Apparatus and method providing a hand-mounted surgical tool

An apparatus comprising:

• a housing configured to be mounted to a body of a user;
• an electrode coupled to the housing such that a tip of the electrode is configured to move from a first position relative to the housing to a second position relative to the housing;
• a power source electrically connected to the electrode;
• a processor communicatively coupled with the power source;
• at least one memory including one or more sequences of instructions,
• the at least one memory and the one or more sequences of instructions configured to, with the at least one processor, cause the apparatus to perform at least the following,
• receive a first signal from a first user input device based on a first user input received from the user;
• transmit a second signal to the power source to cause the power source to deliver electrical power to the electrode based on the received first signal;
• receive a third signal from the first user input device based on an input received from the user;
• and
• transmit a fourth signal to the power source to cause the power source to stop delivering electrical power to the electrode based on the received third signal;
• wherein the housing comprises:
• a first housing configured to be mounted to a finger of the hand;
• a first attachment slidably received within a first slot defined by the first housing, wherein the first attachment defines a slot or opening to receive the electrode:
• a second housing configured to be mounted to a wrist of the hand:
• and
• a second attachment slidably received within a second slot defined by the second housing, wherein the second attachment defines a slot or opening configured to pass electrical cables connected to the electrode.
