Spinal massager

A spinal massager comprising:

• a lower structure;
• a saddle mounted at an upper portion of the lower structure to bear the user's back at an upper surface thereof, a length-adjustment vertical bar connected to the saddle to support the saddle;
• and a feet holder located at an end of the length-adjustment vertical bar to catch the user's feet, further comprising:
• a transfer drive unit to transfer a hitting head, mounted inside the saddle, along the vertebrae;
• a hitting drive unit mounted inside the saddle to be transferred by the transfer drive unit and adapted to drive the hitting head to hit the vertebrae;
• a key operating panel mounted on a side of the saddle to generate various key signals to induce hitting and transfer operations;
• a memory to store preset signals from key buttons of the key operating panel and motor drive data depending on the preset signals from the key buttons;
• and
• a controller to generate control signals to drive both the transfer drive unit and the hitting drive unit upon receiving the preset signals from the key buttons of the key operating panel, thereby allowing the hitting head to hit the vertebrae while being transferred along the vertebrae within the saddle under control of the controller,
• whereby the spinal massager massages the vertebrae of a user, who lies thereon with the feet elevated above the head, with a predetermined constant strength, thereby allowing a herniated spinal disc to be readily restored into a gap produced between the vertebrae.
