    Abstract: A device for use in performing examinations and surgical interventions within the abdominal cavity of a patient comprises a cowling having a marginal area which is applicable to the abdominal integument of the patient and which is provided with an upper temporarily closable opening in communication with an annular projection which is directed into the inside of the cowling and which has a free end which is applicable in hermetic contact with the abdominal integument, whereby a negative pressure generated within the cowling raises the abdominal integument. Optional instruments may thereupon be inserted through the opening and via the abdominal integument into the abdominal cavity without damaging any internal organs and vessels which were initially in contact with the inner side of the abdominal integument.
