The study find that the Vanderbilt collaborators focused on minimally invasive prostate surgery are developing an endoscopic robotic system with two-handed dexterity at a much smaller scale than existing options. A key part of the design telescoping, curved, concentric tubes received U.S. patent protection , therefore the same month the principal investigators secured a $2.1 million R01 grant from the National Institutes of Health to advance the project. In January, Virtuoso Surgical, the team’s Nashville-based company, was highlighted as a “startup to watch” by Med Tech Strategist.
Invasive prostate surgery
Robert Webster III, the Richard A. Schroeder Professor of Mechanical Engineering, and Dr. Duke Herrell; a urologic surgeonat Vanderbilt University Medical Center, seek to enable surgeons to remove the prostate through the urethra and perform delicate reconstructive suturing. “The concentric tube idea lets us make our manipulators an order of magnitude smaller than the surgical robots doctors use today,” Webster said.
“This, along with accessing the prostate from a natural orifice will dramatically reduce surgical invasiveness; helping patients heal faster.” Both Webster and Herrell are core affiliates with the Vanderbilt Institute for Surgery and Engineering. Therefore Collaboration is central to the mission of VISE; but where engineers; surgeons and other experts work side-by-side to develop next-generation instruments that require less tissue and organ disruption and improve surgical outcomes. Giving surgeons two-handed dexterity with small tentacle-like arms at the tip of the endoscope is a significant advancement.
Require less tissue and organ
“Making complex endoscopy easier is a game-changer for multiple surgical and interventional specialties; and most importantly for patients;” said Herrell, a Professor of Urologic Surgery, Biomedical and Mechanical Engineering; and director of Minimally Invasive Urologic Surgery and Robotics at VUMC. Therefore In American men prostate cancer is the second most common cancer behind skin cancer; and the second leading cause of cancer death; behind lung cancer. Up to 1 in 9 U.S. men will develop prostate cancer, and about 1 in 41 will die of it.
In the U.S. alone more than 90,000 prostate surgeries are performed each year; but many as open procedures with an incision 8 to 10 inches long made below the navel. Because In laparoscopic and robot-assisted laparoscopic prostatectomies; surgeons make several small incisions across the belly for insertion of surgical tools and a camera.
The Vanderbilt project would make the surgery much less invasive by introducing tiny surgical instruments through the natural opening provided by the urethra; a process called endoscopic transurethral prostatectomy. The approach would eliminate the need to dissect through healthy tissues from the abdomen into the pelvic area and cause less disruption to the the nerves that control continence and erectile function.
