1. Minimally Invasive Surgical Devices

(1) Surgical Robots

Our micro steel balls are utilized in the joints and transmission systems of surgical robots, enabling precise and sophisticated operations. Their small size and high load-bearing capacity allow surgical robots to perform complex surgical procedures with enhanced accuracy.

(2) Laparoscopes and Endoscopes

Micro steel balls are integral to the rotational components and probe control systems of endoscopic devices. They ensure stable rotation of cameras and other instruments, assisting surgeons in achieving accurate positioning during minimally invasive procedures.

2. Medical Injection Devices

(1) Infusion Pumps and Injectors

Micro steel balls serve as critical components in valve control systems, ensuring the precise regulation of liquid flow in infusion pumps, insulin pumps, and other drug delivery systems. This guarantees accurate and consistent medication administration to patients.

3. Artificial Joints and Orthopedic Implants

Micro steel balls play a pivotal role in the design and functionality of orthopedic implants, particularly in artificial joints. They provide the necessary flexibility and wear resistance required for such applications.

(1) Artificial Knee and Hip Joints

In artificial joint systems, micro steel balls are employed in the rotational and sliding components to ensure durability and smooth joint motion.

(2) Bone Fracture Fixation Devices

Micro steel balls are used in bone fixation devices for precise adjustments and stability, facilitating the alignment and immobilization of fractured bones.

4. Dental Instruments

Micro steel balls are extensively used in the dental field, particularly in dental tools such as drills and other rotating devices.

(1) Dental Drills and Rotational Tools

Micro steel balls are incorporated into the transmission systems of dental drills, enhancing rotational efficiency and enabling effective cutting and removal of diseased tooth material.

5. Heart Valves and Pacemakers

(1) Mechanical Heart Valves

In mechanical heart valves, micro steel balls are a vital part of the valve system, ensuring unidirectional blood flow and preventing backflow.

(2) Pacemakers

Micro steel balls are utilized in the mechanical transmission components of pacemakers, aiding in the precise control of pulse signal transmission to maintain normal heart rhythms.

6. Medical Diagnostic Equipment

(1) Magnetic Resonance Imaging (MRI) Devices

Micro steel balls are employed in the control and positioning mechanisms of MRI systems, facilitating precise power transmission and accurate equipment alignment. Non-magnetic steel balls are used to prevent interference with imaging quality.

(2) Ultrasound Diagnostic Devices

In ultrasound diagnostic equipment, micro steel balls are used in transmission devices and automated control components, ensuring precise positioning and stable operation of the system.
