KESKUSTELU

Tämmöisillä käsillä en voi potilaitani hoitaa.

Vaikeaa ei ole luopua rahasta, palkasta, vaan työstä. Olin hyvä siinä kun kädet vielä toimi. Nautin siitä, rakastin sitä. Se oli parasta elämässäni.
Kauan työssäolleelle ihmisellä on paljon tietoa, sitä hiljaistakin. Voi kertoa sellaista, mitä ei voi opettaa missään koulussa, ainoastaan työskentelyn yhteydessä voin kertoa asioista, joita ei ole tieteellisesti todistettu todeksi.
Empiirinen tieto on tärkeää. Mutta. Mutta..

Robotic surgery is the use of robots in performing surgery. Three major advances aided by surgical robots have been remote surgery, minimally invasive surgery, and unmanned surgery [1]. Major potential advantages of robotic surgery are precision and miniaturization. Further advantages are articulation beyond normal manipulation and three-dimensional magnification. Some surgical robots are autonomous, and they are not always under the control of a surgeon. They are only sometimes used as tools to extend the surgical skills of a trained surgeon.

Usually, minimally invasive surgery is performed with the surgeon directly manipulating the surgical instruments. Range of motion at the operation site is limited. At the same time, the endoscope, a small flexible tube with a lighted optical system that is inserted through the tiny incision to view the surgery site, provides only a 2-dimensional image, and surgeons must learn to visualize the procedure by looking at a screen. All of the surgeon’s movements are counterintuitive as though he or she were operating while looking in a mirror. This way of operating is fine for procedures such as knee repair or gallbladder removal that do not call for the complex microsurgical movements needed for heart surgery. The instruments that are used for minimally invasive heart surgery are also longer than instruments used for other types of surgery; therefore, the effect of hand tremors is magnified, making delicate manipulations difficult.

To overcome these limitations with minimally invasive surgery, medical robots were developed. In robot-assisted surgery, instead of directly moving the instruments the surgeon uses a computer console to manipulate the instruments attached to multiple robot arms. Similar to a computer gaming console, the computer translates the surgeon’s movements, which are then carried out on the patient by the robot. Other features of the robotic system include, for example, an integrated tremor filter and the ability for scaling of movements (changing of the ratio between the extent of movements at the master console to the internal movements of the instruments attached to the robot).
