Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current lipomodelling instruments lack control over the orientation and position of adipose tissue deposition, leading to non-uniform distribution and post-operative complications such as resorption and necrotic tissue formation, due to their reliance on manual dexterity and fixed gear mechanisms.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual dexterity and sensitivity of the surgeon is used for tissue grafting, then the operation can be performed with simple instruments, but the distribution of adipose tissue is non-uniform leading to post-operative complications
Solution Approach 1:
The system incorporates a detection system that provides real-time feedback on the position and movement of the syringe, which is processed by a control system to automatically regulate plunger advancement. This closed-loop feedback mechanism ensures uniform deposition of adipose tissue by continuously monitoring and adjusting the injection parameters based on actual syringe position, thereby achieving precise tissue distribution without relying on surgeon manual dexterity.
Solution Approach 2:
The invention replaces the manual mechanical control system with an automated electromechanical system. The control system uses electronic signals to regulate the plunger advancement based on processed information from the detection system, substituting the surgeon's manual mechanical manipulation with an automated control mechanism that ensures precise and uniform tissue deposition.
2Adaptability or versatility
If fixed gear mechanisms are used for syringe control, then the structure is simple, but the volume of tissue injected cannot be continuously modulated leading to discretized injection volumes
Solution Approach 1:
The system employs dynamic control of the plunger advancement rate, allowing continuous modulation of the tissue injection volume. The control system adjusts the plunger speed and advancement amount in real-time based on processed position information, enabling flexible and continuous variation of injection parameters rather than fixed discrete volumes, thus achieving adaptable tissue deposition.
Solution Approach 2:
The invention replaces fixed gear mechanisms with an electronically controlled system that can dynamically adjust the plunger advancement. This substitution enables continuous modulation of injection volume by controlling the motor-driven plunger mechanism through electronic signals, providing versatile and adaptable tissue deposition capabilities.
3Measurement precision
If the syringe position and orientation are not controlled, then the instrument is easy to operate, but the deposition location and direction cannot be determined leading to non-uniform grafting
Solution Approach 1:
The detection system continuously monitors the syringe position and orientation, providing real-time feedback to the control system. This feedback enables precise determination of the deposition location and direction, allowing the system to automatically adjust injection parameters to achieve uniform grafting while maintaining ease of operation through automated control.
Solution Approach 2:
The system performs self-positioning and self-regulation by using the detection system to automatically determine syringe orientation and position, and the control system to autonomously adjust plunger advancement accordingly. This self-service capability eliminates the need for complex manual positioning operations while maintaining high measurement precision.

AI summary
The present invention discloses a device for the deposition of adipose tissue, comprising: a) a syringe (1) for grafting the tissue, b) a system for controlling the advance of the plunger (5) of the syringe (1), which receives information about the movement of the syringe (1) in the direction of withdrawal from an external system for detecting the movement of the syringe, and c) an external system for detecting the movement of the syringe, characterized in that the control system determines the advance of the plunger (5) of the syringe (1) on the basis of the movement of the syringe (1) in the direction of withdrawal and on the basis of the quantity of adipose tissue per unit of length of deposition. The advantages deriving from the use of this device in lipomodelling (or fat grafting) are in an automatic control of deposition of the adipose tissue and a correct uniformity of the graft.
