of the pedicle in the anterior position, but this method often needs to repeatedly move the Kirschner wires; Fix the Kirschner wire obliquely on the side of the body, and then perform fluoroscopy, but it is also necessary to move the position of the Kirschner wire repeatedly, and the distance between the Kirschner wire and the skin is relatively large. Slight changes in the angle of the vertebral body, resulting in a large change in the positioning of the vertebral body, resulting in positioning errors

Repeated movement of the Kirschner wire often results in increased operation time and increased X-ray radiation exposure to the patient, which will increase hospitalization costs and increase the risk of teratogenicity
