Novel film-coated plugging disc
A blocking disk and film-covering technology, which is applied in the field of medical devices, can solve the problems that the blocking disk and flow-blocking film cannot be completely covered, the thickness of the film cannot be too thick, and the sealing is not complete, so as to achieve controllability and Fully repeatable recyclability, avoiding direct contact, and reducing frictional resistance

Example Embodiment
[0085] Example 1
[0086] like Figure 1-3 As shown, this embodiment provides a novel film-coated plugging disc, which includes a plurality of support rods with elasticity and / or shape memory, a first blocking film and a first deformation compensation structure 4; wherein, the plurality of support rods The first support development surface 1, the lumbar support development surface 3 and the second support development surface 2 extend from the first central portion 6 in sequence, and converge on the second central portion 7 to form a cage-like structure; the first flow blocking film includes a bag Covering film 5, the covering film 5 is covered on the outer surface of the first central portion 6, the inner and outer surfaces of the first supporting unfolding surface 1 and the outer surface of the waist support unfolding surface 3, and the distal edge of the covering film 5 is connected to the second. The supporting and unfolding surfaces 2 are connected by a first deformation ...
Example Embodiment
[0092] Example 2
[0093] like Figure 10-12 Compared with Example 1, the first difference between Example 2 and Example 1 is that the first flow blocking film further includes a reinforcing blocking body 9, which is arranged on the second supporting development surface of the blocking disk. 2, the edge of the reinforcing blocking body 9 is connected with the edge of the covering film 5 and the waist support unfolding surface 3 through the first deformation compensation structure 4, so that in the natural state, the covering film 5 and the reinforcing sealing body 9 are formed. In a closed cage shape adapted to the shape of the plugging disc, the reinforcing plugging body 9 is made of a flexible film, and the flexible film has a microporous structure 51 , and the microporous structure 51 is convenient for liquid to enter and exit. In addition, the microporous structure 51 is more conducive to tissue growth, so the reinforcing blocking body 9 provided in the blocking disk is a...
Example Embodiment
[0100] Example 3
[0101] refer to Figure 14 , 15 The first difference between Example 3 and Example 1 is that the covering film 5 not only covers the lumbar support development surface 3 but also covers the second support development surface 2, and the covering film at the second support development surface 2 5 is provided with a microporous structure 51, so that the liquid can enter and exit, which is convenient for preoperative emptying.
[0102] The second difference is that: Figure 15 Among them, the first deformation compensation structure 4 is located at the edge of the coating film 5, and the first deformation compensation structure 4 is a series line on a plurality of independent support rods surrounding the second support development surface 2, and the series line passes through or Winding a plurality of independent support rods and covering films 5 on the second support unwinding surface 2, so that the series lines are connected end to end. The advantage of th...
