Description

Novel capsular bag ring cutter

Technical Field

The utility model relates to the field of novel medical equipment, more specifically relate to a novel intraocular capsule cutting knife of eye that is relevant with ophthalmology cataract operation more specifically, be the apparatus that combines together with tear bag auxiliary function.

Background

Cataract is a common blinding eye disease, which causes a rapid decrease in vision and ultimately blindness when the natural lens of the eye becomes clouded. Phacoemulsification and intraocular lens implantation are the most effective treatment options for cataract. With the continuous progress of science and technology, the way of cataract surgery is also changing. However, regardless of the cataract surgery, the capsulorhexis is one of the most critical steps in cataract surgery.

With the advent of high-end intraocular lenses (IOLs) in recent years, such as multifocal IOLs, astigmatic IOLs, infinitely variable focal IOLs, and the like. It is important to ensure good capsular bag neutrality of the implanted lens to reduce the appearance of poor postoperative vision (e.g., glare, starburst, etc.) in the patient.

If an off-center capsulorhexis occurs, on the one hand, the patient has an increased probability of poor visual quality after surgery and, on the other hand, a post-surgical cataract (PCO) occurs, and the post-surgical capsular bag shrinkage also significantly affects the patient's vision.

The existing capsulorhexis process is that the tip of capsulorhexis forceps directly enters the anterior chamber through a minimally invasive incision, the anterior capsule membrane is punctured, and then the anterior capsule membrane is pinched to carry out capsulorhexis operation. When the anterior capsule is not incised in advance, the capsule tearing forceps are directly used for puncturing the anterior capsule, so that the capsule tearing process becomes troublesome, the operation time is prolonged, and meanwhile, the capsule tearing effect is also greatly influenced.

Disclosure of Invention

The to-be-solved technical problem of the utility model lies in, to the problem that exists among the above-mentioned prior art, provide one kind and before tearing the capsule tweezers and get into, carry out a novel capsule ring cutter that a incision was handled in the middle of the bag earlier, come the supplementary completion and tear the bag process, through the cutting of novel capsule ring cutter, can be on intraocular lens capsule membrane light cut an anti "S" type the edge of a knife, the clamp that conveniently tears the capsule tweezers is got and is realized tearing the bag fast to guarantee the size and the circularity of bag.

The utility model discloses the technical scheme who adopts does: the utility model provides a novel cyst membrane ring cutter, includes handle of a knife and sword, there is the mark that is used for showing the cutting edge direction on the handle of a knife, the knife face of sword is anti "S" shape, and the knife face has certain angle, has the cutting edge of perpendicular to knife face on the knife face, cuts out the incision of anti "S" shape with the cyst membrane through pressing of cutting edge.

Preferably, the blade is reverse "S" shaped and has a width of 0.05-0.1 mm.

Preferably, the width of the reverse S of the knife is 0.5-2 mm, the length of the reverse S is 4.5-6 mm, and the bending angle of the knife is 30-60 degrees.

Preferably, the blade may be a single-sided or double-sided blade.

Preferably, the knife handle is provided with a raised mark, and the mark is perpendicular to the knife surface and opposite to the knife edge and is used for indicating the knife direction.

Preferably, the handle portion and the knife portion are connected by a transition handle with a radian.

Detailed Description

In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, a clear and complete description will be given below with reference to the technical solution of the embodiments of the present invention. The described parts are some embodiments of the present invention, not all embodiments, and all other embodiments obtained by those skilled in the art without any inventive work belong to the protection scope of the present invention.

The embodiment of the utility model is shown in fig. 1 to 5, and fig. 1 includes a 1-handle; 2-cutting. The graph of FIG. 2, which is obtained by partially enlarging the cutter portion, includes a 1-handle; 2-cutting; 3-knife edge. Fig. 3 and 4 show the relationship between the front view and the cross-section of the knife edge face.

In the implementation process, the novel capsular cutting knife is inserted through a minimally invasive surgery incision, and the center of the blade (3) is placed at the center of the capsular bag.

In the implementation process, as the thickness of the capsular bag is 0.02 mm-0.05 mm, only the capsular bag girdling knife needs to be lightly pressed to cut out a reverse S-shaped incision (6) on the capsular bag of the crystalline lens, then the capsular bag is annularly torn along the reverse S incision by using capsulorhexis forceps, and the tearing opening is torn along the extension of the reverse S incision, so that a circular hole with the diameter of 5-6 mm is formed. As shown in fig. 5.

It should be noted that, for those skilled in the art, without departing from the principle of the present invention, several modifications and applications can be made, and these modifications and applications are also considered as the protection scope of the present invention.
