Septal Stapler Segmented Arms Trigger Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current septal surgery tools lack an efficient mechanism for placing surgical staples in septal tissue with ease and precision, particularly in the confined nasal passages, often requiring complex maneuvers and potentially causing discomfort or injury.
Innovation Solution
A septal stapler apparatus with a handle and pair of spaced arms, including a staple arm and tensioning arm, which are activated by a trigger to move staples into position, allowing for precise placement of staples in septal tissue with minimal discomfort and ease of use, accommodating either left or right-handed operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a septal stapler apparatus is designed to place staples in confined nasal passages, then precision of staple placement is improved, but device complexity increases due to the need for spaced arms and trigger mechanism
Solution Approach 1:
The stapler apparatus is divided into two separate spaced arms (first arm and second arm) that can be independently positioned within the nasal passages. Each arm carries staple-holding components, allowing precise placement at different locations while keeping each arm relatively simple in structure
Solution Approach 2:
The spaced arms and trigger mechanism are designed to nest within the confined space of the nasal passage. The arms can be collapsed or positioned close to each other for insertion, then expanded to the spaced configuration for stapling, reducing the effective device size during insertion while maintaining complexity during operation
2Ease of operation
If the stapler uses a trigger mechanism to move arms together, then ease of operation is improved, but device complexity increases due to additional actuating components
Solution Approach 1:
The trigger mechanism combines multiple functions into a single actuating component. Pulling the trigger simultaneously releases the staple from the holding member, activates the actuator to move the arms together, and positions both arms for stapling in one simple motion, improving ease of operation while consolidating complexity into a single integrated mechanism
Solution Approach 2:
The actuator is designed to automatically move the arms together when triggered, without requiring manual manipulation of separate components. The spring-loaded or mechanically-coupled actuator self-activates upon trigger pull, performing the arm movement function automatically and reducing the operational steps required by the user
3Adaptability or versatility
If the arms are spaced apart to accommodate nasal passages, then adaptability to patient anatomy is improved, but device complexity increases due to the need for adjustable or flexible arm configuration
Solution Approach 1:
The arm configuration is designed to be dynamic rather than fixed. The arms can be adjusted between a collapsed position for insertion and a spaced position for stapling, allowing adaptation to different patient anatomies. The mechanical coupling allows the spacing to be modified while maintaining the functional relationship between the arms

AI summary
A septal stapling apparatus includes an instrument body having proximal and distal end portions. A handle at the distal end portion enables a user to hold and manipulate the instrument body. A pair of spaced apart arms are extending from the handle and include a staple arm and a tensioning arm. The body provides a trigger that moves between resting and firing positions. An actuator link moves between first and second positions, the actuator link being moved by the trigger, wherein the actuator link includes a staple moving member that is attached to the staple arm. The staple arm has a staple bank that includes multiple staples. The trigger, actuator link, staple bank, and staple moving member are configured to move a staple to a stapling position when the trigger is pulled. The staple arm and tensioning arm move together when the trigger is pulled.
