Dear Dr Upadhyay Robotic surgical systems have greatly led to the advancement of minimally invasive endoscopic surgery. However, current robotic systems do not provide tactile or haptic feedback towards the operating surgeon. Under certain circumstances, particularly using the manipulation of delicate tissues and suture materials, this may prove to be a significant irritation. We haptic feedback, as sensory substitution, facilitates the performance of surgical knot tying and delicate dissection. Visual sensory substitution permits the surgeon to apply more consistent, precise, and greater tensions to fine suture materials without breakage during robot-assisted knot tying along with other dissection. Technological advancements in computer-assisted surgical systems and increasing healthcare demands have expanded the field of non-invasive surgery to new specialties. Robotic surgical systems have many perks over conventional endoscopic surgery, including three-dimensional vision, increased flexibility, tremor filtration, and motion scaling, permitting surgical tasks to become performed in confined spaces. Furthermore, patients and the healthcare industry are aggressively pursuing procedures with smaller incisions, less pain, and shorter recovery times. Computer-assisted robotic surgical systems make total endoscopic cardiac surgery a real possibility. However, current robotic surgical systems are limited by the lack of tactile or haptic feedback important to performing complex, delicate surgical tasks. Clinical successes with robot-assisted non-invasive cardiac surgery have lagged behind those achieved with robot-assisted laparoscopic general surgery due, in large part, towards the lack of feedback. This deficiency with current robotic systems is really a significant handicap in performing the technically more intricate and delicate surgical tasks built into cardiac surgery. For example, suturing a coronary arterial anastomosis with fine polypropylene suture is really a highly dexterous task, where the surgeon typically uses their sense of touch to puncture tissue with a fine needle, pull the suture through, and tie and tighten knots. Observations of experienced and talented cardiac surgeons training with the da Vinci surgical system, fine polypropylene sutures in many cases are broken, and delicate tissues torn, because of the use of excessive forces conventionally attenuated with haptic feedback. The consequences of such surgical errors or delays in cardiac surgery present much greater potentials for irreversible injury, excessive hemorrhage, or even death for the patient.

What is haptic feedback? Haptic technology, or haptics, is a tactile feedback technology which takes advantage of the sense of touch by applying forces, vibrations, or motions to the user.This mechanical stimulation can be used in robotic surgery to assist in the creation of virtual objects in a computer simulation, to control such virtual objects, and to enhance the remote control of machines and devices. It has been described as doing for the sense of touch what computer graphics does for vision. Haptic devices may incorporate tactile sensors that measure forces exerted by the user on the interface. |
