Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current endoscopic and arthroscopic drilling systems face challenges in producing off-axis sockets and holes in bone surfaces, requiring separate guiding devices and being prone to misalignment and infection risks due to reusable components, with limited flexibility in angular offset and rigidity during drilling.
Innovation Solution
A powered endoscopic drilling device with a distal portion that can be angularly offset by the surgeon, featuring a non-uniform flexural strength and a stabilizing wingnut to minimize deflection, allowing for adjustable angular offset and improved rigidity during hole drilling, and being designed for single-use to prevent infection risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a separate guiding device is used to produce off-axis sockets, then the desired location and angle can be achieved, but the device complexity increases and misalignment occurs due to guide shift
Solution Approach 1:
The patent combines the guiding function and drilling function into a single integrated endoscopic drilling device. The guide is no longer a separate component but is integrated into the drilling device itself, eliminating the need for separate guiding devices and reducing overall system complexity while maintaining alignment precision.
Solution Approach 2:
The endoscopic drilling device is designed to perform multiple functions: it serves as both the guiding device and the drilling device. The single device can determine the entry location, establish the drilling angle, and execute the drilling operation, making the system more versatile and easier to operate.
2Object-affected harmful factors
If reusable drilling devices are used, then cost is reduced, but infection risk increases due to cleaning and sterilization requirements
Solution Approach 1:
The patent describes a disposable endoscopic drilling device that is discarded after a single use. This eliminates the need for cleaning and sterilization between uses, completely removing infection risk from the drilling process and eliminating scheduling constraints related to sterilization cycles.
3Adaptability or versatility
If the distal portion is rigidly fixed, then drilling stability is improved, but angular offset flexibility is reduced
Solution Approach 1:
The patent incorporates a flexible distal portion that can be dynamically adjusted to different angular offsets while maintaining stability during the actual drilling operation. The flexibility allows pre-positioning at various angles, and once positioned, the device provides stable drilling performance.
Solution Approach 2:
The device allows changes in the angular offset parameter of the distal portion to adapt to different surgical requirements. The flexible section enables adjustment of the drilling angle while the overall device structure maintains sufficient rigidity for stable drilling once the desired angle is achieved.

AI summary
Described herein are specialized endoscopic drilling devices that may be readily powered by a conventional shaver handpiece and further may be utilized to secure a soft tissue graft to a boney surface. More particularly, the devices, systems and methods of the present invention enable the efficient and minimally invasive formation of off-axis sockets and/or tunnels in boney surfaces that may then serve as a site for graft placement by aperture and/or suspensory fixation means. As such, the present invention has particular applicability to the surgical repair and reconstruction of torn or ruptured tissues, such as ligaments and tendons, in the leg, knee and shoulder, for example.
