Glaucoma Drainage Tube With Positioning Wings for Stable Implant Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing glaucoma implant surgeries face challenges in accurately positioning and stably fixing the implant device within the eyeball, leading to potential damage and complications due to the need for precise placement and the difficulty in using small-sized implants.
Innovation Solution
The eye disease implant device features a tube with wings extending in a different direction from its longitudinal axis, which can be unfolded during insertion to stabilize the position, and a marker for precise placement, along with a curved shape to minimize corneal damage, and a support for secure fixation, allowing the tube and body to be combined or separated as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a small-sized glaucoma implant is used, then surgery becomes easier and side effects are reduced, but it becomes difficult to accurately position and stably fix the implant in the anterior chamber
Solution Approach 1:
The patent incorporates a positioning wing structure that is pre-formed on the implant device. This wing is designed to engage with the anterior chamber wall before the implant is fully deployed, providing preliminary positioning guidance that ensures accurate placement while maintaining the small size of the implant for easy surgery.
Solution Approach 2:
The positioning wing acts as an intermediary element between the small-sized implant and the anterior chamber wall. It provides a mechanical interface that enables accurate positioning and stable fixation without requiring the implant itself to be large or complex, thus resolving the contradiction between ease of surgery and positioning accuracy.
2Measurement precision
If direct insertion method is used, then the surgeon can place the implant at the correct position while watching, but damage may occur and considerable skill is required
Solution Approach 1:
The patent designs the implant with a positioning wing that engages with the anterior chamber wall to provide mechanical cushioning and protection. This structure prevents direct contact between the sharp insertion instrument and the eyeball tissue, reducing the risk of damage while maintaining placement accuracy through the wing's guidance function.
Solution Approach 2:
The positioning wing serves as an intermediary structure between the insertion instrument and the eyeball. It provides a safe interface that allows precise placement while preventing tissue damage, thereby reducing the skill requirement for the surgeon while maintaining accuracy.
3Productivity
If the tube is inserted deeply into the anterior chamber, then aqueous humor drainage is effective, but the tube may damage the corneal endothelium
Solution Approach 1:
The positioning wing is designed to engage with the anterior chamber wall before the tube is fully inserted. This preliminary engagement establishes a safe stopping point that prevents the tube from penetrating too deeply and damaging the corneal endothelium, while still allowing sufficient insertion depth for effective aqueous humor drainage.
Solution Approach 2:
The positioning wing provides mechanical feedback to the surgeon during insertion. When the wing engages with the anterior chamber wall, it creates a tactile sensation that signals the correct insertion depth has been reached, preventing over-insertion and corneal damage while ensuring adequate drainage efficiency.

AI summary
The present disclosure relates to an eye disease implant device, and an eye disease implant device according to an embodiment of the present disclosure includes a tube including a hollow portion through which aqueous humor is drained, wherein one or more wings extending in a direction different from a longitudinal direction of the tube are formed on a portion of an outer surface of the tube. Also, the eye disease implant device may further include a body including a receiving space into which an end of the tube is inserted. In this case, the end of the tube may be inserted into the receiving space to be coupled to the body, or detached from the receiving space to be separated from the body.
