Surgical device with light

Abstract

An electrocautery unit for connecting to a handle of an electrocautery device, the unit comprises a body, a light unit and an electrode. The body has a body proximal end and a body distal end, and a body axis extending lengthwise along the center of the body. The body’s proximal end comprises a connecting element for connecting said body to a handle having a handle axis extending lengthwise along the center of the handle, so that said body axis is coaxial with said handle axis when said body is connected to said handle. The light unit may be constructed and arranged to emit a light having a central axis coaxial with said body axis. The electrode comprises a proximate end connected to the body distal end, and an electrode tip at a distal said. When the electrode is connected to the body, the electrode lays outside of the body axis and extends into said body axis such that the electrode tip is within said body axis, wherein said light and said electrode tip are coaxial to said body axis and said handle axis.
