Surgical Robot Tool Fixing Device Against Cutting-Load Deformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional surgical tool fixing devices for surgical robots suffer from deformation due to large loads applied during cutting operations, leading to reduced durability and increased maintenance costs, and are difficult to operate for users with weak grips, posing a risk of negligent accidents.
Innovation Solution
A surgical tool fixing device with a sleeve support structure that stabilizes the shaft support sleeve, incorporating a sleeve support and operation handle to prevent deformation and facilitate easy mounting and dismounting of surgical tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the sleeve is screw-coupled to the chuck body with a separation distance without separate support means, then the device structure is simpler, but the sleeve deforms under large loads during cutting operations
Solution Approach 1:
A sleeve support is introduced as an intermediary component between the holder and the sleeve. The sleeve support includes a support protrusion that extends from the holder and a sleeve seating portion that contacts the sleeve, providing a stable support point that prevents sleeve deformation under cutting loads while maintaining structural simplicity.
2Ease of operation
If the operation nut is rotated to release or lock the shaft, then the surgical tool can be separated or mounted, but users with weak grips find it difficult to rotate and may cause erroneous operations
Solution Approach 1:
The operation nut is replaced with an operation handle that has a larger diameter and different geometric shape. The operation handle includes a meshing portion that engages with the operation-force applying portion, providing a larger contact area and mechanical advantage that enables users with weak grips to operate the tool safely and easily.
3Adaptability or versatility
If the sleeve has a long cantilever structure, then the device allows for greater operational freedom, but the sleeve deforms under left-right loads during cutting
Solution Approach 1:
The sleeve support acts as a mediator that provides a stable support point for the cantilevered sleeve. The support protrusion extends from the holder to create a rigid support structure that prevents sleeve deformation under cutting loads while preserving the operational freedom provided by the cantilever configuration.
