Problems solved by technology

However, this operation faces a problem: after the cancerous tissue is resected with a surgical closed cutter, two sharp corners will be left on the stump, commonly known as "cat ears" in the industry, and these two "cat ears" are difficult to be completely removed. resection
When the anastomosis is performed with a round tube anastomosis instrument, the staples on the "cat's ears" will be cut off, which will affect the shape of the staples at the staple cutting site, cause bleeding, and postoperative excrement will enter the tip Horns, easy to infect wounds, sharp corners in the body will also cause certain damage to other tissues
