A new robotic-assisted surgical system (Senhance System) has been approved for use in laparoscopic colorectal and gynecological operations.

It helps in the precise control of laparoscopic visualization and endoscopic manipulation.

If a person wants to change the shape of their nose, they do not have to go under the surgeon's scalpel. According to The Daily Mail, Dr. Michael Hill from Occidental College in Los Angeles offers a non-surgical approach. He uses microscopic needles, electric current, and 3D-printed molds to modify living tissues.
This is an inexpensive, minimally invasive procedure performed under local anesthesia. Reshaping the nose takes about five minutes. Cartilage consists of stiff fibers interwoven with each other in a single structure, like spaghetti. Scientists found that tissue with a higher density of electrically charged molecules is stiffer than tissue with a lower "charge density".
If an electric current is passed through cartilage, the tissue becomes more pliable. And at this point, the shape of the nose can be modified (the new form is set by a three-dimensional model). The technology was tested on a rabbit, whose ears normally stand upright. Using the model and electrodes with microneedles, researchers were able to bend one ear without damage. Once the current was removed, the cartilage began to harden in its new shape. Then the model could be removed.
