Solution Overview
Problem
Current methods for removing tissue lesions, particularly in the lungs, are inefficient and invasive, often requiring multiple procedures and resulting in significant tissue damage and lengthy recovery times due to the limitations of fine needle biopsies and traditional surgical techniques.
Innovation Solution
A tissue coring system utilizing a helical coil electrode and tracking apparatus for precise three-dimensional positioning, allowing for the removal of a core tissue sample with minimal healthy tissue removal and the option for localized treatment, followed by sealing the cavity using energy-based methods or fill materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If fine needle biopsy is used to remove tissue lesions, then the procedure can be performed with minimal invasiveness, but the diagnosis accuracy is insufficient and multiple procedures are required
Solution Approach 1:
The device segments the tissue removal process into two distinct stages: first, a fine needle performs a minimally invasive biopsy to obtain tissue samples for diagnosis; second, a coring device removes the entire lesion as a core sample. This segmentation allows each stage to optimize for its specific function, resolving the contradiction between minimality of invasiveness and diagnosis accuracy.
Solution Approach 2:
The fine needle biopsy is performed as a preliminary action before the coring procedure. The biopsy establishes diagnosis accuracy while maintaining minimal invasiveness, and then the coring device uses this information to guide the removal of the entire lesion. This preliminary action resolves the contradiction by sequentially addressing diagnosis accuracy and then complete lesion removal.
2Reliability
If traditional surgical techniques are used to remove tissue lesions, then complete lesion removal is achieved, but significant tissue damage occurs and recovery time is lengthy
Solution Approach 1:
The coring device is designed to remove only the lesion and immediate surrounding tissue as a precise core sample, rather than performing extensive surgical resection. This local quality approach ensures complete lesion removal while minimizing damage to surrounding healthy tissue, thereby reducing recovery time while maintaining reliability.
Solution Approach 2:
The invention replaces traditional mechanical surgical techniques with a coring mechanism that extracts the lesion as a core sample. This substitution of the mechanical removal approach allows for complete lesion removal with significantly reduced tissue damage and shorter recovery times compared to traditional surgery.
3Reliability
If multiple procedures are performed to diagnose and treat tissue lesions, then comprehensive treatment is achieved, but the overall time required increases
Solution Approach 1:
The device merges the biopsy and lesion removal functions into a single integrated procedure. The fine needle first obtains tissue samples for diagnosis, then the coring device removes the entire lesion in the same operational sequence. This merging eliminates the need for multiple separate procedures, achieving comprehensive treatment while reducing overall time required.
Solution Approach 2:
The device system is designed with multi-functionality, where the fine needle and coring device work together in a single procedure to both diagnose and treat the tissue lesion. This universal approach allows comprehensive treatment (diagnosis + lesion removal) to be achieved in one procedure rather than requiring multiple separate interventions, thereby reducing total time loss.

AI summary
A method for removing tissues may comprise disposing a tissue resection device at a target tissue site, causing the tissue resection device to resect a core of tissue from the target tissue site, removing the core of tissue from the body, wherein the removing the core of tissue from the body creates a core cavity at the target tissue site. A tracking apparatus may be configured to determine a position of a portion of the tissue resection device in three dimensional space.
