Disposable Inflatable Joint Distraction Drape for Arthroscopy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current joint distraction devices for arthroscopic surgery are cumbersome, complex, and require pre-planning, making them difficult to use and expensive, while also not allowing for easy access to the joint space for visualization and correction of pathology.
Innovation Solution
A disposable joint distraction device comprising a drape with an inflatable member that can be inflated using a manual or electric pump, allowing for on-demand joint distraction without pre-planning, featuring a pouch for fluid collection and a pressure regulator to ensure safe inflation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional 3-point fixation pulley systems or hydraulic powered lifts are used for joint distraction, then joint distraction capability is achieved, but device complexity and ease of operation deteriorate due to cumbersome setup and specialized requirements
Solution Approach 1:
The patent employs an inflatable member (balloon) that can be inflated with fluid to distract the joint. This pneumatic/hydraulic approach replaces complex mechanical pulley systems and hydraulic lifts with a simple inflatable structure that can be easily deployed and adjusted during surgery.
Solution Approach 2:
The patent describes a disposable joint distraction device that includes a drape with an integrated inflatable member. The disposable nature eliminates the need for complex sterilization and setup procedures associated with reusable devices, while maintaining reliable joint distraction capability throughout the surgical procedure.
2Reliability
If traditional joint distraction devices are used, then joint distraction is achieved, but ease of operation and time efficiency worsen due to time-consuming setup in advance during patient positioning
Solution Approach 1:
The patent integrates the inflatable member directly into the surgical drape, combining two separate components (drape and distraction device) into a single integrated unit. This eliminates the need for separate setup procedures and allows the distraction device to be ready for use immediately when the drape is applied during surgery.
Solution Approach 2:
The inflatable member is pre-integrated into the drape structure during manufacturing, so that when the drape is applied to the patient, the distraction device is already in position and ready for inflation. This preliminary preparation eliminates time-consuming intraoperative setup procedures.
3Reliability
If traditional joint distraction devices are used, then joint distraction capability is maintained, but cost effectiveness deteriorates due to expensive equipment requirements
Solution Approach 1:
The patent describes a disposable joint distraction device that eliminates the need for expensive reusable equipment. The disposable nature reduces costs associated with sterilization, maintenance, and equipment replacement while providing reliable joint distraction capability for each surgical procedure.
Solution Approach 2:
The patent extracts the essential distraction function from complex mechanical systems and implements it through a simple inflatable member. This extraction of the core function eliminates the need for expensive associated equipment while maintaining effective joint distraction capability.
