CUVIS-joint

Optimal surgical planning and precise cutting

CUVIS-joint

is a cutting-edge surgical robot system that improves the completion of artificial joint surgery with optimal surgical planning and precise cutting.

With optimal tracking sensors and self-developed surgical planning CUVIS-joint helps patients that are in need of artificial knee surgery.

Why CUVIS-joint is good?

  • Point. 01

    Surgical Planning & Execution Based on 3D CT Analysis

    Surgical Planning & Execution Based on 3D CT Analysis

    Precisely analyzes the patient's bone morphology based on pre-operative 3D CT images and accurately predicts femoral (98.9%) and tibial (100%) implant sizes.1

    Precise Bone Resection

    The robotic arm performs precise bone resection within a 1mm error margin (98% rate) within the planned range.1

    Sophisticated Angle Control

    Maintains the cutting angle error (RMS) below 1 degree, ensuring that simulation results are perfectly reproduced in the actual operating room.2

  • Point. 02

    Optimal Soft Tissue Balance and Alignment

    Real-time Gap Balancing

    Checks and adjusts the gap balancing of the medial and lateral knee in real-time during surgery to support achieving ideal balance.3 4

    Functional Alignment

    Goes beyond simply straightening the bone by identifying the optimal rotational alignment reflecting the patient's specific rotational axes (TEA, PCA).5 6

    Joint Line Restoration & Soft Tissue Preservation

    Restores the anatomical position by maintaining pre- to post-operative joint line height changes at an average level of 1.65mm, and reduces the frequency of unnecessary soft tissue releases.7 8
