Summary
Ultrasound technology and laser-heated forceps are safe and effective for minimally invasive surgery hemostasis. Ultrasound is the most efficacious device, while laser is a promising prototype.
Area of Science:
- Minimally Invasive Surgery
- Surgical Hemostasis
- Energy-Based Devices
Background:
- Laparoscopic surgery necessitates safe hemostasis methods.
- Traditional bleeding control is challenging in laparoscopy.
- Coagulation devices are crucial for minimally invasive procedures.
Purpose of the Study:
- Compare monopolar, bipolar, ultrasound, and laser energy for hemostasis.
- Evaluate coagulation time, efficacy, and tissue damage.
- Assess device performance in a survival splenectomy model.
Main Methods:
- Coagulation of rabbit mesenteric arteries (1-1.5 mm diameter).
- Measurement of coagulation time, hemostasis efficacy, lateral thermal damage, and temperature.
- Survival study: splenectomy in rabbits comparing laser forceps and monopolar electrocautery.
Main Results:
- Bipolar electrocautery was slowest; monopolar caused significant tissue damage and thermal elevation.
- Ultrasound and laser forceps demonstrated equal safety and efficacy.
- Laser forceps cauterized iliac vessels faster with less thermal injury than ultrasound.
Conclusions:
- Ultrasound technology is the safest and most efficacious commercial device for laparoscopic hemostasis.
- Laser-heated forceps show high effectiveness but remain a prototype.
- Both ultrasound and laser offer viable alternatives for minimally invasive bleeding control.
