Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fast-action clamping devices for surgical applications lack the ability to securely and easily adjust clamping positions without unintentional loosening, limiting the flexibility and efficiency of surgical procedures.
Innovation Solution
A fast-action clamping device featuring a handle with rod recesses, a tension rod, and a link lever with a locking mechanism, allowing for secure clamping and adjustable positions through a pivot mechanism and a pawl system, enabling one-handed operation and preventing unintentional transitions between clamping positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a fast-action clamping device is used for rapid adjustment, then the speed of position change is improved, but the risk of unintentional loosening increases
Solution Approach 1:
The locking mechanism with pawl and arch section is designed to automatically engage and prevent unintentional loosening before it can occur. The blocking section preemptively counteracts any forces that might cause the link lever to return to the non-clamping position, thus resolving the contradiction between fast action and reliability.
2Reliability
If a locking mechanism is added to prevent unintentional loosening, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The locking mechanism is designed as a self-acting system where the pawl automatically engages with the arch section's teeth when the link lever is in the clamping position. The spring-loaded pawl self-adjusts to maintain engagement without requiring external control systems, thus improving reliability while minimizing added complexity.
3Ease of operation
If the clamping mechanism is designed for one-handed operation, then the ease of operation is improved, but the clamping force may be reduced
Solution Approach 1:
The link lever is designed with a curved arch section that provides mechanical advantage throughout its pivoting range. The curved geometry allows the user to apply force at an optimal angle, maximizing the clamping force generated from one-handed operation. The arc-shaped locking section also distributes forces more effectively across the engagement points.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device provides secure clamping with adjustable positions, preventing unintentional loosening and allowing for efficient one-handed operation, enhancing surgical procedure flexibility and reducing the need for tools.
Implementation Method 1
a tension rod (33), which is arranged to exert tension on the first rod recess (13) and/or on the second rod recess (17). This tension causes the clamping via the fast-action clamping device (1), as the latter is transferred from the non-clamping position into the clamping position
Implementation Method 2
a link lever (5) which is pivotally connected to the handle (3) using a hinge mechanism (25)
Implementation Method 3
The locking section (45) is arranged to interact together with a blocking section, in particular a pawl (47), in order to disable or prevent automatic transition of the link lever (5) from a position of the link lever (5) set by a user towards the non-clamping position

AI summary
The present disclosure relates to a fast-action clamping device includes a handle including rod recesses, a tension rod and a link lever that can apply a fast-action clamping to a portion of an object that can have a rod-shaped from. The device is formed in that sections of an object may be received in the rod recesses and clamped in a clamping position without a clamping position of the link lever, set by a user, being able to pass into a non-clamping position. It also relates to a surgical device which includes such a fast-action clamping device.
