Mesh patch for use in laparoscopic hernia surgery

摘要

A mesh patch for a laparoscopic hernia surgery, which includes a flexible mesh, an adhesion layer surface, and an anti-adhesion layer surface. The flexible mesh is formed of a thin layer of filament using a biocompatible polymer. The adhesion layer surface is disposed on a front surface of the mesh. The adhesion layer surface is coated with an adhesion inducing material to be fixedly attached to a peritoneum. The anti-adhesion layer surface is disposed on a rear surface of the mesh. The anti-adhesion layer surface is coated with an anti-adhesion material so as not to adhere to intestines in an abdominal cavity. The protection film is detachably attached to the adhesion layer surface and the anti-adhesion layer surface to protect the mesh. Here, the protection film is easily detached by a laparoscopic instrument, and has an adhesive strength such that the mesh is unfolded upon detaching.

1. A mesh patch for use in a laparoscopic hernia surgery, comprising:
a flexible mesh formed of a thin layer of filament using a biocompatible polymer; an adhesion layer surface on a front surface of the mesh, the adhesion layer surface being coated with an adhesion inducing material to be fixedly attached to a peritoneum; an anti-adhesion layer surface on a rear surface of the mesh, the anti-adhesion layer surface being coated with an anti-adhesion material so as not to adhere to intestines in an abdominal cavity; and a protection film detachably attached to the adhesion layer surface and the anti-adhesion layer surface to protect the mesh, wherein the protection film is detachable by a laparoscopic instrument, and has an adhesive strength such that the mesh is unfolded upon detaching, wherein the protection film comprises: a central protection film comprising a central part detachably attached to a central portion of the adhesion layer surface and a connection part extending from one of the central part to one side edge of the mesh; and a peripheral protection film detachably attached to the anti-adhesion layer surface and the adhesion layer surface except the central part, wherein: the central protection film comprises a lower surface attached to the adhesion layer surface and an upper surface folded at the other side of the central part to cover an upper portion of the lower surface; an end of an upper surface of the connection a is attached to the side edge; and a holder portion grippable by the laparoscopic instrument is disposed at the end of the upper surface.
