Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional surgical devices lack an efficient mechanism for adapting and controlling the stapling process, particularly in linear clamping, cutting, and stapling procedures, which affects staple formation and overall surgical precision.
Innovation Solution
An adapter assembly with a switch actuator, actuation bar, and latch mechanism that allows for precise control of the stapling process by enabling the actuation of a switch to facilitate the movement of staples, ensuring proper staple formation and tissue sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional surgical devices are used for stapling procedures, then basic stapling function is provided, but control precision and staple formation quality are insufficient
Solution Approach 1:
The surgical device is divided into distinct functional modules: a handle assembly containing control mechanisms, an adapter assembly with switch actuators, and a stapling mechanism with movable anvil portion. This segmentation allows independent optimization of each module for precision while managing overall device complexity through modular design.
Solution Approach 2:
An adapter assembly is introduced as an intermediary component between the handle assembly and stapling mechanism. This adapter contains switch actuators that mediate the control signal transmission, enabling precise control of the stapling process without requiring direct complex integration between all components.
2Ease of operation
If a movable anvil portion is implemented for stapling control, then staple formation control is improved, but device complexity increases
Solution Approach 1:
The anvil portion is designed to be movable rather than fixed, allowing dynamic adjustment during the stapling process. This mobility enables precise control over staple formation by adjusting the anvil position relative to the staple cartridge, improving ease of operation while the movement is constrained by guided rails to manage complexity.
Solution Approach 2:
A switch actuator mechanism provides feedback control for the movable anvil portion. The switch actuator detects the position and movement of the anvil, providing feedback signals that enable precise control of the stapling process, improving operability through controlled feedback without requiring overly complex sensing systems.
3Reliability
If intelligent battery power and data gathering are added to surgical devices, then surgical outcomes can be improved, but device complexity and energy consumption increase
Solution Approach 1:
The intelligent battery system operates continuously throughout the surgical procedure, providing uninterrupted power to the stapling mechanism and data gathering systems. This continuous operation ensures reliable surgical outcomes by maintaining consistent performance of critical functions without energy interruptions, while the battery is sized to sustain the entire procedure.
Solution Approach 2:
Clinical data is gathered and stored digitally during the surgical procedure, creating a digital copy of the surgical parameters and outcomes. This data copying enables analysis and improvement of surgical techniques without requiring additional physical measurement devices, reducing energy consumption while improving reliability through data-driven optimization.

AI summary
An adapter assembly includes a switch actuator, an actuation bar, and a latch. The switch actuator is movable between a proximal position, in which the switch actuator actuates a switch, and a distal position. The latch is movable between a first position, in which the latch permits proximal movement of the switch actuator, and a second position, in which the latch prevents proximal movement of the switch actuator. The latch is configured to move from the first position toward the second position in response to the actuation bar moving toward a proximal position.
