Latest Patents

Among his latest patents is a spool valve design. This invention features a spool that is slidably located in a slide hole of a first housing. A second housing forms a servo chamber that is coaxial with the slide hole. A sleeve is also slidably located in the servo chamber, and a nut is fixed to a piston that is fitted in the sleeve. An electric motor rotates a screw shaft that is screwed with the nut. The second housing includes an input port and a drain port, while a first pressure chamber communicates with the input port. In a balanced state, forces applied to the sleeve from both sides are equal, blocking the second pressure chamber from the input and drain ports by the piston. When the piston shifts from this balanced state, the second pressure chamber can communicate with either the input port or the drain port.

Another significant patent involves a method of controlling a surgical system. This system is designed to easily acquire an image of the tip end portion of a surgical instrument attached to a manipulator arm, even when the instrument is bent. The surgical system includes manipulator arms, a manipulation unit, and a controller. The first manipulator arm holds a surgical instrument with a bendable portion, while the second manipulator arm holds an endoscope assembly that includes a bendable portion and a camera at its tip. The method controls the endoscope assembly to bend in accordance with the bending of the first surgical instrument based on an operating command.
