#Patients Will printed Swallow 3d Tadpole Endoscope That Provides Diagnosis of Cancers A team from the Institute of Precision Engineering at the Chinese University of Hong kong has developed 3d-printed tadpole-like devices that can improve diagnosis of various cancers by entering the patient stomach and wirelessly transmitting images of what it sees. The new 3d-printed device, called the Tadpole Endoscope, is a reliable and relatively noninvasive solution that could improve cancer diagnosis. Developed to be swallowed just like a large pill (it is a bit bigger than a small coin), the TE begins to work immediately and can be controlled remotely all the way through the patient digestive track. Researchers were inspired by the mechanics that move tadpoles underwater. The TE drive unit is constructed with two permanent magnets with opposing polarities and a magnetic coil. When energized, the coil generates a repulsive and attractive force that can propel the TE, mimicking tadpoles in nature. While similar devices known as wireless capsule endoscopes have been created in the past, the TE is notable for its soft tail, which allows it to be guided deftly around the entire stomach by the doctor and the 3-printed shell, which houses control electronics and the video camera holder o
