Created in the 1970s, laparoscopy involves making small incisions on a person’s abdominal wall to insert an endoscope, a flexible tube equipped with a light source and a small camera.

It is thus possible to observe the digestive (like the liver or the colon), genital (like the uterus or the ovaries) or urinary organs. It thus makes it possible to diagnose various diseases, and sometimes even to carry out surgeries without opening the abdomen.

The STAR robot (for Smart Tissue Autonomous Robot) even performed an intestinal anastomosis perfectly, which involves joining two parts of the digestive tract.

This procedure requires repetitive movements of great precision. Connecting the two ends of an intestine is arguably the most difficult step in gastrointestinal surgery, as it requires the surgeon to very precisely suture. The slightest tremor of the hand or a misplaced stitch can lead to a leak which could have catastrophic complications for the patient.specifies the American university in a press release.

Operating on soft tissue is particularly difficult for robots due to the unpredictability of the situation, which forces them to adapt quickly to deal with unexpected obstacles.adds Professor Krieger. The STAR has a new control system that allows the surgical plan to be adjusted in real time, just as a human surgeon would.

The STAR is the first robotic system capable of planning, adapting and executing a surgical plan in soft tissue with minimal human interventionsays Hamed Saeidi, first author of the work published in the journal Science RoboticsHave (New window)Have (in English).
