ABSTRACT:
A latching device for enabling pieces of tissue or foreign bodies to be held securely by medical forceps during a medical operation comprises two elongate spring members whose opposed ends are secured in closed, telescoping tubes which are hinged to the handles of a forceps. The forceps handles are elastically yielding to some degree and by closing them together the spring members are moved towards one another and are caused to hook together by means of butting faces. Hence the tissue or the like which the forceps has taken hold of is automatically held secure once the manual pressure on the handle has been relaxed. If the handles are pressed closer together, the hooked interengagement is released and the spring-loading in the forceps handles opens them and allows the forceps jaws to release the tissue or the like which is being held.
