Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional stereotactic frames used in epilepsy surgery are cumbersome, require multiple coordinate adjustments, and break sterility, while robotic devices offer safety and reliability at a higher cost.
Innovation Solution
A stereotactic device with a u-shaped body and a moveable guide that allows precise implantation of medical instruments into multiple target areas within the patient's brain using a single coordinate system, maintaining sterility and reducing the need for repeated adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional stereotactic frames are used for implantation, then implantation can be performed, but the device is cumbersome and requires multiple coordinate adjustments which break sterility
Solution Approach 1:
The stereotactic device is divided into separate functional components: a stereotactic frame for positioning, a guide assembly for instrument delivery, and an instrument holder. This segmentation allows the guide to be moved and repositioned independently without requiring frame removal or coordinate system changes, thereby maintaining sterility while reducing operational complexity.
Solution Approach 2:
The guide assembly is designed to be moveable along the stereotactic frame, allowing dynamic repositioning to access different target areas within the patient's head. The guide can be locked at various positions and unlocked for repositioning, enabling multiple implantations without breaking sterility. This dynamic capability eliminates the need for multiple coordinate adjustments required by traditional static frames.
2Adaptability or versatility
If traditional stereotactic frames require multiple coordinate adjustments, then different target areas can be accessed, but sterility is broken requiring re-prepping
Solution Approach 1:
The guide assembly serves multiple functions: it can be positioned to access different target areas within the patient's head, hold various medical instruments, and maintain a single coordinate system throughout the procedure. This multi-functionality allows the same guide structure to accommodate diverse implantation needs without requiring frame removal or coordinate system changes, thereby preserving sterility.
3Reliability
If robotic stereotactic devices are used, then safety and reliability are improved, but cost increases significantly
Solution Approach 1:
The stereotactic device enables the surgical team to perform multiple implantations independently without requiring expensive robotic automation. The guide assembly can be manually repositioned and locked at different locations along the stereotactic frame, allowing the surgical team to access multiple target areas and perform multiple implantations using a single coordinate system, thereby eliminating the need for costly robotic systems while maintaining safety and reliability.

AI summary
The present disclosure relates generally to precise stereotactic implantation of an instrument (e.g., a recording electrode, a stimulating electrode, a biopsy instrument, a catheter, a delivery device, and the like) into a target area in a patient's brain. As such, one aspect of the present disclosure can relate to a stereotactic device that can be used to accomplish the precise implantation of the instrument. The stereotactic device can include a body to secure the stereotactic device to the patient's head. In some instances, the body can have a u-shape. The stereotactic device can also include a guide attached between sides of the body to move an instrument holder into place above a target area. The guide can be locked in position to lock the instrument holder in the place to facilitate injection of the instrument into the target area.
