The tantalum rod device comprises a tantalum rod, which is characterized in that the tantalum rod device also comprises a protective tube for wrapping the tantalum rod, and the protective tube has uniformly distributed holes, the tantalum rod is made of porous tantalum, and the holes are circular or oval. The invention adopts a protective frame wrapped on the outside of the tantalum rod, and such design can ensure that the tantalum rod will not be broken when implanted in the embedded hole, and ensure 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.
The tantalum rod device comprises a tantalum rod 1-1, and the tantalum rod device also comprises a protective tube 1-2 for wrapping the tantalum rod, which has uniformly distributed holes on the protective tube. In this embodiment, the tantalum rod is made of porous tantalum. The holes are round and oval. The holes around the protective tube have 6 in a horizontal plane. The protective tube is made of titanium alloy. The placement of holes in the protective tube can reduce the metal material required for the protective tube without reducing the strength of the protective tube, and the presence of holes also facilitates the re-growth of the internal tissue of the bone.
In use, the protective tube is first placed in the groove on the base of the cleaning device, so that the two openings of the protective tube are connected with the inlet hole and the outlet on the side wall of the base, and then the cleaning belt is pulled out from the cleaning belt holding device and placed on the pallet. The linear motor is controlled by the single chip microcomputer to press down the telescopic rod, and the gravity ball at the bottom is squeezed into the mouth, and the falling mouth is deformed and expanded. As the gravity ball falls, the T-head of the cleaning belt is squeezed into the T-slot of the gravity ball, and then compressed air is injected into the hole to push the gravity ball to drive the cleaning belt to overcome the tension of the coil spring in the cleaning bag holding device and move along the protective tube body.
