Description
Technical field
The invention belongs to medical instruments field, be specifically related to a kind of spinal operation perforate and navigate detection system.
Background technology
Often need pedicle screw to be fixed treatment in spinal surgery, wherein pedicle screw fixation system in treatment method is most widely used in spinal surgery, has effectively promoted the development of spinal surgery.Can the key of pedicle internal fixation operation success or failure exactly screw pedicle is screwed into vertebral body.In prior art, the implantation of pedicle screw is more still experience by doctor and feel, and this mode screw misplace rate is high, may cause spinal cord and neural damage, thus cause patient to paralyse or functional disorder.
In order to improve the success rate of screw placement, existing localization method adopts medical apparatus and instruments to detect, and as x-ray, ct fluoroscopy in art, not only amount of radiation is large, equipment is huge for these equipment, cost is higher; And spinal cord monitoring system needs the training relevant speciality talent, high to the requirement of doctor; Then adopt electromyogram to carry out the detection of pedicle screw implantation, but electromyogram wave noise is comparatively large, during the perforation of pedicle screw implantation, signal is not obvious, easily mixes.Therefore, the research about pedicle screw fixation is the problem received much concern always.
Summary of the invention
The present invention carries out for solving the problem, and by providing a kind of spinal operation perforate to navigate detection system, increases the success rate of screw placement in spinal operation.
Present invention employs following technical scheme:
Spinal operation perforate provided by the invention is navigated detection system, has such feature, has: exciting current module, for generation of stimulating current; Current processing module, and exciting current model calling, for filtering stimulating current, make the intensity of stimulating current be within the scope of 1 ~ 15mA; Electricity irritation probe, and current processing model calling, for stimulating current being imported the health of patient, and carry out electricity irritation to contact site; Myograph detection module, comprises at least one piece of myograph sensor, moves signal for collecting the flesh produced after contact site is subject to electricity irritation; And detection display module, detect for intensity flesh being moved to signal, the contact site when intensity allowing doctor flesh be moved signal is zero is defined as position of opening.
Further, spinal operation perforate provided by the invention is navigated detection system, can also have such feature: also comprise voice alarm module, for when myograph sensor receives the strong signal of muscle contraction, send alarm signal.
Further, spinal operation perforate provided by the invention is navigated detection system, can also have such feature: the top of electricity irritation probe is passive metal spheroid.
Further, spinal operation perforate provided by the invention is navigated detection system, can also have such feature: myograph detection module comprises four pieces of myograph sensors, is positioned over respectively on the extremity of patient.
Further, spinal operation perforate provided by the invention is navigated detection system, can also have such feature: myograph sensor is myograph acceleration transducer.
Invention effect and effect
The invention provides a kind of spinal operation perforate to navigate detection system, comprise exciting current module, current processing module, electricity irritation probe, myograph detection module and judge display module, the muscle contraction of myograph detection module to screw placement place is adopted to detect, judge punch position, because myograph does not have signal below the threshold value of electricity irritation, have certain selectivity to signal, wave noise is less, is more conducive to the determination of punch position.
Accompanying drawing explanation
Fig. 1 is the structural representation of spinal operation perforate of the present invention navigation detection system.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
Fig. 1 is the structural representation of the spinal operation perforate navigation detection system of the present embodiment.
As shown in Figure 1, spinal operation perforate navigation detection system 100 comprise be linked in sequence exciting current module 1, current processing module 2, electricity irritation probe 3, myograph detection module 4, judge display module 5 and voice alarm module 6.
Exciting current module 1 is for generation of stimulating current; Current processing module 2, for filtering stimulating current, is become certain electric current within the scope of 1mA ~ 15mA, prevents excessive the generation human body of electric current from injuring; The top of electricity irritation probe is passive metal spheroid, for the electric current after process is conducted to probes touch position.In pedicle screw implantation, electricity irritation probe is for stretching into the nail road of perforate, and when following closely position, road too near nerve root, nerve can conductive electric current, and then when controller, muscle is subject to nerve stimulation and produces contraction.
Myograph detection module 4 comprises four pieces of myograph sensors, is positioned over respectively on extremity, and the flesh produced during for collecting described muscle contraction moves signal; Judge that the intensity that display module 5 pairs of fleshes move signal is analyzed, it shown with the form of audio-visual picture, be convenient to doctor's Real Time Observation stimulus intensity, judge the intensity that flesh moves signal, when overflow, voice alarm module 6 sends audio alert simultaneously.
In the present embodiment, the electroshock threshold that nerve is subject to is 6mA, when only having the intensity of electricity irritation to be greater than 6mA, can cause muscle contraction.Meanwhile, when myograph sensor receive stronger flesh move signal time, phonetic alarm device sends audio alert.
Judgement display module in the present embodiment is computer, and it also plays the effect of control device, controls, regulate simultaneously to the intensity of stimulating current whole navigation checkout equipment.
The myograph sensor of the present embodiment is light weight, highly sensitive myograph acceleration transducer.
The spinal operation perforate navigation detection system of the present embodiment to the localization method of punch position is: by the diverse location at electricity irritation probe boosting operation position, when phonetic alarm device sends warning, illustrates that the position that probe stimulates is nerve; Under the galvanism of same intensity, if phonetic alarm device does not send warning, and raising current intensity does not have audio alert to send yet, and illustrate that myograph detection module does not receive myograph signal, the stimulation location of probe is the osseous tissue of suitable perforate.
Embodiment effect and effect
Present embodiments provide a kind of spinal operation perforate to navigate detection system, comprise exciting current module, current processing module, electricity irritation probe, myograph detection module and judge display module, the muscle contraction of myograph detection module to screw placement place is adopted to detect, judge punch position, because myograph does not have signal below the threshold value of electricity irritation, have certain selectivity to signal, wave noise is less, is more conducive to the determination of punch position.
The invention is not restricted to the scope of detailed description of the invention; to those skilled in the art; as long as various change to limit and in the spirit and scope of the present invention determined in described claim; these changes are apparent, and all innovation and creation utilizing the present invention to conceive are all at the row of protection.
