Available in three distinct models: Braithwaite, Cobbett, and Watson, these Stainless Steel Handles are designed for use with the sterile 158mm Skin Graft Blades to facilitate the harvesting of "Macro" or "Major" Skin Grafts. Each handle features an adjustable guard that controls the maximum thickness of the graft based on the skin characteristics at the donor site, which can vary due to factors such as the patient's age.
The precise thickness of the graft is influenced by:
1) The angle of contact between the blade and skin during harvesting;
2) The amount of pressure the operator applies to the handle during the procedure.
Mastering these elements of the skin grafting technique is crucial for consistently achieving high-quality split thickness skin grafts.
The Braithwaite Handle, introduced by Fenton Braithwaite in 1955, improved upon the Humby and Bodenham Knives by eliminating the need for disassembly to change the blade. Adjustments between the roller and blade are made using two knurled collars located on the handle's back. The stainless steel blade is securely held in place by a leaf spring holder. To replace the blade, the safety catch is moved to open the leaf, allowing the blade to be inserted under the roller before reengaging the safety catch. When cutting thin split skin grafts with the Braithwaite Handle, skin may roll around the guard, but this can be managed by applying traction to the cut skin to prevent tearing. The roller must move freely from side to side, requiring loose end-bearings that can affect precision, sometimes causing the graft to thicken as the handle advances. Two adjustments at each end of the handle are needed to set the cutting depth, and if these settings are uneven, the graft may be thicker on one side.
