Surgical instruments—such as laparoscopic tools, endoscopic devices, and surgical robots—require reliable sealing, smooth surfaces, and resistance to repeated sterilization. These instruments are used in sterile clinical environments, and any gaps or rough surfaces can harbor bacteria, leading to infections. Traditional welding methods may leave visible seams, burrs, or gaps, making them difficult to clean and sterilize. DaokeDao plastic laser welding creates seamless, smooth welds that are easy to clean and sterilize, reducing the risk of bacterial contamination. The hermetic seal achieved by laser welding prevents the intrusion of moisture, dust, and bacteria, ensuring the sterility of internal components (such as motors, sensors, and cables). The process supports high-strength medical plastics commonly used in surgical instrument housings, including PC, ABS, and PPS, which are resistant to autoclave sterilization (high temperature and pressure) and chemical disinfectants. The non-contact process avoids surface damage and maintains the smoothness of instrument surfaces, ensuring patient safety during surgery. Our laser systems are designed to meet the strict requirements of medical device manufacturing, with features such as process traceability and quality control. They help surgical instrument manufacturers improve product reliability, enhance patient safety, and meet regulatory standards.
