Multi-Implant Surgical Inserter for Precise Depth Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical devices require multiple changes during procedures to deploy multiple implants or tools, lacking efficient control over insertion depth.
Innovation Solution
A surgical device with a main handle, shaft, and inserter that allows for the deployment of multiple implants or tools using a single device, enabling controlled depth insertion through relative movements of the handle and shaft.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple surgical devices are used to deploy multiple implants or tools, then each implant can be deployed with a dedicated device, but the procedure time increases and device changes are required throughout the procedure
Solution Approach 1:
The surgical device is designed with a multi-functional capability to deploy multiple different types of implants or tools through a single device platform. The device includes a handle and shaft assembly that can accommodate various implant types (e.g., anchors, buttons, or other fixation devices) and deploy them sequentially without requiring device changes, thereby improving procedure efficiency and eliminating device change time.
Solution Approach 2:
The device is segmented into functional components including a handle, a shaft, and an inserter mechanism that can be independently controlled. The inserter can be advanced independently along the shaft to different positions, allowing selective deployment of multiple implants at different locations along the shaft without changing the main device.
2Productivity
If a single surgical device is used to deploy multiple implants, then device changes are eliminated, but control over insertion depth of each implant becomes challenging
Solution Approach 1:
The device incorporates feedback mechanisms through the inserter design that provides tactile and positional feedback to the surgeon during insertion. The inserter can be advanced along the shaft with controlled resistance and positional indication, allowing precise control over the insertion depth of each implant while maintaining the ability to deploy multiple implants sequentially.
Solution Approach 2:
The device features dynamic control mechanisms where the inserter can be advanced, held, and retracted at various positions along the shaft. This dynamic positioning capability allows the surgeon to control the insertion depth of each implant precisely by stopping the inserter at the desired location, then deploying the implant and repeating the process for subsequent implants at different depths.
3Length of moving object
If the inserter is moved distally to advance the implant, then the implant can be positioned deeper, but the complexity of controlling multiple implant positions increases
Solution Approach 1:
The control mechanism is segmented into independent controls for the inserter and the shaft. The inserter can be advanced independently along the shaft using a distal movement mechanism, while the shaft itself can be advanced or held independently. This segmentation allows simple, intuitive control of multiple implant positions without increasing overall device complexity, as each component has its own straightforward control mechanism.

AI summary
This disclosure details a surgical device configured to deliver multiple implants or tools, including corresponding techniques, assemblies, systems, and methods, for using the surgical device. A surgical device according to an exemplary aspect of the present disclosure includes, among other things, a main handle, a main shaft, an inserter partially within the main shaft, and an implant adjacent a distal end of the inserter. The surgical device is configured such that the implant is moveable from a retracted position within the main shaft to an intermediate position within the main shaft by distal movement of the inserter relative to the main handle. Further, the surgical device is configured such that the implant is moveable from the intermediate position to a deployed position distal of the main shaft by relative movement of the main shaft and the main handle.
