Abstract

In a circular stapler one of the key unmet needs is the removal of the device from anastomosis sitewithout putting excessive tension on the staple line Current EES staplers use a twist and turntechnique to remove the device by button holing Another unmet need is to increase the lumen size inanastomosis without increasing the diameter of the device The single row of staples should improveperfusion to the edge of the cut and help healing while at the same time reducing force to fire

Single Row Circular Staple Line with Maximum Lumen Size

Description

A pattern of staples is disclosed that allow for an effective anastomosis with a single row of staples that are placed in an accordion shape. The accordion shape naturally allows the straightening of the staple line with minimal tension during removal. The benefit of this is also that the lumen can get larger over time which is desirable. The non-circular lumen maximizes the lumen size.

The same can be utilized in other stapling devices to:
1. Reduce force to fire with less staples
2. Increase wire diameter to improve hold strength
3. Potential to minimize jaw size
4. Improve perfusion

Summary

In a circular stapler one of the key unmet needs is the removal of the device from anastomosis site without putting excessive tension on the staple line. Current EES staplers use a twist and turn technique to remove the device by button-holing. Another unmet need is to increase the lumen size in anastomosis without increasing the diameter of the device. The single row of staples should improve perfusion to the edge of the cut and help healing, while at the same time reducing force to fire.

Fig.1 shows one embodiment with the staples in an accordion shape. The cutline conforms to the accordion shape and should increase the lumen size. During removal the accordion shape would straighten out facilitating removal of the device. As tissue remodels the accordion shape would straighten out further increasing the size...
