Ultrasonic Gripper Interlocking Actuator Spacing Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ultrasonic treatment instruments face challenges in effectively adjusting the spacing distance between grippers to facilitate target grasping and efficient ultrasonic vibration transmission.
Innovation Solution
An ultrasonic treatment instrument featuring a vibration transmitting member with a first gripper and a movable second gripper, where an interlocking actuator increases the spacing distance between the grippers by rotating the first gripper in interlock with the movement of the second gripper, allowing for adjustable grip and efficient ultrasonic vibration transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the first gripper and second gripper are rotatably attached to the distal portion of the vibration transmitting member, then the grippers can be opened and closed to grasp and treat targets, but the spacing distance between the grippers cannot be effectively adjusted to facilitate target grasping
Solution Approach 1:
The patent applies the dynamics principle by making the first gripper rotatable relative to the second gripper through the interlocking actuator. This allows the spacing distance between the grippers to be dynamically adjusted during operation. The first gripper can rotate to increase spacing for easier target insertion, then rotate back to decrease spacing for secure grasping, providing adaptive control without requiring a completely complex mechanical structure.
2Reliability
If the vibration transmitting member transmits ultrasonic vibration to the grippers, then ultrasonic treatment can be performed, but the vibration transmission may be affected by the spacing distance between grippers
Solution Approach 1:
The patent resolves this contradiction by enabling dynamic adjustment of the first gripper's position relative to the second gripper. The interlocking actuator allows the first gripper to rotate and adjust the spacing distance, optimizing the transmission path for ultrasonic vibration while maintaining the ability to grasp targets effectively. This dynamic positioning ensures reliable vibration transmission regardless of the specific grasping configuration needed.
3Ease of operation
If the first gripper and second gripper are opened with respect to each other, then the treated target can be accessed, but the spacing distance increases making it difficult to maintain proper grip
Solution Approach 1:
The patent applies dynamics by allowing the first gripper to rotate independently of the second gripper through the interlocking actuator. When targets need to be accessed, the first gripper can rotate to increase spacing, providing easy access. When grasping is required, the first gripper can rotate back to decrease spacing, maintaining secure grip. This dynamic adjustment capability resolves the contradiction between target access and grip security.

AI summary
An ultrasonic treatment instrument includes a vibration transmitting member transmitting ultrasonic vibration toward a first gripper and formed as one piece, and a second gripper movable between a spaced position where the second gripper is spaced apart from the first gripper and a closed position where the second gripper is put in close to the first gripper. The ultrasonic treatment instrument includes an interlocking actuator increasing, by moving the first gripper in interlock with a movement of the second gripper to the spaced position, a spacing distance between the first gripper and the second gripper in accordance with a movement of the first gripper.
