The world smallest surgeon was developed with the intention of crawling into our body whilst performing surgery. This 1.4 cm beast is sometimes known as the nanobots that has the potential of swimming through the blood. These robots usually take tissue samples and deliver drug for our body through vital human organs such as the ear, eye and lungs. It also has the capability to install other medical devices inside our body.

This is how surgery works with the medical bots in the future. Instead of operating our body with large incisions before performing surgery, the surgeons only need to insert a 1 cm device into our body, particularly for surgery related to stomach and gall bladder. The surgery with the medical robots are proven to help in reducing blood loss, surgery pain and increases the recovery speed. This special device could form a snake by connecting 15 of its similar piece simultaneously. The purpose is for hard-to-reach area in our body. One other speciality of the medical robot is that it could perform stitching from the inner part of our body.

A similar but different device to the medical robot for heart surgery, namely the heart lander has been developed. This device has one purpose, that is to deliver minimal invasive therapy to the surface of our beating heart. It is a special device used particularly for cardiac therapy. In other words, this device will help in reducing necessary damage accessing to our heart. The heart lander is twice the size (3 cm) of the medical robot specified above. The main benefits of using the heart lander is: (1) the price is affordable (2) the motion of our heart beat will not affect the operation of the device (3) it does not breach the lung space, and (4) the device could monitor the specific section of our heart, in the exact location.

The heart lander is monitord by a surgeon through an external monitor (called the X-Ray video machine), controlling the movement with a joystick. Alternatively, the device has enormous sensors that could detect and navigate its own path to that particular spot in our body. Recent research as reported by the Innovation Journal, stated that the first testing was successful with pigs. A roboticist suggests that these medical robots should be available for use by surgeons in the next 5 years.
