[0001] This utility model relates to the field of cleanliness testing devices, specifically a surface cleanliness testing device for shape memory alloy bone plates. Background Technology

[0002] Shape memory alloy bone plates are medical implants made of shape memory alloys, primarily used for fracture fixation and repair. Compared to traditional metal bone plates, shape memory alloy bone plates have several unique advantages, such as continuous pressure resistance, self-adaptability, reduced stress shielding, and good biocompatibility. However, during the manufacturing process, specialized testing equipment is required to perform surface cleanliness testing to ensure that the surface cleanliness of the shape memory alloy bone plates leaving the factory meets the factory standards.

[0003] However, current cleanliness testing devices still have some shortcomings. For example, the existing cleanliness testing devices have a relatively complicated angle adjustment process, which means that when the testing head needs to test the side area of ​​the joint plate, it takes a long time to adjust the angle, which interferes with the testing efficiency of the device and thus has certain defects in use.

[0004] Therefore, there is an urgent need to improve this shortcoming. This utility model is to study and improve the existing structural deficiencies and provide a surface cleanliness detection device for shape memory alloy bone plates. Utility Model Content
