Abdominal puncture rod and puncture outfit with electric knife and extraction balloon

Abstract

The invention discloses an abdominal puncture rod and a puncture outfit with electric knife and extraction balloon. The puncture rod comprises a puncture head; the puncture head is connected with thepuncture rod base through a cylindrical connecting rod; the external wall of the cylindrical connecting rod is provided with an annular groove, a first balloon and a second balloon are arranged in theannular groove, and the second balloon is positioned on the outer side of the first balloon; a first electric knife bit used for electrocoagulation is arranged on the puncture head; a second electricknife bit used for electrocoagulation is arranged on the second balloon; the cylindrical connecting rod is internally provided with a first lumen communicated with the first balloon and a second lumen communicated with the second balloon at one end; the other ends of the first lumen and the second lumen respectively extend to the puncture rod base and are respectively communicated with a first water injection joint and a second water injection joint on the puncture rod base. By filling the first balloon or filling the first balloon and the second balloon at the same time, the abdominal incision can be gradually expanded; the second electric knife bit closes an electric cutting current, and the expansion effect of the first balloon and the second balloon can be improved.

Description

technical field [0001] The invention relates to a peritoneal puncture device, in particular to a peritoneal puncture rod and a puncture device with an electric knife and an expansion balloon. Background technique [0002] Gallbladder stones and cholecystitis are frequently-occurring and common diseases in my country, and cholecystectomy is one of the common surgical methods for the treatment of this disease. Traditional cholecystectomy is an open operation, which has the disadvantages of large trauma and slow recovery. With the development of laparoscopic technology, laparoscopic cholecystectomy has become the gold standard in the treatment of gallbladder stones, with the advantages of less trauma and faster recovery. [0003] At present, the abdominal puncture device is a kind of surgical instrument for entering the abdominal cavity for other surgical instruments in laparoscopic cholecystectomy by puncturing the abdominal wall. In the prior art, the laparoscopic puncture ...

Problems solved by technology

When the gallbladder is edematous or there are many stones in the gallbladder cavity, it is difficult to take out the gallbladder and stones completely. At this time, scissors are often used to cut the gallbladder tissue into pieces, and the stones in the gallbladder cavity can be removed one by one before the specimen bag can be taken out, which greatly prolongs the operation time. The operation time is long, and the specimen bag is prone to damage during the removal of the gallbladder and stones, causing stones and gallbladder tissue to enter the abdominal cavity, and even the abdominal cavity and abdominal wall of the tumor to grow.
