Surgical device with light

An electrocautery unit for connecting to a handle of an electrocautery device, the electrocautery unit comprising:

• a light element constructed and arranged to emit a light having a light central axis;
• a connecting element constructed and arranged to connect to a handle of an electrocautery device;
• a shaft between said light element and said connecting element, said shaft being coaxial with said light element;
• and
• an electrode, wherein said electrode extends distally from said body from outside the light central axis toward the light central axis, said electrode having an electrode tip which terminates at said light central axis.

An electrocautery unit for connecting to a handle of an electrocautery device, the electrocautery unit comprising:

• a body having a proximal end and a distal end, wherein said proximal end comprises a connecting element constructed and arranged to connect to a handle of an electrocautery device;
• a light element disposed at said distal end, said light element constructed and arranged to emit a light having a light central axis;
• and
• an electrode, wherein said electrode extends distally from said body from outside the body axis toward the body axis, said electrode having an electrode tip which terminates at said light central axis.

An unit for connecting an electrode to a handle of an electrocautery device, the electrocautery unit comprising:

• a body having a proximal end and a distal end, and a body axis extending between said proximal end and said distal end,
• wherein said proximal end comprises a first connecting element for connecting said body to a handle of an electrocautery device, and
• said distal end comprises an arm having a second connecting element for connecting said body to an electrode, said arm extending from said distal end from outside the body axis toward said body axis;
• and
• a light element disposed at said distal end, constructed and arranged to emit a light having a light central axis coaxial with said body axis.

A retrofit electrocautery kit compatible with an existing surgical instrument handle, said electrocautery kit comprising:

• an electrocautery unit having
• a body having a proximal end and a distal end, and a body axis extending between said proximal end and said distal end, wherein said proximal end comprises a connecting element constructed and arranged to detachably connect to a handle of an existing surgical instrument handle, and
• a light element disposed at said distal end, constructed and arranged to emit a light having a light central axis coaxial with said body axis,
• wherein said distal end comprises an arm extending distally from outside the body axis toward said light central axis, said arm having an arm tip having a second connecting element;
• and
• an electrode having a third connecting element for engaging said second connecting element to connect said electrode to said arm at said arm tip, wherein said electrode includes an electrode tip extending toward and terminating at said light central axis when said electrode is attached to said arm.
