ELASTIC INTRAMEDULLARY NAIL TIP Russian patent published in 2024 - IPC A61B17/72 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medical equipment and can be used for osteosynthesis of long bones of extremities, as well as in elongation of long bones of upper and lower extremities as a component reinforcing bone regenerate. Tip for the elastic intramedullary nail is a volumetric part comprising a longitudinal slot with a threaded portion made on the side of the distal end of the part with the possibility of being connected to the mating end of the intramedullary nail, and a through transverse hole made on the side of the proximal end of the part with the possibility of receiving a mating part of the working instrument for force action on the intramedullary rod for its immersion into the medullary canal or extraction from the bone at the end of treatment. Part is made atraumatic with maximum value of transverse dimension not exceeding 6 mm, in the central part it comprises a cylindrical section changing from the distal end into a section in the form of a truncated cone, from the proximal end - into a section having a rounded surface. Kit for intramedullary osteosynthesis includes an elastic intramedullary nail and said tip.

EFFECT: use of the group of inventions enables to provide reliable fixation of the intramedullary nail in the medullary canal with reduced risk of seroma formation, contractures, and also considerably facilitates rod extraction (removal) from small approaches at the end of treatment.
