Expandable Tissue Container With Guarded Cutting for Malignancy Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing minimally invasive tissue removal techniques, particularly power morcellation, pose a risk of spreading occult malignancies during the removal of large tissue specimens, necessitating safer and more efficient methods for capturing and removing tissue specimens, especially in gynecological procedures like hysterectomies.
Innovation Solution
A system and method involving an expandable tissue container with a tissue cutter and guard, deployable through the vagina, allowing for safe containment and cutting of tissue specimens within the body, using a cannula and grasper for specimen manipulation, and tensioning mechanisms for efficient removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If power morcellation is used to remove large tissue specimens through minimally invasive approaches, then the advantages of reduced pain, lower infection risk, and shorter recovery times are achieved, but the risk of spreading occult malignancies increases
Solution Approach 1:
A sealed containment bag is introduced as an intermediary between the tissue specimen and the surgical field. The bag is deployed into the body cavity, the tissue specimen is placed inside, and then the bag is removed through the body cavity without direct exposure of the specimen to the surrounding environment, thereby preventing potential spread of malignancy while maintaining minimally invasive access
Solution Approach 2:
A flexible, sealed containment bag is used to enclose the tissue specimen. The bag can be inflated to create a sealed chamber that isolates the specimen from the external environment during removal, preventing contamination while allowing minimally invasive surgical access
2Ease of operation
If manual or power morcellation is performed to process large tissue specimens, then the specimens can be removed through small incisions, but the operative time increases due to multiple passes required
Solution Approach 1:
The containment bag is deployed and prepared in advance within the body cavity before the tissue specimen is introduced. This preliminary setup allows for continuous, uninterrupted removal of the specimen through the bag in a single operation, eliminating the need for multiple passes and reducing operative time
Solution Approach 2:
The system enables continuous removal of the tissue specimen through the containment bag in a single operational sequence. The bag remains inflated and sealed throughout the process, allowing uninterrupted extraction without requiring multiple passes or interruptions, thereby reducing total operative time
3Reliability
If traditional surgical techniques are used to remove tissue specimens, then complete removal can be achieved, but patient exposure to anesthesia and surgical trauma increases
Solution Approach 1:
The tissue specimen is segmented into smaller pieces within the containment bag during the removal process. This segmentation allows the specimen to be extracted through smaller incisions and reduces the overall surgical trauma required, while still achieving complete removal of the original specimen
Solution Approach 2:
The flexible containment bag allows the tissue specimen to be compressed and segmented within the bag while maintaining a sealed environment. This enables complete removal of the specimen through minimal incisions, reducing surgical trauma and anesthesia exposure while ensuring reliable removal
