Abstract
The invention discloses a novel temperature-adjustable scalpel which comprises a blade shell, multiple heating elements and an insulating packaging layer, a coating and a heating and inductive microcircuit arranged on the inner layer of a blade of the blade shell. The heating elements are arranged in the blade shell and packaged through the insulating packaging layer. The insulating packaging layer is coated with the coating. Electric/thermal converters are adopted to serve as the heating elements, so that the electric heat conversion efficiency is improved, temperature compensation and the large thermal capacity are achieved rapidly, the tissue bonding resistant function is achieved, insulating packaging processing is enhanced, and reliability is extremely high. By the adoption of the heating and inductive microcircuit, the application range is wide, the scalpel is not prone to disturbance caused by external environment, the temperature sensing area is large, temperature closed-loop control can be achieved by the scalpel and a micro-processing system of a host computer of an electric surgical operation system, and therefore the purpose of accurate temperature control is achieved.
