Description

Technical Field

[0001] The utility model relates to a device for detecting the curvature of a medical sheath tube, and belongs to the technical field of medical sheath tube detection. Background Art

[0002] Medical sheaths are a type of therapeutic device widely used in vascular interventional surgeries. Their purpose is to establish a delivery channel between the patient's site and the outside world, so that doctors can directly apply different therapeutic equipment, instruments, drugs, etc. to the patient's site. For example, a camera can be used to obtain real-time images of the patient's site. In actual use, since the patient's site may be located in different parts of the patient, the shape, structure, and size of the medical sheath are also different. Therefore, the curvature test of the medical sheath is of great significance in ensuring the flexibility of the medical sheath and reducing vascular damage.

[0003] Existing testing of the curvature of medical sheaths often involves post-testing and repairing finished products. The repair process often requires staff to apply external force to the medical sheaths. Due to the different degrees of curvature of medical sheaths, it is difficult to achieve uniformity in the applied external force.
