Bone Treatment System Cured Material Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bone treatment methods using bioabsorbable balloons for bone filling materials are inefficient due to the lengthy treatment period and difficulty in placing cured bone filling material inside the bone, as hydrophilic materials can disintegrate and disperse before curing, making osteosynthesis challenging.
Innovation Solution
A bone treatment system comprising a shaft with a lumen, a placement device with a balloon for filling bone filling material, and a deployment operation device that inserts into the lumen to break the balloon after filling, allowing the cured bone filling material to be easily exposed and placed inside the bone, minimizing exposure to body fluids and ensuring reliable curing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the balloon is filled with bone filling material before placement, then the bone filling material can be delivered to the treatment site, but the treatment period is considerably lengthened
Solution Approach 1:
The system separates the bone filling material delivery function from the balloon deployment function. The balloon is deployed first to create a cavity, then the cured bone filling material is injected through the catheter into the pre-formed cavity, eliminating the waiting time for material curing while maintaining effective delivery.
2Ease of operation
If the bone filling material is exposed from the balloon in a liquid or paste state, then it can be placed inside the bone, but the material is easily disintegrated and dispersed in the body
Solution Approach 1:
The bone filling material is cured before being placed into the bone cavity. The system enables injection of the cured material through the catheter into the balloon-formed cavity, ensuring the material maintains its structural integrity and does not disintegrate or disperse in the body, while still achieving easy placement through the catheter delivery system.
3Quantity of substance
If a larger and cured bone filling material is placed inside the bone, then osteosynthesis is promoted, but it is difficult to expose such material from the balloon
Solution Approach 1:
The system divides the process into two independent steps: first, deploy the balloon to create a cavity of the desired size and shape; second, inject the cured bone filling material through the catheter into the pre-formed cavity. This segmentation allows large volumes of cured material to be placed without the difficulty of exposing them from the balloon, as the material is delivered through the catheter into the pre-prepared space.
4Ease of operation
If the bone filling material comes into contact with body fluid when injected, then it can be placed inside the bone, but the material is poorly cured or disintegrated
Solution Approach 1:
The balloon cavity acts as an intermediary space that isolates the bone filling material from direct contact with body fluids during the injection and curing process. The catheter delivers the cured material into this protected cavity, preventing premature contact with body fluids that would cause poor curing or disintegration, while still enabling easy injection through the catheter system.

AI summary
[Problem] To easily and accurately place a bone filling material in a cured state on a bone treatment target. [Means for Resolution] A bone treatment system 10 includes a placement device 14 and a deployment operation device 16. The placement device 14 includes a shaft 30 having a flow path 38 which enables a bone filling material to be placed on a space 108 of a radius 100 to flow therethrough, and a filling balloon 32 to be filled with the bone filling material via the flow path 38 disposed in a distal end portion of the shaft 30. The deployment operation device 16 can be inserted into the flow path 38, and exposes the bone filling material by breaking the filling balloon 32 after being filled with the bone filling material.
