Abstract: A biopsy system includes an endoscope having an insertion portion provided with a channel and an active bending section disposed in part of the insertion portion, and a treatment tool. The treatment tool has a sheath capable of being inserted into the channel and a needle tube disposed inside the sheath. The sheath has a distal tube portion including a distal end of the sheath and a proximal tube portion fixed to a proximal end of the distal tube portion and less flexible than the distal tube portion. A connecting portion acting as a boundary portion between the distal tube portion and the proximal tube portion is placed in a proximal side relative to a proximal end of a bending section in a positional relationship in which the distal end of the sheath protrudes from a distal end of the channel and is optically observable by the endoscope.

Abstract: A processing apparatus comprises a processor including hardware. The processor acquires structure data of an organ, acquires an endoscope image from an imager of an endoscope, and acquires an ultrasonic image from a probe of the endoscope. The processor automatically controls a probe position of the endoscope based on the structure data and the distal end position information of the endoscope in a first control mode, and automatically controls the probe position based on the ultrasonic image in a second control mode.

Abstract: The medical system includes a basket treatment tool a processor. The processor determines, one or more of: a first determination, based on a transmissive image including the biliary duct, of whether a size of a gallstone allows the basket treatment tool to remove the gallstone from the papillary orifice, or a second determination, based on a resistance when the basket treatment tool is pulled, of whether the resistance allows the basket treatment tool to remove the gallstone from the papillary orifice; and controls the basket treatment tool to remove the gallstone from the papillary orifice when one or more of the first determination or the second determination determines that the gallstone is removable from the papillary orifice.

Abstract: A system that can include a processor that obtains voice data of a subject. The processor can compare the voice data of the subject with reference normal and abnormal voice data. If the voice data of the subject is abnormal, the processor can generate an abnormal subject voice data that is indicative of differences between the subject voice data and the normal voice data. By comparing the generated abnormal subject voice data with the reference normal and abnormal voice data, the processor can determine what condition the subject may be suffering from and the severity of that condition.
