Surgical positioning and support system
A system for performing a medical procedure is provided comprising at least one tool and a tool support for supporting a distal portion of the tool. An operator manipulates a human interface device and produces control signals sent to a controller. The controller manipulates the tool support based on the received control signals.
1. A system for performing a medical procedure comprising: at least one tool comprising a proximal portion and a distal portion with a distal end; a tool support comprising at least one radially extending side lobe constructed and arranged to support the distal portion of the at least one tool, wherein the tool support comprises a highly articulated probe, the probe comprising: an outer sleeve comprising a first plurality of links, the outer sleeve including a proximal link, a distal link, and a plurality of intermediate links between the proximal link and the distal link; and an inner core comprising a second plurality of links, wherein the at least one side lobe extends radially from and is integral with an outermost surface of at least one of the intermediate links of the outer sleeve, wherein the distal link is manipulated by a device controller and articulates independently of the intermediate link of which the at least one side lobe radially extends and further articulates relative to the distal end of the at least one tool extending through the at least one side lobe; the device controller constructed and arranged to create control signals based on operator input and to manipulate a distal end of the probe including the first plurality of links of the outer sleeve of the probe from which the at least one side lobe radially extends; and a controller constructed and arranged to receive the control signals and manipulate the tool support including one of the first plurality of links of the outer sleeve of the probe from which the at least one side lobe radially extends based on the received control signals.
2. The system of claim 1 wherein the highly articulated probe further comprises,
a first cable extending through either said second plurality of links of the inner core or said first plurality of links of the outer sleeve and a plurality of cables running through the other of said plurality of links of the inner core or said plurality of links of the outer sleeve.
3. The system of claim 1 further comprising a feeder assembly constructed and arranged to alternate each of said inner core and outer sleeve between a limp mode and a rigid mode, for advancing and retracting said inner core and outer sleeve, and for steering at least one of said inner core and outer sleeve.
4. The system of claim 1 wherein the tool support comprises a highly articulated probe, wherein the highly articulated probe comprises at least a portion that is controllably rigid and flexible.
5. The system of claim 1 wherein the at least one radially extending side lobe comprises multiple radially extending side lobes each constructed and arranged to support the distal portion of the at least one tool.
6. The system of claim 1 further comprising at least one guide tube constructed and arranged to slidingly receive the at least one tool.
7. The system of claim 6 wherein the tool support comprises a distal portion and the at least one guide tube is attached to said distal portion.
8. The system of claim 7 wherein the at least one guide tube is removably attached to said distal portion.
9. The system of claim 6 further comprising a tool support introducer wherein the at least one guide tube is attached to at a region of the tool support introducer that is proximal to the at least one radially extending side lobe.
10. The system of claim 9 wherein the at least one guide tube is removably attached to the tool support introducer.
11. The system of claim 6 wherein the at least one guide tube comprises at least one of: a flexible portion; a rigid portion; a rigid portion and a flexible portion; or a rotatable coupler.
12. The system of claim 6 wherein the at least one guide tube comprises a funnel shaped opening.
13. The system of claim 6 wherein the at least one guide tube comprises a first guide tube, wherein the at least one tool comprises a first tool, and wherein the system further comprises a second tool and a second guide tube constructed and arranged to slidingly receive the second tool.
14. The system of claim 1 wherein the controller comprises a cable tensioning assembly.
15. The system of claim 1 wherein the at least one tool distal portion comprises a functional element selected from the group consisting of: grasper; cutter; ablater; cauterizer; drug delivery element; radiation source; sensor such as a EKG electrode, pressure sensor or blood sensor; magnet; heating element; cryogenic element; and combinations thereof.
16. The system of claim 1 further comprising a tool holder constructed and arranged to attach to the at least one tool proximal portion.
17. The system of claim 1 further comprising a tool support introducer, wherein the tool support introducer comprises a tube constructed and arranged to slidingly receive the tool support.
18. The system of claim 17 wherein the tool support introducer is constructed and arranged for insertion into the esophagus.
19. The system of claim 1 , wherein in response to a first control signal of the device controller, the distal link articulates independently of the intermediate link of which the at least one side lobe radially extends so that the at least one side lobe is stationary relative to the articulation of the distal link, and wherein in response to a second control signal of the device controller, the distal link and the intermediate link articulate together so that that at least one side lobe articulates with distal link and the intermediate link.
