Advanced Medical Devices Lab
Machine-translated · View original
A lab for advanced medical devices that applies robotics technology to medicine.
AboutAbout the lab
Creating new medicine with robotics technology.
The Advanced Medical Devices Lab conducts research and development to apply technologies centered on robotics to medicine.
Robotics consists of multiple fields, including mechanisms, sensors, and system integration, and the lab studies each of these elements.
The lab works with physicians, healthcare professionals, medical device manufacturers, and other research institutions to put new technologies to use in new forms of medicine.
It develops devices such as a hand and finger rehabilitation robot that uses a compliant structure, and robotic forceps for surgery.
Key terms
- Compliant structure
- A structure that incorporates deformable parts such as springs into a mechanism and uses their deformation to transmit motion and force
- Minimally invasive surgery
- Surgery that reduces the burden on the patient's body
- Forceps
- A surgical instrument for grasping and handling tissue
- Degrees of freedom
- The number of independent types of motion a robot can perform

ResearchResearch themes
The lab aims to realize new medicine using robotics technology. It studies elements such as mechanisms, sensors, control, and system integration, with the goal of more effective medical applications.
*Illustrative imageCompliant Mechanisms for Hand and Finger Rehabilitation
The lab studies a mechanism for hand and finger rehabilitation that is compact, lightweight, and high in output, using a compliant structure made of stacked springs. Through joint research with ETH Zurich (ReLab) in Switzerland and CAMIT at Kyushu University, it built a prototype that moves the four fingers other than the thumb with a single linear motor.
*Illustrative imageSMOVE Hand and Finger Rehabilitation Robot
The hand and finger rehabilitation device that uses the compliant mechanism developed in the lab is currently at the clinical trial stage. Together with Megwell, a startup originating from Kyushu University, and with Sanmatsu and Teijin Pharma, the lab aims to deliver it as a product as soon as possible.
*Illustrative imageSmall-Diameter 4-DOF Robotic Forceps
A challenge for robots used in minimally invasive surgery is that instrument size and bending radius make it hard to reach deep, narrow areas of the body. The lab built 4-degree-of-freedom robotic forceps in sizes of 2.0 mm and 3.5 mm. It believes that making instruments smaller will make surgery possible even in fields where robotic surgery is not yet common, such as neurosurgery, pediatric surgery, and thoracic surgery.
*Illustrative imageSmart Arm Microsurgery Robot
The robotic forceps developed in the lab were incorporated into Smart Arm, an integrated surgical robot system for microsurgery. The robot arm, user interface, and sensors were developed by multiple research institutions, and the system has succeeded in suturing simulated dura mater.
