Smart knife to modify surgery

The  smell of burnt flesh rises in the operating theatre and the smoke from vaporised tissue is sucked away. But these fumes are diverted into a machine that tells the surgeon exactly what is being cut into, guiding the rest of the operation. This is “smart surgery“, and it holds the potential to transform medicine. This is the first NMR spectrometer in the world which does the work of a histologist.who identifies the tissue being cut/taken out.

The process tends to take about 40 minutes, and is subject to human error and variability. To standardise and speed up tissue identification, Jeremy Nicholson and his colleagues at Imperial College London have brought nuclear magnetic resonance spectroscopy – a chemistry-lab staple – into St Mary’s Hospital in London.

BIOMEDICAL ARTICLES PART-2 DEFIBRILLATOR,PACEMAKER, DIATHERMY & ELECTROSURGICAL UNIT (ESU)

DEFIBRILLATOR & PACEMAKER

Defibrillator is a device that delivers a therapeutic dose of electrical energy to the affected heart.

This depolarizes a critical mass of the heart muscle and allows normal sinus rhythm to be reestablished by the body’s natural pacemaker of the heart.

Pacemaker

It is a medical device which uses electrical impulses, delivered by electrodes contacting the heart muscles, to regulate the beating of the heart.

DIATHERMY

The term diathermy means “electrically induced heat” and
is commonly used for muscle relaxation. It is also a method
of heating tissue electromagnetically or ultrasonically for
therapeutic purposes in medicine.
