Abstract

The invention discloses an optical fiber catheter intervening Schlemm's canal and a preparation process of a button-head. The catheter comprises a Luer taper, a perfusion pipeline, an external opticalfiber, a tee joint, a use section catheter and an internal optical fiber; one end of the perfusion pipeline is connected to the Luer taper in series, the other end of the perfusion pipeline extends to the tee joint, one end of the external optical fiber is connected to an optical fiber joint in series, and the other end of the external optical fiber extends to the tee joint; the internal opticalfiber is arranged on the use end catheter, the use end catheter comprises a near end and a far end, the near end is a transition catheter, and the far end is an intervening catheter; the diameters ofinternal channels of the transition catheter and the intervening catheter are larger than the outer diameter of the internal optical fiber, and the button-head is arranged at the head end of the intervening catheter; and the diameter of the internal channel of the button-head is smaller than that of the internal channel of the intervening catheter. The optical fiber catheter intervening Schlemm'scanal has the advantages of small interventional resistance, minimal damage and high safety.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a preparation process for an optical fiber catheter inserted into a slime's canal and a circular end. Background technique [0002] Glaucoma is a common eye disease, especially easy to be born in adolescents, and it is an unpreventable disease with a high rate of blindness worldwide. Lowering intraocular pressure is an effective method for the treatment of glaucoma at this stage. Lowering intraocular pressure is divided into drug therapy and surgical treatment. Among them, surgical treatment is only carried out when drug treatment is difficult to achieve the effect. Its principle is to dredge the blocked tissue fluid in the slime's canal to reduce intraocular pressure. [0003] The traditional surgical method is trabeculectomy, the principle of which is to drain the aqueous humor from the inside of the eye directly to the outside of the eyeball through the stoma opening on the wal...
