In the world of veterinary surgery, precision and efficiency are paramount. Choosing the right tools can make all the difference in the outcome of a procedure, and two of the most used devices are vessel sealers and electrosurgery units (ESUs). Both have their unique advantages, but when it comes to sealing and cutting vessels during surgery, one clearly stands out. Here’s a closer look at the differences between vessel sealers and electrosurgery units to help you make the best choice for your practice.
Understanding the Big Picture
Vessel Sealers:
Vessel sealers are specifically engineered to seal and cut vessels during surgery. These devices provide real-time feedback, alerting you when a vessel is adequately sealed. This feature significantly reduces the risk of human error and ensures a secure seal every time. Once the vessel is sealed, you can either proceed to seal another area or use the integrated blade to cut through the sealed tissue. This efficiency is particularly beneficial in complex surgeries, as it reduces blood loss and shortens the duration of the procedure.
Electrosurgery Units:
However, electrosurgery units are designed mainly for cutting and cauterizing tissue using monopolar or bipolar currents. While they can cauterize vessels, they lack the real-time feedback that vessel sealers provide. This absence of feedback can lead to either weak seals, increasing the risk of bleeding, or overly strong seals, causing collateral damage and charring of the tissue. For this reason, vessel sealers are generally recommended over electrosurgery units for most vessel-sealing applications, as they offer a higher level of safety and reliability.
Technical Details: The Science Behind the Tools
Vessel Sealers:
Vessel sealers are cutting-edge tools used in both open and laparoscopic procedures to coagulate and cut tissue and vessels. The Voyant generator, for example, continuously monitors the tissue between the instrument’s jaws, analyzing the hydrogen bonds within. The device breaks down these bonds to create a sticky coagulum, sealing the tissue or vessel without charring. Once coagulation is complete, which takes only a few seconds, the user can activate the blade with a simple trigger, cutting the sealed tissue in one smooth motion. This process is not only efficient but also easy to learn, making it accessible for any veterinary surgical team.
Some common procedures where vessel sealers excel include:
- Spay and neuter surgeries
- Splenectomy
- Pyometra resection
- Leg amputation
- Mammary chain mass removal
- Soft palate resection
Electrosurgery Units:
Electrosurgery units, in contrast, are often used for cutting through skin, fat, and muscle, acting as a versatile alternative to the scalpel. They are particularly useful in quickly dissecting tissue while cauterizing smaller vessels to minimize bleeding. However, these units do not provide feedback on the quality of the seal or cut, and improper use can result in charred tissue. Additionally, electrosurgery units are not suitable for laparoscopic procedures, an area where vessel sealers truly shine.
