An endoscopic shank instrument has a tool carrier which is arranged at a distal shank end, is bendable relative to the shank and carries a tool. The tool includes at least one electrode which is conductively connectable to a voltage source via an electrical lead led through the shank. The lead is formed by a flexible circuit board in the region of the tool carrier and of the bending of the tool carrier.

A device for picture-providing diagnosis of tissue is selectively operated in a picture-providing white light diagnosis mode and a picture providing auto-fluorescence mode. A color camera having red, green, and blue sensors provides a monitor which picture signals. A light source emits fluorescence excitation light and additionally emits so much red light that the red light remitted by the tissue dominates the red fluorescence light in the picture providing auto-fluorescence mode. The signal from the red sensor of the camera is damped so that normal time appears green and pre-malignant and early malignant tissue appears red.

The interface circuit serves for connecting two apparatus by way of a bidirectional bus which comprises a data lead for transmitting data and a cycle lead for transmitting a cycle signal. The interface circuit consists of a circuit arrangement provided at each apparatus, which comprises a separating means for separating the data signal on the data lead and the cylce signal on the cycle lead in each case into a transmitting and a receiving branch, and which furthermore comprises in each case for the data lead and the cylce lead a bus driver having a differential transmitter and receiver. The data signals and cylce signals between the apparatus are transmitted via differential leads.
