The present invention relates to a self-rotating catheter joint, which comprises a joint body, one end of which is formed with an external thread, and the other end of which is formed with an external joint； a hub, which is a hollow columnar body and one end is rotatably sleeved on the joint body The outer joint portion has an internal thread and a pipe connection portion at the other end. The pipe connection portion extends toward the outer space and communicates with the joint body. An upper cover is a cover body and is rotatably sleeved to be located on the joint body. The outer joint part is covered with a hub； a seal is an elastic ring body with one side abutting the outer joint part and the other side abutting the flange； a conduit with one end passing through and fixed to the tube 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 rotation of the hub changes the direction of the catheter, the pipe body externally connected to the joint body does not accompany the rotation.本新型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，使得本新型應用於手術使用時，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。
