Tantalum rod, the bottom of the tantalum rod has spikes, the spikes are evenly distributed at the bottom of the tantalum rod, the length direction of the spikes is provided with a continuous arrangement of concave points, the length of the spikes is 0.2 to 0.5cm. The tantalum rod also comprises a protection tube accommodating the tantalum rod, the two ends of the protection tube are open, the inner cavity is hollow, wherein the protection tube is one third of the length of the tantalum rod. The tantalum rod is provided with spikes at the bottom end of the tantalum rod. When the tantalum rod is placed, the spikes will penetrate into the bottom end of the drill hole, and there are concave points on the spikes to facilitate the bone marrow cells to spread to the tantalum rod along the spikes, thus improving the success rate of tantalum rod treatment. At the same time, a protective frame is wrapped around the tantalum rod to ensure that the tantalum rod will not be broken when implanted into the pre-buried hole. Guarantee the integrity of the tantalum rod.
The femoral joint is a very important part of the human body. When the hip joint is diseased, such as joint necrosis, it is necessary to remove the dead tissue and fill some artificial materials into the femoral joint. At present, the filling materials used are mostly porous tantalum materials. During the operation, the femoral joint is drilled with an electric drill, the necrotic joint tissue is removed from the hole, tantalum rods are filled into the hole, and healthy bone tissue is used to fill the gap and close the wound.
In the process of using tantalum rods for treatment, the size of the drill hole is required to be consistent with the size of the tantalum rods. In actual surgery, the hole aperture and depth of the drill hole are larger than that of the tantalum rods. As a result, the bottom end of the tantalum rods cannot contact the bottom of the drill hole, and after the tantalum rods are implanted, bone induction cannot be performed, resulting in treatment failure.
