Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Custom-made stereotactic systems for medical device implantation are costly and time-consuming, with limited ability to accommodate subsequent targeting adjustments, such as when a large blood vessel is encountered in the planned implant trajectory.
Innovation Solution
A system comprising a frame member with adjustable legs and a spherical guide assembly that allows for pre-operative configuration and subsequent intra-operative adjustments, enabling precise positioning of medical devices in three-dimensional space, using a socket-and-ball mechanism for rotational alignment and adjustable leg lengths to accommodate various anatomical conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If custom-made stereotactic systems are used for medical device implantation, then precise device placement is achieved, but recurring costs increase and delivery time extends
Solution Approach 1:
The patent applies universality by designing a single reusable stereotactic platform that can accommodate multiple patients and various implantation scenarios. The platform includes adjustable components such as movable arms, rotatable joints, and repositionable guide holders that can be configured for different cranial entry points, trajectories, and target locations. This eliminates the need to create custom platforms for each patient while maintaining precise placement capability through programmable positioning and pre-configured settings.
Solution Approach 2:
The patent implements dynamics through multiple adjustable and movable components including arms that can be repositioned along tracks, joints that allow rotational movement, and guide holders that can be adjusted in position and orientation. These dynamic elements enable the platform to adapt to different surgical requirements and patient anatomies without requiring a custom-built system for each case, thereby reducing delivery time while preserving placement precision.

Solution Approach 2:
The patent implements a reusable platform design that can be sterilized and reused across multiple surgical procedures. The system is designed to be disassembled, sterilized, and reconfigured for different patients, thereby recovering the investment and eliminating recurring manufacturing costs associated with custom-made single-use platforms.
3Device complexity
If fixed stereotactic platforms are used, then initial setup is simplified, but ability to accommodate subsequent targeting adjustments is limited
Solution Approach 1:
The patent implements dynamics through multiple adjustable and movable components including arms that can be repositioned along tracks, joints that allow rotational movement, and guide holders that can be adjusted in position and orientation. These dynamic elements enable the platform to adapt to different surgical requirements and patient anatomies without requiring a custom-built system, thereby reducing delivery time while preserving placement precision.
Solution Approach 2:
The patent applies segmentation by dividing the platform into modular components such as separate arms, joints, and guide holders that can be independently adjusted and reconfigured. This modular design allows for flexible adaptation to different surgical scenarios while maintaining overall system simplicity and ease of setup.

AI summary
An implantation system for positioning and aligning an elongate medical device in three-dimensional space. The system may include: a frame member; and first, second, and third legs each having an adjustable length. Each of the first, second, and third legs includes: a first end having a socket segment, wherein the socket segments of each of the first, second, and third legs together define a socket; and a second end connected to the frame member. A spherical member is adapted to be received within the socket such that the spherical member may rotate about a center of rotation defined by the socket, the spherical member having an inner surface defining a bore passing through the spherical member.
