PCT No. PCT/GB96/02863 Sec. 371 Date Oct. 20, 1998 Sec. 102(e) Date Oct. 20, 1998 PCT Filed Nov. 20, 1996 PCT Pub. No. WO97/18764 PCT Pub. Date May 29, 1997This invention relates to a medical scalpel (10) that comprises a grip (20) and a scalpel blade (30) located on a blade carrier (40). The grip (20) and the blade carrier (40) are hingedly connected to each other by means of a hinge formation extending transversely to the principal axis of the scalpel. The blade carrier (40) is rotatable between an operative position, in which the blade (30) is exposed for use, and an inoperative position, in which the blade (30) is retained in a recess (22) formed in the grip (20). The blade carrier (40) is preferably adapted for one time rotation to and retention in the inoperative position of the blade (30) by engagement formations formed in corresponding surfaces of the blade carrier (40) and the grip (20). The scalpel is integrally moulded in injection moulded plastics material in which the hinge formation is constituted by an integrally moulded line of weakness (50) formed between the blade carrier and the grip. |
