Understanding Disposable Bipolar Laparoscopic Forceps
Disposable bipolar laparoscopic forceps play a crucial role in modern laparoscopic surgery. Not only do they provide precise electrocoagulation function, but they also greatly enhance the safety and efficiency of the surgery. This article will introduce the basic principles, operating steps, and usage techniques of disposable bipolar laparoscopic forceps.
The Working Principle of Disposable Bipolar Laparoscopic Forceps
The disposable bipolar laparoscopic forceps are designed with a unique current transmission method, providing significant advantages for laparoscopic surgery. Since the advent of bipolar electrocoagulation in 1940, compared to traditional monopolar electrocoagulation, it eliminates the ineffective electrodes in contact with the patient, reducing the required current. The current only passes through the tissue between the two tips of the forceps, reducing the electrical demand to a quarter to a third of monopolar electrocoagulation.
During the application of the disposable bipolar laparoscopic forceps, the current passes between the bipolar poles, causing deep coagulation to spread in a radial pattern, thus achieving efficient hemostasis. Compared to monopolar electrocoagulation, disposable bipolar laparoscopic forceps are more precise in hemostasis with significantly reduced collateral damage to the surrounding tissues. Due to its circuit design, the disposable bipolar laparoscopic forceps do not require a grounding pad, further enhancing the safety and precision of the surgery.
Operating Steps and Tips for Bipolar Laparoscopic Forceps
Operating Steps
When using disposable bipolar laparoscopic forceps, follow these steps:
Power On: First, connect the footswitch, place it under the surgeon's foot, and power on for self-check. Set the output power as per the surgical requirements.
Connect Forceps: Connect the cable plug of the disposable bipolar laparoscopic forceps to the power supply.
Clamp Tissue: Use the disposable bipolar laparoscopic forceps to clamp the target tissue or bleeding point, press the footswitch to perform electrocoagulation hemostasis, and release the footswitch after the operation is completed.
End Operation: After use, first turn off the main switch and then unplug the power plug.
Usage Tips
Mastering the following tips can improve the effectiveness of the disposable bipolar laparoscopic forceps:
Choose the proper forceps and output power: Select the appropriate disposable bipolar laparoscopic forceps and 30-50W output power based on the type of surgery and the nature of the tissue.
Keep the tissue tension-free: Maintain a clean operating field during the procedure to avoid the impact of high temperatures on nearby vital tissues. Each electrocoagulation time should be controlled within 3 seconds, repeating multiple times to achieve the best results.
Remove eschar: Promptly remove the eschar on the disposable bipolar laparoscopic forceps using a wet gauze or a special non-damaging cloth to prevent the eschar from affecting electrocoagulation effectiveness.
Avoid short circuit: Ensure the two ends of the disposable bipolar laparoscopic forceps maintain a certain distance to prevent current short-circuiting and causing failure.
Cautious use of heat: Reduce the electrocoagulation output and time when coagulating near important tissues to avoid excessive damage to the tissue.
As a key tool in modern laparoscopic surgery, disposable bipolar laparoscopic forceps have become indispensable in laparoscopic surgeries owing to their efficient electrocoagulation function and precise operational advantages. Understanding their working principles, operating steps, and usage techniques can significantly improve the safety and outcomes of surgeries, providing patients with higher quality medical services.
