Chamber angle observation mirror

Abstract

The invention discloses a chamber angle observation mirror. The chamber angle observation mirror comprises a mirror frame and a lens installed on the mirror frame, wherein the mirror frame comprises ahandle, a floating support and a stabilization piece, and the handle, the floating support and the stabilization piece form the suspension mirror frame, so that the lens stably floats and is installed above the eyeball; the handle is used for installing the installation end of the lens and is hinged to the floating support which can rotate within a certain range, and one end of the floating support is hinged to the lens which can rotate within the certain range; the stabilization piece is in direct contact with the eyeball and limits the relative position between the lens and the eyeball; theend, facing the eyeball, of the lens is a concave surface, and the end, away from the eyeball, is a convex surface with a non-spherical surface; the optical axis of the concave surface and the optical axis of the convex surface are not coaxial, that is, the lens is of an off-axis lens optical framework. The observation mirror is very convenient to use in glaucoma surgeries, and the smooth and quick surgeries are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of glaucoma surgery, in particular to an observation mirror for glaucoma surgery. Background technique [0002] Glaucoma is currently the number one cause of eye diseases. The examination and treatment of glaucoma disease requires careful examination and surgical operation of the angle tissue in the eyeball. The lens-mounted handle in the prior art has a simple structure. Because of the limited size of the observation mirror itself, it is difficult to design more rotation control mechanisms to obtain good flexibility to quickly obtain the working position of the observation mirror, and it cannot adapt to patients during surgery. Eye movement within a certain range. And the existing optical system for chamber angle inspection mainly adopts a fixed contact mirror. Because the lens adopts mirror imaging, the imaging is a left and right mirror image, which is opposite to the direction of the doctor's operation...

Problems solved by technology

[0003] The purpose of the present invention is to solve the above-mentioned technical problems. By adopting the design of the suspension mirror frame and the off-axis lens optical structure, it effectively solves the inconvenience caused by the poor adaptability of the lens position adjustment during the doctor's operation, and the operation direction is opposite to the lens imaging direction. technical issues
