Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional multi-hemostatic clips for endoscopes face challenges in ensuring precise combination, free rotation, and repeated opening and closing functions under extreme bending conditions due to interference and jamming of clip units in the conveying pipe, leading to reduced operation efficiency and increased risk.
Innovation Solution
A multi-processing device for endoscopes featuring a conveying component with a control member and limit parts that allow smooth movement and repeated opening/closing of processing units by using a first limit part that deforms under external force and a second limit part that expands or contracts radially to avoid interference with the conveying pipe.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple clip units are arranged in a conveying pipe, then the quantity of processing units is increased, but the rear clip unit may be stuck due to interference from the front clip unit
Solution Approach 1:
The conveying pipe is divided into multiple segments along its length, with each segment capable of independent radial expansion and contraction. This segmentation allows each section to independently accommodate and release clip units, preventing interference and jamming between adjacent clip units while enabling multiple units to be conveyed simultaneously
2Quantity of substance
If multiple clip units are accommodated in the conveying pipe, then the quantity of processing units is increased, but they cannot smoothly pass through a curved conveying pipe cavity in extreme bending status
Solution Approach 1:
The conveying pipe employs a dynamic structure where each segment can independently change its radial dimensions. During extreme bending, the segments can radially expand to accommodate the curved path and contract to maintain a compact profile, enabling smooth passage through curved cavities while carrying multiple clip units
3Quantity of substance
If multiple clip units are accommodated in the conveying pipe, then the quantity of processing units is increased, but they cannot realize stable repeated opening and closing after the clip unit extends out of the conveying pipe
Solution Approach 1:
The conveying pipe segments perform preliminary actions by radially expanding to push clip units outward and then contracting to release them in a controlled sequence. This preliminary expansion and contraction action ensures that each clip unit is properly positioned and released with sufficient force to achieve stable repeated opening and closing operations after extending from the conveying pipe
4Length of moving object
If the diameter of endoscopic instrument channel is between 2.8 mm and 3.2 mm, then the device is minimally invasive, but precise combination and free rotation of processing units is difficult under extreme bending
Solution Approach 1:
The conveying pipe is segmented into multiple independent sections, each capable of radial expansion and contraction. This segmentation allows each section to independently adjust to maintain precise combination and enable free rotation of processing units, even when the overall pipe diameter is constrained to 2.8-3.2 mm for minimally invasive application
Solution Approach 2:
The dynamic radial adjustment capability of each segment allows the conveying pipe to adapt its local geometry in real-time, maintaining precise combination and free rotation of processing units despite the constrained overall diameter and extreme bending conditions in the minimally invasive range

AI summary
The present disclosure provides a multiple-processing device for an endoscope. The multi-processing device may comprise a plurality of processing units, a conveying component, and an operation component. The processing units may include a capsule body and clamping arms. A proximal end of the capsule body may be provided with a first limit part that may be available for deformation or failure under an external force. The distal end of a conveying pipe of the conveying component and/or the proximal end of the capsule body may be provided with a second limit part configured to expand and contract along a radial direction of the conveying pipe. The multiple-processing device not only enhances the combination between the capsule body and the conveying pip, so as to control the opening and closing of the clamping arms, but also prevents the processing units from interfering or jamming the inner wall of the conveying pipe due to the expanded first limit part, which can ensure the smooth movement of the processing units in the conveying pipe, so that the processing units can be effectively repeatedly opened and closed before being released. The present disclosure also provides a use method of a multi-multi-processing device for an endoscope.
