Slidable Inner Tube Surgical Tool Insertion Aid
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional surgical tool insertion aids limit the diameter and number of inner tubes, restricting the insertion of larger diameter tools and simultaneous use of multiple tools.
Innovation Solution
A surgical tool insertion aid with slidable inner tubes and guide members, allowing for adjustable diameters and numbers of inner tubes, enabling independent exchange of tools during surgery, and featuring wire members for bending and degassing prevention mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple inner tubes with fixed diameters are used, then the insertability of surgical tools is improved, but the adaptability to different tool sizes and numbers is limited
Solution Approach 1:
The inner tubes are designed to be slidable relative to the insertion aid body through guide members, allowing the configuration of inner tubes to be dynamically adjusted during surgery. This enables the system to adapt to different numbers and sizes of surgical tools while maintaining proper insertion and positioning.
Solution Approach 2:
The insertion aid is segmented into multiple independent inner tubes that can be individually adjusted, inserted, or removed. Each inner tube can be independently positioned along the guide members, allowing flexible configuration to match the specific surgical needs and tool requirements.
2Device complexity
If the number of inner tubes is fixed, then the structure is simplified, but the ability to simultaneously use multiple surgical tools is restricted
Solution Approach 1:
The system allows dynamic adjustment of the number of inner tubes in use. While the insertion aid can accommodate multiple inner tubes, the actual number used can be adjusted based on surgical requirements, providing versatility without requiring a permanently complex multi-tube structure.
3Stability of the object's composition
If inner tubes are fixed in position, then the structural stability is improved, but the ability to exchange surgical tools independently is reduced
Solution Approach 1:
The inner tubes are designed with sliding capability along the guide members, allowing them to be independently moved, exchanged, or repositioned while maintaining structural stability when in use. This dynamic positioning enables tool exchange without compromising the overall structural integrity of the insertion aid.
Solution Approach 2:
Each inner tube is an independent, separable component that can be individually exchanged while other tubes remain in place. The guide members provide stable guidance for each tube, ensuring that independent exchange does not affect the stability or positioning of other tubes.

AI summary
A surgical tool insertion aid is provided which enables simultaneous use of multiple surgical tools, as well as the independent exchange of a surgical tool during surgery. A tubular surgical tool insertion aid 1 aids insertion of surgical tools 11 and 13 into the body, and includes: an inner tube 2 into which the surgical tools 11 and 13 are insertable, and which is insertable into the surgical tool insertion aid 1; and a plurality of guide members 3 which are extended in the axial direction from a distal end side to a proximal end side in the inner peripheral surface of the surgical tool insertion aid 1. The inner tube 2 includes, on the outer peripheral surface thereof, an engaging member 4 that engages with the guide member 3 to be made slidable.
