An electrical scalpel is a surgical device that uses high-frequency electrical currents (greater than 200,000 Hz) to cut or clot tissues and cauterize them simultaneously. This equipment consists of an electrosurgical generator that transforms the electrical energy into high-frequency current and is activated with a specific command.
Electric scalpels are designed to perform multiple functions and feature several types of electrodes, which vary depending on surgical applications. According to its structure it has two modes of operation. The monopolar mode of operation, where the active electrode is the one involved in the process, since who concentrates the energy at the point of contact. And the operation of bipolar mode involves the action of two electrodes, and they are normally presented in the form of a hemostat
Monopolar Electroscalpel
This equipment works through a single active electrode, which also performs the function of neutral electrode. This electrode contacts biological tissue, which transmits high-intensity electrical current from the electrical generator. This high concentration of energy in a small area achieves the desired effect. The current then passes through the patient’s body to the neutral electrode, closing the electrical circuit.
It is the most widely used monopolar electroscalpel because it is very effective. In monopolar electrodes, the radiofrequency current flows from the generator through the active electrode, into the target tissue, through the patient, the dispersive electrode, and then back into the unit. The most common injury site is where the patient’s return electrode is placed. It is a technique that is advised for simpler surgical procedures when taking appropriate caution, and while working near critical organs.
Bipolar Electroscalpel
Bipolar electroscalpels have a lower power density than monopolar electroscalpels, which means that they cannot cut tissue (with some exceptions). They are commonly used for endoscopic applications or to seal blood vessels. In the bipolar electroknife, two electrodes of equal size are attached to the instrument, this makes it unnecessary to disperse the current, so the electrode back to the patient is not used either. In this type of electrical scalpel technique, high-frequency current flows through an active electrode and out the neutral electrode, bypassing the patient’s body. The most commonly used instrument for this technique is the bipolar clamp, which allows the active and neutral electrodes to be placed in front of each other. The current then passes directly from one end of the clamp to the other. The neutral electrode has no function here.
Most of these electrical scalpels use a lower voltage waveform to achieve coagulation and prevent collateral tissue damage. Advantages include lower thermal dispersion, shorter dissection time, better seal quality, less blood loss, lower conversion rates, and higher profitability than monopolar electrosurgery. It is safer than a monopolar electric scalpel because it reduces the risk of burns or electrocution. It is suitable for use in patients who have an implanted pacemaker.
