Abstract

The invention discloses a device for effectively preventing anastomotic leakage. The device includes a long drainage tube and a micropore support structure arranged outside the drainage tube. The device is characterized in that a groove-shaped opening is formed in the front of the drainage tube; a ribbed plate support is arranged inside the groove-shaped opening; and the micropore support structure completely or partially covers the outer side of the groove-shaped opening. The micropore support structure can be a cylindrical sponge structure which arranged on the drainage tube in a sleeving mode, or a sheet-like structure made of an absorbable tissue reinforcement material which warps the outer side of the drainage tube. In addition, a drainage bottle, a negative pressure suction device and a control structure thereon, a pressure sensing piece and the like are arranged to achieve the purpose of intelligently controlling the negative pressure drainage. The micropore support structure isarranged to support the front end of the drainage tube, so that the drainage tube cannot in contact with mucosal tissue, and the goal of enabling drainage to be safer and more effective is finally achieved.

Description

technical field [0001] The invention belongs to the technical field of medical instruments for digestive tract operations, and in particular relates to an anastomotic leakage preventing device after an anastomotic stoma added in the digestive tract is constructed, in particular to a device for effectively preventing anastomotic leakage. Background technique [0002] Most gastric and esophageal anastomosis operations involve reconstruction of the digestive tract. An anastomotic stoma is formed at the site of digestive tract reconstruction. The anastomotic stoma is not stable when it is just formed. At the beginning, it may be due to various factors: such as foreign bodies, such as hematoma, such as diabetes, and gradually form anastomotic leakage. , and there may be gastrointestinal reflux near the anastomosis, saliva and gastrointestinal digestive juice pass through, if the digestive juice around the anastomosis can be fully drawn out in a timely and effective manner, the inc...
