Impact-Absorbing Medical Tool Holder for Misaligned Surgical Strikes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical tools and holders are prone to deformation or damage due to abnormal impacts during surgical procedures, particularly in artificial joint surgeries like hip joint surgery, where misalignment of the striking force can cause damage to the impactor, holder, and even injury to medical personnel or robots.
Innovation Solution
An impact-reducing device for medical tools featuring an impact-absorbing member and a separation-preventing mechanism, comprising an elastic member and flanges to absorb and buffer impacts, preventing separation and damage to the tool and holder.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the impactor is struck with a hammer during artificial hip joint surgery, then the artificial acetabulum-cup can be pressed and fitted, but if the striking direction is misaligned with the axial direction of the impactor, the holder and impactor may be broken or damaged
Solution Approach 1:
The patent introduces an elastic member (such as a spring or rubber element) positioned between the impactor and the holder. This cushioning element is pre-installed to absorb abnormal impact forces before they reach the holder and impactor, thereby preventing breakage while allowing normal surgical operations to proceed efficiently
Solution Approach 2:
The elastic member serves as an intermediary element between the impactor and the holder. When misaligned striking occurs, this intermediary component absorbs and dissipates the abnormal forces, protecting both the impactor and holder from damage while not interfering with the normal transmission of controlled impact forces during proper surgical use
2Ease of operation
If the hammer misses the impactor, then the impact force is obliquely applied to the artificial acetabulum-cup, but this causes injury or damage to the medical personnel or robot holding the holder
Solution Approach 1:
The elastic member is pre-positioned in the impact path to cushion and absorb oblique or missed impact forces before they can be transmitted to the holder and subsequently to the medical personnel or robot, thereby preventing injury while maintaining operational flexibility
Solution Approach 2:
The elastic member converts the harmful oblique impact forces (when the hammer misses) into beneficial absorbed energy, dissipating the harmful forces through deformation and friction while preventing damage to the operator, thus turning a potentially harmful situation into a safe one

AI summary
The disclosure relates to an impact-reducing device for medical tools and a medical holder having the same, and more specifically to an impact-reducing device for medical tools, which absorbs and buffers an abnormal impact applied to the medical tools to prevent a medical holder, the medical tool or peripheral devices from being deformed or damaged, and the medical holder having the same. The impact-reducing device for medical tools, includes: an impact-reducing device main body formed with a tool insertion hole in which a tool shaft of the medical tool is inserted; an impact absorbing member placed in the impact-reducing device main body and absorbing impact applied to the medical tool; and a separation preventing member installed in the impact-reducing device main body to prevent separation of the impact absorbing member.
