Abstract
A method of manufacturing a shaft of a surgical instrument including forming a proximal segment of the shaft to include one or more features for operably engaging the shaft to a first component of the surgical instrument, forming a distal segment of the shaft to include one or more features for operably engaging the shaft to a second component of the surgical instrument and forming an intermediate segment of the shaft. The proximal segment is welded to a proximal end of the intermediate segment; and the distal segment is welded to a distal end of the intermediate segment. The proximal and distal segments are welded to the intermediate segment such that the one or more features thereof are aligned in a pre-determined orientation relative to one another.
