Mesenteric Vessel Sealing by Three Instruments

2014-07-23 21:09:06 | BioPortfolio

Summary

Ultrasonic cutting-coagulation devices (UCCD) are surgical instruments which use ultrasonic energy to cut through and coagulate tissue. An Ethicon version (trademarked "Harmonic Scalpel" and "Ultracision") is used in a variety of surgical procedures. Its surgical performance has been directly compared with that of electrically powered diathermy instruments in animal and clinical trials. LOTUS is a company based in Ashburton, Devon, which has developed a UCCD that works in a slightly different way to the Harmonic Scalpel. There are also bipolar feedback diathermy instruments which use electrical energy to seal blood vessels, such as LigaSure. The aim of this project is to obtain data to design a fully powered trial to answer the research question: do LOTUS and Ethicon UCCDs and LigaSure bipolar device reliably seal and divide blood vessels? The investigators will also be examining the degree of collateral tissue damage caused by each instrument.

Hypotheses

- LOTUS UCCD, Ethicon Harmonic Scalpel and LigaSure are equivalent at sealing and dividing mesenteric blood vessels.

- LOTUS UCCD, Ethicon Harmonic Scalpel and LigaSure cause equal amount of collateral damage when sealing and dividing blood vessels.

Medical and Biotech [MESH] Definitions

A microscopic imaging technique that takes advantage of the process of harmonic generation that occurs when photons interact to generate new photons of a different wavelength. In second harmonic generation, two photons of the same wavelength and frequency, such as from a LASER, interact inside a medium and are converted to a photon of twice the frequency and half of the wavelength of the two incident photons. The light signals captured are used to produce images that are dependent on the unique optical properties of the material.

A plant genus of the family NELUMBONACEAE. The common name of lotus is also for LOTUS and NYMPHAEA.

Not an aneurysm but a well-defined collection of blood and CONNECTIVE TISSUE outside the wall of a blood vessel or the heart. It is the containment of a ruptured blood vessel or heart, such as sealing a rupture of the left ventricle. False aneurysm is formed by organized THROMBUS and HEMATOMA in surrounding tissue.

A tribe of the PEA FAMILY. The genus Lotus, a member of this tribe and formerly known as Tetragonolobus, is unrelated to other plants with the common name of lotus (NELUMBO and NYMPHAEA).
