1. An optimized surgical instrument providing method performed by a computer, the method comprising:
obtaining a virtual body model generated to be matched with a body state of a surgical subject;
obtaining inner body information and body surface information of the surgical subject,
wherein the inner body information includes information about a placement state of organs located in an inner body space of the surgical subject, and the body surface information includes body surface shape information of the surgical subject, and
wherein the inner body information and the body surface information are obtained from the virtual body model generated by applying medical image data for a patient to a pneumoperitoneum formation algorithm that is an algorithm for generating 3D modeling data in a normal state into 3D modeling data in a pneumoperitoneum state;
simulating a surgical operation within the virtual body model, using a surgical instrument having an arm part and an operation unit;
calculating, based on the simulation result, an operation range of the arm part,
wherein the operation range of the arm part is a range in which the arm part is capable of being operated depending on a motion of the operation unit without affecting the organs of the surgical subject, based on the inner body information and the body surface information of the surgical subject; and
determining, based on the calculation result, a structure of the surgical instrument by determining a length of the arm part, an existence of a joint part that connects the operation unit to the arm part, and motion information of the joint part depending on a placement relationship of the joint part with the operation unit.
