AI Technical Summary

Technical Problem

In X-ray guided interventional surgery, soft tissues are not easily visualized and individual differences in bones make it difficult to accurately locate the puncture path. Existing auxiliary tools lack fixation devices and easily obscure bony landmarks, affecting the accuracy of puncture.

Method used

Design an image-guided puncture surgery positioning aid, comprising adhesive tape, a main longitudinal tube, a main transverse tube, an auxiliary longitudinal tube, and an auxiliary transverse tube, which are arranged in a cross-shaped mesh structure. The tubes contain metal particles and angle scale lines for imaging and positioning under X-rays, and to assist in determining the puncture path.

Benefits of technology

It improves the positioning efficiency and accuracy of puncture surgery, reduces the obstruction of bony landmarks, enhances the accuracy of needle insertion angle judgment, and simplifies puncture operation.
