Integrated Laser Morcellator for BPH Tissue Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical techniques for treating Benign Prostatic Hyperplasia (BPH) require multiple steps and tools, leading to prolonged procedure times and increased risk of anatomical damage due to obstructed visibility during prostate tissue removal.
Innovation Solution
A multi-use surgical tool integrating a laser fiber and a morcellator allows for simultaneous enucleation and morcellation of prostate tissue, reducing procedure time and enhancing safety by maintaining clear anatomical visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate tools are used for enucleation and morcellation, then each function can be performed with a specialized tool, but the procedure time increases and the risk of anatomical damage increases
Solution Approach 1:
The patent combines the laser fiber for enucleation and the morcellator for tissue fragmentation into a single integrated device. The laser fiber is positioned within the morcellator housing, allowing both functions to be performed through one instrument insertion, eliminating the need to switch between separate tools and reducing procedure time while maintaining safety through coordinated design of both functions in one system.
Solution Approach 2:
The integrated device serves multiple functions: the laser fiber performs enucleation of prostate tissue while the morcellator simultaneously or sequentially fragments the tissue for removal. This multi-functional approach allows a single device to replace what would traditionally require separate specialized instruments, reducing the number of procedural steps and associated risks.
2Reliability
If multiple separate tools are used for enucleation and morcellation, then each function can be performed with a specialized tool, but the device complexity increases
Solution Approach 1:
The patent integrates the laser fiber delivery system within the morcellator housing, creating a single unified device that performs both enucleation and tissue fragmentation functions. This merging eliminates the need to manage multiple separate tools during the procedure, reducing operational complexity while maintaining the specialized functions of each component through their coordinated integration.
3Reliability
If resected tissue is moved to the bladder for later removal, then complete tissue removal can be achieved, but the field of vision becomes obstructed increasing the risk of anatomical damage
Solution Approach 1:
The integrated device allows for preliminary fragmentation of the enucleated prostate tissue immediately at the surgical site using the morcellator, before the tissue is moved to the bladder. By breaking down the tissue in situ, the procedure maintains clear visibility of anatomical structures throughout the process, eliminating the period where large tissue masses would obstruct the surgical field while still achieving complete tissue removal.
