surgical pen



Doctors and experts around the world are getting attempts to find improved ways to battle malignancy. Innovations in neuro-scientific science to take care of this fatal disease happen regularly.

With regards to dealing with cancer, cosmetic surgeons want to eliminate as many cancerous cells as you possibly can during tumor removal. Now a fresh technology — how big is a pen — is wanting to make that easier by distinguishing between tumors and healthy tissues in only 10 seconds.

A team of scientists and engineers at the University of Texas at Austin has invented this powerful tool that rapidly and accurately identifies cancerous cells during surgery, delivering leads to about 10 seconds — more than 150 times faster than the prevailing technology.

The MasSpec Pencil can be an innovative handheld device that gives doctors exact diagnostic information in what tissues to cut or protect, assisting improve treatment and decrease the chances of tumor recurrence.

“If you speak to cancer patients after surgery, main things many will say is that they wish the surgeons got all the tumor away,” said Livia Schiavinato Eberlin, an assistant teacher of chemistry at UT Austin who designed the analysis and led the team.

“It’s just heartbreaking when that isn’t the situation. But our technology could greatly improve the chances that surgeons do remove every last track of cancers during surgery,” Eberlin added.

More about these devices:

In a report published in the journal Science Translational Medicine, the researcher’s statement that their handheld device (which is not yet FDA-approved) uses tiny droplets of water to analyze human tissue samples for cancer

The MasSpec Pencil produces a little drop of water that extracts molecules from someone’s cells during surgery

Through machine learning, the MasSpec Pencil can know what molecular fingerprint is normal and what’s cancer

In the scholarly study, the analysts tested 253 human tissue samples from lung, ovary, thyroid, and breast cancer tumors and compared these two samples of healthy tissues
These devices were 96 % accurate at identifying cancerous tissues

The research workers also tested the MasSpec Pen in live mice with tumors and discovered that the device could identify the existence of cancer without harming healthy encircling tissues

These devices can also identify different subtypes of lung and thyroid cancer, and the team hopes to make it more specified for other styles of cancer, too

The experts say they have to continue validating their work and they plan to begin clinical testing in humans in 2018
