Description

Artificial ostomy device

Technical Field

The invention relates to an auxiliary artificial substitute organ applied to a human body, in particular to an artificial ostomy device.

Background

The artificial stoma is used for cutting off the intestinal tract with pathological changes when the intestinal tract of a patient suffers from pathological changes, and forming an opening for connecting the cut-off intestinal tract and draining the intestinal tract at other parts of the body of the patient. The purpose of applying artificial stomas is usually to replace the function of the downstream diseased or even cut-off intestine or to allow a temporary replacement when the downstream intestinal rest is restored.

Referring to fig. 1, there is shown a conventional artificial ostomy device 2 adapted to be installed in an intestinal tract 11, which is severed to form a port 110, and an opening 120 formed in a human body 12. The intestinal tract 11 extends from the inside to the outside through the opening 120, and the port 110 faces to the outside. The ostomy device 2 comprises a supporting part 21 adapted to extend from the port 110 into the intestine 11, and a positioning part 22 for connecting the outside of the supporting part 21.

The supporting member 21 is hollow and includes an inner ring 211 adapted to support the inner side of the intestinal tract 11, an extending tube 212 connected to the inner ring 211 and extending in an axial direction while contracting radially inward, and an outer ring 213 connected to the extending tube 212 and defining an opening 219. The positioning element 22 is adapted to be attached to the outside of the human body 12, and includes a circular portion 221 defining a through hole 220, and a plate portion 222 extending outward from the circular portion 221 and adapted to be attached to the human body 12. The radial width of the inner ring 211 is greater than the radial width of the outer ring 213, and when the supporting member 21 is extended into the intestinal tract 11, the inner ring 211 radially supports the intestinal tract 11 outward to form an expanded portion 111, and the expanded portion 111 is extended outward by cooperating with the extension tube 212, so that the expanded portion 111 abuts against the inner side of the human body 12, thereby positioning the intestinal tract 11. The outer ring 213 surrounds the port 110 of the intestinal tract 11, so that the opening 219 is open to the outside in communication with the intestinal tract 11. The outer ring 213 is pressed against the outer side of the human body 12, and the expansion portion 111 is pressed against the inner ring 211 inside the human body 12, so that the intestinal tract 11 can be fixed in the opening 120. Then, the circular portion 221 of the positioning element 22 covers the outer ring 213 of the supporting element 21, and the plate portion 222 is attached around the opening 120 in a matching manner, so that the supporting element 21 can be positioned by the positioning element 22. At this time, the opening 219 is opened outward, and the excreta transported from the intestinal tract 11 can be discharged outward through the opening 219.

However, in addition to the way of forming the outlet communicating the inside of the intestinal tract 11 by directly blocking the intestinal tract 11 to form the port 110, if the artificial stoma is not permanently disposed, in order to prevent necrosis of the downstream of the intestinal tract 11 due to direct blocking, it is also possible to form the one-side opening 119 on the side surface of the intestinal tract 11 as shown in fig. 2, so as to maintain the connection between the upstream and downstream of the intestinal tract 11, and to secure the normal physiological circulation of the intestinal tract 11 to prevent necrosis. When the intestinal tract 11 is rested at the position opposite to the downstream of the side opening 119, the intestinal tract 11 can be normally operated again. However, in the case of the method shown in fig. 2, the artificial ostomy device 2 shown in fig. 1 cannot be installed in a matching manner, and if the intestinal tract 11 is directly sutured to the human body 12 such that the side opening 119 is communicated with the opening 120, although the artificial stoma can still be formed, the excreta transported from the upstream to the downstream of the intestinal tract 11 may continue to be transported downwards, which may affect the recovery of the intestinal tract 11 located at the downstream of the side opening 119. Therefore, it is necessary to provide a matching ostomy device for the application method as shown in fig. 2 to ensure the achievement of the purpose of artificial ostomy application.
