[0003]
An experienced doctor can incise the anterior capsule based on the size of the patient's cornea and the size of the dilated pupil as a reference, however, the size of the cornea varies from patient to patient, and the size of the dilated pupil also varies, so the final size varies. Not the same, and the shape of the incised anterior capsule is completely dependent on the experience and technique of the doctor, so it is difficult to incise the anterior capsule in a perfect circular shape, and, when the size and shape of the incised anterior capsule are not perfect , after the intraocular lens is implanted, additional surgery is required to adjust the size of the lens capsule, which is a waste of time and manpower

The invention relates to the technical field of medical instruments, in particular to an anterior capsulotomy guiding device for cataract surgery, which comprises a circular ring, an inner cavity of the circular ring is hollow, a groove is reserved in the surface of the circular ring, a supporting seat is clamped in the center of the top end of the inner cavity of the circular ring, and an inner cavity of the supporting seat is hollow, a hollow column is welded to the center of the top end of the circular ring. One ends of elastic strips are inserted into the left side and the right side of an inner cavity of the hollow column, the other ends of the elastic strips extend into an inner cavity of the circular ring and are flush with the end face of the groove, outer barrels of bearings are welded to the top ends of the elastic strips, and inner barrels of the bearings are in interference fit with threaded rods capable of rotating around the axes of the threaded rods. The elastic strip moves out of the circular ring along the inner wall of the circular ring and enters the groove, medical staff can adjust the size of the groove according to the size of the cornea of a patient and the size of the expanded pupil, and the anterior sac can be cut open accurately and perfectly.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to an anterior capsulotomy guiding device for cataract surgery. Background technique [0002] Cataract surgery is an ophthalmic operation, the purpose of which is to remove the clouded lens and insert a transparent artificial lens to replace the role of the natural lens. The natural lens has a capsule, the lens capsule, according to the lens during surgical removal. The relationship between the nucleus and the capsular bag can be divided into intracapsular extirpation and extracapsular extirpation. After removing the cloudy lens, an intraocular lens is often placed. Intracapsular or extracapsular placement of intraocular lenses can not only restore vision, but also restore the anatomical relationship in the eye and prevent the anterior vitreous from prolapse. If the anterior vitreous prolapses from the vitreous cavity to the anterior chamber and cornea or iris tissue Adhesi...
