Abstract

Approaches for percutaneous blepharoplasty are provided. An electrosurgical device includes: a hand-piece; a tip connected to the hand-piece; and two needles extending from a distal end of the tip. The hand-piece is structured and arranged to connect to an electrical energy source, and to convey electrical energy from the electrical energy source to the needles in a percutaneous blepharoplasty procedure.

Claims

1. A device, comprising:

a hand-piece;

a tip at a distal end of the hand-piece; and

two needles each having a respective free end extending outward from the tip;

wherein the hand-piece is selectively connectable to an electrical energy source by an attachment that is configured to convey electrosurgical current from the electrical energy source to the hand-piece;

the hand-piece is configured to convey the electrosurgical current to at least one of the needles;

the device is adapted to utilize bipolar electrosurgery with one of the needles serving as the active electrode and another one of the needles representing the return electrode,

the device is adapted such that the electrosurgical current travels through the active electrode, passes through a tissue between the needles, and runs into the return electrode, such that the tissue shrinks and/or retracts as a result of the electrosurgical current;

the tip is rotatable relative to the hand-piece about an axis that is angled relative to a longitudinal axis of the hand-piece;

the hand-piece comprises a finger grip and a thumb grip;

the tip comprises a wedge configured to move relative to and against the needles;

the wedge is moveable to a first position that causes the needles to be parallel to one another, outside a housing of the tip, and spaced apart by a first distance; and

the wedge is moveable to a second position that causes the needles to be at an acute angle relative to one another, outside the housing of the tip, and spaced apart by a second distance different than the first distance.

2. A device, comprising:

a hand-piece;

a tip at a distal end of the hand-piece; and

two needles each having a respective free end extending outward from the tip;

wherein the hand-piece is selectively connectable to an electrical energy source by an attachment that is configured to convey electrosurgical current from the electrical energy source to the hand-piece;

the hand-piece is configured to convey the electrosurgical current to at least one of the needles;

the device is adapted to utilize bipolar electrosurgery with one of the needles serving as the active electrode and another one of the needles representing the return electrode,

the device is adapted such that the electrosurgical current travels through the active electrode, passes through a tissue between the needles, and runs into the return electrode, such that the tissue shrinks and/or retracts as a result of the electrosurgical current;

the tip is rotatable relative to the hand-piece about an axis that is angled relative to a longitudinal axis of the hand-piece;

the hand-piece comprises a finger grip and a thumb grip on opposite sides of a generally cylindrical housing;

the tip comprises a wedge configured to move relative to and against the needles;

the wedge is configured to move from the first position to the second position based on a squeezing force applied to the finger grip and the thumb grip; and

the wedge is configured to move from the second position to the first position based on the squeezing force being released.
