Abstract
The invention provides a self-suction cornea suction ring. A half-arc-shaped self-suction ring structure is added to the outside of a cornea ring body and can be right completely attached to the corneoscleral limbus, a proper amount of negative pressure suction force is automatically generated under the action of springback generated after a self-suction ring body is pressed downwards, and meanwhile a patient will feel comfortable subjectively to some extent when the suction surface of soft rubber causes negative pressure suction. The self-suction cornea suction ring can be well attached to the corneoscleral limbus, so that riboflavin can well permeate into the cornea ring body when corneal cross-linking is performed, waste caused by the fact that liquid flows out of eyes is effectively prevented, and operation time is shortened. In addition, the self-suction cornea suction ring is reasonable in design appearance, light in structure and more practical.
Description
Technical field
The present invention relates to medical instruments field, be specifically related to a kind of self-priming cornea and attract ring.
Background technology
At present, existing cornea negative-pressure suction ring is hollow ring made of plastic, and be connected to tee T and syringe, utilize syringe to deflate and make corneal ring firmly be fixed on limbus of corneae mainly on conjunctiva, the liquid medicine needed in performing the operation can be allowed well to rest in ring, and play the effect of fixing eyeball.But because be connected to, syringe is light not has certain influence to operation to present cornea negative-pressure suction ring, and the sense of discomfort of patient is than stronger, especially easily causes chemosis, hyperemia and subconjunctival hemorrhage.
Summary of the invention
In order to solve the deficiencies in the prior art, of the present inventionly providing a kind of self-priming cornea and attract ring.
The technical solution that the present invention adopts is: a kind of self-priming cornea attracts ring, comprise the corneal ring of tubular, self-priming ring is also provided with bottom described corneal ring, described self-priming ring is connected with corneal ring, described self-priming ring comprises half arc self-priming ring body, and the edge of described self-priming ring body is provided with the press section of a circle higher than cornea radian.
Described self-priming cornea attracts ring, and the diameter of described corneal ring is 9mm, and described self-priming ring diameter is 17mm, described self-priming ring body camber 3mm.
Described self-priming cornea attracts ring, and described self-priming ring adopts plastic material to make.
Described self-priming cornea attracts ring, adds the feed end of medicine when described corneal ring top is provided with operation.
Described self-priming cornea attracts ring, be provided with bottom described self-priming ring medicine enter cornea discharge end.
Described self-priming cornea attracts ring, and it is characterized in that, described cross section, press section is circular arc.
The invention has the beneficial effects as follows: the invention provides a kind of self-priming cornea and attract ring, the self-priming ring structure of one and half arcs is added again outside corneal ring, just in time can be fitted in corneoscleral junction completely, automatically appropriate negative-pressure sucking is produced by the rebound effect after pressing down self-priming ring, can be more comfortable to the subjective sensation of patient time the suction surface of simultaneously soft rubber causes vacuum suction, the present invention can well echo and on corneoscleral junction, riboflavin during corneal cross-linking art well be permeated in corneal ring, the waste effectively preventing from liquid from flowing out causing outside eye and accelerate operating time.And the design's outward appearance is reasonable, portable construction is more practical.

1-corneal ring in figure, 2-self-priming ring, 11-feed end, 21-press section, 22-discharge end.
Detailed description of the invention
Existing composition graphs 1 couple of the present invention is further described, a kind of self-priming cornea attracts ring, comprise the corneal ring 1 of tubular, self-priming ring 2 is also provided with bottom described corneal ring 1, described self-priming ring 2 is connected with corneal ring 1, described self-priming ring 2 comprises half arc self-priming ring body, and the edge of described self-priming ring body is provided with the press section 21 of a circle higher than cornea radian.Described self-priming ring 2 adopts plastic material to make.By arranging press section 21 between self-priming ring body and cornea, so that discharge by pressing implication forms vacuum suction.Described cross section, press section 21 is circular arc.Self-priming ring 2 just in time can be fitted in corneoscleral junction completely, automatically produces appropriate negative-pressure sucking by the rebound effect after pressing down self-priming ring, can be more comfortable to the subjective sensation of patient time the suction surface of simultaneously soft rubber causes vacuum suction.The feed end 11 of medicine is added when described corneal ring 1 top is provided with operation.Be provided with bottom described self-priming ring 2 medicine enter cornea discharge end 22.Make riboflavin during corneal cross-linking art be added in corneal ring by feed end 11, permeated by discharge end 22, the waste effectively preventing from liquid from flowing out causing outside eye and accelerate operating time.
The diameter of described corneal ring 1 is 9mm, and described self-priming ring 2 diameter is 17mm, described self-priming ring body camber 3mm, and the design's outward appearance is reasonable, and portable construction is more practical.
