The present disclosure relates to seals. More particularly, the present disclosure relates to seals for surgical access devices.
In order to facilitate minimally invasive surgery, a working space must be created in the desired surgical plane. An injection of an insufflation fluid, typically CO2, can be used to create a pneumoperitoneum in the abdomen. To work in the created space, access ports are required for surgical instrumentation and cameras. These ports maintain the pressure creating the pneumoperitoneum with seals that adapt to the surgical instrumentation.
The breadth of surgical instrumentation on the market today requires a robust seal capable adjusting to multiple sizes and withstanding multiple insertions of surgical instrumentation. Therefore, it would be beneficial to have an access assembly with improved seal durability.
A cannula for use in an access assembly is provided. The cannula includes an instrument valve housing including first and second housing sections and defining a cavity and a valve assembly disposed within the cavity of the instrument valve housing. The valve assembly includes a seal assembly including an outer flange and a septum seal extending across the outer flange, a guard assembly disposed within the outer flange of the seal assembly, and a centering mechanism including an annular ring and a plurality of spokes extending outwardly from the annular ring. The guard assembly includes a plurality of guard members. Each guard member of the plurality of guard members includes a ring portion and a flap portion. The outer flange of the seal assembly is supported within the annular ring and the outer ring is disposed within the cavity of the instrument valve housing. The flap portions of the guard members of the guard assembly are configured to engage and stretch the septum seal during reception of a surgical instrument through the valve assembly.
In embodiments, the guard assembly includes first, second, third and fourth guard members. Each of the guard members may include a ring portion and a flap portion. The flap portions may not extend beyond a midline of the ring portions. The first and second flap portions may be disposed opposite one another, and the third and fourth flap portions may be disposed opposite one another. The first and second flap portions may be disposed perpendicular to the third and fourth flap portions. The flap portions may include a substantial mushroom cap shape.
The guard assembly of the valve assembly may further include upper and lower retainer members. At least one of the upper or lower retainer members may include a plurality of pins configured to engage the ring portions of the plurality of guard members. The flap portion of the first guard member may overlap the flap portion of the second guard member. The flap portion of the second guard member may overlap the flap portion of the third guard member. The flap portion of the third guard member may overlap the flap portion of the fourth guard member. The flap portion of the fourth guard member may overlap the flap portion of the first guard member.
Another cannula for use in an access assembly is provided. The cannula includes an instrument valve housing including first and second housing sections and defining a cavity, and a valve assembly disposed within the cavity of the instrument valve housing. The valve assembly includes a seal assembly including an outer flange and a septum seal extending across the outer flange, a guard assembly disposed within the outer flange of the seal assembly, and a centering mechanism including an annular ring and a plurality of spokes extending outwardly from the annular ring the guard assembly including a guard member having a ring portion and a plurality of petals. The outer flange of the seal assembly is supported within the annular ring. The plurality of petals of the guard member are configured to engage and stretch the septum seal during reception of a surgical instrument through the valve assembly.
In embodiments, each petal of the plurality of petals includes a flap portion and a connector portion. Each of the flap portions may be connected to the ring member by a respective connector portion. The plurality of petals may extend radially outward from the ring portion. The plurality of petals may be configured to be folded over the ring portion such that the flap portions overlap adjacent flap portions. Each of the flap portions may define one or more openings and the ring portion defines corresponding openings.
The guard assembly of the valve assembly may further include upper and lower retainer members. At least one of the upper or lower retainer members may include a plurality of pins. The one or more openings in the flap portions and the corresponding openings in the ring portion may be configured to receive the plurality of pins of the at least one upper or lower retainer members.
The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments of the disclosure and, together with a general description of the disclosure given above, and the detailed description of the embodiments given below, serve to explain the principles of the disclosure, wherein:
Particular embodiments of the present disclosure are described hereinbelow with reference to the accompanying drawings; however, it is to be understood that the disclosed embodiments are merely exemplary of the disclosure and may be embodied in various forms. Well-known functions or constructions are not described in detail to avoid obscuring the present disclosure in unnecessary detail. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present disclosure in virtually any appropriately detailed structure. Like reference numerals refer to similar or identical elements throughout the description of the figures.
As used herein, the term “distal” refers to that portion of the instrument, or component thereof which is farther from the user while the term “proximal” refers to that portion of the instrument or component thereof which is closer to the user.
Cannulas are employed during, e.g., laparoscopic surgery and may, in various embodiments, provide for the sealed access of laparoscopic surgical instruments into an insufflated body cavity, such as the abdominal cavity. The cannulas of the present disclosure include an instrument valve housing mounted on a cannula tube. Cannulas are typically part of a trocar assembly including a trocar obturator. The trocar obturator is insertable through the cannula to facilitate placement of the cannula through tissue. The cannula and the trocar obturator are separate components but are capable of being selectively connected together. For example, the trocar obturator may be inserted into and through the cannula until the handle of the trocar obturator engages, e.g., selectively locks into, the instrument valve housing of the cannula.
Trocar assemblies are employed to tunnel through an anatomical structure, e.g., the abdominal wall, either by making a new passage through the structure or by passing through an existing opening through the structure. Once the trocar assembly has tunneled through the anatomical structure, the trocar obturator is removed, leaving the cannula in place in the structure, e.g., in the incision created by the trocar assembly. The instrument valve housing of the cannula may include valves that prevent the escape of insufflation gases from the body cavity, while also allowing surgical instruments to be inserted into the cavity.
In various embodiments, a bladeless optical trocar obturator may be provided that permits separation of tissue planes in a surgical procedure and visualization of body tissue fibers as they are being separated, thereby permitting a controlled traversal across a body wall. In other embodiments, the trocar obturator may be bladeless without being optical, e.g., without providing contemporaneous visualization thereof through the distal tip of an obturator. The bladeless obturator may be provided for the blunt dissection of the abdominal lining during a surgical procedure.
Various trocar obturators suitable for use with the cannulas of the present disclosure are known and include, for example, bladed, bladeless, blunt, optical, non-optical. The trocar assemblies will only be described to the extent necessary to disclose the aspects of the present disclosure. For a detailed description of the structure and function of exemplary trocar assemblies, including exemplar trocar obturators and exemplar cannulas, please refer to commonly owned PCT Publication No WO 2016/186905 (“the '905 publication”), the content of which is hereby incorporated by reference herein in its entirety.

With particular reference to
The guard assembly 130 of the valve assembly 120 supported within the instrument valve housing 110 includes first, second, third, and fourth guard members 132, 134, 136, 138. The guard members 132, 134, 136, 138 are formed of rigid plastic or other suitable material. Each of the first, second, third, and fourth guard members 132, 134, 136, 138 includes a ring portion 132a, 134a, 136a, 138a and a flap portion 132b, 134b, 136b, 138b. The ring portions 132a, 134a, 136a, 138a of the first, second, third, and fourth guard members 132, 134, 136, 138 each define a plurality of openings 131, 133, 135, 137, respectively. Each opening of the plurality of openings 131, 133, 135, 137 is configured to receive a pin of a plurality of pins 146 of an upper retainer member 140.
Each of the flap portions 132b, 134b, 136b, 138b of the respective first, second, third, and fourth guard members 132, 134, 136, 138 of the guard assembly 130 extends radially inward from the ring portions 132a, 134a, 136a, 138a.

As shown in
It is envisioned that the guard assembly 130 may include a guard member (not shown) including a pair of opposed flap portions (not shown) supported on a single ring portion. In embodiments, the flap portions may extend radially outward from the ring portions, thereby necessitating folding the flap portions over the ring portions. See, for example, the embodiment of
Turning briefly to
With reference again to
Although the plurality of pins 146 is shown as extending downwardly from the base 144 of the upper retainer member 140 for engagement with the lower retainer member 142, in other embodiments, the plurality of pins 146 may instead extend upwardly from the base 148 of the lower retainer member 142 for engagement with the upper retainer member 140, or the pins 146 may extend from both the upper and lower retainer members 140, 142 and extend both upwardly and downwardly. In addition, while the lower retainer member 142 is shown and described as including the annular channel 149, the lower retainer member 142 may instead include one or more discrete openings (not shown) for receiving the corresponding fingers or pins, which may improve the engagement of the pins 146 with the lower retainer member 142 and increase the retention between the pins 146 and the lower retainer member 142 once the upper and lower retainer members 140, 142 are connected to each other. Employing the channel 149 instead of the discrete openings eliminates the need to circumferential align the upper and lower retainer members 140, 142 prior to connecting the upper and lower retainer members 140, 142 to one another.
The plurality of pins 146 of the upper retainer member 140 of the guard assembly 130 are configured to be received through the plurality of openings 131, 133, 135, 137 in the respective ring portions 132a, 134a, 136a, 138a of the first, second, third, and fourth guard members 132, 134, 136, 138, respectively. Receipt of the plurality of pins 146 of the upper retainer member 140 of the guard assembly 130 through the plurality of openings 131, 133, 135, 137 in the respective first, second, third, and fourth guard members 132, 134, 136, 138 and subsequent attachment of the lower retainer member 142 to the upper retainer member 140 secures the first, second, third, and fourth guard members 132, 134, 136, 138 relative to one another. The upper and lower retainer members 140, 142 of the guard assembly 130 also secure the guard assembly 130 and seal assembly 170 the centering mechanism 150.
With particular reference to
As described in the '477 publication, the plurality of spokes 154 of the centering mechanism 150 each include a free end 154a configured to engage an inner wall 114a (
Alternatively, the centering mechanism may include a bellows or otherwise be configured to maintain the valve assembly 120 centered within the instrument valve housing 110.
Referring again to
The septum seal 174 of the seal member 170 is formed of an elastic material, e.g., rubber, and defines a central opening 173. In embodiments, the septum seal 174 may include one or more fabric layers. The septum seal 174 is configured to provide a seal around an outer surface of a surgical instrument passing through the valve assembly 120. A surface 174a of the septum seal 174 defining the central opening 173 may be beveled or otherwise configured to facilitate reception of the surgical instrument through the central opening 173 in the septum seal 174. The septum seal 174 further defines a plurality of openings 175 corresponding to the pins 146 extending from the upper retainer member 140 of the guard assembly 130.
With particular reference to
In an assembled configuration, the seal assembly 170, including the guard assembly 130, is received within the annular ring 152 of the centering mechanism 150. More particularly, the tabs 156 (
During a surgical procedure utilizing cannula 100, an instrument (not shown) is introduced into the instrument valve housing 110 through the longitudinal passage 113 in the first and second housing sections 112, 114. As described above, the distal end of the instrument engages the first and second flap portions 132b, 134b of the respective first and second guard members 132, 134. The first and second flap portions 132b, 134b flex downward into contact with the third and fourth flap portions 136b, 138b of the respective third and fourth guard members 136, 138. The first, second, third and fourth flap portions 132b, 134b, 136b, 138b flex into contact with the septum seal 174 of the seal member 170 to cause the central opening 173 of the septum seal 174 to open to accommodate passage of the surgical instrument through the septum seal 174. The first, second, third, and fourth guard members 132, 134, 136, 138 of the guard assembly 130 minimize damage to the seal member 170 during insertion of an instrument through the valve assembly 120.
The first, second, third, and fourth guard members 132, 134, 136, 138 of the guard assembly 130 operate to protect the septum seal 174 of the seal assembly 170 from tearing or other damage as a surgical instrument is received through the seal assembly 170. Additionally, the guard assembly 130 may prevent inversion of the septum seal 174 as the surgical instrument is retracted through the septum seal 174.
