Abstract: Proposed is a smoke pencil with swivel device, in which first end portions of first and second cases are rotatably coupled to a body and second end portions of the first case and the second case are inclined downward, so when a user rotates the body, a cable and a suction hose are guided downward. Accordingly, there is an effect that a user can easily rotate the body.

Abstract: Proposed is a smoke evacuation device with fluid storage for laparoscopic surgery that can easily filter fluid produced during an operation. According to the smoke evacuation device with fluid storage, water produced in a main body cannot flow back to a filter, so the performance of the filter is not deteriorated and noxious fluid flowing into the main body can be easily filtered out.

Abstract: An electrosurgical apparatus comprises: a main body formed with a suction passage therein; an extension member including a length adjusting tube coupled to a side of the main body and formed therein with an induction passage communicating with the suction passage, and a sliding part configured to slide while being guided by the length adjusting tube; and a blade configured such that a first end thereof protrudes outside through the sliding part, and a second end thereof extends to be electrically connected to the main body and receives high frequencies from the main body, wherein an entire length of the extension member is adjusted according to a position of the sliding part sliding along the length adjusting tube.

Abstract: An electrosurgical device having an easily adjustable length, in which the entire length of the device can be easily adjusted by allowing a stretching member having a blade to be easily moved in a body by unlocking the stretching member in a one-touch button type. Therefore, an operator can easily insert the blade inside incised skin of a patient.

Abstract: A conductive hydrogel includes: a first monomer; a second monomer; a crosslinking agent; a photoinitiator; a wetting agent; an electrolyte; and deionized water, wherein the first monomer is a 3-sulfopropyl acrylate potassium salt, and the second monomer is acrylic acid. The conductive hydrogel has high adhesivity, conductivity and moisture-retaining capacity and low skin irritancy compared to conventional hydrogels because it has the optimum composition ratio.

Abstract: A disposable tab electrode has core elements that include an adhesive conductive laminate layer and a logo sticker layer with a penetrating hole for contacting a sensor electrode. A protecting film is put around both ends of the core elements. As a result, the disposable tab electrode can be made inexpensively, stored hygienically for a long time and used easily. A lead wire for connecting to the tab electrode has a projection on one end of a sensor electrode that is adhered onto the conductive laminate layer of the disposable tab electrode. The projection is fixed to the lead wire body by a fixing member. As a result, expensive Ag—AgCl electrode sensors can be used repeatedly. The lead wire can have a nipper self-contained or integrated with the lead wire body to prevent the lead wire from separating from the disposable tab electrode during use.
