Description

Improved ophthalmic microscopic inner limiting membrane forceps

Technical Field

The utility model relates to the technical field of ophthalmic instruments, concretely relates to micro-interior limiting membrane tweezers of ophthalmology of improvement.

Background

The ophthalmic microscopic inner limiting membrane forceps are one of the fine surgical instruments commonly used in ophthalmic vitreoretinal surgery and are used for separating and stripping the inner limiting membrane of retina or retinal proliferation membrane tissues. When the instrument is used for intraocular operation, an operator needs to hold the instrument to gradually approach and tentatively clamp the micro-thin inner limiting membrane tissue. The difficulty of this procedure lies in: 1, the tissue of the inner limiting membrane is very fine and micro-blogs about a few microns, and damage to the deep tissue of the retina can be caused by slight excessive clamping. Damage to retinal tissue is irreparable. 2 the depth of the eye is difficult to grasp, resulting in the operator often pinching the inner limiting membrane tissue.

Currently there is no effective improvement to the limitations of this ophthalmic micromanipulation beyond repeated operator practice. The operation difficulty is high, the learning curve is long, and the operation complication is difficult to avoid in the exercise process of the operator. Therefore, we intend to improve the surgical procedure by improving the inner limiting membrane forceps. First, excessive grasping of retinal tissue and depth within the eye is difficult to grasp in relation to the opacity of the metallic material at the ends of the inner limiting membrane forceps, thus affecting the visualization of the retinal tissue. Secondly, retinal tissue damage is related to the friction easily caused when the metal material of the forceps is clamped. Finally, the depth of the eye is difficult to grasp and is associated with limited magnification of the ophthalmic microscopic system, and thus limited visualization of retinal tissue.
