A fixed semi-ring 7 is fixed on the right side of the upper surface of the grip tube 1, and an arm wearing rope 8 is fixed inside the fixed semi-ring 7.

[0025] See also Figure 3In order to facilitate the adjustment of the overall length of the surgical valve opener and improve the convenience of subsequent use, in this embodiment, the adjustment mechanism 5 includes a fixed cover 501 fixed to the right side of the grip tube 1 by bolts, and the interior of the fixed cover 501 is rotatably connected to a first threaded rod 502 through a bearing, and a handle 503 is fixed to the right side of the first threaded rod 502. A first threaded groove 504 is opened on the right side of the movable rod 4, and the outer side of the left side of the first threaded rod 502 is threadedly connected to the inside of the first threaded groove 504.

[0026] In this embodiment, the adjustment mechanism 5 also includes a limiting groove 505 opened on the top wall and the bottom wall of the inner cavity of the grip tube 1, and the limiting groove 505 is internally slidably connected with a slider 506, and the opposite sides of the upper and lower sliders 506 are fixedly connected to the upper surface and the lower surface of the moving rod 4. By rotating the handle 503, the first threaded rod 502 threadedly connected to the inside of the first threaded groove 504 is rotated, and then the moving rod 4 is moved left and right inside the grip tube 1 under the action of the mutual cooperation between the upper and lower limiting grooves 505 and the slider 506, so that the overall length of the flap opener can be adjusted. A rubber pad 507 is fixed to the left side wall of the inner cavity of the first threaded groove 504, and the slider 506 makes a left and right linear movement inside the limiting groove 505.
