Joint Positioning Device for Minimally Invasive Glenoid Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional surgical procedures for accessing internal tissue sites, such as orthopedic joints, often cause significant trauma and prolonged recovery due to extensive tissue dissection and require improved patient positioning for minimally invasive techniques.
Innovation Solution
A joint positioning device comprising a patient support, shoulder pole, and shoulder pad, which can be adjusted to properly position a patient's shoulder for endoscopic procedures, allowing access to the glenoid cavity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional surgical procedures are used to access internal tissue sites, then complete visualization and access can be achieved, but significant tissue trauma and prolonged recovery occur
Solution Approach 1:
The positioning device is configured to pre-position the patient's shoulder and arm in the optimal orientation before the procedure begins. The shoulder pad and support structure establish the correct anatomical alignment in advance, allowing the surgeon to immediately access the glenoid cavity without requiring extensive tissue dissection during the procedure itself.
Solution Approach 2:
The positioning device acts as an intermediary mechanism between the patient's anatomy and the surgical access requirements. By using the shoulder pad, support structure, and positioning components, the device mediates the relationship between the patient's body and the endoscopic instruments, enabling minimal invasive access while maintaining complete visualization capability.
2Reliability
If extensive tissue dissection is performed to access internal sites, then complete access is achieved, but operating room time and recovery time increase
Solution Approach 1:
The device performs preliminary positioning of the shoulder and arm in the optimal surgical orientation before the procedure begins. This pre-positioning eliminates the need for time-consuming intraoperative adjustments and extensive tissue dissection, allowing the surgeon to immediately access the target area through minimal incisions.
Solution Approach 2:
The positioning device incorporates adjustable components that allow dynamic adaptation to different patient anatomies and procedural requirements. The adjustable shoulder pad and support structure can be modified during the procedure to maintain optimal positioning while minimizing the time required for setup and adjustment.
3Object-affected harmful factors
If minimal invasive techniques are used, then tissue trauma is reduced, but access to deep internal sites becomes difficult
Solution Approach 1:
The positioning device performs preliminary alignment of the shoulder, arm, and torso in the optimal orientation before minimal invasive procedures. By establishing this pre-positioning, the device creates clear access pathways to deep internal sites like the glenoid cavity, enabling endoscopic instruments to reach target areas easily through small incisions without requiring extensive tissue dissection.
Solution Approach 2:
The device utilizes three-dimensional positioning and spatial arrangement to solve the access problem. By positioning the patient's shoulder and arm in specific orientations in multiple dimensions, the device creates optimal access angles and pathways that allow endoscopic instruments to reach deep internal sites through minimal invasive approaches.
4Productivity
If patient positioning is not optimized, then procedures can be performed, but visualization and access to specific anatomical areas are compromised
Solution Approach 1:
The positioning device performs preliminary positioning of the patient's shoulder and arm in the optimal surgical orientation before the procedure begins. This pre-positioning ensures that when the surgeon begins the procedure, the anatomical structures are already aligned for optimal visualization and access, eliminating the need for time-consuming intraoperative repositioning and ensuring high-quality visualization throughout the procedure.
