Rotatable Jaw Surgical Device for Articulated Tissue Clamping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional linear clamping, cutting, and stapling surgical devices face challenges in maneuverability and hemostatic effectiveness due to limited angle movement and insufficient clamping force, making it difficult to position and securely clamp tissue during surgical procedures.
Innovation Solution
A surgical device with a jaw portion pivotably connected to a shaft portion, allowing for articulation and enhanced clamping force, featuring a driver system with rotatable drive shafts to pivot and rotate the jaw portion relative to the shaft, enabling precise tissue positioning and secure clamping, cutting, and stapling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional linear clamping device is used, then the structure is simple, but the maneuverability is poor and the jaw cannot be positioned at various angles
Solution Approach 1:
The jaw portion is made dynamically movable relative to the shaft portion through a hinge connection, allowing the jaw to pivot between multiple angular positions. This dynamic capability enables the jaw to adapt to different tissue locations and angles during surgical procedures, significantly improving maneuverability while maintaining a relatively simple overall structure.
2Force
If a conventional linear clamping device is used, then the device is simple, but the clamping force is insufficient for secure tissue closure
Solution Approach 1:
The clamping mechanism is segmented into two independent jaw portions (first jaw and second jaw) that can move relative to each other. Each jaw can be independently actuated through the hinge mechanism, allowing for distributed clamping force application across the tissue. This segmentation enables secure clamping without requiring excessive force in a single location, improving hemostatic effectiveness while maintaining mechanical simplicity.
3Adaptability or versatility
If the jaw portion is made rotatable and articulating, then the maneuverability improves, but the device complexity increases
Solution Approach 1:
The hinge connection serves multiple functions simultaneously: it enables articulation of the jaw portion relative to the shaft, allows rotation of the jaw about its longitudinal axis, and provides the mechanical advantage needed for clamping. This multi-functionality is achieved through a single, simple hinge mechanism rather than multiple separate components, thereby improving adaptability while minimizing the increase in device complexity.

AI summary
A surgical device is provided that includes a jaw portion, having a first jaw in opposed correspondence with a second jaw, the second jaw including a surgical member. The surgical device may include a shaft portion coupled to a proximal end of the jaw portion and at least one motor configured to rotate the jaw portion relative to the shaft portion, to move the jaw portion relative to the shaft portion, move the first jaw relative to the second jaw and move the surgical member within the second jaw. The surgical member may be prevented from moving within the second jaw unless the first jaw is in a closed position relative to the second jaw. Advantageously, the surgical member may include one or both a cutting element or a stapling element, disposed within one of the jaws.
