EDG® Ortho 65mm is a single-use electronic depth gauge used to measure the depth of a cavity (i.e. bone screw hole) to enable surgeons to select the appropriate length of screw in orthopedic procedures. This device some sterile and ready-to-use once removed from its packaging. This DI is appropriate for plating systems that require a 4mm offset depth gauge
A surgical instrument designed to measure the depth of a recess, usually to measure the depth of holes being drilled in bone to determine the length of the bone screw to be used. It may take the form of: 1) a device with a moveable (sliding) centrepiece (a prong), the tip of which is inserted into the recess to read from a scale; 2) a circular disc with a central hole which is clipped to a drill bit so that the device slides up as the drill bit is advanced; or 3) a cylindrical rod with markings. This is a single-use device.
