Abstract
A surgical needle 20 includes a needle body 26 which is secured onto a hub body 24. The hub body 24 is irreversibly removable from the needle body 26 in order for the needle body 26 to be used as a trocar. The hub body 24, being irreversibly disconnectable from the needle body 26, ensures that the hub body 24 cannot be reconnected to the needle body 26 so that the surgical needle 20 cannot be used again.
