A lateral light-emitting device for connecting a medullary guide wire is disclosed. The device comprises a closed main body, a front-end protecting unit for protecting the front end of the main body, and a connecting unit disposed at the distal end of the main body. The inside of the main body is further arranged with a lighting unit, a power supply unit, a light-scattering unit, a light intensity modulating unit, if necessary, and at least one transparent window. The device is able to fit to different types of medullary guide wires. The power supply unit provides power to the lighting unit to produce light emitted to the light-scattering unit and being diverted laterally through the transparent window of the main body after suitably modulating the light intensity. Thereby, the device is illuminated from within the bone cavity to allow observing the operating screw hole location from outside of the body and to enable precisely nailing while proceeding with the intra-medullary nailing procedure.

A pocket calculator includes a casing having on its front face numeric and function keys and a numeric first liquid crystal display (LCD) and a message second LCD. Housed in the casing is a calculator network module housing and a first battery connected through a key operated switch contained in the network to energize the network and actuate the first LCD. An inverter IC integrated circuit and second battery are housed in the casing and actuate the second LCD, the battery being connected to the inverter input through a transistor switch rendered conductive in response to the energization of the calculator network. Alternatively, a message third LCD provided in which the message is devisualized upon the application of a voltage thereto with the energization of the computer. The second and third LCDs may be a single common unit with the faces of a section of a common LCD being coated with light polarizing layers which are optically mutually perpendicular.
