Definitions
- the present invention is directed to an anchor assembly for retaining a medical instrument within an anatomical cavity, wherein the anchor assembly comprises a mechanical attachment of an inflatable member to the exterior of the medical instrument.
- the mechanical attachment eliminates or at least minimizes the reliance on adhesive and other conventional types of connections, thereby greatly reducing the assembling and manufacturing costs, while eliminating or significantly reducing the failure or inadvertent detachment of the inflatable member from its operative position on the instrument.
- anchoring devices on medical instruments, in order to maintain the instrument on the interior of a body cavity or in a predetermined location relative to other organs of the body, is well known.
- One prevalent category of anchoring devices includes the use of an inflatable "balloon" or like member formed of an expandable material and secured to an exterior portion of the instrument with which it is associated.
- Examples of medical instruments incorporating such inflatable anchoring devices include trocars, which are used in laparoscopic or endoscopic surgery, and in particular, the cannula portion of the trocar, as well as retention catheters.
- a flexible or resilient body portion has an elongated inflating lumen which directs fluid (e.g., gas) under pressure into an interior the inflatable balloon or like structure. Upon inflation, the balloon will extend radially outward so as to effectively retain the catheter in the intended position.
- fluid e.g., gas
- trocar structures are used in minimally invasive surgical procedures. In use, a cannula portion of the trocar enters a body cavity and is effectively retained or "anchored" into an intended position by subjecting the interior of the anchoring balloon to pressurized fluid.
- the elastic material from which the inflatable balloons or like members were formed was a rubber or latex material. As such, the degree of pressurization of the inflating fluid was maintained within certain acceptable limits.
- the inflatable balloons or like structures have been formed of a plastic material including, but not limited to, polyurethane, polyvinyl chloride and various copolymers thereof. It was soon discovered that balloons formed from the aforementioned types of plastic materials require higher inflation pressures than conventional latex balloons. While the inflating fluid could easily be supplied to the interior of the balloon or other inflatable retention device at an increased pressure, other disadvantages or problems associated therewith developed.
- the structural features associated with the attachment or securement of the inflatable anchors to the exterior of the medical instrument are recognized as being problematic.
- the aforementioned disadvantages are primarily associated with failure or malfunctioning of the inflatable member by virtue of them becoming detached when expanded or inflated, not unlike the "blow-out" of a tire.
- a variety of different techniques, wrapping or winding structures, etc. were developed in an attempt to provide a reliable means of attaching an inflatable member to the cannula portion of a trocar, while not overly complicating the manufacturing process for such anchoring devices .
- Known structures associated with the attachment of inflation anchors or like expandable structures typically include the use of adhesives, molding and/or heat sealing techniques, which may used independently or in combination with one another.
- an inflatable anchoring structure associated with known, commercially available trocar assemblies utilizes an adhesive securement in combination with a wrapping or binding of wound suturing material. The suturing material is applied to opposite ends or other appropriate portions of the inflatable retention device in order to maintain its secured engagement on the exterior of the cannula portion of the trocar or other type of instrument.
- any such improved anchoring assembly would ideally include the attachment of an inflatable member to an instrument in a manner capable of consistently withstanding inflating gases supplied at commonly used or increased pressures.
- the present invention is intended to address these and other needs which remain in the art and is directed to an anchoring assembly of the type typically utilized to maintain the cannula portion of trocars, retention catheters and/or other medical instruments in a preferred or intended location on the interior of a body cavity or in retaining engagement with one or more organs within the body cavity.
- the anchoring assembly of the present invention is of the inflatable type typically comprising an inflatable "balloon", bag or like member, capable of being selectively disposed between an outwardly extending, expanded position and a collapsed position.
- the medical instrument associated with the anchor assembly of the present invention may, therefore, be maintained in an intended position within a body cavity by selectively orienting an inflatable member into the expanded or inflated position.
- the anchor assembly of the present invention is structured to overcome many of the disadvantages and problems associated with the failure of known or conventional inflatable anchoring or retaining devices by mechanically securing the inflatable member to an exterior of the instrument with which it is associated.
- the anchoring assembly of the present invention comprises a mounting assembly secured to an exterior portion of the cannula or other instrument.
- the mounting assembly includes a first mounting member and a second mounting member both disposed in overlying, at least partially surrounding relation to exterior surface portions of the cannula or instrument.
- a base is also secured in overlying relation to an exterior surface the instrument on which the anchoring assembly is mounted. The base is disposed in adjacent but spaced relation to the mounting assembly including each of the first and second mounting members.
- the base is disposed in underlying relation to the inflatable member and is positioned and structured to substantially confront interior surface portions of the inflatable member, such as when the inflatable member is in the aforementioned collapsed position.
- the base and the inflatable member may be considered to have a generally similar or corresponding overall configuration at least to the extent of being annularly formed so as to extend in surrounding, overlying relation to an exterior portion of the associated instrument. Such an annular configuration of at least the inflatable member facilitates the outward, radially oriented disposition of the inflatable member when in its expanded position.
- the base may comprise a bushing or like structure having a closed, continuous configuration and is cooperatively disposed and structured to facilitate the mechanical attachment of the inflatable member in its intended operative position.
- the anchor assembly comprises a first mounting member and a second mounting member.
- the base is positioned adjacent and in spaced relation to each of the first and second mounting members by virtue of its disposition there between.
- a predetermined spacing exists between the base and the mounting assembly. This predetermined spacing is preferably defined by two retaining spaces, each disposed or formed between different ones of the first and second mounting members and a corresponding portion of the base.
- the inflatable member includes a retaining portion formed thereon or connected thereto.
- the retaining portion preferably includes at least two retaining segments which may be disposed or defined by peripheral segments of opposite ends of the inflatable member. Each of the retaining segments are correspondingly disposed and configured to be received within different on.es of the aforementioned retaining spaces defined between the base and each of the first and second mounting members .
- the cooperative structuring of the first and second mounting members and the base, as well as their disposition relative to one another, facilitates the secured retention of the retaining segments by the mechanical locking and sealing thereof in a sandwiched or at least partially compressed orientation within corresponding ones of the retaining spaces.
- a reliable securement of the inflatable member to the exterior of the trocar cannula or other medical instrument is accomplished using primarily, if not exclusively, a mechanical attachment as versus the use of adhesive, heat sealing techniques or exterior binding with wound suture, thread, cord, or like material.

- Figure 2 is a longitudinal sectional view in partial cutaway and phantom showing structural details of at least one preferred embodiment of the anchor assembly of the present invention.
- Figure 3 is a sectional view in partial cutaway showing structural details of a preferred embodiment of the anchor assembly of the present invention including an inflatable member, as disclosed in Figures 1 and 2.
- Figure 4 is a sectional view in partial cutaway of the embodiment of Figure 3, absent the inflatable member.
- Figure 5 is a longitudinal sectional view in partial cutaway of yet another preferred embodiment of the anchor assembly of the present invention.
- Figure 6 is a perspective view of a bushing-like base associated with the embodiment of Figure 5.
- Figure 7 is a longitudinal sectional view of the embodiment of Figure 6.
- the present invention is directed to an anchor assembly, generally indicated as 10, structured to be secured to a trocar assembly, generally indicated as 12, or to another type of medical instrument.
- the instruments 12 are of the type intended to be maintained in a predetermined position or orientation within a body cavity. Therefore, while the anchor assembly 10 is described herein as being mounted about the exterior of a cannula portion 14 of the trocar assembly 12, the anchor assembly 10 of the present invention could be utilized with a variety of medical instruments including, but not limited to a retention catheter or like device.
- the anchor assembly 10 is of the type which is inflatable by means of directing pressurized fluid thereto through an inlet port generally indicated as 16.
- the anchor assembly 10 of the present invention includes an inflatable member 18 selectively disposed between a collapsed position, as represented in solid lines in Figures 1, 2 and 3, and an inflated, expanded position as represented in phantom lines in Figure 2.
- the inflatable member 18 When in its expanded position, the inflatable member 18 extends radially outward from the exterior of the cannula 14.
- the inflatable member 18, whether in its collapsed or expanded position comprises a substantially annular configuration disposed in surrounding relation to the exterior portion of the trocar 12 and cannula 14 associated therewith. Venting of the inflatable member 18 or removal of the inflating fluid from the interior 19 can be accomplished by manipulation of appropriate valving structure associated with the inlet 16 or other portions of the trocar body 13, as is well known in the art.
- One structural feature of the anchor assembly 10 of the present invention is the mechanical securement of the inflatable member 18 to the medical instrument 12 in a manner which is safe, reliable, cost effective and otherwise expeditious from a manufacturing standpoint.
- the term "mechanical” is meant to be descriptive, in its broadest sense, of securing the inflatable member 18 to the medical instrument 12 in a manner which does not primarily rely on adhesive, heat sealing, exterior binding, or other conventional means of attachment which are currently utilized in the manufacture of medical instruments of this type.
- the inflatable member 18 is mechanically secured to the exterior cannula 14 or other medical instrument, in a manner to be described in greater detail hereinafter, the use of adhesive or other mounting or attachment devices, compositions or methods may be utilized at least to a minimal extent to maintain certain other components of the anchoring assembly 10 in their intended, operative position.
- the various preferred embodiments of the anchor assembly 10 of the present invention include the provision of a mounting assembly, indicated generally as 20 in Figure 1.
- the mounting assembly 20 includes a first mounting member 22 and a second mounting member 24 disposed on the exterior of the medical instrument, such as the cannula 14, by frictional engagement with the exterior surface thereof or by other appropriate means, which will also be described hereinafter.
- the first mounting member 22 is preferably in the form of a sleeve or like structure having an elongated tubular configuration.
- the length of the first mounting member 22 may vary, but preferably, extends from a location which is inwardly spaced from the distal end or extremity 25 of the cannula 14 to a location generally adjacent or contiguous to the trocar housing
- a sealing device such as, but not limited to, an "O-ring" or like member 27 may be utilized to provide a substantially fluid-tight seal between the proximal end 22' of the first support member 22 and the exterior surface of the cannula
- the O-ring 27 may be replaced by an adhesive or other sealant material or other appropriate structure for maintaining a fluid tight seal between the proximal 22' and the exterior surface of the cannula 14.
- the second mounting member 24 is preferably in the form of an annular collar or end cap segment having oppositely disposed open ends.
- the second mounting member 22 is disposed substantially adjacent and in inwardly spaced relation to the open distal end or extremity 25 of the cannula 14.
- the base 28 is directly associated with the secure, mechanical mounting of the inflatable member 18 due at least in part to the predetermined disposition thereof relative to the mounting assembly 20.
- the base 28 is preferably in the form of an annular bushing disposed in surrounding relation about the exterior surface of the cannula 14.
- the annular base 28 includes an inner diameter or dimension that is at least minimally larger than the outer diameter or corresponding dimension of the cannula 14. As such, the base 28 is not fixedly secured to the cannula 14 but rather, is at least minimally spaced from the exterior surface of the cannula 14. This relative dimensioning will facilitate the assembly of the first and second mounting members 22 and 24 and the inflatable member 18 in their intended operative position, as set forth in greater detail hereinafter.
- the base 28 is positioned on the interior the inflatable member 18 and substantially between the inflatable member 18 and the cannula 14. Being so positioned, the interior of the inflatable member 18 is oriented in confronting relation with the exterior surface of the base 28, especially when the inflatable member 18 is in its collapsed position, as best shown in Figure 2. As is also represented, when the inflatable member 18 is in its outwardly expanded or inflated position it is disposed in outwardly spaced and surrounding relation to the base 28 and the cannula 14.
- the first and second mounting members 22 and 24 are mechanically secured to the exterior of the medical instrument 12 or cannula 14 in spaced relation to one another.
- This relative orientation allows for the positioning of the base 28 between and adjacent to both the first mounting member 22 and the second mounting member 24, albeit in spaced relation thereto, as best shown in Figures 3 and 4.
- This "predetermined spacing" between the base 28 and the mounting members 22 and 24, is more specifically defined by two retaining spaces, generally indicated as 30 and 32.
- each of the retaining spaces 30 and 32 are disposed between and at least partially defined by opposite ends of the base 28, as at 28' and 28" and the respective ends of the first mounting member 22, as at 22', and the second mounting member 24, as at 24'.
- each of the retaining spaces 30 and 32 has an overall, annular configuration extending substantially continuously about the exterior of the cannula 14.
- the mechanical mounting of the inflatable member 18 in its intended operative position on the exterior of the medical instrument 12 is further accomplished through the provision of a retaining portion integrally or otherwise fixedly secured to the inflating member 18.
- the retaining portion comprises at least one, but preferably, two retaining segments 40 and 42 each preferably secured to opposite peripheral ends or extremities of the inflatable member 18, as shown in both Figures 2 and 3.
- Each of the retaining segments 40 and 42 are disposed, dimensioned and/or configured to be received within a corresponding one of the retaining spaces 30 and 32.
- the retaining segments 40 and 42 are thereby securely "gripped" within the retaining spaces 30 and 32, by virtue of being compressed between correspondingly positioned portions of the respective mounting members 22 and 24 and the corresponding ends 28' and 28" of the base 28.
- the retaining segments 40 and 42 are formed of a compressible material and may have an overall greater dimension than the corresponding retaining spaces 30 and 32 in which they are respectfully received.
- Each of the retaining spaces 30 and 32 include an opening 44 disposed in communication with an exterior of the medical instrument 12, as best shown in Figures 3 and 4. Therefore, and as set forth above, the corresponding ends 28' and 28" of the base 28 are cooperatively dimensioned, disposed and configured with corresponding portions 22' and 24' of the first and second mounting member so as to not only define the retaining spaces 30 and 32, but also to define each of the openings 44 to have a much lesser dimension than the corresponding retaining spaces 30 and 32.
- the retaining segments 40 and 42 being of a larger dimension than the openings 44, cannot pass there through upon the inflatable member 18 being inflated into its expanded position, as represented in phantom in Figure 2.
- the retaining segments 40 and 42 are thereby mechanically secured within the retaining spaces 30 and 32 whether the inflatable member 18 is in the collapsed position or the expanded position.
- FIG. 3 and 4 Yet another structural feature of the present invention, as represented in Figures 3 and 4 comprises the ends 28' and 28" of the base, as well as the correspondingly positioned portions 22' and 24' of the first and second mounting members 22 and 24, having inwardly directed flanges 50 and 52 respectively. Accordingly, a pair of the flanges 50 and 52 are associated with each of the retaining spaces 30 and 32 and are provided to further restrict the transverse dimension of each of the openings 44. Therefore, while the dimension of the openings 44 are sufficient to allow passage of a connecting segment or link 54 of the inflatable member 18 there through, the dimension of each of the openings 44 are sufficiently reduced to prevent the passage there through of the retaining segments 40 and 42.
- the various operative components comprise a substantially circular or annular configuration. More specifically, the various operative components, including the first and second mounting members 22 and 24, the base 28, the inflatable member 18, the retaining spaces 30 and 32, the retaining segments 40 and 42 and the openings 44, all include a substantially continuous configuration as should be evident from the observance of Figures 1 and 2.
- the positioning of the inflatable member 18 into its expanded position is accomplished by directing a flow of gas or other appropriate fluid, under pressure, into the "interior" 19 of the inflatable member 18.
- the inflating fluid is supplied through the inlet 16 and travels along a path of fluid flow which may comprise one or more channels or passageways 60 formed between the cannula 14 and interior surface of the first mounting member 22.
- the one or more channels 60 are disposed beneath the retaining segment 40, disposed adjacent to the first mounting member 22, and into one or more outlet ports 62.
- the outlet port(s) 62 passes through the base 28 and communicates with the interior 19 of the inflatable member 18.
- At least one embodiment of the present invention may comprise a one or more channels or passages 60 that are disposed in fluid communication with one or more outlets 62 for delivery of the inflating fluid into the interior of the inflatable member 18.
- one or more of the channels or passages 60 are integrally formed so as to be recessed into the exterior surface of the cannula 14. It is emphasized that the length of the passage (s) 60 may vary and extend between the point of communication with the inlet 16 and the point of delivery with outlet 62 into the interior 19. Alternatively, the one or more passages 60 may extend along only a portion of the length of the cannula, such as in the area of and beneath the retaining segment 40.
- FIG. 5 Yet another preferred embodiment of the present invention is disclosed in figures 5 through 7 and relates to a path of fluid flow defined by one or more passages 60' extending beneath and beyond the retaining segment 40 and into communication with a peripheral channel or groove 65.
- the peripheral groove 65 is formed on the exterior of the cannula 14 and is disposed in direct fluid communication with a plurality of inlets 62 ' .
- there are at least two inlets 62' but in is emphasized that the number of inlets' 62' may vary.
- the inlets 62' are formed in a sidewall of the base 28 in a position to direct the inflating fluid from the groove 65 into the interior 19 of the inflatable member 18.
- the existence a path of fluid flow, including the one or more passages 60', is preferably formed in the exterior surface of the cannula 14, so as to allow the inflating fluid to bypass the potentially sealing effect of the retaining segment 40 against the exterior surface of the cannula 14.
- the location of the inlet 62 may be located at different positions along the length of the bushing-like base 28.
- the one or more inlets 62' are substantially centered between opposite ends 28' and 28" of the base 28.
- the one or more inlets 62 are located substantially adjacent a proximal end 28' of the base 28.
- the first mounting member 22 is positioned in overlying, surrounding and substantially covering relation to the exterior of the cannula 14.
- the first mounting member 22 preferably, but not necessarily, extends from the fluid inlet 16, adjacent the body 13 of the instrument 12, to the inflatable member 18, as best shown in Figure 1.
- the base 28 with the inflatable member 18 disposed thereon is passed over the distal extremity 25 and forced axially inward towards the first mounting member 22.
- the retaining segment 40 is thereby compressed and mechanically captured, gripped and secured within the retaining space 30.
- the flanges 50 and 52 associated with the retaining space 30 serve to define the corresponding opening 44.
- the connecting segment or link 54 being integrally or fixedly secured between the retaining segment 40 and the remainder of the inflatable member 18 passes through and may be at least partially compressed within the opening 44. Thereafter, the second mounting member or end cap 24 is passed over the distal extremity 25 and a predetermined, constant, axially directed force is exerted thereon, prior to it being fixedly attached, such as by using adhesive.
- This inwardly directed force serves to compress the end 22" against the O-ring, thereby facilitating its sealing engagement about the cannula 14.
- This constant axially directed compressive force also serves to compress the retaining segments 40 and 42 within the respective retaining spaces 30 and 32 facilitating the establishment of a secure, mechanical attachment of the inflatable member 18 to the instrument 12.
- the mounting of the inflatable member on the cannula 14 or other medical instrument 12 is primarily accomplished by the aforementioned mechanical attachment, comprising the compressed gripping engagement of the retaining segments 40 and 42 within the retaining spaces 30 and 32.
- an adhesive or other means of securement may be used to maintain certain of the operative components in their intended operative position. Therefore in at least one preferred embodiment, the second mounting member or end cap 24, subsequent to having the above noted axially directed force exerted thereon, is secured by an adhesive or other binding material to the exterior of the cannula 14 in its intended position, as shown in Figures 1 and 2.
- Yet another structural feature of the anchor assembly 10 of the present invention may include the provision of a securement assembly or member, generally indicated as 70.
- This securement member is fixedly or movably positioned along the exterior surface of the first mounting member 22. While a most preferred embodiment of the present invention has the exterior surface of the mounting member 22 having a somewhat smooth or non- interruptive exterior surface configuration, other configurations may include a stepped or ribbed configuration generally indicated as 72 which facilitates the placement of the securing member or assembly 70.
- the securement member 70 may be disposed in direct abutting engagement with the exterior surface or skin surrounding the entry site through which the cannula 14 as well at least the portion of the anchor assembly 10 passes. In doing so, the member 70 is preferably formed from a foam or at least semi-flexible or compressible material to resist damage to the exterior surface portions or skin surrounding the entry site.
- An anchor assembly structured to retain a medical instrument within a body cavity, said anchor assembly comprising: a) a mounting assembly disposed on an exterior of the medical instrument, b) a base disposed on the medical instrument in adjacent relation to said mounting assembly, c) an inflatable member formed of an elastomeric material and disposable in an expanded position and a collapsed position, and d) said inflatable member including a retaining portion mechanically secured between said base and said mounting assembly.
- An anchor assembly as recited in claim 1 wherein said expanded position comprises said inflatable member disposed radially outward from said base and an exterior of the medical instrument .
