Inflatable Vaginal Speculum with Adjustable Diameter and Depth
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vaginal speculums fail to provide an unobstructed view of the vaginal canal, cervix, and vaginal fornices due to insufficient dilation and collapse of lateral walls, especially in patients with altered anatomy or higher Body Mass Indexes. Additionally, existing speculums lack effective illumination and irrigation features.
Innovation Solution
The development of an inflatable vaginal speculum with a coaxial quasi-cylindrical annular frame arrangement, allowing for adjustable diameter and depth of insertion, integrated illumination, and irrigation capabilities to maintain clear visualization and comfort during examinations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional fixed-length speculum blades are used, then the structure is simple and easy to manufacture, but the speculum cannot adapt to different anatomical variations and cannot provide adequate access to the cervix in patients with altered anatomy or higher BMI
Solution Approach 1:
The speculum incorporates telescopic blades with multiple segments that can extend and retract along guide beams, allowing the length to be dynamically adjusted based on patient anatomy and procedural needs. This dynamic structure enables adaptation to varying vaginal canal lengths and cervical positions while maintaining a compact form when not in use.
Solution Approach 2:
The speculum blades are divided into multiple telescopic segments that can extend independently along the longitudinal axis. Each segment can be adjusted to achieve the required length, providing versatility for different anatomical configurations while keeping the base structure relatively simple.
2Ease of operation
If the speculum blades are expanded to dilate the vaginal canal, then access to the cervix is improved, but the lateral walls may collapse in patients with lax tissue, obstructing the view
Solution Approach 1:
The speculum features an inflatable annular balloon that can be inflated with fluid to provide dynamic radial support to the vaginal canal walls. This inflatable structure adapts to the patient's anatomy and maintains lateral wall expansion stability throughout the procedure, preventing collapse even in patients with lax tissue.
Solution Approach 2:
An inflatable balloon element is integrated into the speculum structure, utilizing hydraulic inflation with fluid to generate uniform radial pressure. This pneumatic-hydraulic mechanism provides reliable and adjustable support to maintain the patency of the vaginal canal and prevent lateral wall collapse during examination or surgical procedures.
3Length of moving object
If the speculum is made longer to reach the cervix in patients with higher BMI, then access is improved, but the rigidity may increase causing patient discomfort
Solution Approach 1:
The speculum incorporates telescopic blades that can extend to the required length only when needed, rather than being permanently long. When retracted, the speculum maintains a shorter, more flexible profile that is comfortable for insertion and does not cause patient discomfort.
Solution Approach 2:
The speculum utilizes flexible telescopic segments connected by joints that allow bending and adaptation to the natural curvature of the vaginal canal. This flexibility reduces rigidity-related discomfort during insertion and positioning, even when the speculum is extended to greater lengths.
4Illumination intensity
If conventional speculums are used without illumination, then the structure is simple, but adequate visualization of the vaginal canal and cervix cannot be achieved
Solution Approach 1:
The illumination system is integrated directly into the speculum structure, with light sources positioned at strategic locations along the blades and cervix-facing surfaces. This merging of illumination and examination functions into a single device provides adequate visualization while avoiding the need for separate lighting equipment.
Solution Approach 2:
The speculum is designed as a multi-functional device that combines examination, illumination, irrigation, and evacuation capabilities in one instrument. This universal design eliminates the need for multiple separate devices while providing comprehensive functionality for gynecological procedures.
5Ease of operation
If conventional speculums are used without irrigation capability, then the structure is simple, but secretions cannot be effectively cleared from the examination area
Solution Approach 1:
The speculum integrates irrigation channels and spray nozzles directly into the blade structure, enabling fluid delivery to the examination area through the same device used for visualization. This multi-functional integration allows effective clearance of secretions without requiring separate irrigation equipment.
Solution Approach 2:
The irrigation function is merged with the speculum structure, with fluid delivery channels incorporated into the blades and connection ports integrated into the handle. This combining of functions into a single device simplifies the overall system while providing effective secretion clearance capability.
