Abstract

The invention discloses an intra-peritoneal pressure balancing apparatus for use in irrigation of peritoneal cavity. The apparatus comprises a peritoneal trocar sleeve, an irrigating fluid irrigation tube, a negative-pressure suction tube and a control device, wherein the peritoneal trocar sleeve is provided with an inner sleeve and an outer sleeve, and is connected and integrated with a constant-pressure irrigation and suction adjusting valve which is connected with the irrigating fluid irrigation tube, the negative-pressure suction tube and a carbon dioxide intake tube. A rear end of the carbon dioxide intake tube is provided with an automatic air pressure balancing device for balancing the intake pressure of carbon dioxide. An irrigation tube is connected with an external irrigating fluid source. A negative-pressure tube is connected with an external negative-pressure source. The carbon dioxide intake tube is connected with an external carbon dioxide source. A micro computer control board and a leading-out power wire are provided for automatic control. The intra-peritoneal pressure balancing apparatus has the advantages of maintain the balance of the intra-peritoneal pressure during a clinic surgical operation, ensures an operation space in a peritoneal cavity, reduces risks in the operation, improves the quality of the operation and is an intra-peritoneal pressure balancing apparatus for use in operations with a peritoneoscope during various surgeries to balance the intra-peritoneal pressure.

Description

technical field [0001] The invention belongs to a laparoscopic equipment auxiliary appliance of medical equipment, in particular to a peritoneal washing intra-abdominal pressure balancer for balancing the intra-abdominal pressure during the working process of the laparoscopic equipment. Background technique [0002] After the existing laparoscope is cleaned, sucked and exhausted during the operation, the intraperitoneal CO 2 The gas is rapidly reduced, the operating space is rapidly reduced, and the existing CO 2 The gas instrument cannot quickly replenish the CO in the abdominal cavity according to the operation needs 2 Gas is used to maintain the operating space in the abdominal cavity, forcing the operator to wait for 20 to 60 seconds after each operation, and the operation can only be continued after the required air pressure and space are reached in the abdominal cavity. This not only delays the operation time and increases the difficulty of the operation, but also br...
