Description

Technical Field

[0001] The present invention relates to the technical field of ophthalmic equipment, and more specifically, to a device for performing goniotomy assisted by femtosecond laser. Background Art

[0002] The angle between the cornea and the iris is called the angle chamber, which is composed of the front and back walls and the recess between the two walls. It is the pathway for the outflow of aqueous humor. If the angle chamber is blocked or dysfunctional, the outflow of aqueous humor will be blocked, and the intraocular pressure will increase due to the accumulation of aqueous humor, eventually leading to the occurrence of glaucoma. Therefore, for patients with angle chamber dysfunction, they can be treated by opening the angle chamber (also called internal trabecular meshwork incision).

[0003] However, existing goniotomy surgeries require a surgical incision and are performed on an operating table.

[0016] (3) The stopper assembly provided in the present invention can lock the position of the positioning sleeve so that the user can adjust the position of the positioning sleeve in the selection slot to select the cutting angle range during the operation. When the cutting angle range needs to be adjusted, the handle is rotated, and the cam at the bottom of the handle stops squeezing the block. At this time, a pair of spring plates provided at the top of the block will release the compression state and drive the block out of the selection slot. At this time, the positioning sleeve can be moved along the selection slot to select the cutting angle range. BRIEF DESCRIPTION OF THE DRAWINGS
