Pyramidal Mirror Laser Scanning for Vaginal Canal Treatment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current laser treatment devices for vaginal canals are inefficient and uncomfortable due to the need for rotating the retractor to achieve 360° treatment, which reduces the effectiveness of the laser beam and causes discomfort for the patient.
Innovation Solution
A device with a pyramidal or truncated pyramidal laser beam reflection mirror that allows the laser beam to be directed orthogonally against the tissue, enabling 360° treatment without rotating the retractor, using a scanning system to move the beam across multiple planar surfaces, maintaining focused energy distribution and avoiding the need for transparent window materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conical mirror is used to reflect the laser beam 360° around the retractor axis, then the entire tissue surface can be treated, but the laser beam is defocussed which reduces treatment effectiveness
Solution Approach 1:
The conical mirror surface is segmented into multiple planar reflecting surfaces arranged in a pyramidal configuration. Each planar surface maintains the laser beam focus while collectively providing 360° coverage through strategic positioning and angular arrangement of the segmented surfaces.
2Adaptability or versatility
If the retractor is rotated to achieve 360° treatment, then all tissue surfaces can be accessed, but the treatment becomes more complex and uncomfortable for the patient
Solution Approach 1:
Instead of rotating the retractor to achieve 360° coverage, the invention inverts the approach by keeping the retractor stationary and using a pyramidal mirror structure that actively directs the laser beam in multiple directions. The mirror configuration allows the beam to sweep across all tissue surfaces without mechanical rotation of the retractor.
Solution Approach 2:
The solution transitions from a one-dimensional rotation approach to a three-dimensional spatial arrangement. The pyramidal mirror structure utilizes angular positioning in multiple dimensions to achieve 360° coverage, allowing the laser beam to access all tissue surfaces through spatial redirection rather than mechanical rotation.
3Loss of energy
If a scanning system moves the laser beam across planar surfaces, then focused energy can be maintained, but the device complexity increases
Solution Approach 1:
The invention uses a pyramidal structure with planar surfaces that collectively create a three-dimensional reflective configuration. This geometric arrangement optimally directs the laser beam across multiple angles while maintaining focus, achieving a balance between structural complexity and functional effectiveness.

Function Achieved in This Case
The solution provides a more efficient, comfortable, and quicker treatment process for the patient by maintaining focused laser energy and eliminating the need for rotating the retractor, allowing for precise control of laser irradiation across the entire tissue surface.
Implementation Method 1
The laser beam reflection mirror is provided with a plurality of flat, i.e. planar reflecting surfaces, formed by the planar side surfaces of the pyramidal laser beam reflection mirror
Implementation Method 2
laser is used to necrotize tumor tissues, to bio-stimulate the growth of particular tissues, for instance cartilaginous tissue for pain treatment and collagen tissue for aesthetic purposes
