Description

Technical Field

[0001] The utility model relates to the technical field of positioners, in particular to a four-point intraocular lens suspension positioner. Background Art

[0002] An intraocular lens, also known as an artificial lens, is a precision optical component that is surgically implanted into the eye to replace the removed natural cloudy lens. In cases where the lens capsule ruptures due to complications during phacoemulsification cataract extraction surgery, or due to ocular trauma and other eye diseases, the intraocular lens cannot be placed into the capsular bag. In such situations, an intraocular lens suspension surgery is required. The intraocular lens suspension surgery is a complex and delicate ophthalmic surgery mainly used to suspend and fix the intraocular lens in an appropriate position in the eye to restore the patient's vision. During the intraocular lens suspension surgery, in order to accurately find the suspension points of each loop of the lens and the sclera after the intraocular lens enters the eye, a positioner is needed for assistance.

[0003] For example, the patent with the publication number CN114504405A (an intraocular lens suspension surgery positioner): includes an operating handle, one end of the operating handle is connected with a hemispherical positioning member, and the inner side of the positioning member is provided with a positioning fitting surface adapted to the cornea; two positioning parts are oppositely arranged on the positioning fitting surface, and the positioning parts are provided with a plurality of marking teeth and positioning feet extending towards the inside of the positioning member. The positioner of the present invention is for intraocular lens suspension surgery, can accurately determine the puncture positions of two symmetric suspension points on the cornea, does not need to rely on the doctor's personal experience for positioning, can help the doctor quickly find the symmetric and accurate puncture positions of the two suspension points, improve the surgical accuracy and surgical effect, shorten the surgical time, make the intraocular lens in an ideal position, and avoid problems such as decentration, tilt, anterior or posterior position deviation of the optical zone of the intraocular lens after surgery, and improve the surgical effect and the patient's visual quality.

[0004] Although the above-mentioned prior art is convenient for positioning two suspension points during the implantation of the intraocular lens, the intraocular lens supported by two points may flip, greatly affecting the visual function. When positioning during the four-point intraocular lens suspension surgery, it cannot accurately position the four-point intraocular lens, affecting the accuracy of the placement of the intraocular lens during the four-point intraocular lens suspension surgery. For this, we propose a four-point intraocular lens suspension positioner. Content of the Utility Model
