Background

In the surgical treatment of orthopedic related diseases of children, in particular to the treatment of fracture of children, an intraosseous fixation metal bone needle, which is usually a smooth internal fixation needle, is often used, and one end of the needle is a sharp head, and the other end of the needle is a tail end (or another sharp head). In the treatment and use process, the needle is inserted from one end of the fracture in an electric drill or knocking mode and is fixed to the other end of the fracture through the fracture line, so that the alignment relation of the fracture end is stabilized, and the purpose of treating the fracture is achieved.

In the process of intra-osseous fixation and spicule treatment, one spicule alone cannot achieve sufficient and stable treatment, and two to three spicules are usually used in the treatment process to achieve effective treatment. After the first bone needle is driven in, when the second bone needle is driven in, the tail end of the first bone needle can block the needle inserting of the second bone needle, the needle inserting point and the needle inserting direction of the second bone needle are influenced, and the needle inserting difficulty is caused by the influence of the tail ends of the first two bone needles when the third bone needle is driven in.

The traditional bone internal fixation needle is called a Kirschner wire, and the Kirschner wire needs to be installed in the center of the front end of an electric drill in the using process and is locked by a key to be drilled into the electric drill for use. The operation of locking the drill bit by using the electric drill key is very complicated, and a great deal of time is wasted in the operation. The kirschner wire can not be correctly placed in the center of the drill bit often, the drill bit needs to be unlocked by using the key again, the placement position of the kirschner wire needs to be adjusted, the drill bit needs to be locked again, whether the kirschner wire is located in the center of the drill bit needs to be checked, and the fact that the kirschner wire can be normally used behind the center of the drill bit is confirmed after the operation.

Therefore, there is a need for a medical endosseous fixation needle that is convenient to use to solve the above problems.
