Abstract

The invention provides a surgical device for curing glaucoma by femtosecond laser transmitted by an energy transmission optical fiber. The surgical device comprises a femtosecond laser (1), a femtosecond laser output tail fiber (2) and an energy transmission optical fiber (4). One end of the energy transmission optical fiber (4) is fused with the femtosecond laser output tail fiber (2) so as to transmit laser, and the other end of the energy transmission optical fiber (4) is connected with a convex lens (5) through a lens seat (6), or the end face of the other end of the energy transmission optical fiber (4) is of a spherical structure (7) so as to realize the spherical refraction effect to focus laser light. The surgical device can be operated more finely in the water environment, can perform filtration surgery by substituting a scalpel, and has the advantages that hurts to surrounding tissues from the surgery and postoperation fibrosis effect can be effectively reduced, postoperation scarring is alleviated, and effect time is long and the like.

Description

technical field

[0001] The invention belongs to the field of medical instruments, and relates to a laser surgery treatment device, in particular to a laser surgery device for treating glaucoma. Background technique

[0002] At present, glaucoma is a group of diseases characterized by optic nerve atrophy and visual field defect. The damage is irreversible. It is currently the second leading cause of blindness in the world and seriously threatens human visual health. The main mechanism is: the outflow of aqueous humor is blocked, resulting in the accumulation of aqueous humor in the eye, increasing intraocular pressure, thereby compressing and damaging the optic nerve, causing a series of clinical manifestations mainly including decreased vision and narrowing of the field of vision, and eventually blindness. The most common surgical method for treating glaucoma is filtering surgery. That is to establish a new way of drainage of aqueous humor outside the eye, and to create a f...
