CT guided puncture positioning film

Abstract

The invention discloses a CT guided puncture positioning film. The CT guided puncture positioning film comprises a grid film sheet, wherein horizontal coding grids are arranged outside horizontal grids in the grid film sheet; vertical coding grids are arranged outside vertical grids in the grid film sheet; the number of the horizontal coding grids is the same as that of the horizontal grids; the number of the vertical coding grids is the same as that of the vertical grids; horizontal ribs are arranged in the horizontal coding grids, and form horizontal scale codes in sequence; vertical ribs are arranged in the vertical coding grids, and form vertical scale codes in sequence; the grid film sheet is formed by mixing a flexible polymer material and a paramagnetic material, and can absorb and block X-rays to avoid generation of an artifact; through the horizontal coding grids and the vertical coding grids, quick and accurate positioning on the grid film sheet during CT scanning can be realized conveniently. The CT guided puncture guiding film is simple in structure, convenient to use, low in cost, and suitable for clinical popularization and application in a wide range.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a CT puncture guiding positioning film. Background technique [0002] CT-guided interventional technology is a relatively safe, reliable, simple and quick operation of minimally invasive treatment technology. [0003] Given that CT scanning can obtain high-resolution images, it can clearly display the cross-sectional anatomy of the puncture plane in the patient's body, and accurately display the location, size, shape, internal condition and spatial relationship of the lesion with the surrounding structures, especially the adjacent blood vessels and nerves. The distribution and travel situation of etc. Precisely determine the position of the puncture point, needle insertion direction and depth before puncture, and scan during puncture to observe the specific position of the needle insertion, and can try to avoid important tissues and organs in the body along the puncture path to im...

Problems solved by technology

[0004] Although the dedicated CT and MRI navigation and positioning systems are accurate in positioning, the equipment is expensive, and the structure of various positioning frames is complicated, and the operation is difficult. Basic hospitals cannot afford it. Even if laser navigation and positioning are used, not only the operation is cumbersome, but also the cost is high. Increased economic burden, but also brought inconvenience to the work of medical staff

[0005] At present, various body surface positioning stickers (apparatus), which are widely used clinically, have achieved certain results in solving the accuracy of body surface positioning of lesions in the body, but the methods they adopt are not accurate enough, which affects the later treatment; some mosaic The metal in the CT scan produces radial artifacts, which cannot meet the clinical practical application
