Tissue Manipulation Device With Movable Fabric Track
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surgical procedures, especially laparoscopic and endoscopic ones, face challenges in moving tissue due to space constraints and the remoteness of surgical tools from the surgeon, making it difficult to effectively manipulate tissue or surgical devices within constrained and remote locations.
Innovation Solution
The development of a tissue moving device featuring a substantially rigid insertion body with porous fabric material extending along its outer surface, allowing for relative movement of tissue sites by contacting and moving the fabric along predetermined paths, facilitated by an actuator mechanism that enables selective movement of the fabric relative to the body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional surgical tools are used in laparoscopic and endoscopic procedures, then the surgeon can perform surgical operations, but the remoteness of the surgical tool from the surgeon and space constraints make it difficult to move tissue effectively
Solution Approach 1:
A fabric track is introduced as an intermediary element between the rigid insertion body and the tissue. The fabric track extends along the outer surface of the insertion body and can be moved relative to it, serving as a mediator that transfers motion from the actuator to the tissue. This allows the surgeon to manipulate tissue indirectly through the fabric track, overcoming the remoteness issue while maintaining operational ease.
Solution Approach 2:
The fabric track is designed to be movable relative to the rigid insertion body, creating a dynamic system. The actuator mechanism enables selective movement of the fabric track along predetermined paths, allowing the tissue manipulation device to adapt its configuration during the procedure. This dynamic capability enhances ease of tissue movement without requiring complex overall device structure.
2Adaptability or versatility
If the surgical device is located in constrained spaces remote from the surgeon, then minimally invasive procedures can be performed, but movement of the surgical device and tissue manipulation becomes challenging
Solution Approach 1:
The device is segmented into distinct functional components: a rigid insertion body for structural support and navigation to the target site, and a movable fabric track for tissue manipulation. This segmentation allows the insertion body to be optimized for accessing constrained spaces while the fabric track provides the necessary adaptability for tissue manipulation, resolving the contradiction between adaptability and ease of operation.
Solution Approach 2:
The fabric track serves as a mediator that enables tissue manipulation in constrained spaces. By extending along the outer surface of the insertion body and being movable relative to it, the fabric track can adapt to the limited space available in laparoscopic and endoscopic procedures while still allowing effective tissue movement through actuator-driven motion along predetermined paths.
3Ease of operation
If fabric material is moved along the outer surface of the insertion body to manipulate tissue, then tissue movement is enabled, but the fabric must maintain frictional contact with both the tissue and the insertion body
Solution Approach 1:
The fabric track is designed with specific local properties to optimize frictional contact. The material selection and surface characteristics of the fabric track are tailored to provide sufficient friction with the tissue for effective manipulation, while its interaction with the insertion body is designed to allow controlled movement. This local quality optimization enables ease of tissue manipulation without requiring excessive overall frictional strength.
