Abstract
The present invention concerns a method for manufacturing a needle, of the type used in the medical field. This needle is formed by a pulsed laser weld for joining a first portion having a pointed end and a second end having the shape of a tube and for receiving, in a subsequent step, the end of a suture thread. During the welding step, the needle and the incident laser beam are driven in a relative rotational movement whose speed is adjusted such that during the duration of a laser beam pulse, at least one complete revolution is carried out.
