Abstract
A medical duplex titanium nail comprises two titanium nail bodies connected side by side. The ends of first clamping arms or/and second clamping arms of the two titanium nail bodies are provided with a connecting rod or connecting rods, namely, the connecting rod is fixed to the first or second clamping arms of the two titanium nail bodies to form a single-connecting-rod duplex titanium nail, or the connecting rods are fixed to the first and second clamping arms of the two titanium nail bodies to form a double-connecting-rod duplex titanium nail. The hinging portion of the first clamping arm and the second clamping arm of each titanium nail body is a papillary arc. The bent duplex titanium nail is more stable in structure and not prone to deformation; the locking function of a vertical-plane nail body closing opening is achieved, and therefore a blood vessel will not slip off in the direction parallel to the nail body closing direction; due to connecting rod connection between the double nail bodies and wrinkles formed by extrusion of the blood vessel, slip-off of the parallel surface of the section of the blood vessel is quite difficult.
