Definitions
- Embodiments relate generally to the field of robotics and more particularly, to three dimensional, flexible, steerable robotic devices.
- Robert Sturges' U.S. Pat. No. 5,759,151 discloses a flexible, steerable device for conducting exploratory procedures.
- the device includes at least one spine, each having stiffening means for selectively rendering the spine rigid and flexible along its length.
- a flexible sheath surrounds the spine and is axially slidably moveable relative to the spine so that the sheath will follow and conform to the shape of a spine in the rigid state and resist further flexure when the spine is in a relaxed state.
- a steerable distal tip is provided on the distal end of the device.
- Controls for the distal tip are mounted on the proximal end of the device. Mechanisms are provided on the distal end of the device for selectively activating and deactivating the stiffening means of the spine.
- An instrument conduit may be mounted on the sheath.
- U.S. Pat. No. 6,610,007 to Amir Belson, et. al., incorporated herein by reference in its entirety, discloses a steerable endoscope having an elongated body with a selectively steerable distal portion and an automatically controlled proximal portion.
- the endoscope body is inserted into a patient and the selectively steerable distal portion is used to select a desired path within the patient's body.
- an electronic motion controller operates the automatically controlled proximal portion to assume the selected curve of the selectively steerable distal portion.
- Another desired path is selected with the selectively steerable distal portion and the endoscope body is advanced again.
- the selected curves propagate proximally along the endoscope body, and when the endoscope body is withdrawn proximally, the selected curves propagate distally along the endoscope body. This creates a serpentine motion in the endoscope body allowing it to negotiate tortuous curves along a desired path through or around and between organs within the body.

Abstract
Description
- This application is a continuation application of U.S. application Ser. No. 13/812,324, filed Sep. 17, 2013, which is a 371 application of PCT/US2011/044811, filed Jul. 21, 2011, which claims the benefit of U.S. Provisional Application Ser. No. 61/368,257 filed Jul. 28, 2010, which is incorporated herein by reference, in its entirety.
- Embodiments relate generally to the field of robotics and more particularly, to three dimensional, flexible, steerable robotic devices.
- There are numerous types of steerable multi-linked probes, and such devices are utilized in a variety of different applications. Robert Sturges' U.S. Pat. No. 5,759,151, which is hereby incorporated by reference in its entirety, discloses a flexible, steerable device for conducting exploratory procedures. The device includes at least one spine, each having stiffening means for selectively rendering the spine rigid and flexible along its length. A flexible sheath surrounds the spine and is axially slidably moveable relative to the spine so that the sheath will follow and conform to the shape of a spine in the rigid state and resist further flexure when the spine is in a relaxed state. A steerable distal tip is provided on the distal end of the device. Controls for the distal tip are mounted on the proximal end of the device. Mechanisms are provided on the distal end of the device for selectively activating and deactivating the stiffening means of the spine. An instrument conduit may be mounted on the sheath. Howie Choset's U.S. patent application Ser. No. 11/630,279, which is hereby incorporated by reference in its entirety, discloses a feeder mechanism for advancing and retracting both an inner core and an outer sleeve, as well as selectively applying tension to control cables used for steering and causing either the inner core or outer sleeve to transition between a rigid state and a limp state.
- U.S. Pat. No. 6,610,007 to Amir Belson, et. al., incorporated herein by reference in its entirety, discloses a steerable endoscope having an elongated body with a selectively steerable distal portion and an automatically controlled proximal portion. The endoscope body is inserted into a patient and the selectively steerable distal portion is used to select a desired path within the patient's body. When the endoscope body is advanced, an electronic motion controller operates the automatically controlled proximal portion to assume the selected curve of the selectively steerable distal portion. Another desired path is selected with the selectively steerable distal portion and the endoscope body is advanced again. As the endoscope body is further advanced, the selected curves propagate proximally along the endoscope body, and when the endoscope body is withdrawn proximally, the selected curves propagate distally along the endoscope body. This creates a serpentine motion in the endoscope body allowing it to negotiate tortuous curves along a desired path through or around and between organs within the body.
- For medical use and other critical applications, it is extremely important that each device not only perform as intended and within known specifications, but have repeatable performance and otherwise consistent operation from use to use. For these and other reasons, there is a need for systems, devices and methods which provide integrated calibration routines and mechanisms.

Introducer 300 includes twoguide tubes guide tube Guide tubes rotatable couplers Couplers Coupler 400 a includes an actuator, lever 401 a. Movement oflever 401 a in one direction, for example, a downward direction relative to a user, rotatescam sleeve 402 a to apply a force that linearly displacescam 403 a which closesgap 405 a, lockingball 406 a in place, thus placingguide tube 339 a in a locked state. In this locked state, movement ofguide tube 339 a is prevented, including when a force is applied, such as a when a force is applied during manipulation of a tool whose shaft has been inserted throughguide tube 339 a. - Conversely, movement of
lever 401 a in the opposite direction, i.e. an upward direction relative to the user, rotatescam sleeve 402 a to release the force applied tocam 403 a allowingcam 403 a to linearly displace in the opposite direction, increasinggap 405 a. The increase ingap 405 a releases the force applied toball 406 a, placingguide tube 339 a in an unlocked state. In this unlocked state, guidetube 339 a remains frictionally engaged withcoupler 400 a, such thatguide tube 339 a is gravitationally supported but free to move (e.g. by the hand of an operator) relative toball 406 a. Additionally,coupler 400 a may include a screw, includingscrew head 407 a, that is fixed in place, such as via an adhesive, to prevent loosening.Screw head 407 a can provide a bearing surface forcam sleeve 402 a.Coupler 400 a includesinsert 404 a that provides a surface against whichcam 403 a translates. -
Coupler 400 b components are similar to that ofcoupler 400 a, for example,coupler 400 b includeslever 401 b,gap 405 b, andball 406 b. Additionally, the functionality of thecoupler 400 b and its components are typically the same or similar to that ofcoupler 400 a. - While the preferred embodiments of the devices and methods have been described in reference to the environment in which they were developed, they are merely illustrative of the principles of the present inventive concepts. Modification or combinations of the above-described assemblies, other embodiments, configurations, and methods for carrying out the inventive concepts, and variations of aspects of the inventive concepts that are obvious to those of skill in the art are intended to be within the scope of the claims. In addition, where this application has listed the steps of a method or procedure in a specific order, it may be possible, or even expedient in certain circumstances, to change the order in which some steps are performed, and it is intended that the particular steps of the method or procedure claim set forth herebelow not be construed as being order-specific unless such order specificity is expressly stated in the claim.
