Diana 7 Med

Diana 7 Med delivers Agile Robots’ force-control technology in a medical-grade 7-degree-of-freedom robotic arm platform. With torque sensors integrated into all seven joints achieving 0.5N force sensitivity, this system serves as a foundational component for surgical robot manufacturers and healthcare institutions deploying robotic assistance across multiple specialties.

Product Overview

Building upon the Diana 7 industrial platform, Diana 7 Med adapts Agile Robots’ core force-sensing technology for healthcare environments. The system functions primarily as an OEM platform, enabling surgical robot developers to integrate sophisticated force-feedback capabilities without developing fundamental arm technology from scratch.

The platform’s heritage traces to the German Aerospace Center (DLR), which pioneered force-controlled robotics through its LWR series. This technological lineage positions Diana 7 Med among the most sensitive collaborative robotic arms available for medical applications.

Key Features

7-Axis Force Sensing: High-precision torque sensors in all seven joints enable collision detection, compliant motion, and force-feedback during tissue interaction. Force sensitivity reaches 0.5N, comparable to human tactile perception.

Null-Space Control: The 7-DOF redundant kinematic design allows the arm to navigate around obstacles while maintaining end-effector position, particularly valuable in confined surgical fields where multiple instruments must coexist.

AgileCore Integration: The robotic arm connects to Agile Robots’ AI-driven operating system, enabling rapid skill programming through demonstration rather than conventional coding approaches.

Compact Design: Anthropomorphic kinematics and lightweight construction (under 20 kg arm weight) enable integration into existing surgical suites without major infrastructure modifications.

Technical Specifications

Designed for surgical and rehabilitation OEM integration, Diana 7 Med provides 7-DOF with 0.5N force sensitivity, 923mm reach, ±0.05mm repeatability, IP54 protection, and under 20kg arm weight.

Clinical Applications

Diana 7 Med supports diverse medical scenarios through its combination of precision positioning and force compliance:

Orthopedic Surgery: Partners with companies like Tinavi to provide force-controlled positioning for bone drilling, implant placement, and joint replacement procedures.

Neurosurgery: Collaborates with Remebot for stereotactic procedures requiring sub-millimeter accuracy and stable instrument holding.

Minimally Invasive Surgery: Laparoscopic and endoscopic applications benefit from the arm’s ability to maintain steady instrument positioning while responding to tissue contact forces.

Diagnostic Procedures: Ultrasound probe positioning and biopsy needle guidance use the force-feedback capabilities for consistent contact pressure.

Rehabilitation Therapy: The X-SPA solution builds upon Diana 7 Med for physical therapy applications, automating massage and exercise assistance with force-modulated movements.

Regulatory Status

Diana 7 Med operates primarily as an OEM component integrated into partner companies’ medical devices rather than as a standalone Class II/III medical device. Regulatory clearances for end-use medical applications are obtained by integrating partners (e.g., Tinavi’s TiRobot, Remebot’s Remebot system).

Integration Partners

The platform has been adopted by leading Chinese surgical robot manufacturers:

• Tinavi (天智航): Orthopedic surgical robot systems
• Remebot (柏惠维康): Neurosurgical robot systems
• Multiple tertiary hospitals: Direct deployment for rehabilitation and therapy applications

Frequently Asked Questions

Does Diana 7 Med require separate NMPA registration?

Diana 7 Med typically integrates into partner companies’ medical systems that obtain their own regulatory clearances. The arm itself may not require independent medical device registration when supplied as an OEM component, though specific regulatory pathways depend on the intended use configuration.

What distinguishes Diana 7 Med from industrial Diana 7?

The medical variant incorporates enhanced biocompatibility considerations, cleanroom-compatible materials, and validation documentation supporting healthcare deployment. Core force-control technology remains identical to the industrial version.

Can Diana 7 Med be used for autonomous surgery?

The system is designed for surgeon-controlled or supervised operation rather than autonomous surgical execution. Force feedback provides real-time tissue interaction awareness while maintaining human oversight of surgical decisions.
