Description

Technical Field

[0001] This utility model relates to the field of ophthalmic medical equipment technology, and in particular to an anterior chamber angle separator. Background Technology

[0002] Gonioscopy (or iridotomy) refers to the separation of abnormal adhesions at the anterior chamber angle (such as adhesions between the iris and cornea or trabecular meshwork) through medical intervention (e.g., laser, surgery, or instrument manipulation), reopening the outflow channels for aqueous humor and thus lowering intraocular pressure. Patients with narrow anterior chamber angles are prone to high intraocular pressure. The main current treatment method involves surgical cataract removal combined with intraoperative iridotomy to improve angle width, increase aqueous humor outflow, and ultimately lower intraocular pressure. Before iridotomy, a hyperbaric gonioscope is prepared. During the procedure, the gonioscope is placed in contact with the cornea, and the anterior chamber angle structure is examined from various directions to determine the specific points requiring iridotomy. Afterward, the gonioscope is removed, and a viscoelastic agent is injected into the angle to be separated. The support effect of the viscoelastic agent is used for blunt separation of the angle. Alternatively, forceps can be used to detach the adhered iris root, releasing it from adhesion to the trabecular meshwork. Both of these separation methods are performed without direct vision, making it difficult to determine whether sufficient iridotomy has been achieved. Utility Model Content

[0016] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] like Figure 1-3 As shown, this utility model embodiment provides an anterior chamber angle separator, including a gripping part 1 and a head 2 connected to the gripping part 1. The head 2 includes an action end 21 for anterior chamber angle separation and a connecting end 22 for connecting to the gripping part 1. The upper surface of the action end 21 is provided with an inclined mirror polished structure.

[0018] In this embodiment, the length of the working end 21 is about 13mm. The working end 21 includes a base plate 211 and an upper working plate 212. The end of the base plate 211 is an arc-shaped structure. The upper working plate 212 is a three-section structure. The middle section structure is a mirror-polished structure. The upper working plate 212 includes an arc-shaped plate at the front end and an inverted V-shaped structure composed of two sections. The included angle of the inverted V-shaped structure is an obtuse angle. The arc-shaped plate and the arc-shaped structure at the end of the base plate 211 have the same shape and are superimposed. The curvature of the arc-shaped plate and the arc-shaped structure at the end of the base plate 211 are the same as the curvature of the corneal limbus.

[0019] In this embodiment, a support member 213 is provided between the base plate 211 and the upper action plate 212. The support member 213 can be a rod-shaped structure or a plate-shaped structure. The support member 213 is located at the turning point of the V-shaped structure and is perpendicular to the base plate 211. The included angle of the inverted V-shaped structure is 145°. The bottom of the base plate 211 has a frosted design, which can increase the friction between it and the iris when performing iris corner separation.

[0020] In this embodiment, the connecting end 22 includes a positive V-shaped structure with an obtuse angle, and the length of the connecting end 22 is approximately 13.5 mm. The included angle of the positive V-shaped structure is 135°.

[0021] In this embodiment, the outer surface of the grip part 1 is provided with anti-slip threads 11. The grip part 1 is a cylindrical structure with an overall length of about 97mm and a cylinder diameter of about 3mm. It is silver-white and made of stainless steel, which is heat-resistant and can be used after repeated high-temperature sterilization. The anti-slip threads 11 include two segments of thread structure and are intermittently distributed on the outer surface of the grip part 1.

[0022] The specific usage process of the corner separator in this embodiment is as follows: The standard procedure for phacoemulsification cataract surgery involves inserting the goniosynostosis separator into the eye through the main incision after the I / A aspiration of the cortex. The arc-shaped contact portion of the separator (the arc-shaped structure at the ends of the arc-shaped plate and base plate 221) is extended to the anterior chamber angle, and the iris root is gently pressed down. At this point, the structure of the anterior chamber angle is visible on the mirror-polished portion of the separator (the upper surface of the working end 22). If angle adhesions are present, the downward pressure is increased to perform blunt dissection of the angle at the adhesion site. This dissection process is performed under direct vision for greater precision.
