Tie up reconstruction technique can Arbitrary Rotation, the space structure of calculus is analyzed, helps to formulate optimal rubble, take the cubic meter of stone
Case improves puncture success rate.
CT can clearly show that the relationship of kidney and surrounding organ, formulated by CT and puncture pathway, to reduce adjacent organ
Damage.This research is quasi- pass through preoperative simulation operation position and pastes designation strip progress spiral CT scan, with Accurate Calibration point of puncture with
The angle and depth punctured is calculated, our early-stage studies guarantee to puncture the angle of expansion by orientation angle indicator.But its
Level meter sensibility on orientation angle indicator is not good enough, and can not show real-time angular.

Beneficial effect using above-mentioned further scheme is: by high-precision, self-correcting, can show, holds, low-power consumption electricity
The angle of sub- display screen real-time display puncture needle or expander, thus guarantee the smooth foundation of puncture channel, it is clear to improve calculus
Except rate, reduces and surrounding organ is avoided to damage and the generation of the complication such as bleeding.
Detailed description of the invention
Fig. 1 is the utility model main view；
Fig. 2 is the principles of the present invention block diagram；
Fig. 3 is the calibration mode schematic diagram of the utility model.
In attached drawing, parts list represented by the reference numerals are as follows:
1, puncture needle, 2, shell, 3, display screen, 4, initiation button, 5, operation button.
Specific embodiment
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining that this is practical
It is novel, it is not intended to limit the scope of the utility model.
As illustrated in fig. 1 and 2, percutaneous kidney is minimally invasive takes the external position indicator of stone operation, including puncture needle 1, on the puncture needle 1
Equipped with the positioning device for being used to indicate its puncture direction.The positioning device includes shell 2, acceleration transducer, horizontal location
Sensor and CPU microprocessor；The acceleration transducer, the horizontal location sensor and the CPU microprocessor are equal
In the shell 2, and the acceleration transducer and the horizontal location sensor pass through A/D conversion circuit respectively and connect
Connect the CPU microprocessor.The lateral surface of the shell 2 is equipped with the display for showing the CPU microprocessor calculated result
Screen；It is equipped in the shell 2 as the acceleration transducer, the horizontal location sensor, the CPU microprocessor and institute
The power supply for stating A/D conversion circuit offer electric energy is preferred: the power supply is lithium battery.
The lateral surface of the shell 2 is additionally provided with the initiation button 4 calibrated for operation consent to patient body position and uses
The operation button 5 in the puncture direction of the puncture needle 1 is indicated in operation.By electronics " acceleration transducer ", " horizontal location passes
The electric analoging signal in direction and angle of the sensor " output compared with horizontal, is sent to A/D conversion circuit and becomes digital quantity, then through CPU
The program of microprocessor is analyzed, is calculated, and shows real-time angle, 0 bit correction of level etc. in liquid crystal display.
Determine that percutaneous nephrolithy takes stone operation position, the row CT scan inspection after Ipsilateral pastes designation strip, according to rib cage and mark
Item selects point of puncture on CT picture and controls direction and the angle of puncture needle 1 or expander by external position indicator.It is described below
One specific course of work:
System can work in two modes: calibration mode and operational mode.
Since the sagittal plane of patient is not necessarily vertical with the earth, and since from factor, we may take horizontally-inclined to patient
Position, so external position indicator should work first after powering on presses initiation button 4 in the calibration mode, as shown in figure 3, will puncture
Needle 1 is obtained by being shelved on the intersection of operating table b and vertical puncturing face d using acceleration transducer and horizontal location sensor
The angle theta of current procedure platform b and the earth horizontal reference1。
After calibration, enter operational mode after external position indicator pressing operation button 5.At this point, by the needle point of puncture needle 1
It is placed on point of puncture e, using point of puncture as the tail portion of the mobile puncture needle 1 in the center of circle in vertical puncturing face, is passed by horizontal location
Sensor obtains self calibration direction a, then the folder of current puncture needle 1 and geodetic datum horizontal plane can be measured by acceleration transducer
Angle θ2, calculated by CPU microprocessor, the angle theta between puncture needle 1 and operating table can be being shown in liquid crystal display 32-
θ1, practical puncture direction a can be indicated by the angle.
Utilize acceleration transducer measurement angle principle: acceleration transducer has a sensitive axes, when the sensitive axes with
When angle is presented in gravity direction, acceleration transducer will export the voltage of certain amplitude, also, voltage value and angle at than
Example.The sensitive axes of acceleration transducer are consistent with the direction of puncture needle 1, after powering under self-calibration mode, acceleration sensing
Device exports an initial voltage, and CPU microprocessor can calculate initial angle after converting by A/D.In operation, system is in
Operational mode, each posture of puncture needle 1 can generate a new angle, and CPU microprocessor is by the angle and initial angle
Degree makes the difference, and can calculate the angle of current puncture needle and operation table surface, and the angle is shown by liquid crystal display 3
Come, doctor can be instructed to guarantee operation precision.Its angle precision can be controlled in ± 0.1 °, display refresher rate: 5 times/second.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
