Surgical Device Cutting Element Translation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current laparoscopic gastroplasty procedures face challenges such as increased recovery time, cosmetic scarring, and the 'chopstick' effect due to multiple instrument insertions and interference, which complicates the surgical process and prolongs procedure duration.
Innovation Solution
A surgical device with movable jaws and a cutting element that translates between positions to engage and cut tissue, allowing for precise cutting and fastening without interfering with other instruments, reducing the need for multiple incisions and minimizing surgical time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple abdominal incisions are made for laparoscopic surgery, then surgical access and instrument insertion are improved, but cosmetic scarring and post-operative consequences increase
Solution Approach 1:
The patent combines multiple surgical functions (cutting, stapling, fastening) into a single integrated device that can be inserted through one incision. The device includes a cutting element and a fastening mechanism with multiple fasteners that can be deployed through a single cannula, eliminating the need for multiple separate instruments and incisions.
Solution Approach 2:
The surgical device performs multiple functions through a single instrument: it can cut tissue with the cutting element, deploy fasteners to secure tissue, and manipulate tissue with the jaws. This multi-functional design allows one incision to provide access to all necessary surgical capabilities.
2Adaptability or versatility
If multiple laparoscopic instruments are inserted through the same incision or adjacent incisions, then surgical capabilities are improved, but instrument interference and the 'chopstick' effect increase
Solution Approach 1:
The patent merges multiple surgical functions (cutting, stapling, fastening) into a single integrated device that can be inserted through one incision. The device includes a cutting element and a fastening mechanism with multiple fasteners that can be deployed through a single cannula, eliminating the need for multiple separate instruments and incisions.
Solution Approach 2:
The device nests multiple functional components within a single cannula structure. The cutting element, fastening mechanism, and multiple fasteners are all contained within the same instrument shaft, allowing them to be delivered through a single incision without interfering with each other.
3Ease of operation
If standard laparoscopic instruments are used with multiple incisions, then surgical access is improved, but procedure duration and recovery time increase
Solution Approach 1:
The patent combines multiple surgical functions (cutting, stapling, fastening) into a single integrated device that can be inserted through one incision. The device includes a cutting element and a fastening mechanism with multiple fasteners that can be deployed through a single cannula, eliminating the need for multiple separate instruments and incisions.

AI summary
Methods and devices are provided for cutting and fastening tissue. In one embodiment, a surgical device can be used to at least partially transect a stomach by not cutting and/or not fastening a portion of tissue engaged in an end effector located at the device's distal end. A portion of the stomach can be engaged by the end effector, and the end effector can be actuated to cut and/or to apply one or more fasteners to tissue engaged in a distal portion of the end effector but not to cut and/or apply fasteners to tissue engaged in a proximal portion of the end effector. In a similar way, the surgical device can be used in any surgical procedure in which it is desired to cut and/or fasten a distal portion of tissue engaged by the end effector but not a proximal portion of tissue engaged by the end effector.
