The present invention relates to a laparoscopic surgical device having a four degree of freedom. The configuration of the present invention the grip comprising a grip control is provided being connected with the grip to the grip body and the grip body at one side which are provided in the grip, the grip side for cutting or hold a surgical site in the abdominal cavity for controlling the operation of the grip according to the moving position It is connected to the grip portion at one side longitudinal section, before a grip portion, and then, left and right and up and down joint including a plurality of joint bars provided in parallel to the movable, respectively And around the grip, and the driving since, first driven the end of the grip portion relative to the joint part left, right, up and down the first drive unit of the number corresponding to the plurality of articulated rod for driving, the grip portion is to be cut to hold or surgical and it characterized in that it comprises a 2 drive consisting of a third drive for forward and reverse rotation in one direction by the driving unit and the grip portion. According to the present invention, it is possible to improve the accuracy and precision by applying a joint part for increasing the grip force of the laparoscopic surgical device, the grip portion, the joint part and the drive unit consists of a simple configuration to ensure the stability of the driving and reduces the risk of malfunctions. Therefore enabling a reduction in the size of the surgical device does not require a large space is attached to the stand with a passive joint there is an effect that can be driven independently.Surgical devices, robotic, laparoscopic, 4 degrees of freedom본 발명은 4 자유도를 가진 복강경 수술장치에 관한 것이다. 본 발명의 구성은 복강 내의 수술부위를 잡거나 절단하는 그립, 그립 일측에 구비되는 그립 몸체 및 그립 몸체 일측에 구비되고 그립과 연결되어 이동위치에 따라 그립의 동작을 제어하는 그립제어부를 포함하는 그립부 그립부 일측 종단면과 연결되고, 그립부를 전, 후, 좌, 우 및 상, 하로 각각 가동하기 위해 평행하게 구비된 복수 개의 관절막대를 포함하는 관절부 및 그립부를 전, 후로 구동시키고, 관절부를 기준으로 그립
