Device for improving drainage of the aqueous humor within the eye of a living being
First Claim
1. A device for microsurgically improving drainage of the aqueous humor via the trabecular tissue 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 coaxial relationship with the probe; and
at least one optical element disposed in 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.

Abstract
A device is disclosed for ophthalmologic microsurgery for improving the drainage of the aqueous humor in the eye of a living being, wherein the device has an endoscope connected to a monitor screen and includes a tube-shaped probe adapted for insertion into an eye, and one or more channels co-axially disposed therein and provided with optical elements for focusing and transmitting images from the viewing field in the eye, and wherein the probe houses a surgical tool which is movable in axial direction and about the longitudinal axis so that by means of the oscillating and/or vibrating tool a passageway can be opened in the tissue of the trabecular meshwork for connecting the anterior chamber with the Schlemm'"'"'s canal.

43. A device for ophthalmologic microsurgery on the tissue of the trabecular meshwork in the eye of a living being for improving drainage of the aqueous humor comprising:
-
an endoscope;
a tube-shaped probe operatively connected to the endoscope and adapted for insertion into an anterior chamber in the direction of a trabecular meshwork of the eye, said tube-shaped probe including an optical channel and at least one working channel co-axially disposed in the probe;
a surgical tool adapted for cutting and clamping engagement with the tissue of the trabecular meshwork co-axially disposed in said working channel relative to a distal end of the tube-shaped probe;
one or more optical elements disposed in said optical channel for focusing on the viewing field and for transmitting images for outside viewing; and
a drive mechanism which is manually and electrically adjustable for moving said surgical tool in the direction of at least one of a longitudinal axis and a rotational axis for opening a surgical passageway connecting the anterior chamber with Schlemm'"'"'s canal.

44. A method for improving the drainage of aqueous humor via the trabecular tissue into Schlemm'"'"'s canal of the eye of a living being, comprising:
-
inserting a probe with a surgical instrument into the anterior chamber of the eye in a direction of the trabecular meshwork to a surgical site;
transmitting images from the surgical site for outside viewing; and
opening a passageway in the tissue of the trabecular meshwork with the surgical instrument for connecting the anterior chamber with the Schlemm'"'"'s canal.
