Scientists invents a ‘smart’ knife to detect tumor


iknifeIt would be very great if tumor location could be detected precisely so that a surgery works better. Well,  scientists now are trying to develop a ‘smart’ knife which is capable of detecting tumors to increase the effectiveness of cancer surgery. If this works well, then this would be a great achievement of the medical world.

Besides locating the precise position, it is important to know whether the tumor had completely been removed after surgery. Therefor the team of scientists from Imperial College London also hope that the knife is capable of narrowing opportunities of remaining tumor in the patient’s body so that it does not grow again and cause new cancer.

This smart knife had done some tests which provided some good results for the future of this modern medical equipment. The knife itself is named the iKnife. This knife had been clinically tested and proven to successfully detect the network that triggers tumor. However, one in five breast cancer patients involved in the clinical trial still need a second surgery to completely clean the tumor from their body. Despite the small setback, this trial had proven that this knife could provide many great benefits for the future medical world.

Apparently, the iKnife had received positive reaction by the medical world. As reported by the BBC, several hospitals around the world have started to use the iKnife. The iKnife itself functions by its ability to distinguish smoke from tissue when dissected.

The smoke is absorbed by the ‘nose’ of the iKnife called the mass spectrometer. The point is to distinguish between smoke from cancerous tissue and healthy tissue. This way surgeons will know the tumor.

In such way, the surgeon can determine exactly which network should be lifted while performing the operation. So that the entire network that trigger tumor can be removed and they can maximize the patient’s recovery.

One of the clinical trials are now conducted at three hospitals in London. The scientists are optimistic that their findings could increase the chance of a longer life for patients with cancer.
