The blocking parts 4 at two sides (the blocking part 4 at one side) are arranged, so that the blocking parts 4 can be subjected to notch closing earlier, the blocking parts 4 at two sides are crossed at different heights or on the inner surface and the outer surface after being staggered (the blocking part 4 at one side and the arc-shaped piece at the other side are crossed in a staggered manner), the foreskin at the inner side is blocked, and the foreskin at the position of the guide opening 2 is uniformly distributed at the inner side along with the further folding process; the two side blocking parts 4 (the single side blocking part 4) can be set with reasonable length for pre-surrounding, and can be detached together with the detachment of the upper limiting piece 11 after realizing the function.

As a modified embodiment, the upper limiting member 11 is a plurality of blocking blocks arranged on the upper portion of the lower limiting member 12, the plurality of blocking blocks are arranged in a circle after the opening 2 is closed, and the blocking blocks and the lower limiting member 12 are detachably connected through easily-broken connection points 13 or insertion openings.

As shown in fig. 5, in the third embodiment, the circumferential arrangement formed by the plurality of blocking blocks can form an effective structural blocking on the circumference, so as to avoid the escape of the inner limiting seat 0 and assist the position limitation of the foreskin, and a good observation gap is left between the blocking blocks, through which a clear view can be provided for the operator in the operation process, which is helpful for more effective and accurate direct-view adjustment of the inner and outer plates and the frenum of the foreskin. Each stop block is detachably connected with the lower limiting piece 12 through an independent connecting point 13, and the connecting points 13 can be realized in structures such as a point, a sheet and a virtual line, so that the stop blocks can be conveniently broken by force in actual use, or can be cut by using surgical tools such as scissors or vascular clamps. In another embodiment, the blocking piece and the lower limiting piece 12 are detachably connected through a socket, and in this way, the blocking piece can be recycled after being sterilized, so that the environment is protected, and the cost is reduced.

As a modified embodiment, the lower portion of the upper stopper 11 is provided with a surrounding cavity 111, the surrounding cavity 111 is detachably mounted on the outer side of the lower stopper 12 from the outer side, and the upper stopper 11 is disposed on the upper portion of the lower stopper 12.
