The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

Example one

As shown in fig. 1 to 5, the utility model provides a pair of special scissors for artificial lens, include: the left cutter body 100 is hinged to the right cutter body 200, one end of the left cutter body 100 is hinged to one end of the right cutter body 200, the other end of the left cutter body 100 is connected with the other end of the right cutter body 200 in an inserting mode, wherein the left cutter body 100 comprises a left cutter head portion 110, a left cutter handle portion 120 and a left spring leaf 130, the left cutter handle portion 120 and the left cutter head portion 110 are integrally arranged, the left spring leaf 130 is connected to the left cutter handle portion 120, the right cutter body 200 comprises a right cutter head portion 210, a right cutter handle portion 220 and a right spring leaf 230, the right cutter handle portion 220 is integrally arranged with the right cutter head portion 210, the right spring leaf 230 is connected to the.

In the present embodiment, since the left and

right cutter bodies

100 and 200 have the same structure, the following description will be made without distinguishing the structure of the left cutter body 100 from the structure of the right cutter body 200, and the components thereof are collectively referred to as a head portion, a shank portion, and a spring piece.

In the intraocular lens scissors of the present embodiment, the shearing force between the left blade portion 110 and the right blade portion 210 is generated by the elastic compression between the left spring plate 130 and the right spring plate 230, and can be inserted into the eye at a surgical incision of 2.2mm or more without enlarging the incision. In addition, the hinged part of the left cutter body 100 and the right cutter body 200 is located at the junction of the cutter head part and the cutter handle part, and the insertion part of the left cutter body 100 and the right cutter body 200 is located at the connection part of the left spring piece 130 and the right spring piece 230. The width dimension of the hinged part is smaller than that of the surgical incision, so that the cutter head part of the artificial lens scissors can smoothly extend into the surgical incision for lens shearing operation.

The utility model provides a pair of special scissors of intraocular lens is serration structure with the cutting edge 300 setting of one of them sword head portion for medical personnel can be fixed effectively when cuting the crystal operation, the condition of avoiding taking place the crystal slippage, improve and cut reliability and convenience, in addition, the cutting edge 300 that sets up serration structure can effectively solve the crystal slippage and cause the problem of intraocular tissue damage such as corneal endothelium, iris, back sac membrane.

Further preferably, when the blade 300 of the left bit portion 110 is serrated, the blade 300 of the right bit portion 210 is smoothly straight; when the cutting edge 300 of the right blade head portion 210 is serrated, the cutting edge 300 of the left blade head portion 110 is smoothly straight.

It is further preferable that the section of the serrated blade 300 is in a triangular structure, or in a trapezoidal structure, so as to further achieve the fixing effect of the crystal when shearing.

Further preferably, the blade 300 of the blade head is made of diamond, and the diamond has high hardness and good wear resistance, so that the manufactured artificial crystal scissors can cut the crystal more easily.

Further preferably, the point of each nose portion is provided with a rounded corner 111. In this embodiment, if the tip of the blade head of the intraocular lens scissors is formed in a sharp-angled configuration, it is easy to damage the intraocular tissues such as the corneal endothelium, iris, and posterior capsule during cutting the lens, and in this embodiment, the tip of the blade head of the intraocular lens scissors is formed in a rounded-corner 111 configuration, which can prevent the intraocular tissues such as the corneal endothelium, iris, and posterior capsule from being damaged during cutting the lens.

Further preferably, both ends of the rounded corner 111 are tangent to the inner and outer sides of the head (the blade 300 and the back).

Preferably, as shown in fig. 1 to 5, the shank portion is arranged in a linear structure, wherein a concave-convex structure is arranged on one side of the shank portion, and a smooth linear structure is arranged on the other side of the shank portion.

In this embodiment, set up concave-convex structure with one side of handle of a knife portion, form anti-skidding line for medical personnel when using artificial crystal to cut the operation to the crystal, increase medical personnel's finger (medical gloves after the disinfection) and the artificial crystal and cut the frictional force between, further improve the maneuverability and the security of operation.

Further preferably, in the concave-convex structure on the shank portion side, the concave portion 400 and the convex portion 500 are provided with a gap therebetween. Due to the structural arrangement, the friction force between the fingers of the medical staff and the anti-skid lines is more uniform, and the anti-skid effect is better.

Further preferably, in the concave-convex structure on the shank portion side, the lateral width of the concave portion 400 is larger than the lateral width of the convex portion 500. In the embodiment, the transverse width of the convex part 500 is set to be smaller, and the transverse width of the concave part 400 is set to be larger, so that when the fingers of the medical staff contact the intraocular lens scissors, the fingers first contact the convex part 500, and the friction force between the fingers and the convex part 500 comes from the extrusion force generated by the extrusion of the left spring piece 130 and the right spring piece 230, if the transverse width of the convex part 500 is smaller, the friction force between the fingers and the convex part 500 is larger, and if the transverse width of the convex part 500 is larger, the fingers and the convex part 500 easily slip, so that the friction force between the fingers and the convex part 500 is reduced, and the safety of the hospital staff in the process of performing the lens scissors operation is influenced.

Further preferably, a cutout 600 is provided on the smooth straight side of the handle, wherein the cutout 600 cuts through the recess 400 of the handle. In this embodiment, set up hollow out construction 600, the weight of sword stalk portion can be reduced on the one hand, operation when making things convenient for hospital personnel to perform the operation, on the other hand increases the elasticity of sword stalk portion, and then increases the frictional force between medical personnel's finger and the handle of a knife portion.

Example two

As shown in fig. 6, the present embodiment is different from the present embodiment in that, in the present embodiment, the blade 300 of the left blade head portion 110 and the blade 300 of the right blade head portion 210 are both provided with a saw-toothed structure, and the blade back of the left blade head portion 110 and the blade back of the right blade head portion 210 are both provided with a smooth straight line. Thereby further improve medical personnel's fixed effect when cuting the crystal, improve the security that the crystal was cuted, cut the intraocular lens of embodiment one and the intraocular lens in embodiment two and cut, realize the shearing of different crystal thickness, improve the flexibility that the intraocular lens cut and use.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications or additions may be made to the described embodiments or alternatives may be employed by those skilled in the art without departing from the spirit or ambit of the invention as defined in the appended claims.
