Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0028] Such as Figure 1 to Figure 14 As shown, a tantalum rod device for surgery includes a tantalum rod 1-1, the tantalum rod device includes a protection tube 1-3, and the wall of the protection tube is provided with a left helical opening 1-4. The starting point is located at the head end of the protection tube, and the wall at the bottom of the tube body is provided with sharp protrusions 1-5, and the direction of the protrusions is set along the length direction of the protection tube. The outer peripheral wall of the tantalum rod is provided with protrusions 1-2 consistent with the groove, and the width of the opening is 3 mm. When installing, first rotate the tantalum rod into the protection tube, at this time, the protrusion on the tantalum rod matches the opening on the protection tube, the tantalum rod is firmly fixed in the protect...

Abstract

The invention discloses a tantalum rod device for surgery. The tantalum rod device comprises a protection tube, wherein sharp bulges are arranged on the wall of the bottom of a tube body, and the direction of the bulge is along the length direction of the protection tube. A spiral opening is arranged in the wall of the protection tube, the starting point of the opening is positioned on the head end of the protection tube, and bulges consistent with grooves are arranged on the outer circumferential wall of a tantalum rod. The bulges on the tantalum rod and the tantalum rod are integrally manufactured, and the tail end of the opening is positioned in the center of the protection tube. For the tantalum rod device for surgery, a layer of protection rack wraps the outer part of the tantalum rod, with the design, no breaking occurs when the tantalum rod is implanted in a pre-embedded 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 object of the present invention is to provide a tantalum rod device for operation, which ca...
