Description

Capsulorhexis forceps for cataract surgery

technical field

The utility model relates to a medical device, in particular to a device for ophthalmic surgery, specifically a capsulorhexis forceps for cataract phacoemulsification operation.

Background technique

As we all know, cataract phacoemulsification combined with intraocular lens implantation is a routine surgical method for the treatment of cataract. During the operation, a continuous annular capsulorhexis with a diameter of about 5.5 to 6 mm should be performed on the anterior capsule of the lens with capsulorhexis forceps, so as to form a capsular bag for implanting the artificial lens after phacoemulsification. A centrally sized circular capsulorhexis is very important for the long-term stability of the implanted IOL position. For experienced surgeons, the size of the capsulorhexis can be controlled by experience, while for beginners, the dilated pupil during the operation is usually used as a reference to complete the capsulorhexis. In the actual operation, due to the large difference in the diameter of the pupils of the patients, the size of the annular capsulorhexis is too large or too small, which affects the effect of the operation.

Contents of the invention

The purpose of this utility model is to design a kind of cataract with scale marks in order to solve the problem that there is no reference index when using capsulorhexis tweezers to perform capsulorhexis operation in cataract surgery. Manual capsulorhexis forceps.

The technical scheme of the utility model is:

A capsulorhexis forceps for cataract surgery, comprising left and right tweezers 1, 2, the upper ends of the left and right tweezers 1, 2 are connected, and their lower ends are bent in the same direction and are elastically opened. 1. The curved sections 3, 4 at the lower ends of the right tweezers 1, 2 are separately or simultaneously provided with a groove 5, 6 which can indicate the size of the capsulorhexis.

The distance between the grooves 5 and 6 and the claw tips 7 and 8 of the left and right tweezers 1 and 2 is 5.5 to 6 millimeters.

The beneficial effects of the utility model:

Utilizing the capsulorhexis forceps of the utility model to extend into the anterior chamber of the patient's glasses to prepare the capsulorhexis, the scale on the tip of the forceps can be observed and compared with the size of the pupil, which is conducive to estimating the size of the capsulorhexis and reducing the blindness of the operation. It is conducive to the rapid improvement of beginners' operation level and medical level.

In addition, the utility model has the advantages of simple structure and convenient manufacture or improvement.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

As shown in Figure 1.

A capsulorhexis forceps for cataract surgery, comprising medical stainless steel left and right tweezers 1, 2, the upper ends of the left and right tweezers 1, 2 are connected, and their lower ends are bent in the same direction and elastically open. The upper surfaces of the curved sections 3, 4 at the lower ends of the right tweezers 1, 2 are simultaneously or separately provided with a groove 5, 6 which can indicate the size of the capsulorhexis. The distance between the grooves 5, 6 and the tweezers of the corresponding left and right tweezers 1, 2 is about 5.5-6 millimeters, where 6 millimeters is the standard scale, and they can also be set at the same time.

The part not involved in the utility model is the same as the prior art or can be realized by adopting the prior art.

Claims (2)
