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

[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0026] Such as Figure 1 to Figure 13 As shown, a porous tantalum rod system includes a tantalum rod 1-1, and the system includes a protection tube 1-2 for accommodating the tantalum rod, wherein the periphery of the protection tube is provided with a spiral protrusion 1-3 , one end of the protection tube is also provided with a socket 1-4, and the tantalum rod is fixed on the protective sleeve through the insertion strip through the tantalum rod in the socket.

[0027] The helix is ​​left-handed or right-handed.

[0028] The protection tube matches with the tantalum rod.

[0029] There is a blind hole on the tantalum rod, and the inserting strip is inserted into the blind hole.

[0030] The protection tube is made of titanium alloy material.

[0031] During the operation, put the tantalum rod into the protective tube first, then fix the ta...

Abstract

The invention discloses a multi-hole tantalum rod system which comprises a tantalum rod. The system is characterized by comprising a protective tube for containing the tantalum rod, a spiral protrusion is arranged around the protective tube, an insertion hole is formed in one end of the protective tube, and the tantalum rod is fixed to a protective cover by enabling an insertion strip to penetratethrough the tantalum rod in the insertion hole. 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-embedded hole,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...
