摘要： To provide a motion training apparatus capable of appropriately continuing motion training while ensuring safety even when an operation unit is deviated from a target trajectory in a passive training mode. A controller of a motion training apparatus detects, by a force sensor, a force Fx in an X-axis direction and a force Fy in a Y-axis direction acting on an operation unit movable in an XY plane, and controls an X-axis direction drive motor and a Y-axis direction drive motor so that, when a magnitude of a resultant force F0 of the forces Fx, Fy is within a predetermined range, the operation unit moves along a predetermined trajectory, and when the resultant force F0 exceeds the predetermined range, the operation unit moves in accordance with a first speed vector having a magnitude for directing the operation unit from a current position to a subsequent target position.

摘要： It was difficult to create a thin bio sample embedded in an embedding material without using an expensive microtome. The present invention provides a medical device having a space for assisting in the embedding of a bio sample in an embedding material, the medical device being provided with a cover part and a base part having a recessed section in which the space is created by covering the cover part, wherein the base part is provided with a flow passage having an inlet section that is in fluid communication with the space, and the flow passage is configured such that when a force is applied to the medical device so that the volume of the space decreases, the embedding material flows out while preventing a positional misalignment of the bio sample inside the embedding material.
