| 摘要 |
The present invention relates to a surgical anchoring device (1), which is capable of being anchored to the mucous membrane of the inner wall of the intestine (10), and which includes a temporary anchoring element (2), the anchoring of which can be modified in a controlled manner, including a first substantially cylindrical multi-perforated wall having radial elasticity properties such that the outer diameter of said first wall can be changed in a controlled manner, characterised in that at least one portion of the inner surface of said first wall (2a) is lined with a separate inner sealing sleeve, only the longitudinal ends (3a, 3b) of which are attached to said anchoring element (2), so as to define a partial-vacuum chamber (5) between said inner sleeve (3) and said first wall, said temporary anchoring element (2) being coupled to a flexible or semi-rigid tube referred to as the injection/suction tube (6), which extends outside said anchoring element (2), wherein an open end (6a) of said injection/suction tube leads into said partial-vacuum chamber (5), enabling air to be injected into or suctioned from said partial-vacuum chamber. |
