Bone Drilling Driver With Real-Time Depth Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bone drilling techniques are inconvenient, time-consuming, and unreliable, often requiring trial and error and multiple radiographs to achieve the proper depth for implant insertion, leading to increased radiation exposure and procedural delays.
Innovation Solution
A medical drilling device with integrated rotational and axial drive controls, featuring a transducer for instantaneous depth measurement and a coupler system that allows for controlled and measurable penetration, eliminating the need for separate depth gauges and reducing radiation exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional depth gauges are used to measure bore depth, then depth measurement is possible, but the procedure becomes time-consuming and requires interruptions to drilling
Solution Approach 1:
The patent combines the depth measurement function with the drilling device itself. The electronic depth gauge is integrated into the drilling device, allowing continuous depth monitoring during drilling without requiring separate measurement steps or interruptions to the drilling procedure.
Solution Approach 2:
The patent replaces mechanical depth gauges with an electronic depth measurement system. The electronic depth gauge uses electronic sensors and display technology to provide real-time depth information, eliminating the need for manual mechanical measurement tools and procedures.
2Measurement precision
If multiple radiographs are taken to confirm proper implant insertion depth, then accurate depth verification is achieved, but radiation exposure increases
Solution Approach 1:
The patent replaces radiographic verification with electronic depth measurement. The electronic depth gauge provides real-time, accurate depth information during the procedure, eliminating the need for multiple radiographs to verify implant insertion depth and thereby reducing radiation exposure to surgeons, staff, and patients.
Solution Approach 2:
The electronic depth gauge provides self-verification of depth during the procedure. The system continuously monitors and displays depth information, allowing the surgeon to verify proper implant insertion depth without external verification methods like radiographs.
3Manufacturing precision
If trial and error methods are used to achieve proper drilling depth, then eventual accuracy is possible, but procedural efficiency decreases and hardware waste increases
Solution Approach 1:
The electronic depth gauge provides real-time feedback to the surgeon during drilling. The continuous depth display allows the surgeon to monitor drilling progress and stop at the precise desired depth without trial and error, improving both accuracy and efficiency.
Solution Approach 2:
The electronic depth gauge allows the surgeon to plan and execute the precise drilling depth from the beginning of the procedure. By having real-time depth information available, the surgeon can drill to the exact required depth on the first attempt, eliminating the need for trial and error and associated hardware waste.
