Electrical-stimulation device and operation method thereof and electrical-stimulation system

An electrical-stimulation system, comprising:

• at least one lead;
• and
• an electrical-stimulation device, electrically connected to the at least one lead, wherein the electrical-stimulation device comprises:
• an electrical-stimulation signal-generating circuit, having a first channel for providing a first electrical-stimulation signal;
• a first connection unit, having a plurality of first contact points and a plurality of second contact points, wherein the first contact points and the second contact points are alternately arranged;
• a first conductive member, connected to the first contact points;
• and
• a second conductive member, connected to the second contact points;
• wherein the first conductive member and the second conductive member are electrically connected to the first channel, so that the first electrical-stimulation signal is transmitted through the first contact points and the second contact points corresponding to the first channel.

An operation method of an electrical-stimulation device, comprising:

• providing a first electrical-stimulation signal via a first channel of an electrical-stimulation signal-generating circuit;
• providing a first connection unit, wherein the first connection unit has a plurality of first contact points and a plurality of second contact points, and the first contact points and the second contact points are alternately arranged;
• using a first conductive member to connect to the first contact points;
• using a second conductive member to connect to the second contact points;
• electrically connecting the first conductive member and the second conductive member to the first channel;
• and
• transmitting the first electrical-stimulation signal through the first contact points and the second contact points corresponding to the first channel.
