The present invention provides a cutting device of a cutting system using a robot. According to the present invention, vibration of a shaft does not occur, and strength for bending is enhanced. A diameter of a sleeve is minimized, so interference of and damage to bones, muscles, and surrounding soft tissue can be reduced during an operation and durability is improved. The cutting device of a cutting system using a robot according to the present invention is a cutting device of a joint cutting system including: a shaft coupled with a motor formed in a robot arm part; a cutter formed with a cutting head on an end part of the shaft; and a sleeve having the shaft inserted therein. The sleeve comprises: a shaft insertion unit having a shaft insertion hole in which the shaft is inserted; and a reinforcement wing unit integrally extended in on side of the shaft insertion unit, and providing strength for bending to the shaft insertion unit. Accordingly, a large load is applied to the shaft by upward, downward, left, and right movement of the cutting head during an operation. Even when a bending load is repeatedly applied to the shaft insertion unit of the sleeve, strength for bending is reinforced by the reinforcement wing unit. Therefore, even when the overall thickness of the sleeve is minimized, the sleeve is not easily bent or deformed. The thickness of the sleeve can be minimized, and interference of and damage to bones, muscles, and surrounding soft tissue can be reduced during an operation, so operation stability is improved and a patient recovering period can be reduced. |
