Description

[Technical field]

[0001] The present disclosure relates to a closure. In particular, the present disclosure relates to a closure for a medical implant, and more particularly, to an ostomy implant. [Background technology]

[0002] (background) Ileostomy and colostomy are common surgeries that may be necessitated, for example, by malignancy or chronic intestinal inflammation. The surgery is called an ileostomy when the colon and rectum are removed, and a colostomy when only the rectum is removed. Similarly, abdominal nephrostomy is created when the bladder needs to be removed, for example, due to bladder cancer. In these surgeries, a fistula is created in the abdominal wall to which a segment of the intestine is connected.

[0003] An ileostomy is a fistula created by bringing an end or loop of the small intestine (ileum) above the surface of the skin or by a surgical procedure that creates an opening. Bowel waste passes out of the ileostomy and is collected in an external ostomy system that is placed next to the opening.

[0004] A colostomy is a surgical procedure that creates or creates a fistula in the large intestine (colon). An opening is created by drawing the healthy end of the colon through an incision in the anterior abdominal wall and suturing it in place. This opening, often in conjunction with an attached ostomy system, provides an alternative channel for feces to exit the body.

[0005] An ostomy pouching system is a medical device that provides a means for the collection of waste from a stoma. Conventional pouching systems usually consist of a collection pouch, a barrier on the skin, and a connection to the stoma itself, which is a part of the body that is bypassed to the skin.

[0006] As an alternative to traditional ostomy pouch systems, implant-based systems have been previously developed. The systems are based on percutaneous ostomy implants, which are anchored in the user's body and allow the serosal tissue of the intestinal compartment to be attached to the implant. Ostomy implants usually comprise a cylindrical body with an open end, to which a lid may be attached. When the lid is removed, the open end can be connected to an evacuation device such as an ostomy pouch. The solution allows the user to meet their needs at their own convenience, minimizing skin complications as well as discomfort, noise, and smell.

[0007] However, the lids currently available for ostomy implant-based solutions are associated with several inconveniences, e.g. related to ease of use, robustness, manufacturing complexity, etc.

[0008] The applicant's earlier international application WO2017 / 216302 discloses one variant of a cap for an ostomy implant. [Prior art documents] [Patent documents]

[0009] [Patent Document 1] International Publication No. 2017 / 216302 Summary of the Invention [Means for solving the problem]

[0010] (summary) The present disclosure relates to an improved closure for an ostomy implant, the closure comprising: a ring-shaped base piece adapted to engage the open end of the ostomy implant; a cap part adapted to fit inside the ring-shaped base part, the cap part being rotatable relative to the ring-shaped base part to lock and unlock the lid to the ostomy implant, the cap part having a through hole; A slider configured to be slid radially into a recess of a cap part in a closed configuration, the slider completely covering the through hole of the cap part, and slid radially out of the recess in an open configuration, the slider not covering the through hole of the cap part. Equipped with.

[0011] The ring-shaped base part is preferably configured to engage with a circumferential groove of the ostomy implant. By controlling the locking of the ring-shaped base part to the ostomy implant by means of a rotation of the cap part, a solution is obtained that is easy to use for the wearer. In particular, the cap part may be rotated by holding and rotating the slider when it is in the retracted position.

[0012] The slider may thus have a dual functionality in the lid assembly: in addition to acting as a handle for rotation of the cap to lock and unlock the lid to and from the ostomy implant, it may function as a retractable liquid-tight cover of the through hole of the cap part. In the closed configuration, which may also be referred to as the insertion position, the slider completely covers the through hole of the cap part. In the open configuration, which may also be referred to as the retracted position, the slider does not cover the through hole of the cap part. In this respect, "not covering" shall be interpreted as the slider not covering at least a part of the through hole, which means that there is a fluid connection between the inside and the outside of the stoma, which may be, for example, an ostomy pouch.

[0013] The cap part may include an upper gasket disposed around the through hole. Preferably, the upper gasket is arranged in the upper cap groove and projects upwardly from a recess in the cap part towards the slider. Preferably, the upper gasket and its upward projection are dimensioned such that the slider can slide over it to reach a closed configuration, the slider completely covering the through hole in the cap part, but at the same time the slider and the upper gasket form a liquid-tight seal in the closed configuration.

[0014] 1A-C show one embodiment of a lid of the present disclosure, comprising a ring-shaped base part (FIG. 1C), a cap part (FIG. 1B), and a slider (FIG. 1A). Preferably, the assembly does not have any loose parts and is therefore perceived by the user as one lid component.

[0015] The ring-shaped base piece may comprise a plurality of locking hooks configured to engage with the circumferential grooves of the ostomy implant. The cap piece may comprise a plurality of blocking elements corresponding to the plurality of locking hooks of the ring-shaped base piece. Preferably, the blocking elements are configured to block the plurality of locking hooks and not move out of the circumferential grooves of the ostomy implant when the cap is in the locked configuration.

[0016] The present disclosure further relates to a method of manufacturing a lid of the present disclosure, the method comprising: providing a ring-shaped base piece adapted to engage an open end of an ostomy implant; providing a cap part adapted to fit inside the ring-shaped base part, the cap part being rotatable relative to the ring-shaped base part to lock and unlock the lid to the ostomy implant, the cap part having a through hole; providing a slider configured to be slid radially into a recess in the cap part in a closed configuration, the slider completely covering the through hole in the cap part, and being slid radially out of the recess in an open configuration, the slider not covering the through hole in the cap part; Assembling a ring-shaped base part, a cap part, and a slider; Includes.

[0034] All drawings are illustrative and not limiting of the lid and method of manufacturing the lid of the present disclosure.

[0035] (Detailed Description) The present disclosure relates to a lid for an ostomy implant. The lid includes three parts, each of which may have an improved feature related to the operation of the lid.

[0036] The first part is a ring-shaped base part that is adapted to engage the open end of the ostomy implant.

[0037] The second part is a cap part adapted to fit inside the ring-shaped base part, the cap part being rotatable relative to the ring-shaped base part to lock and unlock the lid to the ostomy implant, the cap part having a through hole.

[0038] The third part is a slider that is configured to be slid radially into a recess in the cap part in a closed configuration, where the slider completely covers the through hole in the cap part, and is slid radially out of the recess in an open configuration, where the slider does not cover the through hole in the cap part.

[0039] The cap part is rotatable relative to the ring-shaped base part to lock and unlock the lid to and from the ostomy implant. Thus, rotation of the cap part relative to the ring-shaped base part (or vice versa) causes the lid to be attached to the implant. "Rotation" of the cap part and the ring-shaped base part shall be interpreted as a pivoting movement around the longitudinal axis of the ring-shaped base part and the cap part. These parts may have a generally cylindrical shape. The rotation / pivot may thus be considered as a rotation around the longitudinal axis of such a generally cylindrical shape. The cap part may thus be rotatable relative to the ring-shaped base part into a locked configuration, in which the lid cannot be removed from the ostomy implant, and into an unlocked configuration, in which the lid can be removed from the ostomy implant.

[0040] Figures 15A-C show the basic operation of the lid. In Figure 15A, the lid (100) is in a closed and locked position. In one embodiment, the cap part (300) is locked to the ring-shaped base part (400) when the slider (200) is in the closed configuration. In Figure 15B, the slider (200) has been slid to a retracted position. This can be done without any pivoting. The position in Figure 15B can be referred to as the locked and open configuration. This configuration can be used during the process during which waste material leaves the stoma. From the position in Figure 15B, the cap part (300) and the ring-shaped base part (400) can be rotated relative to each other to the position in Figure 15C, which shows the lid in an open and unlocked configuration, and the lid can be removed from the ostomy implant. Thus, in one embodiment of the lid (100) of the present disclosure, the cap part (300) is rotatable relative to the ring-shaped base part (400) when the slider (200) is in the open configuration. Preferably, the slider (200) is rotatably locked to the cap part (300), meaning that it can only be moved radially, i.e. between a closed position, in which the slider (200) completely covers the through hole (304) of the cap part (300), and an open configuration, in which the slider (200) does not cover at least a portion of the through hole (304) of the cap part (300). In the open configuration, the slider (200) protrudes outward and can thus be used as a lever or handle for rotating the cap part (300) relative to the ring-shaped base part (400). In one embodiment, the slider can be used to rotate the cap part relative to the ring-shaped base part in the open configuration to lock and unlock the lid to and from the ostomy implant.

[0041] In one embodiment, the cap part further comprises an upper gasket around the through hole, as shown in the example in Figure 5. The upper gasket (305) may be disposed within an upper cap groove, which is not visible in Figure 5. The upper gasket may protrude upward into a recess in the cap part. In one embodiment, the upper gasket protrudes less than 3 mm. Preferably, the slider and the upper gasket form a liquid-tight seal in the closed configuration.

[0042] In one embodiment, the slider includes two lower guide rails. The cap part may include two corresponding guide grooves for guiding the two lower guide rails. Figures 2 and 3 show an example of two lower guide rails (202) and two corresponding guide grooves (306).

[0043] The slider may be sized to extend across the diameter of the lid when assembled. The slider may thus be generally rectangular, but with slightly curved ends, to match the circumference of the lid. The slider may have a curved upper surface, with the curvature of this surface extending along the length of the slider. The recess in the cap component may thus be sized so that the slider can be slid through it.

[0044] By controlling the locking of the ring-shaped base part to the ostomy implant with the rotation of the cap part, a solution is obtained that is easy for the wearer to use. The ring-shaped base part may comprise a substantially cylindrical side wall (401) and a substantially flat bottom ring part (405), as shown in the embodiment of Fig. 10. The substantially flat bottom ring part may be a substantially flat annular structure. As will be understood by a person skilled in the art, the structure does not necessarily have to be completely flat.

[0045] The ring-shaped base piece comprises a number of locking hooks. The locking hooks may be configured to engage with circumferential grooves of the ostomy implant. An example of the locking hooks (404) can be seen in Fig. 8. Furthermore, in the example of Fig. 12, one can see how the locking hooks (404) engage with the circumferential grooves (501) of the ostomy implant (500). The locking configuration is represented by the locking hooks (404) being in position 404b.

[0046] Preferably, the locking hooks are made of a flexible and / or elastic material. The material may be, for example, a plastic material. One advantage of having an elastic material is that the locking hooks can have a default configuration in which they then do not engage with the circumferential groove of the ostomy implant. If a mechanism is used to push and hold the locking hooks in the circumferential groove of the ostomy implant in the locking configuration, the locking hooks can automatically return to their default configuration when the mechanism for pushing and holding the locking hooks in the circumferential groove is deactivated or released.

[0047] The locking hooks may be arranged on the inner edge of the bottom ring part. The locking hooks may have edges that point upwards and are slightly bent inwards. "Upwards" in this respect shall be interpreted as the longitudinal direction of the cylindrical base part towards the slider. "Inwards" refers to the radial direction of the cylindrical base part towards its centre. Thus, the locking hooks may be resilient pins with hooks configured to engage with circumferential grooves of the ostomy implant.

[0048] As will be appreciated by one of ordinary skill in the art, the implementation is not limited to a certain number of locking hooks, any suitable number of locking hooks may be used.

[0049] As mentioned, the lid may further comprise a mechanism for holding the locking hooks in the circumferential grooves of the ostomy implant in the locking configuration. Such a mechanism may be implemented by means of blocking elements on the cap part. Preferably, the blocking elements are distributed on the cap part and match the locking hooks. Thus, in one embodiment, the cap part comprises a number of blocking elements corresponding to the number of locking hooks of the ring-shaped base part. In the example of FIG. 12, it can be seen how the locking hooks (404) engage with the circumferential grooves (501) of the ostomy implant (500) at position 404b. The blocking elements (303) push the locking hooks (404) into the circumferential grooves (501) of the ostomy implant (500). In the example, the blocking elements (303) are arranged in a space (406) defined by the generally cylindrical side wall (401) of the ring-shaped base part (400) and the locking hooks (404). The blocking elements may be configured to block the locking hooks in the locked configuration so that they do not move from the circumferential groove of the ostomy implant. In the unlocked configuration, the locking hooks can move out of the circumferential groove of the ostomy implant in the unlocked configuration. This functionality can be obtained by having a blocking element with a curved shape that extends along an arc of the cap part. Alternatively, the blocking element can be described as having a spiral cross-sectional shape. When the cap part is rotated relative to the ring-shaped base part, i.e. also relative to the locking hooks of the ring-shaped part, the part of the blocking element that performs the blocking can be aligned with the locking hooks in the locked configuration. The blocking element can be arranged such that the distance of the blocking element relative to the center of the cap gradually increases along the curved shape. When the cap part is rotated towards the locked configuration, the blocking element can thus gradually push the locking hooks towards the circumferential groove of the ostomy implant. Embodiments of blocking element (309) can be seen, for example, in Figures 6, 7, and 13. The blocking element can have a proximal section (313) and a distal section (314), for example, as shown in Figure 6.The proximal section of the curved shape may block one of the locking hooks in the locked configuration, while the distal section of the curved shape allows the locking hook to move out of the circumferential groove of the ostomy implant in the unlocked configuration. The blocking element may be implemented as a chamfered surface (309) as shown in FIG. 7 and FIG. 13. Each chamfered surface may be a beveled edge. The overall shape of the chamfered surface may be described in one embodiment as the shape of a section of a spiral with a bevel, given that the blocking element may also have a shape such that the distance of the blocking element to the center of the cap gradually increases along the curved shape. The bevel may be oriented downward and inward within the cap part. Rotation of the cap part relative to the ring-shaped base part may lock the lid and control the alignment of the blocking elements and the locking hooks. As mentioned, this may be done by holding and pivoting a slider, which is rotatably locked to the cap part.

[0050] Each blocking element may further comprise a retracting element configured to guide and maintain the locking hook away from the circumferential groove of the ostomy implant in the unlocked configuration. When the cap part is rotated relative to the ring-shaped base part from the locked configuration to the unlocked configuration, the locking hook may at least partially fit into the circumferential groove of the ostomy implant. The retracting element may assist in actively moving the locking hook out of the circumferential groove when the cap part is pivoted to the unlocked configuration. FIG. 13 shows an embodiment of a blocking element (309) having a retracting element (315). In the figure, the locking hook (404) is guided to the retracted position by the retracting element (315) of the blocking element (309). When the lid is in the unlocked position, the retracting element (315) is located within the distal section (314) of the blocking element (309). The retraction element (315) has the form of a plate towards the center of the cap part with a beveled upper edge in the embodiment, which may be angled with respect to the center of the cap part such that in the unlocked configuration, it can guide the locking hook (404) to a retracted position behind the retraction element (315).

[0051] The cap part may further comprise, towards the ostomy implant, a lower gasket. The lower gasket and the upper circumferential edge part of the ostomy implant may form a liquid-tight connection in the locked configuration.

[0052] The ring-shaped base part and the cap part may comprise complementary guide elements, which are used for the rotation of the ring-shaped base part and the cap part relative to each other. In one embodiment, the complementary guide elements comprise one or more grooves provided on the cap part and one or more complementary protruding elements provided on the ring-shaped base part, which are arranged to extend into the one or more grooves, thereby allowing the cap part and the ring-shaped base part to rotate relative to each other. The cap part and the ring-shaped base part may be arranged such that as the cap part is rotated relative to the ring-shaped base part, the cap part is also moved axially relative to the ring-shaped base part. Such axial movement, caused by the rotation of the cap part relative to the ring-shaped part, may push the lower gasket facing the upper circumferential edge part of the ostomy implant against the upper circumferential edge part of the ostomy implant.

[0053] The ring-shaped base piece may further comprise a circumferential groove.

[0054] The present disclosure further relates to an ostomy implant assembly having a circumferential groove and a lid according to any one of the preceding claims.

[0055] The present disclosure further relates to a method of manufacturing a lid of the present disclosure, the method comprising: providing a ring-shaped base piece adapted to engage an open end of an ostomy implant; providing a cap part adapted to fit inside the ring-shaped base part, the cap part being rotatable relative to the ring-shaped base part to lock and unlock the lid to the ostomy implant, the cap part having a through hole; providing a slider configured to be slid radially into a recess in the cap part in a closed configuration, the slider completely covering the through hole in the cap part, and being slid radially out of the recess in an open configuration, the slider not covering the through hole in the cap part; Assembling a ring-shaped base part, a cap part, and a slider; Includes.

[0056] As will be understood by those skilled in the art, the method of manufacturing the lid of the present disclosure may be used to assemble the lid as described in the present disclosure, among others. The ring-shaped base part, the cap part, and the slider may be any suitable material, for example, a plastic material such as polyethylene, polypropylene, polycarbonate (PC), or polymethylmethacrylate (PMMA). However, others may also be used. The main parts of the ring-shaped base part, the cap part, and the slider may be molded thereby. If additional components are used, they may be mounted on the molded ring-shaped base part, the cap part, and the slider.

[0057] Detailed Description of the Drawings The present invention will now be described in more detail with reference to the accompanying drawings, which are examples of embodiments and are intended to illustrate some of the features of the lid of the present disclosure and are not to be construed as limiting the invention of the present disclosure.

The ring-shaped base piece (400) comprises a protruding element (403) provided on the inside of the side wall (401) of the ring-shaped base piece (400). The ring-shaped base piece (400) comprises several locking hooks (404) and a circumferential groove (402).

[0066] 9 shows a top view of an embodiment of a ring-shaped base piece (400). The ring-shaped base piece (400) comprises six locking hooks (404) evenly distributed on the inside of the ring-shaped base piece (400).

[0067] FIG. 10 shows a side view of an embodiment of a ring-shaped base piece (400) having a cylindrical side wall (401), a circumferential groove (402) and a bottom ring piece (405).

[0068] 11 shows a cross-sectional side view of an embodiment of a ring-shaped base piece (400). The ring-shaped base piece (400) has a protruding element (403) and a circumferential groove (402). The ring-shaped base piece (400) also shows two locking hooks (404).

[0069] 12 shows a further cross-sectional side view of an embodiment of a ring-shaped base part (400) engaging with a circumferential groove (501) of an ostomy implant (500). The ostomy implant (500) has an upper circumferential edge part (503). The locking hook (404) engages with the circumferential groove (501) of the ostomy implant (500) at position 404b. The blocking element (303) urges the locking hook (404) into the circumferential groove (501) of the ostomy implant (500). In an embodiment, the blocking element (303) is arranged in a space (406) defined by the substantially cylindrical side wall (401) of the ring-shaped base part (400) and the locking hook (404).

[0070] FIG. 13 shows an embodiment of a ring-shaped base part (400) and a cap part (300) in an unlocked configuration. One of the blocking elements (309) has a proximal section (313) and a distal section (314). The proximal section (313) may be adapted to maintain the locking hook (404) of the base part (400) in the circumferential groove of the ostomy implant in the locked configuration. However, FIG. 13 shows the unlocked configuration in which the distal section (314) is aligned with the locking hook (404). In an embodiment, the blocking element (309) further comprises a retracting element (315). The retracting element (315) has the shape of a plate towards the center of the cap part, in an embodiment, with a beveled upper edge. The plate may be angled with respect to the center of the cap part such that in the unlocked configuration, it may guide the locking hook (404) to a retracted position behind the retracting element (315).

[0071] 14 shows an embodiment of the ring-shaped base piece (400) and cap piece (300) in an unlocked configuration. In this configuration, it can be seen how the retraction element (315) exerts an outward force on the locking hook (404), guiding it away from the circumferential groove of the ostomy implant.

[0072] Figure 15 shows the open / closed and locked configurations of the lid (100). In Figure 15A, the lid (100) is in a closed and locked position. The cap part (300) is locked to the ring-shaped base part (400) when the slider (200) is in the closed configuration. In Figure 15B, the slider (200) has been slid to a retracted position. This can be done without any pivoting. The position in Figure 15B can be referred to as the locked and open configuration. From the position in Figure 15B, the cap part (300) and the ring-shaped base part (400) can be rotated relative to each other to the position in Figure 15C, which shows the lid (100) in an open and unlocked configuration, from which the lid can be removed from the ostomy implant. In the open configuration, the slider (200) protrudes outwardly and can thus be used as a lever or handle to rotate the cap part (300) relative to the ring-shaped base part (400).

[0073] Figure 16 shows an embodiment of a percutaneous ostomy implant (500). The ostomy implant comprises a tubular inner section formed primarily from mesh and a circular radially extending anchoring flange or dermal anchor.
