Bakulev needle

Bakulev needle - (A.N. Bakulev, 1892-1970, Soviet surgeon) Is a vascular wire for intravascular surgical manipulations.

Proposed by Doctor of Medical Sciences, Academician Alexander Nikolaevich Bakulev in 1946 and named after him. The needle device is much simpler than a regular injection needle and looks like a metal tube with corkscrew-shaped or spiral cuts along its entire length. These design features increase the strength of the spoke during its deformation or fracture, as they give it additional rigidity. Due to this, deformation occurs not when the loop is pushed into the puncture point, but already at the moment of bending the needle for the next stage of the surgical intervention. Thus, the doctor can be sure in advance that the needle will break exactly where it is needed, and will modify it in the process. The vascular wire has a universal type of sharpening of the spiral end and geometric parameters that allow manipulation from both the femoral and main arteries. The size and type of sharpening of the needle can be varied depending on the diameter, shape and location of the artery that needs to be punctured. The thickness of the needle allows for the necessary manipulations. The standard needle sizes are 6 Fr (circumference diameter 2.2 mm for the body) and 5 Fr (for the periphery), as is the length of the spiral 4 cm. The baculeva wire can also have a special needle device - an aspirator, which creates negative pressure on the lumen of the vessel, thereby facilitating the advancement of the needle during puncture. An important advantage is that aspiration is carried out without additional needle placement
