Multipurpose inner eye flute hook electric coagulator

Abstract

The invention discloses a multipurpose inner eye flute hook electric coagulator. The multipurpose inner eye flute hook electric coagulator comprises a flute needle body, a blow-attract device and an electric coagulation device. The inner eye flute hook electric coagulator can be placed into one eye when being used through a minimally invasive small invasion just for once, the rear end of the inner eye flute hook electric coagulator is connected with a vitreous cutter, and inner electric coagulation current can be generated and controlled after a circuit is started; a film hook at the point end of the inner eye flute hook electric coagulator can be subjected to the operations of hooking, pulling or handling; and by manually pressing a hollow rubber tube, liquid outside a pipette can be blown, the liquid outside the pipette can be attracted due to negative pressure caused by loosening the hollow tube, the bleed blood during an intraocular surgery can be cleaned, thus the operations of hooking, pulling and handling and electric coagulation bleeding can be simultaneously finished in an intraocular microscopy minimally invasive surgery, the surgery time can be shortened, the happening of surgical complications can be avoided, a rear end interface of the inner eye flute hook electric coagulator can be compatible with the vitreous cutter and a surgery microscope which are widely used in China at present, the practicability is strong, and the reliability is high.

Description

technical field [0001] The invention relates to a medical device, in particular to a multi-purpose inner eye flute hook electrocoagulator for ophthalmic vitrectomy, which integrates a flute needle, a membrane hook and an electrocoagulator. Background technique [0002] For the treatment of advanced hemorrhagic retinopathy, complex retinal detachment, severe ocular trauma and other fundus diseases, the retina must be reattached with the help of vitrectomy technology. During the operation, it is often necessary to remove the fibrovascular proliferation membrane, disconnect the fibrovascular scar, Partial retinal incision and other techniques often encounter bleeding during operation. It is necessary to inhale with a flute needle first, and then electrocoagulate to stop the bleeding. What makes it difficult for the operator is that the speed of alternately changing instruments is always slower than the speed of bleeding, and A variety of instruments come in and out repeatedly t...

Problems solved by technology

[0002] For the treatment of advanced hemorrhagic retinopathy, complex retinal detachment, severe ocular trauma and other fundus diseases, the retina must be reattached with the help of vitrectomy technology. During the operation, it is often necessary to remove the fibrovascular proliferation membrane, disconnect the fibrovascular scar, Partial retinal incision and other techniques often encounter bleeding during operation. It is necessary to inhale with a flute needle first, and then electrocoagulate to stop the bleeding. What makes it difficult for the operator is that the speed of alternately changing instruments is always slower than the speed of bleeding, and A variety of instruments come in and out repeatedly through a minimally invasive small incision, which not only prolongs the operation time but also may increase intraoperative and postoperative complications. How to improve the efficiency of the treatment of neovascular proliferative membranes in vitreous surgery, shorten the operation time, avoid or reduce Surgical complications have become an urgent clinical problem that we are facing
