Surgery Without Scars is Possible Now

For a long time, scientists and physicians from around the world are trying to deal with the formation of unsightly scars on the skin of patients after the surgery. However, employees of the University of Pennsylvania have figured out how to make the wounds to heal up without the formation of such defects on the skin. This innovation makes possible to conduct operations, including plastic surgery, without visible consequences.

During experiments, it was found that getting rid of scars can be achieved by converting the cells in the wound, in adipotsidy ie fat cells. In almost all cases, they are lost during the healing period and the appearance of the scar, but a healthy skin has many of them. During post surgery recovery a large number of myofibroblasts can be found at the wound site that contributes to scar tissue.

Scientists have decided to attempt to change the myofibroblasts, by converting them into fat cells, which in turn makes it possible to stop the process of scarring during healing. Specialists get a hold of the regeneration of hair follicles. Certain signals are going through them which carry out the restoration of fat cells in the skin.

Basing on these studies it was concluded that in the wound healing process the hair follicles develop first, which are the basis of transformation of myofibroblasts in the fat cells. In case of absence of follicles it is impossible to obtain such a component, and their presence increases the possibility that the wound will be tightened without a scar. Similar results in the near future will have a huge impact on the development of medicine and allow the patient to forget about unpleasant reminder of the surgery.

Newly Created Surgical Robot Surpassed Human

Individual STAR device (Smart Tissue Autonomous Robot) consists of a robotic arm and an automated instrument for the application of sutures. The robot is also equipped with an infrared 3D-image system that provides a clear path of action, and sensor system – for example, to ensure that the seams will not be too tight or conversely, weak, reports Financial Times.

Experts from the National Children’s Washington tested the STAR health system on pigs, because of the similarity in the arrangement of their internal organs with human.
During the expiriment they conducted an enteroenterostomy (recovery of the digestive tract) – the usual surgical procedure when the tumor is removed.

One of the medical specialists involved in the project Peter Kim said that the results have been amazing, the performance of STAR  was consistently better than did surgeons. According to him, even though the robot is made to work in offline mode, surgen is able to connect to the manipulation at any time.

According to experts, the robot will be in demand in such operations as appendicitis and gallbladder removal. The project is going to be invloved in clinical trial in about three years.
