In the medical device field, high-precision ball screws are widely used in various electro mechanical devices, including surgical robots, medical CT scanners, MRI equipment, and other high-precision medical devices.
With their high precision, high-speed motion, high load capacity, and low friction, high-precision ball screws have become the preferred transmission method in the medical device field.
1. Definition and function of ball screw
1.1 Features
High Precision: Ball screws utilize a ball circulation system to achieve efficient, low-friction linear motion conversion.
High Efficiency: Compared to conventional screws, they offer higher transmission efficiency, typically exceeding 90%.
Long Life: Special materials and surface treatment technologies ensure long-term, stable operation.
1.2 The role in the medical industry
Precision Positioning: Provides precise position control for medical devices, meeting the stringent precision requirements of surgical robots and other applications.
Smooth Motion: Ensures device stability during operation, reducing vibration and noise.
Reliability: Maintains long-term, trouble-free operation in demanding working environments.
2. Product classification and working principles in the medical field
2.1 Application of Ball Screw in Surgical Robots
Used in arm joints to achieve multi-degree-of-freedom motion.
Working in conjunction with servo motors, it ensures precise movements.
Surgical robots are currently the most widely used medical robots. They offer high precision, high stability, and a seamless surgical feedback transmission system, enabling surgeons to perform more complex surgeries with minimal injury, significantly improving surgical success rates. High-precision ball screws, as key transmission components in surgical robots, provide high-speed, high-precision rotational control, meeting the precise operation requirements of surgical robots and ensuring surgical success.
2.2 Application of Ball Screw in Medical Imaging Equipment
The X- and Y-axis motion platforms in CT scanners.
The patient bed in magnetic resonance imaging (MRI) equipment is raised, lowered, and translated.
Medical CT scanners are an indispensable piece of medical equipment in modern medicine.
High-precision ball screws are one of the core components of medical CT scanners. They provide high-precision motion control at the thousandth-of-a-millimeter level, enabling them to quickly complete complex scanning procedures, accurately diagnose conditions, and provide crucial insights for doctors.
Magnetic resonance imaging (MRI) is a non-invasive imaging method commonly used to examine lesions in human organs, tissues, and structures.
High-precision ball screws are primarily used in MRI systems to control the motion of the scanning platform.
Their high precision and high load capacity provide a stable motion platform, ensuring accurate and stable scanning.
