Robotic surgery

Robotic surgery or robot-assisted surgery is any type of surgical procedure that is performed with the use of robotic systems. Robotically assisted surgery was developed with the primary goal of overcoming the limitations of pre-existing minimally invasive surgical procedures, alongside enhancing the capabilities (for example, increasing their work precision) of surgeons performing open surgeries.

In robotically assisted minimally-invasive surgery, the surgeon uses either a remote manipulator or a computer control system to perform dissection, hemostasis, and resection.

A telemanipulator (e.g. the da Vinci Surgical System) is a system of remotely controlled manipulators that enables a surgeon to perform the surgery in real-time under stereoscopic vision from a control console separate from the operating table. In this case, the surgical robot is docked next to the patient, while the robotic arms carry out endoscopy-like maneuvers via end-effectors inserted through specially designed trocars. A surgical assistant and a scrub nurse are often still needed scrubbed at the tableside to help switch effector instruments or provide additional suction or temporary tissue retraction using endoscopic grasping instruments.

In computer-controlled systems, the surgeon uses a computer system to relay control data and direct the robotic arms and their end-effectors, even though these systems still possess the ability to use telemanipulators for their input. One of the primary advantages of using the computerized method is that it does not require the surgeon to be physically present on campus to perform the procedure, leading to the possibility for remote surgery and even AI-assisted or automated procedures.

The capital barrier to robotic surgery has decreased as lower-cost, modular systems like Medtronic's Hugo and CMR Surgical's Versius enter the market as alternative offerings to existing platforms.
