Innovative instruments for surgery cancers

In this article you will learn the best practices and devices to identify malignant cells, oblegchayuschimm surgeons to conduct complicated operations to remove them. Innovative technologies allow to clearly distinguish diseased cells from healthy, which significantly reduces the need for repeated operations.

Cancer is a scary diagnosis, but thanks to modern surgical technology, the chances of complete remission after tumor removal are getting better every year.

The problem of removing cancer cells is that the surgeon must determine the diseased cells and separate them from the healthy. Excessive removal results in a heavier patient recovery and insufficient removal often results in the repeated operation. To discover the best methods and devices detect malignant cells, facilitating surgeons carrying out complicated operations.

Scalpel operates based on the analysis of lipids, fatty molecules which constitute a large part of the cell membrane. Chemists recent years studies have shown that the ratio of certain lipids may be used to identify a variety of biological tissues, including tumor. The normal procedure requires the removal of tissue and subsequent analysis by mass spectrometry, which explores the weight and structure of charged molecules.

Hungarian Zoltan Takats doctor from Imperial College London set out to, and found that the smoke generated electro-surgical knives for cutting the flesh and cauterization of blood vessels, contains ionized molecules suitable for mass spectrometry. Then it was easier. Electro-scalpel has been equipped with a mass spectrometer, connected to the computer. Smart scalpel called iKnife. Doctor team collected almost 3000 tissue samples from 300 cancer patients and experienced iKnife them. Tests showed that a knife could distinguish the normal tissue from tumor tissue of various organs such as breast, liver and brain. Moreover, iKnife can determine the origin of the tumor, whether the tumor metastasis or consequence of other body parts.

Real research during 81 operations to remove cancers have yielded positive results. Knife read information with a delay of 1 to 3 seconds, which is a good achievement. Surgeons around the world gave their rave reviews of medical novelty.

The new technology developed by a team led by Samuel Achilefu, professor of radiology and biomedical engineering at the University of Washington. Established technology involves the introduction of the fluorescent fluid in the patient's body. The dye makes cancer cells glow blue.

Special video goggles worn by the surgeon, display illumination cells in various shades of blue. The lighter shade of blue, the smaller the number of cancer cells comprises a fabric. The researchers noted that tumor size up to 1 mm in diameter were identified points.

Scientists plan to improve the dye for the purpose, so that he remained longer in the body's cells. American surgeons are beginning to actively promote his creation in the real medicine.
