A disposable Pneumoperitoneum Needle is a surgical tool that is used once and then discarded. It is sterile and is used in laparoscopy to inflate the abdominal cavity with carbon dioxide before a trocar is used during abdominal surgery. The needle is inserted through the skin into the peritoneal cavity to create a pneumoperitoneum before trocars are placed during laparoscopic procedures.
These needles have several features, including a red indicator inside the handle that shows when the blunt stylet is retracted or extended, and an adjustable stopcock to control the flow of gas. The plastic handle has flanges for a comfortable grip, as well as a stopcock and Luer lock for inflating the abdominal cavity. Inside the needle cannula, there is a spring-loaded, blunt stylet that extends beyond the tip. As the needle is pushed through the abdominal wall, the stylet retracts and then automatically advances forward once the peritoneum has been penetrated.
In summary, disposable Pneumoperitoneum Needles are single-use, sterile surgical tools that are used in laparoscopy to inflate the abdominal cavity before a trocar is used during abdominal surgery. They are used to create a pneumoperitoneum before abdominal endoscopy and have features such as an adjustable stopcock to control gas flow and a spring-loaded, blunt stylet mechanism. These needles provide a safe and effective way to create pneumoperitoneum during laparoscopic procedures.
