Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional implanting devices cause membrane dislocation and deformation during withdrawal from biological tissue due to contact, prolonging surgical time and increasing the risk of surgery failure.
Innovation Solution
An implanting device with a sleeve, membrane storage element, injection element, and bubble generating element, where the injection element captures and stores the membrane, and the bubble generating element outputs gas to push the membrane into position within the tissue, minimizing contact and dislocation risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the implanting device contacts the membrane during implantation, then the membrane can be captured and implanted, but the membrane moves along with the device during withdrawal causing dislocation and deformation
Solution Approach 1:
The implanting device is divided into separate functional modules: a capturing element with first holes for initial membrane capture, and a bubble generating element for subsequent positioning. This segmentation allows the capturing element to be withdrawn without disturbing the membrane, while the bubble generating element independently adjusts membrane position through gas injection.
Solution Approach 2:
Gas bubbles serve as an intermediary medium between the implanting device and the membrane. Instead of direct mechanical contact for positioning, the bubbles are injected through the first holes to push and flatten the membrane into the correct position, eliminating the need for continuous mechanical contact during withdrawal.
2Reliability
If a separate bubble generating device is used after implantation, then bubbles can be filled to position the membrane, but this requires multiple devices and increases surgical complexity
Solution Approach 1:
The capturing element and bubble generating element are merged into a single integrated implanting device. The capturing element includes first holes that serve dual purposes: allowing gas passage during the capturing phase and serving as injection channels for bubble generation during the positioning phase. This eliminates the need for a separate bubble generating device.
Solution Approach 2:
The first holes in the capturing element are designed with multi-functionality: they initially allow membrane passage during capture, then serve as gas injection channels for bubble generation, and finally act as positioning channels for membrane adjustment. This universal design consolidates multiple functions into a single structural feature.
3Ease of operation
If the membrane is left in contact with the implanting device during withdrawal, then the membrane can be easily manipulated, but the membrane dislocates and deforms due to contact
Solution Approach 1:
The membrane is preliminarily captured by the capturing element before implantation, allowing easy manipulation during the implantation process. After successful capture and positioning, the membrane is released and held in place by gas bubbles, enabling clean withdrawal of the device without disturbing the membrane position.
Solution Approach 2:
Gas pressure is used to replace mechanical contact for membrane manipulation. After initial capture, gas bubbles are injected to push and flatten the membrane into the desired position, then the gas maintains the membrane in place during device withdrawal, eliminating the need for continuous mechanical contact.

Function Achieved in This Case
The device effectively positions and secures the membrane within the biological tissue, reducing surgical time and improving success rates by minimizing membrane dislocation and deformation during implantation and withdrawal.
Implementation Method 1
The bubble generating element is connected to the connecting end, and provides a gas that is then outputted via the first hole

AI summary
An implanting device is used for implanting a membrane in a biological tissue. The implanting device includes a sleeve, a membrane storage element, an injection element and a bubble generating element. The membrane storage element is fixed at the sleeve. The injection element is inserted in the sleeve and the membrane storage element, and includes a capturing end and connecting end. The capturing end is for capturing the membrane and has a hole. The bubble generating element is connected to the connecting end, and is for providing a gas that is then outputted via the hole. By the rotation of the injection element, the capturing end extends straight out of the membrane storage element or retracts straight into the membrane storage element.
