Surgical robot
A surgical robot for performing minimally invasive surgery (e.g. in the eye) is provided. A cannula connection is positioned at a fixed surgical arm part and aligned with a movable surgical arm part movable with respect to the fixed surgical arm part. A surgical instrument can be mounted at the movable part. The surgical instrument can pass through the cannula connection. Reference arm(s) and manipulation arm(s) connect a base element with the fixed surgical arm part. The base element could have a surgical operating table attachment part to movably attach to a surgical operating table and rotating parts movably attached to the surgical operating table attachment part.
1. A surgical robot for performing minimally invasive surgery, comprising:
(a) a base element;
(b) a surgical arm, wherein said surgical arm has a fixed surgical arm part fixed to said base element and a movable surgical arm part which is movable with respect to said fixed surgical arm part, wherein said fixed surgical arm part has a first engagement point and a second engagement point, wherein the fixed surgical arm part has a guide connected to the fixed surgical arm part wherein the guide defines a longitudinal axis and a path along which the movable surgical arm part engages and travels along the guide;
(c) a surgical instrument mounted at said movable arm part;
(d) a reference arm, wherein one end of said reference arm pivotally connects with said first engagement point of said fixed surgical arm part and wherein another end of said reference arm pivotally connects with said base element;
(e) a manipulation arm, wherein one end of said manipulation arm pivotally connects with said second engagement point of said fixed surgical arm part and wherein another end of said manipulation arm pivotally connects with said base element;
(f) a cannula having a conical shape; and
(g) a cannula connector having a conical shape, wherein the cannula connector is affixed to and near one end of said fixed surgical arm part, wherein said conical shape of said cannula connector is adapted to fit and align inside the conical shape of said cannula, and wherein said cannula connector with fitted cannula are aligned with said movable surgical arm part for allowing said mounted surgical instrument to pass through said cannula connector and said cannula.
2. The surgical robot as set forth in claim 1 , wherein said base element is affixed to a surgical operating table.
3. The surgical robot as set h in claim 1 , wherein said base element comprises a surgical operating table attachment part and rotating parts attached to said surgical operating table attachment part.
4. The surgical robot as set forth in claim 1 , wherein said cannula could be positioned within a human or an animal body.
5. The surgical robot as set claim 4 , wherein said human or animal body is an eye.
6. The surgical robot as set forth in claim 1 , wherein said surgical robot is part of a master-slave operating system.
7. The surgical robot as set forth in claim 1 , wherein manipulation control comprises a computer control system configured to control at least a part of the manipulation arm.
