A video endoscope with lateral viewing direction including a shaft having proximal and distal ends, an objective lens in the distal end, an image sensor, and a main body at the proximal end. Where a first grip rotationally fixed relative to the shaft and the main body to rotate the shaft and the main body to change the viewing direction of the objective lens. A second grip is disposed on the main body to be rotatable relative to the shaft and the main body to maintain a horizontal position of the image sensor when the viewing direction is changed. An annular seal is disposed between the second grip and the main body and/or the first grip. The seal includes a circumferentially wound coil spring having windings oriented such that a surface vector of a surface spanned by a single winding points substantially in a circumferential direction of the seal.
