Technical Field
The utility model relates to the technical field of humerus, in particular to a humerus intramedullary nail with high stability.
Background
The humerus is a non-load long bone, the internal fixation is selected without emphasizing the strong internal fixation, the intramedullary nail is used for fixing the fracture and not fixing the bone firmly, the local micro-motion and the pressurization exist in the fracture area, the blood supply of the fracture area is kept as much as possible, the blood supply of fracture blocks is ensured, and the micro-motion can generate favorable strain among the fracture blocks, so that the growth healing of the bone is promoted.
Because the intramedullary nail adopts non-firm internal fixation, the existing micro-motion between fracture areas easily causes the displacement of fracture ends, thereby causing fracture disconnection. In the prior art, the stability of the fixation of the intramedullary nail is improved by arranging the locking screw, because the locking screw needs to be fixed on the intramedullary nail, the installation space and the installation mode are limited, and for various complex fractures, such as spiral complex fractures, multi-section complex fractures and irregular complex fractures, the prior intramedullary nail can not provide stable and good position maintenance after resetting due to limited fixation positions, and the diversity and the stability of the fixation of the intramedullary nail still need to be improved.
Disclosure of Invention
The utility model aims to provide a high-stability intramedullary nail for humerus, which solves the problems that the intramedullary nail in the prior art cannot provide stable and good position maintenance after resetting, and the diversity and stability of the fixation of the intramedullary nail are still to be improved.
In order to achieve the above purpose, the present utility model adopts the following technical scheme:
the utility model provides a high-stability humerus intramedullary nail, includes proximal end nail section and distal end nail section, proximal end nail section and distal end nail section can dismantle the connection, one side of proximal end nail section is provided with a plurality of interlocking screw and locking screw, one side of distal end nail section is provided with a plurality of locking screw.
Preferably, a pressurizing hole is formed in one side of the proximal nail section, and a pressurizing screw is connected to the inside of the pressurizing hole.
Preferably, a positioning groove is formed in the end portion of the proximal nail section.
Preferably, the bottom end of the proximal nail section is connected with a connecting screw rod through a first gasket, and the top end of the distal nail section is provided with a connecting screw hole.
Preferably, the top end of the distal nail section is connected with a second gasket, and the top of the second gasket is connected with a plurality of rubber bulges.
Preferably, the bottom of the first gasket is connected with a first bulge matched with the rubber bulge.
The utility model has at least the following beneficial effects:
through the setting of near-end nail section and distal end nail section, the cooperation of interlocking screw and locking screw forms crisscross second grade interlocking structure, can follow a plurality of positions with intramedullary nail owner nail and fracture piece fixed together, has improved the fixed stability and the variety of brachial intramedullary nail, is favorable to the position maintenance after the complex fracture resets, and simple structure is reliable, suitable popularization.
