Abstract

The invention discloses an integrated surgical operation pneumoperitoneum needle which comprises an outer tube and an inner core, the outer tube comprises a ventilation cavity, one end of the ventilation cavity is used for air inflow, air inflow is conducted in a conventional mode, the other end of the ventilation cavity is connected with two ventilation channels, and the two air inflow channels are oppositely distributed. A sealing plate is arranged in the ventilation channel and divides the ventilation channel into a left cavity and a right cavity, and the right cavity is communicated with the ventilation cavity.

Description

technical field [0001] The invention relates to the field of hepatobiliary surgery. Background technique [0002] Hepatobiliary Surgery mainly studies hepatocellular carcinoma, hepatolithiasis, post-hepatitic cirrhosis and acute liver failure caused by severe hepatitis, which are major diseases that seriously threaten the health of Chinese people. [0003] In hepatobiliary surgery, a Veress needle is needed. There is a spring protection device inside the Veress needle. When puncturing the abdominal wall, the needle core is retracted into the needle sheath when encountering resistance, and the pointed tip of the needle sheath can penetrate the abdominal wall. When the needle sheath Puncture the peritoneum and enter the abdominal cavity to fill the abdominal cavity with carbon dioxide gas, and the resistance disappears. The needle core pops out of the needle sheath under the action of the spring, making the front end of the Veress needle blunt, which can avoid stabbing the abd...
