Abstract: The disclosed technology is directed to a treatment instrument having a vibration generating device and a handle for operation. The vibration generating device comprises a housing and a generator including a transducer disposed within the housing. The transducer generates vibration by using electric energy and a first electric contact disposed on the housing. A connector is rotatable about a predetermined rotational axis with respect to the housing of the generator. A coupler is disposed in the connector and having a second electric contact rotatable about the predetermined rotational axis with respect to the first electric contact in a state in which an electric connection of the second electric contact to the first electric contact is maintained. The connector further includes a conductive member forming a part of an electric path of a current that flows based on an operating input at an operating member provided on the handle.

Abstract: A control device includes: a power source configured to supply a high frequency power to a treatment instrument configured to treat a living tissue; a detecting circuit configured to sequentially detect a phase difference between a voltage and a current of the high frequency power supplied to the treatment instrument; and a processor configured to control operation of the power source, the processor being configured to sequentially calculate a variation of the phase difference detected by the detecting circuit, compare the calculated variation of the phase difference with a first threshold set for a variation of a phase difference, and perform reduction processing to reduce output of the high frequency power to be supplied to the treatment instrument when it is determined that the calculated variation of the phase difference is equal to or smaller than the first threshold.

Abstract: A method of finding a set of corresponding points in images to be registered. According to the method, an input unit of the system receives a first user input, indicative of a reference point in an intraoperative image. A processing unit sets a reference area surrounding the reference point and converts the image data points in the reference area to a intraoperative point cloud. The input unit receives a second user input, indicative of a candidate point in a preoperative image. The processing unit sets a search area surrounding the reference point and converts the image data points in the reference area to a preoperative point cloud. By comparing geometric feature descriptors of the image data points, the processing unit finds a target point in the preoperative image corresponding to the reference point and defines the points as set of corresponding points.

Abstract: An eccentricity measurement method includes first to eighth steps. In the first step, an eccentricity measurement device for relatively linearly moving an optical image for measurement to an optical unit under test and acquiring an image on an observed surface orthogonal to a reference axis defined by a relative movement trajectory of the optical image is provided. In the second step, a position of a reference point is identified. In the third step, an optical unit under test is arranged. In the fourth step, the optical image is projected onto a projection position on the reference axis and a reflected image reflected on the surface under test is formed at an observation position where a distance from the projection position is a set value L. In the fifth step, a measurement image is acquired. In the sixth step, an image of the reflected image is identified. In the seventh step, an amount of positional deviation of the image of the reflected image is measured. In the eighth step, an amount of eccentricity of the apparent spherical center of the surface under test is calculated.

Abstract: An image processing apparatus includes an inference part which is capable of inference by using a first inference model for finding of a specific target object and by using a second inference model for discrimination about the specific target object and a control unit to which a first picked-up image obtained under a first image pickup condition and a second picked-up image obtained under a second image pickup condition different from the first image pickup condition can be inputted and which performs control such that in a case where the first picked-up image is inputted, the inference part is caused to execute inference by using the first inference model, and in a case where the second picked-up image is inputted, the inference part is caused to execute inference by using the second inference model.

Abstract: An endoscope system includes an endoscope, a robot arm that moves the endoscope, and a controller that controls the endoscope and the robot arm. The controller is configured to receive an image acquired by the endoscope, calculate a first orientation of a first treatment tool in a first image, which is the image received at a given point in time, calculate a second orientation of a second treatment tool in a second image, which is the image received a predetermined time before the first image, calculate a difference between the first orientation and the second orientation, determine whether or not the endoscope follows movement of the first treatment tool by comparing the difference with a threshold value, and in response to determining that the endoscope follows the movement of the first treatment tool, generate a command for the robot arm for making the endoscope follow the first treatment tool.
