Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] Such as Figure 1 to Figure 13 As shown, a tantalum rod device with a protective tube includes a tantalum rod 1-1, the device includes a protective tube 1-2 for accommodating the tantalum rod, the two ends of the protective tube are open, and the inner cavity is hollow, wherein the upper end of the tantalum rod and the lower end respectively have an inclined surface 1-3, and the two inclined surfaces fit together to form a complete circumference of the tantalum rod.

[0025] When using, first use a drill to drill a hole, then take out the bad bone, put the protection tube into the drill hole, cut off the inclined surface of one end of the tantalum rod, press the tantalum rod into the protection tube, if the length of the tantalum rod is not enough, you can Cut off a new tantalum rod with only the inclined surface at the lower end, put t...

Abstract

The invention discloses a tantalum rod device with a protection tube. The tantalum rod device comprises a tantalum rod, and is characterized in that the device comprises a protection tube for accommodating the tantalum rod, wherein two ends of the protection tube are open, an inner cavity is hollow, each of the upper end and the lower end of the tantalum rod is provided with an inclined face, andthe two inclined faces attach together to form the complete tantalum rod periphery. For the tantalum rod device with the protection tube, one layer of protection frame wraps the outer part of the tantalum rod, due to the design, the tantalum rod can not be broken when implanted into a pre-embedding hole, and thus the completeness of the tantalum rod is guaranteed.

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. Contents of the invention [0004] The purpose of the present invention is to provide a tantalum rod device with a protective tube...
