Resorbable Suture Anchor Self-Tapping Bone Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional suture anchor systems require pre-drilling or tapping of bone, making orthopedic surgical procedures complex and time-consuming for securing soft tissues, tendons, and ligaments to bone.
Innovation Solution
A resorbable suture anchor system with a cannulated tip and engagement surfaces that can be implanted without pre-drilling, using a driver to secure the anchor within the bone and allowing for resorption at a desired rate, along with a method for implanting the anchor that includes piercing the bone with the tip and expanding wings to prevent migration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pre-drilling and tapping of bone is performed to secure suture anchors, then the anchor can be firmly attached to bone, but the surgical procedure becomes complex and time-consuming
Solution Approach 1:
The patent extracts and eliminates the pre-drilling and tapping steps from the surgical procedure. The suture anchor is designed with a self-tapping feature that allows direct insertion into bone without requiring separate drilling and threading operations, thereby simplifying the procedure while maintaining secure attachment.
Solution Approach 2:
The patent combines the drilling, tapping, and anchor insertion operations into a single integrated action. The suture anchor incorporates self-tapping threads and a design that allows it to create its own insertion path and secure attachment simultaneously, reducing multiple steps to one unified surgical action.
2Reliability
If conventional suture anchors are used requiring pre-drilling, then secure soft tissue attachment can be achieved, but surgical time is increased
Solution Approach 1:
The suture anchor is pre-configured with self-tapping threads and an optimized geometry that enables direct insertion. The threads are预先 formed on the anchor body, eliminating the need for separate tapping operations during surgery, thus reducing surgical time while ensuring secure soft tissue attachment.
Solution Approach 2:
The suture anchor performs its own installation function by creating the insertion path and securing itself into the bone through self-tapping action. This self-service capability eliminates the need for separate drilling and tapping tools, significantly reducing surgical procedure time while maintaining attachment security.
3Object-generated harmful factors
If resorbable material is used for the suture anchor, then controlled resorption occurs reducing complications, but the anchor may have reduced initial strength
Solution Approach 1:
The suture anchor utilizes composite material construction, combining resorbable polymers with optimized structural design. The composite approach allows the anchor to achieve sufficient initial strength for secure soft tissue attachment while maintaining the ability to resorb over time, thereby reducing long-term complications without sacrificing initial mechanical performance.
Solution Approach 2:
The patent employs parameter optimization in the resorbable material selection and anchor geometry design. By carefully controlling material composition, density, and structural parameters, the anchor achieves the desired balance between initial strength for secure attachment and controlled resorption rate to minimize complications.

AI summary
A resorbable suture anchor operable to hold a suture within a bone. The suture anchor has a cannulated tip that receives a driver during implantation of the anchor, the driver extending from the tip when the anchor is seated on the driver. The anchor further has at least one engagement surface to prevent migration of the anchor from the implantation site. The anchor is made of a resorbable material to permit resorbtion of the anchor within a patient at a desired rate.
