Design of a Flexible Silicon-based Speculum for Cervical Imaging

Area of Science:

• Biomedical Engineering
• Medical Devices
• Gynecology

Background:

• Commercial stainless-steel speculums can cause patient discomfort during cervical examinations.
• Discomfort may lead to reduced patient compliance in crucial screening procedures.

Purpose of the Study:

• To introduce a flexible silicone probe sheath as a patient-friendly alternative to stainless-steel speculums.
• To assess the structural integrity and optimal design parameters for the silicone probe sheath.

Main Methods:

• A silicone probe sheath, inspired by menstrual cup design, was developed.
• Structural analysis was conducted to determine the optimal thickness balancing deformation and factor of safety (FoS).

Main Results:

• The optimal silicone probe sheath thickness was determined to be 1.60 mm.
• The design minimizes vaginal canal deformation while ensuring adequate safety.

Conclusions:

• The silicone probe sheath offers a comfortable and potentially more accessible alternative to traditional speculums.
• This innovation may enhance patient compliance and participation in cervical cancer screening through self-insertion.
