摘要:
The present invention relates to a cannula for femoral arterial bidirectional (a heart direction and a distal lower extremity direction) perfusion. The cannula, which has a cannula tube to be inserted into a blood vessel of the femoral artery, includes a perfusion guide channel formed as a concave part from a predetermined portion of an inner circumferential surface at an end of the cannula tube to the opposite end thereof in a length direction and further includes a through-hole provided at a boundary portion between the perfusion guide channel and the cannula tube in an end direction of the cannula tube, or includes a through-hole provided in a predetermined portion of an inner circumferential surface of an end of the cannula tube and a guide cover provided at an upper portion of the through-hole to cover the upper portion of the through-hole and guide perfusion. During surgery, perfusion proceeds towards the distal limb and thus blood may be stably supplied, and thus ischemia prevalence of the distal limb may be significantly reduced. Accordingly, the cannula can replace conventional techniques used for distal limb perfusion and may stably perform femoral arterial cannulation without technical difficulties such as complications or breakage of blood vessels.
