Abstract: A device having an optical element with a conductive coating. The device may include an optical element, a conductive material and at least one connector. The conductive material is disposed on at least a portion of the optical element. The optical element, for example, may be an object lens of an endoscope or an optical coupler. The connectors (acting as terminal(s)) are capable of providing energy (such as electrical energy) to the conductive material. In one aspect, the conductive material is an optically transparent material. Advantageously, the device may allow visualization of an object—such as body tissue or other matter—concurrent with the application of energy to the object via the conductive coating. This allows the user to observe the alteration of tissue and other matter in real time as the energy is delivered.

Abstract: Provided are an endoscopic surgical device and a guide device that can satisfy the function of interlocking two medical instruments with each other. An overtube, which is punctured into a body wall and guides an endoscope and a treatment tool into a body cavity, includes an interlocking member that interlocks the forward and backward movements of the endoscope and the treatment tool with each other.
