Anchor Drill Device with Converging Lumens for Minimally Invasive Surgery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In minimally invasive endoscopic surgery, it is challenging to accurately locate and align pilot holes after drilling due to tool and tissue shifting, making it difficult to properly place hardware.
Innovation Solution
The development of an anchor drill device with multiple lumens that converge at a distal guide end, allowing for the extension of a drill tip and suture anchor, along with a suture anchor device that supports knotless locking and re-tensioning suture engagements, enables precise placement and alignment of hardware without removing the drill from the site.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If drills are removed after drilling pilot holes, then the drilling operation is complete, but it becomes difficult to locate and align hardware with the pilot holes due to tissue shifting
Solution Approach 1:
The patent combines the drill device and hardware placement device into a single integrated anchor drill device. The drill stem and anchor introducer are positioned in separate lumens that converge at the distal guide end, allowing both drilling and anchor insertion to occur through the same guide structure, thereby maintaining alignment precision while enabling complete operation
Solution Approach 2:
The guide end structure serves as an intermediary element that maintains the spatial relationship between the drill tip and anchor introducer. By providing a fixed geometric relationship at the distal end, it ensures that the anchor is precisely positioned over the pilot hole without requiring removal of the drilling instrument
2Adaptability or versatility
If multiple instruments are used for drilling and anchor insertion, then functional versatility is achieved, but tool shifting and alignment difficulty increase
Solution Approach 1:
Multiple instruments (drill stem and anchor introducer) are merged into a single integrated device structure with converging lumens. This allows multiple functions to be performed through one device while maintaining precise spatial relationships, reducing the complexity of managing multiple separate instruments
Solution Approach 2:
The anchor drill device is designed as a multi-functional instrument that can perform both drilling and anchor insertion operations. The handle with multiple lumens accommodates different instruments, making the device universal for various surgical steps without requiring separate specialized tools

AI summary
The present invention provides minimally invasive anchor drill devices for drilling pilot holes and inserting hardware into the pilot holes. The devices perform both functions without needing to be removed from a site of drilling, ensuring accurate placement of hardware while streamlining minimally invasive surgical procedures. The present invention also provides suture anchors capable of simultaneously supporting locking and re-tensioning suture configurations. The anchor drill devices and suture anchors can be used together for anchor-first procedures, suture-first procedures, and procedures linking several anchors together through combinations of locking and re-tensioning suture engagements.
