Surgical Armrest with Adjustable Mounting for Microsurgery Ergonomics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surgeons experience strain and discomfort during surgical procedures due to prolonged static posture, particularly during microsurgery, which can affect their performance and accuracy, and existing surgical armrests do not adequately address these issues while maintaining a sterile surgical field.
Innovation Solution
A surgical armrest with adjustable and static configurations that allow for customizable support of a surgeon's forearms, wrists, or combinations thereof, featuring dorsal mounting brackets with elongated apertures enabling rotation and radial adjustment, integrated with a base station assembly for enhanced control and positioning without requiring assistance from non-scrubbed personnel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed static armrest is used, then the device complexity is reduced, but the adaptability to different surgeon positions and procedures is limited
Solution Approach 1:
The armrest incorporates adjustable components including height adjustment mechanism, angle adjustment mechanism, and position adjustment mechanism that enable the armrest to dynamically adapt to different surgeon positions and procedural requirements while maintaining reasonable device complexity through mechanical adjustment systems
2Ease of operation
If assistance from non-scrubbed personnel is required for positioning, then the ease of operation is improved, but the risk of contamination increases
Solution Approach 1:
The armrest is designed with multiple adjustment mechanisms that enable the surgeon to independently position and adjust the armrest to the desired configuration during the surgical procedure, eliminating the need for assistance from non-scrubbed personnel and thereby preventing contamination of the sterile surgical field
3Productivity
If prolonged static posture is maintained, then the productivity is improved, but the surgeon fatigue increases
Solution Approach 1:
The adjustable armrest allows the surgeon to dynamically modify the support position, height, and angle during the surgical procedure, enabling maintenance of ergonomic posture over extended periods and reducing fatigue-related performance degradation while sustaining surgical productivity

AI summary
A surgical armrest is disclosed. In one embodiment, the surgical armrest includes a body having two dorsal mounting brackets attached thereto. Each of the dorsal mounting brackets have an elongated aperture with an armrest member attached thereto. Each of the elongated apertures defines two ranges of rotation substantially parallel to a horizontal axis of the body. Each of the armrest members are configured to support a surgeon's elbow, forearm, wrist, or a combination thereof, during a surgical procedure, such as an operative microsurgery procedure on the skull and brain, for example.
