Detailed Description
The utility model is further illustrated in the following, in conjunction with the accompanying drawings and examples. In the following detailed description, certain exemplary embodiments of the present utility model are described by way of illustration only. It is needless to say that the person skilled in the art realizes that the described embodiments may be modified in various different ways without departing from the spirit and scope of the utility model. Accordingly, the drawings and description are to be regarded as illustrative in nature and not as restrictive in scope.
As shown in fig. 1, 2, 3 and 4, intraocular lens implantation forceps are used to take and implant an intraocular lens 8 into an eye when an intraocular lens 8 implantation procedure is performed. The intraocular lens implantation forceps comprise two implantation forceps handles 1, wherein one ends of the two implantation forceps handles 1 are elastically connected, and the other ends of the two implantation forceps handles are arranged in a separated state so as to facilitate forceps clamping the intraocular lens 8. Each implantation forceps handle 1 is gradually narrowed from the middle part to the end part of the separated side, the separated ends of the two implantation forceps handles 1 are respectively and fixedly connected with an implantation connecting handle 2, the end parts of the two implantation connecting handles 2 are correspondingly and fixedly provided with implantation forceps holding plates 3 for holding the intraocular lens 8 in a matched manner, and when the intraocular lens forceps are used, the distance between the two implantation forceps holding plates 3 is changed by utilizing the two implantation forceps handles 1 so as to facilitate forceps to take the intraocular lens 8 and implant the intraocular lens into eyes.
The implantation forceps holding plate 3 includes a forceps holding straight plate portion 31 fixedly connected with the bottom or the side portion of the implantation connection handle 2, a forceps holding arc plate portion 32 is integrally formed at the end portion of the forceps holding straight plate portion 31, and concave intrados of the forceps holding arc plate portion 32 of the implantation forceps holding plate 3 are oppositely arranged. The diameter of the two forceps holding arc plate parts 32 after being closed is 2.6-3.8 mm, and the intraocular lens 8 is held by forceps so as to be limited between the two forceps holding arc plate parts 32, thereby preventing the intraocular lens from falling off in the moving process. And the two forceps holding arc plate parts 32 can enclose a space in a closed state, so that a first layer of forceps holding protection is formed for the intraocular lens 8, and the intraocular lens 8 is prevented from being damaged due to excessive forceps holding. And the two surfaces of the forceps holding straight plate part 31 and the forceps holding arc plate part 32 are respectively in arc surface transitional connection, so that the surfaces of the forceps holding straight plate part and the forceps holding arc plate part are smooth, and the forceps holding straight plate part and the forceps holding arc plate part are prevented from scratching intraocular tissues after entering eyes, so that the forceps holding straight plate is safer to use.
In this embodiment, the outer top end of each implantation connection handle 2 is provided with a thickness-reducing inclined plane 4 which is convenient for intraocular operation, so that the overall thickness of the operation end, i.e. the implantation connection handle 2 and the forceps arc-holding plate portion 32, can be reduced to a certain extent, and the forceps arc-holding plate portion is more suitable for use in a narrow intraocular space. And the thickness-reducing inclined plane 4 is in smooth transitional connection with the top surface and the end vertical plane of the implantation connecting handle 2 respectively, so that sharp edges or sharp angles are prevented from occurring at the part of the implantation forceps entering the eyes, the probability of scratching the tissues in the eyes is further reduced, and the risk of causing complications is reduced. And the implantation connecting handle 2 is arranged obliquely upwards and outwards, and an operation included angle 5 which is convenient for observation is formed between the implantation connecting handle and the corresponding implantation forceps handle 1, so that the exposure degree of the operation point in the field of vision of a doctor is increased to a certain extent, and the operation observation effect is better and more convenient.
In this embodiment, a forceps holding limiting post 6 extending toward the other forceps handle 1 is fixedly disposed on the inner side wall of one of the forceps handles 1. Namely, in a natural state, one ends of the two implantation forceps handles 1, which are used for forceps holding the intraocular lens 8, are in a separated state, and the forceps holding limiting column 6 is not contacted with the other implantation forceps handles 1; when the two implantation forceps handles 1 are forced, the intraocular lens 8 is held by the forceps of the two implantation forceps holding plates 3, the forceps holding limiting columns 6 are abutted against the surface of the other implantation forceps handle 1, so that a certain distance is always reserved between the two implantation forceps holding plates 3, the intraocular lens 8 is prevented from being damaged due to excessive clamping, and a second layer of protection for the intraocular lens 8 is formed. The anti-skid patterns 7 are respectively arranged on the outer surfaces of the two implantation forceps handles 1, so that the friction force between the hands and the two implantation forceps handles 1 can be increased, and the forceps holding and implantation operation of the intraocular lens 8 are more stable.
As shown in fig. 5, when in use, the two forceps holding arc plate parts 32 are placed on two sides of the intraocular lens 8, the two forceps holding arc plate parts 32 are forced to be smaller or even be combined together, the intraocular lens 8 is held in the hollow inner cavity enclosed by the forceps holding arc plate parts 32, after the intraocular lens 8 is implanted into the eye, the pinching of the two forceps holding arc plate parts 1 is properly released, and the intraocular lens 8 can be placed in the eye, thus completing the implantation operation.
The description of the present utility model has been presented for purposes of illustration and description, and is not intended to be exhaustive or limited to the utility model in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments were chosen and described in order to best explain the principles of the utility model and the practical application, and to enable others of ordinary skill in the art to understand the utility model for various embodiments with various modifications as are suited to the particular use contemplated.
