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

The invention relates to a spinal pedicle fixation positioning guide system. The spinal pedicle fixation positioning guide system has a positioning guide device and a central management device which are communicably connected to each other through a sensor. The positioning guide device is connected with an inner fixed surgical opener, a wire tapping device and a nail holder, the central managementdevice acquires and records the instantaneous three-dimensional coordinates of the sensor, and the three-dimensional coordinates are calculated to obtain the correct open direction and open distance,an internal fixing mechanism is guided to operate according to the open direction and the open distance. Therefore, the spinal pedicle fixation positioning guide system of the present invention can quickly and accurately perform the spinal pedicle screw fixation operation without quickly and accurately guiding the internal fixation surgical instrument, and is simple in operation and convenient tocarry.

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...
