Japan latest surgery "navigation" system for accurate positioning of lymph node

Japan Kochi University recently released a communique says that researchers developed in operation in perspective in lymph nodes, vascular and other organizations of the "navigation" System.

When in operation, using the system you can use a color image clearly observing the State of the organization.

The Communique says, usually in cancer surgery to confirm the location of the lymph nodes and other tissues is difficult.

If you use this operation the "navigation" system, we can solve the above problem, through minimal for the treatment of patients.

The Communique says, a indocyanine green pigment has absorbed light will glow.

Kochi University Professor SATO Takashi fortunately led the research team used the pigment of this characteristic, indocyanine green subcutaneous injection into the body of the lymph nodes and blood vessel, and then use near-infrared irradiation from in vitro, indocyanine green in lymph nodes and vascular inner glow.

Because this kind of light visible to the naked eye cannot see, the research team also developed the ability to capture faint ray of ultra high sensitivity camera.

Use the monitor observation camera to take a color image, you can clearly see the glow of the blood vessels, lymph nodes and surrounding organs, thus accurately related organizations and organs of the location and operation.

Researchers said that although the use of ionizing radiation are also able to confirm that the lymph nodes and blood vessel position, but this approach will allow patients affected by weak radiation treatment establishments thus restricted.

And near-infrared and indocyanine green harmless to the human body, can be used multiple times, the patient has been greatly reduces the burden.

According to reports, Kochi University Medical Department has utilized the system successfully in more than 100 cases of breast cancer surgery and accurate location of the discovery of the lymph nodes.

In addition, the system can also be used to confirm the location of liver cancer, cardiac surgery is also expected to be applied.
