Method and apparatus for controlling surgical instrument

A connector formed to connect between a handle and an end tool through a first connection member and a second connection member, wherein

• the first connection member includes one end to which a first contact of the end tool is connected and another end to which a third contact of the handle is connected, and
• the second connection member includes one end to which a second contact of the end tool is connected and another end to which a fourth contact and a fifth contact of the handle are connected,
• wherein the first connection member is formed to extend in a direction from the handle toward the end tool,
• wherein the second connection member is formed to extend in the direction from the handle toward the end tool,
• wherein the one end and the another end of each of the first connection member and the second connection member are formed to be inclined with respect to a plane perpendicular to the direction from the handle toward the end tool.

A method of controlling a surgical instrument, the method comprising:

• detecting whether at least one of an end tool and a connector is mounted based on a connection status of a second connection member;
• and
• transmitting and receiving information about at least one of the end tool and the connector based on a connection status of a first connection member,
• wherein the end tool includes one or more jaws formed to be rotatable,
• the connector is formed to connect between a handle and the end tool through a first connection member and a second connection member, wherein the first connection member includes one end to which a first contact of the end tool is connected and another end to which a third contact of the handle is connected, and the second connection member includes one end to which a second contact of the end tool is connected and another end to which a fourth contact and a fifth contact of the handle are connected, and
• the handle controls a motion of the end tool and detects a mounting of one or more components directly or indirectly connected thereto,
• wherein the first connection member is formed to extend in a direction from the handle toward the end tool,
• wherein the second connection member is formed to extend in the direction from the handle toward the end tool,
• wherein the one end and the another end of each of the first connection member and the second connection member are formed to be inclined with respect to a plane perpendicular to the direction from the handle toward the end tool.
