Abstract

The invention belongs to the technical field of medical instruments and relates to a split type aqueous humor drainage device. The split type aqueous humor drainage device comprises a puncture needle, a drainage tube and a throttling structure; a needle head of the puncture needle penetrates through a tube cavity of the drainage tube, and the tip end of the puncture needle extends out of the drainage tube to be suitable for puncture; and the throttling structure and the drainage tube are arranged in a split mode. When an operation is carried out, a medical worker sleeves the drainage tube on the needle head of the puncture needle, then punctures at a preset position, then punctures the drainage tube into the preset position from one end of the drainage tube along the needle head, then pulls out the needle head, so that aqueous humor flows out from the preset position through the drainage tube, then immediately connects the throttling structure with the drainage tube, throttles the aqueous humor flowing out of the drainage tube through the throttling structure, and controlsthe flow speed of the aqueous humor. Throttling is carried out only through the throttling structure, the medical worker does not need to control the flow speed of aqueous humor, the number of human factors is small, the flow speed of the aqueous humor is relatively stable, operation of the medical worker is simplified, and the aqueous humor drainage operation is more efficient.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a split aqueous humor drainage device. Background technique [0002] The principle of glaucoma treatment is to reduce the intraocular pressure of the patient. The main treatment methods include eye drops, oral antihypertensive drugs or surgery. [0003] Surgical therapy for glaucoma employs a variety of techniques, all of which aim to reduce intraocular pressure by reducing resistance to the outflow of aqueous humor by creating an artificial channel for the outflow of aqueous humor. For example, patent document CN209996599U discloses a multifunctional glaucoma aqueous humor drainage device, which includes a syringe, one side of the syringe is provided with a drainage tube, and the drainage tube is connected to the syringe through a connector, and the drainage tube is relatively One end of the connector is provided with a drainage guide, the middle of the drainage tube is...
