Modular Anastomotic Ring Applier with Removable Distal Portion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical devices for applying anastomotic rings in the digestive system do not allow for the easy replacement of distal portions, leading to inefficiencies and increased costs due to the need for replacing the entire device, rather than just the disposable components.
Innovation Solution
A surgical instrument with a modular design where the distal portion, containing the ring deployment mechanism, is selectively removable from the proximal portion, enabling the replacement of only the distal portion while keeping the proximal portion intact, allowing for reuse or reconfiguration with different distal ends.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the entire surgical device is replaced after use, then reliability and sterility are ensured, but cost and waste increase significantly
Solution Approach 1:
The surgical device is divided into two distinct segments: a reusable proximal portion (handle) and a disposable distal portion (ring deployment mechanism). This segmentation allows the distal portion to be discarded after a single use while the proximal portion can be sterilized and reused, thereby ensuring reliability and sterility while significantly reducing material waste and cost.
2Reliability
If the entire surgical device is replaced, then functionality is ensured, but cost increases
Solution Approach 1:
The device is segmented into reusable and disposable portions, allowing the expensive handle to be reused while only the less expensive distal portion is replaced, thereby maintaining functionality while reducing financial cost.
Solution Approach 2:
The distal portion (ring deployment mechanism) is designed as a disposable, single-use component that is replaced after each procedure. This allows the more expensive proximal portion to be reused multiple times, reducing overall financial cost while ensuring that a fresh, functional distal portion is used for each procedure.
3Adaptability or versatility
If the distal portion is made removable, then versatility and cost-effectiveness improve, but device complexity increases
Solution Approach 1:
The device is segmented into separable proximal and distal portions with standardized coupling interfaces. This segmentation enables versatility by allowing different distal portions to be attached to the same handle, while the coupling mechanism is designed to be simple and intuitive, minimizing the increase in structural complexity.
Solution Approach 2:
The proximal portion (handle) is designed with a universal coupling interface that can accommodate various types of distal portions. This universality allows the same handle to be used with different ring deployment mechanisms or other distal components, thereby improving device versatility without significantly increasing the complexity of the handle itself.

AI summary
A surgical instrument that is operable to deploy an anastomotic ring device comprises a proximal portion and a distal portion. The distal portion comprises a ring deployment mechanism, which is configured to receive and deploy an anastomotic ring. The proximal portion comprises a mechanism that is operable to remotely actuate the ring deployment mechanism. The distal portion is removable from the proximal portion. The distal portion may be selectively engaged with the proximal portion by a series of annular flanges and clamp arms that are configured to engage the annular flanges. The ability to remove the distal portion of the instrument permits the replacement of the ring deployment mechanism without requiring the replacement of the instrument in its entirety.
