Description

Interventional therapy positioning device under magnetic resonance guidance

Technical Field

The utility model belongs to the technical field of the medical treatment, concretely relates to intervene treatment positioner under magnetic resonance guide.

Background

Magnetic resonance guided interventional therapy is an emerging technology in recent years, and mainly aims to apply a magnetic resonance guided instrument to enter a focus so as to achieve the purpose of diagnosing or treating diseases. Magnetic resonance is used as an interventional guidance tool, compared with CT and ultrasonic guidance methods and the like, the tissue contrast is better, the spatial resolution can reach submillimeter level, both lesion location and interventional guidance are beneficial, and the magnetic resonance has the capacity of multi-plane and three-dimensional volume reconstruction, and can comprehensively evaluate the important anatomical relation between an interventional target focus and adjacent tissues. The excellent soft tissue resolving power of magnetic resonance can better judge the tissue change after interventional therapy, and the treatment effect is more convenient. Magnetic resonance guided interventional therapy can be applied to minimally invasive interventional therapy such as argon-helium knife freezing, radiotherapy and chemotherapy particle implantation or rotary-cut intervertebral disc radio frequency ablation therapy and the like at present. Need carry out the location and the fixing of pjncture needle in magnetic resonance guided intervention treatment, do not have the device that is applied to clinically specially at present, will self-control according to certain regular permutation's cod-liver oil granule laminating patient skin usually, because cod-liver oil can be on magnetic resonance, conveniently fix a position the position of pathological change, but often need fix a position the point of puncture, the degree of depth and the angle of inserting the needle at the puncture in-process, can't confirm the angle of puncture with the self-control scheme at present and fix the pjncture needle after the puncture. Because the lesion may be small, moving the puncture needle may cause the interventional device to remove the lesion site, resulting in treatment failure.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve the weak point among the prior art, provide an intervene treatment positioner under magnetic resonance guide, adopt this positioner to conveniently confirm the pathological change position to can confirm puncture point, the depth of needle and angle of inserting.

In order to solve the technical problem, the utility model adopts the following technical scheme: a magnetic resonance guided interventional therapy positioning device comprises a positioning sticker and a puncture positioning assembly, wherein an adhesive layer is arranged on the periphery of the positioning sticker, a release paper layer is adhered on the adhesive layer, a row of longitudinal positioning developing points, a plurality of rows of transverse positioning developing points and a plurality of rows of puncture holes are arranged on the positioning sticker, the length direction of one row of longitudinal positioning developing points is arranged along the diagonal direction of the positioning sticker, and each row of transverse positioning developing points is positioned between two adjacent rows of puncture holes;

the longitudinal positioning developing point and the transverse positioning developing point are capsule body structures filled with cod liver oil, and the radius of the longitudinal positioning developing point is larger than that of the transverse positioning developing point;

the puncture positioning assembly comprises a positioning plate, the two sides of the positioning plate are connected with adhesive tapes through pulling belts, a long hole is formed in the positioning plate, a semicircular protractor is fixed on the positioning plate, the circle center of the protractor is hinged to a puncture positioning pipe through a bolt, the bolt is fixed to the lower portion of the puncture positioning pipe, the bolt is rotatably connected to the circle center of the protractor, a positioning nut is connected to the end portion of the bolt in a threaded mode, the lower end portion of the puncture positioning pipe is arranged in the long hole in a penetrating mode, and the upper portion of the puncture positioning pipe is connected with.

Adopt above-mentioned technical scheme, the utility model discloses following beneficial effect has: the utility model discloses utilize the location subsides to accomplish the location to the tumour, confirm puncture position, angle and degree of depth, utilize puncture locating component to accomplish the puncture work that corresponds, overall structure reasonable in design, convenient to use, it is multiple functional.
