Disposable Electrosurgical Pencil

Disposable electrosurgical pencil is mainly used in electrosurgery procedures. Through the usage of electrosurgical pencils, the surgeon can control the bleeding via radio frequency alternating current. Usually, the surgeon can adjust the cut or coagulate setting through the electrosurgical pencil’ s push buttons. Disposable electrosurgical pencils are available with either push-button or rocker switch controls to accommodate the surgeon's preference. Surgeons can hear and feel the switch engage, preventing accidental activation of the device. Slim and lightweight, tapered ergonomic design, streamlined design. Slip-proof handling and water resistant rocker or push-button switch. Switch and buttons designed for smooth activation. Equip with a range of monopolar cutting and coagulation electrodes to satisfy all users requirements. With hexagonal shape to protect against inadvertent twisting, the electrodes can be locked safely into place and are easily exchanged and replaced. The division of the tissue is generally done by the electrical sparks that directs intense heat to the surgical application site. A maximum current concentration will be generated by the surgeon through this effect. The surgeon generates the electric spark by holding the electrode slightly a bit from the body tissue and thus, a large amount of current is produced in a short time period that vaporizes the tissue. Fulguration ( also regarded as spray) and coagulation( pinpoint) are the 2 types of coagulation.In the pinpoint coagulation, the surgeon usually holds the electrode in direct contact with or away from the tissue. Fulguration is a type of non-contact coagulation method where electric current sparks from the active electrode to the body tissue. Usually, the surgeon holds the electrode a few distance away from the body tissue, thus the delivered radio frequency current creates a spark across the airgap which is in contact with the tissue. Less heat is generated.It creates coagulum instead of cell vapourisation. When the body tissue comes in touch with the electrode, the procedure is known as desiccation. Through this contact, there is a decrease in current concentration. Drying of body cells happens, thus forming a coagulum. These monopolar cautery pencils serve the purpose of cutting the tissue and controlling the bleeding which leads to coagulation at the body surgical site.

Match with electrosurgical generator(Unit), radio frequency generator(Unit) and other high frequency equipment. These devices are designed to be used as accessories in conjunction with those electrosurgical units and electrodes. These devices are single use supplied sterile. Check plug matching on generator base and connect. Press CUT/yellow button for cutting and COAG/blue button for coagulation. Maximum voltage is not be exceed 90KV peak.The disposable electric surgical pen is used during common surgical operations to cut and cauterise human tissue, and consists of a penlike shape with a tip, handle, and connecting cable for electrical heating. The first stage of the redesign involved ergonomic research, so the team could understand which areas were a priority to improve the performance of the device. The ergonomic styling needed to be addressed to make it more comfortable and better balanced during use. Industrial designers developed a shape that could be well supported in the hand while rotating at different angles, with materials that gave sufficient friction to prevent slipping. Lighter soft materials were chosen for the connecting wires, which also helped improve comfort and the overall balance of the device. Heavy wiring in the previous device had caused over-balancing problems. Feedback from surgeons suggested the cutting devices were prone to sticking to bodily tissues when cutting, causing an unpleasant burning smell. In order to overcome this, we explored special high-temperature biochemical coatings and selected a high-conductivity, non-stick coating that offered a better non-stick blade solution than Teflon. This coating was able to greatly reduce adhesion and odour problems. It also created a special structural design for the device, making the cutting tool free to be adjusted and extended according to the type of tissue it was cutting. Other similar devices on the market had tried to tackle this problem by allowing the blade to be pulled out for greater length, but surgeons had found these products lost stability with the blade moving within the device. As the device was to be disposable, it fully explored safety options to avoid re-use.

Disposable electrosurgical pencil , this is a relatively common medical instrument used in surgery. The main function of the pencil is to electrocut tissue and electrocoagulate blood. There are two kinds of disposable electrosurgical pencil , respectively hand control and foot control. The yellow button on the manual pen represents cutting and the blue button represents clotting. There is no button on the foot control pen, but there is a color display on the foot switch, where the yellow pedal represents cutting and the blue pedal represents clotting. Evaluate whether the patient is suitable for the use of electric knife, select the appropriate brand of electric knife according to the operation, and check whether the power supply and electrode cables are broken and metal wires are exposed. Select and check the negative plate, check the wire and chuck; Choose the size and shape of the appropriate negative plate (15KG infants should choose special plates for infants), check the adhesive force of conductive glue. Assess the patient's skin, select the appropriate site to install the negative plate and connect the negative plate plug to the machine. Connect the electric pen with the machine, start up the self-test, show that the plate is installed correctly without alarm indication, adjust the output power. After use, correctly shut down and remove the negative plate, check the skin below the plate, and clean the electric knife and pen with wiping method (no blister washing).The electrode can be sterilized by high temperature and high pressure method (134℃ 3-5 minutes, 121 ℃ 10-20 minutes). Disinfection with ethylene oxide: after packaging, put the medal in 16-24 hours, and can be used after degradation in the air environment for one hour. Soak in 2% glutaraldehyde for 30 minutes and rinse with normal saline (using this method will affect the service life of the electrode). Before using the electric knife, the tool head should be installed before checking the electric knife loop (energized). Energized is also a secondary disinfection process. It is recommended to choose surgical accessories that can be sterilized at high temperature. Sterilization at high temperature and high pressure (134 degrees Celsius) is more effective and efficient. For example, electric coagulation forceps can be disinfected at high temperature, hand control knife can be disinfected at high temperature.
