Clip Instrument Segmentation for Endoscopic Clamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current clip instruments used with flexible endoscopes face challenges in maintaining effective clamping and minimizing tissue damage during endoscopic procedures, as they often require larger sizes to accommodate tissue clamping, which can lead to increased invasiveness and reduced operational space within the body.
Innovation Solution
A clip instrument with a clip arm and locking mechanism that includes two clips and extending parts, allowing for a closed state to be maintained within the body through a locking part, enabling improved clamping effectiveness while allowing the extending parts to be removed, thus reducing the instrument's size and providing more operational space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the clip instrument uses a larger size to accommodate tissue clamping, then the clamping effectiveness is improved, but the invasiveness increases and operational space within the body is reduced
Solution Approach 1:
The clip instrument comprises a clip arm and a locking part, where the clip arm includes at least two clips and at least two extending parts releasably connected to the clips. The extending parts serve as temporary delivery mechanisms that can be removed after deployment, leaving only the compact clip arm structure within the body.
2Reliability
If the clip instrument uses a larger size to accommodate tissue clamping, then the clamping effectiveness is improved, but the operational space within the body is reduced
Solution Approach 1:
The instrument structure is segmented into deployable extending parts and a compact retained clip arm, enabling effective clamping functionality to be achieved temporarily during delivery while minimizing the permanent occupancy space within the body
Solution Approach 2:
The extending parts are designed to be discarded after serving their delivery function. These parts are releasably connected to the clips and can be removed from the body after the clips are deployed and locked into the closed state, thereby recovering operational space for subsequent surgical procedures
3Object-affected harmful factors
If the extending parts are removed from the body, then the operational space is increased and impact on the body is reduced, but the clamping effectiveness may be compromised
Solution Approach 1:
The locking part is activated in advance to secure the clips in the closed state before the extending parts are removed. This preliminary locking action ensures that clamping effectiveness is maintained and will not be compromised when the extending parts are discarded
Solution Approach 2:
The extending parts are designed to be discarded after serving their delivery function, while the locking mechanism ensures clamping effectiveness is preserved. The releasable connection allows the extending parts to be removed after the clips are locked into position

AI summary
Embodiments of the present disclosure provide a clip instrument. The clip instrument may include a clip arm and a locking part. The clip arm may include at least two clips for clamping at least one tissue and at least two extending parts releasably connected to the at least two clips, respectively. The clip arm has an open state and a closed state, wherein the at least two clips are spaced apart from each other when the clip arm is in the open state to form a space for clamping the at least one tissue, and the at least two clips are close to each other when the clip arm is in the closed state. The locking part may be configured to lock two clips of the at least two clips when a distance between the two clips is less than a preset distance.
