Development of a carbon dioxide laser cystoscope

Area of Science:

• Urology
• Surgical Technology
• Biomedical Engineering

Background:

• The carbon dioxide laser offers precise tissue interaction for surgical applications.
• Evaluating laser parameters is crucial for optimizing surgical outcomes and safety.

Purpose of the Study:

• To characterize carbon dioxide laser-induced lesions on canine bladders.
• To assess the relationship between laser energy and lesion depth.
• To investigate healing, thermal effects, and hemostasis of laser lesions.

Main Methods:

• Utilized a 50-watt continuous carbon dioxide laser coupled with a surgical microscope.
• Studied laser-induced lesions on exteriorized canine bladders.
• Developed and tested a prototype carbon dioxide laser cystoscope for endoscopic application.

Main Results:

• Established the relationship between laser energy and lesion depth.
• Observed healing patterns of laser-created lesions.
• Evaluated vertical temperature transmission and hemostatic capabilities of the laser.

Conclusions:

• Carbon dioxide laser parameters can be controlled to create predictable surgical lesions in the bladder.
• The developed laser cystoscope demonstrates feasibility for endoscopic bladder surgery.
• Results support the potential of carbon dioxide laser technology in urological procedures.
