Abstract

A single use corneal marker for use in corneal transplant surgery made from a disposable material as opposed to metal, thus allowing its use in areas where sterilisation is not readily available and areas sensitive to the presence of HIV and CJD. The instrument comprises a ring fixed to a handle wherein the ring has a series of curved blades and a needlepoint indicating its centre. In use, the blades are pressed onto a pad of gentian violet and then onto the corneal surface to leave indentations and ink stains.

Description

DESCRIPTION SINGLE USE DISPOSABLE CORNEAL MARKER A set of single-use disposable cornea ! markers.
Comeal markers are used in surgery to cause pressure on the cornea which thus induces lines to permit the surgeon to identify the approximation of the wound. The instrument is sometimes used to carry"ink"to more clearly define the pressure marks.
At present surgeons use steel or titanium corneal markers which are expensive, and for which there is no patent.
According to the present invention, there is provided a single use disposable surgical instrument for marking the cornea.
The instrument has been designed for use in corneal transplant surgery where the cornea of a patient has deteriorated to the extent that it warrants replacement with a cornea from a donor eye.
The instrument is a hand-held device which has a ring fixated on to a handle. It is available with a variable angled head. The ring has a series of curved blades radiating from the ring which also has a needlepoint which indicates the centre of the ring. The instrument is held down on to a pad of marking ink of gentian violet and transported onto the patient's cornea via the blades.

Claims (7)

  1. CLAIMS 1. A single-use disposable surgical instrument for marking the cornea.
  2. 2. It has the same characteristics as a metal corneal marker; however, being made of disposable material it is therefore cheaper and more hygienic.
  3. 3. Because it is disposable it can be used in the field where sterilisation of surgical instruments is not available.
  4. 4. The instrument contains the same properties as the metal type but it is less expensive and especially suitable in areas sensitive to the presence of HIV or CJD diseases.
  5. 5. The mark that the instrument makes serves to assist the surgeon to identify the surface zone of the cornea to assist in the approximation of the donor cornea in corneal trephination and allows for better approximation of the donor cornea button.
  6. 6. The instrument assists the surgeon to approximate the placement of the donor cornea. It has been established over the last several years that accurate approximation can materially affect the post-operative results for the patient.
  7. 7. The instrument can have a variable angled head allowing for surgeon preference.
