Free Scar Trocar Segmentation for Minimal Tissue Trauma
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional minimally invasive surgical instruments often cause tissue damage and scarring due to their thick outer diameter and the need for large incisions, leading to unwanted scars, which can impact the aesthetics of patients, especially in cosmetic procedures.
Innovation Solution
A surgical device comprising multiple elongated rods with a thin outer diameter and a free scar trocar system that allows for minimal trauma insertion through a plurality of lumens, minimizing tissue damage and scarring, and a method of using these rods to perform surgery with interchangeable components for various surgical functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traditional minimally invasive surgical instruments with thick outer diameter are used to provide access lumen to surgical site, then surgical access is achieved, but tissue damage and scarring occur
Solution Approach 1:
The surgical instrument is divided into multiple separate cannulas (first cannula, second cannula, third cannula) instead of a single thick trocar. Each cannula has a thin outer diameter and can be inserted through separate small incisions, collectively providing the necessary access lumens while minimizing tissue damage and scarring at each insertion site.
Solution Approach 2:
The invention transitions from a single-point access (one thick trocar) to a multi-point access system (multiple thin cannulas). By distributing the access function across multiple dimensions (multiple insertion sites), the system achieves the same surgical access capability while reducing the trauma at each individual site, enabling scar-free or minimal scar healing.
2Quantity of substance
If large diameter conventional trocar is used to puncture tissue for surgical access, then access lumen is provided, but scarring and keloids are caused
Solution Approach 1:
The single large-diameter trocar is segmented into multiple small-diameter cannulas. Each cannula creates a small puncture that heals without scarring, while collectively they provide the necessary access lumens for surgical instruments. This segmentation eliminates the need for large punctures that cause scarring and keloids.
Solution Approach 2:
The outer diameter parameter of the access instruments is dramatically reduced from thick to thin. By changing this critical dimension, the cannulas can be inserted through tiny incisions that heal by first intention without visible scarring, while still providing adequate lumens for surgical tool passage through careful lumen design.
3Quantity of substance
If tissue incision with scalpel blade is used to access surgical site, then surgical access is obtained, but tissue damage and scarring result
Solution Approach 1:
The invention extracts and eliminates the scalpel blade cutting function from the access process. Instead of using a scalpel to incise tissue, the system uses thin cannulas that are inserted through minimal punctures or natural openings, taking out the harmful cutting action while preserving the essential access function.
Solution Approach 2:
The thin cannulas serve as intermediaries that provide surgical access without requiring large incisions. These cannulas can be inserted through tiny punctures created by fine needles or even through natural body openings, acting as mediators that bridge the external surgical tools to the internal surgical site without causing significant tissue disruption.
4Productivity
If minimally invasive surgical instruments are used to perform surgery, then surgical procedures can be performed, but scars are produced that alter body aesthetics
Solution Approach 1:
The surgical access system is segmented into multiple thin cannulas that can be strategically positioned to avoid cosmetically sensitive areas or to create scars that are imperceptible. By distributing access points across multiple locations with tiny incisions, the system maintains full surgical capability while eliminating visible scarring that would affect body aesthetics.
Solution Approach 2:
The critical parameter change is in the outer diameter of the access instruments, reduced to extremely thin dimensions. This parameter change enables insertion through incisions so small that they heal without visible scars, while the internal lumen design ensures adequate space for surgical tools, maintaining productivity without aesthetic compromise.
