Using Scissors to make a hole in lumen

I am using Scissors to make a circle hole in one side of my lumen which has a hollow tube shape.The problem is when use scissors the hole is made ib both side of the lumen. Is it possible to limit this option to make a hole just in one side? and is it possible to set a diameter of hole for scissors?

If you draw your scissors shape on a slice view instead of on the 3D view you can limit its extent. See the Slice Cut options. Also, you can use the Circle shape option.
