ABSTRACT:
The pivotal connection between the legs of a two-legged device, such as a surgical forceps, having a first leg including a mounting passage formed therein and a second leg which is inserted in the mounting passage is formed by expanding the mounting passage of said first leg by heating at least the portion of that leg having the passage therein to a predetermined temperature; inserting a pivot member in a pivot opening in the second leg; inserting said second leg through the mounting passage of the first leg until the pivot member is within the confines of the mounting passage and then compressing the portion of the first leg having the mounting passage therein towards the other leg to engage the pivot member against the internal sides of the passage.
