Abstract: A medical device is disclosed, which capable of reducing risk factors of an anastomotic leakage after a surgical operation is performed. The adhesion promoting device includes an adhesion promotion sheet provided with an adhesion promotion portion that promotes adhesion of biological tissues, and a holding portion that allows the adhesion promotion sheet to be hooked and held on a biological organ to be joined.

Abstract: A medical device is disclosed capable of reducing risk factors of an anastomotic leakage after a surgical operation is performed. The medical device includes an adhesion promotion sheet configured to include an adhesion promotion portion promoting adhesion of biological tissues and a frame portion provided outside the adhesion promotion portion in a plane direction and a pulling unit connected to the adhesion promotion sheet and configured to deform a second region so as to cover at least a portion of an outer peripheral surface of a biological organ to be joined with a pulling operation.
