Virtual Reality Training for Surgeons Developed in Germany

Revolutionary Haptic Feedback System Enhances Surgical Education

GERMANY: A consortium of German institutions has unveiled an innovative virtual reality (VR) system designed to revolutionize surgical education. The VIRTOSHA project, led by MindPort GmbH in collaboration with the University Hospital Bonn (UKB), TH Köln, and Haption GmbH, aims to create a VR training environment that provides realistic tactile feedback for surgical procedures.

Simulating the Surgical Experience

At the heart of this groundbreaking technology is a sophisticated simulation system that replicates the feel of different tissues and bones during surgical interventions. PD Dr. Kristian Welle, (pictured on the right) a senior physician at UKB, explains the significance of this development:

“During their training, future surgeons need to experience what operations feel like and train their fine motor skills. Therefore, we are developing a new VR training tool that enables lifelike interaction with the tools. We are designing a drilling and screwing simulation with haptic feedback robotic arms and will implement the characteristics of different types of tissue.”

This approach allows trainees to experience the resistance encountered when drilling into bones or manipulating soft tissues, providing a level of realism previously unattainable in virtual training environments.

Customizable Training Scenarios

One of the most exciting features of the VIRTOSHA system is its ability to create diverse training scenarios. By analyzing real operations, the team has developed software that can adjust tissue and bone properties to simulate a wide range of patient conditions. Prof. Björn Krüger, (pictured on the left) head of the “Personalized Digital Health and Telemedicine” research group at UKB, highlights the importance of this feature:

“We use software to design different scenarios where tissue and bone properties can be adjusted to simulate different patients. A realistic representation of the tissues and bones as well as the precise integration of hand movements are crucial for the real feeling in the VR environment.”

Empowering Surgeons with Content Creation

In a novel approach to surgical training, the VIRTOSHA project incorporates an authoring tool that allows surgeons to create and update training content. David Lähner, founder and CEO of MindPort, describes this innovative aspect:

“Using an integrated authoring tool, surgeons will be able to create new content and update existing content themselves. This allows many more different cases to be covered. Our long-term vision is that a ‘digital twin’ of the patient can be used to practice in virtuality before the real operation begins.”

This feature not only expands the range of training scenarios available but also ensures that the system can be continually updated to reflect the latest surgical techniques and technologies.

Implications for Medical Training and Patient Care

The potential impact of this VR training system extends beyond initial surgical education. PD Dr. Kristian Welle notes that “This approach is not only exciting for the training of our new colleagues, but will also greatly simplify the introduction of new implants.” This suggests that the VIRTOSHA system could play a crucial role in helping experienced surgeons adapt to new medical technologies and procedures.

Collaborative Effort and Funding

The VIRTOSHA project represents a collaborative effort between academic institutions and private companies, combining expertise in medical practice, computer science, and haptic technology. Funded with 1.5 million euros as part of the Gesünder.IN.NRW innovation competition, the project is set to run for three years, promising continuous development and refinement of this cutting-edge training tool.

As virtual reality continues to transform medical education, the VIRTOSHA project stands at the forefront, offering a glimpse into the future of surgical training. By providing a risk-free environment for practice that closely mimics real-world scenarios, this technology has the potential to significantly enhance the skills of future surgeons and, ultimately, improve patient outcomes.
