Treatment Tool Gripper Dynamics for Uniform Pressure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional treatment tools experience uneven gripping pressure distribution when gripping thin and soft versus thick and hard living tissues, leading to inconsistent treatment outcomes.
Innovation Solution
The treatment tool incorporates a second gripper with elongated holes for the driving and pivoting shafts, allowing the gripper to pivot and move in a way that maintains parallel gripping surfaces, distributing force uniformly across the tissue regardless of its thickness or hardness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If the second gripper is further pivoted in a direction to approach the first gripper, then the gripping force increases, but the first gripper warps and gripping pressure distribution becomes uneven
Solution Approach 1:
The second gripper is designed to pivot about a pivoting shaft, transforming the gripping mechanism from a static rigid structure to a dynamic articulated system. This allows the second gripper to rotate and adjust its position, enabling uniform force distribution across the treatment target while maintaining effective gripping force. The pivoting motion accommodates variations in tissue thickness and hardness without causing warping or uneven pressure distribution.
2Adaptability or versatility
If the second gripper pivots about the pivoting shaft, then the gripping pressure distribution becomes uneven for thin and soft tissues, but the design needs to work for both thin and thick tissues
Solution Approach 1:
The articulated design with pivoting shaft enables the gripper to dynamically adapt its configuration based on the treatment target characteristics. For thin and soft tissues, the pivoting action allows the second gripper to approach the first gripper without excessive force concentration. For thick and hard tissues, the same pivoting mechanism provides the necessary mechanical advantage and force multiplication, achieving uniform pressure distribution across different tissue types.
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
This design ensures consistent gripping pressure distribution, preventing excessive pressure on either side of the tissue, thereby enhancing treatment efficacy and reducing variations in gripping force.
Implementation Method 1
the treatment tool treats the treatment target by applying ultrasound vibration to the treatment target from a treatment portion

AI summary
A treatment tool includes: a first gripper; a second gripper configured to pivot relative to the first gripper to grip a living tissue between the second gripper and the first gripper; a support being provided with a pivoting shaft configured to engage with the second gripper and serve as a pivoting center of the second gripper; and a driver provided with a driving shaft configured to engage with the second gripper, the driver being configured to move forward and backward to pivot the second gripper.
