5 results about "Ophthalmic surgical microscope" patented technology

The utility model relates to the technical field of goggles, in particular to a turnover ophthalmology laser operation goggle which comprises a long-strip-shaped supporting frame, first blocking parts are arranged at the two ends of the supporting frame, and a second blocking part is arranged in the middle of the supporting frame; the first blocking part and the second blocking part form a placing groove for placing an ophthalmic operation microscope eyepiece; the fixing part is arranged on the support frame and is used for fixing the support frame on the ocular lens of the ophthalmologic operation microscope; the protective lens is hinged to the supporting frame through the connecting part. The ophthalmic laser operation goggles can be accurately placed on an eyepiece of a microscope through the placing groove, and when laser protection is needed, the protective lens can be put down to block in front of the eyepiece of the microscope, so that the protective effect is achieved; when the laser protection is not needed, the surgical field can recover to the conventional light only by turning over the protective lens upwards, the operation is simple and convenient, and the operation continuity of a doctor is not influenced.

An optical system for forming uniform illumination is disclosed. The optical system includes a light source coupled to a plurality of first light carriers providing a plurality of light intensities, and a second light carrier coupled to the plurality of first light carriers. The second light carrier spatially homogenizes the plurality of light intensities to form a homogenized light intensity. The optical system further includes an illumination module coupled to the second light carrier and operable to receive the homogenized light intensity.

The utility model relates to a zero-degree coaxial LED red light reflection device of an ophthalmologic operation microscope. A red light reflection light axis is arranged on a preset axis of a microscopic primary mirror; a microscope objective lens is arranged below the microscope primary mirror along the red light reflecting light axis; a miniature coaxial LED red light reflecting device is arranged between the microscope primary mirror and the microscope objective lens along a red light reflecting light axis; therefore, the generated light is coaxially irradiated with the microscopic primary mirror and the red light reflection light axis, and coaxial red light reflection illumination light is realized. The lens can be embedded between the left optical axis and the right optical axis of the primary mirror; a built-in integrated microscope is used for control; the zero-degree coaxial LED illumination light with an independent light source is high in illumination brightness and uniform in light spot, observation of a microscope is not affected, the zero-degree coaxial incident angle LED illumination light which is bright enough is achieved, and strong red light reflection is obtained. The device and the microscope are integrally controlled, the integrity of the microscope is realized, and the function of the microscope is improved.

The disclosure provides an ophthalmic surgical microscope including an optical axis. The ophthalmic surgical microscope also includes at least one light source configured to provide illumination having a wavelength range between 575 nm and 625 nm. The ophthalmic surgical microscope further includes a control device for directing the illumination at an acute angle relative to the optical axis of the microscope.

The present invention relates to a single and / or dual laser delivery system attached to an existing ophthalmic operating microscope, comprising of a single and / or dual wavelength laser unit [1]; and a delivery system [5]. The laser unit [1] comprises of a green laser module 532 nm [3] and a yellow laser module 577 nm [4] along with an aiming beam [7] 635 nm. The delivery system comprises of a right-angle prism [5A]: X and Y Galvo assembly [5B] and a focusing lens assembly [5C]. The laser unit passes through a fiber optic cable [6] gets reflected using the right angle prism, gets deflected by the Galvo assembly, enters the focusing lens assembly and gets reflected by a folding mirror [5D] and focused on human eye capsule. The system converges and focuses the laser wavelengths in line with the aiming beam to create a circular pattern to accomplish a pre-measured Capsulorhexis.
