Problems solved by technology

[0003] However, during the implantation process, the tantalum rods need to withstand a large force, and some tantalum rods will be twisted or broken when the bone is finally filled.
At the same time, it takes a lot of force to firmly fix the tantalum rod inside the bone, but in terms of current medical methods, steel plates are generally used to cover it, and this method is actually not the best choice.

Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0025] Such as Figure 1 to Figure 13 As shown, a porous tantalum tantalum rod device includes a tantalum rod 1-1, which is characterized in that: the tantalum rod device includes a protection tube 1-2 for accommodating the tantalum rod, and the side wall of the protection tube is provided with a concave Pit 1-3, conical protrusion 1-4 is provided in the pit, the top of the conical protrusion is flat with the outer surface of the inner wall, and the protective tube is made of rigid elastic material.

[0026] When in use, put the protection tube into the drill hole first, and then insert the tantalum rod into the protection tube. The protection tube is firmly fixed in the borehole by pressing against the inner wall of the borehole. In this way, the protection tube can protect the tantalum rod from being squeezed, and at the same time, it has b...

Abstract

The invention discloses a multi-hole tantalum rod device which comprises a tantalum rod. The device is characterized by comprising a protective tube for containing the tantalum rod, a concave pit is arranged in the side wall of the protective tube, a conical protrusion is arranged inside the concave pit, the top end of the conical protrusion is flush with the outer surface of the inner wall, and the protective tube is made of rigid elastic materials. A protective frame wraps the tantalum rod, due to the design, it is ensured that the tantalum rod is not broken when embedded into a pre-embeddedhole, and the integrity of the tantalum rod is ensured.

Description

technical field [0001] The present invention relates to a surgical instrument. Background technique [0002] The human hip joint is a very important part. When the hip joint suffers from disease, such as joint necrosis, it is necessary to remove the necrotic tissue and fill some artificial materials into the hip joint. Most of the filling materials currently used are porous tantalum materials. During the operation, an electric drill is used to drill a hole in the hip joint, and then the necrotic joint tissue in the hole is removed, and then a tantalum rod is filled into the hole, and finally the gap is filled with healthy bone fragments and the wound is sutured. [0003] However, during the implantation process, the tantalum rods need to withstand a large force, and some tantalum rods will be twisted or broken when the bone is finally filled. At the same time, it takes a lot of force to firmly fix the tantalum rod inside the bone, but in terms of current medical methods, s...
