Special Mention
Lilium
A sustainable, patient-centered alternative to the vaginal speculum

About the project.
The vaginal speculum, one of the most common instruments in gynecological procedures, has seen little change since its invention in 1845, despite its notorious discomfort and controversial history. Designed primarily for healthcare providers’ convenience, it often neglects the patient experience. This discomfort discourages many women from undergoing gynaecological exams, potentially delaying diagnoses and treatment. Although modern updates, such as replacing reusable metal speculums with single-use plastic versions, have been introduced, these changes have raised significant environmental concerns. Lilium is a revolutionary alternative, providing comfort and reducing invasiveness during pelvic exams and procedures like IUD placements while prioritizing environmental sustainability. Lilium offers two insertion options: self-insertion, similar to a tampon applicator, or insertion by healthcare professionals. This empowers patients, transforming them from passive to active participants in their care.
Lilium consists of only two components: an inner part and an exterior part with three blades. Its blade mechanism unfolds like flower petals, promoting psychological comfort with its friendly, non-threatening design. The three-blade system not only enhances cervical visibility by better holding the vaginal walls but also reduces pressure by evenly distributing force, minimizing discomfort and pain. Once inserted and opened, stability is ensured through a simple locking mechanism, allowing the practitioner to proceed with the exam. Additionally, Lilium is designed for minimal environmental impact by being safely reusable. Made from semi-flexible, medical grade TPV, it combines the strength to withstand vaginal wall pressure with the flexibility to gently open its blades and is compatible with autoclave sterilization. Its minimal components streamline the sterilization process, reducing the time needed for disassembly and reassembly without the need for extra tools. The simplified design, free of small holes or screws, further enhances cleaning efficiency and safety.
Jury statement.
“As a jury member, I am impressed by the rethinking of the vaginal speculum, a device that has stayed nearly the same since its invention in 1845. This tool, often linked to fear and discomfort during pelvic exams, has been redesigned to solve these problems. The new flower-inspired design is a great alternative, offering more comfort, less invasiveness, and a focus on sustainability. Lilium is an inspiring step forward that combines care, practicality, and innovation.” – Wolfgang Stegmann
