Multi-Function Endoscopic End-Effector for Fewer Device Exchanges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing endoscopic procedures require multiple devices with single functionalities, increasing invasiveness and prolonging surgical time due to the need for frequent device exchanges.
Innovation Solution
A minimally invasive medical device with an elongate member and end-effector featuring multiple arms, jaws, and integrated tools such as cutting elements, suction, and irrigation, allowing for simultaneous manipulation of tissues through a single device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple single-functionality devices are used during surgical procedures, then each device can perform its specific function, but the number of device exchanges increases and surgical time is prolonged
Solution Approach 1:
The end-effector is designed with multiple functional capabilities including grasping, cutting, cauterizing, and suction all integrated into a single device. The distal end includes a grasper with cutting elements that can be actuated alongside suction and irrigation capabilities, allowing one device to replace multiple specialized tools during surgery.
Solution Approach 2:
Multiple previously separate surgical tools are merged into a single end-effector assembly. The grasper, cutting elements, cauterizing features, and suction/irrigation systems are combined in one integrated device that can be manipulated through a single insertion site, eliminating the need to exchange between multiple devices.
2Adaptability or versatility
If multiple single-functionality devices are used during surgical procedures, then each device can perform its specific function, but the invasiveness of the procedure increases
Solution Approach 1:
The end-effector consolidates multiple functions into a single device that can be introduced through one incision or natural opening. By integrating grasping, cutting, cauterizing, and suction capabilities in one tool, the number of incisions required is reduced, thereby minimizing tissue trauma and improving patient outcomes.
3Adaptability or versatility
If multiple devices are exchanged during surgery, then different functionalities can be provided, but the precision and efficiency of the procedure decreases
Solution Approach 1:
Multiple functional capabilities are merged into a single end-effector with integrated control mechanisms. The cutting elements, grasper, cauterizing features, and suction/irrigation systems can all be actuated through a unified control system at the proximal end, maintaining surgical precision while providing diverse functionalities without the need to exchange devices.

AI summary
A medical device including an elongate member having a proximal end, a distal end, and a lumen extending therebetween. The medical device may further include an end-effector disposed at the distal end of the elongate member. The end-effector may include a plurality of arms pivotally connected to one another, wherein each arm includes a tissue-contacting surface, a first portion of the tissue-contacting surface including a plurality of ridges configured to grasp tissue. Further, the tissue-contacting surface may include a channel oriented substantially parallel to a longitudinal axis of the medical device.
