Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a suturing nail for an endoscopic cutting anastomat.
Background
With the development of medical science and technology, doctors suture human tissues or organs by using medical anastomats and alloy staples instead of the original manual suture mode of using needles and threads. The medical anastomat is used for suturing, is convenient to operate, is safe to inosculate, causes little wound and is accepted by general surgeons.
However, most of the staples used in the existing medical anastomat are made of titanium alloy, and because the corrosion resistance of the titanium alloy is relatively high, the titanium alloy staples can be left in human tissues or organs for a long time after suturing, possibly causing inflammation, so that people always have uncomfortable feeling. Therefore, the anastomosis nail is made of magnesium alloy or iron alloy which can absorb and degrade. Generally, the anastomosis nail is made of iron alloy or magnesium alloy, the iron alloy has good supporting performance, but has too slow degradation speed, takes too long time for degradation in vivo, can not be degraded for a long time after wound healing, and is easy to cause discomfort for patients; the magnesium alloy has high degradation speed and high biological fusion with human bodies, but the magnesium alloy has poor supporting performance, and because the degradation speed is too high, the wounds of patients are not completely healed for many times, and the magnesium alloy starts to degrade, so that the wounds of the patients are easily wounded again. At present, magnesium alloy anastomats are used in a large variety, and the degradation speed of magnesium alloy is improved by improving the components of the magnesium alloy. But this approach is costly. Meanwhile, in the closed suturing nail forming process of the anastomat, the closed suturing nail is used for being subjected to external force such as tissue traction, the suturing nail is easy to twist and dislocate, therefore, the sutured tissue cannot be closed well, the wound recovery speed is reduced, the wound is easy to be infected by microorganisms, and then complications such as anastomotic fistula are caused.
