Endoscopic Capsule Implanting Apparatus with Tissue Clip Anchoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current implanting apparatuses for capsule-like devices in hollow organs face challenges in safe insertion and secure anchoring, as existing devices are either too large for endoscopic delivery or lack effective anchoring mechanisms, leading to issues with signal damping due to proximity to biological tissue and the need for high output power for telemetry.
Innovation Solution
An endoscope-like implanting instrument with a tissue clip and clamping means that allows safe insertion and secure anchoring of capsule-like devices, featuring a holding and withdrawing mechanism with a manual actuation system and a clamping mechanism that applies a controlled clamping force, enabling easy detachment without compromising the endoscopic instrument's function.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If capsule-like devices are made small enough for endoscopic delivery, then they can be delivered through endoscope working channels, but they lack effective anchoring mechanisms in hollow organs
Solution Approach 1:
The capsule device is nested within the endoscopic implanting apparatus during delivery, allowing the small capsule to be transported through the endoscope's working channel. The capsule contains the telemetry system and is positioned within the clamping means for secure anchoring, effectively nesting one device within another to resolve the size-anchoring contradiction.
Solution Approach 2:
The tissue clip acts as an intermediary mechanism between the capsule device and the hollow organ wall. The clip provides the anchoring function that the small capsule itself cannot provide, mediating the connection between the deliverable capsule and the biological tissue to enable reliable fixation.
2Reliability
If capsule devices are made large enough to include effective anchoring mechanisms, then they can be securely anchored in hollow organs, but they are too large for endoscopic delivery
Solution Approach 1:
The system is segmented into two separate components: a small capsule device for telemetry and a separate tissue clip for anchoring. The capsule contains only the necessary telemetry system, while the anchoring function is provided by the tissue clip, allowing each component to be optimized independently for its specific function.
Solution Approach 2:
The tissue clip serves multiple functions: it provides secure anchoring to the hollow organ wall, holds the capsule device in position during delivery, and facilitates controlled release of the capsule. This multi-functionality allows the system to achieve reliable anchoring without increasing the capsule device size.
3Loss of information
If capsule devices are positioned close to biological tissue for telemetry, then signal transmission can be achieved, but signal damping occurs requiring high output power
Solution Approach 1:
The tissue clip acts as a mechanical intermediary that positions the capsule at an optimal distance from the tissue wall. This controlled positioning mediates between the need for close proximity (for signal transmission) and the need to avoid excessive signal damping, allowing effective telemetry without requiring high output power.

Function Achieved in This Case
Facilitates safe and secure implantation of capsule-like devices within hollow organs while maintaining the functionality of the endoscopic instrument, reducing signal damping effects and allowing for efficient telemetry without the need for high output power.
Implementation Method 1
The hinges 130 or the flexible moldings are preferably formed of spring-elastic straps which during opening the jaws 110, 120 store spring energy which results in a snapping of the jaws 110, 120 at a predetermined clamping force
Implementation Method 2
a clamping means (12, 13) comprising an open ring (12) which is elastic and can be radially expanded so that a predetermined clamping force is applied to the capsule-like device (3)

AI summary
An endoscope-like implanting instrument includes an endoscope cap having a holding and withdrawing mechanism for a tissue clip adapted to be slipped onto an expanding sleeve of the endoscope cap. The endoscope cap has a front groove opening at the front edge of the sleeve. A withdrawing thread radially crosses the front groove at an axial front cap portion. The instrument further includes a tissue grasping mechanism being shiftably inserted into the working channel for manually grasping and drawing the tissue inside the endoscope cap. A clamping mechanism is integrally arranged inside the endoscope cap in axial extension to the working channel, holding a capsule-like device and connected with the tissue clip via a thread, band or string such that the capsule-like device will be automatically detached by the grasping mechanism when being manually actuated for tissue grasping.
