Specific embodiment
This acetabular outer cup implantable marker instrument is made up of acetabular bone Marking ring and mark handle, during described acetabular bone Marking ring is
Empty becket, its are internal for ink storage device, use ink holder in the present embodiment, ink storage device with for drawing mark
Nib is connected, and the present embodiment uses sponge nib, and quantity is eight, and written particular number is carried out also dependent on being actually needed
Adjustment, mark nib are extended to outside becket by the hole of becket, have the hole with female thread structure to be used on becket
Threaded connection connecting tube.The minimum 38mm of the internal diameter of acetabular bone Marking ring, is 78mm to the maximum, covers all at present acetabular bones for using
Cup size, can according to art used in the size of reamer for hip arthroplasty,acetabulum carry out the selection of different model, with the reamer for hip arthroplasty,acetabulum used in art
Outer radial mates, and the external diameter of reamer for hip arthroplasty,acetabulum is slightly less than or the internal diameter equal to acetabular bone Marking ring.Described mark handle includes handle, pushes away
Pulling plug, ink storage pipe.Push-and-pull bolt near-end is to project to the push-and-pull block on handle, and middle is pull bar, and distal end is piston, and push-and-pull bolt is remote
The piston at end is located in ink storage pipe, is equipped with external screw thread on the two ends of connecting tube, the company of ink storage pipe and connecting tube on handle body
Connect at hole, and ink storage device is equipped with the interior spiral shell matched with connecting tube with the connection hole of connecting tube on acetabular bone Marking ring
Line, connecting tube are threadedly coupled respectively at handle body and acetabular bone Marking ring, and convenient dismounting cleaning and assembling are used.
In operation after the suitable size of reamer for hip arthroplasty,acetabulum burr and depth, with the distal end connection syringe needle suction mark of connecting tube
Note methylene blue etc. sterilizes coloring agent as ink, removes syringe needle again, or also directly can be inhaled using connecting tube after being filled
Cancel malicious coloring agent, then the acetabular bone Marking ring that mark handle is matched with reamer for hip arthroplasty,acetabulum is connected, then the hand-held mark of operator
Acetabular bone Marking ring is positioned over reamer for hip arthroplasty,acetabulum outer rim by handle, promotes push-and-pull bolt to push the methylene blue in ink storage pipe in acetabular bone Marking ring,
So that the ink holder in acetabular bone Marking ring is fully moistened by methylene blue with eight mark sponge nibs, acetabular bone Marking ring is rotated, is made
Tissue of the mark sponge nib at patient's acetabular bone edge makes circular line markings.Finally by acetabular outer cup prosthese by circular mark
Note lines are implanted in the acetabular bone of burr, it is ensured that acetabular outer cup is implanted into the concentric circles of reamer for hip arthroplasty,acetabulum angle.
The specific embodiment of the present invention is not limited to embodiment with the form described by accompanying drawing, and those skilled in the art exists
