Wire Loop Retractor for Adjustable Surgical Field Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for holding a surgical incision open during operations are costly, risk damage to the incision site, reduce workability, and fail to adapt to changing surgical situations, as they require manual assistance, large systems, or insufficient force to maintain the surgical field.
Innovation Solution
A retractor with a belt-shaped body made of wire and a connecting part that forms a loop, resisting the force closing the incision, allowing for adjustable loop sizes and shapes, and featuring hooks or increased friction to prevent movement, reducing labor costs and improving workability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If surgical assistants hold and pull rod-shaped medical devices with hooked front ends to hold the surgical incision open, then the surgical field can be maintained, but labor costs increase and the incision site may be damaged
Solution Approach 1:
The retractor is designed to maintain the surgical field independently without requiring surgical assistants to hold or pull it. The device's structure with its belt-shaped body and connecting part allows it to function autonomously, eliminating the need for continuous manual intervention and reducing labor costs while maintaining reliable surgical field exposure.
Solution Approach 2:
The invention extracts the function of holding the surgical incision open from the surgical assistants and transfers it to the retractor device itself. By designing the retractor with self-sustaining structural features, the need for human operators to continuously manipulate the device is eliminated, thereby reducing labor costs while maintaining the surgical field.
2Reliability
If surgical assistants hold and pull rod-shaped medical devices with hooked front ends, then the surgical field can be maintained, but the incision site is more likely to be damaged
Solution Approach 1:
The retractor maintains the surgical field independently without requiring surgical assistants to manipulate it, thereby eliminating the harmful effect of manual pulling and hooking on the incision site. The device's autonomous functionality prevents repeated mechanical stress on the surgical wound.
Solution Approach 2:
The retractor is designed with structural features that prevent damage to the incision site before damage can occur. The belt-shaped body and connecting part configuration allows the device to maintain the surgical field without requiring forceful manipulation or hooking that could harm the surgical wound.
3Ease of manufacture
If arm support type retractors with poles and arms are used, then labor costs are reduced, but the system becomes complex and less flexible
Solution Approach 1:
The invention extracts and removes the unnecessary complex components (poles, arms, and other support structures) from the retractor system, retaining only the essential belt-shaped body and connecting part. This simplification maintains the ability to hold the surgical field open independently while eliminating the complexity and reducing flexibility that comes with oversized support structures.
Solution Approach 2:
The retractor is segmented into only the essential functional components: the belt-shaped body and the connecting part. By dividing the device into these minimal necessary elements, the design achieves simplicity while maintaining functionality, avoiding the complexity of integrated pole and arm structures.
4Reliability
If fixed-size retractors are used, then the surgical field can be maintained, but the retractor cannot adapt to changing surgical situations
Solution Approach 1:
The retractor incorporates dynamic adjustability through its connecting part, which allows the belt-shaped body to be configured in loops of various sizes and shapes. This dynamic configuration capability enables the device to adapt to different surgical situations and incision types while maintaining reliable surgical field exposure.
Solution Approach 2:
The retractor is designed with universal adaptability, allowing the same device to be configured for different surgical scenarios. The connecting part enables the belt-shaped body to form loops of various dimensions, making the retractor versatile for different incision sizes, shapes, and surgical requirements.

AI summary
Provided is a retractor that makes it possible to reduce operation costs, is less likely to cause damage to surgical incision sites, do not reduce workability, and also makes it possible to easily maintain the desired surgical field and to change the surgical field or widen or narrow the area of the surgical field, depending on the surgical situation. The retractor 1 for holding a surgical incision open and maintaining a surgical field during an operation includes a belt-shaped body A made of a wire; and a connecting part B that is provided at one end portion of the belt-shaped body A and capable of being connected to another end portion or an intermediate portion of the belt-shaped body A so that the belt-shaped body A can be formed into a loop of a desired size. The retractor 1 is so configured that when the belt-shaped body A is formed into a loop, the outer surface of the belt-shaped body A resists the force generated at the surgical incision and acting in such a direction as to close the surgical incision.
