Abstract: A safety scalpel has an elongated central body (1) having at each of its opposite ends (2, 3) a retractable lancet system comprising: a protection member (4) having a slot (12) and being connected to the elongated central body (1) and concentric thereto; a prismatic guide concentric to the elongated central body (1) and located inside the protection member (4); and a lancet holding member 20) consisting of a distal part (21) in the form of a prismatic member in which the lancet (24) is frontally inserted, and a proximal part (22) formed by two parallel arms (25, 26) having an end integral with the prismatic member, an arm (25) of them being slidable in contact with the prismatic guide, and the arm (26) carrying on a button (27) protruding from the slot (12) and provided with retaining elements (28) intended to be received into stop recesses (10, 11) of the slot (12).

Abstract: An intraocular lens injector with push control device has, in a pen-like casing (1), a front part (2) including a loading chamber (3), a tapered delivery channel (4) and a distal tip (5), a rear part including an actuator (18) comprising a coil spring (8) acting on a push rod (9) connected anteriorly to an insertion rod (19) for inserting the intraocular lens (IOL) in a patients eye, the coil spring (8) being housed on a spring-holding sleeve (10) provided with a front abutment member (11) joined to the push rod (9), and an intermediate handle part (6) on which a device for controlling the advancement of the push rod (9) is provided. The coil spring (8) has a rear end (13) with a variable longitudinal position by means of a screw and nut screw device (14) that adjusts the loading of the coil spring (8).

Abstract: An intraocular lens injector with controlled insertion has in a pen-like casing (1) a rear part including an actuator (18) connected anteriorly to an insertion rod (19) for inserting the intraocular lens (IOL) in a patient's eye, and an intermediate handle portion (6) on which a device for controlling the advancement of the push rod (9) is provided. The push rod (9) has a prismatic shape, and is provided with a toothed rack (24), and the device for controlling the advancement of the push rod (9) engages and disengages with respect to the toothed rack (24) co-operating as an elastic return element abutting the pen-like casing (1) to control the advancement of the push rod (9).
