Solution Overview
Problem
Surgical operation tables with inclining and elevating functions face difficulties in crosswise and lengthwise turning without moving the patient's head position, making it challenging to maintain the patient's posture during procedures like endoscope or microscope surgeries.
Innovation Solution
A surgical operation table equipped with a motion mechanism and hydraulic cylinder devices that allow crosswise and lengthwise turning while maintaining the patient's head position, using slide and elevating motions to prevent positional deviation during these maneuvers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the table is crosswise turned or lengthwise turned to change patient posture, then the table can be repositioned for different surgical approaches, but the patient's head position moves which creates surgical difficulties
Solution Approach 1:
The slide mechanism is activated before the turning mechanism to pre-position the table in a way that compensates for the upcoming rotational movement. This preliminary sliding action ensures that when the table turns crosswise or lengthwise, the patient's head remains at the intended position relative to the surgical field, thereby maintaining both posture adaptability and position stability
Solution Approach 2:
The slide mechanism acts as an intermediary between the patient and the turning mechanism. By introducing this intermediate degree of freedom, the system can perform combined sliding and turning motions that independently control both the table's orientation and the patient's head position, resolving the contradiction between posture change and position stability
2Manufacturing precision
If the table is fixed at a predetermined inclination for head surgery, then the patient's head position remains stable, but the table cannot be easily turned when posture adjustment is needed
Solution Approach 1:
The system transitions from a static fixed-inclination state to a dynamic coordinated motion state. The control mechanism enables the table to dynamically adjust both inclination and horizontal position during the turning operation, allowing the table to maintain head position stability while achieving the necessary posture changes through real-time motion coordination
3Manufacturing precision
If the table slides in opposite direction during crosswise turning, then the patient's head position is maintained, but the mechanism complexity increases
Solution Approach 1:
The slide mechanism and turning mechanism are merged into a coordinated system where both functions operate simultaneously rather than sequentially. The control mechanism integrates the control of both mechanisms, allowing them to work together as a unified system that achieves head position stability while performing table turning, thereby managing complexity through functional integration
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
Enables smooth crosswise and lengthwise turning of the table without moving the patient's head, reducing burdens on both the patient and the doctor, especially during endoscope or microscope surgeries by maintaining the patient's posture effectively.
Implementation Method 1
a cylinder device that crosswise turning or lengthwise turning the table by supplying or discharging a working oil and extending and contracting a rod by a pressure of the working oil
Implementation Method 2
another cylinder device that is supplied with a working oil that is discharged by an extending and contracting motion of the rod by the first cylinder device, and slides the table by extending and contracting a rod by a pressure of the working oil

AI summary
A surgical operation table is provided, which is capable of crosswise turning a table without changing a position of a patient as much as possible. In a surgical operation table S including a table 15 for laying a patient thereon, motion mechanism sections 35, 20, 25, 70, 60, 65 and 80 that slide, crosswise turn, lengthwise turn, and elevate the table 15, and a base 2 that supports the table 15 via the motion mechanism sections 35, 20, 25, 70, 60, 65 and 80, position holding device is included, which crosswise turns or lengthwise turns the table 15 without changing the position of a head part of the patient laid on the table 15.
