Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hemostatic clips used in medical procedures face challenges with small clipping force and unreliable positioning, making them troublesome to install and disassemble, which complicates the surgery process.
Innovation Solution
A hemostatic clip design featuring a first sleeve with position-limiting parts that cooperate in a specific way to fix the clip body axially, enhancing clipping stability by limiting degrees of freedom and ensuring secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple hemostatic clip design is used, then the device structure is simple, but the clipping force is small and positioning is unreliable
Solution Approach 1:
The hemostatic clip is divided into multiple functional segments: a first sleeve with a first position-limiting part, a clip body with a second position-limiting part and third position-limiting part, and a position-limiting member with a fourth position-limiting part. This segmentation allows each component to perform its specific function while working together to achieve reliable positioning and sufficient clipping force without excessive overall complexity.
Solution Approach 2:
The patent introduces multiple position-limiting parts distributed in different spatial dimensions and orientations. The first position-limiting part limits the second position-limiting part in one direction, while the fourth position-limiting part limits the third position-limiting part in an opposite direction. This multi-dimensional positioning approach ensures reliable axial fixation of the clip body on the first sleeve.
2Device complexity
If a simple hemostatic clip design is used, then the device structure is simple, but the installation and disassembly become troublesome
Solution Approach 1:
The clip body is designed to be movably provided in the first sleeve, allowing dynamic movement during installation and disassembly operations. The position-limiting parts provide guidance and control for this movement, enabling smooth insertion and removal while maintaining stable positioning during the clipping operation. This dynamic design facilitates easier installation and disassembly without compromising structural simplicity.
3Stability of the object's composition
If position-limiting parts are added to fix the clip body axially, then the clipping stability is improved, but the device complexity increases
Solution Approach 1:
The position-limiting functionality is merged into the existing structural components of the hemostatic clip. The first position-limiting part is integrated into the first sleeve, the second and third position-limiting parts are integrated into the clip body, and the fourth position-limiting part is integrated into the position-limiting member. This merging approach provides axial fixation and improved clipping stability without adding separate, independent positioning mechanisms, thereby minimizing the increase in device complexity.

AI summary
A hemostatic clip may include a first sleeve provided with a first position-limiting part at its head end; a clip body movably provided in the first sleeve and provided with a second position-limiting part and a third position-limiting part spaced apart from each other, and the second position-limiting part selectively cooperating with the first position-limiting part in a position-limiting way; and a position-limiting member provided on the first sleeve and provided with a fourth position-limiting part. The fourth position-limiting part cooperates with the third position-limiting part in a position-limiting way when the second position-limiting part cooperates with the first position-limiting part in a position-limiting way. A tissue clipping device may include an applying device and the hemostatic clip.
