Abstract

The invention discloses a laser surface treatment method for an interventional medical device, and relates to the application field of laser technologies. According to the laser surface treatment method, laser scanning is mainly used, micro-structures capable of reducing friction force between the interventional medical device and a human body channel when the interventional medical device is in the human body channel is formed on the surface of the interventional medical device, surface friction is reduced, a clad layer used for reducing friction force is prevented from being formed on the surface of the interventional medical device, the risk of harms caused by clad layer falling to a patient is removed, and an interventional surgery is safer and more reliable.

Description

technical field [0001] The invention relates to the technical field of laser applications, in particular to a laser surface treatment method for interventional medical devices. Background technique [0002] In the prior art, the interventional medical device needs to move in the passage of the human body (such as blood vessels, or various intestinal tracts) during operation. In order to reduce the friction between the interventional medical device and the passage of the human body, it is generally necessary to coat the surface of the interventional medical device with a coating to improve the mobility and operability of the device in the passage of the human body. However, this coating adds an additional risk of the possibility of the coating peeling off. The peeled coating will remain in the human body passage, and even cause the death of the patient in severe cases. Contents of the invention [0003] The technical problem to be solved by the present invention is: how t...
