1. A surgical robot for performing a medical procedure, comprising:
- (a) an instrument manipulator comprising a manipulator front end, wherein said manipulator front end comprises a base body defining a longitudinal axis with a proximal end and a distal end;
(b) a container movably connected to said base body near said proximal end of said longitudinal axis, wherein said container comprises an instrument holder for holding a surgical instrument, wherein said instrument holder has a through-hole for holding said surgical instrument, wherein said through-hole has a proximal end and a distal end in the direction of said longitudinal axis, and wherein at least part of said surgical instrument when held in said instrument holder extends passed said distal end of said through-hole and towards said distal end of said base body;
(c) an instrument receiver for receiving said surgical instrument from below said distal end of said respective through-hole of said instrument holder, wherein said instrument receiver comprises a clamping mechanism, wherein said clamping mechanism can clamp said surgical instrument when said clamping mechanism is changing from a passive no-clamping state to an active clamping state;
(d) a cannula connector with a proximal end and a distal end parallel with said longitudinal axis, said cannula connector is a rigid connector mounted to said distal end of said base body, said surgical instrument to go through said cannula connector, wherein said cannula connector remains distal to said instrument receiver, wherein said cannula connector can be fixated onto a cannula to establish a connection between said base body and said cannula via said cannula connector, wherein said cannula is also parallel with said longitudinal axis; and
(e) a linear guide to actively guide said instrument receiver towards said instrument holder where said instrument receiver can actively clamp said surgical instrument through said clamping mechanism, wherein said linear guide can actively guide said instrument receiver with said clamped surgical instrument in longitudinal direction towards said cannula connector, and wherein the translation of said instrument receiver towards said cannula connector while said surgical instrument is clamped by said clamping mechanism of said instrument receiver causes said surgical instrument to be released from said instrument holder.
