Instrumentsæt til anæstesi

A set of instruments for anaesthesia consists of a straight epidural cannula (10) with bevelled opening (16), a spinal cannula (20) which is longer and thinner than the epidural cannula (10) and can be pushed into the latter in such a way that its front end projects beyond the epidural cannula (10), and a catheter (30) which can be pushed through the epidural cannula (10). According to the invention, the tip (13) of the epidural cannula (10) is curved and the opening (16) is directed sideways, and in the outer wall (14) of the curvature of the tip (13) there is a hole (17), which is centered on the longitudinal centre axis of the epidural cannula (10) and is smaller than the external diameter of an epidural catheter (30). The three-component instrument set is easy for the user to operate, since the tip of the spinal cannula (20) is forced to enter the vertebral canal in a rectilinear fashion, and the epidural catheter (30) is forced away from the vertebral canal and introduced into the epidural space. Spinal anaesthesia and catheter-epidural anaesthesia are carried out in conjunction without special skill.
