The second coating supplies, a high-frequency current to an object to be treated. The medical device also includes a laminated portion that includes the first coating in the outer surface of the base extends and a portion of the second coating that is laminated on the first coating.

A surgical system includes an active terminal, a return terminal, an active electrode, a return electrode, an active plug configured to connect to the active terminal, and a return plug configured to connect to the return terminal. The return plug is coupled to the return electrode and coupled between the active plug and the active electrode. The return plug is configured to break an electrical connection between the active plug and the active electrode when the return plug is not connected to the return terminal and to establish an electrical connection between the active plug and the active electrode when the return plug is connected to the return terminal.

Lighting devices are disclosed for use with handheld surgical instruments, along with holsters for supporting surgical instruments with lighting devices thereon and kits containing surgical instruments and lighting devices.

An electrosurgical instrument includes an elongated first shaft fabricated from thermally-conductive plastic material, an elongated second shaft, and opposing first and second jaw members each having a proximal end portion coupled to a distal end portion of the respective first and second shafts. One or both of the jaw members has a jaw frame and an electrically-conductive tissue sealing structure disposed over the jaw frame. The first shaft has a heat sink disposed therein configured to dissipate heat from the tissue sealing structure toward the thermally-conductive plastic material.

Disclosed are a radio frequency operation prompting method, an electronic device, and a computer-readable storage medium. The method includes acquiring physical characteristic data of an operating position in an object of a radio frequency operation in real time by multiple probes, obtaining a physical characteristic field of the object of the radio frequency operation according to the physical characteristic data acquired in real time; and obtaining a change of range of a to-be-operated area in a target operating area according to an initial range of the target operating area in the object of the radio frequency operation and a change of value of the physical characteristic data in the physical characteristic field, and displaying the change of range through a three-dimensional model.

An elongate electrode is configured to flex and generate plasma to incise tissue. An electrical energy source operatively coupled to the electrode is configured to provide electrical energy to the electrode to generate the plasma. A tensioning element is operatively coupled to the elongate electrode. The tensioning element can be configured to provide tension to the elongate electrode to allow the elongate electrode to flex in response to the elongate electrode engaging the tissue and generating the plasma. The tensioning element operatively coupled to the flexible elongate electrode may allow for the use of a small diameter electrode, such as a 5 μm to 20 μm diameter electrode, which can allow narrow incisions to be formed with decreased tissue damage. In some embodiments, the tensioning of the electrode allows the electrode to more accurately incise tissue by decreasing variations in the position of the electrode along the incision path.

Systems, instruments, and methods for minimally invasive procedures including one or more of fractional resection, fractional lipectomy, fractional skin grafting, and/or fractional scar revision are described. Embodiments include instrumentation comprising a scalpet assembly coupled to a carrier, and the scalpet assembly includes a scalpet array. The scalpet array includes one or more scalpets configured for fractional resection, fractional lipectomy, fractional skin grafting, and/or fractional scar revision. The system includes a vacuum component coupled to the scalpet assembly and configured to evacuate tissue from the a site. The carrier is configured to control application of a rotational force and/or a vacuum force to the scalpet assembly.

Systems, instruments, and methods are described in which an apparatus comprises a housing including a scalpet device. The scalpet device includes a scalpet array that includes scalpets arranged in a pattern. The scalpets are deployable from the housing to generate incised skin pixels at a target site. The housing is positioned and the scalpet array is deployed into tissue at the target site. Incised skin pixels are generated when the target site is a donor site, and skin defects are generated when the target site is a recipient site. The incised skin pixels are harvested.

An end effector of an electrosurgical device may include a first body, a first electrode on the left side of the first body, and a second electrode on the right side of the first body. The first and second electrodes may be configured to receive electrosurgical energy to treat tissue in a target treatment zone. The end effector may also include a fluid aspiration port in fluid communication with a fluid path. The fluid aspiration port may be configured to remove a material from the target treatment zone.

A surgical system that illuminates a surgical site using one or more illumination means is powered by radiofrequency energy produced by an electrosurgical generator. Illumination may occur whether or not current is being delivered from an active electrode to target tissue.
