SPECIFIC DESCRIPTION OF THE EMBODIMENTS

[0040] Refer to the advancing and self-locking device and a circumcision device, as well as the assembling method and the application method.

[0041] The present invention is described in detail below on the basis of the drawings, which is a preferred embodiment of the present invention.

[0042] Referring to FIGS. 1-5, in the preferred embodiment, the sheathed handle 1 is provided with an identification point 1-1 and is sleeved with a sleeve 3.

[0043] During assembly, the sleeve 3 is rotated, such that a mark on the sleeve 3 leaves from the identification point 1-1, and the sheathed core 2 at this moment can be pushed to move. Then, the sheathed core 2 is pushed to advance axially in the sheathed handle 1, till the hook 4 moves across the first-stage convex plate 5. When an assembler continues to push the hook 4 to prop against the second-stage convex plate 6, but not moving across the same, the sheathed core 2 is loosened, such that the sheathed core 2 is positioned at the inner side, i.e., a first locking position, of the first-stage convex plate 5 under the action of a spring 15.

[0044] Handles 10 and connecting rods 12 are then mounted on the sheathed core 2 and the sheathed handle 3 to accomplish the assembly.

[0045] During use, the user presses the handles 10 to drive the sheathed core 2 to advance axially in the sheathed handle 3, till the hook 4 moves across the second-stage convex plate 6 to accomplish the circumcision of the prepuce.

[0046] At the end of a surgery, the user loosens the handles 10, the sheathed core 2 is positioned at the inner side of the second-stage convex plate 6 under the action of the spring 15, i.e., the hook 4 is positioned in the second locking position, and the handles 10 at the moment cannot reset to an initial state, thereby accomplishing the self-locking of the circumcision device. The user can accurately judge whether an apparatus has been used by observing the positions of the handles 10, which is simple, intuitive, high in accuracy and effectively avoids medical accidents.

[0047] Exemplary descriptions are given for the present invention with reference to the drawings in the above. Obviously, the present invention is not limited to the above implementation manners. Any improvement using the methods, concepts and technical solutions of the present invention or direct application of the present invention to other occasions without modifications shall fall into the protection scope of the present invention.
