Tibial/humeral intramedullary nail and tibial group and humeral group using tibial/humeral intramedullary nail

Abstract

The invention discloses a tibial/humeral intramedullary nail and a tibial group and a humeral group using the tibial/humeral intramedullary nail. The tibial/humeral intramedullary nail comprises a main nail, a core nail and a cock. The main nail comprises a main nail tail and a hollowed cavity. The hollowed cavity comprises a large-diameter cavity which is arranged in a main nail head. The main nail tail comprises at least one split groove. A core nail head is accommodated within the large-diameter cavity and the core nail head is greater than a small-diameter cavity in diameter. An outer screw thread is arranged at the tail of a core nail body. The cock comprises an inner screw thread. The contour line of a cross section of the cock, along an axial direction of the main nail, is represented as an isosceles triangle. The inner and outer screw threads are coupled, so that the cock is arranged at the tail of the core nail body. The tibial/humeral intramedullary nail, which is provided with the core nail and the cock, has a self-locking function, so that a fixed screw is prevented, and subsequently, operations are simplified and facilitated and using cost is reduced.

AI Technical Summary

Benefits of technology

This invention relates to an improved orthopedic implant called this type of nails or pins used for fixing fractured parts together. These nails have a special design made by combining two materials: one material forms part of the main body of these tools (the cortex) and another material on top. When they are fixed into place, there will also hold them securely enough to prevent movement when subjected to stress such as weight bearing. By doing things like making sure each component fits properly without requiring any other devices attached, the risk of surgery can decrease due to reduced costs associated with installing conventional methods. Additionally, if the components become loose after being installed, less invasive procedures may still work well even more safely than those performed through openings at their ends. Overall, this new tool provides technical benefits over existing techniques but requires no extra equipment compared to current options.

Problems solved by technology

This patented technical problem addressed by the present inventor relates to an improved type of device used for treating fractures caused by osteoporotic compression syndrome (OCS). Current methods involve inserting stainless steel pins into holes drilled directly across the damaged portion of the spine with multiple steps involving drilling and countersinking each hole separately before attaching new anchors. These techniques have drawbacks such as difficulty ensuring accurate placement due to weaknesses like muscle fibers surrounding the joint being treated, potential injury from sharp instruments during insertion, lack of precision control over how well these procedures work, and potentially harmful side effects associated with prolonged use of metal tools.
