[0001] The present invention relates to the technical field of medical devices, and particularly relates to a puncture positioning device for oncology. Background Art

[0002] In the diagnosis and treatment process of oncology, puncture biopsy is one of the important means to obtain pathological diagnosis. Precise puncture positioning is crucial for improving the success rate of biopsy, reducing damage to the patient's normal tissues, and subsequent accurate diagnosis and treatment. However, there are some problems in the actual use of existing puncture positioning devices. For example, some devices are difficult to achieve multi-angle precise adjustment of the puncture needle, resulting in the inability to accurately puncture when facing tumor lesions at different positions and angles. Moreover, the adjustment structures of some devices are not flexible enough, and the operation is inconvenient, affecting the puncture efficiency. In addition, the fixing and supporting methods on the bed board are not stable and convenient enough, and cannot well adapt to the body types and examination needs of different patients.

[0032] Working principle and usage process of the present invention:

[0033] Installation and adjustment of the support structure:

[0034] Place the two support structures 1 opposite to each other on both sides of the bed board 2, so that one side of the support rod 101 where the connecting rod 103 is provided is attached to the side of the bed board 2. Insert the connecting rod 103 of one support structure 1 into the connecting pipe 104 of the other support structure 1. By tightening the hand-tightening bolt 105, the two support structures 1 are fixedly connected. According to actual needs, the hand-tightening bolt 105 can be loosened to adjust the insertion depth of the connecting rod 103 in the connecting pipe 104, thereby changing the distance between the two support structures 1 to adapt to bed boards 2 of different widths. At the same time, by loosening the hand-tightening bolt 109, the insertion height of the adjusting rod 301 in the sleeve 108 can be adjusted, and then the height of the entire device can be adjusted to meet the requirements of different operating heights. After adjustment, tighten the hand-tightening bolt 109 to fix the adjusting rod 301;

[0035] Operation of the first adjusting structure:

[0036] Loosen the hand-tightening bolt 303, and the adjusting pipe 302 can be moved along the adjusting rod 301, thereby driving the adjusting ring 304 and the upper adjusting structure 4 above to move horizontally. After moving to the appropriate position, tighten the hand-tightening bolt 303 to fix the adjusting pipe 302. When the angle of the puncture needle device needs to be finely adjusted, loosen the hand-tightening bolt 308 and rotate the adjusting ring 306. The adjusting ring 306 rotates relative to the adjusting ring 304 through the annular turntable 307. When the appropriate angle is adjusted, tighten the hand-tightening bolt 308 so that its bottom end abuts against the corresponding limiting hole 305 to fix the angle of the adjusting ring 306;

[0037] Use of the second adjusting structure,

[0038] Place the puncture needle device in the fixing clip 406 and clamp it. By rotating the grip rod 405, drive the rotating cylinder 404 to rotate in the adjusting groove 402, thereby realizing multi-angle adjustment of the puncture needle device to accurately align the tumor lesion position for puncture operation.
