Cleaning Swann-Morton Skin Graft Handles / Dermatome

Care, Handling and Reprocessing of Swann-Morton Skin Graft Knife Handles / Hand-operated Dermatome

Surgical instruments are designed to perform many specific functions. The use of any instrument for tasks other than those for which they are intended may result in damage or breakage. The proper cleaning, handling and sterilisation procedures will ensure that your surgical instrument will perform as intended and extend its useful life.

How Supplied

The instrument is supplied non sterile and must be cleaned and sterilised prior to use according to the procedures outlined in this document, unless stated otherwise with the packaging of the product.

Inspection & Function Testing

Visually inspect and check the instrument for damage and wear after each cleaning and disinfecting cycle; articulated instruments have a smooth movement without excess play; locking mechanisms (such as ratchets) fasten securely and close easily; long slender instruments are not distorted. Do not use and remove for repair or replacement any worn out, fractured or damaged instruments.

Precautions

Delicate surgical instruments require special handling to prevent damaging. Use caution during cleaning and sterilisation. A non fibrous sponge should be used to wipe off all blood and surgical debris. Do not apply excessive stress or strain to the joints, misuse will result in damage. Do not apply excessive stress during use. Instruments manufactured of different metals should be processed separately to avoid electrolytic action between the different metals.

Care & Handling

The procedures outlined below are recommended to ensure safe handling of biologically contaminated surgical instruments. All instruments must be sterilised before use. NOTE: When reprocessing medical devices always follow local Health & Safety procedures.

Warnings

Follow instructions and warnings as issued by manufacturers of any decontaminants, disinfectants and cleaning agents used. Wherever possible, avoid use of mineral acids and harsh, abrasive agents. No part of the process shall exceed 140 degrees C. Some sensitive materials can be damaged by higher alkaline solutions, (pH >10). Devices with long hinges and blind holes require particular attention during cleaning. Note: Single use devices must not be reprocessed and reused.

Limitations on Reprocessing

Repeated processing has minimal effect on stainless steel surgical instruments. End of life is normally determined by wear and damage in use.

Pre - Cleaning

Wherever possible, do not allow blood, debris or bodily fluids to dry on instruments. For best results and to prolong the life of the medical device reprocess as soon as it is reasonably practical following use. If they cannot be reprocessed immediately, use an enzymatic cleaner to help prevent soil from drying.

Cleaning (Cleaning Precautions)

Do not soak instruments in hot water, alcohol, disinfectants or antiseptics to avoid coagulation of mucus, blood or other bodily fluids. Do not use steel wool, wire brushes, pipe cleaners or abrasive detergents.

  • Do not scratch or otherwise damage the adjustable guide rod with other instruments.
  • Make certain that the adjustable guide rod is not bent or damaged by heavy objects or instruments.
  • Avoid moving the instrument forcefully or vibrating.
  • Make certain that the guide rod is firmly fixed in place during the entire application.

BRAITHWAITE AND COBBETT MODELS

The guide rod is mounted in two support arms and is held in place by screws.

  • Make certain that the support arms are screwed securely in place and that there is no play between the guide rod and support arms.

WATSON MODELS

The guide rod is mounted in two support arms and is stopped with a nut.

  • Make certain that the nut is absolutely flush with its counterpiece and that there is no play between the guide rod and support arms.

SILVER MODEL

Implant thickness is adjusted with the aid of two screws each of which is mounted in a bearing support.

  • Make certain that there is no play between bearing supports and screws.

Assembling

In order for the hand-operated dermatome/skin graft knife to function properly, pressure must be evenly distributed over the entire length of the blade. This can be achieved only if the procedure described below is applied:

  • In order to avoid damaging the blade, set the guide rod so that it is as far away as possible from the blade.
  • Insert the blade precisely in the mounting that is provided for it.
  • Fix the blade in place with the tensioning plate.

Disassembling

WARNING: Risk of injury from sharp blade!

  • Remove blade carefully.
  • Avoid damaging the edges of either the base plate or tensioning plate.
  • Do not use hard or metallic objects to remove the blade.
  • Discard Blade in used sharps container.
