Oscillating cast saws are generally used for cast removal and during the process the average blade temperature is around 56oC. Such a high temperature poses a risk of permanent thermal injury and the patient can suffer from second and third degree burns. Approximately, 7.2 per 1000 patients suffer from cast removal burns and injuries sustained during this process can cost one hospital around $15,000 per patient per year. Current cast saws do not have heat dissipation capabilities. The invention described here a cast removal blade which effectively and efficiently reduces the temperature of the blade thus reducing thermal injury.
