Anti-rotation film nail system

Abstract

The invention discloses an anti-rotation film nail system. The anti-rotation film nail system comprises a main body and an inner groove, wherein a nail head is arranged at the upper end of the main body; an annular groove is formed in the middle part of the nail head; a nail body is fixed to the lower side of the nail head; through holes are formed in the left side and the right side of the upperend of the nail body; a screwdriver is arranged inside the inner groove; the inner groove is formed in the nail body; a thread is arranged on the surface of the screwdriver; an opening is formed in the outer side of the lower end of the thread; a rotating ring is mounted on the outer side of the opening; an internal thread is arranged on the inner wall of the middle part of the rotating ring; outer walls are fixed to the upper end and the lower end of the internal thread; grooves are formed in the outer walls; pointers are fixed to the inner parts of the grooves; a perforated hole is formed inthe middle part of the rotating ring. The anti-rotation film nail system comprises two through holes which are centrosymmetric relative to the nail body, and a rope can run through the through holes,so that the whole main body is convenient to mount and detach and the actual using performance thereof is improved.

Description

technical field [0001] The invention relates to the technical field of membrane nail devices, in particular to an anti-rotation membrane nail system. Background technique [0002] Chinese Journal of Stomatology, July 2003, Volume 38, Issue 4, Pages 248-250, published an article titled "A Preliminary Study on the Application Effect of Pure Titanium Membrane in Implant Surgery" The article discloses the use of pure titanium membrane to establish a space for bone regeneration and repair, and the method of fixing the titanium membrane with implants and covering nuts can prevent membrane displacement and collapse, and at the same time ensure the stability of transplanted bone fragments and blood clots , which is beneficial to bone repair, which involves the application of membrane nail system. [0003] The film nail system on the market has complex and difficult control of advance and retreat, which makes it difficult to move the film nail, making it extremely inconvenient to us...
