Surgical Cassette Release Mode Selection Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surgical cassettes in ophthalmic surgical systems often experience accidental release due to the lack of user-selectable release modes, which can disrupt procedures and pose risks during surgeries.
Innovation Solution
A system and method allowing users to select from multiple cassette release modes, including instant, continuous, and delay modes, using a user interface and controller to manage the release process, ensuring controlled and intentional cassette detachment from surgical instrumentation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single release button is used to activate cassette release, then the device structure is simple, but accidental cassette release may occur during surgical procedures
Solution Approach 1:
The system dynamically changes the release mechanism based on user selection, offering different release modes (instant release, continuous press release, delayed release) that adapt to different surgical needs. The controller adjusts the release behavior in real-time based on the selected mode, making the static release button dynamically versatile.
Solution Approach 2:
The invention changes the operational parameters of the release button by introducing multiple release modes with different activation characteristics. The controller modifies the release trigger parameters (instant vs. delayed vs. continuous) to balance simplicity and reliability based on user preference and surgical context.
2Speed
If instant release mode is selected, then cassette release speed is fast, but risk of accidental release increases
Solution Approach 1:
The system allows dynamic selection between different release speed profiles. The instant release mode provides fast release when needed, while the continuous press and delayed modes provide slower, more controlled release when safety is prioritized. The controller adapts the release timing dynamically based on user selection.
3Reliability
If continuous press or delayed release mode is selected, then accidental release prevention is improved, but release speed decreases
Solution Approach 1:
The controller changes the temporal parameters of the release activation based on selected mode. Continuous press mode requires sustained activation, delayed mode introduces a time threshold, while instant mode requires minimal activation time. This parameter adjustment balances safety and speed according to user needs.
4Adaptability or versatility
If multiple release modes are provided, then user flexibility and adaptability are improved, but device complexity increases
Solution Approach 1:
A single release button performs multiple functions by responding differently based on the selected mode. The same physical component (release button) provides instant release, continuous press release, and delayed release functionalities, making the system universal and multi-functional without requiring separate buttons for each mode.
Solution Approach 2:
The controller acts as an intermediary between the release button and the cassette release mechanism. It interprets the button press according to the selected mode and mediates the final release action, allowing complex behavior to emerge from a simple interface through intelligent intermediate processing.

AI summary
A system (100) and computer-implemented method are provided for allowing a user to select the release modality of a surgical cassette (150) so as to control a cassette release mechanism (142,144,182,184). Examples of release modes include an immediate, instant or latching mode, a continuous mode or a delay mode. A user interface (115) can be provided that allows a user to select (250) a cassette release mode for a surgical cassette from a set of cassette release modes, determining that a release request is asserted, and issuing one or more commands (260,265,295) to cause the surgical cassette to be released from a cassette receiver (125) according to the selected cassette release mode. The user can also select whether the release command can be asserted through a release button (145) or the user interface (115).
