Solving Surgical Robotic Challenges
When surgical robotic applications requires precise movements, haptic feedback, low friction movements, and breaking system, Dexter Magnetic’s high-precision magnetics and magnetic assemblies with biocompatible materials and sterilization-ready surgical robotics, enables new surgical techniques that result in better patient outcomes.
Highly Engineered Capabilities for:
- Actuators and Joints:
- Magnets are a core component in robotic joints and actuators, enabling precise and efficient movement.
- Haptic Feedback:
- Magnets are used in haptic feedback devices, allowing surgeons to feel the interaction between surgical instruments and tissues.
- Minimally Invasive Surgery:
- Magnetic couplings can manipulate surgical tools within the body, potentially minimizing incisions and recovery time.
- Electromagnets:
- Used to control the movement of robotic arms and other surgical instruments.
- Brakes:
- Electromagnetic brakes are crucial for maintaining stability and precision during surgical procedures.
- Manipulation:
- In some robotic systems, electromagnets are used to generate magnetic fields for precise manipulation of surgical instruments or even miniature robots within the body.
