Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In complex endoscopic surgeries, the existing medical instrument holding devices require multiple units to accommodate manipulators with multiple treatment instrument channels, leading to cluttered operating rooms and inefficient operation.
Innovation Solution
An electric medical instrument fitting with a fitting body, drive units for second medical instruments, and an intermediate member, which allows for the attachment and detachment of observation devices and manipulators, featuring channel holes for treatment instruments and joint drivers to adjust the position and posture of treatment portions, with the center of gravity optimized to reduce clutter and enhance operability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple medical instrument holding devices are used to accommodate manipulators with multiple treatment instrument channels, then the capacity to hold more instruments is improved, but the operating room becomes cluttered and operation efficiency decreases
Solution Approach 1:
The patent combines multiple medical instrument holding devices into a single integrated device that can hold an endoscope and multiple manipulators simultaneously. The holding unit includes a holding portion with multiple holding ports that can accommodate different instruments, merging the functions of separate devices into one unified structure, thereby reducing clutter while maintaining instrument capacity
Solution Approach 2:
The medical instrument holding device is designed with universal functionality to hold various types of instruments including endoscopes and multiple manipulators with different treatment instrument channels. The holding portion can adapt to different instrument configurations, providing multi-functional capability in a single device that improves both capacity and space efficiency
2Device complexity
If the center of gravity of the fitting body is not optimized, then the structural design is simpler, but the balance and stability of the system deteriorates
Solution Approach 1:
The patent positions the center of gravity of the fitting body at a specific location to achieve gravitational balance. By carefully designing the weight distribution and positioning heavy components strategically, the system achieves gravitational equilibrium that ensures stable operation, with the extension line of the center axis of the fitting portion passing through the center of gravity of the entire fitting body

AI summary
The electric medical instrument fitting is attached to a medical instrument holding device. The electric medical instrument fitting includes a fitting body, drive units for a plurality of second medical instruments, and an intermediate member. The fitting body has a fitting portion that enables attachment/detachment of a first medical instrument which can be arranged with an observation device and provided with channel holes for inserting treatment instruments, or which is provided with an observation device. The drive units for the second medical instruments can each be detachably connected with each second medical instrument provided with an insertion portion to be inserted into each channel hole, with a treatment portion being provided on the side of a distal end thereof. Each of the drive units for the second medical instruments is provided with a joint driver, an advancing/retreating driver and a rotation driver, for changing the position and the posture of the treatment portion. Each of the drive units for the second medical instruments has a center of gravity set at a predetermined position of a roll axis of the rotation driver, with the position of the roll axis being apart from a fitting surface by a predetermined distance. The intermediate member is arranged at the fitting body which is attached with the plurality of medical instrument drive units, a center of gravity of the entirety being set on an extension line of a center axis of the fitting portion.
