Abstract
A method for forming a suture-receiving hole in an eyeless suture needle. An oxidation resistant needle material and a heat resistant pressing tool are provided. The base end of the needle is heated to a temperature near its melting point and the heat resistant perforating tool is pressed into the base of the needle to form the desired suture-receiving hole. As an alternative, a preliminary hole can be formed in the base end of the needle material before the perforating tool is pressed into the hole as the final finishing step. Other variations include rotating or vibrating the perforating tool as it is pressed into the base end of the needle.
