Embodiment 1
[0044] Such as figure 1 As shown, a pedicle screw implantation method S100 is used to accurately position and guide the spinal pedicle fixation instrument through an external device to complete the implantation of the pedicle screw. The spinal pedicle fixation instrument includes Open-circuit components, tap components, and nail-on components. Include the following steps:
[0045] Step S1: obtain the instant coordinates of the open circuit assembly, the thread tapping assembly and the nail assembly; include the following sub-steps:
[0046] Step S1-1: connecting the open-circuit assembly provided with the sensor, the tapping assembly provided with the sensor, and the nailing assembly provided with the sensor with the external device respectively;
[0047] Step S1-2: the external device obtains the instant coordinates of the sensor through the communication connection, and uses the instant coordinates of the sensor as the instant coordinates of the corresponding open circuit ...
Embodiment 2
[0080] Such as Figure 4 As shown, a pedicle screw implantation method T100 is used to accurately position and guide the spinal pedicle fixation instrument through an external device to complete the implantation of the pedicle screw. The spinal pedicle fixation instrument includes The open circuit assembly, the screw tapping assembly and the nailing assembly, the structures and functions of the opening assembly, the screw tapping assembly and the nailing assembly are all the same as those in the first embodiment.
[0081] Such as figure 2 As shown, the external device is respectively connected to the nail assembly, the screw tapping assembly and the nail assembly, including a communication unit 202, a data calling unit 206, a data computing unit 209, a data adding unit 213, a data updating unit 214, and a data generating unit 207 , data deletion part 208, data storage part 210, data judgment part 211, voice prompt part 204, picture storage part 205, picture display part 203 ...

Abstract
The invention relates to a method for implanting a pedicle screw. An external device acquires instant coordinates of a passage opening assembly, instant coordinates of a screw tapping assembly and instant coordinates of a screw mounting assembly separately, wherein the passage opening assembly, the screw tapping assembly and the screw mounting assembly are used as a spinal pedicle fixation device;the passage opening assembly is operated to obtain a passage opening hole channel; the external device acquires coordinates of a passage opening starting point and coordinates of a passage opening ending point; the passage opening direction and the passage opening distance are obtained according to the coordinates of the passage opening starting point and the coordinates of the passage opening ending point; then the screw tapping assembly and the screw mounting assembly are quickly and accurately guided according to the passage opening direction and the passage opening distance to complete implanting of the pedicle screw; in this way, the method for implanting the pedicle screw can accurately guide the operation of the screw tapping assembly and the screw mounting assembly and has the advantages of being high in accuracy and easy to operate and grasp compared with previous spinal pedicle screw implanting methods.
Description
technical field [0001] The invention belongs to the medical field, and in particular relates to a method for implanting a pedicle screw. Background technique [0002] At present, pedicle screw is one of the most widely used pedicle instruments in spinal surgery, and the successful and safe implantation of pedicle screw is the key to ensure the success of the operation. Previous operations relied on the surgeon's subjective tactile feedback and empirical judgment to distinguish the less resistant cancellous bone from the harder cortical bone surrounding the pedicle to avoid improper screw placement. Therefore, occasional deviations in screw placement are unavoidable. The traditional screw placement method represented by freehand screw implantation of the pedicle commonly used in the past is still affected by many factors, such as scoliosis, variation, osteoporosis and multiple operations of the patient's anatomical site, which can all affect the pedicle. Accurate placement o...
