Description
Technical Field
The utility model belongs to the technical field of medical instruments, and particularly relates to an atrium separator.
Background
The angle between the cornea and the iris of the human eye is called the angle of the chamber, which is known as the anterior chamber angle and consists of the anterior and posterior walls and the crypts between the walls. There are trabecular meshwork and other important structures in the angle, the trabecular meshwork is the channel for aqueous humor outflow, if the peripheral corneal irises contact each other and even adhere, the channel is blocked, i.e. the angle is closed, the aqueous humor outflow will be blocked, the intraocular pressure will be increased due to the accumulation of the aqueous humor, and finally glaucoma is formed.
The treatment of glaucoma is divided into three types, drug, laser and surgery, all for the purpose of lowering intraocular pressure. Trabeculectomy has been the poor choice for glaucoma, but it has resulted in complications such as anterior chamber shallowness, ocular hypotony, and cataract exacerbation due to the sudden drop in intraocular pressure as the anterior chamber is penetrated intraoperatively. In recent years, with the continuous and deep understanding of the structure of the angle, it is found that the adhered angle can recover the function of draining aqueous humor after separation, so as to reduce intraocular pressure, and the angle separation technique has become the mainstream technique for glaucoma treatment, so that the angle separation tool is very important for the angle separation effect.
Currently, there are two major instruments used for isolating the angle, one is the capsulorhexis temples that are routinely used in cataract extraction, and the other is the separator that separates the peripheral iris from the angle blunt. The peripheral irises and trabecular meshwork are separated by pinching the capsularhexis temples and drawing towards the center of the pupils, patients can feel obvious pain in the operation, and the pupillary sphincter muscle can be injured by pinching the root irises at the tip of the capsularhexis temples, so that the postoperative pupils are enlarged, and the patients have glare and vision is reduced. The trabecular meshwork is 360 distributions, all has the drainage effect all around, and open scope is big more, and intraocular pressure reduction effect is better, and can not act on the iris all around with the blunt separator of separating of room angle because the angle problem to open the trabecular meshwork all around.
