[0002] The stapler is the world's first stapler, generally divided into disposable or multiple-use. It is a medical device that replaces traditional manual suturing. Due to the development of modern science and technology and the improvement of manufacturing technology, the staplers used clinically have the advantages of reliable quality, easy use, and fast suturing. It also makes it possible to remove tumors that were previously inoperable. The main working principle is to use titanium nails to separate or staple tissues, similar to a stapler.

[0003] The existing disposable arc-shaped cutting stapler does not have a good limiting mechanism for the firing rod during use. During the process of suturing the patient's skin, the firing rod may be accidentally triggered, causing the positioning needle inside the stapler to move, which is unsafe. In addition, when not in use, one side of the device's stapler is directly exposed to the air and may be contaminated by external bacteria, resulting in poor use effect. For this reason, we propose a disposable arc-shaped cutting stapler. Summary of the invention

A mounting block 12 is fixed to the front of the rotating plate 3. A slot 13 is provided on the inner wall of the mounting block 12. A slider 14 is provided on the inner side of the mounting block 12. An elastic member is fixed to the outer surface of the slider 14. The elastic member and the mounting block 12 are engaged and connected through the slot 13, so as to facilitate the adjustment of the position of the slider 14, and then the position of the first limit block 15 is adjusted through the slider 14. A first limit block 15 is provided on the rear surface of the rotating plate 3. The first limit block 15 and the slider 14 are fixed by a connecting rod. An adjusting slot 16 is provided on one side surface of the handle 2. The first limit block 15 and the handle 2 are pin-connected through the adjusting slot 16, so as to facilitate limiting the rotation of the rotating plate 3. A protective mechanism is provided on the arc-shaped clamping plate 7.

[0021] In this embodiment, preferably, the protective mechanism includes a protective silicone block 9, a first limit block 15 and a clamping block 18. The protective silicone block 9 is arranged on the arc-shaped splint 7. The side surface of the protective silicone block 9 is provided with a groove 17, and the groove 17 corresponds to the nail seat 8. The clamping block 18 is fixed on the lower surface of the protective silicone block 9, and a fixed block is arranged on the front side of the arc-shaped splint 7.
