In still another embodiment of the present application, the locking block 7.1 of the locking mechanism 7 is in the shape of arc teeth, the rotating shaft 1.1 is provided with a tooth-shaped structure, the arc teeth on the locking block 7.1 and the tooth-shaped structure on the rotating shaft 1.1 are meshed with each other to achieve the purpose of locking, and the purpose of locking is achieved by arranging gear meshing so that the rotating shaft 1.1 can be locked with the locking mechanism 7 regardless of the rotation of the rotating shaft with the first clamp 4 and the second clamp 5 by pulling the limiting piece 7.5.
In yet another embodiment of the present application, since a plurality of clips 6 are provided and sequentially enter the clip positions 4.41, if the clip 6 does not enter the clip positions 4.41 smoothly, i.e. when a portion of the clip 6 is located in the clip positions 4.41 of the first section 4.4, for example, most of the portion is located in the clip positions 4.41 of the first section 4.4, and another portion is located in the clip chamber 4.1 of the second section 4.5, for example, the portion is located in the second section 4.5, then the clip 6 will be partially stapled in the closed tissue, an operation accident occurs, because the blood vessel is not completely closed, and the clip 6 cannot be separated from the first clamp 4, but because of an in vivo blind operation, it may not be found in time, in the above operation, when the clip 6 is separated from the first clamp 4, since the clip 6 does not enter the clip positions 4.41 of the first section 4.5, at this time, the first section 4.4 is blocked by the clip 6, the locking mechanism 7 cannot rotate, the locking mechanism 7 is in a locking state, the rotating shaft 1.1 cannot rotate relative to the first clamp 4 because the first section 4.4 cannot rotate, the hand feeling resistance of an operator is obviously increased, the locking block 7.1 and the gear of the rotating shaft 1.1 can be hard ground, the operator can hook the limiting piece 7.5 by fingers, obvious pause feeling is felt, the limiting piece 7.5 is pulled to enable the locking wire 7.2 to pull the gear on the locking block 7.1 to be separated from the gear on the rotating shaft 1.1, the pause feeling can be obviously felt to disappear, the nail clamp 6 cannot be completely separated from the nail clamp bin 4.1 of the second section 4.5 by the process, the tissue is closed, and thus surgical accidents can occur, the two functions are realized by controlling the locking mechanism 7 to switch back and forth in the locking state and the free state, secondly, whether the nail clamp 6 is jammed in the nail clamp bin 4.1 is detected, and the tissue is not closed successfully.
While certain exemplary embodiments of the present application have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that modifications may be made to the described embodiments in various different ways without departing from the spirit and scope of the application. Accordingly, the drawings and description are to be regarded as illustrative in nature and not as restrictive of the scope of the application, which is defined by the appended claims.
