Electrocautery End Tool With X-Shaped Jaws for Multi-Axis Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical instruments for electrocautery lack the ability to rotate in multiple directions and intuitively match the movement of a manipulation portion, limiting their effectiveness in laparoscopic and other surgeries.
Innovation Solution
The surgical instrument features an end tool with a pair of jaws that can rotate in two directions, forming an X-shaped structure, allowing for enhanced grip force and enabling pitch, yaw, and actuation motions, and is designed for use with a robot arm or manually.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the end tool is designed with traditional single-direction rotation, then the structure is simple, but it cannot intuitively match the movement of the manipulation portion and limits surgical effectiveness
Solution Approach 1:
The end tool is designed with dynamic multi-directional rotation capability, allowing it to rotate in pitch and yaw directions to adapt to different surgical angles and movements, thereby intuitively matching the manipulation portion's movement while maintaining operational effectiveness
2Force
If the jaws are designed with traditional parallel structure, then the manufacturing is simple, but the grip force is insufficient
Solution Approach 1:
The jaws are designed with an X-shaped asymmetric structure instead of traditional parallel configuration, creating a mechanical advantage that amplifies grip force while the cross-shaped design allows for efficient manufacturing through standardized components
3Adaptability or versatility
If the end tool lacks multi-directional rotation, then the device complexity is low, but it cannot perform pitch, yaw, and actuation motions required for complex surgical tasks
Solution Approach 1:
The end tool incorporates rotation mechanisms that add pitch and yaw dimensions to the traditional actuation motion, enabling three-dimensional movement capability that expands surgical versatility while using compact mechanical designs to control overall complexity
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 instrument provides amplified grip force and efficient cutting and cauterizing capabilities, facilitating precise surgical operations with reduced bleeding by intuitively matching the operator's movements.
Implementation Method 1
Electrical energy supplied through the electrodes may be used to coagulate, bond, or cut the patient's body tissues
