Solution Overview
Problem
Conventional laser treatment methods rely on manual operation, leading to decreased accuracy and prolonged treatment times, affecting the reliability and efficiency of the process.
Innovation Solution
A method and apparatus that utilize a three-dimensional image of the treatment area to set a guided motion path for the laser, including sections for entering, moving within, and reentering the treatment region, with controlled speed and frequency, allowing precise laser irradiation points to be set and followed by a robot arm, enabling automated and efficient treatment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual operation is used for laser treatment, then the operator can flexibly adjust the treatment process, but the accuracy and reliability of the treatment decreases
Solution Approach 1:
The patent replaces manual mechanical operation with an automated robot arm system that executes pre-planned laser irradiation paths. The robot arm is controlled by a control unit that receives treatment plans from a external device, eliminating human manual operation while maintaining treatment flexibility through digital programming. This substitution directly resolves the contradiction by providing both high reliability through automation and operational flexibility through programmable control.
2Productivity
If manual operation is used for laser treatment, then the treatment process can be adapted to individual cases, but the treatment time becomes excessively long
Solution Approach 1:
The patent implements preliminary action by pre-planning the laser irradiation path and parameters using imaging data before treatment. The treatment plan is created in advance by inputting patient data and setting irradiation conditions, then the robot arm automatically executes this pre-planned sequence. This eliminates time-consuming manual adjustments during treatment while maintaining individualized treatment approaches, directly resolving the time efficiency contradiction.
3Measurement precision
If automated robot arm is used for laser irradiation, then the treatment accuracy and speed control is improved, but the system complexity increases
Solution Approach 1:
The patent applies universality by designing the robot arm system to perform multiple functions: positioning the laser, controlling irradiation timing, managing speed variations, and coordinating with imaging systems. The control unit integrates these diverse functions into a single coordinated system, reducing overall complexity despite the advanced capabilities. This multi-functional design achieves high positioning accuracy without proportionally increasing system complexity.
