  • Publication number: 20210030476
    Abstract: A medical system and an operating method of a medical system are disclosed. The medical system includes: an endoscope; a controller that can operate the endoscope and generate a display image from a captured image; and a display for displaying the display image. The controller can record a model of an organ of concern generated in a preoperative plan, extract feature points in the model, extract a distance between each feature point and a reference position set in the model before surgery, extract corresponding points in the display image, and associate a first coordinate system of the model with a second coordinate system of a display space, based on the feature and corresponding points, to set a path for the endoscope to move such that a region of interest in the organ of concern corresponding to the reference position is displayed in the display image.

  • Patent number: 10450431
    Abstract: Embodiments of the invention relate to a poly(meth)acrylimide film and a method for manufacturing such a film. At least one embodiment provides a poly(meth)acrylimide film that has (i) a total light transmittance of over 90% and (ii) haze of 2.0% or less. This film preferably has retardation of less than 50 nm. The method for manufacturing this film includes the following steps: (A) using a device provided with an extruder and a T die, a poly(meth)acrylimide molten film is continuously extruded from the T die; and (B) the poly(meth)acrylimide molten film is loaded by being fed between a rotating or circulating first mirrored-surface body and a rotating or circulating second mirrored-surface body, and then the film is pressed. During these steps, (C) the surface temperature of the first mirrored-surface body is in the range 100-200° C., and (D) the surface temperature of the second mirrored-surface body is in the range 20-200° C.

  • Publication number: 20190175292
    Abstract: Embodiments of the technology disclosed herein is directed to a medical manipulator capable of detecting an instant when a tip of the medical manipulator is unexpectedly separated from a body tissue and thus avoid making contact with surrounding body tissues. The technology disclosed eliminates the needs for providing a force sensor located on the tip of the medical manipulator. The medical manipulator includes a movable unit at one end and an electric motor, a control unit, and an operation input unit at opposed end thereof. The movable unit includes a treating unit for treating the body tissue. The electric motor is configured to operate the movable unit. The electric motor includes a current sensor or a torque detecting unit for detecting the torque of the motor. The control unit includes a torque reducing unit for reducing the torque transmitted to the movable unit from the electric motor.

  • Patent number: 10112369
    Abstract: Embodiments of the invention provide a transparent poly(meth)acrylimide-based resin multilayer film exhibiting excellent surface smoothness, transparency, outer appearance, and resistance to puchability. According to at least one embodiment, there is provided a method for producing said transparent multilayer film, in which the transparent multilayer film in which a first poly(meth)acrylimide-based resin layer (?1), an aromatic polycarbonate-based resin layer (?), and a second poly(meth)acrylimide-based resin layer (?2) are directly laminated in said order, and in that the total light transmittance exceeds 90% and the haze is 2.0% or lower. The transparent multilayer film is produced by continuously coextruding, from a T die, a molten film of the transparent multilayer film in which the aforementioned layers were directly laminated in the aforementioned order, and by supplying and then pressing the molten film between a first mirror body that has a surface temperature between 100 and 200° C.
