Endolumenal Anastomotic Ring Delivery via Guide Wire
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical methods for performing anastomoses, such as gastro-jejunostomy, are invasive and prone to complications due to the complexity of traditional open surgery and laparoscopic techniques, which are not suitable for endolumenal or endoscopic approaches, making it difficult to achieve safe and effective tissue approximation and ring connection.
Innovation Solution
A surgical instrumentation system involving a carrier member and anastomotic device that uses a guide wire loop to deliver and connect snap-connectable rings endoluminally or transluminally, reducing invasiveness by enabling controlled tissue approximation and reliable ring alignment and connection within the digestive tract.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional open surgery or laparoscopic techniques are used for anastomosis, then the anastomosis can be performed with established methods, but the invasiveness of the intervention is high and the risk of post-operative complications is increased
Solution Approach 1:
The patent introduces a guide wire as an intermediary element that traverses the tissue portions to be anastomosed, serving as a rail for delivering the anastomotic device. This mediator enables the transition from invasive external approaches to less invasive endolumenal approaches by providing a pathway through which the entire anastomotic system can be delivered endoscopically, thereby reducing invasiveness while maintaining anastomosis reliability
2Object-affected harmful factors
If endolumenal approach is used for anastomosis, then the invasiveness of the intervention is reduced, but the instrumentation and methods are not mature enough to assure adequate transportation of the ring device, controlled tissue approximation, and reliable alignment and connection of the rings
Solution Approach 1:
The anastomotic device is segmented into two separate rings that can be independently delivered and positioned on opposite tissue portions. This segmentation allows each ring to be independently controlled and positioned along the guide wire, enabling reliable alignment and connection at the anastomotic site while maintaining the benefits of the endolumenal approach
Solution Approach 2:
The guide wire is preliminarily positioned through both tissue portions to be anastomosed before the anastomotic rings are delivered. This preliminary action establishes a stable pathway and alignment reference that ensures controlled tissue approximation and reliable ring connection during the subsequent endolumenal procedure, addressing the immaturity of instrumentation concerns
3Ease of manufacture
If snap-connectable rings are used for anastomosis, then the alignment and connection of rings can be simplified, but the controlled tissue approximation and reliable alignment during deployment remain challenging with current endoscopic instrumentation
Solution Approach 1:
The anastomotic rings are designed with dynamic characteristics that allow them to be delivered in a compressed or collapsed state along the guide wire, then expanded or activated at the target site. This dynamic design enables controlled tissue approximation as the rings are pushed along the guide wire to the anastomotic site, while the snap-connectable mechanism simplifies the final connection, resolving the operational challenge
