Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for manufacturing vitreous body surgical probes often result in burrs on the end inner surface, making it difficult to achieve a flat end inner and outer surface, which is crucial for proximity to the retina without damaging it.
Innovation Solution
A method involving the simultaneous cutting and welding of a steel plate to form the end of a vitreous body surgical probe using an energy beam, ensuring both surfaces are flat and reducing the need for additional processing steps, allowing for a slanted surface configuration if required.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If deformation processing by squeezing is used to form the end part, then the end outer surface can be formed nearly flat, but burrs easily form on the end inner surface
Solution Approach 1:
The patent replaces the mechanical squeezing deformation process with a laser-based energy beam processing method. The laser beam melts and fuses the pipe end material to form a flat end surface, eliminating the burr formation problem associated with mechanical squeezing while achieving the desired flat outer surface morphology.
Solution Approach 2:
The patent changes the processing parameters from mechanical force-based deformation to energy beam-based melting and fusion. By controlling laser power, scanning speed, and beam focus, the process achieves flat end surfaces on both inner and outer surfaces without generating burrs, fundamentally altering the physical state and processing mechanism.
2Ease of operation
If the end inner surface is not flat, then it is difficult to bring the cutting member near the end part, but making the distance long requires the opening to be farther from the retina
Solution Approach 1:
The patent uses laser energy beam processing to create a flat end inner surface, enabling the cutting member to be positioned close to the end part without mechanical interference. This eliminates the need for increased distance D while maintaining ease of operation for cutting member sliding and positioning.
3Manufacturing precision
If additional processing steps are added to eliminate burrs and achieve flat surfaces, then surface quality improves, but manufacturing complexity and workload increase
Solution Approach 1:
The patent combines the end surface formation process into a single laser-based melting and fusion step that simultaneously creates flat inner and outer surfaces without generating burrs. This eliminates the need for separate deburring, grinding, or polishing operations, reducing manufacturing complexity while achieving high surface quality.
Solution Approach 2:
The patent replaces multiple mechanical processing steps (squeezing, deburring, grinding) with a single laser energy beam processing step. This substitution simplifies the manufacturing process while achieving superior surface quality on both inner and outer surfaces of the end part.

AI summary
There is provided a method of manufacturing a vitreous body surgical probe that is easily manufactured and has a flat end outer surface and a flat end inner surface. A method for manufacturing a vitreous body surgical probe (10) includes the steps of: bringing a steel plate (30) in contact with an end surface of a steel pipe (20); and irradiating an energy beam (50) from the steel plate side along the outer circumference of the pipe end surface. The steel plate is cut through irradiation of the energy beam (50), and the pipe (20) and the steel plate (30) are welded together simultaneously. Alternatively, a step of using the same energy beam for cutting and welding the steel plate may be added.
