ROBOTIC DRILL FOR CRANIAL SURGERY

A latest robotic drill performs a kind of complicated cranial surgery fifty times more rapidly than ordinary procedures has been developed by scientists together with one among Indian origin. The Mechanized drill is similar to  automobile elements that provide quick, clean and safe cuts, reducing the time the wound is opened and also the patient sedation time

This can reduces the occurrence of infection, human faults, and surgical expenses. To perform complicated surgeries, particularly cranial surgeries, surgeons generally use hand drills to form labyrinthine openings, which takes many hours to complete. The mechanized drill reduces the time for bone removal from 3 hours to 2.5 minutes.

First, the patient is imaged employing a CT scan to collect bone information and determine the precise location of sensitive structures, like nerves and major veins and arteries that has got to be avoided. Surgeons use this statistics to monitor the cutting path of the drill. The software allows the surgeon to select the optimum path from purpose A to purpose B as in the Google maps. It also allows the surgeon to programme safety barriers along the cutting path within one millimeter of sensitive structures

The translabyrinthine surgery is performed thousands of times a year in order to remove benign tumors that form in the region of the auditory nerves. This surgery is very complicated such that the cutting path should avoid numerous sensitive features, including facial nerves and the venous sinus (a large vein that drains blood from the brain). Risk factor of this surgery is loss of facial movement. In order to avoid this risk factor the mechanized drill consists an automatic emergency shut-off switch to avoid contact with the facial nerve. If the mechanized drill gets too close to the facial nerve then the drill automatically turns off.
