Abstract

The invention relates to a direction arc for precise puncture of intracranial lesion which is an auxiliary apparatus used for precise directional puncture of intracranial nidus for patients by utilizing CT (computerized tomography) or MRI (magnetic resonance imaging). The intracranial lesion precise puncture direction arc comprises an arc-shaped support (4) which is an arc-shaped structure of high toughness and not easy to deform, a single foot end (5) of the arc-shaped support (4) is provided with a single foot (A), a double foot end (1) of the arc-shaped support (4) is provided with double feet (B and C), the midpoint of the line between the double feet is point O, and the three feet are devices which can be fixed on a scalp. A correction rod (3) is fixedly arranged on the double foot end (1) of the arc-shaped support (4), the correction rod (3) and the line between OA are in parallel to detect and eliminate the phenomenon that the correction rod (3) and the puncture direction OA are not in parallel due to the deformation of the arc-shaped bracket (4), and the correction rod (3) plays a role of correction. The three feet fixing devices can be bolts with outer fastening buttons or small sucker structures. The direction arc for precise puncture of intracranial lesion is simple in structure, easy to use, precise and rapid in positioning and low in production cost and deserves to be popularized.

Description

The intracranial lesion directed bow that accurately punctures

Affiliated technical field:

The present invention relates to a kind of CT of utilization or MRI to the auxiliary device of patient's intracranial lesion accurate pointing puncture.

Background technology:

CT or MRI check it is pathological changes Main Means in the diagnosis body.Can diagnose the size that whether has pathological changes in the body and determine focus by CT or MRI scanning, we often carry out stereotactic puncture suction or biopsy according to image data to intracranial lesion (such as cerebral hemorrhage, brain abscess, tumor etc.).Accurate puncture needs three key elements: point of puncture, puncture direction and the degree of depth, wherein point of puncture can be determined according to anatomic landmark or the body surface symbol that presets thing, paracentesis depth can be determined by CT or MRI as required, but the puncture direction is difficult assurance, the less deviation of puncture direction may cause the skew larger apart from target spot, and therefore accurate puncture direction is particularly important.In order to address the above problem, the medical worker has invented multiple in-vitro directed method, has all obtained certain effect on the accuracy that solves intracranial lesion body surface location, but the instrument that they take is comparatively complicated, operates comparatively loaded down with trivial details.

Summary of the invention:

The object of the invention is to overcome the shortcoming of above-mentioned intracranial lesion stereotactic puncture, a kind of orienting device more accurate, reliable, easy to use is provided.

The object of the present invention is achieved like this: it comprises a bow type support, bow type support is the large on-deformable arc-shaped structure of toughness, the two ends of bow type support, one end has monopodia A, and the other end has biped B and C, and BC line mid point is the O point, each foot is the device that can be fixed on the scalp, be installed with a par at bow type support biped end, be installed with a calibrating stem on the hunchbacked midpoint of bow type support, calibrating stem is parallel with the AO line.

During use, by CT or the MRI data of reading reference inspection focus is made Primary Location, and two intersection points of will puncture direction and scalp, it is point of puncture and offside point, use the witness marker substance markers, then check CT or MRI and correct point of puncture and offside point, and reaffirm paracentesis depth according to point of puncture and target spot distance.This device monopodia A is aimed at the offside point, and O point aligning point of puncture utilizes the fixture of tripodia to be fixed on the scalp, and whether settle the standard bar and calibrating stem be parallel to each other.Because calibrating stem is positioned at location bow midpoint, and it is parallel with the AO line, if the fixing cast that too tightly causes of tripodia, calibrating stem can be still parallel with the AO line, but this moment, not parallel situation can appear in calibrating stem and calibrating stem, can get rid of the error that the location cast causes in the fixation procedure, in order to avoid cause par and the inconsistent situation of puncture direction at this point.Settle the standard bar with after calibrating stem is parallel, can be entered by point of puncture by existing routine operation (soft passage or hard passage method) puncture needle or drainage tube, be parallel to the puncture of par direction, paracentesis depth H determines that according to CT or MRI puncture needle or drainage tube just can be accurate to and reach target spot thus.The present invention is simple in structure, easy to use, accurate positioning is rapid, and cost of manufacture is cheap, is worthy to be popularized.

Description of drawings:

Fig. 1 is structure principle chart of the present invention;

Fig. 2 is the left view of Fig. 1;

Fig. 3 is that the M of Fig. 1 is to view.

Wherein: 1-biped end is respectively B and C with biped; The 2-par; The 3-calibrating stem; 4-bow type support; 5-monopodia end is with monopodia A.

The specific embodiment:

Main body of the present invention is a bow type support 4, bow type support is the large on-deformable arc-shaped structure of toughness, on the monopodia end 5 of bow type support 4 monopodia A is arranged, biped B and C (BC line mid point is the O point) are arranged on the biped end 1, tripodia is the device that can be fixed on the scalp, be installed with a par 2 at bow type support 4 biped ends 1, be installed with a calibrating stem 3 on the hunchbacked midpoint of bow type support 4, calibrating stem 3 is parallel with the AO line, in order to find in use and get rid of the par that causes because of directed cast and the inconsistent situation of puncture direction OA, play calibration function for par 2.The fixture of tripodia can be the bolt that the outer end band screws button, also can be the structures such as small-sized sucker.

Claims
