Realize that a kind of embodiment of the present utility model is: described annular groove is located on the inner surface of lower end sidewall of described sleeve pipe.
Realize that a kind of embodiment of the present utility model is: described through hole is located at position corresponding with the annular groove of sleeve pipe on the sidewall of puncture tube, and is the annular layout.
The beneficial effects of the utility model are:
1, this utility model is provided with pretreated annular groove on the medial wall, lower end of sleeve pipe, and be provided with supporting with it puncture tube and expanding bar, driven by expanding bar that tumbler outwards rotates and drive sleeve extends out, make the lower end of sleeve pipe form the bell mouth shape opening, thereby change oozing of blood drain direction, reduce the chance that the chamber lens head is polluted by bloodstain.
2, the outer surface of sleeve pipe of the present utility model is provided with screw type screw thread, can reduce the damage to tissue, is easy to again fix simultaneously, is difficult for sliding up and down.
3, sleeve pipe of the present utility model adopts and has elastic medical plastic, medical polyurethane, medical grade rubber or medical silica-gel manufacturing, quality is softer, has again enough elasticity, except reducing tissue injury, also have flexibility, greatly improved the flexibility ratio of chamber mirror.More can reduce the wearing and tearing to the chamber mirror.
4, this utility model can be regulated according to patient's thoracic wall or thickness of abdominal wall, and a kind of product can adapt to thoracic wall and the stomach wall of various thickness.Also can wipe out long sleeve pipe and not damage shears with operating scissors easily at any time in art.
5, the outer surface of sleeve pipe of the present utility model is provided with graduation mark, is used for the depth of measuring and clearly adjusting.
