AI Technical Summary

Technical Problem

Even after the stapler is used to close the incision, a certain percentage of cases still experience oral leakage and bleeding at the incision site.

Method used

An anastomosis device is provided, including a repair assembly and an anastomosis device. The repair assembly includes at least one patch for different surgical procedures. The anastomosis device includes a shaft assembly, an anvil, and a cartridge, the anvil and cartridge being capable of relative closure. The patch is mounted on the anvil or cartridge and operates at the anastomosis site to achieve occlusion and reinforcement. The patch includes a scaffold and a biofilm, a support plate and an operating element for adhesion to the inside of the incision, and a cutting blade for cutting excess tissue.

Benefits of technology

By adhering and sealing the patch, the risk of oral leakage and bleeding at the incision site is reduced, and the reliability and adaptability of the anastomosis equipment are improved.
