Description

Technical Field

[0001] The present application relates to abdominal drainage, and in particular to a device for closing an abdominal drainage tube cannula channel. Background Art

[0002] During peritoneal drainage, a hole is opened in the abdominal wall to form a channel for the drainage tube to be inserted into the abdominal cavity. The channel needs to be closed after the tube is removed. Unlike the puncture hole, this type of drainage channel generally does not require suturing. The conventional closure method is pressure fixation, which is similar to the hemostasis method for injection needle holes. However, the diameter of the drainage channel is much larger than the diameter of the injection needle hole. The closure is not tight just by applying pressure, resulting in continuous outflow of liquid from the channel, affecting healing. In clinical practice, in order to increase the pressure effect, a downward protruding object is often used to press on the channel. The protrusion has a significant effect in the case of needle hole closure, but the drainage tube channel is long and the diameter is relatively large. The protrusion sometimes easily stretches the channel, which is not conducive to the healing of the channel. Summary of the Invention

[0003] In view of the above problems, the present application aims to propose a peritoneal drainage tube intubation channel sealing device, which can help the tissues around the channel to close the channel, thereby helping the channel to heal quickly.

[0005] and a tube connecting the discharging opening of the second end of the piston rod and the tube connecting the discharging opening of the piston rod. The tube connecting the discharging opening of the second end of the piston rod is connected to the tube connecting line of the piston rod. The tube connecting the discharging opening of the second end of the piston rod is connected to the tube connecting line of the piston rod.

[0028] Below, the abdominal drainage tube intubation channel sealing device of the present application is described in detail with reference to the accompanying drawings.

[0029] The present application proposes a device for sealing a peritoneal drainage tube intubation channel, which includes a plurality of fixing units 10 .

[0030] Each fixing unit 10 includes a base member and a radial adjustment member.

[0031] The base member includes a horizontally arranged bottom plate 11 and a vertically arranged wall plate 12. The wall plate 12 is arranged on the upper side of the bottom plate 11; a guide hole 13 is opened on the wall plate 12. In one embodiment, the wall plate 12 is located at one end of the bottom plate 11 close to the drainage tube insertion channel, such as Figure 3 In another embodiment, the wall plate 12 is located in the middle of the bottom plate 11 (not shown in the figure). In this embodiment, the force rectangle formed by the pulling of the annular lasso mentioned later can be used to press down the tissue.

[0032] The first part 15 of the radial adjustment member can be slidably inserted into the guide hole 13 and the end of the first part 15 of the radial adjustment member is exposed on the first side of the wall plate 12 close to the drainage tube insertion channel, and the end of the second part 14 of the radial adjustment member is exposed on the second side of the wall plate away from the drainage tube insertion channel. The second part 14 of the radial adjustment member is formed into a cylindrical shape and has an external thread formed on its outer circumferential surface. A nut 17 is installed on the second part 14 through the external thread. The outer diameter of the nut 17 is larger than the diameter of the guide hole 13 in at least one direction, so that the nut 17 can stop on the port of the guide hole 13. Thus, the depth of the radial adjustment member inserted into the guide hole is adjusted by adjusting the position of the nut 17 on the second part 14; a notch 16 is formed on the end of the first part of the radial adjustment member.

[0033] The plurality of fixing units 10 are used to surround the drainage tube cannula channel and be fixed on tissues around the drainage tube cannula channel.

[0034] The annular noose 20 is in a tensioned state and is hung on the notch 16 of the end portion of the first portion 15 of each radial adjustment member of the plurality of fixing units 10, as shown in FIG. Figure 1 、 2 As shown in FIG. 1 , the plurality of fixing units fixed around the drainage tube cannula channel are gathered toward the drainage tube cannula channel by the tension of the annular lasso 20, thereby gathering the tissue around the drainage tube cannula channel fixed with the plurality of fixing units toward the drainage tube cannula channel, thereby closing the drainage tube cannula channel.

[0035] In one embodiment, the cross-section of the guide hole 13 is rectangular. Alternatively, the cross-section may be of other shapes, such as elliptical or triangular, to prevent the first portion from rotating within the guide hole 13. This helps ensure that the looped noose is in a plane. Of course, the cross-section may also be circular, but in this case, the looped noose may be out of plane, which is not optimal. However, the purpose of collapsing the fixing unit 10 can still be achieved.

[0036] The plurality of fixing units 10 are evenly arranged in pairs with the drainage tube intubation channel as the center. Generally, they are formed into two pairs, such as Figure 1 、 2 As shown; it can also be formed into 3 or 4 pairs. The fixing units of each pair are opposite to each other, so the closing effect is best.

[0037] In the present application, a pressing unit 30 may be further included.

[0038] The pressing unit 30 includes a film 31 and a pressing head 32 ; the pressing head 32 is formed on the lower side of the film 31 and is located in the middle.

[0039] The pressing head 32 is positioned directly above the drainage tube cannula to apply pressure to the cannula, which is sealed by the multiple fixing units and the noose. The film 31 is adhered to the tissue surrounding the cannula. This pressing action differs from the conventional pressure-assisted hemostasis or sealing technique. The purpose of this pressing action is primarily to ensure that the closed drainage tube cannula does not protrude outward from the body, thus preventing the formation of a deformed healing shape.

[0040] The film 31 is formed with a plurality of extensions 34 by means of spaced notches 33 . The extensions 34 are used to pass through the bottom of the noose and then be adhered to the tissue between the base members of adjacent fixing units.

[0041] The annular lasso 20 can be a common nylon lasso or an elastic lasso made of a rubber band. The annular lasso 20 mainly functions to provide a contraction force for the fixing unit by utilizing its tension.

[0042] During use, the device is first affixed to the patient's body surface around the drainage tube cannula. Next, the patient lasso is placed through the notches in each fixation unit. The position of the nut on the second portion adjusts the depth of the radial adjustment member's insertion into the guide hole, thereby adjusting the tension of the looped lasso. The pressing head is then pressed against the drainage tube cannula, applying the patch to the surrounding tissue. For example, the extension portion can be removed from the underside of the looped lasso and affixed to the space between adjacent bases to increase the adhesive surface area.

[0043] Unless otherwise defined, all technical and / or scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which the invention relates. The materials, methods, and examples mentioned in this application are illustrative only and not restrictive.

[0044] Although the present invention has been described in conjunction with specific embodiments, those skilled in the art may make appropriate substitutions, modifications and changes within the scope of the invention of this application, and such substitutions, modifications and changes shall still fall within the scope of protection of this application.
