Detailed Description

In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following embodiments.

As shown in fig. 1 to 3, the utility model discloses a drainage device a for ophthalmology vitreous cavity hematocele, it includes disposable drainage tube 1, pipe 2, drainage gasbag 3, rigid bag 4, be connected with a valve pipe 5 on one of drainage gasbag 3 or rigid bag 4, the other end of valve pipe 5 connects the host computer, and drainage gasbag 3 and rigid bag 4 pass through connecting pipe 6 and communicate, drainage tube 1 is inserted and is established on pipe 2.

The outer diameter of the drainage tube 1 is 0.4-0.89 mm (27-20G), the inner diameter is 0.3-0.7 mm, the head of the drainage tube 1 is made of silica gel or metal, and the drainage tube can be in an L-shaped hollow pipeline structure or a funnel structure with a wide head and a narrow end. The drainage tube 1 is connected with the vitreous cavity through the pars plana of the ciliary body, the head part of the drainage tube is connected with the vitreous cavity, the drainage tube is fixed through the oblique walking of the scleral wall and the self-closing of the spherical wall, or is externally fixed on the eyeball wall through the conjunctiva suture, and the funnel structure of the drainage device 1 is arranged in the vitreous cavity to play a role in collecting the hematocele of the postoperative vitreous cavity.
