Apparatus for locking surgical instrument by using magnetic force

An apparatus for locking a surgical instrument by using magnetic force, characterized by comprising:

• a rotating locking unit configured to be moved and rotated in order to:
• apply an attractive force and a repulsive force according to movements in a locking direction and a release direction, respectively;
• lock a surgical instrument by formation of a locking magnetic force caused by the attractive force;
• and unlock the surgical instrument by formation of a release magnetic force caused by the repulsive force;
• a rotating body unit having a space into which the rotating locking unit is moved in the locking direction and the release direction and configured to transmit a transmitted driving force to the surgical instrument;
• a stationary locking unit configured to interact with the rotating locking unit to form the locking magnetic force and the release magnetic force;
• and
• a stationary body unit configured to transmit the driving force to the rotating body unit and comprising the stationary locking unit therein,
• wherein the stationary body unit comprises:
• a surgical instrument holder having a hinge groove, in an end thereof, by which a coupling unit extending upward from an end of the stationary body unit to couple the surgical instrument with the rotating body unit is supported and mounted, so that the surgical instrument is inserted and installed in the hinge groove in a rear-to-front direction, and locking of the surgical instrument is released as the rotating locking unit is rotated by using the hinge groove as a rotation axis according to the release magnetic force;
• and
• a rotating body support extending upward from a position spaced a predetermined distance from the surgical instrument holder in the horizontal direction to support the rotating body unit.
