Abstract:
A device for microsurgically improving drainage of the aqueous humor via the trabecular meshwork into Schlemm's canal of the eye of a living being comprising:an endoscope; a tubular probe, having a proximal end operatively connected to the endoscope and adapted for insertion into the anterior chamber in the direction of the trabecular meshwork of the eye, wherein the probe has an optical channel and a working channel in axial relationship with the probe; and an optical guide disposed in axial relationship with the optical channel for focusing and transmitting images from a viewing field; a surgical tool, disposed in the working channel and movable at least in axial direction with respect to a distal end of the probe, for providing a passageway in the trabecular tissue to thereby connect the anterior chamber with the Schlemm's canal of the eye; wherein the surgical tool is operated by an electric motor coupled to a proximal end of the endoscope, said electric motor is disposed in a housing and is in operative connection by means of at least two catch members with an axially slidable sliding member disposed at the outer circumference of the housing for the manual adjusting movement of the surgical tool in axial direction of the probe; wherein the surgical tool is disposed on the electric motor with at a coupling member.
