Robotic surgery is an approach to surgical procedures in which robotic systems are used to assist in surgery. Other names used to refer to this approach include computer-assisted surgery and robot-assisted surgery. This approach was developed as a way of overcoming the limitations that existed in minimally-invasive surgical procedures. It was also developed to improve the ability of surgeons in conducting open surgery. When in need of robotic surgery Houston is the place to go.

Certain advantages are associated with robot-assisted surgical approach which lack in traditional methods. For example, instruments are moved directly in the latter while the former makes use of two major methods to move instruments. In the first method, instruments are moved and controlled using telemanipulators while computer systems are used in the second method.

When telemanipulators are used, manipulators and end-effectors hard-wired into the robotic arms are used to effect the normal movements made by surgeons in relation to the surgical procedure. In effect, the patient is operated by the arms that imitate the movements made by the surgeon. Telemanipulator is a sort of remote manipulator. In computer-controlled systems computers are used to control the robotic arms used in the process. Advancements in technology has made it possible to integrate telemanipulators and computer control.

It is possible to have telemanipulators integrated to be part of computer-controlled systems. However, using computer-controlled system alone offers a certain advantage that does not exist in telemanipulators or a combination of the two methods. The advantage is that computer-controlled systems do not need the surgeon to be physically present in order for it to be done. This has led to the possibility of surgery being done remotely while the surgeon is far away.

This approach is pursued more aggressively because it offers several benefits that cannot be achieved through traditional surgery. Reports from surgeons who have experience with the method state that it offer more control, precision, and flexibility. Surgeons are able to see the site of operation better because of increased flexibility, control, and precision. Operations that would be dangerous and impossible with traditional surgical methods are also done with relative ease.

With robotic surgery, minimally invasive surgery becomes increasingly possible, especially in cardio-thoracic surgeries which have not benefitted from minimally invasive procedures. Minimally invasive procedures offer several advantages including quicker recovery, less pain, less blood loss, smaller, less visible scars, and fewer complications. For instance, infection of the operated site rarely occurs when this approach is used, although it can still happen.

This surgical approach is not suitable for use on every person. As such, it is important to discuss with the doctor about the risks involved and options available before settling for it. In some cases, traditional minimally invasive procedures may prove to be better. However, if it is determined to be better than traditional methods, it should be adopted.

Robot-assisted surgery is adopted variably in the US. The adoption is usually governed by certain factors, which include equipment availability, cultural factors, and physician training. Culturally, institutions maintain a culture regarding the use of robots in their procedure with preference going to traditional methods. In such institutions, conventional less invasive methods are given preference.
