Cautery hemostatic unit

摘要

This unit is for stopping hemorrhage by supplying a current for heating to a semi-conductive thermal element of small heat capacity to insure good heat response which is incorporated in the distal extremity of a slender probe, and possesses a means to recognize whether, or not, voltage fall between the both ends of the thermal element is within the permissible range in order to make it possible to detect qualitative deterioration of thermal element.
