Telescoping Surgical Support With Universal Positioning Joint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical tool support systems lack the flexibility and precision needed to universally position and securely lock surgical tools during procedures, limiting their adjustability and effectiveness in maintaining optimal tool positioning without manual intervention.
Innovation Solution
An adjustable surgical support system featuring a primary and secondary telescoping support with a positioning joint that includes universal pivotable and rotatable articulations, a ratchet mechanism, and a lock control, allowing for precise and secure positioning of surgical tools relative to the operating table, enabling easy repositioning and adjustment during surgeries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed surgical tool support system is used, then the tool positioning is stable, but the system lacks flexibility and cannot be easily repositioned during surgery
Solution Approach 1:
The patent applies dynamics by making the support system adjustable and reconfigurable during surgery. The horizontal bar can be repositioned along the vertical support, and the tool holder platform can be adjusted to different positions and orientations, transforming a static fixed system into a dynamic adaptable one that maintains stability through controlled adjustability
Solution Approach 2:
The support system is divided into separate adjustable components: a vertical support member, a horizontal bar with adjustable positioning, and a tool holder platform with independent adjustment capabilities. This segmentation allows each component to be independently positioned and locked, providing both flexibility for reconfiguration and stability when locked in place
2Productivity
If manual holding of surgical tools is used, then the system is simple, but the physician must exert continuous effort and cannot maintain precise positioning throughout the procedure
Solution Approach 1:
The support system is designed to maintain tool positioning autonomously without requiring continuous manual intervention. Once the surgical tools are positioned on the platform and the support components are adjusted and locked, the system self-maintains the positioning throughout the surgical procedure, freeing the physician from continuous manual holding effort
3Measurement precision
If a simple fixed support system is used, then the device complexity is low, but the positioning precision and adjustability are insufficient
Solution Approach 1:
The support system incorporates multiple functions within a unified structure: the vertical support provides both structural stability and height adjustment; the horizontal bar provides both positioning and tool mounting; the platform provides both tool holding and orientation adjustment. This multi-functionality achieves precise positioning capabilities without proportionally increasing overall system complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system provides enhanced flexibility and precision in supporting surgical tools, allowing for secure and adjustable positioning, reducing manual effort and improving surgical efficiency by allowing tools to be easily repositioned without moving the support system along the operating table rail.
Implementation Method 1
The primary telescoping support comprises a ratchet and a rack in telescoping association with respect to the ratchet, wherein the ratchet ratchets the rack to permit telescopic retraction of the rack and to prevent telescopic extension of the rack
Implementation Method 2
The first and second articulations may be ball-and-socket joints

AI summary
The surgical support system may include a primary telescoping support, secondary telescoping support supported from the primary telescoping support and configured for telescopically mounting a surgical tool thereto, such that telescoping of the primary support repositions the secondary telescoping support; and a positioning joint disposed between the primary and secondary telescoping supports for universally positioning and locking the secondary telescoping support with respecting to the primary telescoping support.
