Abstract
The utility model discloses a multifunction six-prismatic intramedullary nail which comprises an upper part and a lower part, wherein, the end head of the upper part is provided with a connecting hole, and the lower part is provided with an interlocking hole. The cross section of the nail is solid to form a hexagonal shape. The intensity is high, the torsional property resistance is good, the requirements that a bone fracture is fixed, and a bone is cured can be satisfied, and the utility model has the good effect on preventing rotation in a marrow and the bone. Although the utility model has the good fixed effect, the whole medullary cavity can not be thoroughly occupied, the utility model only acts on six points at the surface of a medullary membrane, and blood circulation in the marrow can not be influenced too much. The utility model can be suitable for requirements of different fracture sites, and the application is wide. An interlocking internal fixation can be completed, an effect on preventing rotation can be strengthened, an effect on preventing abbreviation can be obtained, the interlocking fixation can be completed with a simple locator, and the utility model can be used for treating a fracture of limbs.
Description
This utility model relates to the intramedullary needle that is specifically designed to extremity fracture in a kind of hospital.
Present intramedullary needle has round pin, V-arrangement pin.The cross section of round pin is rounded, the intensity height, but rotation is moved easily; The cross section of V-arrangement pin is in the shape of the letter V, and is not easy rotation, but insufficient strength, anti-bending strength is poor.More than two kinds of intramedullary needles also lack the interlocking function, can not solve the problem of key rotation and shortened deformity.
The purpose of this utility model is that pin in a kind of multi-functional six-prismatic will be provided, and its intensity height, is not easy rotation and moves, can prevent key rotation and shortened deformity.
The purpose of this utility model is achieved in that this intramedullary needle is divided into the upper and lower, and there is connecting hole the termination on top, and the interlocking hole is arranged at the bottom, and the cross section of pin is solid six prismatics.
The cross section of described pin can also be hollow six prismatics.
The cross section of described pin can also be open hollow six prismatics.
Intensity height of the present utility model, antitorque commentaries on classics performance is good, can reach the requirement of fixing fracture up to knitting, reaches the anti-rotation effect of tool in the skeleton in bone marrow.Though good fixed effect is arranged, do not take whole pulp cavity, only act on six points on perimyelis surface, little to bone marrow inner blood circulating effect.Can adapt to the needs of different fracture sites, purposes is wide.Can finish the interlocking internal fixation, more can strengthen it and prevent revolving effect, also can reach anti-cripetura effect, available easy localizer is finished interlocking and is fixed.Can be used for treating extremity fracture.
