Assignee: HUTOM INC.
Field: Medical technology (Instruments)
Classification: CPC A  G | IPC A  G

Claim 2:
3. An optimal entry position providing method of a surgical instrument 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;
performing simulation using an operation unit of a surgical instrument having an arm part and an operation unit, for performing a surgical operation on a surgical target site of the surgical subject in the virtual body model; and
calculating, based on the simulation result, an optimal entry position on a body surface of the surgical subject, to which the surgical operation performed by the operation unit is capable of being applied in an inner body space of the surgical subject.
