Preferably, the outer surface of the tube taking ring is smooth, and the inner surface of the tube taking ring is provided with anti-slip teeth.

Preferably, the open end face of the extractor ring is coplanar with the extractor rod surface.

Preferably, the visual system comprises a probe rod, a handle is connected to a non-insertion end of the probe rod, a camera and a light source are arranged at an insertion end of the probe rod, and the camera is connected with the display device.

Preferably, a transparent protective film is arranged on the end face of the insertion end of the probe rod.

Preferably, the flushing channel outer opening can be closed by using a closing cap.

The scheme of the invention has the beneficial effects that the visible female double-J tube extractor can take tubes under a visible condition, shorten the tube taking time, improve the tube taking success rate and reduce the harm to patients in the tube taking process.

Detailed Description

The following further describes embodiments of the present invention with reference to the drawings.

As shown in fig. 1 to 5, the visible female double J-tube extractor according to the present invention comprises an extractor rod 1, a handle 2 provided at the rear end of the extractor rod 1, an open ring-shaped tube extracting ring 3 formed by spirally bending the extractor rod 1 with a diameter gradually decreasing at the front end thereof, and a soft sleeve 4 sliding back and forth along the extractor rod 1 fitted over the extractor rod 1.

The outer surface of the tube taking ring 3 is smooth, and the inner surface of the tube taking ring 3 is provided with anti-skid teeth 31. The opening end face of the tube taking ring 3 and the surface of the extractor rod 1 are on the same plane, so that the double J tubes 11 can conveniently slide into the opening of the tube taking ring 3, and due to the arrangement of the anti-sliding teeth 31, when the double J tubes 11 slide into the opening of the tube taking ring 3, the double J tubes are not easy to break away from the opening.

In order to realize the visualization of taking a tube, visual passageway 5 is arranged in the inner cavity of extractor rod 1, the outer opening of visual passageway 5 is arranged at the non-insertion part of extractor rod 1, the inner opening of visual passageway 5 is arranged at the insertion part of extractor rod 1, and the position of extractor rod 1 corresponding to the inner opening of visual passageway 5 is a transparent window 9, a visual system is inserted in visual passageway 5, so that the process of taking a tube can be photographed in real time.
