Surgical Drill With Internal Grasping Hook
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional surgical procedures require multiple entry points and instruments for drilling and grasping, leading to increased contamination, complexity, and prolonged recovery times due to the need to switch between drilling and grasping mechanisms, as well as the formation of multiple holes in the patient's body.
Innovation Solution
A surgical instrument with a drill bit featuring an internal grasping hook that allows for both drilling and grasping functions, reducing the need for multiple entry points and instruments by enabling the same tool to form passages and retrieve components through a single entry point.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple instruments (drill and grasping mechanism) are used for drilling and grasping operations, then the surgical procedure can be completed with conventional separate tools, but the procedure time increases, contamination risk increases, and multiple entry points are required
Solution Approach 1:
The patent combines a drill bit and a grasping mechanism into a single integrated surgical instrument. The drill bit features an internal grasping hook that can be deployed to grasp and retrieve objects through the drilled passage, eliminating the need to switch between separate drilling and grasping instruments. This merging reduces contamination risk by maintaining a single closed system and reduces procedure time by eliminating instrument exchanges and the need for secondary entry points.
Solution Approach 2:
The surgical instrument is designed with multi-functionality, allowing the same drill bit to perform both drilling operations and grasping/retrieval operations. The internal grasping hook can be deployed from the drill bit to grasp objects such as suture anchors or other components and pull them back through the drilled passage. This universal tool eliminates the need for multiple specialized instruments and multiple entry points, thereby reducing contamination risk and procedure time.
2Ease of operation
If multiple entry points are formed in the patient's body for drilling and grasping operations, then access to internal structures is achieved, but patient trauma increases and recovery time is prolonged
Solution Approach 1:
The patent combines drilling and grasping capabilities into a single instrument that accesses the surgical site through one entry point. The drill bit with its internal grasping hook allows the surgeon to drill through bone and then retrieve components through the same passage, eliminating the need for secondary entry points and reducing patient trauma.
Solution Approach 2:
The multi-functional drill bit serves both as a drilling tool and a retrieval tool through its internal grasping mechanism. This universality allows complete surgical access through a single entry point, avoiding the need for multiple incisions and thereby reducing patient trauma and recovery time while maintaining full access to internal structures.
3Reliability
If separate drilling and grasping instruments are used, then each instrument can be optimized for its specific function, but the surgical complexity and difficulty increase
Solution Approach 1:
The patent merges the drilling function and grasping function into a single integrated instrument. The drill bit includes an internal grasping hook that can be deployed to grasp objects. While this combines functions, the design maintains optimization for each function through specialized features (drill flutes for cutting, internal channel for debris removal, deployable hook for grasping) while reducing overall surgical complexity by eliminating instrument switches and multiple entry points.
Solution Approach 2:
The grasping hook is nested within the drill bit structure, allowing the grasping mechanism to be contained within the drilling instrument. The internal channel of the drill bit houses the grasping hook, which can be deployed when needed. This nesting arrangement allows both functions to coexist in a single instrument without significantly increasing external complexity, while maintaining optimized performance for both drilling and grasping operations.

AI summary
A surgical instrument is provided. The surgical instrument has a drill bit employable in drilling procedures wherein the drill bit has an internal grasping hook. As a result, the drill bit may not only drill into bone, but may also be used to grasp an object within or part of the body. The present surgical instrument reduces contamination and difficulty which may otherwise result from switching surgical instruments from a drill to a grasping mechanism or from the need to drill multiple holes into the patient's body.
