HYDERABAD, AUG 4: Scientists of Defence Metallurgical Research Laboratory (DMRL) here have successfully developed technology for indigenous production of surgical tool called `Gigli Saw'.

Gigli Saw, which is used for cutting hard tissues and finds prolific use in orthopaedic and neurosurgical procedures, is of a very simple construction, basically resembling a wire rope with two strands, each consisting of two wires.

The pitch of twist in each strand is critically controlled in such a way that the surface of the rope is rough with ridges and valleys, a feature that promotes cutting action, Dr A Venugopal Reddy, head of Materials Sciences division, DMRL, said in a statement here today.

The novel technology uses specially selected stainless steel wire available locally and a special machine designed and developed by the laboratory for making the saw, he said.

During the entire technology development phase, inclusive of conducting performance trials, the neurosurgeons of National Institute of Mental Health and Neuro Sciences, Bangalore, and Nizam's Institute of Medical Sciences (NIMS) Hyderabad, worked closely with the scientists of DMRL.

The scientists of DMRL, who successfully developed critical biomedical devices like `Kalam-Raju' cardiovascular stent in the past, were also working on the development of many more critical implantable devices which meet the international quality requirements, Reddy said.
