Surgical Equipment Holder With Single-Lever Arm Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical equipment holders require two hands to position and lock surgical instruments, limiting single-handed adjustment and flexibility during minimally invasive procedures.
Innovation Solution
A surgical equipment holder design featuring a first arm, second arm, and end effector, with a lever that allows single-handed control to pivot and lock all components simultaneously, enabling one-handed positioning and adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate control knobs are used to lock each arm independently, then each arm can be securely locked in position, but two hands are required to adjust and lock the holder
Solution Approach 1:
The patent combines multiple independent locking mechanisms into a single integrated lever system. The lever simultaneously locks the first arm to the base, the second arm to the first arm, and the end effector to the second arm through a unified mechanical connection point, allowing all locking actions to be performed with one hand
2Ease of operation
If a single lever is used to control all locking points, then single-handed operation is enabled, but the mechanical complexity of the lever system increases
Solution Approach 1:
The patent introduces a lever as an intermediary mechanical element that translates a single rotational input motion into multiple simultaneous locking actions at different locations. The lever acts as a mediator that distributes the locking force to three separate connection points through its geometric configuration, simplifying the user interface while managing the underlying mechanical complexity

AI summary
A surgical equipment holder is disclosed. The surgical equipment holder includes a first arm pivotable relative to a base, a second arm pivotably coupled to the first arm and an end effector pivotable relative to the second arm. The surgical equipment holder also includes a lever configured to actuate between a locked and unlocked position by use of a single hand by an operator. The end effector of the surgical equipment holder is configured to support and finely adjust the position of any number of surgical accessories during surgical procedures.
