Abstract: An intraocular lens insertion device and a cartridge which enable the intraocular lens to be inserted into an eye more stably and easily than ever before. A supporting portion 102 of an intraocular lens 100 arranged on a lens-advancing side in a lens-advancing direction x is pressed against a protrusion 21 so as to be bent backward. Thus, releasing the intraocular lens 100 from a nozzle portion 13 is allowed to begin with the releasing of a curved portion of the supporting portion 102 that has become U-shaped and hard to move freely. As a result, there can be provided an intraocular lens insertion device and a cartridge which enable the intraocular lens 100 to be inserted into an eye more steadily and easily than ever before.

Abstract: Provided is an intraocular lens insertion device capable of omitting a repeated operation after the intraocular lens is inserted into the eye. The intraocular lens insertion device (1) comprises a lens setting part (11) for mounting an intraocular lens (5) having an optic (6) and one or two or more supporting portions (7a and 7b) disposed at the outer edge of the optic (6), a plunger (4) for pushing out the intraocular lens (5) mounted in the lens setting part (11), and a nozzle (13) for releasing the intraocular lens (5) pushed out by the plunger (4). This plunger (4) includes a lens contact portion (32) for abutting against the outer edge of the optic (6), and a pushing portion (33) for pushing out the supporting portion (7b) arranged in the backward direction of a lens advancing axis (A).

Abstract: There is provided a therapeutic instrument, for storing a sheet-type therapeutic substance to which a liquid is delivered, and delivering the stored therapeutic substance to an affected part, including: a nozzle member 23 having an opening 34 on a tip end of a tubular part 31 in which the therapeutic substance can be stored, for charging and discharging the therapeutic substance; and a syringe unit 22 that selectively causes a negative pressure and a positive pressure to act in the tubular part 31 through a hole of a valve member 27, wherein the space 33 of the tubular part 31 is the space for sucking the therapeutic substance into the tubular part 31 together with the liquid by causing the negative pressure in the tubular part 31 by the syringe unit 22 when the therapeutic substance is stored therein, and is the space for pushing out the therapeutic substance to outside of the tubular part 31 together with the liquid by causing the positive pressure to act in the tubular part 31 by the syringe unit 22 when t
