AI Technical Summary
Existing pipe grinding devices for hypotube production lack an automated grinding structure, which causes workers to be tired and the grinding effect is poor.
A pipe grinding device consisting of an electric telescopic rod, a motor-driven screw and a hydraulic cylinder was designed to realize automatic clamping, rotation and grinding of the hypotube. The grinding process was automatically completed by the motor-driven constant-speed movement of the grinding pen and the descending movement of the hydraulic cylinder.
The automatic grinding of hypotubes is realized, which reduces the labor intensity of workers, improves the grinding effect and the overall quality of hypotubes, and facilitates the disassembly and maintenance of fixings.

Technical Field
[0001] The utility model relates to the technical field of hypotubes, in particular to a pipe grinding device for hypotube production. Background Art
[0002] A hypotube is a long metal tube with microengineered features throughout its entire length. It's a crucial component of minimally invasive catheters, used in conjunction with a balloon and stent to open blocked arteries. The balloon portion of the catheter is attached to the distal end of the hypotube, which then enters the body and pushes the balloon along the long, winding blood vessels toward the blocked artery. During this process, the hypotube must avoid kinking while navigating smoothly through the human anatomy.
[0003] The China Patent Network discloses a pipe grinding device for hypotube production, with publication number CN219837618U. Although it can grind multiple hypotubes simultaneously with high grinding efficiency and without bending, the patent lacks a corresponding structure for mounting a grinding pen. This means that when grinding the hypotubes, workers still need to hold the grinding pen manually. This increases worker fatigue and results in poor grinding effect on the hypotubes, thus affecting their quality.
[0004] Therefore, a pipe grinding device for hypotube production is proposed. Utility Model Content
