Abstract
A microkeratome cutting-blade assembly 10 includes a cutting-blade 12 having a cutting edge 22 and apertures 18 within the blade 12. Each aperture 18 includes an inwardly-extending portion 20 on the side of the aperture 18 closest to the cutting edge 22. The assembly 10 includes a blade holder 14 having post members 16 configured to be received within the apertures 18. The cutting-blade 12 is attached to the blade holder 14 by staking the post members 16 received within the apertures 18. The cutting-blade's inwardly extending portions 20 cause the cutting-blade 12 to be maintained in accurate alignment while cold staking the post members 16 to expand and fill the apertures 18.
Claims19
A microkeratome cutting-blade assembly comprising:
- a cutting-blade having a cutting edge and apertures within the blade, each aperture including an inwardly-extending portion on the side of the aperture closest to the cutting edge;
- a blade holder having post members configured to be received within said apertures;
- and
- wherein the cutting-blade is attached to the blade holder by staking the post members received within the apertures.
A microkeratome cutting-blade comprising:
- a cutting-blade having a cutting edge thereon, and a plurality of apertures within the blade, each aperture including inwardly-extending portions on the side of the aperture closest to the cutting edge, wherein each aperture is configured to receive a post member of a blade holder therein.
A method of forming a microkeratome cutting-blade assembly comprising the steps of:
- positioning a cutting blade, which has apertures that include inwardly-extending portions on the aperture side closest to the blade's cutting edge, onto a blade holder having post members configured to be received within said apertures;
- and
- staking the cutting-blade to the blade holder to form a cutting-blade assembly, wherein the staking causes the post members to expand and fill gaps between the blade holder's post members and the cutting-blade's apertures.
