Description
Technical Field
The utility model relates to the technical field of medical appliances, in particular to three-piece type artificial lens loop implantation forceps convenient to implant.
Background
Intraocular lens haptic implantation forceps are a medical device used to implant intraocular lenses in cataract surgery. Such procedures are commonly used to treat cataracts, i.e., the lens of the eye becomes blurred or opaque, resulting in reduced vision.
During surgery, a surgeon may first use ultrasound or laser to break up the patient's lens and then implant an intraocular lens into the eye. Intraocular lenses are typically made of a foldable plastic sheet with three "haptics" (or struts) mounted thereon for fixation in place within the eye.
The existing YAMANE-scleral-interlayer suture-free fixation crystal haptic implantation forceps (shown in fig. 3) generally perform the operation of lens implantation and installation outside the eye, and rarely enter the eye, so that the clamping part is thicker and shorter, which is not beneficial to the operation in the anterior chamber eye, and the front end is of a flat design, which is only suitable for plate-type crystals, but is not beneficial to the clamping of YAMANE three-plate-type crystals (cylindrical), and is easy to slip and damage the crystal haptic, so that the three-plate-type artificial crystal haptic implantation forceps convenient to implant is provided.
Disclosure of utility model
Aiming at the defects of the prior art, the utility model provides three-piece type artificial lens implanting forceps convenient to implant, which solves the problems of inconvenient clamping, easy slipping and damage to the lens.
The utility model also provides three-piece intraocular lens implanting forceps convenient to implant, which comprise an implanting forceps body, wherein the implanting forceps body comprises a handheld part, a connecting part and a clamping part, the handheld part, the connecting part and the clamping part are integrally designed, the clamping part consists of a first clamping part and a second clamping part, the first clamping part and the second clamping part are columnar and are integrally L-shaped, a bending part formed between the first clamping part and the second clamping part is 140 degrees, a cylindrical groove is formed in the inner side of the tip end of the second clamping part, and an arc-shaped part is formed in the tip end of the second clamping part positioned at the front side of the cylindrical groove.
According to the three-piece intraocular lens implanting forceps convenient to implant, the length of the second clamping part is 13mm, and the width is 0.6mm.
According to the three-piece intraocular lens implanting forceps convenient to implant, the inner diameter of the cylindrical groove is 0.1mm.
According to the three-piece type intraocular lens implanting forceps convenient to implant, a round hole is formed in the hand-held portion.
The utility model has the following beneficial effects:
1. According to the utility model, the tip of the second clamping part is designed to be an arc-shaped part, so that the damage to eyes caused by the implantation forceps is avoided, the design of the cylindrical groove at the inner side of the tip is difficult to slide and damage the crystal loop during operation, and meanwhile, the width of the second clamping part is reduced, and the length is increased, so that the operation in the anterior chamber of the eyes is facilitated.
2. According to the utility model, the round hole is arranged on the hand-held part, so that the hand-held part has an anti-skid function, and meanwhile, consumable materials are reduced, and the cost is saved.
Additional aspects and advantages of the utility model will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the utility model.
