Abstract

Изобретение относитс  к медицинской технике и может быть использовано в травматологии и ортопедии. Цель изобретени  - уменьшение травмировани  м гких тканей, повышение надежности фиксации стержн  и уменьшение времени на установку стержн  в костном отломке. Стержень содержит самонарезающую часть 1, котора  выполнена укороченной и снабжена гладкой концевой частью 5 с притупленным торцом. Нарезка самонарезающей части 1 выполнена с конусной проточкой 6 и на ней выполнены продольные наружные пазы 7, образующие при перечислении выступов нарезки режущие грани 8, которые формируют в кости спиральную канавку. Это позвол ет уменьшить врем  на установку стержн  в костном отломке. 3 ил.The invention relates to medical technology and can be used in traumatology and orthopedics. The purpose of the invention is to reduce the trauma of soft tissues, increase the reliability of the fixation of the rod and reduce the time for the installation of the rod in the bone fragment. The core contains a self-cutting part 1, which is made shortened and provided with a smooth end part 5 with a blunt end. The cutting of the self-cutting part 1 is made with a tapered groove 6, and longitudinal external grooves 7 are made on it, forming cutting edges 8, which form a spiral groove in the bone. This reduces the time required to install the rod in the bone fragment. 3 il.
