Abstract

The invention discloses a puncture fixing device capable of realizing three-dimensional regulation under CT guidance. The puncture fixing device comprises a support frame, a vertical rod, an angle plate and a positioning block, wherein the vertical rod is movably arranged on the support frame; one side of the angle plate is hinged to the lower end of the vertical rod; the positioning block is arranged at the other side of the angle plate and is used for fixing a puncture needle; a through groove is formed in the vertical rod; one side, hinged to the vertical rod, of the angle plate is provided with a regulating plate vertical to the angle plate; the regulating plate can be inserted into the through hole when rotating along with the angle plate, and is fixed on the vertical rod through a regulating screw bolt; and the positioning block can rotate around a circle center of the angle plate, and realizes rotation locking through a fastening screw bolt. The puncture fixing device has the advantages that by changing the positions of the angle plate and the regulating plate and the position relationship between the angle plate and the regulating plate and rotating the lower rod body, the puncture needle can swing in the vertical plane of the angle plate, so that the precise positioning is realized; the risk of complications is reduced; and meanwhile, the operation by a doctor is convenient.

Description

technical field [0001] The invention relates to a three-dimensionally adjustable puncture fixing device under the guidance of CT, which belongs to the technical field of medical instruments. Background technique [0002] CT-guided percutaneous biopsy is widely used in clinical practice, which greatly improves the diagnosis rate of space-occupying diseases. The traditional method is to determine the puncture point after the CT scan, and the doctor manually adjusts the direction of the puncture needle to insert the needle based on experience. This method cannot be accurately positioned and has certain limitations. Most of the existing positioning devices include an adjustable angle meter, which can adjust the puncture needle in the cross section. However, in the long-term application, we found that some chest lesions are deep from the surface of the body, close to the large blood vessels, and may be covered by ribs. In addition to adjusting the angle and depth of the puncture...
