Electrosurgical scalpel LIGASURE - Good

ValleyLab LIGASURE Electrosurgical Unit: Precision and Safety for Coagulation and Suturing in Surgery.

The ValleyLab LIGASURE electrosurgical scalpel offers an advanced vessel sealing system capable of handling vessels up to 7 mm in diameter, lymphatics, and tissue bundles of varying sizes. This system delivers precise energy and electrode pressure to the vessels over a controlled time period, ensuring complete and permanent tissue fusion. Unlike traditional methods, the LigaSure system minimizes sticking, charring, and thermal spread to adjacent tissue, enhancing surgical precision and safety.

In addition to vessel sealing, the ValleyLab LIGASURE system provides versatile bipolar modes suitable for various applications. The bipolar mode maintains low voltage to prevent sparking while delivering consistent power over a specific tissue resistance range, ensuring a uniform tissue effect. Moreover, the macrobipolar mode offers higher voltage and increased power, making it suitable for bipolar cutting or rapid coagulation during surgical procedures.

The unique capability of the ValleyLab LigaSure vessel sealing system lies in its ability to create permanent vessel occlusion by fusing vessel walls. This revolutionary technology replaces conventional hemostatic tools by not only ligating vessels but also forming a durable seal that withstands physiological pressures. The system combines pressure and energy to achieve vessel fusion, eliminating the need for dissection or isolation of vessels.

With an average seal cycle of 2 to 4 seconds, the ValleyLab LigaSure system offers rapid and efficient vessel sealing, enhancing surgical efficiency and reducing procedure time. The seals produced by the system can withstand up to three times normal systolic blood pressure, ensuring reliable hemostasis. Moreover, the feedback-controlled response system automatically discontinues energy delivery once the seal cycle is complete, eliminating guesswork and enhancing safety during surgical procedures.

The output waveform of the ValleyLab LigaSure system is optimized for effective vessel sealing and bipolar operations. The system operates at a frequency of 473 kHz sinusoid with a 100% duty cycle for macrobipolar/bipolar modes, while the seal mode utilizes a pulsed 473 kHz sinusoid waveform. Additionally, the system features low-frequency leakage levels, ensuring patient safety and reliable performance during surgical interventions.
