The present invention relates to a jig device for a medical relay. The jig device for a medical relay comprises: a base unit including wheels； a support extending from the base unit, and including a display unit； an extension bar extending in one direction from the support； a retractable bar installed on the extension bar to be retracted, and including a camera； a length adjusting unit configured to control a degree that the retractable bar protrudes from the extension bar, and adjust a length from the support to the camera； an adjustor extending in the other direction from the support, and including a lever member to adjust an extension direction of the retractable bar； an angle adjusting unit configured to rotatably connect the display unit to the support and maintain the display unit in a rotated state； a balance retaining unit configured to hold a balance of the support by increasing or reducing the weight of the adjustor when the retractable bar protrudes from the extension bar and a load through which the support is inclined in one direction is generated； a rotation lifting unit configured to vary a location of the camera and the display unit while lifting or rotating the support from the base unit； a foot switch detachably installed on the base unit, and configured to transmit a driving signal to the rotation lifting unit when a surgeon steps on using a foot； and a movement prevention unit configured to prevent the base unit from being moved by an external force applied to the base unit after the base unit is moved and a surgical operation is in progress. According to the present invention, it is possible to continuously provide an accurate auxiliary image.COPYRIGHT KIPO 2020본 발명은, 바퀴가 설치되는 베이스부； 상기 베이스부로부터 연장되고, 디스플레이부가 설치되는 지지대； 상기 지지대로부터 일측 방향으로 연장되는 연장대； 상기 연장대에 출몰 가능하게 설치되고, 카메라가 설치되는 출몰대； 상기 출몰대가 상기 연장대로부터 돌출되는 정도를 제어하며 상기 지지대로부터 상기 카메라까지의 거리를 조절하는 길이조절부； 상기 지지대로부터 타측 방향으로 연장되고, 상기 출몰대의 연장방향을 조절할 수 있도록 레버부재가 설치되는 조절대； 상기 디스플레이부를 상기 지지대에 회전 가능하게 연결하고, 상기
