Abstract: A robot device includes an arm, a force sensor, and an adjustment portion. The force sensor is provided at a front end portion of the arm and has a force detecting portion that detects an externally exerted force. The adjustment portion performs a zero point adjustment by setting a reference point of the force detected by the force sensor based on a detection result by the force sensor. The detection result is obtained when the force detecting portion of the force sensor is in a protected condition. The protected condition is a condition in which no load is applied on the force detecting portion of the force sensor. According to this robot device, a technology for accurately setting the reference point of the force detected by the force sensor can be provided.

Abstract: A medical treatment assisting apparatus includes a multi-joint robot, a position specification unit, an abnormality determination unit, and a control unit. The multi-joint robot has a multi-joint arm in which a plurality of arms are connected through a joint. The position specification unit specifies a treatment position that is the position of a portion of a patient to be subjected to a medical treatment in a real space. The abnormality determination unit determines whether or not a state of the treatment position based on the displacement of the treatment position specified by the position specification unit is in an abnormal state, which is predefined to indicate an abnormality. The control unit performs a safety control which increases the safety of the medical treatment when a determination result of the abnormality determination unit indicates that the state of the treatment position is in the abnormal state.

Abstract: A medical support device includes an arm having a drill attached at a tip part of the arm, a first position obtainer obtaining a representative position of the drill attached to the arm, a second position obtainer obtaining a bury start position, and a controller. The controller controls the arm and applies a burying reaction force to the drill in a burying direction, i.e., a direction from the bury start position to an inside of a implant area, when the representative position of the drill obtained by the first position obtainer is at the inside of the implant area relative to the bury start position.

Abstract: In an apparatus for controlling the positioning of an object having a specified point, a first limiter establishes a movable range of the specified point of the object, and limits movement of the specified point of the object within the movable range. The movable range includes a line connecting the position of the specified point of the object and a target position for the specified point of the object. A second limiter limits change of a specified orientation of the object from increasing an angular difference between the specified orientation of the object a target orientation for the specified orientation of the object.

Abstract: In a machining apparatus, a tool has a specified point for machining a workpiece, and a support supports the tool while a position and an orientation of the specified point of the tool are changeable. A actuator actuates the support to move the tool, and a sensor measures a magnitude and an orientation of force upon the force being applied to the tool. A determiner determines, upon the force being applied to the tool, a target orientation of the specified point of the tool according to the magnitude and the orientation of the force measured by the sensor. The force applied to the tool having an orientation to separate the tool from the workpiece. A controller controls the actuator to move the tool according to the determined target orientation.

Abstract: In an apparatus for controlling the positioning of an object having a specified point, a first limiter establishes a movable range of the specified point of the object, and limits movement of the specified point of the object within the movable range. The movable range includes a line connecting the position of the specified point of the object and a target position for the specified point of the object. A second limiter limits change of a specified orientation of the object from increasing an angular difference between the specified orientation of the object a target orientation for the specified orientation of the object.

Abstract: An image completion system includes a first endoscope for obtaining an operating field image, a second endoscope for imaging the object space in a line-of-sight direction different from that of the first endoscope to obtain a completing image, a first device for measuring separating distances between a reference point and a large number of set points that are set in the object space, a second device for measuring three-dimensional positions of the endoscopes, and an image processing device for obtaining, image information on cutoff regions in the object space that are hidden on the depth sides of surgical instruments by imaging the surgical instruments in the operating field image together with the object space, and for replacing image information on the surgical instruments S in the operating field image with the obtained image information or superimposing the obtained image information onto the image information on the surgical instruments.

Abstract: A mouth opening instrument includes an upper member suitable for attaching on an upper jaw side within the mouth of a patient and a lower member suitable for attaching on a lower jaw side. The instrument further includes a connecting section, a control section, and an input section. The connecting section connects end portions of the upper member and the lower member such that a resistance of opening or closing actions of the upper member and the lower member are controllable. The control section controls the resistance of opening or closing actions of the upper member and the lower member. The input section receives an operating state signal indicating an operating state of a dental treatment device. When the operating state signal indicating an operating state of a dental treatment device is inputted, the closing resistance of the upper member and the lower member is set to be greater than that at a time when the operating state signal is not inputted.

Abstract: In a method and apparatus for supporting dental implantation surgery, a three-dimensional CT image of jaws of an object is acquired. A reference site of the jaws and an implantation position of a gum in the jaws are set in the three-dimensional CT image. The implant is implanted at the implantation position. A three-dimensional optical image of an inside of an oral cavity of the object is then produced. The reference site is positionally set in the three-dimensional optical image through recognition of a shape of the reference site in the three-dimensional optical image. A surgical tool is positionally controlled to the implantation position in the oral cavity, based on i) a relationship between the position of the reference site and the implantation position of the gum in the three-dimensional CT image and ii) the position of the reference site in the three-dimensional optical image.
