Proximal Hip Drill Clamp With Implant For Aligned Drilling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing orthopedic implant procedures often require separate steps for bone preparation and implant placement, leading to misalignments and excessive soft tissue damage due to the obscuration of the prepared bone by soft tissue.
Innovation Solution
A tool with two movable ends, one featuring a tip with spikes for gripping the bone and a receiver for retaining an implant, allowing for simultaneous bone preparation and implant placement, with adjustable clamping pressure and drill guides for precise hole drilling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate steps are used for bone preparation and implant placement, then each step can be performed independently, but misalignment between the prepared bone features and the implant occurs
Solution Approach 1:
The patent combines bone preparation and implant placement into a single integrated tool. The tool includes a bone preparation element and an implant placement element that work simultaneously, ensuring that the implant is precisely aligned with the prepared bone features while being placed in a single operation, thereby eliminating misalignment issues caused by separate steps
2Ease of operation
If soft tissue is attached to the bone using a fastener, then soft tissue can be secured to the bone, but the soft tissue obscures the prepared bone from the operator's view
Solution Approach 1:
The patent uses a specialized tool as an intermediary that can penetrate or displace the soft tissue to access and work on the underlying bone. The tool includes features that allow it to navigate through soft tissue while maintaining precise control and visibility for the operator, enabling both soft tissue attachment and bone preparation without the obscuration problem
3Productivity
If a tool consolidates bone preparation and implant placement, then misalignments and operation time are reduced, but the tool complexity increases
Solution Approach 1:
The patent designs a universal tool that performs multiple functions: bone preparation, implant placement, and soft tissue attachment. By integrating these functions into a single multi-functional device, the tool reduces the need for multiple separate instruments, thereby decreasing overall procedural complexity despite the increased capabilities of the individual tool
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables precise alignment and secure attachment of implants by consolidating bone preparation and implant placement, reducing misalignments and soft tissue damage while facilitating efficient drilling.
Implementation Method 1
The bars may be biased with respect to one another such that the ends are biased apart from one another. The bias may be provided by one or more resilient springs disposed between the bars.
Implementation Method 2
The mechanism may include a threaded rod extending between the bars. The mechanism may further include a knob on the threaded rod that has a variable position and limits the possible range of positions of the bars relative to one another to an extent that varies along with the position of the knob.
Implementation Method 3
The tip may include spikes or other features for providing grip or traction between the tip and the surface of the bone.

AI summary
A tool for implanting an orthopedic implant upon a bone includes a body defining an implant socket for releasably retaining an implant and a drill guide opening into the implant socket. The body is an insert receivable in an insert socket of a movable end of the tool. The tool also includes a tip toward which the implant socket faces and opposedly movable relative to the body. The tool is usable in a process that includes clamping a bone between the tip and the implant while the implant is retained in the implant socket. While the bone is clamped, a drill is driven through the drill guide to produce a hole in the bone.
