Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a three-piece artificial lens loop implantation forceps which is convenient for implantation. Background Art

[0002] An intraocular lens implant forceps is a medical device used to implant an artificial lens during cataract surgery. This surgery is often used to treat cataracts, which is when the lens of the eye becomes cloudy or opaque, causing decreased vision.

[0003] During surgery, the doctor uses ultrasound or lasers to break up the patient's lens, then implants the artificial lens, which is usually made of a foldable plastic sheet with three "haptics" (or support rods) that hold it in place inside the eye.

[0004] Existing YAMANE type scleral interlayer sutureless fixation lens loop implantation forceps (such as Figure 3 (As shown in the figure) The lens implantation and installation operation is usually performed outside the eye and rarely enters the eye. Therefore, the clamping part is relatively thick and short, which is not conducive to operation in the anterior chamber of the eye, and the front end is flat in design, which is only suitable for plate-type lenses. However, it is not conducive to clamping the YAMANE three-piece lens (cylindrical) and is easy to slip and damage the lens loop. Therefore, a three-piece artificial lens loop implantation forceps that is easy to implant is proposed. Utility Model Content

[0005] In view of the deficiencies of the prior art, the utility model provides a three-piece artificial lens haptic implantation forceps which is easy to implant, and solves the problems of inconvenient clamping, easy slipping and damage to the lens haptic.

[0006] The utility model also provides the above-mentioned three-piece intraocular lens haptic implantation forceps which are easy to implant, including an implantation forceps body, the implantation forceps body including a hand-holding part, a connecting part and a clamping part, the hand-holding part, the connecting part and the clamping part are of an integrated design, the clamping part is composed of a first clamping part and a second clamping part, the first clamping part and the second clamping part are both columnar and are L-shaped as a whole, the bending part formed between the first clamping part and the second clamping part is 140 degrees, a columnar groove is provided on the inner side of the tip of the second clamping part, and an arc-shaped part is provided on the tip of the second clamping part located in front of the columnar groove.

[0007] According to the three-piece intraocular lens haptic implantation forceps that are easy to implant, the second clamping portion has a length of 13 mm and a width of 0.6 mm.

[0008] According to the three-piece intraocular lens haptic implantation forceps which are easy to implant, the inner diameter of the cylindrical groove is 0.1 mm.

[0009] According to the three-piece intraocular lens haptic implantation forceps which are easy to implant, a round hole is provided on the handle.

[0010] The utility model has the following beneficial effects:

[0011] 1. In the utility model, the tip of the second clamping part is set as an arc-shaped part to avoid the implant forceps from causing damage to the eyes. The design of the cylindrical groove inside the tip makes it difficult to slide and damage the lens haptic during operation. At the same time, the width of the second clamping part is reduced and the length is increased to facilitate operation in the anterior chamber of the eye.

[0012] 2. In the utility model, a round hole is provided on the hand-held part to make it anti-slip, while reducing consumables and saving costs.

[0013] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS
