ELECTROSURGICAL UNIT

ESU is a versatile system meeting all operating theatre requirements. It is equipped with a fast microprocessor, processing all operating parameters in real time. It enables fast automatic current adjustment to changing operating conditions. Electrosurgical units (ESU) use a high-frequency electrical current to cut tissue and control bleeding by causing coagulation. Tissue resistance to the high-density current causes a heating effect which results in tissue destruction. Electrical current is delivered and received through cables and electrodes. The electrodes may be activated by either a handpiece switch or a footswitch. The ESU may use a monopolar or a bipolar mode. Special modes enable operation in difficult conditions, laparoscopy, and endoscopy. These systems include an electrosurgical generator (i.e., power supply, waveform generator) and a hand piece including one or several electrodes.

PRINCIPLES OF OPERATION

In monopolar electrosurgery, tissue is cut and coagulated by completion of an electrical circuit that includes a high frequency oscillator and amplifiers within the ESU, the patient, the connecting cables, and the electrodes. In most applications, electric current from the ESU is conducted through the surgical site with an active cable and electrode. The electrosurgical current exits the patient through a dispersive electrode (usually placed on the patient at a site remote from the surgical site) and its associated cable connected to the neutral side of the generator. In bipolar electrosurgery, two electrodes (generally, the two tips of a pair of forceps or scissors) serve as the equivalent of the active and return electrodes in the monopolar mode.

FUNCTIONS

  • The percentage output digital display shows on the front panel.
  • Self-test of the generator and accessories after switching the power on
  • It is controlled by Microprocessor which is responsible for controlling and monitoring of all functions and features in unit.
  • Output values (CUT, COAG, BIPOLAR) are remained in the memory after switching off. These values will be come up to the display at turning on the power
  • Automatic Bipolar output without using footswitch
  • Multi monopolar outlets can be used for two hand control outlets and for one laparoscope outlet
  • This can be hand or foot operated
  • Versatility, Reliability
  • Designed for safety/ Designed for ease of use
  • Accessibility to parts and ease of maintenance that is unsurpassed
  • A bipolar output power profile that provides good resolution to permit small changes in power levels for delicate work, yet has sufficient maximum output power capability to satisfy the requirements of the more demanding Procedures
  • Spray Coagulation provides the Trans Urethral Resection(T.U.R) and Endoscopic procedures in urology
  • monopolar cutting, Monopolar coagulation, Bipolar cutting, Bipolar coagulation, spray coagulation and Vessel sealing modes
