At the end of March 2018, the National Medical Device Supervision and Administration Working Conference was held in Shanghai. 

The meeting pointed out: “We must conscientiously implement the decisions and arrangements of the Party Central Committee and the State Council on food and drug supervision, adhere to the people-centered approach, take the initiative and perform duties, so that the quality and safety of medical devices will be greatly improved, and the safety of people’s devices will be effectively guaranteed. ”

In medical device processing applications, traditional processing methods, such as plasma spraying, sintering, electrochemical deposition, etc., are no longer suitable for the processing of biomaterial medical devices due to their high temperature, high acidity, and high alkali processing environment. In comparison, ultrashort pulse laser micromachining has the advantages of cold processing, low energy consumption, small damage, high accuracy, and strict positioning in 3D space, and has good application prospects in medical device processing.

Marking stainless steel surgical instruments is a typical application of laser in the medical device industry. 

Surgical instruments are common medical instruments, and marking is an essential part of their production and manufacturing. 

It is often necessary to mark numbers, letters, QR codes, company names and other information.

Due to the particularity of its use environment, there are very high requirements for marking, and it needs to have excellent properties in many aspects such as anti-corrosion, anti-passivation, and resistance to high-pressure sterilization and cooking.
