Abstract
The invention discloses bend-type crystal implanting forceps. The forceps comprise forceps handles, forceps points and a forceps tail, wherein the forceps points and the forceps tail are arranged at the two end parts of the forceps handles respectively; first holes, second holes and cushion pads are formed in and arranged on the forceps handles; the cushion pads are arranged on the inner side surfaces, at the ends near the forceps points, of the forceps handles; the forceps points are provided with bends and bending arms; the bends adopt a circular arc-shaped structure; the bending arms adopt a straight pole structure; smooth insections are formed in the inner side surfaces of the bends. Through the adoption of the technology, conventional pointed cones are modified into the smooth bend structure, so as to reduce potential safety hazard existing in operation to a certain extent; meanwhile, the smooth structures are arranged on the inner side surfaces of the bend structures, so as to protect crystal from damaging, and improve clamping force of friction moderately; the practicability of the device is improved by forming and arranging the holes and the cushion pads on the forceps handles; the goals of reducing operation risk and improving work efficiency are achieved eventually.
Description
Technical field
The present invention relates to medical instruments field, particularly relate to a kind of curved head type Lens implantation tweezer.
Background technology
Intraocular lens is the most effective method correcting aphakia refraction of eye at present, it is in dissection and optically instead of original crystalline lens, constitute an approximate normal system, be especially fixed on the posterior chamber intraocular lens in crystalline lens physiological location.Can be used for simple eye, and postoperatively can recover vision rapidly, easily set up binocular single vision and stereoscopic vision.
At present, in lens insertion procedure, often use Lens implantation tweezer, by this Lens implantation tweezer, artificial intraocular lenses is clamped, thus be placed into the position of needs; But the tip of existing Lens implantation tweezer is sharp pointed cone structure, although this kind of structure can realize locating accurately, due to the sharpness of its tip, very easily certain damage is caused to the ocular tissue of fragility, thus cause very serious consequence.
Summary of the invention
In order to solve above-mentioned safety problem, the invention provides a kind of curved head type Lens implantation tweezer, by have modified existing prong structure, the potential safety hazard existed in operation can be effectively reduced.
Above-mentioned a kind of curved head type Lens implantation tweezer, comprise tweezer handle, tweezer point and tweezer tail, described tweezer point and tweezer tail lay respectively at two ends of tweezer handle, wherein, described tweezer handle is provided with the first hole, the second hole and cushion pad, described first hole is positioned at the middle part of tweezer handle, and described second hole is positioned at the end of tweezer handle, and described cushion pad is positioned at the medial surface near tweezer point one end on tweezer handle;
One end away from tweezer handle on described tweezer point is provided with elbow and bent over arms, and described elbow is arc-shaped structure, and described bent over arms is straight-bar structure, and the medial surface of described elbow is provided with intensive level and smooth groove.
In said apparatus, the quantity of described first hole and the second hole is 2.
In said apparatus, the diameter of described first hole is greater than the diameter of the second hole.
In said apparatus, described tweezer handle, tweezer point and tweezer tail are stainless steel structure.
In said apparatus, described cushion pad is rubber blanket.
Advantage of the present invention and beneficial effect are: the invention provides a kind of curved head type Lens implantation tweezer, by existing pointed cone is improved as smooth elbow structure, thus reduce the security hidden trouble existed in operation to a certain extent; Simultaneously; smooth structure is provided with at the medial surface of elbow structure; thus the friction dynamics increasing clamping suitable while protection crystal is injury-free; and the practicality of device is increased by being provided with 4 holes and 1 cushion pad on tweezer handle, finally reach objects such as reducing operation risk, increase work efficiency.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of curved head type Lens implantation tweezer in the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
Fig. 1 is the structural representation of curved head type Lens implantation tweezer in the present invention; As shown in Figure 1, this invention describes a kind of curved head type Lens implantation tweezer, comprise tweezer handle 1, tweezer point 2 and tweezer tail 3, and tweezer point 2 and tweezer tail 3 lay respectively at two ends of tweezer handle 1.
Wherein, above-mentioned tweezer handle 1 is provided with the first hole 11, second hole 12 and cushion pad 13, be specially: the first hole 11 is positioned at the middle part of tweezer handle 1, and the second hole 12 is positioned at the end of tweezer handle 1, the medial surface near tweezer point 2 one end on tweezer handle 1 is positioned at as cushion pad 13, this cushion pad 13 primary responsibility alleviates the impulsive force between two tweezer handles 1, preferably, in order to reach better buffering effect, cushion pad 13 in the present invention have employed rubber blanket, the quantity of the first hole 11 and the second hole 12 is 2 simultaneously, and the diameter of the first hole 11 is greater than the diameter of the second hole 12, so that the structure narrow with two ends wide in the middle part of tweezer handle 1 matches.
In addition, tweezer point 2 is provided with the elbow 22 of arc-shaped structure and the bent over arms 21 of straight-bar structure away from one end of tweezer handle 1, and the elbow 22 round and smooth by this can effectively reduce the security hidden trouble existed in operation; Simultaneously; in order to avoid during clamping, crystal is caused damage; so be also provided with very intensive level and smooth groove 221 at the medial surface of elbow 22; because the dense degree of groove is larger; its surface is just all the more smooth; thus reach under the injury-free prerequisite of protection crystal, suitable friction dynamics when adding clamping, and then improve the convenience of operation.
Preferably, the tweezer handle 1 in the present invention, tweezer point 2 and tweezer tail 3 all have employed stainless steel structure, and avoid the liquid such as the blood touched in operation to the corrosion of device with this, thus add the ruggedness of device.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
