Riverfield is currently developing a surgical assist robot with a force feedback function.
When surgeon and assistant surgeon perform on their best, the best surgical outcome can be achieved.
We realized the surgial robot with force feedback in a small size that can unleash the potential of both surgeons and assitans surgeons.
Some of the products introduced here include ones that have not yet been approved under the Pharmaceuticals and Medical Devices Act.
Such products may not be sold or granted in any form. The information contained herein is subject to change as it contains information that is still under development.
Conventional surgical assist robots rely solely on visual information obtained from camera images. This product, however, is equipped with a system that estimates the three forces of forceps, “gripping force = grasping force,” “touching force = tactile force,” and “pulling force = traction force,” from control information and feeds them back to the remote control interface.
This product converts the “three force senses” obtained from forceps into electrical signals.
Based on the signal, the sense of force is fed back directly to the operating handle, allowing the surgeon to perform surgery while feeling the sense of force.
The control unit of this product has two monitors: a Main monitor that displays images from the endoscope and a Navigation monitor that displays the sense of force and other information.
The Main monitor also supports 3D display, and stereoscopic viewing is possible by wearing special 3D glasses.
We strive to provide a more realistic view during the procedure by seeing the endoscopic images in stereoscopic viewing.
It is also possible to switch between 2D and 3D displays by changing settings.
In addition to the Main monitor that displays images from the endoscope, the control unit of this product is equipped with a Navigation monitor that displays the sense of force obtained from the forceps and other information.
The Navigation monitor displays force senses intuitively using gauges and bar graphs as well as quantitative values (Newton number) to support the procedure from both a numerical and sensory perspective, making it possible to provide operating information to physicians and nurses other than the primary surgeon.
Pneumatic drive is more compact than conventional electric drive, which made this product lightweight and compact, with a height of approximately 150 cm and weight of approximately 450 kg. This allows it to be used in smaller, non-specialized operating rooms and to be moved between operating rooms and within a facility for more flexible operation.
