Invisible Knife Promises to be a Boon for Micro-surgery

Engineers from University of Michigan have created a new ultrasound technology that promises to be a boon for micro-surgery.

Using a carbon nanotube coated lens, researchers found that light energy can be converted to high pressure sound waves, to help focus on precise points.

Accurate Diagnosis of Cirrhosis from Recurrent Hepatitis C Possible With Ultrasound Technology
Mayo Clinic researchers confirm ultrasound-based transient elastography (TE) provides excellent diagnostic accuracy for detecting cirrhosis from recurrent hepatitis C

Researchers have called it the ‘Invisible Knife’ and feel that it can be used in medical research fields like noninvasive surgery. Engineers used tightly-focused sound waves for micro-surgery with which they were able to drill a 150-micrometer hole in a minute artificial kidney stone. They were able to focus high-amplitude sound waves to tiny dot.

According to Jay Guo, a professor of electrical engineering and computer science, mechanical engineering, and macromolecular science and engineering, this research will be the gateway to many more inventions in this area and perhaps even a way to “probe cells or tissues in much smaller scale.”

Breakthrough in Autonomous Robot Surgeries
