When the Dusky Arion slug feels threatened, it secretes a mucus that makes it almost impossible to remove from whatever surface it happens to be on. Inspired by that, scientists have created an adhesive gel that could conceivably be used in the human body.

A new material could help reduce the risk of bowel perforations or hernias, as surgeons are suturing up incisions in the abdominal wall. The material provides protection during surgery, yet harmlessly dissolves in a matter of hours.

Médecins Sans Frontières (MSF) delivers medical care in the world's most dangerous places. Currently serving in Mosul (Iraq), MSF's new Mobile Unit Surgical Trailer is a complete mobile hospital on a truck that can be operational within three hours, saving time during conflicts or disasters.

A new imaging technique would give doctors the ability to ascertain whether all traces of a tumor have been removed while in the operating room, thus avoiding having the patient return to surgery weeks later for a second procedure.

Current approaches to cranial surgery are painstaking, but researchers at the University of Utah say they have come up with a much more efficient way of doing things, developing a robotic drill that could cut operation times by hours and reduce the risk of infection throughout.

The da Vinci robotic surgical system may be handy, but a high price tag could be out of reach of some hospitals. Now Intuitive Surgical has announced the da Vinci X, a new version of the robot designed to be a little easier on the budget, while still providing most of the flagship model's abilities.

Duke University is developing a cartilage-like material based on hydrogel that allows bioengineers to create bespoke artificial 3D-printed replacement parts for injured knees that are tailored to match the old part both in shape and mechanical properties.

In robotic surgery, doctors control the movement of a mechanical arm through joysticks, knobs and other peripherals. A new exoskeleton system however, turns a doctor's hands into the controls and provides haptic feedback to simulate actually touching a patient's innards.

Minimally invasive surgery often sees large, expensive robots acting as a surgeon's hands inside the patient's body. A new cheaper “needle driver” is designed to precisely mimic the motions of a surgeon’s wrist and translate it to a tiny flexible claw, with no electronic or computerized parts.
