Embodiment Construction

[0026] In order to make the technical means, creative features, goals and effects of the present invention easy to understand, the following embodiments will specifically illustrate the spinal pedicle fixation and positioning guide system of the present invention in conjunction with the accompanying drawings.

[0027] Such as figure 1 As shown, a spinal pedicle fixation positioning and guiding system 100 is used for positioning and guiding the spinal pedicle fixation instrument, and the spinal pedicle fixation instrument includes a circuit opener T1, a tapper T3 and a nailer T2, characterized by comprising:

[0028] Such as figure 2 As shown, the positioning guide device 10 is used to connect the circuit breaker T1 , the tapping device T3 and the nailer T2 to the sensors correspondingly to form the circuit opening mechanism 14A, the tapping mechanism 12A and the nailing mechanism 13A. It includes an initial position correction plate 11 and an opener portion 14 , a nail sett...

Abstract

According to a kind of spinal pedicle fixation positioning guide system involved in the present invention, because it has the positioning guide device and the central management device that are connected to each other through sensor communication, the positioning guide device and the internal fixation surgery use opener, tapper and nail The central management device obtains and records the real-time three-dimensional coordinates of the sensor, and calculates the three-dimensional coordinates to obtain the correct open-circuit direction and open-circuit distance, and guides the internal fixation mechanism to operate based on the open-circuit direction and open-circuit distance. Therefore, The spinal pedicle fixation and positioning guide system of the present invention can quickly and accurately guide the internal fixation surgical instruments to quickly and accurately perform the spinal pedicle surgical fixation operation, and is simple to operate and easy to carry.

Description

technical field [0001] The invention belongs to the medical field, and in particular relates to a spinal pedicle fixation and positioning guide system. Background technique [0002] At present, the pedicle screw is one of the most widely used internal fixation devices in spinal surgery, and the successful and safe implantation of the pedicle screw is the key to ensure the success of the operation. [0003] The current pedicle internal fixation has some difficulties that plague the surgeon as follows: 1) because the outer diameter of the screw channel opening device is only about 1 / 3 of the outer diameter of the matching screw tapping device and nailing device. 2) Because of the patient's bone condition, the operating experience of the surgeon, and the unexpected situation during the operation, multiple open circuits often occur during the internal fixation of the pedicle, that is, there are multiple open circuits in one screw channel opening. out of the nail paths, and only...
