Pressurizing bone needle

Abstract

The invention discloses a pressurizing bone needle and relates to the field of medical apparatus and instruments. The pressurizing bone needle comprises a cylindrical needle body, both ends of the needle body are provided with tips including a first tip and a second tip, and the middle of the needle body is provided with a through hole; the part of the through hole of the needle body, which is close to the first tip, is provided with a casing ring, and the part of the needle body, which is close to the second tip, is provided with first equal-interval threads at equal intervals; the needle body is provided with second equal-interval threads which are connected with the first equal-interval threads, and the interval of the first equal-interval threads is greater than that of the second equal-interval threads. According to the pressurizing bone needle, after being positioned, the needle body can bind and strengthen a bone through the through hole to achieve effective fracture reduction and stable fixation; both the first tip and the second tip are usable, the second tip with the threads can serve as the pressurizing bone needle, and the first tip can serve as a guide needle, so thatthe pressurizing bone needle is very convenient to use and greatly reduces the processing difficulty.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a pressurized bone needle. Background technique [0002] In recent years, with the development of the transportation industry and the construction industry, the annual incidence of fractures is on the rise, and surgery is currently the most effective treatment method. The purpose of surgery is to restore the normal sequence and curvature of the fracture , height and activity, maintain the original stability, and improve the function of compressed nerves. With the improvement of various new surgical theories and fixation techniques, clinical surgical methods have also been continuously improved. Internal fixation with bone pins is the most effective treatment for fractures. [0003] Medical pressurized bone pins are usually used in orthopedic internal fixation operations. By using the principle of pressurization, the fractured bone fragments are directly fixed, and the broken e...

Problems solved by technology

However, the existing bone needle itself is relatively small, and the gradual thread is set on its surface, which is difficult to process and high in cost, which increases medical costs to a certain extent.
