Telescopic Tissue Dilation System for Minimally Invasive Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tissue dilation methods, such as cutting or using multiple separate cannula dilators, are traumatic to patients, time-consuming, and pose risks of misplacement and contamination, while existing methods for bone fixation and spinal fusion procedures require extensive surgery and prolonged recovery times.
Innovation Solution
A telescopic tissue dilation system comprising two or more telescopically arranged dilation tubes that can be preassembled and locked, allowing for sequential unlocking and advancement to dilate tissue minimally invasively, providing access to target structures like bones, organs, and tissues with reduced trauma and improved ease of use.

Engineering Contradiction Analysis
1Object-affected harmful factors
If multiple separate cannula dilators are used for tissue dilation, then tissue trauma is reduced compared to cutting, but the procedure becomes time-consuming and complex due to serial steps
Solution Approach 1:
The patent combines multiple separate cannula dilators into a single integrated telescopic dilation system where multiple dilation tubes of different diameters are nested within each other. This allows all dilation steps to be performed in one continuous action rather than requiring serial insertion of separate dilators, thereby reducing procedure time while maintaining minimal tissue trauma.
Solution Approach 2:
The dilation tubes are arranged in a nested configuration where smaller diameter tubes are contained within larger diameter tubes. This nested structure enables sequential dilation by simply advancing the tubes in order of increasing diameter without requiring removal and reinsertion of separate dilators, thus eliminating time loss between dilation steps.
2Object-affected harmful factors
If multiple separate cannula dilators are used for tissue dilation, then tissue trauma is reduced, but the risk of misplacement and contamination increases
Solution Approach 1:
By combining multiple dilators into a single pre-assembled telescopic system, the patent eliminates the need to handle multiple separate dilator components. The entire dilation set remains contained within the outermost tube until needed, reducing opportunities for misplacement, dropping, or contamination that would occur when handling multiple separate dilators in sequence.
Solution Approach 2:
The dilation tubes are pre-assembled and pre-sterilized as a complete set before use. This preliminary preparation ensures proper organization and sterility, eliminating the risk of misplacement or contamination that would arise from assembling multiple separate dilators in the operating room.
3Strength
If traditional bone fixation procedures are performed with extensive surgery, then stable bone fusion is achieved, but patient recovery time is prolonged
Solution Approach 1:
The patent segments the surgical procedure into a minimally invasive percutaneous approach, separating the tissue access function from the bone fixation function. The telescopic dilation system creates a small access path that allows insertion of bone fixation devices without requiring large incisions and extensive soft tissue dissection, thereby maintaining bone fusion stability while dramatically reducing surgical trauma and recovery time.
Data Source
AI summary
Tissue dilation systems are disclosed. The present systems provide percutaneous access to one or more target structures located in a patient's body. The tissue dilation systems include two or more tissue dilation tubes telescopically arranged and moveable relative to each other. The tissue dilation tubes can be preassembled prior to use by utilizing a dilation tube retention assembly which can maintain the dilation tubes in a substantially fixed position and release the tubes therefrom in order to dilate a patient's tissue. Methods of producing the present systems and using the present systems in surgical procedures are also disclosed.
