Anastomotic Device Fluid Insufflation for Hollow Tissue
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical stapling devices for circular anastomosis and hemorrhoid treatment face challenges in efficiently inserting and positioning instruments within hollow organs, particularly in the rectum, due to the lack of effective insufflation methods that prevent injury and ensure precise stapling and cutting.
Innovation Solution
An anastomotic device with a fluid supply channel and anvil assembly that insufflates the hollow tissue organ with an inflation fluid, allowing for easier insertion and facilitating stapling by creating a friction-free environment, while also enabling the stapling and cutting of tissue with a knife mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If surgical stapling devices are inserted into hollow organs without insufflation, then the insertion process is difficult and may cause tissue injury, but adding insufflation equipment increases device complexity
Solution Approach 1:
The patent combines the insufflation function with the stapling device by integrating a fluid supply channel and outlet into the head assembly. This merging of functions allows the device to both insufflate the hollow organ and perform stapling/cutting operations, eliminating the need for separate insufflation equipment and reducing overall system complexity.
Solution Approach 2:
The patent introduces inflation fluid as an intermediary substance that facilitates the insertion process. The fluid acts as a mediator between the device and tissue, creating a friction-free environment that enables easier passage of the device through the hollow organ while preventing tissue injury.
2Reliability
If insufflation fluid is discharged during insertion, then tissue injury is prevented and insertion is facilitated, but precise control of fluid discharge timing and location is difficult
Solution Approach 1:
The patent implements local quality by positioning the fluid outlet specifically at the distal end of the head assembly, adjacent to the stapling mechanism. This localized fluid discharge ensures that insufflation occurs precisely where needed during the stapling operation, enabling controlled inflation of the hollow organ at the treatment site while maintaining precision in fluid delivery.
Solution Approach 2:
The patent applies preliminary action by providing the fluid supply channel that extends between the handle assembly and head assembly, with the outlet positioned at the distal end. This pre-configured fluid delivery system is ready to discharge inflation fluid at the precise moment and location needed during insertion and stapling operations, ensuring injury prevention without compromising control.
3Productivity
If a friction-free environment is created through insufflation, then stapling and cutting operations are facilitated, but the requirement for fluid supply infrastructure increases
Solution Approach 1:
The patent merges the fluid supply infrastructure with the stapling device by integrating the fluid supply channel, outlet, and insufflation function into the head assembly. This combination allows the creation of a friction-free environment for stapling and cutting operations while incorporating all necessary fluid delivery components into a single integrated device, reducing the need for external infrastructure.
