Surgical Motor Control Adaptation for Overheating Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surgical motor systems face limitations in application due to rapid speed readjustments causing overheating, particularly in applications requiring less quick adjustments, leading to restricted usage and increased costs due to the need for different motor systems for various medical procedures.
Innovation Solution
A drive control device with a parameter setting mechanism that adapts the control or regulation profile of the electric motor based on the current medical application, allowing for optimal torque/speed characteristics, reducing overheating, and enabling the use of a single motor system for diverse applications by varying control modes through software adjustments.

Engineering Contradiction Analysis
1Stability of the object's composition
If rapid speed readjustment is implemented to counteract speed drops, then speed stability is improved, but additional current impulses occur causing motor overheating
Solution Approach 1:
The control device dynamically adapts the control profile based on the detected surgical application. For applications with frequent load changes (e.g., craniotomy), the control profile enables rapid speed readjustment. For applications with stable loads (e.g., bone segment milling), the control profile limits rapid readjustments to prevent excessive current impulses and overheating.
Solution Approach 2:
The invention changes the control parameters (control profile) according to the detected surgical application. By selecting different control profiles tailored to specific applications, the system optimizes the balance between speed stability and energy efficiency, preventing overheating while maintaining appropriate speed regulation.
2Reliability
If different motor systems are used for different medical applications, then reliability is improved, but device complexity and costs increase
Solution Approach 1:
The invention makes a single motor system universal by equipping it with a control device that can detect the surgical application and automatically adapt the control profile. This allows one motor system to reliably serve multiple surgical applications (drilling, milling, sawing, craniotomy) without requiring separate specialized motors for each application.

AI summary
The invention discloses a drive control device for a surgical motor system with a motor control unit (MS) for controlling and/or regulating an electric motor (M) driving a surgical instrument (W). To be able to use the drive control device for the widest variety of applications, according to the invention a parameter-specifying device (PV) is connected upstream of the motor control unit (MS) which parameter-specifying device determines the current medical application on the basis of a detected state or state development of the surgical motor system, particularly of the electric motor (M), selects a control mode suitable for this medical application and specifies to the motor control unit (MS) such control and regulation parameters that the control and regulation profile of said electric motor (M) corresponds to the selected control mode.
