Abstract
The utility model discloses a corneal knife blade which is comprised of a slice knife body (1) whose blade (3) surface is provided with a layer of diamond like film (5), and the knife body (1) is equipped with an installing hole (2) which can be fixed in the corneal cutting head. The corneal knife blade of the utility model has advantages of high intensity, high rigidity and sharp blade, and moreover, is wearable, rustproof and dizzy resistant, and has smooth surface and small friction coefficient. Besides, the corneal knife blade simplifies production and prolongs the service life, thereby applying to massive production.
Description
Technical field
This utility model relates to a kind of medical equipment, especially relates to a kind of corneal lamellar cutter blade.
Background technology
At present, the excimer laser refraction correction surgery is adopted widely by people.Wherein, Laser in Situ Keratomileusis (LASIK) is the novel operation that occurs on the PRK basis.
Lasik surgery, be to adopt accurate cornea lamellar blade in the cornea flap (comprising corneal epithelium, bowman's lamina and shallow-layer corneal stroma) of doing the band base of a fruit about thick about a 0.13～0.16mm on the cornea, corneal stroma bed under lobe carries out laser cutting, then cornea flap is resetted.Its biggest advantage is to have kept corneal epithelium and anterior elastic membrane, therefore, does not almost have the corneal opacity phenomenon of seeing after the PRK operation.And postoperative reaction is extremely light, and the patient does not almost have significant discomfort, and vision restoration is fast, and complications of regression is few.
The corneal lamellar cutter blade be installed on carry out on the cornea lamellar blade matching used.Because lasik surgery requires corneal lamellar cutter blade hardness and intensity height, and is very sharp.So people are making great efforts to improve intensity, hardness, the increase wearability of corneal lamellar cutter blade always, improve service life.
In addition, also there is blade face brightness height in present corneal lamellar cutter blade, and dazzle is arranged, and the doctor increases the fatigue strength of eyes in operation easily; Shortcomings such as the blade face Corrosion Protection is poor.
The utility model content
The purpose of this utility model is: a kind of corneal lamellar cutter blade is provided, and its intensity hardness height, wear-resistant, cutting edge is sharp.
The technical solution of the utility model is: a kind of corneal lamellar cutter blade, and it comprises a laminar cutter hub, the edge surface of cutter hub is provided with one deck diamond like carbon rete.
Below technique scheme is further explained:
1. described diamond like carbon rete is a cathodic sputtering diamond like carbon rete.
2. the blade surface of described cutter hub also is provided with one deck diamond like carbon rete.That is, whole cutter hub (comprising cutting edge part and blade part) is provided with one deck diamond like carbon rete.
3. the diamond like carbon rete in the above-mentioned explanation 2 is a cathodic sputtering diamond like carbon rete.
4. described cutter hub is provided with the installing hole that can be installed in the cornea lamellar blade cutting head.During the supporting use of corneal lamellar cutter blade and cornea lamellar blade, the corneal lamellar cutter blade is installed in the cornea lamellar blade cutting head, and cornea lamellar blade has a motor eccentric shaft to insert in the corneal lamellar cutter blade installing hole, installs with unique correct position guaranteeing.
5. described cutter hub is rectangle.
6. described cutter hub is trapezoidal.
7. described cutter hub is at right angles trapezoidal.
The utility model has the advantages that:
1. corneal lamellar cutter blade of the present utility model has the intensity height, the hardness height, and cutting edge is sharp, and is wear-resistant, corrosion-resistant, anti-dazzle, smooth surface, the advantage that coefficient of friction is little, and easy to process, long service life can be produced manufacturing in enormous quantities.
2. corneal lamellar cutter blade of the present utility model, its diamond-film-like (DLC) is a black, effectively prevents the working head dazzle, makes the ophthalmologist in use feel more comfortable, and is not tired.
3. corneal lamellar cutter blade of the present utility model, its diamond-film-like (DLC) adopt the cathodic sputtering mode to be provided with, and the adhesion with rete and base material is strong, rete densification, advantage such as even.
