Minimally Invasive Bone Drilling System for Targeted Treatment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for delivering medical treatments to bone tissue are invasive and require excessive treatment amounts, leading to damage to other body parts and increased costs, while drilling into bone is difficult and often results in fracturing.
Innovation Solution
A minimally invasive drilling system comprising a miniature shaft, hypodermic guide tube, cortex adapter, and stylet, allowing for precise, small-diameter hole drilling into bone for targeted treatment delivery, with a hypodermic needle guide tube and ductile bit design to minimize bone damage and facilitate direct treatment application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional drilling methods are used to access bone tissue, then treatment delivery is achieved, but bone fracturing occurs and invasion is significant
Solution Approach 1:
The patent changes the critical parameter of drill bit diameter from traditional large sizes to a small diameter of 0.002 to 0.006 inches. This parameter change enables minimally invasive bone access while maintaining reliable treatment delivery capability through the small drill bit and associated delivery system components.
Solution Approach 2:
The patent segments the treatment delivery system into multiple specialized components: a small drill bit for creating minimal bone access, a guide tube for positioning, a stylet for stabilizing the delivery pathway, and a treatment delivery catheter. This segmentation allows each component to be optimized for its specific function while collectively achieving minimally invasive treatment delivery.
2Object-affected harmful factors
If traditional treatment delivery methods are used, then treatment reaches the target tissue, but excessive treatment amounts are applied causing damage to other body parts
Solution Approach 1:
The patent implements local quality by creating a highly localized treatment delivery pathway through the small drill bit and guide tube assembly. This localized approach confines the treatment delivery to the specific target area within the bone, preventing excessive treatment amounts from reaching and damaging other body parts while ensuring adequate treatment of the target tissue.
3Ease of operation
If large diameter passages are drilled in bone, then treatment delivery is achieved, but the invasion level increases and bone fracturing occurs
Solution Approach 1:
The patent fundamentally changes the drill bit diameter parameter to a small range of 0.002 to 0.006 inches, making the drilling operation minimally invasive. This parameter change reduces bone fracturing risk while maintaining drilling feasibility through the small size and precision of the drill bit and guide tube assembly.

AI summary
A minimally invasive method for drilling into bone and for providing for delivery of medical treatment is provided. The method includes use of a drilling system includes a miniature shaft, a bit, a guide tube encapsulating the shaft during drilling and a cortex adapter thereafter to prevent closure of the drilled hole, a stylet to prevent blockage of the resulting passage, and introduction for treatment following removal of the stylet. As a result, a hole, targeted towards a cancerous lesion within the bone, is possible.
