Abstract
The utility model relates to the field of anal fistula drainage tubes, and discloses a telescopic anal fistula drainage tube which comprises a tube body, an extension tube is connected to the inner wall of the front portion of the tube body in a sliding mode, a drainage hole is formed in the outer side of the tube body in a penetrating mode, and an extension mechanism is arranged on the inner wall of the tube body and comprises a limiting assembly and a supporting assembly. The limiting assembly comprises a fixing piece, the fixing piece is fixedly connected to the inner wall of the pipe body, the inner wall of the pipe body is fixedly connected with a limiting bead, a limiting groove is formed in the outer side of the extension pipe, and the limiting bead is clamped to the inner side of the limiting groove. According to the utility model, by pulling the extension tube, the extension tube extrudes the limiting bead through the limiting groove and drives the tube body to deform, so that the limitation on the extension tube is relieved, and meanwhile, the deformation of the tube body is limited through the fixing piece, so that the extension tube can be conveniently limited, and the length of the extension tube can be adjusted according to the actual condition of a patient; the applicability of the device is improved, and the treatment effect is ensured.
