Abstract
The invention relates to an on-line electrical conductivity testing system for a portable pedicle screw implant navigator. A capacitive module consisting of a central electrode, a surrounding electrode and an insulating medium is arranged in a probe of the navigator; an embedded control system outputs pulse voltage to the probe of the navigator through a digital/analog (D/A) converter to charge the probe of the navigator; a voltage information processing module acquires voltage signals produced by discharge to a human medium when the probe of the navigator penetrates through the human medium; the voltage information processing module processes and converts the acquired voltage signals and then sends the converted voltage signals to a control module of the embedded system; the control module of the embedded system processes data and then outputs position signals to a voice module; and the voice module sends control commands. The system is used for navigating perforation of spinal surgery, prevents a pedicle screw from being placed mistakenly, prevents continuous weak current from injuring human body, and is convenient to carry.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, particularly a kind of pedicle screw is implanted the electrical conductivity Online Transaction Processing of portable navigation device.
Background technology
The LOCATION OF PEDICLE SCREW FIXATION therapy has a wide range of applications in spinal surgery, and can exactly the screw pedicle is screwed into vertebral body be pedicle of vertebral arch internal fixation operation key of success.Existing localization method is to adopt medical apparatus and instruments to detect, and more is experience and the feel that adopts the doctor, and it is not easy to carry when having outdoor use, and locatees inaccurate shortcoming.
Summary of the invention
The present invention be directed to the inaccurate by rule of thumb problem in location in the present LOCATION OF PEDICLE SCREW FIXATION therapy, proposed the electrical conductivity Online Transaction Processing that a kind of pedicle screw is implanted the portable navigation device, perforate is navigated to spinal operation, improves accuracy greatly.
Technical scheme of the present invention is: a kind of pedicle screw is implanted the electrical conductivity Online Transaction Processing of portable navigation device; Comprise omniselector probe, information of voltage processing module, embedded system control module, voice module, A/D modular converter; The probe of omniselector is made up of the model of an electric capacity contre electrode, surround electrode, dielectric; Embedded control system is popped one's head in to omniselector through the D/A converter voltage pulse output; To the probe charging of omniselector, the information of voltage processing module is gathered the probe of omniselector through the voltage signal of people's body medium to the generation of human body medium discharge, send the embedded system control module after the voltage signal treatment conversion of information of voltage processing module to collection; The outgoing position signal is to voice module after the embedded system control module deal with data, and voice module sends control command.
Said system is at first charged to electric capacity through the pulse voltage that D/A converter produces by embedded control system; The information of voltage processing module will be gathered the voltage of the electric current generation of process people body medium in the capacitor discharge process; The information of voltage processing module of embedded control system is amplified the voltage signal that collects earlier, after the Filtering Processing; Be input to A/D converter, conversion digital signal send embedded control system.
Beneficial effect of the present invention is: pedicle screw of the present invention is implanted the electrical conductivity Online Transaction Processing of portable navigation device, and perforate is navigated to spinal operation, avoids vertebra root screw misplace and the weak current that continues that human body is caused damage and is easy to carry.

The specific embodiment
Pedicle screw as shown in Figure 1 is implanted the structural representation of the electrical conductivity Online Transaction Processing of portable navigation device.Omniselector probe 1 is by the electric capacity of forming at the contre electrode and the insulating tape between the surround electrode of head.Embedded control system 3 provides the pulse voltage of omniselector probe work through D/A converter 5, promptly charges to electric capacity.After omniselector probe 1 got into human body, the load voltage that the electric current of capacitor discharge through tissue caused changed, and imports information of voltage processing module 2 into, and information of voltage processing module 2 converts information of voltage to embedded control system 3 tractable information.Because the electrical conductivity difference of vertebra and spinal fluid is big in the tissue; So be arranged in the capacitor discharge speed of spinal fluid when omniselector probe 2 faster than vertebra; Thereby embedded control system 3 can be confirmed the position of omniselector probe 1 according to the velocity of discharge; Voice module 4 is sent control command, and the position of prompting omniselector probe is in order to avoid cause damage.
Pedicle screw as shown in Figure 2 is implanted the information of voltage processing module sketch map of the electrical conductivity Online Transaction Processing of portable navigation device.As the probe 1 of scheming omniselector is by contre electrode 7, surround electrode 8, and dielectric 10 is formed the model of an electric capacity.Charged to electric capacity through the pulse voltage 6 that D/A converter 5 produces by embedded control system 3, information of voltage processing module 2 will be gathered the voltage of the electric current generation of process people body medium 9 in the capacitor discharge process.
Pedicle screw as shown in Figure 3 is implanted the omniselector sonde configuration sketch map of the electrical conductivity Online Transaction Processing of portable navigation device.The information of voltage that omniselector head 1 collects, it is little to have signal amplitude, and the characteristics that noise is big must be through circuit pre-processing module 12.Information of voltage to collecting amplifies, and the processing of filtering etc. is input to A/D converter, converts embedded control system 3 manageable digital signals to.
