<p>A hard instrument 10 comprises first and second limbs 11 and 12 which are readily separable by moving the limbs to an open configuration (fig 3). The limbs are pivotally connected by pivot peg 13 on limb 11 which passes through a hole 14 (Fig 5) in limb 12. The two limbs 11 and 12 are able to move pivotally relative to each other to close jaws 11a and 12a of the respective limbs. The peg 13 purely serves as a pivotal bearing for limb 12 and in no way retains limb 12 in contact with limb 11, this being achieved by integrally formed retaining lugs 15 and 16 on limb 11 which in use extend over a flat portion 17 of limb 12. The lugs 15 and 16 therefore maintain the limb 12 in pivotal connection with the limb 11. The hand instrument may be forceps. <IMAGE></p> |
