Bone Plate Holder With Adjustable Arms And Stabilizing Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manipulating and anchoring laminoplasty plates in spinal and orthopedic procedures is challenging due to their small size and difficulty in handling.
Innovation Solution
A bone plate system with a variety of lengths and an instrument featuring adjustable arms with connection tips and stabilizing members to securely hold and position the plates relative to bone segments, allowing for precise placement and anchoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a bone plate is used to fix bone segments, then the bone segments are stabilized, but the bone plate becomes difficult to handle and manipulate
Solution Approach 1:
The patent introduces a bone plate holder as an intermediary tool that grasps and manipulates the bone plate during surgical procedures. The holder includes connection tips that engage with the bone plate's side walls, allowing the surgeon to control and position the small bone plate without directly handling it, thus resolving the difficulty of manipulation while maintaining the plate's stabilizing function
2Manufacturing precision
If the bone plate is made small for precise fitting, then the plate can be positioned accurately, but it becomes harder to manipulate and anchor
Solution Approach 1:
The bone plate holder is divided into multiple functional components: a shaft for insertion, connection tips for engaging the plate, and stabilizing members for securing the plate against bone. This segmentation allows each component to perform its specific function, enabling precise positioning and anchoring of small plates without requiring direct manual manipulation
3Stability of the object's composition
If the bone plate is held securely during anchoring, then placement stability is improved, but the instrument complexity increases
Solution Approach 1:
The patent combines multiple functions into a single integrated bone plate holder instrument. The holder merges the functions of grasping (via connection tips), stabilizing (via stabilizing members), and positioning (via adjustable arms) into one device. This consolidation achieves secure plate placement stability without requiring multiple separate tools, thus managing device complexity while improving operational efficiency

AI summary
An instrument for holding a bone plate may include a first arm, a second arm connected to and adjustable relative to the first arm, a first connection tip at the distal end of the first arm configured to connect to the first side wall of the bone plate, and a second connection tip at the distal end of the second arm configured to connect to the second side wall of the bone plate. A stabilizing member is connected to the first connection tip. The stabilizing member is distally spaced apart from the first connection tip to form an opening for receiving a portion of bone between the first connection tip and the stabilizing member.
