Description

Technical Field

[0001] The utility model relates to the technical field of composite pipes, and more specifically, to a composite guide tube developing ring fixing tool. Background Art

[0002] In the medical field, developing rings are used to improve visibility in imaging equipment, such as X-rays, CT scans or MRIs. The size of the developing ring should match the diameter of the catheter to ensure that the position of the catheter can be clearly seen during imaging. The size of the developing ring usually depends on the required application scenario and the size of the catheter. When performing static quality inspection on the developing ring and cleaning and disinfecting the developing ring, the position of the developing ring needs to be supported and fixed to improve the convenience of inspection and cleaning.

[0003] In the existing technology, the fixed tooling cannot be adapted to support developing rings of various sizes, which in turn affects the compatibility and adaptability of the fixed tooling. If fixed tooling of different sizes is purchased, the processing cost of the developing ring will be greatly increased. At the same time, when inspecting and cleaning the developing ring, it is necessary to constantly adjust and fix the angle of the developing ring. However, the existing fixed tooling has a single structure and function, which affects the convenience of operating the developing ring. Utility Model Content
