FIG. 1 is a perspective view of a robotic introducer system 10, in accordance with embodiments of the present inventive concepts. The robotic introducer system 10 can be constructed and arranged to perform a medical procedure, such as a transoral robotic surgery procedure. The system 10 may include one or more features of a surgical positioning and support system, for example, described in PCT Application serial number PCT/US2011/044811, filed Jul. 21, 2011, PCT Application serial number PCT/US2012/32279, filed Apr. 5, 2012, and PCT Application No. PCT/US2013/054326, filed Aug. 9, 2013, the contents of each of which are herein incorporated by reference in their entirety.

The robotic introducer system 10 is constructed and arranged to position one or more tools (not shown) for performing a medical procedure on a patient, for example, a transoral robotic surgery procedure or the like, or other surgical procedure that includes inserting one or more tools into a cavity of the patient, or a region of the patient formed by an incision or related opening. A surgical procedure can include one or more transoral procedures, including but not limited to resections at or near the base of a tongue, tonsils, a base of a skull, hypopharynx, larynx, trachea, esophagus and within the stomach and small intestine. Other medical procedures can include but not be limited to single or multiple transaxilla procedures, such as a laryngectomy, single or multiple thoracoscopic procedures, such as a mediastinal nodal dissection, single or multiple pericardial procedures, for example, related to measuring and treating arrhythmias, single or multiple laparoscopic procedures, such as revision of bariatric lap-band procedures, single or multiple transgastric or transenteric procedures, such as a cholecystectomy or splenectomy, and/or single or multiple transanal or transvaginal procedures, such as a hysterectomy, oophorectomy, cystectomy and colectomy.

The robotic introducer system 10 includes a first assembly 12, a second assembly 14, and a third assembly 16. The first assembly 12 is constructed and arranged to be used a plurality of times in one or more medical procedures. The second assembly 14 is constructed and arranged to be used fewer times than the first assembly 12. The third assembly 16 is constructed and arranged to be used in one or more medical procedures, but fewer times than the second assembly 14. In some embodiments, the third assembly 16 is constructed and arranged for a single use. In some embodiments, the third assembly 16 is constructed and arranged for multiple uses, but fewer uses than the second assembly 14.

The term “use” can refer to a use of the first, second, and/or third assembly in one or more procedures for a particular patient. For example, the third assembly 16 can be used to perform one or more medical procedures on one patient, removed from the system 10, and replaced with a different third assembly 16 that is used to perform one or more medical procedures on a different patient. In another example, the third assembly 16 can be used to perform a procedure on one patient, removed from the system 10, and replaced with a different third assembly 16 that is used to perform a different procedure on the same patient.

The first, second, and/or third assemblies 12, 14, 16 can include a processor and a memory for storing program code for performing one or more features and functions described herein. For example, program code for performing a camera calibration such as a gamma correction, or for counting the number of clinical uses of an assembly, can be stored in the memory.

The second and third assemblies 14, 16 are typically sanitized (e.g. cleaned, disinfected and/or sterilized) for each use. Unlike the second and third assemblies 14, 16, in some embodiments, the first assembly 12 is not positioned in an environment that requires sterilization after each use, for example, sterilization that would be required between medical procedures performed on different patients. In other embodiments, one or more portions of first assembly 12 are covered by one or more sterile barriers, such as sterile drape positioned between first assembly 12 and third assembly 16. The second assembly 14 can be sanitized (e.g. cleaned, disinfected and/or sterilized) between uses. In some embodiments, the third assembly 16 is sanitized, typically sterilized, for a single use, and is removed from the first and third assemblies 12, 16, and disposed of, after its single use.

The first assembly 12 includes a base unit 200 comprising a cable control assembly 220 that controls a movement of an articulating probe assembly 120 of the third assembly 16, described below. The base unit 200 can include other elements similar to those described in PCT Application No. PCT/US2012/070924, filed Dec. 20, 2012, the contents of which are incorporated herein by reference in their entirety.

The first assembly 12 includes a base stand 212, or related brace, which attaches the base unit 200 to a floor, a patient operating table, or other supporting object. A handle 210 can extend from the base unit 200 that permits an operator to move the robotic introducer system 10 relative to the supporting structure to which the base stand 212 is coupled, for example, a floor, a patient operating table, etc., before or during a medical procedure, or between different procedures.

The first assembly 12 comprises a console system 150. The console system 150 includes a monitor and a human interface device (HID) (not shown). The monitor may be configured to display images and/or sensor readings from tools or related devices, e.g., cameras, probes, sensors, which are coupled to or otherwise provided with the articulating probe assembly 120, the second assembly 14 and/or one or more other components of the system 10. The console system 150 may further include an input device, such as a keyboard, touch screen, touch pad and/or pointing device, for communicating with elements of the robotic introducer system 10, such as the articulating probe assembly 120.

An operator, such as a surgeon or other medical professional, may control the robotic introducer system 10 via the HID to manipulate or otherwise control the functions and movement of the articulating probe assembly 120, for example, steer, advance, retract or otherwise control the functions and movement of articulating probe assembly 120. The HID may include a hand-operated control device, such as a joystick.

The first assembly 12 can be coupled to one or more different third assemblies 16, for example, over the lifetime of the first assembly. Features of an exemplary third assembly are described at PCT Application No. PCT/US2012/070924, filed Dec. 20, 2012, the contents of which are incorporated by reference above.

The third assembly 16 can be coupled between the first assembly 12 and the second assembly 14, such as a coupling the directions shown by the arrows. The third assembly 16 comprises a probe feeder 110 that is removably coupled between the first assembly 12 and the second assembly 14. The articulating probe assembly 120 of the third assembly 16 is removably coupled to the second assembly 14. The probe feeder 110 can include a carriage, guide rails, cables, gears, and/or other mechanical devices that communicate with the cable control assembly 220 of the base unit 200 of the first assembly 12 to control a movement of the articulating probe assembly 120, and/or one or more tools in communication with the articulating probe assembly 120. For example, the base unit 200 can include motor driven wheels, which engage and drive bobbins, gears, or the like, which in turn can advance and retract a carriage of the probe feeder 110.

The articulating probe assembly 120 can include a plurality of links that are constructed and arranged to facilitate a manipulation of the probe assembly 120, which in turn can guide one or more surgical tools during a medical procedure. The links can be constructed and arranged to form at least one multi-link inner probe (not shown) and a multi-link outer probe, similar to a probe assembly described in PCT Application No. PCT/US2012/032279, filed Apr. 5, 2012, the content of which is incorporated herein by reference above. The inner probe can include a plurality of inner links and the outer probe can include a plurality of outer links. The inner probe and the outer probe can communicate with each other by a plurality of steering cables (not shown), which are steerable by the cable control assembly 220, for example, which can advance or retract the links with respect to one another during manipulation of the articulating probe assembly 120. The steering cables can be used to releasingly tighten to lock or stiffen either or both of the plurality of inner links or the plurality of outer links. Accordingly, the inner probe and the outer probe can be configured in one of a limp mode and a rigid mode so as to facilitate the manipulation of the articulating probe assembly 120. For example, the inner and outer links may be configured in one of the limp mode and the rigid mode via one or more steering cables of the articulating probe assembly 120.

The articulating probe assembly 120 includes a connecting link 115 at a distal end of the outer links, also referred to as a distal link, which is removably coupled to a portion of the second assembly 14, as described in FIG. 2 herein. The connecting link 115 can include one or more working channels 117 for transferring electrical signals and/or tools to the second assembly 14. The working channels 117 may extend through some or all of the articulating probe assembly 120, for example, in a channel between the inner and outer links, from a proximal end to a distal end of the articulating probe assembly 120. The working channels 117 can be aligned with working channels extending through a distal link extension assembly of the second assembly 14, as described herein.

The second assembly 14 includes an introduction device 250 constructed and arranged to slidingly receive the articulating probe assembly 120. The second assembly 14 is also constructed and arranged to position and/or provide support to one or more tools (not shown) for performing a medical procedure on a patient. The second assembly 14 can be coupled over its lifetime to at least two different third assemblies 16, for example, where each third assembly 16 is constructed and arranged to perform a single use, while the second assembly 14 is constructed and arranged for reuse. In an embodiment, the second assembly 14 includes a distal link extension assembly 202 for coupling with the connecting link 115 at the distal end of the articulating probe assembly 120 of the third assembly 16.

FIG. 2 is a perspective view of the second assembly 14, in accordance with an embodiment. As described in FIG. 1, the second assembly 14 comprises an introduction device 250. The second assembly 14 also comprises a first tool guide tube 260a, and a second tool guide tube 260b, also referred to as tool supports. Although two tool guide tubes 260a, 260b (generally, 260) are shown, the second assembly 14 can be constructed and arranged to include more than two tool guide tubes 260 or, alternatively, can include a single guide tube 260. Each tool guide tube 260 is constructed and arranged to slidingly receive a tool or other elongate object used in a medical procedure.

The first tool guide tube 260a can include an outer guide tube 262a and an inner guide tube 263a that is slidingly received by the outer guide tube 262a. The second tool guide tube 260b can include an outer guide tube 262b and an inner guide tube 263b that is slidingly received by the outer guide tube 262b. Accordingly, each of the tool guide tubes 260 can have an inner guide tube 263a, b (generally, 263) that movably extends from the outer guide tube 262a, b (generally, 262), for example, in a telescoping configuration.

At least a portion of each inner guide tube 263 is flexible. To achieve this, an inner guide tube 263 can include one or more hinged sections. At least a portion of each outer guide tube 262 is rigid, with limited or no flexibility. The inner guide tubes 263 can be formed of plastic or related material. Materials can include but are not limited to fluoropolymers (e.g., polytetrafluoroethylene), fluorinated ethylene propylene, polyether block amide, high density polyethylene, low density polyethylene and/or nickel titanium alloy. The inner guide tubes 263 can comprise laser cut tubes, e.g. polymer or metal tubes with cuts placed to provide flexibility, and/or coils or braids of plastic or metal. In some embodiments, an inner guide tube 263 comprises a polytetrafluoroethylene liner. In some embodiments, an inner guide tube 263 comprises a stainless steel coil. In some embodiments, an inner guide tube 263 comprises a coil covered by a polyether block amide. In some embodiments, an inner guide tube 263 comprises varying stiffness along its length.

The second assembly 14 can include a base 285. The base 285 can comprise a collar that surrounds at least a portion of the introduction device 250, and is fixedly attached to the surface of the introduction device 250. The collar can extend in a lateral direction relative to a direction of extension of the introduction device 250. The collar has first and second openings. The outer guide tubes 262 of the tool guide tube 260 can be coupled to one side of the first and second openings, and the inner guide tubes 263 can extend from the first and second outer guide tubes 262, respectively, at a second side of the first and second openings. The first tool guide tube 260a and the second tool guide tube 260b are coupled to the base 285 to maintain a relative position between the first tool guide tube 260a and the second tool guide tube 260b and/or maintain a fixed orientation between the first tool guide tube 260a and the second tool guide tube 260b. The base 285 can also comprise an opening for receiving, and holding in place against, the introduction device 250 and/or an articulating probe, such as probe assembly 120 of system 10, advanced therethrough.

One or more tool guide tubes 260 can rotatably engage the base 285. The tool guide tube 260 can be coupled to the base 285 by a gimbal or other pivoted or ball and joint mechanism (not shown), permitting the tool guide tube 260 to rotate relative to the base 285, for example, allowing for three degrees of freedom between tool guide tube 260 and base 285, which can include two-dimensional (X-Y) movement plus rotation.

In other embodiments, the first and second tool guide tubes 260a, 260b are fixedly coupled to a surface of the introduction device 250 instead of a base, for example, via welding points, adhesives, or other bonding mechanisms. The connection at the introduction device 250 maintains a fixed distance and/or a fixed orientation between the first tool guide tube 260a and the second tool guide tube 260b. In some embodiments, the first and second tool guide tubes 260a and 260b can be rotatably attached to each other and/or a base for maintaining a fixed distance but not a fixed orientation. The first tool guide tube 260a and the second tool guide tube 260b can be fixed in position relative to each other. Accordingly, positions of the first and second tool guide tubes 260a, 260b can be maintained during an operation of the robotic introducer system 10.

The second assembly 14 can include a guide tube support 280 coupled to the first tool guide tube 260a and the second tool guide tube 260b. The guide tube support 280 is constructed and arranged to maintain a relative position between the first tool guide tube 260a and the second tool guide tube 260b. In some embodiments, guide tube support 280 is constructed and arranged to maintain a relative orientation between the first tool guide tube 260a and the second tool guide tube 260b. In an embodiment, the guide tube support 280 includes a dogbone connector, for example, described with reference to PCT Application No. PCT/US2013/054326, filed Aug. 9, 2013, incorporated by reference above. The guide tube support 280 can be removably attached to the tool guide tubes 260a, 260b. Accordingly, in some embodiments, the guide tube support 280 is used with two or more different second assemblies 14, depending on the medical procedure. For example, in a first medical procedure, the guide tube support 280 is attached to a second assembly 14. After the first medical procedure, the guide tube support 280 can be sanitized, and used in a second medical procedure, where the guide tube support 280 is attached to a different second assembly 14.

The guide tube support 280 can comprise a rigid structure. Alternatively, the guide tube support 280 can comprise a malleable or flexible structure. The guide tube support 280 can comprise at least a portion that is flexible. The guide tube support 280 can comprise an operator shapeable structure. The guide tube support 280 can comprise two segments connected by a hinge, such as a butt hinge, a butterfly hinge, a barrel hinge or a hinge comprising a flexible portion positioned between two rigid portions. The guide tube support 280 can comprise a telescopically adjustable structure, such as to allow separation of tool supports 260a and 260b. The guide tube support 280 can comprise two segments connected by a rotatable connector, such as a universal joint.

The guide tube support 280 can be constructed and arranged to be shaped, molded, or the like, such as after the application of heat. The guide tube support 280 can be constructed and arranged to be attachable to at least one of the first tool guide tube 260a or the second tool guide tube 260b. The guide tube support 280 can be constructed and arranged to be detachable to at least one of the first tool guide tube 260a or the second tool guide tube 260b.

The guide tube support 280 comprises a first opening 264a and a second opening 264b (generally 264), each constructed and arranged to operably engage an outer guide tube 262a, 262b of the first and second tool supports 260a, 260b, respectively. The first opening 264a and the second opening 264b can be constructed and arranged to position the first tool guide tube 260a and the second tool guide tube 260b in a non-parallel configuration. At least one of the first opening 264a or the second opening 264b can comprise a funnel-shaped opening, for example, for receiving an outer guide tube 262. In this manner, an uninterrupted tool path can extend from an opening 264 at the guide tube support 280 through a tool guide tube 260 to a tool exit at a side port 237 of the distal link extension assembly.

In embodiments where a tool guide tube 260 is slidably adjustable, thus allowing for a shortening of a portion of the guide tube 260 that attaches to the guide tube support 280, the guide tube support 280 may require adjustability of the distance between connector openings. Depending on the desired relative orientation of one guide tube 260 to the other, parallel or angled, then the adjustability in the guide tube support 280 for the distance between openings can occur along a straight or curved path. The tool guide tube 260 can be locked in a fixed position relative to the base 285. The second assembly 14 can include a locking mechanism (not shown) to lock the at least one tool guide tube 260 in the fixed position. The locking mechanism may be constructed to secure a position of the tool guide tubes 260 with respect to the base 285, thus preventing the tool guide tubes 260 from sliding or otherwise moving axially during movement of the tools by one or more operators.

An outer guide tube 262 can have a funnel-shaped proximal end (not shown). The inner guide tube 263 can likewise have a funnel shaped proximal end (not shown). Either or both funnels can be configured to readily and atraumatically introduce tools to the tool guide tube 260. A funnel shaped proximal end of each tool guide tube 260 can be positioned about an opening 264 in a guide tube support 280. In this manner, an uninterrupted tool path can extend from an opening 264 through a tool guide tube 260 to a tool exit at a side port 237 of second assembly 14.

The introduction device 250 can be constructed and arranged to slidingly receive the articulating probe assembly 120 of the third assembly 16 of FIG. 1, and support, stabilize, and/or guide the articulating probe assembly 120 to a region of interest. The region of interest may be a lumen of a body of a patient, such as a cavity at the patient's head, e.g., a nose or mouth, or an opening formed by an incision. In clinical applications, typical regions of interest can include but not limited to the esophagus or other locations within the gastrointestinal tract, the pericardial space, the peritoneal space, and combinations thereof. The region of interest may alternatively be a mechanical device, a building, or another open or closed environment in which the articulating probe assembly 120 can be used.

In an embodiment, the second assembly 14 includes a distal link extension assembly 202 for coupling with the connecting link 115 at the distal end of the articulating probe assembly 120 of the third assembly 16.

The distal link extension assembly 202 includes a distal link body 302, a camera assembly 304, a lighting assembly 306, and a link connector 308. The distal link body 302 has a central opening that is configured so that the camera assembly 304 and lighting assembly 306 can be removably positioned in the distal link body 302. Some or all of the distal link extension assembly 202 can be removed from the second assembly 14, and replaced, for example, during a resterilization between uses of the second assembly 14. A camera lens 305 and a diffusing lens 322 can be exposed at one end of the distal link body 302. In other embodiments, the camera assembly 304 and/or the lighting assembly 306 are external to the distal link body 302, for example, positioned at the surface of the distal link body 302. The link connector 308 can be coupled to the other end of the distal link body 302.

Accordingly, the connecting link 115 and the distal link extension assembly 202 can articulate relative to each other during operation.

The lighting assembly 306 is positioned between the camera assembly 304 and a field of view. The lighting assembly 306 includes a diffusing lens 322 or related camera lens filter that diffuses or scatters light produced by the lighting assembly 306, for providing a uniform field of view. The diffusing lens 322 can be coupled to a printed circuit board (PCB) 324 having one or more light sources 375. The light sources 375 may include electron stimulated light sources such as electron stimulated luminescence light sources, incandescent light sources such as incandescent light bulbs, electroluminescent light sources such as light-emitting diodes (LEDs), and gas discharge light sources such as fluorescent lamps, or related sources that produce high power light.

The lens barrel 502 can include a seat, for example, a tangential seat, at which the front lens 504 can be radially and/or axially aligned by a tangent contact with respect to an optical surface of the front lens 504. The front lens 504 can collect electromagnetic radiation such as light from a predetermined field of view, for example a field of view between 50° and 135°, such as a field of view of approximately 82°.

The lens assembly 410 can include one or more additional optics such as a polarizing or filtering lens, which can be constructed and arranged to control glare, reduce reflected lights from instruments (e.g. laser flare), or reduce other undesirable effects. One or more lenses described herein can filter one or more wavelengths (e.g. IR or visible light wavelengths) such as to accentuate features, colors, etc., to reduce or eliminate external light, and/or to provide a trigger signal. In an embodiment, a filtering lens can be constructed and arranged to allow particular wavelengths to pass ranging from 400 nm to 700 nm. In an embodiment, the filtering lens can be constructed and arranged to block infrared wavelengths, e.g. wavelengths ranging from 700 nm to 1105 nm. In an embodiment, the filtering lens can be constructed and arranged to block ultraviolet wavelengths ranging from 1 nm to 400 nm. In an embodiment, the filtering lens can be constructed and arranged to block LISA laser wavelengths for example, 2000 nm wavelength.

The spacer 506 provides an axial and/or radial alignment for the meniscus lens 508, the spacer 510, and an aperture/filter assembly 530. The meniscus lens 508 can direct light or other electromagnetic radiation at the camera aperture. Radial and/or axial alignment of the meniscus lens 508 can be established by a tangent contact of the spacer 506 with its optical surface. The spacer 510 provides an axial location for aperture/filter assembly 530, which comprises a filter glass 512, a lens 514, and a lens 516.

The lens 516 can comprise a meniscus lens (as shown) that is mounted to the lens 514 (e.g. cemented) such that light exiting the lens 514 is directed toward the concave surface of the lens 516. In an embodiment, the filter glass 512 prevents predetermined wavelengths from being transmitted, for example, a 2 μm wavelength. The filter glass 512 can include an opaque coating that creates an aperture to limit an amount of light reaching an image sensor, such as the image sensor 418 of FIG. 4B. The spacer 506 can provide a radial alignment of the filter glass 512. The spacer 510, in particular, a flat surface of the spacer 510, can provide an axial alignment of the filter glass 512. In some embodiments, a radial and axial alignment of the aperture/filter assembly 530 with respect to the filter glass 512 is set during manufacturing.

The spacer 518 can provide an axial and/or a radial alignment for a triplet assembly 540, which comprises a lens 520, a lens 522, and a lens 524.

The lens 522 can comprise a concave-concave lens (as shown) which receives the light from the lens 522 and directs light onto the lens 524. The lens 524 can comprise a convex-convex lens (as shown) which receives the light from the lens 522 and directs light towards an image sensor, such as the image sensor 418 of FIG. 4B. The triplet assembly 540 provides color correction and focuses light on the sensor 418. The triplet assembly 540 can set a radial and axial alignment by tangent contact of spacer 518 with an optical surface.

The lens retainer 526 compresses the lens stack together to maintain their respective alignments. Lens retainer 526 can be constructed and arranged to sufficiently compress the multiple lenses of the lens assembly 410. The lens retainer 526 can also provide centering from a rear of the triplet assembly 540 by contacting lens 524 at a tangent with respect to the optical surface.

The lens mount 412, also referred to as a calibration adjustment nut, attaches the lens assembly 410 to the assembly 304 of FIG. 4A. The lens mount 412 is aligned with the sensor 418 by a close tolerance fit rectangular cavity that surrounds the sensor 418, thus providing an accurate alignment of the lens assembly 410 to the sensor 418. The lens mount 412 can include a thread for attaching to the lens assembly 410, allowing focus adjustments to be made, for example, by rotating the lens assembly 410 to achieve an optimal optical distance to the sensor 418.

When describing the method 600, reference is made to FIG. 1. Although the method 600 refers to a sequence of blocks, or steps, the method 600 is not limited to this sequence. In other embodiments, various blocks can be performed in a different order. For example, block 604 can be performed prior to block 602.

At block 602, the second assembly 14 is attached to a third assembly 16 of one or more different third assemblies 16 used with second assembly 14, for example, over its lifetime.

At block 710, a new second assembly is attached to the (X+1)th third assembly. Accordingly, the robotic introducer system 10 is operational.

At block 712, an (X+1) procedure can be performed by the robotic introducer system 10, for example, a medical procedure.

FIG. 8 is a cross-sectional view of an optical assembly 800, in accordance with an embodiment. The optical assembly 800 can be constructed and arranged to be part of a distal link extension assembly 802 coupled to a distal end of a probe assembly, for example, the articulating probe assembly 120 described with reference to FIGS. 1-5. The distal link extension assembly 802 can be similar to the distal link extension assembly 202 described with reference to FIGS. 1-5. Repetitive details of the distal link extension assembly 802 will not be repeated for brevity. The optical assembly 800 can include elements similar to the camera assembly 304 and/or the lighting assembly 306 described with reference to FIGS. 1-5. Accordingly, details will not be repeated for brevity

The distal link extension assembly 802 can include a distal link body 803. At least one side port 837 extends from the distal link body 803. The side port 837 is constructed and arranged to receive a tool 810, for example, a cutter, a grasper, an energy delivery probe, a lighting fiber, etc. The optical assembly 800 can include a lens 804 that provides a first field of view, for example, collects images taken during a procedure. The optical assembly 800 can include an optical redirector 805 such as a mirror or prism that is adjacent the lens 804, and positioned so that an output of the lens 804, for example, optical pathways, are reflected from the optical redirector. For example, some of the optical pathway is directed towards the optical redirector 805, where it is then redirected toward the side port 837.

In this manner, the optical element 805 provides a second field of view that complements the first field of view of the lens 804. The combination of the lens 804 and the optical element 805 can provide a combined field of view that is up to 180°, and in some cases, greater than 180°. This feature permits an operator to view multiple images proximate distal link extension assembly 802. For example, as shown in FIG. 9, console system 150 can produce multiple images 902, 904a and 904b. Image 902 represents an image of a region in front of lens 804. Image 904a and 904b represent images of the tool ports 837 on either side of lens 804. In some embodiments, the optical element 805 is configured to allow viewing of a tool initially exiting a side port 837, where an image can be outside of the first field of view of lens 804, such as tool 810 shown.

FIG. 10 is a cross-sectional view of a robotic introducer system 1000 comprising a distal link extension assembly 1002, in accordance with an embodiment. The distal link extension assembly 1002 is coupled to a distal end of an articulating probe assembly 1020. The probe assembly 1020 can include elements that are the same as or similar to the articulating probe assembly 120 described herein, and will not be repeated for brevity.

The distal link extension assembly 1002 includes a base 1015, a body 1003 movably positioned in the base 1015, and an optical lens 1005 coupled to the body 1003. A plurality of body articulating cables 1010 extend along the probe assembly 1020 and the base 1015. A distal end of each articulating cable 1010 is attached to the body 1003. The articulating cables 1010 can be advanced or retracted in response to a force applied to the cables 1010 to move the body 1003 for changing a field of view of the lens 1005. The articulating probe assembly 1020 and the body 1003 are independently controllable. For example, the articulating cables 1010 can be advanced and retracted to move the body 1003 relative to an axis along which the robotic introducer system 1000 extends while the articulating probe assembly 1020 remains stationary along the axis.

The articulating probe assembly 1020 includes a plurality of probe links, for example, inner probe links and outer probe links similar to the probe assembly 120 described above and/or described in PCT Application No. PCT/US2012/032279, filed Apr. 5, 2012, the content of which is incorporated herein by reference above. The distal link extension assembly 1002 is adjacent a distal link 1036 of the probe links. The articulating probe assembly 1020 can include at least one steering cable that extends through the links and terminates at the distal link 1036. The steering cable and the body articulating cables 1010 are independently controllable.

The base 1015 can include a concave region, which can mate with a convex lower region of the body 1003. In an embodiment, the body 1003 is ball-shaped and is positioned in a cavity of the base 1015. Alternatively, the base 1015 can include a convex region, which can mate with a concave lower region of the body 1003. The coupling of the base 1015 and the body 1003 in this manner permits a rotation of the body 1003 relative to the base 1015 in response to a force applied to the body articulating cables 1010. The body 1003 and/or the base 1015 can have a cavity or a protruding region having other shapes, for example, semi-spherical, semi-ellipsoidal, or parabolic shape.

A plurality of guide holes 1066 (1066a-c shown) can extend from the probe assembly 1020. The articulating body cables 1010 can extend through the guide holes 1066. In an embodiment, each link 1036 in the articulating probe assembly 1020 has a guide hole 1066a, 1066b, 1066c (generally, 1066). Two or more guide holes 1066, for example, guide holes 1066a, 1066c can be aligned with each other to receive an articulating body cable 1010. A plurality of flexible tubes 1013 can extend through the guide holes 1066 along the probe assembly 1020. The tubes 1013 can be spaced equidistantly with respect to each other about the probe assembly 1020. The tubes 1013 can advance and retract with respect to the probe assembly for articulating the probe assembly 1020. The tubes 1013 can move in concert with, or independently of, a movement of the steering cables (not shown) extending through an interior of the links 1036. The body articulating cables 1010 and the tubes 1013 can operate to pan or tilt, the lens 1005 coupled to the body 1003. Alternatively or additionally, body articulating cables 1010 and the tubes 1013 can operate to zoom lens 1005 (e.g. by advancing the body 1003). A distal end of each of the tubes 1013 is coupled to the base 1015. A body articulating body cable 1010 extends through each tube 1013.

The lens 1005 can be part of a camera assembly, for example, a camera assembly described herein, such as a camera assembly contained in whole or in part in body 1003. Details of the camera assembly are not repeated for brevity. The body 1003 can include a hollow interior or include a cavity in which the camera assembly can be positioned. The lens 1005 is positioned at a top region of the body 1003 for providing a field of view.
