Carbon steel knurled pin for milling and fixed shaft CNC processing - precision hardware

Medical AI

Industry Core: Medical AI is the in-depth integration of AI technology and the medical industry, covering surgical robots, intelligent hospital beds, AI imaging equipment, intelligent monitoring equipment, etc., and is applied in medical scenarios such as hospitals, clinics, and research institutions. The industry has extremely high requirements for the biocompatibility, sterility, precision, non-magnetism, and compliance of hardware components, and the structure and function of different medical equipment vary greatly, with prominent non-standard customization needs, and must strictly comply with relevant medical industry standards (ISO 13485).

AI Scenarios: Surgical robots (AI-assisted surgery, precise operation, minimally invasive treatment), intelligent hospital beds (AI health monitoring, automatic adjustment, nursing assistance), AI imaging equipment (AI diagnosis of CT, MRI, ultrasound imaging), intelligent monitoring equipment (AI heart rate monitoring, blood pressure monitoring, abnormal early warning). These scenarios all require hardware components to have the characteristics of biosafety, sterile compliance, high precision, and no interference, ensuring the safe and precise operation of medical equipment.

Key Hardware Products: Biocompatible fasteners (titanium alloy/Ti6Al4V non-standard screws, 316L stainless steel fasteners), sterile environment hinges (medical-grade hinges, dead-angle-free hinges), anti-bacterial handles (anti-bacterial handles, sterile handles), MRI-compatible non-magnetic hardware (non-magnetic fasteners, structural parts). In addition, it also includes surgical robot joint connectors, imaging equipment fixing parts, monitoring equipment hardware accessories, intelligent hospital bed adjustment hardware and other non-standard customized parts.

Core Functions: Achieve reliable connection of various parts of medical equipment to ensure the stability and accuracy of equipment operation; have biocompatibility to avoid safety hazards such as allergies and infections when in contact with the human body; meet sterility requirements, facilitate cleaning and sterilization, and avoid cross-infection; achieve no interference of MRI and other imaging equipment to ensure the accuracy of AI imaging diagnosis; adapt to the adjustment function of medical equipment to improve nursing efficiency and patient experience; comply with medical industry compliance standards to ensure the safety and reliability of equipment.

Selection Notes & Processing Advantages (Machining/Cold Heading):

1. Biocompatibility and Cleanliness for Medical Safety Needs: For equipment such as surgical robots and intelligent hospital beds, some hardware parts need to be in direct or indirect contact with the human body, which must have good biocompatibility, and the surface must be free of dead angles and easy to clean, meeting sterility requirements. We select biocompatible materials such as titanium alloy (Ti6Al4V) and 316L stainless steel, and achieve a hardware surface Ra≤0.8μm through precision machining (Swiss-type lathes, CNC machining centers) combined with electropolishing technology, which is free of burrs and dead angles, easy to clean and sterilize, and avoids cross-infection caused by dirt accumulation. For non-standard fasteners of surgical robots, a combination of cold heading and machining processes can be used to ensure the density and biocompatibility of the material, and at the same time, the dimensional accuracy is accurately controlled to meet the high-precision connection needs of surgical equipment, complying with the ISO 13485 medical industry standard.

2. MRI Non-Magnetic Customization to Avoid Imaging Interference: MRI imaging equipment operates in a strong magnetic field environment. Ordinary hardware parts (such as carbon steel) will generate magnetic interference, affecting the accuracy of imaging diagnosis, so non-magnetic hardware parts must be selected. We have the ability to customize and process non-magnetic hardware parts, select high-conductivity non-magnetic stainless steel, aluminum alloy and other materials, and strictly control the magnetic permeability of the material (≤1.005) through cold heading and machining processes to ensure that the hardware parts do not generate magnetic interference in a strong magnetic field environment, ensuring the accuracy of AI imaging diagnosis. At the same time, we can customize and process the fixing parts and connecting parts of MRI equipment to accurately adapt to the structural needs of the equipment, taking into account non-magnetism and high strength.

3. High-Grade Surface Treatment for Sterilization Needs: Medical equipment needs to be subjected to high-temperature and high-pressure sterilization (134℃/30min) regularly. Ordinary surface treatment is easy to fall off and rust, affecting the service life and sterility of hardware parts. We support special surface treatments such as medical-grade passivation, nickel plating, and electropolishing. The thickness and uniformity of the coating are accurately controlled through machining to ensure that the surface treatment layer is not easy to fall off and corrosion-resistant, can withstand multiple high-temperature and high-pressure sterilizations, does not rust, and does not produce harmful substances, meeting the long-term sterile use needs of medical equipment. At the same time, we can provide surface treatment test reports according to customer needs to ensure compliance with medical industry requirements.

4. High Precision and Safety for Surgical Precision Needs: Surgical robots have extremely high requirements for the precision of hardware parts. The preload error of fasteners must be ≤±5% to avoid loosening during surgery, which affects surgical safety and precision. We accurately control the dimensional accuracy and thread accuracy of non-standard fasteners through precision machining equipment, and ensure the stable preload of fasteners with customized anti-loosening structures, with errors controlled within the required range. For the joint connectors of surgical robots, machining is used to accurately control the fit accuracy of the shaft and hole, ensuring the flexibility and accuracy of joint movement, helping the precise operation of AI-assisted surgery. At the same time, we can quickly custom-develop non-standard hardware parts according to the model of the surgical robot to meet the equipment iteration needs.
