The application discloses a glaucoma drainage device and belongs to the technical field of medical devices. The glaucoma drainage device comprises a drainage sheet, the inside of which is a cavity structure, the drainage sheet is divided into a left cavity and a right cavity through a first partition plate, the upper surface of the left cavity is provided with a drainage hole, and the first partition plate is provided with a drainage opening; a drainage assembly is in communication with the inside of the drainage sheet through a connecting hole provided on the drainage sheet; and a fixing mechanism is arranged on the drainage sheet and used for fixing the drainage sheet and the drainage assembly. The glaucoma drainage device can fix the drainage assembly and the drainage sheet of the device through a mechanical fixing structure, avoids the problems of the suture fixation of the drainage device in the prior art, simplifies the operation process, shortens the operation time, reduces the complications caused by the suture foreign matter, and improves the fixing reliability and safety.

The present application relates to the technical field of surgical knives, and discloses a trabeculectomy knife with adjustable knife distance, which comprises a knife handle, a knife rod connected with the knife handle, and a knife head connected at the end of the knife rod, wherein the knife head is boat-shaped, has a knife tip and two side edges, the rear sections of the two side edges are connected and the front ends thereof meet at the knife tip, the knife head has a concave cavity, the concave cavity is provided with a chevron-shaped gap for separating the knife tip, a pair of parallel first sliding grooves are arranged in the side wall of the concave cavity, an arc-shaped plate is slidably arranged in the first sliding grooves, and the two parallel edges of the arc-shaped plate are respectively clamped in the two first sliding grooves. The trabeculectomy knife can realize mode switching of the knife head and width adjustment of the side edges by single-handed holding, the big thumb can accurately control power transmission by rotating the knob, the friction fit of the threaded transmission and the wedge structure ensures smooth movement without slipping, and the operation difficulty is reduced without the need for additional instrument assistance or double-handed operation.

The utility model discloses a device capable of forming an opening in the trabecular meshwork of the eye, comprising a handle, a cutting element, a sheath tube and a pushing element, the cutting element comprises an elongated rod and two cutting blades, the tail of the elongated rod is fixedly connected with the head of the handle, and the head of the elongated rod is connected with the two cutting blades; the two cutting blades are symmetrically arranged with a predetermined opening, and the head of each cutting blade has a cutting part capable of penetrating into the trabecular meshwork and cutting the trabecular meshwork; the sheath tube is sleeved on the elongated rod and can slide along the elongated rod; the pushing element is connected with the handle and can drive the sheath tube to move towards the direction of the two cutting blades, so that the two cutting blades are closed to each other under the extrusion of the sheath tube to cut the trabecular meshwork, the cut tissue is easy to be peeled off from the trabecular meshwork, the cut part of the trabecular meshwork can form a trabecular meshwork opening, and the aqueous humor in the anterior chamber is promoted to flow out of the trabecular meshwork opening to reduce the intraocular pressure; and the size of the trabecular meshwork opening can be controlled during the cutting process.
