With the development of medical instruments, an absorbable patch fixing nail appears on the market, and the hernia repair patch is fixed by injecting the fixing nail into tissues, so that the human soft tissues can be penetrated and fixed from multiple angles and directions, the surgical efficiency is improved, the working strength of doctors is reduced, and the pain of patients is reduced. The hernia patch fixing nail has a U-shaped structure, the fork arm ends on two sides of the patch fixing nail are provided with a pointed end and a barb, and the two fork arms are inserted into tissues to fix the patch, so that the structure is simple and the operation is flexible. However, due to the structural characteristics, in the use process, an implantation tool with two clamping arms is needed, and the two clamping arms of the tool are used for clamping the two fork arms of the fixing nail so as to provide enough rigid support for the two fork arms, and due to the operational specificity, one fixing clamp is needed to be taken successively for use in operation, so that continuous firing and fixing of the device are not facilitated.
Therefore, it is necessary to design and develop a new patch staple so as to realize continuous firing and use of the instrument and make the firing action of the instrument simple and reliable.

By adopting the structure form of the tightening belt or the tightening ring, the bending arm 2-1 is more convenient to form, but the subsequent binding and fixing of the bending arm 2-1 are relatively troublesome. It will be appreciated that the above-mentioned "instrument" has at least a staple pushing mechanism for pushing staples out of the firing, and a cutting or stripping mechanism for severing or stripping the connection between the bending arms 2-1, the cutting or stripping mechanism being configured to sever or strip the connection between the bending arms 2-1 before the staple pushing mechanism pushes staples out, so that the bending arms 2-1 can be automatically bent open after the staples are fired. As for the specific structural design of the above-mentioned "apparatus", the conventional structural design can be adopted according to the working principle of the above-mentioned apparatus, for example, the push rod controlled by the handle can be adopted by the staple pushing mechanism, the push rod is slidably arranged in the push tube, the cutting mechanism or the stripping mechanism is arranged at the tube orifice position of the push tube, the cutting mechanism can be a blade corresponding to the connecting structure between the bending arms 2-1, the blade can cut off the connecting structure between the passing bending arms 2-1 when the staple is fired, and the stripping mechanism can be a stop block corresponding to the connecting structure between the bending arms 2-1, and the stop block blocks the connecting structure between the bending arms 2-1 to strip the staple when the staple is pushed out for firing.
