Abstract

The pin for osteosynthesis refers to traumatology and orthopedics and is designed to provide decompression of the bone marrow channel while preventing the destruction of the pin when inserted into the bone canal. The pin is made in the form of coaxial tubes 1-3, rigidly connected to each other, by longitudinal gluing the bioinert polymeric mass of 4 and 5 into the body by gluing them. The tubes 1-3 are made of cortical bone layer of a person or animals subjected to immunological treatment. Tubes 2, 3 and 1 are tightly inserted one into another, with the channel 6 of the inner tube free, the input end of tubes 1, 2 and 3 is pointed, and the fastening is made with a chamfer. 3 il.

The invention relates to medical technology, namely to traumatology and orthopedics.

The purpose of the invention is to provide a decompression of the medullary canal while preventing the destruction of the pin when inserted into the bone canal.

FIG. 1 schematically shows the proposed pin for osteosynthesis, a longitudinal section; in fig. 2 - the same set in the femur; in fig. 3 — U, section A-A in FIG. one.

The pin contains a rod made in the form of coaxial tubes 1-3, rigidly interconnected by gluing bioinert resorption, it is in the body with a polymer mass of 4 and 5. Tubes 1-3 are made of cortical layers of a person or animals subjected to immunological treatment. Tubes 1 - 3 tight

The pin is used as follows.

From the side of the greater trochanter a soft tissue incision is made. Then, the bone marrow canal is drilled to the required depth with the help of a mandrel 8 and the pin is hammered into the bone. The wound is sutured in layers. The pin for osteosynthesis can also be installed in any other large tubular bone.

Claims (1)

1. A pin for osteosynthesis, containing a core of absorbable material in the body, characterized in that, in order to decompress the bone-brain canal, the stem is made of coaxial tubes placed one into another, fastened into one another, and channel 6 In the inner tube 3 it should be free absorbed in the body polybode. The input end of the tubes 1-3 ost-dimensional mass. and the fixing end of the outer tube 12. The pin according to claim 1, characterized in that made with a chamfer 7 under the mandrel 8 dl in order to prevent the destruction of the pin preventing chipping during clogging when inserted into the bone channel, Lift.Shift made with chamfer. The pin is used as follows. From the side of the greater trochanter a soft tissue incision is made. Then, the bone marrow canal is drilled to the required depth with the help of a mandrel 8 and the pin is hammered into the bone. The wound is sutured in layers. The pin for osteosynthesis can also be installed in any other large tubular bone. Invention Formula 1. Pin for osteosynthesis, containing a core of absorbable material in the body, characterized in that, in order to decompress the bone medullary canal, the core is made of coaxial tubes placed together in another, fastened absorbable in the body 2 Compiled by L.
