DETAILED DESCRIPTION OF EMBODIMENTS

Reference will now be made in detail to the present embodiments of the technology, examples of which are illustrated in the accompanying drawings. Similar reference numbers may be used to refer to similar components. However, the description is not intended to limit the present disclosure to particular embodiments, and it should be construed as including various modifications, equivalents, and/or alternatives of the embodiments described herein.

It will be understood that the words “comprising” (and any form of comprising, such as “comprise” and “comprises”), “having” (and any form of having, such as “have” and “has”), “including” (and any form of including, such as “includes” and “include”) or “containing” (and any form of containing, such as “contains” and “contain”) when used herein, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

It will be further understood that, although the terms first, second, third etc. may be used herein to describe various limitations, elements, components, regions, layers and/or sections, these limitations, elements, components, regions, layers and/or sections should not be limited by these terms. These terms are only used to distinguish one limitation, element, component, region, layer or section from another limitation, element, component, region, layer or section. Thus, a first limitation, element, component, region, layer or section discussed below could be termed a second limitation, element, component, region, layer or section without departing from the teachings of the present application.

It will be further understood that when an element is referred to as being “on”, “attached”, “connected” or “coupled” to another element, it can be directly on or above, or connected or coupled to, the other element, or one or more intervening elements can be present. In contrast, when an element is referred to as being “directly on”, “directly attached”, “directly connected” or “directly coupled” to another element, there are no intervening elements present. Other words used to describe the relationship between elements should be interpreted in a like fashion (e.g. “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.).

It will be further understood that when a first element is referred to as being “in”, “on” and/or “within” a second element, the first element can be positioned: within an internal space of the second element, within a portion of the second element (e.g. within a wall of the second element); positioned on an external and/or internal surface of the second element; and combinations of one or more of these.

As used herein, the term “proximate” shall include locations relatively close to, on, in and/or within a referenced component, anatomical location, or other location.

Spatially relative terms, such as “beneath,” “below,” “lower,” “above,” “upper” and the like may be used to describe an element and/or feature's relationship to another element(s) and/or feature(s) as, for example, illustrated in the figures. It will be further understood that the spatially relative terms are intended to encompass different orientations of the device in use and/or operation in addition to the orientation depicted in the figures. For example, if the device in a figure is turned over, elements described as “below” and/or “beneath” other elements or features would then be oriented “above” the other elements or features. The device can be otherwise oriented (e.g. rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

The terms “reduce”, “reducing”, “reduction” and the like, where used herein, are to include a reduction in a quantity, including a reduction to zero. Reducing the likelihood of an occurrence shall include prevention of the occurrence.

The term “and/or” where used herein is to be taken as specific disclosure of each of the two specified features or components with or without the other. For example, “A and/or B” is to be taken as specific disclosure of each of (i) A, (ii) B and (iii) A and B, just as if each is set out individually herein.

In this specification, unless explicitly stated otherwise, “and” can mean “or,” and “or” can mean “and.” For example, if a feature is described as having A, B, or C, the feature can have A, B, and C, or any combination of A, B, and C. Similarly, if a feature is described as having A, B, and C, the feature can have only one or two of A, B, or C.

The expression “configured (or set) to” used in the present disclosure may be used interchangeably with, for example, the expressions “suitable for”, “having the capacity to”, “designed to”, “adapted to”, “made to” and “capable of” according to a situation. The expression “configured (or set) to” does not mean only “specifically designed to” in hardware. Alternatively, in some situations, the expression “a device configured to” may mean that the device “can” operate together with another device or component.

It is appreciated that certain features of the invention, which are, for clarity, described in the context of separate embodiments, may also be provided in combination in a single embodiment. Conversely, various features of the invention which are, for brevity, described in the context of a single embodiment, may also be provided separately or in any suitable sub-combination. For example, it will be appreciated that all features set out in any of the claims (whether independent or dependent) can be combined in any given way.

It is to be understood that at least some of the figures and descriptions of the invention have been simplified to focus on elements that are relevant for a clear understanding of the invention, while eliminating, for purposes of clarity, other elements that those of ordinary skill in the art will appreciate may also comprise a portion of the invention. However, because such elements are well known in the art, and because they do not necessarily facilitate a better understanding of the invention, a description of such elements is not provided herein.

Terms defined in the present disclosure are only used for describing specific embodiments of the present disclosure and are not intended to limit the scope of the present disclosure. Terms provided in singular forms are intended to include plural forms as well, unless the context clearly indicates otherwise. All of the terms used herein, including technical or scientific terms, have the same meanings as those generally understood by an ordinary person skilled in the related art, unless otherwise defined herein. Terms defined in a generally used dictionary should be interpreted as having meanings that are the same as or similar to the contextual meanings of the relevant technology and should not be interpreted as having ideal or exaggerated meanings, unless expressly so defined herein. In some cases, terms defined in the present disclosure should not be interpreted to exclude the embodiments of the present disclosure.

Processor 700

Processing unit 700 can comprise one or more controllers and/or processors, located throughout system 10. For example, processor 700 can comprise a computer or other processing device, and/or can comprise one or more controllers or modules of system 10 (e.g. module 127 of feeder 100, processor 504 of stand 500, and/or processor 604 of user interface 600). Processing unit 700 can comprise one or more algorithms for processing data and/or commanding one or more components of system 10 to perform one or more operations. Processing unit 700 can comprise one or more controllers for controlling components of system 10. Processing unit 700 can comprise a stand controller 750, for operational control of stand 500. Processing unit 700 can comprise a camera controller, for operational control of camera assembly 800. Camera controller 780 can be operably attached to a video processor 781 for processing image data captured by camera 820. Video processor 781 can provide processed image data to a display 785, for display to a user. Processing unit 700 can comprise a haptic controller 760, operably attached to input devices 610a,b of console 600, for example via processor 604. Haptic controller 760 can be operably attached to a motion processor 762, which is operably attached to a probe controller 763, and one or more tool controllers 764. Haptic controller 760 can receive robotic input data (e.g. via a kinematic input device) from input devices 610a,b, and/or provide haptic feedback commands to input devices 610a,b.

Tool controllers 764 can provide commands to one or more motors of system 10, for example one or more motors of a tool drive 200 to at least advance, retract, steer, and/or otherwise control the position and/or articulation of an attached tool 400.

Processor 700 can be of similar construction and arrangement to the similar device described in applicant's co-pending application U.S. Provisional Application No. 62/614,235, filed Jan. 5, 2018, the content of which is incorporated herein by reference in its entirety.

Referring additionally to FIGS. 1A-C, graphic demonstrations of a robotic probe 300 are illustrated, consistent with the present inventive concepts. Articulating probe 300 comprises essentially two concentric mechanisms, an outer mechanism and an inner mechanism, each of which can be viewed as a steerable mechanism. Each of the components of probe 300 can comprise one or more sealing elements, such as to support an insufflation procedure. FIGS. 1A-C show the concept of how different embodiments of robotic probe 300 operate. Referring to FIG. 1A, the inner mechanism can be referred to as a first mechanism or inner probe 310. The outer mechanism can be referred to as a second mechanism or outer probe 350. Each mechanism can alternate between rigid and limp states. In the rigid mode or state, the mechanism is just that—rigid. In the limp mode or state, the mechanism is highly flexible and thus either assumes the shape of its surroundings or can be re-shaped. It should be noted that the term “limp” as used herein does not necessarily denote a structure that passively assumes a particular configuration dependent upon gravity and the shape of its environment; rather, the “limp” structures described in this application are capable of assuming positions and configurations that are desired by the operator of the device, and therefore are articulated and controlled rather than flaccid and passive.

In some embodiments, one mechanism starts limp and the other starts rigid. For the sake of explanation, assume outer probe 350 is rigid and inner probe 310 is limp, as seen in step 1 in FIG. 1A. Now, inner probe 310 is both pushed forward by feeder 100, and a distal-most inner link 315D is steered, as seen in step 2 in FIG. 1A. Now, inner probe 310 is made rigid and outer probe 350 is made limp. Outer probe 350 is then pushed forward until a distal-most outer link 355D catches up to the distal-most inner link 315D (e.g. outer probe 350 is coextensive with inner probe 310), as seen in step 3 in FIG. 1A. Now, outer probe 350 is made rigid, inner probe 310 limp, and the procedure then repeats. One variation of this approach is to have outer probe 350 be steerable as well. The operation of such a device is illustrated in FIG. 1B. In FIG. 1B it is seen that each mechanism is capable of catching up to the other and then advancing one link beyond. According to one embodiment, outer probe 350 is steerable and inner probe 310 is not. The operation of such a device is shown in FIG. 1C.

In medical applications, operation, procedures, and so on, once robotic probe 300 arrives at a desired location, the operator, such as a surgeon, can slide one or more tools through one or more working channels of outer probe 350, inner probe 310, or one or more working channels formed between outer probe 350 and inner probe 310, such as to perform various diagnostic and/or therapeutic procedures. In some embodiments, the channel is referred to as a working channel that can, for example, extend between first recesses formed in a system of outer links and second recesses formed in a system of inner links. Working channels may be included on the periphery of robotic probe 300, such as working channels comprising one or more radial projections extending from outer probe 350, these projections including one or more holes sized to slidingly receive one or more tools. As described with reference to other embodiments, working channels may be positioned on other locations extending from, on, in, and/or within robotic probe 300.

Inner probe 310 and/or outer probe 350 are steerable and inner probe 310 and outer probe 350 can each be made both rigid and limp, allowing robotic probe 300 to drive anywhere in three-dimensions while being self-supporting. Articulating probe 300 can “remember” each of its previous configurations and for this reason, robotic probe 300 can retract from and/or retrace to anywhere in a three-dimensional volume such as the intracavity spaces in the body of a patient such as a human patient.

Inner probe 310 and outer probe 350 each include a series of links, i.e. inner links 315 and outer links 355 respectively, that articulate relative to each other. In some embodiments, outer links 355 are used to steer and lock robotic probe 300, while inner links 315 are used to lock robotic probe 300. In a “follow the leader” fashion, while inner links 315 are locked, outer links 355 are advanced beyond the distal-most inner link 315D. Outer links 355 are steered into position by the system steering cables, and then locked by locking the steering cables. The cable of inner links 315 is then released and inner links 315 are advanced to follow outer links 355. The procedure progresses in this manner until a desired position and orientation are achieved. The combined inner links 315 and outer links 355 may include working channels for temporary or permanent insertion of tools at the surgery site. In some embodiments, the tools can advance with the links during positioning of robotic probe 300. In some embodiments, the tools can be inserted through the links following positioning of robotic probe 300.

One or more outer links 355 can be advanced beyond the distal-most inner link 315D prior to the initiation of an operator controlled steering maneuver, such that the quantity extending beyond the distal-most inner link 315D will collectively articulate based on steering commands. Multiple link steering can be used to reduce procedure time, such as when the specificity of single link steering is not required. In some embodiments, between 2 and 20 outer links can be selected for simultaneous steering, such as between 2 and 10 outer links or between 2 and 7 outer links. The number of links used to steer corresponds to achievable steering paths, with smaller numbers enabling more specificity of curvature of robotic probe 300. In some embodiments, an operator can select the number of links used for steering (e.g. to select between 1 and 10 links to be advanced prior to each steering maneuver).
