摘要： A system and method is disclosed for making incisions in the sclera of an eye to form a scleral pocket to receive a scleral prosthesis. The system and method comprises a surgical tool comprising a surgical blade for making incisions in the sclera of an eye. When a surgeon places the surgical blade on the sclera of the eye a pressure sensor in the surgical tool determines whether there is sufficient pressure between the surgical tool and the sclera of the eye for the surgical tool to operate properly. The surgeon activates the surgical tool to cause the surgical blade to advance through the sclera to form an incision having dimensions to receive a scleral prosthesis. When the incision is complete the surgical blade is rotated back out of the incision. The incision has the exact dimensions to receive a scleral prosthesis.

摘要： Surgical procedures and devices are used for treating medical conditions in the eye such as glaucoma. In particular, access to Schlemm's canal in the eye is obtained by cutting through a portion of the sclera to expose the canal. This incision may be made using a fixture that guides a microknife to make a precise cut. A catheter containing a knife may then be placed within Schlemm's canal, and the knife can be actuated to a position outside the catheter to allow an incision to be made. This incision may be made through the wall of the canal and into the surrounding trabecular meshwork, thereby improving the drainage of the aqueous humor from the eye and lowering the intraocular pressure.

摘要： A device (10) for fitting a cutting head (26) of a microsurgical cutting instrument, in particular a cutting instrument for use in refractive eye treatments, with a cutting blade unit, comprises a blade cartridge (12) which can be detachably coupled to the cutting blade holder (26) and in which a cutting blade unit is received. In addition, the fitting device comprises a slide (20) which is or can be held slidably relative to the cartridge and by means of which the cutting blade unit can be pushed out of the blade cartridge into a blade receiving pocket of the cutting head (26). Preferably, the slide (20) can be coupled to the cutting blade unit not only in a thrust-proof manner, but also in a traction-proof manner, so that after use the cutting blade unit can be withdrawn from the cutting head again by means of the slide (20) and guided back into the cartridge (12).

摘要： Disclosed is a corneal excision or scoring device. In one embodiment, the device includes a stabilizing portion having a first opening adapted to encircle an eye, such that at least a portion of the stabilizing portion engages the conjunctival fornix of the eye when inserted. The device may also include a second opening adapted to receive a cutting portion having a cutter capable of cutting or scoring the eye. In another embodiment, the device includes a stabilizing portion having an interior with a stop and an exterior serrated edge formed from a plurality of teeth. The stabilizing portion becomes inserted in an eye, such that the serrated edge rests on a sclera of the eye. Next, a cutting portion becomes inserted into the stabilizing portion to cut or score the eye, and the stop limits the distance the cutting portion may be inserted. Related methods are also disclosed.

摘要： A edged tool with a protective cover is provided, in which there is no necessity for mounting a member for locking a protective cover on a handle main body as a separate member, the protective cover for protecting a blade body can be easily manipulated by one hand and also the blade body can be retained in an exposing state and in a covering state. A surgical scalpel as the protective cover-equipped edged tool is provided with a grip portion formed so as to hold the handle main body by one hand and a supporting portion integrally coupled to the grip portion to support the protective cover so as to slide freely on the outer periphery. A projection is formed on the outer periphery of the supporting portion. A pair of locking portions with which the projection makes an elastic engagement when the protective cover is placed selectively at the covering position or at the exposing position are mounted on the protective cover.

摘要： A retractable safety knife has a hollow handle with an opening at an end thereof, a pusher that is movably disposed within the handle and is operable by a user, and a blade that is connected with an end of the pusher. When the pusher moves from a blade-retracted position to a blade-extended position, the blade extends outwardly from the handle opening and rotates from a nested position to an extended position.

摘要： 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.
