DETAILED DESCRIPTION

(5) Portable device, used specifically for electrofulguration and electrodesiccation is composed of applicator 1 with a precisely aiming end, which has a gilded and detachable tip. There is an indicator 2 of the spark discharge (FLASH), button 3 for Play/Pause, which ignite and extinguish the spark discharge. Moreover, there is the indicator 4 of the effectivity of the spark discharge (this is the electricity that passes through the patient), then indicator of the intensity of the spark discharge 5 (it is marked Energy on the display) and a dash 6 before and after the numeric value of the intensity of the spark discharge. It also entails On and Off Buttons 7, socket 8 for connecting the grounding cable to the neutral electrode that is conductively connected with the patient and an On indicator 9. The equipment also entails a socket 10 used for plugging into adapter, a button 1 for switching into lower intensity of the discharge and a button 12 for setting a higher intensity of the discharge.

(6) Portable electrocauter is provided with the source of DC with the maximal current of 1 mA and voltage 0.8 to 12 kV, the applicator 1 is provided with exact aiming finish and the patient is conductively connected with the device though disposable grounding electrode, while the output power between the working electrode and the surface of the skin is in the range of 0.3 to 4.0 W.

(7) The applicator 1 is provided with gilded removable tip. The source of the DC is battery.

(8) Spark discharge of the tip is linked, which is in contrast to electrocauters on AC.

(9) Standard Technical Parametres:

(10) Electrical Supply: 100 to 240 VAC/50-60 Hz

(11) Class of Protection against Electric Shock: II

(12) The Type of Device: with applied part type BF

(13) The Type of the Supply Source: DA 12-050EU-M, manufacturer EMERSON

(14) Power Supply Input: 100-240 V/50-60 Hz

(15) Power Supply Output: 5 VDC, max. 2.0 A

(16) Output of Power Supply: max. 12 W

(17) The Voltage of the Generator of the Plasma Discharge: 0.8-12 kV

(18) Output of Plasma Discharge: 0.3-4.0 W

(19) Detection of the Functionality between the Neutral Electrode and the Patient: system SCS

(20) Automatic Turning Off of the High Voltage of the Tip of the applicator: after 20 seconds

(21) Accelerated Lowering of the Voltage to 0 on the Tip of the applicator after Turning Off: after 1 sec

(22) Dimensions: length 245, width 45 mm

(23) Weight: approx. 350 g

(24) The Level of Coverage: IP2X

(25) A portable device used especially for electrofulguration and electrodesiccation is equipped with applicator 1 which is provided with long-distance glass tube, in accordance with CZ utility model n. 27650. Using the long-distance glass tube achieves that the constant distance of 2 mm from skin of the patient is sustained. This means that, as a first device on the world, it is able to produce the spark shower in a very thin volume and at the same time keep the distance of 2 mm from the skin.

(26) A great advantage is the inner diameter of the glass tube, which is 0.3 mm. At such a value of the inner diameter of the glass tube, the spark discharge can be precisely aimed. Spark discharge burns when the intensity is at the levels 7-8 while the distance is 4 mm, which means that the head of the tube will be 2 mm over the area treated. Spark discharge is even more precisely aimed due to the glass tube. The idea of aiming the spark tube by glass tube is to be protected.

(27) System automatically evaluates if the patient (client) is connected to the equipment via self-adhesive electrode. This way, possible burns can be avoided, which could occur if the patient is disconnected from the device. The method of the identification is to be protected—as per the block schema.

(28) Electrocauter, based on this invention, will find its use in various fields of the medicine, especially for treatment of pathologically changed tissues. It could be used in dermatology but also in stomatology, surgery, gynecology, proctology, urology, otorhinolaryngology and many other fields where it is necessary to get rid of pathological tissues or to destroy cells by means of electrodesiccation or where there is necessary to stop a small bleeding. It is meant to be used for the treatment of face for precise removal of skin artefacts or to perform fulguration-type of microburns to the skin around the wrinkles. The skin will smooth during the healing of these microburns.
