METHOD OF ARTHROSCOPIC RECONSTRUCTION OF POSTERIOR CRUCIATE LIGAMENT AND SET OF INSTRUMENTS FOR PROTECTION OF POPLITEAL ARTERY IN COURSE OF ITS REALISATION Russian patent published in 2015 - IPC A61B17/56 

FIELD: medicine.

SUBSTANCE: group of inventions relates to traumatology and orthopaedics. A set of instruments for the protection of the popliteal artery in the operation of arthroscopic reconstruction of the posterior cruciate ligament includes a guide-pin, which is sharpened from both ends, with a sharpening from one end being trihedral; the device for the protection of the popliteal artery, consisting of a working part and a handle, rigidly fixed at the right angle to each other, with the working part representing a cylindrical rod, which at the free end has a flattened section with through holes, located at an equal distance from each other, at an angle to the longitudinal axis of the working part, the flattened section of the working part is smoothly curved at an obtuse angle; a limiter on a cannulated drill, representing hollow cylinders of the different height with an internal diameter, corresponding to the drill diameter. A step-by-step formation of the tibial bone tunnel is realised. The operated extremity is bent in the knee joint at the right angle. Beginning of the tibial tunnel is determined more laterally and lower than the tibial tuberosity and formed at an angle of not less than 55° to the articulate surface of the tibia. The guide-pin is passed with the sharp trihedral sharpening forward, then removed and introduced with the other end forward. After that, the device for the protection of the popliteal artery is introduced through the posterior-medial access, and the guide-pin is wedged in the closest to it hole of the flattened section of its working part. Limiters are successively put on the drill, with the number of limiters being selected in such a way that the part of the drill, free from the limiters, corresponds to the tibial tunnel length. The cannulated drill is passed along the guide-pin, fixed in the device for the protection of the popliteal artery, and the tibial tunnel is formed.

EFFECT: group of inventions makes it possible to reduce a risk of injuring the popliteal artery, reduce a risk of purulent-inflammatory complications.
