| can touch the simulated ribs.

| needle tip punctured the epidermis with a real sense of resistance and needle penetration.

| can simulate complications during the operation, and can be used for ultrasound-guided puncture with real ultrasound equipment.

| is worn on real people to facilitate the determination of puncture position and face-to-face communication with real people.
