Publication number: 20190008367Abstract: This disclosure discloses a surgical system that includes, for example, a patient-side cart (also referred to as a surgical robot) and a console apparatus. The patient-side cart includes an endoscope apparatus that includes three or more endoscope arms. The console apparatus manipulates the patient-side cart. In the endoscope apparatus, for example, feature points of respective images obtained by respective imaging devices of the three or more endoscopes are used to join the respective images together to generate a composite image, and the composite image is displayed on a display screen. The composite image generated from the images in three visual fields to be provided to an operator ensures providing an image in a wide range, and allows the operator to confirm various sites by a visual check during surgery (ensuring an endoscopic surgery while having a large visual field as in a laparotomy) (FIG. 1).Type: ApplicationFiled: September 12, 2018Publication date: January 10, 2019Applicants: NIKON CORPORATION, MEDICAROID CORPORATIONInventors: Tetsuro ISHIKAWA, Masato HAMATANI, Jun NAGATSUKA, Shunji WATANABE, Jiro INOUE, Yasuhiko HASHIMOTO, Hirofumi TANAKA, Yoshiyuki TAMURA, Mitsuichi HIRATSUKA
