A docking interface device

Abstract

The invention relates to a butt joint interface device for establishing a stable docking of a laser beam with an eye during a laser procedure, which includes an attachment device, a suction ring, a pressure distribution ring, and a vacuum device interface. The attachment device is connected to a laser light path outlet of the ophthalmologic operation equipment. The vacuum device interface is connected with an external vacuumizing device; the suction ring is in direct contact with the eyes, and negative pressure generated by the external vacuumizin device is distributed to the surfaces of theeyeballs through the pressure distribution ring, so that the vacuum pressure is prevented from directly acting on the eyeballs, corneal deformation can be reduced, pressure applied to the eyeballs bythe butt joint interface device is reduced, corneal deformation and corneal wrinkles are reduced, and operation safety is improved. According to the butt joint interface device, stable butt joint canbe established between a treatment laser beam and the eye during an ophthalmologic laser operation, a flattening lens is not in direct contact with the cornea of the eye in the butt joint process, optical path connection between the focusing lens and the front surface of the eye is completed through a liquid medium, and therefore rising of intraocular pressure caused in the butt joint process is reduced.

Description

technical field [0001] The invention relates to the field of ophthalmic laser surgery, in particular to a docking interface device, which can be used to keep the relative position of a therapeutic laser beam and an eye stable during ophthalmic laser surgery. Background technique [0002] In recent years, with the rapid development of laser technology, the use of laser for surgical treatment has become more and more common, especially in some operations that require delicate operations, such as the field of ophthalmology. Compared with traditional surgical methods, laser surgery greatly improves the accuracy of the surgical location and reduces the requirements for doctors' surgical skills. For example, in laser cataract surgery, capsulorhexis is required. When the lens capsule is torn with a scalpel, it often results in uneven capsulorhexis or even rupture of the capsule. Laser can personalize and precisely customize the tissue of specific parts. Cutting, ablation, etc., an...

Problems solved by technology

This distortion results in increased beam scatter and astigmatism, which may necessitate the use of higher energy laser beams

Distortion can also cause loss of laser beam orientation accuracy
