Detailed Description
In order to make the technical problem, technical scheme and beneficial effect that the utility model will solve more clearly understand, combine embodiment and attached drawing, it is right to go on further detailed description the utility model discloses. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. The technical solution of the present invention is described in detail below with reference to the embodiments and the drawings, but the scope of protection is not limited thereto.
As shown in figure 1, the forceps for preventing the long foreign bodies in the alimentary canal from slipping out comprises a handle 1, a slide block 2, an outer tube 3, a pull rope 4 and a net sleeve 5, wherein the handle 1 is provided with a finger sleeve hole 9. The handle 1 is provided with a sliding groove, the slider 2 is slidably arranged in the sliding groove, the slider 2 can slide back and forth along the sliding groove by pushing or pulling the handle 1, the pull cable 4 is sleeved inside the outer tube 3, the slider 2 is connected with the rear end of the pull cable 4, the front end of the pull cable 4 is bent into a ring 6, the end part of the front end of the pull cable 4 is bent into a ferrule 7 (shown in figure 2), the ferrule 7 is sleeved on the pull cable 4, so that the ring 6 can be contracted by controlling the length of the pull cable 4, and the opening of the net sleeve 5 is fixedly connected to the ring 6; the middle part of the net sleeve 5 is an elastic inward-contracting structure 8, so that the net sleeve 5 is integrally calabash-shaped; the depth of the net sleeve 5 is 2 times of the diameter of the circular ring 6, the material of the net sleeve 5 is the same as that of the medical rubber glove, and the thickness of the net sleeve 5 is 0.05-0.1 mm.
