1. An electrocautery device for dissecting biological tissue, the electrocautery device comprising:
an insulated electrode, the insulated electrode comprising:
an electrode having a distal tip configured to deliver an electrical current to a biological tissue and a proximal end configured to be coupled to an energy supply source; and
an insulation material radially disposed on a middle portion of the electrode such that the distal tip and the proximal end of the electrode is not covered by the insulation material,
an electrocautery device body formed from a device body material, the electrocautery device body comprising:
a lower portion radially disposed upon the insulated electrode; and
an upper portion formed as a single unitary piece with the lower portion, wherein the upper portion defines a gas delivery assembly comprising:
a first portion formed at the proximal end of the upper portion, the first portion comprising a gas supply connection, wherein the gas supply connection is configured to receive gas from a gas supply source; and
a second portion distal to the first portion, the second portion defining a gas delivery channel; and
a gas tip coupled to and extending distally from a distal end of the second portion;
wherein the gas delivery channel is in fluid communication with the gas supply connection such that, when the gas supply source is coupled to the gas supply connection, the gas delivery channel is configured to deliver a gas provided by the gas supply source to the biological tissue via the gas tip.
