Abstract
The utility model discloses an intraocular artificial crystal scissors for ophthalmic surgery. The blades (2) of the intraocular artificial lens scissors are slender structures, diamond films are plated on the surfaces of the blades, and the outer sides of the front ends of the blades (2) are designed into smooth spherical structures (1). The utility model avoids the injury of other tissues such as corneal endothelium, iris, posterior capsule and the like in the operation of intraocular surgery. The surface of the leaf-cutting part is coated with a diamond film, so that the service life is prolonged. The utility model can enter the eye through the small incision without enlarging the incision, and has the advantages of flexible super-operation, convenient use, safe operation and reduced operation risk.
Description
Technical Field
The utility model relates to the field of ophthalmic surgery instruments, in particular to intraocular artificial lens scissors used in ophthalmic surgery.
Technical Field
In the cataract ultrasonic emulsification operation of ophthalmology, the incision of operation usually adopts 2.85-3.0 mm, and other doctors adopt 2.2-2.4 mm incisions. After the end of the super-breast surgery, a foldable intraocular lens with the diameter of 5.5-7.0 mm is implanted through the micro incision, and the intraocular lens automatically expands into the capsular bag after entering the eye.
When special conditions arise during surgery, for example: the artificial lens loop is broken, the optical area is damaged, and the like, or the degree of the implanted artificial lens is found to have errors after the operation. It is necessary to remove the intraocular lens from the eye and to re-implant a new intraocular lens.
The common method is as follows: the incision is enlarged to 3.5-4.0 mm, and then the intraocular lens is cut into two or three pieces by scissors and taken out.
At present, three types of ophthalmic microscissors are commonly used in clinic.
1. Conjunctiva scissors: the length is about 16 to 20mm, the leaf of the scissors is thick, the strength is high, but the incision needs to be enlarged to be inserted into the eye for operation, and side damage is increased. Moreover, the operation in the limited space of the anterior chamber of the eye is not flexible, and other tissues such as corneal endothelium, iris, posterior capsule and the like are easy to be injured.
2. Capsular scissors: the length is 12 to 16mm, and the length is slender, but the leaves are fine and have insufficient strength, so that the folded artificial lens is difficult to be cut off in the eye smoothly, and the leaves are easy to deform and damage.
3. Currently, current intraocular lens scissors: the leaf-cutting is also relatively thick and large, and needs to be enlarged to extend into the eye for operation, so that other tissues such as corneal endothelium, iris, posterior capsule and the like are easily injured. And the operation is not convenient and fast, and the side damage is easily caused.
Disclosure of Invention
In order to overcome the defects existing in the prior art, the utility model provides an intraocular artificial crystal scissors for ophthalmic surgery. The utility model has flexible operation, does not need to enlarge the incision, has spherical front end, and avoids injuring other tissues such as corneal endothelium, iris, posterior capsule and the like in the operation of intraocular surgery.
the utility model provides a technical scheme that its technical problem adopted is: the utility model provides an intraocular lens scissors for ophthalmic surgery, includes two scissors bodies, the scissors body includes leaf, handle and spring leaf, two scissors bodies pass through the hinge and articulate together, handle and spring leaf are same whole, superpose about the inboard cutting part of two leaf of cutting. The leaf-shaped scissors are in a slender structure, a diamond film is plated on the surface of the leaf-shaped scissors, and the outer side of the front end of the leaf-shaped scissors is designed into a smooth spherical structure.
The length of the leaf scissors is 11-13 mm.
The utility model has the advantages that: because the outer side of the front end of the leaf scissors is provided with the smooth spherical protective body, the injury to other tissues such as corneal endothelium, iris, posterior capsule and the like in the operation of intraocular surgery is avoided. The surface of the leaf cutting part is plated with a diamond film, so that the strength of the cutting edge of the intraocular artificial lens scissors for ophthalmic surgery is improved by three times. The utility model discloses in order to get into the eye through small incision, need not to enlarge the incision, super do in a flexible way, convenient to use, operation safety reduces the operation risk.

Detailed Description
Examples
Fig. 1 to 4 illustrate an embodiment of the present disclosure. Intraocular lens scissors includes two scissors bodies, and the scissors body includes scissors leaf 2, handle 4 and spring leaf 5, and two scissors bodies are together articulated through hinge 3, handle 4 and spring leaf 5 are same whole, and the inboard of one of them handle 4 sets up stop pin 6. The blade parts at the inner sides of the blades 2 of the two scissors bodies are vertically superposed. The utility model discloses a leaf-cutting 2 is the slender structure, its surface plating diamond film, the front end outside of leaf-cutting 2 is smooth ball shape structure 1.
The utility model provides an intraocular artificial lens scissors, it is long and thin to cut 2 leaf, and is long and thin than the conjunctiva scissors, and is sturdy than the cyst membrane scissors, and is fine nimble promptly, has certain intensity again. The length of the leaf scissors 2 is 12mm, the leaf scissors can extend into eyes through an operation incision of 2.2mm, the opening and the closing are free, the operation is flexible, and the incision does not need to be enlarged. The outer side of the front end of the leaf scissors 2 is designed into the smooth spherical protective body 1, so that the injury of the tip to other tissues such as corneal endothelium, iris, posterior capsule and the like in the operation of intraocular surgery is avoided. Leaf 2 was cut with a diamond film and the strength was increased by three times. The artificial lens is easier to cut, and the artificial lens is cut into three to four pieces to be smoothly taken out of the eye.
The above-described embodiments are not intended to limit the present invention, and modifications and equivalent variations made by those skilled in the art based on the essence of the present invention are within the technical scope of the present invention.
