[0002] Staplers are generally divided into disposable or multiple-use staplers, imported or domestic staplers. They are devices used in medicine to replace traditional manual suturing. Due to the development of modern science and technology and the improvement of manufacturing technology, the staplers used in clinical practice are of reliable quality, making it possible to remove tumors that were previously inoperable. Staplers are devices used in medicine to replace manual suturing. Their main working principle is to use titanium nails to sever or staple tissues, similar to a stapler.

[0003] During the use of the laparoscopic stapler, when suturing is required at certain specific angles, the angle of the stapler magazine needs to be swung so that the angle of the stapler magazine and the wound are aligned. The swing mechanism of the laparoscopic stapler used in daily life is mostly driven by a driving device, which makes it very cumbersome to disassemble and install the device in case of internal structure failure during use, reducing the practicability of the device during use.
