DETAILED DESCRIPTION

Reference will now be made to the drawings wherein like reference numerals identify similar structural features or aspects of the subject disclosure. For purposes of explanation and illustration, and not limitation, an illustrative view of an embodiment of a system in accordance with the disclosure is shown in FIG. 1 and is designated generally by reference character 100. Other embodiments and/or aspects of this disclosure are shown in FIGS. 2-54.

Referring to FIGS. 1-23 generally, and specifically to FIGS. 1-10, an access port system 100 can include a port body 101 configured to be inserted into an incision. Referring additionally to FIGS. 11-15, the port body 101 can define an imaging assembly opening 103 from a proximal side to a distal side thereof. The access port system 100 can include and an imaging assembly 105 configured to pass through the imaging assembly opening 103 to allow imaging of an interior portion of a patient body.

In certain embodiments, the port body 101 can be flexible (e.g., made of elastomeric material) and a housing 105a of the imaging assembly can be rigid (e.g., made of hard plastic or metal). In certain embodiments, the port body 101 can also define an instrument channel 107 from the proximal side thereof to the distal side to allow an instrument pass through to perform a medical procedure. In certain embodiments, e.g., as shown in FIGS. 19-22, the port body 201, 301 may not have an instrument channel, but only an imaging assembly opening 103, 303. The port body 201, 301 may be otherwise similar to the port body 101 as disclosed herein, or may be different in any suitable manner appreciated by those having ordinary skill in the art in view of this disclosure.

In certain embodiments, the port body 101 can include one or more anchors 109a, 109b extending from the port body 101. The one or more anchors 109a, 109b can include a heal anchor 109a adjacent the distal side of the port body 101, e.g., as shown. The one or more anchors 109a, 109b can include a toe anchor 109b disposed on an opposite side of the port body 101 relative to the heal anchor 109a and proximal of the heal anchor 109a, e.g., as shown.

In certain embodiments, referring to FIGS. 2 and 11, the imaging assembly 105 can include an imaging assembly radial portion 111a configured to house an imaging device 113 (e.g., a camera) disposed therein. The imaging assembly 105 can include an imaging assembly leg portion 111b extending proximally from the radial portion 111a (e.g., at an angle as shown). For example, the imaging assembly 105 can include a boot shape, e.g., as shown. In certain embodiments, the leg portion 111b can be angled at a non-right angle to the radial portion 111a.

The imaging assembly 105 can include an imaging device 113 located in the radial portion 111a at a radially outward position thereof, e.g., radially away from the leg portion 111b. A transparent layer 115 (e.g., made of glass or plastic) can be disposed on a distal side of the imaging device 113 (e.g., along the length of the radial portion 111a). The imaging assembly 105 can include one or more irrigation ports 117 (e.g., defied through the transparent layer 115) disposed proximate to the imaging device 113 to provide irrigation proximate the imaging device 113 (e.g., to clean the transparent layer 115 where the imaging device 113 is located).

The imaging assembly 105 can include one or more irrigation channels 119 connected to one or more irrigation ports 117. The one or more irrigation channels 119 can extend from the one or more irrigation ports 117, through the radial portion 111a, and through the leg portion 111b to a proximal end of the leg portion 111b (e.g., and exit therefrom), e.g., as shown. In certain embodiments, the housing 105a may include a data port (e.g., USB-C, USB3.0, or other suitable port) disposed at a proximal side thereof (e.g., shown having a data cable plugged in).

In certain embodiments, the port body 101 can include one or more insufflation 121 defined therethrough. The one or more insufflation ports 121 may include a tube connected or disposed therein, e.g., as shown in FIGS. 1-10.

Referring to FIGS. 7-9, in certain embodiments, the port body 101 and the imaging assembly 105 can be configured such that the port body 101 allows the imaging assembly 105 to rotate within the port body 101. For example, the port body 101 can define a window 123 (e.g., a portion of the distal end of the imaging assembly opening 103) that limits a rotation of the radial portion 111a of the imaging assembly 105. For example, the window 123 can be sized limit rotation of the radial portion to about 25 degrees or less, e.g., about 19 degrees as shown. Any suitable limit is contemplated herein.

In certain embodiments, as shown in FIG. 9, the non-right angle between the leg portion 111b and the radial portion 111a causes a lifting angle 125 when rotated within the port body 101. For example, the lifting angle 125 can be about 3 degrees, e.g., as shown. Any suitable lifting angle 125, and any suitable non-right angle of the leg portion 111b is contemplated herein. In certain embodiments, e.g., as shown best in FIG. 2, the leg portion 111b can house imaging electronics (e.g., circuit board 127, data cable 129 to imaging device 113, and/or data port 131) and/or can act as a handle for rotation of the imaging assembly 105, for example. Any other suitable features are contemplated herein.

In certain embodiments, the non-right angle of the radial portion 111a between the rotatable axis and the vector of the radial extension of the radial portion 111a can be between about 30 degrees and about 120 degrees. The effect of decreasing the angle can cause an increase in the change of viewing angle. The angle of viewing can be further adjusted by the raising or lowering a slope of the lower surface of the radial extension from the tip to the leg portion 111b. Furthermore, the combination of variability of these characteristics can allow for the device to function facing any direction around an incision, for example.

Referring to FIGS. 16-18, in certain embodiments, instead of a boot shape for example, the imaging assembly 205 can be a straight member having an angled distal face 211. An imaging device 113 can be disposed at the angled distal face 211 to provide an angled view when inserted through the port body, e.g., 101, 201. The imaging assembly 205 can include one or more irrigation ports 217 disposed at the angled distal face 211 proximate the imaging device 113. The imaging assembly 205 can otherwise include any suitable features of the imaging assembly 105 fit into the straight housing (e.g., electronics, data port, irrigation channels, etc.). Any suitable software and/or hardware modules for imaging and/or performing any other procedure are contemplated herein.

Referring to FIG. 23-33, another embodiment of an access port system 400 is shown in accordance with this disclosure. FIGS. 34-43 show an embodiment of a port body 401 of the embodiment of a system 400, shown in isolation. FIGS. 44-52 show an embodiment of an imaging assembly housing 405a of the embodiment of a system 400, shown in isolation.

The system 400 can be similar to the system 100 in certain embodiments. For example, the system can have a port body 401 that can be configured to be inserted into an incision, and the port body 401 can define an imaging assembly opening 403 from a proximal side to a distal side thereof.

The port body 401 can be similar to the port body 101, 201, 301 in certain embodiments. For example, the port body 401 can be made of a flexible material (e.g., silicone). The port body 401 can include an instrument channel 407 and an insufflation port 421. The port body 401 can include a swept back shape as shown, e.g., as opposed to a more rounded shape as shown for the port body 101, 201, 301. The swept back shape can allow for a smaller incision to be made.

The system 400 can include an imaging assembly 405 configured to pass through the imaging assembly opening 403 to allow imaging of an interior portion of a patient body (e.g., an abdomen location, e.g., a gallbladder area). The imaging assembly 405 can include an imaging assembly housing 405a. The imaging assembly housing 405a can include a similar overall shape as assembly 105 (e.g., a boot shape having a leg portion 411b and radial portion 411a). The imaging assembly housing 405a can have about a 90 degree angle between the radial portion 411a and the leg portion 411b. Any suitable angle is contemplated herein.

The imaging assembly 405 can include similar components (e.g., imaging devices, cables, etc.) and in similar locations to the imaging assembly 105 for example. For example, the imaging assembly 405 can include an imaging device and/or lighting in the radial extension 411a (e.g., a locations. One or more cables (e.g., a MIPI cable) can travel through the interior cavity of the imaging assembly housing 405a to a location to be connected. A transparent layer (not shown, similar to layer 115), e.g., made of glass or plastic, can be disposed on a distal side of the imaging device (e.g., along the length of the radial portion 411a).

As shown, the imaging assembly housing 405a can include a swept back shape. For example, the imaging assembly housing can have an oval cross-sectional shape. Such a swept back shape can allow for a reduction in the width of the entire system 400 including the port body 401. For example, as shown, the imaging assembly opening 403 can include a complimentary shape to the imaging assembly housing 405a to create a suitable seal. Any suitable shape to allow for a seal is contemplated herein. As disclosed above, the port body 401 can also include a swept back shape aiding in reduction of overall width and reduction in incision size, for example. Any other suitable form factor for reducing incision size is contemplated herein. In certain embodiments, the components of system 400 can be sized to allow for an 8 mm incision or smaller.

The port body 401 can define a window 423 (e.g., a portion of the distal end of the imaging assembly opening 403) where the radial extension 411a of the imaging assembly 405 extends from. For example, the window 123 can be sized to seal against the radial extension 411a. As shown, the oval shape for the imaging assembly housing 405a and complimentary shaped opening 403 can prevent rotation of the housing 405a relative to the port body 401, and a wider window with clearance is not necessary for the system 400. As shown, the imaging assembly 405 can be fixed in relative rotational position to the port body 401. The port body 401 and/or the opening 403 can be shaped to prevent rotation of the imaging assembly 405, unlike the embodiment of FIG. 1. The port body 401 can include any suitable openings, ports, etc. as appreciated by those having ordinary skill in the art in view of this disclosure (e.g., as described above with respect to other embodiments).

The imaging assembly housing 405a can be made of a rigid material in certain embodiments. The imagine assembly housing 405a can be inserted through the imaging assembly opening 403 (e.g., which is made easier by the port body 401 being compliant).

Once assembled, the system 400 can be inserted into an incision (e.g., in a shoehorning motion). The area can be insufflated if desired, e.g., through port 421. Images can be received from the imaging device in the radial extension 411a and the surgical area can be viewed. The surgical site can be accessed via the instrument channel 407 while viewing the area.

Certain embodiments of this disclosure can employ one or more imaging devices, e.g., as disclosed above. Certain image processing can be conducted on data received from the imaging device. For example, in the embodiment of a system 400, where the imaging assembly 405 may be fixed relative to the port body 401, no mechanical movement of the imaging device may be possible. In fact, certain embodiments, e.g., system 400, may have no moving parts at all. In view of this, embodiments can include an image processing module configured to allow digital movement of an image in situ. For example, where a resolution of a camera is sufficiently high (e.g., 4K), no magnification may be needed (e.g., at the distances of an abdominal procedure using insufflation). The resolution of the surgical site with an unmagnified camera of suitable resolution can be equivalent or better than a traditional endoscope provides. In such embodiments, the image processing module (which can be located internal or external to the system 400), can receive one or more commands from a user to provide a digital zoom and/or pan of the images/video stream.

The image processing module can be configured to connect to a controller (e.g., a dual joystick controller and/or any other suitable controller) to receive the commands. For example, one stick can control zoom, and another stick can control vertical and lateral pan. The image processing module can be configured to output the processed images/video stream to a screen for the user to view in real time. Any suitable input mechanism for digital image pan and/or zoom is contemplated herein. Such a control mechanism eliminates the need to learn reverse control of an endoscope in use, speeds up target image acquisition, and reduces chances for error. Such control schemes also allow elimination of moving parts and a wider field of view overall. Any other suitable additional image processing (e.g., dewarping to create a flat image, 3D image creation using different flashing light positions to provide differing shadows, etc.) are contemplated herein.

As will be appreciated by those skilled in the art, aspects of the present disclosure may be embodied as a system, method or computer program product. Accordingly, aspects of this disclosure may take the form of an entirely hardware embodiment, an entirely software embodiment (including firmware, resident software, micro-code, etc.), or an embodiment combining software and hardware aspects, all possibilities of which can be referred to herein as a “circuit,” “module,” or “system.” A “circuit,” “module,” or “system” can include one or more portions of one or more separate physical hardware and/or software components that can together perform the disclosed function of the “circuit,” “module,” or “system”, or a “circuit,” “module,” or “system” can be a single self-contained unit (e.g., of hardware and/or software).

Those having ordinary skill in the art understand that any numerical values disclosed herein can be exact values or can be values within a range. Further, any terms of approximation (e.g., “about”, “approximately”, “around”) used in this disclosure can mean the stated value within a range. For example, in certain embodiments, the range can be within (plus or minus) 20%, or within 10%, or within 5%, or within 2%, or within any other suitable percentage or number as appreciated by those having ordinary skill in the art (e.g., for known tolerance limits or error ranges).

The articles “a”, “an”, and “the” as used herein and in the appended claims are used herein to refer to one or to more than one (i.e., to at least one) of the grammatical object of the article unless the context clearly indicates otherwise. By way of example, “an element” means one element or more than one element.

The phrase “and/or,” as used herein in the specification and in the claims, should be understood to mean “either or both” of the elements so conjoined, i.e., elements that are conjunctively present in some cases and disjunctively present in other cases. Multiple elements listed with “and/or” should be construed in the same fashion, i.e., “one or more” of the elements so conjoined. Other elements may optionally be present other than the elements specifically identified by the “and/or” clause, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, a reference to “A and/or B”, when used in conjunction with open-ended language such as “comprising” can refer, in one embodiment, to A only (optionally including elements other than B); in another embodiment, to B only (optionally including elements other than A); in yet another embodiment, to both A and B (optionally including other elements); etc.

As used herein in the specification and in the claims, “or” should be understood to have the same meaning as “and/or” as defined above. For example, when separating items in a list, “or” or “and/or” shall be interpreted as being inclusive, i.e., the inclusion of at least one, but also including more than one, of a number or list of elements, and, optionally, additional unlisted items. Only terms clearly indicated to the contrary, such as “only one of” or “exactly one of,” or, when used in the claims, “consisting of,” will refer to the inclusion of exactly one element of a number or list of elements. In general, the term “or” as used herein shall only be interpreted as indicating exclusive alternatives (i.e., “one or the other but not both”) when preceded by terms of exclusivity, such as “either,” “one of,” “only one of,” or “exactly one of.”

Any suitable combination(s) of any disclosed embodiments and/or any suitable portion(s) thereof are contemplated herein as appreciated by those having ordinary skill in the art in view of this disclosure.

The embodiments of the present disclosure, as described above and shown in the drawings, provide for improvement in the art to which they pertain. While the subject disclosure includes reference to certain embodiments, those skilled in the art will readily appreciate that changes and/or modifications may be made thereto without departing from the spirit and scope of the subject disclosure.
