BACKGROUND

The present disclosure relates generally to systems, devices, and methods, and more specifically, relates to systems, devices, and methods for use in performing procedures via a single incision or a natural orifice.

Conventional surgical procedures will generally require one or more large incisions to a patient in order for the surgical team to perform a surgical action. With the advancement of medical science and technology, most conventional open surgical procedures have been largely replaced with minimally invasive surgery (MIS) procedures. Recent developments in respect to computer-assisted and/or robotic surgical technology have contributed to advancements in MIS, including the ability to translate a surgeon's desired actions into movements of robotic instruments inside the body cavity of a patient.

BRIEF SUMMARY

Despite recent developments in modern medical science and technology, it is recognized in the present disclosure that one or more problems are encountered in modern surgical technology and methodology. For example, a typical MIS procedure requires multiple incisions to a patient in order to allow access via the incisions for the insertion of a camera and various other laparoscopic instruments into the body cavity of the patient.

As another example, surgical robotic devices oftentimes encounter difficulties during surgical procedures due to insufficient anchoring and/or reactive forces to stabilize against forces that are desired and/or necessary to be applied during surgical actions.

It is also recognized in the present disclosure that surgical robotic systems face difficulties in providing an instrument, such as a cutting or gripping instrument attached to the end of a surgical robotic arm, with access to all or even most parts, areas, and/or quadrants of abdominal cavity of a patient. That is, after the surgical robotic arm is inserted in the abdominal cavity of the patient and ready to perform a surgical action, the instrument attached to the end of the surgical robotic arm is typically limited to access only certain parts, areas, and quadrants of the abdominal cavity of the patient.

In yet another example, known surgical robotic systems typically provide only between one to two surgical robotic arms per access or opening (such as an incision or a natural orifice) of the patient. In this regard, one or more additional incisions will be required for the insertion of a camera and various laparoscopic instruments into the abdominal cavity of the patient.

As another example, while known surgical robotic systems have been designed for use in an abdominal cavity of a patient to perform forward-directed surgical procedures, such systems have not been designed for and may encounter problems when applied in situations requiring reverse-directed surgical procedures. For example, such known surgical robotic systems have not been designed for deployment through a natural orifice, such as a rectum or vagina, for performing natural orifice transluminal endoscopic surgery (or NOTES), such as pelvic gynecological and/or urological procedures. Such systems may encounter one or more problems, such as the inability to access certain organs, tissues, or other surgical sites upon insertion into the natural orifice.

DETAILED DESCRIPTION

Example embodiments will now be described with reference to the accompanying drawings, which form a part of the present disclosure, and which illustrate example embodiments which may be practiced. As used in the present disclosure and the appended claims, the terms “example embodiment,” “exemplary embodiment,” and “present embodiment” do not necessarily refer to a single embodiment, although they may, and various example embodiments may be readily combined and/or interchanged without departing from the scope or spirit of example embodiments. Furthermore, the terminology as used in the present disclosure and the appended claims is for the purpose of describing example embodiments only and is not intended to be limitations. In this respect, as used in the present disclosure and the appended claims, the term “in” may include “in” and “on,” and the terms “a,” “an” and “the” may include singular and plural references. Furthermore, as used in the present disclosure and the appended claims, the term “by” may also mean “from,” depending on the context. Furthermore, as used in the present disclosure and the appended claims, the term “if” may also mean “when” or “upon,” depending on the context. Furthermore, as used in the present disclosure and the appended claims, the words “and/or” may refer to and encompass any and all possible combinations of one or more of the associated listed items.

It is recognized in the present disclosure that, despite recent developments in medical science and technology, one or more problems are encountered in modern surgical technology and methodology, including MIS. For example, a typical MIS procedure requires multiple incisions to a patient in order to allow access via the incisions for the insertion of a camera and various other laparoscopic instruments into the body cavity of the patient.

In addition to the aforementioned disadvantages pertaining to the multiple and rather large incisions, it is recognized in the present disclosure that surgical robotic systems, including surgical robotic arms (and those instruments attached to them), developed for performing robotic-assisted MIS surgical procedures also suffer from one or more problems. For example, it is recognized herein that a major technical challenge for a surgical robotic system is the difficulty in providing sufficient anchoring and/or reactive forces to stabilize against forces that are desired and/or necessary to be applied to the patient by the surgical robotic system during a surgical action. In this regard, certain surgical actions for known surgical robotic systems may require tremendous effort and time, and may not be performed properly or at all as a result of the problem of insufficient anchoring and/or reactive forces.

Another example of a problem recognized in the present disclosure as being encountered by surgical robotic systems is the difficulty in providing an instrument, such as a cutting and/or gripping instrument attached to the end of a surgical robotic arm, with access to all or even most parts, areas, and quadrants of an abdominal cavity of a patient after the surgical robotic system has been set up (or installed) and is ready to perform a surgery. That is, after the surgical robotic arm of the system has been inserted, attached, and properly set up in the abdominal cavity of the patient and is ready to perform a surgical action, the instrument attached to the end of the surgical robotic arm is typically limited to access only certain parts, areas, and quadrants of the abdominal cavity of the patient. It is recognized in the present disclosure that such problems result in large from the limited number of possible degrees of freedom that can be provided by known surgical robotic systems and arms, and more specifically, the limited number of in vivo degrees of freedom (i.e. the degrees of freedom provided within an abdominal cavity of a patient) of known surgical robotic systems and arms. In this regard, surgical robotic systems typically provide only between 2 to 4 in vivo degrees of freedom for each surgical robotic arm.

As another example, while known surgical robotic systems have been designed for use in an abdominal cavity of a patient to perform forward-directed surgical procedures, such systems have not been designed for and may encounter problems when applied in situations requiring reverse-directed surgical procedures. For example, such known surgical robotic systems have not been designed for deployment through a natural orifice, such as a rectum or vagina, for performing natural orifice transluminal endoscopic surgery (or NOTES), such as trans-vaginal gynecological procedures in women and trans-rectal urological procedures in men. Such systems may encounter one or more problems, such as the inability to access certain organs, tissues, or other surgical sites upon insertion into the natural orifice.

Surgical systems, devices, and methods, including those for use in MIS and natural orifice transluminal endoscopic surgery (or NOTES), are described in the present disclosure for addressing one or more problems of known surgical systems, devices, and methods, including those described above and in the present disclosure. It is to be understood that the principles described in the present disclosure can be applied outside of the context of MIS and/or NOTES, such as performing scientific experiments and/or procedures in environments that are not readily accessible by humans, including in a vacuum, in outer space, and/or under toxic and/or dangerous conditions, without departing from the teachings of the present disclosure.

The Surgical System (e.g., Surgical Device 200)

An illustration of an example embodiment of a surgical device or system (e.g., surgical device or system 200) operable to be inserted into an abdominal cavity of a patient through a single access or opening (e.g., a single incision (such as an incision in or around the umbilical area) or through a natural orifice (such as a rectum or vagina, for performing natural orifice transluminal endoscopic surgery (or NOTES), hereinafter referred to as an “opening”) of the patient is depicted in FIG. 2A and FIG. 2B. The surgical device may then be anchored so as to position the surgical device 200 in the opening. The surgical device 200 may comprise a port assembly 210 and an instrument arm assembly 230. The surgical device 200 may also comprise other elements, such as one or more other instrument arm assemblies, one or more image capturing assemblies, one or more assistant arm assemblies, etc.

As illustrated in FIG. 1A and FIG. 1B, the surgical device 200 may be provided with an external anchor 1 attachable to the port assembly 210. The external anchor 1 may comprise a configurable assembly of segments 2, 6, 10, and 14 in communication with one another via joints or connecting portions 4, 8, and 12, and external anchor connector 16. The external anchor 1 may be operable to securely fix the position and/or orientation (hereinafter “position”) of the port assembly 210 in or about the single opening of the patient, and may also be operable to provide sufficient anchoring and/or reactive forces to stabilize against forces desired and/or necessary to be applied by at least one or more elements of the surgical device 200, including the instrument arm assembly 230, during a surgical action or procedure. The external anchor 1, which may also be in the form of the controllable swivel assembly 1000 illustrated in FIG. 10A and FIG. 10B, may be operable to cooperate with the port assembly 210 to provide one or more in vitro degrees of freedom. For example, the external anchor 1 may be configurable to provide 3 in vitro degrees of freedom. In example embodiments, the one or more in vitro degrees of freedom may include a torsional movement, pivotal movement, telescopic movement, and/or other movements of the port assembly 210 relative to the external anchor 1. For example, a torsional movement of the port assembly 210, as illustrated by arrow A in FIG. 1B, may allow one or more attached instruments, including an instrument arm assembly 230, to re-position during a surgical procedure (i.e. after set up or installation) so as to access other parts, areas, and/or all quadrants of the abdominal cavity of the patient. As another example, a pivotal movement of the port assembly 210, as illustrated by arrow B in FIG. 1B, may allow the port assembly 210 to be positioned in one of a plurality of angles with respect to opening of the patient, and may also allow attached instruments, including the instrument arm assembly 230, to re-position during a surgical procedure (i.e. after set up or installation) so as to access distal areas of the abdominal cavity of the patient. The other joint portions of the external anchor 1 may also be operable to cooperate and/or assist in desired movements of the port assembly 210. The external anchor 1 may be anchored to one or more stationary or fixedly positioned objects, such as a side rail 300 of a surgical table/bed illustrated in FIG. 1A. FIGS. 10A and 10B illustrate other example movements that provide for additional in vitro degrees of freedom via an example embodiment of the external anchor (controllable swivel assembly) 1000. The controllable swivel assembly 1000 will be further described below in at least the section “(1) Providing the external anchor and installing the port assembly.”

The surgical device 200 may further comprise one or more additional instrument arm assemblies, such as a second instrument arm assembly 240 illustrated in FIGS. 3A and 3B, attachable to the port assembly 210. One or more of the instrument arm assemblies, including the first instrument arm assembly 230, the second instrument arm assembly 240, a third instrument arm assembly (not shown), a fourth instrument arm assembly (not shown), etc., may be attachable or securable to the port assembly 210. Such instrument arm assemblies may be operable to access and perform one or more surgical actions in/on any and all parts, areas, and/or quadrants within a cavity of the patient. For example, surgical device 200 may be configurable to perform surgical actions in a forward direction (or “forward-directed position” or “forward position”) (e.g., as illustrated in FIGS. 2B and 3B). As another example, surgical device 200 may be configurable to perform surgical actions in a reverse direction (or “reverse-directed position” or “reverse position”) (e.g., as illustrated in FIGS. 2A and 3A).

The surgical device 200 may also comprise one or more image capturing assemblies, such as image capturing assembly 220. The surgical device 200 may further comprise one or more assistant arm assemblies, such as a retractor arm assembly 250, as illustrated in FIGS. 2A, 2B, 3A, and 3B. Furthermore, the surgical device 200 may comprise one or more other instrument arm assemblies, such as suction/irrigation assembly 260, illustrated in FIGS. 2A, 2B, 3A, and 3B, that can be inserted into the opening of the patient via the port assembly 210 before, during, and/or after performing a surgical action or procedure. It is to be understood in the present disclosure that the surgical device 200 may be configurable in a plurality of configurations and arrangements, including having more or less than two instrument arm assemblies (such as third, fourth, fifth, etc. instrument arm assemblies), more than one image capturing assembly (such as second, third, etc. image capturing assemblies), more or less than one assistant arm assembly (such as second, third, etc. assistant arm assemblies), and/or more or less than one other laparoscopic tool in example embodiments without departing from the teachings of the present disclosure.

The Port Assembly (e.g., Port Assembly 210)

An example embodiment of the port assembly (e.g., port assembly 210) is illustrated in FIGS. 2A, 2B, 3A, 3B, FIG. 4A, FIG. 4B, FIG. 4C, and FIG. 4D. The port assembly 210 may be configurable to be inserted in or about a single opening of the patient (such as a single incision or a natural orifice) and fixed in position by at least the external anchor (such as the external anchor 1 illustrated in FIGS. 1A and 1B and the controllable swivel assembly 1000 illustrated in FIGS. 10A and 10B).

The port assembly 210 may be an elongated structure having a central access channel 210a formed through the port assembly 210. The central access channel 210a may be for use in inserting and removing instruments, such as one or more instrument arm assemblies 230, 240, one or more image capturing assemblies 220, one or more assistant arm assemblies 250, 260, etc. In an example embodiment, the port assembly 210 may include a first end section 212 and a second end section 214. The first end section 212 and second end section 214 may be fixably attachable to one another or formed as a unitary article. The port assembly 210 may also include a mid section 213 between the first end section 212 and the second end section 214. The first end section 212, second end section 214, and mid section 213 may be fixably attachable to one another, as illustrated in FIGS. 4A and 4B, or two or more of these sections may be formed as a unitary article. In an example embodiment, the first end section 212 may be the portion of the port assembly 210 that is secured to the external anchor 1, and the port assembly 210 may be fixed in position at an angle θ relative to the singe opening of the patient of between about 0 to +/−90 degrees. These and other elements of the port assembly 210 will now be described below and with reference to FIGS. 2A, 2B, 3A, 3B, and 4A-D.

As illustrated in at least FIGS. 4A and 4B, the port assembly 210 may comprise a first end section 212. The first end section 212 may have a first end channel 212a formed through the first end section 212. The first end channel 212a may be considered as a part of the central access channel 210a. The first end section 212 may also include a portion operable to be secured to the external anchor 1, such as a portion on an exterior portion of the first end section 212.

The first end section 212 may also include a first gate assembly 212b, as illustrated in FIGS. 4A, 4C, and 4D. The first gate assembly 212 may be configurable to control access through the first end channel 212a. For example, the first gate assembly 212b may be configurable to be in an open position, as illustrated in FIG. 4C, so as to allow access through the first end channel 212a. The first gate assembly 212b may also be configurable to be in a closed position, as illustrated in FIG. 4D, so as to prevent or restrict access through the first end channel 212a. The first gate assembly 212b may also be configurable to be in a partially closed (or partially opened) position (not shown). The first gate assembly 212b may also be configurable to transition between the closed position and the open position.

In an example embodiment, the first gate assembly 212b may be provided within the first end section 212 in such a way that, when the first gate assembly 212b is configured to be in the open position, as illustrated in FIG. 4C, the first end channel 212a is substantially or completely unobstructed by the first gate assembly 212b. The first gate assembly 212b may be configured to be in the open position when a surgeon desires to insert (or remove) an instrument into (or out of) the cavity of the patient via the first end channel 212a (and the rest of the central access channel 210a).

Similarly, the first gate assembly 212b may be provided within the first end section 212 in such a way that, when the first gate assembly 212b is configured to be in the closed position, as illustrated in FIG. 4D, the first end channel 212a is substantially or completely obstructed by the first gate assembly 212b. The first gate assembly 212b may be configured to be in the closed position when a surgeon desires to maintain an insufflation of the cavity of the patient and/or when the surgeon does not need to insert (or remove) an instrument into (or out of) the cavity of the patient via the first end channel 212a.

The first gate assembly 212b may include a first expandable portion 212b configurable to expand when the first gate assembly 212b is configured to the closed position, as illustrated in FIG. 4D. When the first gate assembly 212b is configured to the closed position, the first expandable portion 212b may be operable to substantially or completely block, among other things, a gas medium (and/or other medium) from passing through the first end channel 212a. For example, if the cavity of the patient is being insufflated using a gas, such as carbon dioxide (CO₂), the first gate assembly 212b (i.e., the first expandable portion 212b) may be configurable to substantially prevent the carbon dioxide gas from leaving the cavity of the patient through the first end channel 212a.

The first expandable portion 212b may include one or more first expandable members. For example, the first expandable portion 212b may include six expandable members, as illustrated in FIGS. 4C and 4D. It is to be understood that the first expandable portion 212b may include more or less than six expandable members without departing from the teachings of the present disclosure. Some or all of the first expandable members may be integrated together and/or in communication with one another, such as in a manner where some or all of the first expandable members are operable to receive pressure (i.e., gas medium) from a common or same first source 212b′. For example, when the first gate assembly 212b is configured to the closed position, the first source 212b′ may be configurable to provide a positive pressure (i.e., a supply of gas) so as to cause some or all of the first expandable members to expand and block the first end channel 212a (e.g., hermetically block the first end channel 212a). Similarly, when the first gate assembly 212b is configured to the open position, the first source 212b′ may be configurable to provide a negative pressure (i.e., remove gas) so as to cause one or more (or all) of the first expandable members to not expand (and/or contract) and unblock the first end channel 212a. It is to be understood that more than one first sources 212b′ may provide the positive pressure and negative pressure to the one or more expandable members without departing from the teachings of the present disclosure.

It is recognized in the present disclosure that the first gate assembly 212b may also include a valve (not shown), or the like, in addition to or in replacement of the first expandable portion 212b. The valve may be configurable to perform substantially the same actions of blocking the first end channel 212a when the first gate assembly 212b is configured to the closed position and unblocking the first end channel 212a when the first gate assembly 212b is configured to the open position. The valve may be any type of valve configurable to perform the actions described above and in the present disclosure. The valve may include, but is not limited to including, a ball valve, gate valve, etc., so long as the valve is configurable to substantially block/unblock the first end channel 212a and prevent a gas medium from passing through the first end channel 212a.

For example, the second gate assembly 214b may be configurable to be in an open position, as illustrated in FIG. 4C, so as to allow access through the second end channel 214a. The second gate assembly 214b may also be configurable to be in a closed position, as illustrated in FIG. 4D, so as to prevent or restrict access through the second end channel 214a. The second gate assembly 214b may also be configurable to be in a partially closed (or partially opened) position (not shown). The second gate assembly 214b may also be configurable to transition between the closed position and the open position.

In an example embodiment, the second gate assembly 214b may be provided within the second end section 212 in such a way that, when the second gate assembly 214b is configured to be in the open position, as illustrated in FIG. 4C, the second end channel 214a is substantially or completely unobstructed by the second gate assembly 214b. The second gate assembly 214b may be configured to be in the open position when a surgeon desires to insert (or remove) an instrument into (or out of) the cavity of the patient via the second end channel 214a (and the rest of the central access channel 210a).

Similarly, the second gate assembly 214b may be provided within the second end section 214 in such a way that, when the second gate assembly 214b is configured to be in the closed position, as illustrated in FIG. 4D, the second end channel 214a is substantially or completely obstructed by the second gate assembly 214b. The second gate assembly 214b may be configured to be in the closed position when a surgeon desires to maintain an insufflation of the cavity of the patient and/or when the surgeon does not need to insert (or remove) an instrument into (or out of) the cavity of the patient via the second end channel 214a.

The second gate assembly 214b may include a second expandable portion 214b configurable to expand when the second gate assembly 214b is configured to the closed position, as illustrated in FIG. 4D.

For example, if the cavity of the patient is being insufflated using a gas, such as carbon dioxide (CO₂), the second gate assembly 214b (i.e., the second expandable portion 214b) may be configurable to substantially prevent the carbon dioxide gas from leaving the cavity of the patient through the second end channel 214a.

The second expandable portion 214b may include one or more second expandable members. For example, the second expandable portion may include six expandable members, as illustrated in FIGS. 4C and 4D. It is to be understood that the second expandable portion 214b may include more or less than six expandable members without departing from the teachings of the present disclosure. Some or all of the second expandable members may be integrated together and/or in communication with one another, such as in a manner where some or all of the second expandable members are operable to receive pressure (i.e., gas medium) from a common or same second source 214b′. For example, when the second gate assembly 214b is configured to the closed position, the second source 214b′ may be configurable to provide a positive pressure (i.e., a supply of gas) so as to cause some or all of the second expandable members to expand and block the second end channel 214a (e.g., hermetically block the second end channel 214a). Similarly, when the second gate assembly 214b is configured to the open position, the second source 214b′ may be configurable to provide a negative pressure (i.e., remove gas) so as to cause some or all of the second expandable members to not expand (and/or contract) and unblock the second end channel 214a. It is to be understood that more than one second sources 214b′ may provide the positive pressure and negative pressure to the one or more expandable members without departing from the teachings of the present disclosure. It is also to be understood in the present disclosure that one or more of the first sources 212b′ and one or more of the second sources 214b′ may be the same or different sources.

It is recognized in the present disclosure that the second gate assembly 214b may also include a valve (not shown), or the like, in addition to or in replacement of the second expandable portion 214b. The valve may be configurable to perform substantially the same actions of blocking the second end channel 214a when the second gate assembly 214b is configured to the closed position and unblocking the second end channel 214a when the second gate assembly 214b is configured to the open position. The valve may be any type of valve configurable to perform the actions described above and in the present disclosure. The valve may include, but is not limited to including, a ball valve, gate valve, etc., so long as the valve is configurable to substantially block/unblock the second end channel 214a and prevent a gas medium from passing through the second end channel 214a.

In this regard, such movement of the first instrument 342 may be a rotation of a distal end of the first instrument 342 relative to a point on the second axis (e.g., axis B), and such point may serve as a pivot for such movement. In addition to or in replacement, the wrist driven portion 346a may be driven by the wrist drive portion 336a in such a way as to move the second instrument 344. For example, the wrist driven portion 346a may be driven to move the second instrument 344 relative to the second axis (e.g., axis B). In this regard, such movement of the second instrument 344 may be a rotation of a distal end of the second instrument 344 relative to a point on the second axis (e.g., axis B), and such point may serve as a pivot for such movement. In example embodiments, the wrist driven portion 346a may be driven by the wrist drive portion 336a in such a way as to collectively move the first instrument 342 and the second instrument 344. For example, the wrist driven portion 346a may be driven to collectively move the first instrument 342 and the second instrument 344 relative to the second axis (e.g., axis B). In this regard, such movement of the first instrument 342 and the second instrument 344 may be a collective rotation of a distal end of the first instrument 342 and distal end of the second instrument 344 relative to a point on the second axis (e.g., axis B), and such point may serve as a pivot for such movement.

The second gate assembly 214b may then be configured to the open position. It is recognized in the present disclosure that the workable volume/space in the cavity is maintained via the insufflation since the first gate assembly 212b is configured to the closed position. Once the second gate assembly 214b is in the open position, the image capturing assembly 220 may be inserted into the cavity of the patient and the anchor portion 220a secured to an anchor port 216. The second gate assembly 214b may then be configured to the closed position after the image capturing assembly 220 passes through the second gate assembly 214b. The multi-curvable body 222 of the image capturing assembly 220 may then be configured/controlled to curve in one or more locations along the multi-curvable body 222 so that the image capturing assembly 220 can be directed in a forward-directed position (as illustrated in FIGS. 2B and 3B).

The separate image capturing assembly 320 may also be inserted through the port assembly 210 in a similar manner as described above. Once inserted through the port assembly 210 and into the cavity of the patient, the separate image capturing assembly 320 may then be attached/secured to the interior wall of the cavity of the patient via the magnetic anchor 310.

(3) Inserting and Attaching a First Instrument Arm Assembly.

The instrument arm assembly 230 may be inserted through the central access channel 210a and secured to the anchor port 216 of the port assembly 210. To do so while maintaining the workable volume/space, the first gate assembly 212b may again be configured to the open position while the second gate assembly 214b is configured to the closed position. Once the first gate assembly 212b is in the open position, the instrument arm assembly 230 may be inserted into the mid section 213, as illustrated in FIG. 8B. The first gate assembly 212b may then be configured to the closed position after the instrument arm assembly 230 passes through the first gate assembly 212b and into the mid section 213, as illustrated in FIG. 8C. The second gate assembly 214b may then be configured to the open position, as illustrated in FIG. 8D. Once the second gate assembly 214b is in the open position, the instrument arm assembly 230 may be inserted into the cavity of the patient and the securing portion 231a secured to an anchor port 216, as illustrated in FIG. 8E. The second gate assembly 214b may then be configured to the closed position after the instrument arm assembly 230 passes through the second gate assembly 214b.

(5) Inserting and Attaching One or More Additional Instrument Arm Assemblies, One or More Assistant Arm Assemblies, and/or One or More Additional Camera Arm Assemblies.

The port assembly 210 may be inserted (e.g., action 706) into the opening (and cavity) of the patient and anchored in position using the external anchor 1 (e.g., action 708), and a workable volume/space in the cavity may be formed, such as via insufflation using CO₂and/or other gases, vacuum suction tools, and/or retractable hook tools. The controllable swivel assembly 1000 may also be used in example embodiments. For example, a workable abdominal cavity of about 10-12 cm in height may be provided for the patient. Thereafter, one or more image capturing assemblies 220, one or more assistant arm assemblies (e.g., action 710), and one or more assistant arm assemblies 250 or 260 (if needed) may be inserted into the port assembly 210 via the central access channel 210a, secured to the anchor ports 216, and configured in the cavity of the patient. For the inserting, each of the image capturing assemblies 220, instrument arm assemblies 230 and/or 240, and assistant arm assemblies 250 and/or 260 are inserted in reverse orientation as compared to the forward-directed position described above and in the present disclosure. A surgical action or procedure may then be performed in any part, area, and/or quadrant of the cavity of the patient using the surgical device 200. These processes will now be described below with references to at least FIGS. 7, 8F-K, 9B, and 10B.

(1) Providing the External Anchor and Installing the Port Assembly.

In an example embodiment, the port assembly 210 may be installed and secured to the external anchor 1 or 1000. As illustrated in FIGS. 8A-E, the second end 214 of the port assembly 210 is inserted into the opening of the patient and into the cavity of the patient and the first end 212 of the port assembly 210 is secured to the external anchor 1 or 1000. Thereafter, a workable volume/space in the cavity may be formed in the cavity of the patient, such as via insufflation using CO₂and/or other gases, vacuum suction tools, and/or retractable hook tools. Before doing so, the first gate assembly 212b and the second gate assembly 214b may be expanded to the closed position. Insufflation of the cavity may be achieved in one or more of a plurality of ways. For example, the insufflation port of the port assembly 210 may be used to provide the required insufflation.
