Movable Surgical Staple for Bone Compression and Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical staples face challenges in providing effective force distribution and secure fixation in bone tissues, leading to potential leakage and instability during healing processes.
Innovation Solution
A surgical staple designed with a movable configuration between relaxed and opened states, featuring angled side sections and a curved middle section, allowing for secure insertion and improved bone compression through resilient properties and threaded apertures for enhanced retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If surgical staples are inserted into bone parts, then bone compression and fixation are achieved, but force distribution may be insufficient leading to leakage
Solution Approach 1:
The surgical staple is divided into multiple side sections (first side section, second side section, etc.) that can independently engage with bone parts. Each side section can be inserted into separate holes or slots in the bone, distributing the fixation force across multiple contact points rather than concentrating it at a single location, thereby improving force distribution while maintaining reliable fixation.
2Stability of the object's composition
If surgical staples are made rigid for stable fixation, then bone compression is improved, but adaptability to different bone configurations is reduced
Solution Approach 1:
The surgical staple incorporates movable or adjustable side sections that can transition between different positions or orientations. This dynamic design allows the staple to adapt to various bone configurations and anatomical variations while maintaining stable fixation once positioned. The side sections can be adjusted to accommodate different hole orientations, bone shapes, and compression requirements.
3Ease of operation
If surgical staples use simple insertion method, then ease of operation is improved, but retention and compression effectiveness are reduced
Solution Approach 1:
The surgical staple is designed with pre-formed side sections that are configured to engage with bone structures in a predetermined manner. The side sections may include pre-formed hooks, bars, or engagement features that automatically provide retention and compression upon insertion, eliminating the need for complex secondary fixation steps while maintaining high retention effectiveness.
4Manufacturing precision
If surgical staples have fixed configuration, then manufacturing precision is improved, but ability to provide optimal force distribution is reduced
Solution Approach 1:
The surgical staple features side sections with different local properties - some sections may have varying thicknesses, material densities, or geometric characteristics optimized for specific functions. This allows different parts of the staple to provide different force distribution characteristics, with thicker or reinforced sections providing greater force where needed and thinner sections providing flexibility in other areas, achieving optimal force distribution while maintaining manufacturing precision.

AI summary
A surgical staple includes a middle section extending between a first end and a second end; a first side section extending from the first end and being configured to be inserted into a bone; and a second side section extending from the second end and being configured to be inserted into a bone; wherein the first side section and the second side section cantilever away from the middle section, and the surgical staple is selectively movable between a relaxed configuration where the first side section and the second side section cantilever away from the middle section, and an opened configuration where the first side section and the second side section are substantially parallel to each other.
