Embodiment

[0032] A temporary abdominal closure device, see Figure 1-2 , including anti-infection biopermeable membrane 1, large mesh polypropylene monofilament mesh 2, polydioxanone 3, folds 4, abdominal wall zipper 5, blocking material 6, drainage tube 8, The permeable film 7, the plugging material 6, the drainage tube 8, and the permeable film 7 form a negative pressure drainage system.

[0033] In this embodiment, the biopermeable film can use acellular matrix biomaterials based on collagen scaffold structure or other biomimetic collagen scaffold materials or even collagen gel materials, acellular matrix biomaterials such as porcine small intestinal submucosa, artificial acellular dermis, etc. , the material source can be human or mammalian, and the source tissue can be small intestinal submucosa, dermis, basement membrane, peritoneum, amniotic membrane, pericardium, etc.; polypropylene mesh (PPM) is an ultra-thin and lightweight mesh with a mesh density of 32g / m2 , single-strand f...

Abstract

The invention discloses a temporary abdomen closing device, which can solve the problems of poor infection resistance, abdominal cavity visceral organ adhesion, repeated abdomen opening and closing and abdominal effusion drainage, and comprises: an anti-infective biopermeable film, wherein the anti-infective biopermeable film directly contacts abdominal organs, is not easy to adhere, has a certainantimicrobial activity, and is quick in tissue cell growth; a mesh sheet, wherein the mesh sheet maintains a certain low tension of an incision, prevents fascia from shrinking, and guides tissue regeneration; a binder; wrinkles, wherein the wrinkles can be released to reduce incision tension when the pressure in the abdominal cavity rises; an abdominal wall zipper, wherein the abdominal cavity can be fully exposed through the double-opening design so as to conveniently operate in the abdominal cavity; and a negative pressure drainage system formed by a blocking material, a drainage tube and apermeable pasting film, wherein the negative pressure drainage system drains percolate and necrotic tissue in the abdominal cavity in time so as to accelerate wound healing.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a temporary abdominal closure device. Background technique [0002] The current concept of treatment for severe trauma, extensive burns, and critically ill patients advocates "damage control surgery" (DCS). Taking the abdomen as an example, the first laparotomy for severe trauma is only performed with hemostasis, stoma and drainage, and shortens as much as possible. During the operation time, there is no organ repair and reconstruction. Routine abdominal closure is unnecessary and time-consuming due to the need for reoperation under DCS conditions. However, in order to prevent loss of body fluid and body heat, temporary abdominal closure (Temporary abdominal closure, TAC) should be used. Such patients are often accompanied by "abdominal compartment syndrome" (Abdominal compartment syndrome, ACS). The preferred treatment is the exact and effective decompression of the abdominal ca...
