Surgical Tool Holder with Fixed-Angle Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The precise positioning and stabilization of inflatable bone tamps during surgical procedures for bone fractures are challenging due to limited anatomical support, often requiring additional assistance to maintain proper alignment and delivery of bone void filler material.
Innovation Solution
A surgical tool holder device with a base that stabilizes the cannula at a fixed angle, using a collet or snap-fit mechanism to prevent movement and ensure accurate placement and trajectory, allowing single-handed administration of bone filler material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the inflatable bone tamp is used without a holder device, then the surgical procedure can be performed with simpler equipment, but precise positioning and stabilization of the tool is difficult due to limited anatomical support
Solution Approach 1:
The holder device serves as an intermediary between the surgeon's hand and the inflatable bone tamp. It provides a stable platform with fixed-angle guides that mediate the positioning of the tool, ensuring precise and consistent placement while reducing the need for complex manual stabilization techniques
Solution Approach 2:
The holder device is pre-configured with retaining portions at specific fixed angles (e.g., 45 degrees) relative to the longitudinal axis. This preliminary setup of geometric constraints ensures that the inflatable bone tamp is positioned correctly before the surgical procedure begins, eliminating the need for complex real-time adjustments
2Reliability
If additional assistance is used to hold the inflatable bone tamp, then positioning accuracy can be improved, but the surgical procedure becomes more complex and time-consuming
Solution Approach 1:
The holder device is designed to be self-stabilizing through its geometric structure. The retaining portion with fixed-angle guides and the locking mechanism allow the device to maintain its own position and the tool's position without requiring additional personnel to manually hold or stabilize components during the procedure
Solution Approach 2:
The holder device is divided into distinct functional segments: a base for stabilization, a retaining portion for angle control, and a locking mechanism for fixation. This segmentation allows each component to perform its specific function independently, improving overall reliability while maintaining ease of operation through modular design
3Ease of operation
If the surgical tool is held manually without a locking mechanism, then the device structure can be simpler, but translation and misalignment of the tool can occur
Solution Approach 1:
The locking mechanism provides dynamic control over the inflatable bone tamp's position. It allows the tool to be initially inserted with ease, then locked at the precise position and angle required, and can be released if adjustment is needed. This dynamic capability maintains both ease of operation and alignment precision throughout the procedure

AI summary
A device for holding a surgical tool comprising a base extending along a longitudinal axis between a proximal end and a distal end. The distal end is configured for engagement with a body of a patient to stabilize the device. A retaining portion is disposed at a fixed angle relative to the longitudinal axis and includes an inner surface defining a passageway configured to receive the surgical tool and hold the surgical tool at the fixed angle. A locking element is configured to apply a clamping force to the retaining element such that translation of the surgical tool is prevented in a direction transverse to the longitudinal axis.
