A new computer-controlled bipolar coagulation system effectively coagulates tissue at 90°C, preventing organ injury. This method achieved complete uterine horn occlusion in rabbits, demonstrating its efficacy for safe and homogenous tissue coagulation.

Area of Science:

Biomedical Engineering
Surgical Technology
Histopathology

Background:

Electrosurgery, particularly electrocoagulation, carries risks of unintended thermal injury to surrounding tissues.
Precise temperature control is crucial for effective and safe tissue coagulation during surgical procedures.

Purpose of the Study:

To develop and evaluate a computer-based, temperature-controlled bipolar coagulation system to minimize complications.
To assess the efficacy of a specific temperature (90°C) for homogenous tissue coagulation and long-term effects.

Main Methods:

A novel computer-based bipolar coagulation system with real-time temperature monitoring was developed.
Rabbit uterine horns underwent electrocoagulation at a controlled temperature of 90°C.
Histological and histochemical analyses were performed 6 weeks post-coagulation.

Main Results:

Electrocoagulation at 90°C resulted in a complete loss of lactate dehydrogenase (LDH) activity in the treated tissue.
Histological examination at 6 weeks revealed complete occlusion of the uterine lumen.

Conclusions:

The developed temperature-controlled bipolar coagulation system is effective for homogenous tissue coagulation.
Low-temperature electrocoagulation (90°C) is sufficient to achieve desired therapeutic outcomes, such as uterine horn occlusion, with reduced risk of complications.
