First, the first handle 800 of the needle unit 120 is connected to the second handle 900 of the stylet unit 140, and the second handle 900 of the stylet unit 140 is connected to the main handle 700. ) To assemble the needle unit 120, the stylet unit 140 and the main handle 700 in the configuration of the puncture needle (100).

And, as shown in Figure 14, the operator grasps the main handle 700 and inserts the puncture needle 100 into the body of the patient. And, as shown in Figure 15, when the puncture needle 100 is inserted adjacent to the bone, the first handle 800 of the needle unit 120 and the second handle 900 of the stylet unit 140 The stylet unit 140 is removed and the guide pin 400 is inserted through the hole 820 of the first handle 800 of the needle unit 120.

Then, the needle unit 120 is removed while the guide pin 400 is inserted.

The main handle 700 is separated from the second handle 900 of the stylet unit 140 and then assembled with the second handle 900 of the decelerator 300. Then, when the first handle 800 of the cannula 200 is connected to the second handle 900 of the decelerator 300, the assembly of the cannula 200, the decelerator 300, and the main handle 700 is provided. Is completed.

As shown in FIG. 16, the assembly of the cannula 200, the decelerator 300, and the main handle 700 is inserted into a hole in the body by the guide pin 400. Accordingly, the hole drilled by the puncture needle 100 is expanded.

Then, the guide pin 400 is removed, and the first handle 800 of the cannula 200 and the second handle 900 of the diller 300 are removed to remove the diller 300. Only cannula 200 is located. Then, when the main handle 700 is separated from the second handle 900 of the decelerator 300 and assembled with the second handle 900 of the drill 500, the drill 500 and the main handle 700 of the The assembly is complete.

As shown in FIG. 17, the assembly of the drill 500 and the main handle 700 is inserted into the body through the tube 210 of the cannula 200, and the rod 510 of the drill 500 is inserted. Rotate under pressure to puncture the hole into the bone. At this time, since the hole is formed inside the bone by the rotation of the drill blade 512, it is possible to prevent the fracture of the bone as compared to the method of drilling the hole while applying a physical impact on the bone.

When the drilling of the hole into the bone is complete, the drill 500 is removed. The main handle 700 is separated from the second handle 900 of the drill 500 and then assembled with the second handle 900 of the injection unit 620. Accordingly, the assembly of the injection unit 620 and the main handle 900 is completed, and is inserted into the bone through the tube 210 of the cannula 200.

And, as shown in Figure 18, after supplying the bone cement in the injection pipe 621 of the injection unit 620, push the pusher rod 641 of the pusher 640 into the injection pipe 621. Inject bone cement into the bone marrow cavity. At this time, since the bone cement is injected into the bone marrow cavity by the movement in the main inlet pipe 621 of the pusher rod 641, it prevents bone deformation more effectively than when using a syringe or a gun to inject bone cement. can do.

Meanwhile, a balloon catheter is inserted into the bone marrow cavity through the tube 210 of the cannula 200 before the bone cement is injected after the hole in the bone is formed, and the balloon is expanded inside the bone marrow cavity. This may be followed by a process of expanding the part of the medulla in the bone marrow.

After the bone cement is injected into the bone marrow cavity, the process of injecting the bone cement into the bone marrow cavity of the bone marrow cavity is completed by removing the cannula 200 and the distributor 600 and sealing the perforated portion. .
