AI Technical Summary

Problems solved by technology

This instrument has great disadvantages for rectal resection or esophagectomy and other limited surgical sites: firstly, the purse string can only be pulled along the transverse section of organ tissue, which requires a suitable operating space, otherwise it is easy The oblique force causes the staples to separate from the tissue, resulting in the failure of the purse bag. For the part with limited position, it is impossible to have a suitable operating space, so the risk of surgery in this kind of part is extremely high; Excessive pulling force may cause the staples to fall into the human body. Due to the limited position and the small size of the staples, it is not easy to find the fallen staples, which may eventually cause the staples to remain in the human body, which may pose a life-threatening threat to the patient.
