Medical and Welfare Support Robotics Lab (Kawamura Lab)
Machine-translated · View original
A lab that researches the design and evaluation of robots that support medicine and welfare.

AboutAbout the lab
Designing easy-to-use assistive devices from the very start.
The Kawamura Lab researches robot technologies that support treatment in the field of medical and welfare engineering.
Its goal is "developing easy-to-use medical and welfare support devices and establishing methods to evaluate them."
In designing surgical robots, the lab develops a simulation that reproduces the surgical space based on basic data such as physicians' manual techniques, and uses it to verify the requirement specifications before development.
The lab is also developing robots to support WaFLES, a laparoscopic surgery newly established at Chiba University that is performed with the body cavity filled with isotonic solution.
Key terms
- Single-port surgery
- Surgery performed through just one opening in the body. Surgical instruments tend to interfere with each other.
- Isotonic solution
- A liquid with the same osmotic pressure as body fluids. It is less likely to damage cells.
- Outer tube (cannula)
- A tubular channel inserted into the body, through which surgical instruments such as forceps and endoscopes are passed.
ResearchResearch themes
The lab develops robot technologies that support treatment in medical and welfare fields. For surgical robots, it believes consistent verification is needed, from the design stage through to predicting how the robot will perform once it is in use.
*Illustrative imageSurgical space reproduction simulation
Because there are multiple cases and treatment methods, devices must be designed from the very start of development with the target cases in mind. The lab has developed a surgical space reproduction simulation that integrates a mathematical simulator with an actual operating-input system, and also works on device design for pediatric surgery.
*Illustrative imageRobot systems to support WaFLES
WaFLES is expected to be performed as single-port surgery, and its challenges are poorer operability caused by interference between surgical instruments, and an unstable surgical field caused by organs floating due to buoyancy. The lab is developing a cannula-type manipulator that secures the surgical space, along with a sensing system for it.
