Abstract
The utility model discloses a captive test (CT) puncture guide positioning device. The CT puncture guide positioning device comprises an arc-shaped positioning frame, a guiding module, a transverse slide rod and a guiding needle, wherein the arc-shaped positioning frame is provided with the transverse slide rod, the transverse slide rod is fixedly provided with the guiding module, and the guiding module is fixedly provided with the guiding needle. According to the CT puncture guide positioning device, a puncture point, a puncture angle and the puncture depth can be positioned accurately, and targets on the same CT tangent plane or on different CT tangent planes of the puncture point all can be punctured accurately. The CT puncture guide positioning device is low in cost, convenient to use and easy to operate and promote.
Description
Technical field
This utility model belongs to the medical instruments technical field, is a kind of CT guiding puncture position finder concretely.
Background technology
At present, the medical worker is when carrying out the operation of CT localised puncture, body surface in the puncture target sticks the CT Position Scale first, by CT scan, according to the relation of metal monumented point on the scintigram with the puncture target, make point of puncture and puncture angle, then at the selected point of puncture inserting needle of human body, mainly rely on operator's experience and technical merit to puncture to the target in the imagination, need repeatedly CT scan to confirm the puncture needle position, complex operation, the radiation dose that the patient bears is large.
At present, the Pinpoint system applies that is comprised of the three-dimensional location of laser positioning, reconstruction of three-dimensional images and mechanical hand etc. is in the CT interventional therapy, location, fixed point are accurately, Robot actions is stable, monitor can show puncture inserting needle track, puncture to small lesion or deep focus has more advantage, be a much progress of CT interventional therapy, but apparatus expensive is difficult to again Grass-roots Hospital.
Summary of the invention
The purpose of this utility model provides a kind of:
CT guiding puncture position finder can accurately be made point of puncture and puncture angle and paracentesis depth, and the CT guiding puncture position finder that the target on the same or not same CT tangent plane all can accurately puncture for point of puncture, cheap, convenient, easy operating and carrying out.
The technical solution of the utility model is:
CT guiding puncture position finder, comprise: arc locating rack, bootstrap module, horizontal sliding bar, guide needle, it is characterized in that: on the described arc locating rack described horizontal sliding bar is set, is fixedly installed described bootstrap module on the described horizontal sliding bar, be fixedly installed described guide needle on the described bootstrap module.
Described arc locating rack is 90 degree radians.
Described arc locating rack outer surface arranges even radian indentation.
Described horizontal sliding bar slides along described arc locating rack camber line, can confirm the angle of its horizontal plane or vertical by the radian indentation of described arc locating rack outer surface setting.
Described bootstrap module can move horizontally along described horizontal sliding bar, also can center on described horizontal sliding bar axial-rotation.
The puncture direction of described guide needle is axially vertical with described horizontal sliding bar.
Even scale is set on the needle body of described guide needle, can confirms the degree of depth that guide needle is thrust.
Described arc locating rack, bootstrap module, horizontal sliding bar, guide needle all adopt the Al-alloy metal material.The utility model has the advantages that: simple in structure, easy to operate, can accurately make point of puncture and puncture angle and the degree of depth, the characteristics such as all can accurately puncture of the target for point of puncture on the same or not same CT tangent plane.
Description of drawings
Below in conjunction with the embodiment accompanying drawing this utility model is described further:
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, arc locating rack, 2, horizontal sliding bar, 3, bootstrap module, 4, guide needle.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described:
CT guiding puncture position finder comprises: arc locating rack 1, horizontal sliding bar 2, bootstrap module 3, guide needle 4, wherein, horizontal sliding bar 2 is set on the arc locating rack 1, and be fixedly installed bootstrap module 3 on the horizontal sliding bar 2, be fixedly installed guide needle 4 on the bootstrap module 3; Arc locating rack 1 is 90 degree radians, and arc locating rack 1 outer surface arranges even radian indentation, and horizontal sliding bar 2 slides along arc locating rack 1 camber line, can confirm the angle of its horizontal plane or vertical by the radian indentation of arc locating rack 1 outer surface setting; Bootstrap module 3 can move horizontally along horizontal sliding bar 2, also can center on horizontal sliding bar 2 axial-rotations; The puncture direction of guide needle 4 and horizontal sliding bar 2 is axially vertical, and even scale is set on the needle body of guide needle 4, can confirm that guide needle 4 thrusts the degree of depth of human body.Arc locating rack 1, bootstrap module 3, horizontal sliding bar 2, guide needle 4 all adopt the Al-alloy metal material to make.
Work process of the present utility model is: the patient lies on the CT bed, patient body-surface sticks the quick Position Scale of CT, point of puncture, needle angle and the degree of depth have been calculated after the CT scan, general needle angle is the angle α of puncture needle and tumor line and CT operating board level, measure depth of needle, then this instrument is placed body surface top, puncture target cross section, make horizontal sliding bar 2 be positioned at the angle α scale place of arc locating rack 1, again with the bootstrap module 3 puncture guiding needles 4 most advanced and sophisticated points of puncture of aiming at, fix bootstrap module 3, re-use guide needle 4 and puncture.
Below only be preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., all should be included within protection scope of the present invention.
