Description

Disposable marker for ophthalmic surgery

Technical Field

The utility model relates to the technical field of ophthalmic surgery, in particular to a disposable marker for ophthalmic surgery.

Background

When ophthalmic surgery is currently performed, an intraocular lens is required to be implanted into the eye of a patient, and the surface of the cornea is marked by using a marker, so that the surgery difficulty is reduced, the surgery efficiency is improved, and the surgery accuracy and safety are ensured. For example, in the case of astigmatism correcting intraocular lens surgery, a surgeon uses a marker to perform pre-operative identification, to make an incision and to place an axial mark in the torico based on the marked horizontal position. It is still necessary to confirm that the axial orientation of the ToricIOL is consistent with the preoperative marker after the end of the procedure. Accurate axial marking is therefore critical in toricos procedures for effectively correcting corneal astigmatism. However, current markers suffer from the following disadvantages:

1. the existing marker is marked by a marker pen or a needle head when the marker pen is used for marking, inconvenient measurement and inaccurate measurement can occur when the marker pen is used for marking, and the condition that eyes of a patient are injured due to misoperation can occur when the needle head is used for marking;

2. when the existing marker is used, the instrument is often switched to mark after measurement is performed, so that errors occur between measurement and positioning when the instrument is switched, and the positioning accuracy is affected;

3. most of the existing markers are made of stainless steel or titanium alloy materials, and the existing markers need to be cleaned after being used and stored in a sterile mode, so that labor capacity is increased, and storage is troublesome.
