Angled Anchor Holding Tool for Stable Lead Suturing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for securing electrode leads during implantation procedures, such as spinal cord stimulation, are challenging due to the need for minimally invasive surgery and the difficulty in stabilizing and suturing lead anchor devices in slippery environments.
Innovation Solution
An anchor holding tool with a holding tip and angled handle is used to securely engage and stabilize the lead anchor device, allowing for easy manipulation and suturing, featuring form-fit elements and an access opening for external tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a lead anchor device is used for axial fixation of the lead, then the lead is securely fastened to the spinal column, but the anchor device is difficult to manipulate and stabilize in slippery surgical environments
Solution Approach 1:
The holding tool serves as an intermediary device between the surgeon and the lead anchor device. It features a holding tip that engages with the anchor device and a handle that extends at an angle to provide leverage and control, enabling secure manipulation and stabilization of the anchor device during suturing operations in slippery surgical environments
2Object-affected harmful factors
If a small incision is used for minimally invasive surgery, then patient impact is reduced and recovery time is minimized, but access to and manipulation of the lead anchor device at the implantation site becomes challenging
Solution Approach 1:
The holding tool is designed with differentiated local qualities: the holding tip portion is configured to engage with the lead anchor device at the implantation site through the small incision, while the handle portion extends at an angle to provide ergonomic control outside the incision, enabling effective manipulation through minimal access
3Ease of manufacture
If common surgical tools such as surgical clips are used to hold the lead anchor device, then the tools are readily available, but secure holding and stabilization of the anchor device cannot be easily achieved
Solution Approach 1:
The holding tool is segmented into distinct functional portions: a holding tip specifically designed to engage with the lead anchor device, and a handle that provides leverage and control. This segmentation allows each portion to be optimized for its specific function, achieving secure holding and stabilization that common surgical clips cannot provide

AI summary
An anchor holding tool is used for holding, during an implantation procedure, a lead anchor device. The lead anchor device is used for anchoring a lead in a patient. The anchor holding tool includes a holding tip for engaging with the lead anchor device, and a handle connected to the holding tip. The holding tip generally extends along a longitudinal axis for receiving the lead anchor device along the longitudinal axis on the holding tip. The handle extends at an angle with respect to the longitudinal axis from the holding tip. The holding tip forms an inner face shaped to abut with an anchor body of the lead anchor device. The inner face includes a concave shape extending about the longitudinal axis for receiving the anchor body of the lead anchor device.
