At the end of March 2018, the National Medical Device Supervision and Management Work Conference was held in Shanghai. The meeting pointed out: "We must conscientiously implement the decisions and deployments of the Party Central Committee and the State Council on food and drug supervision work, adhere to the people-centered approach, take the initiative, and perform duties with due diligence. The quality and safety of medical devices will be greatly improved, and the safety of people's use of equipment 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 the high temperature, high acid, and high alkali processing environment. In contrast, ultrashort pulse laser micromachining has the advantages of cold machining, low energy consumption, less damage, high accuracy, and strict positioning in 3D space. It has a good application prospect in medical device processing.
Marking on stainless steel surgical instruments is a typical application of lasers in the medical device industry. Surgical instruments are common medical devices. Marking is an essential part of its manufacturing. It is often necessary to mark numbers, letters, two-dimensional codes, company names and other information. Due to the particularity of its use environment, it has high requirements for marking, and it needs to have excellent performance in many aspects such as corrosion resistance, passivation resistance, and autoclave resistance.
Laser micromachining has the characteristics of ultra-fast and ultra-precision, and has unique advantages in the processing of medical devices, especially for micro-machining of materials with good biocompatibility, which has an irreplaceable role.
Laser coding for paper packaging boxes, laser coding for plate-filled drugs, laser coding for PET plastic bottles, fine marking of surgical instruments
Medical packaging materials cutting, medical equipment parts cutting, such as various
Cutting of sheet metal and pipes, cutting of various high-hard and brittle alloy materials, etc.
Heart rate adjuster head on medical equipment, stainless steel needle tube, etc.
Laser stitching, butt joints, lap joints and spot welding, etc.
Laser micromachining has the characteristics of ultra-fast and ultra-precision, and has unique advantages in the processing of medical devices, especially for micro-machining of materials with good biocompatibility, which has an irreplaceable role. The system summarizes several new applications of laser micromachining technology in the field of biomedicine, focusing on the micromachining of the surface structure of biomaterials, the microstructure preparation of medical components and vascular stents, and the rapid prototyping of three-dimensional biological tissues, and further points out the existing laser Limitations and development trends of micro-processing for preparing biomedical materials.
Medical products are products that come into direct contact with people, and are closely related to people's health and life safety. The production standards of medical products are very strict, and the key components need to be marked with persistent and traceable marks. Through this mark, the production time, location, production batch number, manufacturer and other information of the product can be found. In addition, the medical industry pays great attention to product safety and hygiene, and ultrashort pulse laser marking technology has the advantages of cold processing, low energy consumption, small damage, high accuracy, strict positioning in 3D space, and smooth marking surface that is not easy to breed bacteria. , Fully meets the medical industry's requirements for medical product marking, and now laser marking technology has penetrated into the medical industry.
In summary, the application of laser technology has higher precision, faster efficiency, more precise processing, lower carbon and energy-saving processes, higher yield, lower purchase and operating costs.
