Abstract
The invention relates to a puncture locating device which is characterized by comprising a scale plate (1) and an angle pointer (2), wherein the scale plate (1) is provided with angle scale indication of 0-180 degrees; the angle pointer (2) has a hollow structure, and a puncture needle can conveniently pass through the angle pointer; a driving rod (3) is arranged at the center of a connecting line between 0 degree and 180 degrees on the scale plate (1); and the angle pointer (2) passes through the driving rod (3). The puncture locating device fundamentally solves the problem of puncture blindness, thus not only improving the puncture accuracy, but also accelerating the puncture speed; and therefore, the medical level is improved.
Description
Technical field
The present invention relates to a kind of medical auxiliary apparatus, especially a kind of and the matching used localizer of puncture needle, specifically a kind of puncture locator.
Background technology
At present, when focus being tested and treat, need to utilize puncture needle to take a sample or medicine is delivered to affected area, but in most of the cases, focus all is hidden between the human normal organ, in order when preventing from puncturing normal organ to be damaged, just the puncture doctor must select suitable puncture angle can prevent injury to normal organ, for this reason, before puncturing, must utilize CT scan that focus is positioned, observe and calculate best puncture angle.After obtaining desirable puncture angle, the doctor just punctures with feeling according to the angle that scanning obtains, because puncture needle can not show puncture angle, therefore the error during practical operation is generally all larger, need the doctor rule of thumb constantly to adjust puncture angle with sensation, be easy to cause puncture inaccurate, form potential safety hazard, the solution that this be there is no at present.
Summary of the invention
The objective of the invention is work angle for existing puncture procedure relies on operator's experience fully and feels to carry out, be easy to occur the inaccurate injury of puncture normal structure, cause the problem of potential safety hazard, design a kind ofly for puncture, can guarantee that the puncture that the ideal value of lancet puncture angle and CT scan gained fits like a glove decides hornwork.
Technical scheme of the present invention is:
A kind of puncture locator, it is characterized in that it comprises a graduated tile 1 and an angle pointer 2, described graduated tile 1 is provided with the angle index indication of 0-180 degree, described angle pointer 2 for hollow-core construction so that puncture needle pass through, 0 degree on graduated tile 1 and the center of 180 degree lines are equipped with drive rod 3, and angle pointer 2 is installed on the described drive rod 3.
Described graduated tile 1 is not connected with gripper shoe or support bar 4 with the bottom of the one side of scale.
Described drive rod 3 be the manual actuation bar or, be installed with the locking nut that makes its location on the manual actuation bar.
Described drive rod 3 is connected with pulsed driven micro machine 5, and pulsed driven micro machine 5 links to each other with pulse generating circuit 6, and pulse generating circuit 6 links to each other with the output of CT scanner 7.
Beneficial effect of the present invention:
The present invention has fundamentally overcome the problem of puncture blindness, can not only improve the accuracy of puncture, and can improve the speed of puncture, improves medical level.
The present invention both can manufacture the manual type structure, also can realize automatically deciding the angle.
The present invention is simple in structure, and is easily manufactured.
Description of drawings
Fig. 1 is pure mechanically driver type structural representation of the present invention.
Fig. 2 is automatic fixed angle type structural representation of the present invention.
The specific embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
Embodiment one.
As shown in Figure 1.
A kind of puncture locator, it is characterized in that it comprises the semicircle sector structure of a graduated tile 1() and an angle pointer 2, for the ease of graduated tile 1 is placed on the patient body, a last gripper shoe or the support bar 4 of connecting in the back side of graduated tile 1, described graduated tile 1 is provided with the angle index indication of 0-180 degree, described angle pointer 2 for hollow-core construction so that puncture needle pass through, 0 degree on graduated tile 1 and the center of 180 degree lines are equipped with drive rod 3, angle pointer 2 is installed on the described drive rod 3, the end that angle pointer 2 links to each other with drive rod 3 can expose the certain distance of drive rod 3, also can be concordant with the drive rod surface.During implementation, can at the home position place of graduated tile 1 bearing be installed first, again drive rod 3 is fixed in the bearing and rotates with convenient, simultaneously, angle pointer 2 stressed rocking in order to prevent from puncturing, can be on drive rod 3 locking nut that makes its location of spinning, by the corner of locking nut restriction drive rod, thereby realize the angle of deciding of angle pointer 2.
Embodiment two.
As shown in Figure 2.
A kind of puncture locator, it comprises the semicircle sector structure of a graduated tile 1() and an angle pointer 2, for the ease of graduated tile 1 is placed on the patient body, a last gripper shoe or the support bar 4 of connecting in the back side of graduated tile 1, described graduated tile 1 is provided with the angle index indication of 0-180 degree, described angle pointer 2 for hollow-core construction so that puncture needle pass through, 0 degree on graduated tile 1 and the center of 180 degree lines are equipped with drive rod 3, angle pointer 2 is installed on the described drive rod 3, the end that angle pointer 2 links to each other with drive rod 3 can expose the certain distance of drive rod 3, also can be concordant with the drive rod surface.During implementation, can at the home position place of graduated tile 1 bearing be installed first, again drive rod 3 is fixed in the bearing and rotates with convenient, drive rod 3 and pulsed driven micro machine 5, pulsed driven micro machine 5 links to each other with pulse generating circuit 6, and pulse generating circuit 6 links to each other with the output of CT scanner 7.After CT scanner is determined the puncture angle of what a the best, the mode of this angle with the signal of telecommunication outputed in the pulse generating circuit 6, pulse generating circuit 6 calculates the angle that the umber of pulse that is complementary with required puncture angle is transported to control impuls electric machine rotation in the pulsed driven micro machine 5, and the angle rear motor that turns to setting is automatically locked at required angle.
The part that the present invention does not relate to all prior art that maybe can adopt same as the prior art is realized.
