Abstract
A highly compact focusable video camera for use in medical and surgical procedures in conjunction with an endoscope is shown. The focusable video camera includes a two-part body having a first body portion having an optically apertured forward end portion thereof and a cylindrical sidewall, a second body portion having a rearward end portion and a cylindrical sidewall wherein the first and second body portions are slidable one into the other and having portions of their respective cylindrical walls overlapping. A coacting member is located on the overlapped portion of the cylindrical wall of each body portion and causes relative forward and rearward axial motion of the body upon rotation of one body relative to the other. The body portions define a cavity having an optical aperture which defines an optical axis extending through the optical system and outside the body for receiving and transmitting optical images received from the endoscope. The optical system includes a forward portion mounted on the first body portion and a rearward portion located on the second body portion and a sensor-converter which receives and converts the optical image to an unprocessed video signal and a video electronic processing circuit in the cavity extending around the outside of the rearward portion of the optical system.
