Medical Knowledge Related to Disposable Veress Needle
The Working Principle of Disposable Veress Needle
A disposable veress needle is a special disposable laparoscopic puncture needle with a safety device, designed based on Veress's principle. The front end of the needle core is blunt and round, with side holes for injecting water, gas, and suction. A spring is installed at the tail. When encountering resistance while puncturing the abdominal wall, the needle core retracts into the sharp needle sleeve. Upon entering the abdominal cavity and the resistance disappearing, the spring ejects the needle core to avoid accidental injury to abdominal organs by the needle sleeve.
Steps for Using Disposable Veress Needle
Confirm whether the sterile packaging bag is damaged and whether the sterilization date has expired. If there are no issues, take out the disposable veress needle.
Ensure that the rotary knob of the disposable veress needle is in the closed state, and use the gas tube to connect it to the hospital's pneumoperitoneum machine.
Insert the pneumoperitoneum needle through the navel and confirm entry into the abdomen.
Open the rotary knob to inject gas, and after inflating to the specified pressure, remove it.
Advantages of Disposable Veress Needle
Safety
As a single-use medical device, the disposable veress needle can avoid the risk of cross-infection that may come with repeated use. Ensuring patient safety during surgery is crucial; thus, using a disposable veress needle significantly reduces infection risk.
Convenience
The disposable insufflation veress needle does not require complex processes such as cleaning and sterilization and can be discarded after use, greatly simplifying the preparation and handling processes before and after surgery. This helps to shorten surgery time and improve surgical efficiency.
Hygiene
The disposable veress needle undergoes strict sterile processing, and its packaging must be checked for integrity before each use to ensure sterility. This helps ensure hygienic conditions during the surgery, reducing infection risk.
Economy
Although the unit price of a disposable veress needle may be slightly higher, it requires no additional costs for cleaning, sterilization, and maintenance due to its single-use nature. In the long run, using a disposable veress needle can save hospitals costs related to device handling and maintenance.
Reduction of Complications
The design of the disposable veress needle is usually simpler and easier to operate, reducing the risk of complications due to improper operation or equipment failure. Furthermore, its sharp tip and user-friendly characteristics also help doctors perform surgical operations more accurately.
Due to its safety, convenience, hygiene, economy, and alignment with modern medical trends, the disposable veress needle is being increasingly adopted by medical institutions and doctors.
