Surgical Instrument Temporary Stabilization for Bone Surgery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical instruments used to protect soft and vascular tissues during bone surgery are not adequately stabilized, leading to potential movement during interventions and compromised protection.
Innovation Solution
A surgical instrument with a temporary stabilization portion that secures the instrument to the bone, ensuring stability and optimal protection during bone cutting or drilling, featuring through orifices for implantable organs and guide means for bone surgery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protective surgical instrument is positioned subcutaneously between the bone and soft/vascular tissues, then tissue protection is improved, but the instrument may move during manipulations and fail to maintain its protective role
Solution Approach 1:
The patent applies preliminary action by equipping the protective instrument with a temporary stabilisation portion that includes through orifices for receiving pins or screws before the main surgical intervention begins. This allows the instrument to be pre-stabilized to the bone surface, ensuring it remains in the correct protective position throughout subsequent manipulations and bone cutting operations.
Solution Approach 2:
The patent uses an intermediary element (the temporary stabilisation portion with through orifices) that mediates between the protective instrument and the bone. This intermediary structure allows for temporary anchoring using pins or screws, providing stable fixation without requiring permanent implantation, thus resolving the contradiction between maintaining protective position and avoiding permanent bone modification.
2Stability of the object's composition
If the protective instrument is stabilized to the bone, then positioning stability is improved, but the complexity of the device increases
Solution Approach 1:
The patent applies segmentation by dividing the protective instrument into distinct functional portions: a protective portion for tissue protection, a gripping portion for handling, and a temporary stabilisation portion with through orifices for anchoring. This modular segmentation allows each component to perform its specific function independently, adding stabilization capability without requiring complete redesign of the entire instrument.
Solution Approach 2:
The patent applies local quality by adding the temporary stabilisation portion only where needed on the instrument body, rather than making the entire instrument more complex. The through orifices are strategically positioned on the stabilisation portion to receive anchoring elements, providing localized fixation functionality that maintains overall device simplicity while achieving the desired positioning stability.
3Stability of the object's composition
If through orifices are added for receiving pins or screws, then positioning stability is improved, but the device complexity increases
Solution Approach 1:
The patent applies universality by designing the temporary stabilisation portion with through orifices that can accommodate multiple types of anchoring elements (pins, screws, or other temporary fixation devices). This multi-functional design allows the same structural feature to work with various securing methods, providing versatile temporary fixation capability without requiring separate specialized components for each anchoring type.

AI summary
Disclosed is a surgical instrument suitable for protecting tissue during bone surgery, for example when cutting and/or drilling a bone. The surgical instrument includes a protective portion intended to be positioned in a protective subcutaneous position between the tissue to be protected and a bone. The surgical instrument further includes a temporary stabilization portion which is designed to temporarily secure the surgical instrument to the bone, in the protective position.
