Anastomosis Background Device with Drainage and Guide Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During anastomosis surgery, poor visibility and high dexterity requirements are exacerbated by irrigation, which reduces contrast between the vessel and surgical site, making it difficult for surgeons to distinguish details and perform suturing effectively.
Innovation Solution
An anastomosis background device with a base for placement on the surgical site, featuring a drainage system, suction port, and guide structure to improve visibility and reduce dexterity needs, including clamps for vessel attachment and a guide structure to aid suturing, with removable components and color contrast to enhance visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If irrigation is used during surgery, then the surgical site is kept clean and temperature controlled, but visibility and contrast at the surgical site deteriorate
Solution Approach 1:
A background device is introduced as an intermediary element between the irrigation fluid and the surgical field. This device provides a contrasting backdrop that enhances visibility of the vessel and surgical site while allowing irrigation to continue. The background device acts as a mediator that converts the harmful effect of irrigation (reduced contrast) into a beneficial situation (maintained visibility through contrast enhancement).
Solution Approach 2:
The background device utilizes color contrast principles by providing a colored background (typically blue or green) that contrasts with the natural colors of the surgical site and vessel. This color differentiation enhances the surgeon's ability to distinguish anatomical structures despite the presence of irrigation fluid, directly addressing the visibility problem while maintaining irrigation benefits.
2Manufacturing precision
If manual suturing is performed without assistance, then surgical precision can be maintained, but the complexity and time required for the procedure increases
Solution Approach 1:
The background device incorporates self-aligning features and guide structures that automatically position the vessel and suturing elements without requiring complex manual manipulation by the surgeon. The device performs part of the positioning and alignment work itself, reducing the skill burden and time required while maintaining precision. Features such as pre-marked suture paths and self-aligning clamp interfaces enable this self-service capability.
3Object-affected harmful factors
If irrigation continues during suturing, then surgical site cleanliness is maintained, but fluid accumulation interferes with the suturing process
Solution Approach 1:
The background device incorporates drainage channels and fluid evacuation pathways that extract excess irrigation fluid from the surgical site. By providing dedicated fluid removal channels, the device separates the irrigation function (cleaning) from the suturing function (dry field requirement), allowing both to proceed simultaneously without interference. The extracted fluid is directed away from the immediate surgical field.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device enhances visibility and contrast at the surgical site, automates fluid removal, and reduces the complexity of suturing by providing traction guidance, thereby simplifying the anastomosis procedure and reducing the surgeon's dexterity requirements.
