The medical patch is a human tissue repair material which is widely used in general surgery department and is mainly used for repairing various hernias, such as inguinal hernias, incisional hernias and the like. Due to the particularity of the hernia region, the patch needs to have strong tensile strength without losing softness, and also needs to have a proper shape according to the position of the repaired tissue so as to be stably fixed on the human tissue.
The fixation of the patch in human tissue is the key of hernia repair surgery, and the fixation effect directly affects the success or failure of the surgery and has a key influence on whether the surgery recurs or not. The patch is not firm and is easy to loosen or fall off, the existing hernia repair patch is usually fixed in a clinical suture mode, namely, the patch is fixed on tissue at a plurality of positions of the patch through suture lines, but the suture operation mode has low efficiency, the operation time is prolonged, the operation level requirement on doctors is high, the suture effect is not easy to guarantee, and meanwhile, the recovery of patients is slow. Along with the development of medical equipment, an absorbable patch fixing nail appears on the market, and the fixing nail is injected into tissues to fix the hernia repair patch, so that the human soft tissues can be penetrated and fixed from a plurality of angles and directions, a better fixing effect is achieved, the operation efficiency is improved, the working strength of doctors is reduced, and the pain of patients is also reduced. For example, the "applicator system for surgical fasteners" disclosed in chinese patent No. ZL201480015432.8 and the "hernia patch fixing nail and method for manufacturing the same" disclosed in chinese patent application No. 201810214855.2 have U-shaped structures, the tips and barbs are provided at the ends of the prongs at both sides of the nail, and the two prongs are inserted into tissue to fix the patch, so that the structure is simple and the operation is flexible. However, due to the structural characteristics, in the using process, an implantation tool with two clamping arms is required, and the two clamping arms of the implantation 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; due to the special operation, one fixing clamp needs to be taken one by one for use during operation, which is not beneficial to continuous percussion and fixation by using an instrument.
Therefore, a need exists for a new patch staple design that facilitates continuous firing use of the instrument and that provides a simple and reliable firing motion of the instrument.
