Surgical stapler with rotating elements system

The surgical resection is the primary treatment for the most nonmetastatic cases of colorectal cancer. This surgical procedure takes time and is often very difficult. The invention relates to a new type of mechanical stapler with the aim of promoting the result and decreasing complications in colorectal surgical resection and anastomosis.
The stapler object of the present invention is used in the first phase of the surgical procedure, during resection. Existing methods close the intestinal tract with a series of stitches and this is often causes complications. Conversely, this stapler applies only two stitches capable of closing the entire lumen, thus reducing the risk of dehiscence. The peculiar feature of the invention is that the compression of the intestine, necessary and preventive for the application of the sutures, is obtained by opposite rotation of two elements. This causes a "collection" of the intestine on a very small area, unlike the linear staplers of current use, which cause the crushing and the formation of a long edge, known to be one of the predisposing causes for the dehiscence of the anastomotic site.

• Application of only two stitches to close the whole lumen
• Formation of a small suture edge
• Reduction of the risk of dehiscence
