Abstract
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 instruction of 0-180 degree, described angle pointer (2) for hollow-core construction so that puncture needle passes through, the center of 0 degree and 180 degree line on graduated tile (1) is provided with drive rod (3), and angle pointer (2) is installed on described drive rod (3).The present invention fundamentally overcomes the problem of puncture blindness, can not only improve the accuracy of puncture, and can improve the speed of puncture, improves medical level.
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, need utilize puncture needle to sample or medicine is delivered to affected area when testing to focus and treating, but in most of the cases, focus is all hidden between human normal organ, in order to prevent from damaging normal organ during puncture, just the injury that puncture doctor must select suitable puncture angle can prevent normal organ, for this reason, CT scan must be utilized before puncturing to position focus, observe and calculate best puncture angle.After obtaining desirable puncture angle, the angle that doctor just obtains according to scanning punctures with feeling, because puncture needle can not show puncture angle, therefore error during practical operation is general all larger, doctor is needed 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 object of the invention is rely on the experience of operator completely for the work angle of existing puncture procedure and feel to carry out, be easy to puncture inaccurate injury normal structure occurs, cause the problem of potential safety hazard, design a kind of for what puncture, can ensure that hornwork is determined in the puncture that the ideal value of lancet puncture angle and CT scan gained fits like a glove.
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 instruction of 0-180 degree, described angle pointer 2 is for hollow-core construction is so that puncture needle passes through, the center of 0 degree and 180 degree line on graduated tile 1 is provided with drive rod 3, and angle pointer 2 is installed on described drive rod 3.
The bottom of the one side that described graduated tile 1 is not with a scale is connected with gripper shoe or support bar 4.
Described drive rod 3 be manual actuation bar or, manual actuation bar is installed with the locking nut making it locate.
Described drive rod 3 is connected with pulsed driven micro machine 5, and pulsed driven micro machine 5 is connected with pulse generating circuit 6, and pulse generating circuit 6 is connected with the output of CT scanner 7.
Beneficial effect of the present invention:
The present invention fundamentally overcomes 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 manual type structure, also can realize automatically determining angle.
Structure of the present invention is simple, easily manufactured.
Accompanying drawing explanation
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.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further illustrated.
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 a patient body, the back side of graduated tile 1 finally connects a gripper shoe or support bar 4, described graduated tile 1 is provided with the angle index instruction of 0-180 degree, described angle pointer 2 is for hollow-core construction is so that puncture needle passes through, the center of 0 degree and 180 degree line on graduated tile 1 is provided with drive rod 3, angle pointer 2 is installed on described drive rod 3, the certain distance of drive rod 3 can be exposed in one end that angle pointer 2 is connected with drive rod 3, also can be concordant with drive rod surface.During concrete enforcement, first at the home position place of graduated tile 1, a bearing can be installed, again drive rod 3 is fixed within the bearing to facilitate rotation, simultaneously, rock in order to when preventing from puncturing, angle pointer 2 is stressed, can on drive rod 3 spinning locking nut making it locate, by the corner of locking nut restriction drive rod, thus realize angle pointer 2 determine angle.
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 a patient body, the back side of graduated tile 1 finally connects a gripper shoe or support bar 4, described graduated tile 1 is provided with the angle index instruction of 0-180 degree, described angle pointer 2 is for hollow-core construction is so that puncture needle passes through, the center of 0 degree and 180 degree line on graduated tile 1 is provided with drive rod 3, angle pointer 2 is installed on described drive rod 3, the certain distance of drive rod 3 can be exposed in one end that angle pointer 2 is connected with drive rod 3, also can be concordant with drive rod surface.During concrete enforcement, first at the home position place of graduated tile 1, a bearing can be installed, again drive rod 3 is fixed within the bearing to facilitate rotation, drive rod 3 and pulsed driven micro machine 5, pulsed driven micro machine 5 is connected with pulse generating circuit 6, and pulse generating circuit 6 is connected with the output of CT scanner 7.When after CT scanner determines the puncture angle of what a the best, this angle being outputted in pulse generating circuit 6 in the mode of the signal of telecommunication, pulse generating circuit 6 calculates the angle that the umber of pulse matched with required puncture angle is transported to control impuls electric machine rotation in pulsed driven micro machine 5, and the angle rear motor turning to setting is automatically locked at required angle.
The part that the present invention does not relate to prior art that maybe can adopt all same as the prior art is realized.
