Reverse glaucoma filtering bleb scar probing device

Abstract

The invention discloses a reverse glaucoma filtering bleb scar probing device. The reverse glaucoma filtering bleb scar probing device comprises an arc-shaped needle stem capable of being bent into any radian, wherein the needle stem has the specification of 24G to 26G, a hatchet-shaped knife edge is arranged at a needle tip of the needle stem, a bevel surface of the needle tip is level with an edge face of one side of the knife edge, and a needle cock is arranged at the tail of the needle stem and is used for being connected with a viscoelastic-agent-containing syringe needle cylinder. Aftera filtering bleb of glaucoma trabeculectomy is in dysfunction, reverse scar separation can be carried out through a corneal limbus incision through an anterior chamber; the needle cock is connected with a needle cylinder, the needle cylinder serves as a handle during separation, and a separation direction can be changed by bending the needle stem in any radian, so as to carry out extensive separation through a tiny corneal limbus incision; the hatchet-shaped knife edge is in linear contact with scar tissue, a separation surface is relatively smooth, a viscoelastic agent can be injected while separation, causing of new injuries is avoided, and once trabeculectomy can be ensured; and through carrying out reverse separation by timely using the probing device, a filter function can be maintained perpetually, repeated operations are avoided, and sufferings of sufferers are reduced.

Description

technical field [0001] The invention relates to the technical field of glaucoma surgery, in particular to a reverse glaucoma filter bleb scar detector. Background technique [0002] Glaucoma trabeculectomy is the most classic glaucoma surgery method. Its disadvantage is that scar tissue is prone to hyperplasia under the scleral flap and conjunctival flap, resulting in loss of function of the filtering bleb. [0003] The commonly used solution is to separate the conjunctiva by acupuncture, that is, to pierce the conjunctiva from the conjunctival surface, and sharply separate the scar tissue under the conjunctiva and scleral flap. The disadvantage of this method is that it is easy to cause bleeding under the conjunctival flap and scleral flap, resulting in The new injury may also damage the conjunctiva and scleral flap, resulting in more severe scar hyperplasia and having to be re-operated with transposition. [0004] Therefore, how to solve the problem of easily causing new ...
