Embodiment Construction

[0023] The present invention will be described in further detail below through the embodiments and accompanying drawings.

[0024] Such as figure 1 and figure 2 As shown, the visual pedicle screw implantation auxiliary system includes an open-circuit cone 1, which includes a cone 11. The front end of the cone 11 is fixedly connected with a cone blade 12. The inside of the cone 11 is hollow, and an endoscope is provided inside it. The mirror 3 and the endoscope 3 are arranged near the tapered edge 12, and the tapered edge 12 is made of a rigid light-transmitting material. For the convenience of medical staff, the tail of the cone 11 is provided with a handle 13 for medical staff to operate.

[0025] In order to ensure the service life of the cone blade 12 and the medical staff can clearly watch the image of the front end of the open-circuit cone 1, the cone blade 12 is made of diamond or transparent ceramics with wear resistance, high hardness and good light transmission. T...

Abstract

The invention discloses a visualized pedicle screw implanting auxiliary system, and relates to the technical field of pedicle screw implanting. The visualized pedicle screw implanting auxiliary system comprises an open cone and a display device, wherein the open cone comprises a cone body, the tail part of the cone body is provided with a handle for a medical person to hold, the cone body is of a hollow structure, an endoscope is arranged in the cone body, the front end of the cone body is provided with a cone blade which is made of rigid transparent material, the endoscope is arranged near the cone blade, and the display device is connected with the endoscope, and is movably arranged at the end part of the handle. The visualized pedicle screw implanting auxiliary system has the advantages that the visualizing of the pedicle screw opening process is realized, the breakthrough rate of the pedicle and the unacceptable rate of screw positions are reduced, the injury to surrounding important tissues because of breakthrough of bones is avoided, and the success rate of pedicle screw implanting operations is greatly improved.

Description

technical field [0001] The invention relates to the technical field of pedicle screw implantation, in particular to a visual aid system for pedicle screw implantation. Background technique [0002] Currently, the use of pedicle screws is the standard treatment for spinal stabilization reconstruction. The pedicle screw internal fixation system can effectively complete the three-column fixation of the spine, meet the biomechanical requirements of spinal fixation, and greatly improve the treatment effect of spinal diseases. [0003] Although pedicle screws have revolutionized the treatment of spinal trauma, their implantation procedure still carries high risks. Because the diameter of the spinal pedicle is limited, and it is adjacent to many important tissues. For example, the cervical pedicle is adjacent to the spinal cord and the vertebral artery on the outside. There are nerve roots across the upper and lower sides. The thoracic pedicle is adjacent to the spinal cord, nerve...
