Design Of Thermal Cautery Device

Cauterization is a technique whereby a portion of tissues is burnt off for the purpose of closing the wound. It mitigates bleeding by destroying some tissues to reduce the risk of other possible injuries. Thermal cauterization uses heat for cutting of vessels, unlike the regular cutting with knife....
