Adhesive Pad Surgical Access Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical access stabilization methods, particularly in minimally invasive procedures, are constrained by rigid connectors that limit the range of motion and flexibility of surgical access devices, often requiring additional stationary objects and dictating the flow of the procedure rather than allowing surgeon expertise to guide it.
Innovation Solution
A surgical access stabilization device comprising a pad with an adhesive surface and a locking mechanism that allows for adjustable positioning and securement of a surgical access device relative to the patient's skin, enabling translational, rotational, and angular movement, thereby providing greater flexibility and ease of adjustment during procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If rigid mechanical arm connectors are used to stabilize surgical access devices, then stability and support are improved, but range of motion and flexibility are restricted
Solution Approach 1:
The patent replaces rigid mechanical connectors with a dynamic system consisting of an adhesive pad that can be repositioned and a locking mechanism that can be adjusted to different positions. This allows the surgical access device to be stabilized while maintaining the ability to change its position and orientation during the procedure, resolving the contradiction between stability and range of motion.
Solution Approach 2:
The invention substitutes the mechanical arm connector system with an adhesive-based fixation system combined with a locking mechanism. This replacement eliminates the rigid mechanical constraints while providing sufficient stabilization through adhesion and selective locking, thereby improving both stability and flexibility.
2Stability of the object's composition
If rigid mechanical arm connectors are used to stabilize surgical access devices, then positional stability is improved, but ease of adjustment is reduced
Solution Approach 1:
The adhesive pad can be easily removed and repositioned on the patient's body, and the locking mechanism can be adjusted to different positions along the pad. This dynamic system provides positional stability when locked while maintaining ease of adjustment when needed, resolving the contradiction between stability and operability.
Solution Approach 2:
The adhesive pad can be discarded (removed) and reapplied at different positions during the procedure. This allows for easy adjustment of the surgical access device position without being constrained by a fixed mechanical connector, thereby improving ease of operation while maintaining stability when required.
3Stability of the object's composition
If additional stationary objects are used to stabilize surgical access devices, then stabilization support is improved, but device complexity and space requirements increase
Solution Approach 1:
The invention combines the adhesive pad and locking mechanism into an integrated stabilization system that attaches directly to the patient's body. This eliminates the need for separate stationary objects like mechanical arm connectors and support structures, reducing device complexity while maintaining stabilization support.
Solution Approach 2:
The patent extracts the stabilization function from complex mechanical connector systems and implements it through a simpler adhesive-based system. By removing the unnecessary mechanical components and support structures, the invention reduces device complexity while preserving the essential stabilization function.
