What is bipolar resectoscope?

The bipolar electrosurgical resectoscope is an advanced minimally invasive surgical device that generates localized plasma in tissues through high-frequency currents for cutting and coagulation. It utilizes saline as the conductive medium, eliminating the risk of current passing through the entire body as seen in traditional monopolar electrosurgery, thereby offering higher safety.

Core strengths
High safety: The current circuit is localized to the electrode area, eliminating the need for a negative electrode plate, significantly reducing the risks of burns and water intoxication.
Minimal tissue damage: Low-temperature plasma technology (approximately 40-70°C) results in shallow thermal penetration, minimal carbonization of the cut surface, and extremely low damage to surrounding tissues (e.g., nerves)
First-class A.
Excellent hemostasis: Continuous coagulation during cutting reduces intraoperative bleeding, ensures clear visualization, and minimizes irrigation time and postoperative complications.
Rapid recovery: Few postoperative complications, short hospital stays, and quick patient rehabilitation.
Wide Applicability: Suitable for various surgeries such as benign prostatic hyperplasia, bladder tumors, endometrial polyps, and intrauterine adhesions.
Applicable scenarios
Urology: Treats benign prostatic hyperplasia and bladder tumors.
Gynecology: Treatment of endometrial lesions, intrauterine adhesions, submucosal myomas, and more.
Precautions
It must be performed by a qualified physician, and the patient's condition should be evaluated before the procedure.
The price may be higher than that of traditional unipolar electrosurgical devices.
In summary, the bipolar electroscalpel is a safe, efficient, and minimally invasive surgical tool that can significantly improve patient outcomes.

Operation skills of bipolar resectoscope

1, Basic operation points
Device connection and setup: After connecting the bipolar cable, the device usually automatically recognizes and calls up the operation menu (such as ARC360 electric cutting mirror). When setting the power, the cutting mode is generally around 200W, and the solidification mode is around 120W.
Irrigation fluid selection: Physiological saline (0.9% NaCl) must be used as the irrigation fluid, which is the safety advantage of bipolar technology ^ [Historical answer] ^.
Use of foot switch: The foot switch is usually divided into two gears, with the front step for cutting and the rear step for solidification. When operating, keep your foot steady to avoid accidental contact.
2, Core operational skills
Balance between cutting and solidification: Adopting the strategy of "cutting while solidifying", using solidification function appropriately during cutting to reduce bleeding and maintain clear vision ^ [Historical answer] ^.
Avoid thermal damage:
Control clamping time: The clamping time for each tissue should be less than 3 seconds to prevent tissue carbonization.
Adopting the "point touch" method: In fine operations such as hysteroscopy, avoid prolonged continuous scanning and heating, and adopt a point like, short cutting method.
Seal first, then cut ": For tissue with a pedicle, first use solidification function to seal the base before cutting, which can effectively reduce thermal diffusion damage.
Equipment protection: Pay attention to protecting the optical tube and lens during operation to avoid collisions. After use, it is necessary to disassemble according to the specifications. First, turn off the water source, and then disassemble each component in sequence.
3, Advanced operational skills
Push cutting technique: In surgeries such as transurethral resection of the prostate, push cutting (electric cutting mirror forward cutting) is safer and more efficient than traditional "retraction cutting", especially suitable for cutting the bladder neck and other parts.
Segmented processing of large tissues: For larger tissues (such as the prostate gland), segmented resection or "knife dragging resection" techniques can be used. The starting point is fixed first, and then the cutting is gradually stepped back to improve surgical efficiency.
Vascular treatment technique: When encountering larger blood vessels, the distal end should be clamped first, and then the coagulation should be released in sections to avoid thermal damage to the proximal end.
4, Safety and Precautions
Strictly follow the operating procedures: avoid hot plugging and confirm the device status before connection.
Prevention of complications: Pay attention to irrigation fluid pressure during surgery to prevent TUR syndrome. Close observation of the patient's vital signs and urine color after surgery ^ [Historical answer] ^.
Teamwork: Operating room nurses need to be proficient in the key points of instrument transfer and maintenance to ensure smooth surgery.
