Problems solved by technology

In terms of the operation method, in the past, the proliferative membrane tissue was pulled and peeled off with membrane stripping tweezers. Since the fibrovascular membrane is tightly adhered to the retina, and there are many new blood vessels formed on the surface of the retina, when peeling off the proliferative membrane, It often leads to rupture of retinal blood vessels and retinal rupture, and induces many surgical complications, which seriously restricts the curative effect of surgery

Embodiment Construction

[0017] Below in conjunction with accompanying drawing, the embodiment of the invention is described in further detail:

[0018] Ophthalmic blunt separation tweezers, comprising two tweezers 1 whose tails are fixed together and whose front is in the shape of a blade. The blade portion 2 of the front portion is arranged on the outer side, the outer side is thinner and the inner side is thicker, forming a slope from the inside to the outside; the front end of the tweezers 1 is pointed; the blade 2 is a blunt edge.

[0019] The cross-section of the front part of the tweezers 1 presents a trapezoidal shape gradually from narrow to wide from outside to inside.

[0020] The material of the tweezers 1 is titanium alloy.

[0021] The traditional ophthalmic stripping forceps mainly use forceps to clamp tissue, and the point of force is to make the forceps play the role of "clamping inward" (inward force), and it is required to achieve sufficient closing force to clamp the tissue and pe...

Abstract

The invention relates to a pair of ophthalmic inactive separated forceps which comprises two forceps sheets, wherein the tails of the two forceps sheets are fixed together and the front parts of the two forceps sheets are respectively in a blade shape. The front part of each forceps sheet bends inwards relative to the middle part of each forceps sheet; a blade part at the front part of each forceps sheet is arranged at the outer side, the outer side surface is thinner, and the inner side surface of is thicker, thereby forming a gradient from the inner side to the outer side; the front end of each forceps sheet is in a tip shape; and each blade part is an inactive edge. The invention has the advantages that the ophthalmic inactive separated forceps can avoid the occurrence of retinal hemorrhage and retinal detachment in the operation process, greatly reduce the operation time, improve the success ratio of the operation and achieve the purpose of good recovery of the visual function after the operation.

Description

technical field [0001] The invention relates to a tweezer used for peeling off pathological tissues during operation, especially a separating tweezer used in ophthalmic diabetic retinal proliferative membrane operation. Background technique [0002] With the improvement of human living standards and the development of population aging, the incidence of diabetes is on the rise, and various eye diseases complicated by it seriously restrict the quality of life of human beings. Among them, diabetic retinopathy is the most common. According to data, 30,000 to 40,000 people around the world become blind due to diabetic retinopathy every year. In my country, there are about 7 million diabetic patients, and at least 70,000 people may be affected by diabetic retinopathy. Vision seriously affects the quality of life of human beings, so this disease has gradually become an important blinding eye disease worldwide. The root of its internal pathogenesis is the formation of retinal neovas...
