Publication number: 20230363777Abstract: 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.Type: ApplicationFiled: May 11, 2023Publication date: November 16, 2023Applicant: OLYMPUS CORPORATIONInventors: Genri INAGAKI, Masayasu CHIDA, Yuji SAKAMOTO, Makoto ISHIKAKE, Seiichiro SAKAGUCHI, Shohei HEMMI
