Surgical Instrument Holding Device Bracket Detection Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The accuracy of detecting the positions of adapters and separators in surgical instrument holding devices is compromised due to their rotation with the surgical instrument, leading to potential inaccuracies and safety issues during surgical operations.
Innovation Solution
A surgical instrument holding device with a detecting mechanism attached to a bracket that supports the holding body in a rotatable manner, featuring detecting pins and units that detect the attachment states of the separator and adapter through their movement, ensuring accurate detection without rotating with the holding body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the detecting mechanism is attached to the holding body, then it can detect the position of the surgical instrument, but the detection accuracy deteriorates due to rotation of the holding body
Solution Approach 1:
The detecting mechanism is extracted from the rotating holding body and attached to the stationary bracket. This separates the detection function from the rotating components, allowing accurate position detection without the interference of rotational movement. The detecting pins remain fixed on the bracket while detecting the positions of rotating components like the separator and adapter.
Solution Approach 2:
The bracket serves as an intermediary structure that connects the stationary base to the rotating holding body. By attaching the detecting mechanism to the bracket rather than the holding body, the system uses the bracket as a stable reference frame that does not rotate, thereby maintaining detection accuracy while still allowing the holding body to rotate freely.
2Reliability
If the detecting mechanism rotates with the holding body, then it can track the surgical instrument position, but the detection system becomes complex and less reliable
Solution Approach 1:
The detecting mechanism is extracted from the rotating assembly and fixed to the stationary bracket. This eliminates the complexity of making the entire detection system rotate while still enabling it to accurately track the positions of rotating components through fixed detecting pins that interact with the rotating separator and adapter.
3Adaptability or versatility
If multiple components (separator, adapter, surgical instrument) are detachably connected, then the device is more versatile, but the risk of unexpected position changes increases
Solution Approach 1:
The detecting mechanism provides continuous feedback on the attachment states and positions of the separator, adapter, and surgical instrument. The detecting pins monitor whether these detachable components are properly attached and positioned, allowing the system to detect and alert to any unexpected position changes or improper attachments, thereby maintaining reliability despite component interchangeability.

AI summary
A surgical instrument holding device includes an adapter from which a surgical instrument is detachable, a separator from which the adapter is detachable, a holding body from which the separator is detachable, a driving body configured to support the holding body in a rotatable manner and apply a driving force to the holding body, and a detecting mechanism configured to detect a state of attachment of the separator to the holding body and a state of attachment of the adapter to the separator. The driving body includes a driving force transmitting mechanism configured to transmit the driving force to the holding body and a bracket by which the driving force transmitting mechanism is supported, and the detecting mechanism is disposed on the bracket.
