The invention relates to an autonomous rotating catheter joint, which comprises a joint body with an external thread formed at one end and an external joint formed at the other end； a hub is a hollow cylindrical body and one end is rotatably sleeved on the joint body The outer joint part of the other end has an internal thread and a pipe joint part, the pipe joint part extends toward the external space and communicates with the joint body； an upper cover, which is a cover body and is rotatably set on the joint body The outer joint part is covered with a hub； a seal is a ring body with elasticity and one side is against the outer joint part, and the other side is against the flange； a duct is fixed at one end through the pipe The joint part is rotatably combined with the hub by the joint body, so that when the present invention is applied to surgery, when the hub is rotated to change the direction of the catheter, the tube body externally connected to the joint body does not rotate with it.本發明係一種自主旋轉導管接頭，其包含一接頭本體，其一端形成有外螺紋，另一端形成有一外結合部；一輪轂，其為一中空柱狀體且一端可旋轉地套設於接頭本體的外結合部，另一端具有一內螺紋及一管接部，管接部朝向外部空間方向延伸且與接頭本體相連通；一上蓋，其為一蓋體且可旋轉地套設定位於接頭本體的外結合部上並蓋設輪轂；一密封件，其為一具有彈性的環體且一側面貼靠於外結合部，另一側面貼靠於凸緣；一導管，其一端穿設固定於管接部；藉由接頭本體可旋轉地與輪轂結合，使得本發明應用於手術使用時，當旋轉輪轂改變導管方向時，外部連接於接頭本體的管體並不會伴隨發生旋轉。
