Locally Powered Stapler Anvil With Contact And Orientation Lights
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In surgical procedures involving end-to-end anastomosis, locating and orienting the proximal and distal portions of a circular stapler within a patient's body can be challenging, especially when the stapler is inserted through a naturally occurring orifice, making it difficult to ensure proper alignment and operation.
Innovation Solution
The stapler is equipped with illumination systems, including trocar lights, radial and longitudinal rows of lights, and anvil lights, which provide visual feedback on the stapler's location and orientation within the patient, ensuring proper alignment and operation.

Engineering Contradiction Analysis
1Object-affected harmful factors
If the stapler is inserted through a naturally occurring orifice, then the procedure is less invasive, but it becomes difficult to locate and orient the proximal and distal portions of the stapler within the patient's body
Solution Approach 1:
The patent applies color changes by using illuminated elements (lights) on the stapler that emit visible light to indicate orientation and position. The lights create visual cues that allow the surgical team to detect the stapler's location and orientation within the patient's body during the procedure, directly resolving the detection difficulty while maintaining the minimally invasive approach.
2Difficulty of detecting and measuring
If illumination systems are added to the stapler, then visibility and orientation are improved, but device complexity increases
Solution Approach 1:
The illumination system is segmented into multiple independent light sources positioned at different locations on the stapler (proximal end, distal end, and circumferential lights). This segmentation allows each light element to serve a specific orientation-indication function, improving visibility while keeping each individual component simple and modular, thus managing overall device complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The illumination systems enhance the visibility and orientation of the stapler, facilitating precise alignment and operation, thereby improving the accuracy and efficiency of the anastomosis procedure.
Implementation Method 1
an anvil including an anvil surface configured to compress tissue against the deck surface
Implementation Method 2
The stapling head assembly further includes a first longitudinal row of lights positioned on a surface of the tubular casing and extending parallel to a longitudinal axis of the stapling head assembly

AI summary
Disclosed is an anvil for a surgical stapler, the anvil being locally powered and including a contact indication with light indicator. The light indicators provide feedback as to the status of the anvil. The anvil can include a battery or capacitor-based circuit, which can be charged locally or via a power source on the handle.
