Glaucoma drainage tube capable of being quantitatively adjusted through non-invasive type method

Abstract

A glaucoma drainage tube capable of being quantitatively adjusted through non-invasive type method comprises a hollow broad rubber hose and a narrow drainage tube which have the function of draining aqueous humor, inner tubes with the same length are arranged in the hollow broad rubber hose, a plurality of diaphragms are arranged in the inner tubes in an inclined mode, diaphragm support tubes are arranged between the adjacent diaphragms, a plurality of micro-holes are formed in the tube wall of the hollow broad rubber hose to make the inner tubes communicated with the outside of the hollow broad rubber tube, the tail end of the narrow drainage tube is communicated with the inner tubes and the front end is inserted in an anterior chamber so as to make an inner cavity of the inner tube at the front end of the diaphragm close to the narrow drainage tube, communicated with the narrow drainage tube, and the aqueous humor drained from the anterior chamber passes through the inner tube and is drained to nearby orbital tissue through the micro-holes of the hollow broad rubber hose; the diaphragms near the narrow drainage tube can be gotten through by lasers after an operation to gradually increase the diversion space between the narrow drainage tube and the diaphragms which are not gotten through and are close to the narrow drainage tube so as to gradually increase the drainage amount of the aqueous humor to reduce the intraocular pressure of orbital tissue, and therefore the non-invasive adjustment of the drainage amount of the glaucoma aqueous humor by the lasers in vitro is realized.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a glaucoma drainage tube that can be quantitatively adjusted by a non-invasive method. Background technique [0002] At present, ophthalmologists often use glaucoma drainage tubes to control the intraocular pressure of glaucoma patients, especially in the treatment of complex glaucoma. Gradually lose function after wrapping. The pressure control with the simple pressure control valve inside is extremely inaccurate and prone to failure. Neither the current drainage tube nor the drainage valve can be quantitatively adjusted in the later stage according to the needs after the operation, and they can only be replaced after failure. In addition, the target intraocular pressure of different stages of glaucoma is different, and the existing simple pressure control valve cannot set the target intraocular pressure before operation or adjust it after operation, which makes some patients co...

Problems solved by technology

However, when adjusting the intraocular pressure in the original application technology, it is necessary to incise the ocular surface tissue such as the conjunctiva, and push in or pull out part of the piston, which is likely to cause complications such as bleeding, infection, and scar formation, and generate relatively high surgery and related costs.
