This study simulates uterine distension and fluid flow during hysteroscopy. These simulations aid gynecologists in visualizing the uterine cavity for improved surgical procedures.

Area of Science:

Medical simulation
Computational fluid dynamics
Biomechanical modeling

Background:

Hysteroscopy requires uterine distension (hydrometra) for visualization.
Intrauterine pressure and fluid dynamics are critical for surgical clarity.
Accurate simulation of hydrometra is essential for surgical planning and training.

Purpose of the Study:

To present simulation methods for uterine muscle distension and fluid flow during hysteroscopy.
To evaluate the real-time capabilities and fidelity of the proposed simulation algorithms.

Main Methods:

Uterine muscle deformation computed offline using finite element analysis.
Fluid flow approximated in real-time by solving simplified Navier-Stokes equations.
Integration of biomechanical and fluid dynamics simulations for hydrometra.

Main Results:

Demonstrated offline computation for organ deformation and real-time approximation for fluid flow.
Achieved a balance between computational speed and simulation accuracy.
Validated the proposed methods for simulating hysteroscopy conditions.

Conclusions:

The presented simulation approach enhances understanding of hydrometra dynamics.
These methods offer potential for improved surgical planning and training in hysteroscopy.
Real-time simulation capabilities are crucial for interactive surgical guidance.
