ABSTRACT:
A continuously conductive unipolar cannula for anesthesia is described with an electrically conductive cannula tube (10), with a tip (14) at the distal end and a body part (18) at the proximal end. The cannula tube (10) is provided with an outer electrically insulating covering, which leaves exposed only an end area (16) of the distal tip (14). In the area of the body part (18), an electrically contacting connection (22, 24, 26) for electro-stimulation is provided, which is provided radially on the outer circumference of the cannula tube (10). The body part (18) includes a guide inlet opening (32, 34) axially aligned with the cannula tube (10), through which a catheter can be introduced in the cannula tube (10). Alternatively, an injection hose or a needle can be connected to the body part (18).
