1. A surgical robot comprising:
a control device that comprises a memory, and a processor that in conjunction with the memory are configured to implement at least:
a position information calculator that calculates information relating to a distal end position of a treatment instrument used in endoscopic surgery, information relating to a distal end position of an endoscope, and information relating to a pivot point position, the pivot point position being a pivot point around which the treatment instrument pivots;
a first display section that displays a relative positional relationship between a distal end of the treatment instrument and a distal end of the endoscope and a relative positional relationship between the distal end position of the treatment instrument and the pivot point by using a calculation result obtained from the position information calculator; and
a second display section that displays an image captured by the endoscope.
