Description

BACKGROUND

1. Technical Description

The present disclosure is directed to a stomal support device and to method for performing an ostomy procedure and, more particularly, to a modular stomal support device and a method of use thereof.

2. Background of Related Art

During an ostomy procedure, a portion of an internal body vessel, such as the intestine or colon, is exteriorized to form a stoma. Stomas may be created in conjunction with an ostomy procedure by securing a bisected portion of the internal body vessel to the abdominal wall to provide internal access into the internal body vessel for collecting fecal matter. Ostomy surgery is sometimes performed on an emergency basis due to diverticulitis, trauma, radiation complications, volvulus, necrotic bowel, bowel perforation, etc. An ostomy may be temporary to allow for healing of the bowel or a decrease of inflammation at a surgical site. In some instances, an ostomy may be permanent.

In ostomy procedures, the internal body vessel is secured to the abdominal wall and/or cutaneous tissue of the abdomen. Securing the internal body vessel to the abdominal wall and/or the cutaneous tissue of the abdomen keeps the stoma in the desired location and prevents it from withdrawing back into the abdominal cavity. Typically, a colostomy bag is connected to the stoma site with an adhesive to collect waste materials from the internal body vessel. Although a stoma has no sensory nerve endings and is insensitive to pain, several complications can result at the stoma site where the colostomy bag is secured, such as leaks, skin irritation, infection, etc. As such, the condition of the stoma must be assessed regularly.

Thus, there is a continuing need in the medical arts for an alternative mechanism for collecting fecal matter or waste material from an internal body vessel that overcomes the above disadvantages and can improve the quality of life of patients requiring ostomy.

DETAILED DESCRIPTION OF EMBODIMENTS

The presently disclosed stomal device will now be described in detail with reference to the drawings in which like reference numerals designate identical or corresponding elements in each of the several views. 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.

With reference to FIGS. 1 and 2, the presently disclosed stomal device is shown generally as a stomal device 100 and is configured for use in, e.g., loop colostomy, in which, a part of the colon is lifted above skin level and held in place with the stomal device 100. However, it is also contemplated that the stomal device 100 may be used in other surgical procedures such as, e.g., ileostomy or urostomy. The stomal device 100 includes a rod 110 and first and second anchoring portions 120, 122 detachably coupled to the rod 110. The first and second anchoring portions 120, 122 may be transversely connected to respective opposing first and second ends 112, 114 of the rod 110. For example, the first and second ends 112, 114 of the rod 110 may have respective dove-tail connections 112a, 114a that frictionally mate with respective dove-tail connections 120a, 122a (FIG. 3) of the first and second anchoring portions 120, 122. Under such a configuration, the first and second anchoring portions 120, 122 are frictionally secured with the rod 110 to provide a detachable connection with the rod 110.

With reference to FIG. 3, the first and second anchoring portions 120, 122 may include padding portions 126 formed of, e.g., foam, configured to engage the abdominal wall or the skin of the patient. The padding portions 126 may reduce concentration of weight or stress on the abdominal wall or the skin when the stomal device 100 is supported on the abdominal wall or the skin. It is contemplated that the padding portions 126 may be disposed over the entire contacting surfaces 120b, 122b (FIG. 2) of the respective first and second anchoring portions 120, 122 or, as shown, just on selected portions of the contacting surfaces 120b, 122b.

In embodiments, the rod 110 may have any suitable cross-sectional shape such as, e.g., a semi-circular, circular, square, rectangular, or the like. In some embodiments, the rod 110 may be formed from pliable, semi-rigid, or rigid material, such as a plastic, a polymer, a metal, or the like. In certain embodiments, each padding portion 126 may include an adhesive (not shown) in the form of, e.g., a flat sheet, sticker, tape, or the like, to facilitate securement of the stomal device 100 on abdominal wall or the skin of the patient. In embodiments, the adhesive may include any type of biocompatible adhesive (e.g., glue). In some embodiments, the contacting surfaces 120b, 122b (FIG. 2) of the first and second anchoring portions 120, 122 may optionally include an adhesive coating in lieu of the adhesive on the padding portion 126.

With reference now to FIGS. 4 and 5, a stomal device in accordance with another embodiment of the present disclosure is shown generally as a stomal device 200. The stomal device 200 is substantially identical to the stomal device 100, and thus, identical parts in the stomal device 200 will not be described herein to avoid obscuring the present disclosure in unnecessary detail. The stomal device 200 includes a rod 210 and first and second anchoring portions 220, 222 detachably coupled to the rod 210. The rod 210 may be identical to the rod 110 (FIG. 1), and thus, may be interchangeably used. The first and second anchoring portions 220, 222 each have an arcuate profile defining a concavity. The rod 210 includes opposing first and second ends 212, 214 configured to detachably engage the respective first and second anchoring portions 220, 222. For example, the first and second ends 212, 214 of the rod 210 have respective dove-tail connections 212a, 214a that frictionally mate with respective dove-tail connections 220a, 222a of the first and second anchoring portions 220, 222. Under such a configuration, the first and second anchoring portions 220, 222 are frictionally secured with the rod 110.

The rod 210 of the stomal device 200 may be identical to the rod 110 of the stomal device 100. Under such a configuration, the first and second anchoring portions 220, 222 may be used interchangeably with the first and second anchoring portions 120, 122. Due to the concavity of the first and second anchoring portions 220, 222, the first and second anchoring portions 220, 222 contact different portions of the abdominal wall or the skin of the patient when connected to the rod 110 or the rod 210, compared to the first and second anchoring portions 120, 122. Thus, during prolonged use of the stomal device 100, trauma or stress to the abdominal wall or the skin may be reduced when the first and second anchoring portions 120, 122 are replaced with the first and second anchoring portions 220, 222.

With reference now to FIGS. 6 and 7, a stomal device in accordance with another embodiment of the present disclosure is shown generally as a stomal device 300. The stomal device 300 is substantially identical to the stomal device 200, and thus, identical parts in the stomal device 300 will not be described herein to avoid obscuring the present disclosure in unnecessary detail. The stomal device 300 includes a rod 310 and first and second anchoring portions 320, 322 detachably coupled to the rod 310. The first and second anchoring portions 320, 322 each have an arcuate profile defining a convexity. The rod 310 includes opposing first and second ends 312, 314 configured to detachably engage respective first and second anchoring portions 320, 322. For example, the first and second ends 312, 314 of the rod 310 may have respective dove-tail connections 312a, 314a that frictionally mate with respective dove-tail connections 320a, 322a of the first and second anchoring portions 320, 322. Under such a configuration, the first and second anchoring portions 320, 322 are frictionally secured with the rod 310. The rod 310 of the stomal device 300 may be identical to the rod 110 of the stomal device 100. Under such a configuration, the first and second anchoring portions 320, 322 may be used interchangeably with the first and second anchoring portions 120, 122 of the stomal device 100. Due to the convexity of the first and second anchoring portions 320, 322, the first and second anchoring portions 320, 322 contact different portions of the abdominal wall or the skin of the patient when connected to the rod 110 or the rod 310, compared to the first and second anchoring portions 120, 220 and 122, 222. Thus, during prolonged use of the stomal device 100, trauma or stress to the abdominal wall or the skin may be reduced by replacing the first and second anchoring portions 120, 220 and 122, 222 with the first and second anchoring portions 320, 322.

With reference now to FIG. 8, a stomal device in accordance with another embodiment of the present disclosure is shown generally as a stomal device 400. The stomal device 400 is substantially identical to the stomal device 100, and thus, identical parts in the stomal device 400 will not be described herein to avoid obscuring the present disclosure in unnecessary detail. The stomal device 400 includes a rod 410 and first and second anchoring portions 420, 422 detachably coupled to the rod 410. In particular, the first and second anchoring portions 420, 422 each have a length L2 larger than a length L₁ of the first and second anchoring portions 120, 122 of the stomal device 100. The rod 410 of the stomal device 400 may be identical to the rod 110 of the stomal device 100. Under such a configuration, the first and second anchoring portions 420, 422 may be used interchangeably with the first and second anchoring portions 120, 122 of the stomal device 100. Due to the difference in length L2 of the first and second anchoring portions 420, 422 and the length L₁ (FIG. 1) of the first and second anchoring portions 120, 122, the first and second anchoring portions 420, 422 contact different portions of the abdominal wall or the skin of the patient when attached to the rod 110 or the rod 410, compared to the first and second anchoring portions 120, 220, 320 and 122, 222, 322. Thus, trauma or stress to the abdominal wall or the skin during prolonged use of the stomal device 100 may be reduced by periodically replacing the first and second anchoring portions 120, 122 with the first and second anchoring portions 420, 422.

With reference now to FIG. 9, the stomal device 100 may be provided in a kit 500 to enable the clinician to interchangeably utilize different first and second anchoring portions 120, 220, 320, 420 and 122, 222, 322, 422. Various first and second anchor portions 120, 220, 320, 420 and 122, 222, 322, 422 may support the rod 110 on different parts of the abdominal wall or the skin of the patient, thereby reducing stress and trauma to the abdominal wall or the skin in prolonged use of the rod 110. In addition, the stomal devices 100 may also reduce infection by enabling the clinician to replace the first and second anchor portions 120, 220, 320, 420 and 122, 222, 322, 422 during prolonged use of the stomal devices 100, 200, 300, 400. In this manner, sores and wounds on the skin at the support site may be reduced.

With reference to FIGS. 10-12, in use, for example, in a loop ostomy procedure (e.g., a diverting sigmoid loop colostomy, loop ileostomy, etc.), an incision is made into a patient's abdomen at an incision site “I.” A portion or loop “L” of the body vessel is pulled outwardly through the incision site “I” such that the loop “L” extends out of the patient's abdomen. The body vessel may include the bowel, e.g., small or large intestine, colon, or rectum. In order to inhibit the loop “L” from receding through the incision site “I” and back into the abdominal cavity, the rod 110 is positioned centrally between the loop “L” and the patient's abdomen (e.g., at skin level).

The tissue contacting surfaces of the padding portion 126 of the first and second anchoring portions 120, 122 are brought into contact with the patient's abdomen adjacent the incision site “I” to secure the rod 110 to the patient's abdomen. With the rod 110 positioned between the loop “L” and the first and second ends 112, 114 (FIG. 1) of the rod 110 supported on the abdominal wall, the loop “L” of the body vessel is inhibited from receding back into the abdominal cavity. Thereafter, a first incision is made into the body vessel to create a first opening O₁ therein. For example, the first opening O₁ may be formed in the upstream portion of the large intestine. A second incision is made into the body vessel to create a second opening O₂ therein. The second opening O₂ may be formed within the body vessel, such as, e.g., the downstream portion of the intestine. At this time, the first and second anchoring portions 120, 122 are detachably connected to the rod 110 in order to support the rod 110 on the skin. The first and second openings O₁, O₂ define the stoma “ST.” Each of the first and second openings O₁, O₂ is then affixed or sutured to the abdomen (e.g., at skin level) using one or more sutures “S” or adhesive (not shown). At this time, the clinician may attach a catheter (not shown) and/or a colostomy bag (not shown) to the stoma “ST”, as needed. For example, as the patient undergoes normal digestive processes (e.g., excretion), digestive waste flows from the first opening O₁ of the stoma (e.g., the upstream portion of the intestine) through a first tube (not shown) and into the colostomy bag. A second tube (not shown) may separate the second opening O₂ of the stoma “ST” from the first opening O₁ of the stoma “ST,” e.g., to keep the downstream portion of the intestine clean, and/or to allow for healing of the intestine. As such, no fluid can flow from the second tube of the catheter into the downstream portion of the intestine.

In order to inhibit possible skin irritation at the stoma “ST” after a prolonged use of the stomal rod 110 and the first and second anchoring portions 120, 122, the first and second anchoring portions 120, 122 may be replaced with other first and second anchoring portions 220, 320, 420 and 222, 322, 422 such that different parts of the abdominal wall or the skin engage the first and second anchoring portions 220, 320, 420 and 222, 322, 422 and support the rod 110. As discussed hereinabove, the first and second anchoring portions 120, 220, 320, 420 and 122, 222, 322, 422 may include padding materials 126, 226, 326, 426 which may include adhesive to further facilitate securement of the rod 110 to the skin. For example, by placing the padding materials 126, 226, 326, 426 on various locations on the abdominal wall or the skin of the patient relative to the original site of attachment, formation of sores or wounds may be reduced.

Persons skilled in the art will understand that the structures and methods specifically described herein and shown in the accompanying figures are non-limiting exemplary embodiments, and that the description, disclosure, and figures should be construed merely as exemplary of particular embodiments. It is to be understood, therefore, that the present disclosure is not limited to the precise embodiments described, and that various other changes and modifications may be effected by one skilled in the art without departing from the scope or spirit of the disclosure. For example, while dove-tail configuration is used to detachably connect the first and second anchoring portions 120, 220, 320, 420 and 122, 222, 322, 422 to the rods 110, 210, 310, 410, it is also contemplated that other structures such as, e.g., snap-fit configuration, may be used.

Additionally, the elements and features shown or described in connection with certain embodiments may be combined with the elements and features of certain other embodiments without departing from the scope of the present disclosure, and that such modifications and variations are also included within the scope of the present disclosure.
