Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tissue resection methods with energy sources often lack accuracy and are more invasive than desired, due to imprecise positioning of energy sources and challenges with tissue variability and movement.
Innovation Solution
The system employs probes with energy sources that can be offset from the elongate probe axis, allowing for controlled rotation and translation of the energy source, and can receive a second treatment probe for improved positional accuracy and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If energy source is positioned on elongate probe axis, then probe structure is simple, but tissue resection accuracy is reduced
Solution Approach 1:
The energy source is positioned at an offset distance from the elongate probe axis, transitioning from a one-dimensional axial arrangement to a two-dimensional offset configuration. This allows the energy source to be positioned at different radial distances from the axis, enabling improved tissue resection accuracy while maintaining a relatively simple probe structure.
Solution Approach 2:
The system enables dynamic adjustment of the energy source position through controlled rotation and translation mechanisms. The energy source can be rotated about the elongate probe axis and translated along the axis, allowing real-time adaptation to varying tissue conditions and surgical requirements.
2Adaptability or versatility
If single energy source is used, then device complexity is low, but treatment versatility is limited
Solution Approach 1:
The system combines multiple energy sources (first treatment probe with first energy source and second treatment probe with second energy source) within a single integrated probe structure. The probes are configured to be received within each other, creating a nested arrangement that enables multiple energy delivery capabilities while maintaining a compact form factor.
Solution Approach 2:
The probe is designed with universal receptacle structures that can accommodate different treatment probes with various energy sources. This multi-functional design allows the same base probe to support different treatment modalities, enhancing versatility without requiring entirely separate device systems.
3Measurement precision
If energy source is fixed on probe axis, then positioning is simple, but positional accuracy is reduced
Solution Approach 1:
The system incorporates control mechanisms that enable precise control of the energy source position through rotation and translation. The control system can monitor and adjust the energy source location in real-time, providing feedback control that maintains high positional accuracy while simplifying the operator's control through automated or semi-automated positioning assistance.
Data Source
AI summary
An energy source is offset from an elongate probe axis with an extension. The amount of offset of the energy source can be controlled by varying an amount of offset of the extension. The energy source rotated and translated at the offset distance to resect tissue. In some embodiments, the probe is configured to receive a second treatment probe comprising a second energy source, in which the second energy source is rotated and translated relative to the first treatment probe, which can improve positional accuracy and stability. The energy source and the extension can be coupled to a linkage to offset the energy source, and to translate and rotate the energy source with varying amounts of offset. The linkage can be coupled to a processor and one or more of the energy source moved in accordance with a treatment profile.
