ABDOMINAL MONITOR Russian patent published in 2015 - IPC A61B17/34 

FIELD: medicine.

SUBSTANCE: invention refers to disposable surgical instruments and can be used as a trocar. A disposable device consists of a kit (a port, a mandrin, a T-connector, a drain tube and sealing covers), which is assembled in specific combinations to perform various manipulations for monitoring a pathological process in the abdominal cavity through the presented device without a repeated laparocentesis. The kit parts are hermetically coupled. An inner surface of a port nozzle has fittings to shape the inner surface of the nozzle wavily to reduce friction. The port is made of an elastic polymer material, while the mandrin is made of a polymer material. The T-connector is made of a rigid polymer and has a branch pipe to form a pneumoperitoneum. A laparoscope or an elastic drain tube can be inserted through the T-connector and port to monitor the pathological process in the abdominal cavity and to perform low-invasive interventions without the repeated laparocentesis.

EFFECT: dynamic monitoring of the abdominal cavity, excluding the negative effect on the body tissues and combining the principles of a searching catheter, laparoscopy, dynamic laparoscopy and passive drainage.
