Brain and Spinal Cord Removal Using Suction and Water Flushing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for removing the spinal cord and brain from deceased cattle are time-consuming, messy, wasteful, and risky, involving the removal of the head and vertebrae, which leads to significant waste, contamination, and increased processing time.
Innovation Solution
A method and device for extracting the spinal cord and brain by perforating the skull, using a tube to access the cranial and spinal cavities, and employing a suction tool and high-pressure water hose to flush and remove these tissues without removing the head or vertebrae.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If the head and vertebrae are completely removed to access the spinal cord, then the spinal cord can be removed, but significant waste and contamination occur
Solution Approach 1:
The invention extracts only the necessary portions (spinal cord and brain) through minimal incisions rather than removing entire structures. A perforation is made in the skull and vertebrae to access and remove the spinal cord, preserving the surrounding tissues and minimizing waste while maintaining operational effectiveness.
Solution Approach 2:
The procedure segments the removal process into discrete steps: creating a perforation, inserting extraction tools, removing the spinal cord, and sealing the perforation. This segmented approach allows selective removal of only the spinal cord and brain without requiring complete head or vertebrae removal, thereby reducing waste while preserving ease of operation.
2Object-generated harmful factors
If the head is completely removed to access the brain, then the brain can be removed, but blood loss and mess increase
Solution Approach 1:
The invention extracts only the brain through a perforation in the skull rather than removing the entire head. This minimizes disruption to blood vessels and surrounding tissues, significantly reducing blood loss and mess while maintaining effective access to the brain for removal.
3Reliability
If traditional knife work is used to remove the spinal cord, then the spinal cord can be removed, but the risk of injury to operators increases
Solution Approach 1:
The invention replaces traditional knife-based mechanical cutting with a specialized extraction tool that can be inserted through a perforation. This tool mechanically grasps and removes the spinal cord in one motion, eliminating the need for operators to manually manipulate knives near the spinal cord, thereby improving operator safety while maintaining ease of operation.
4Productivity
If the skull and vertebrae are opened to remove the spinal cord, then the spinal cord can be removed, but the processing time increases
Solution Approach 1:
The invention performs preliminary action by creating a perforation in the skull and vertebrae before spinal cord removal. This pre-established access point allows the extraction tool to be quickly inserted and remove the spinal cord in a single motion, significantly reducing processing time compared to traditional methods that require extensive dissection and manipulation.
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
Reduces waste, minimizes mess and contamination, and significantly decreases processing time while reducing the risk of injury by eliminating the need for knife work and minimizing blood loss.
Implementation Method 1
The operator then uses the tube to remove a spinal cord from the spinal cavity of the deceased animal
Implementation Method 2
employing a suction tool and high-pressure water hose to flush and remove these tissues

AI summary
A spinal cord removal device including a suction tool including a tube, a high-pressure water hose connected to a water source, and a jetter nozzle attached to one end of the high-pressure water hose. The device is inserted into a cranial cavity or spinal cavity of an animal. When water is supplied to the device, water can break up the brain material or spinal material, flushing and cleaning the spinal cavity and cranial cavity.
