AI Technical Summary

Technical Problem

Conventional sleeve gastrectomy tools lack the ability to provide quantitative information during resection, leading to variations in the remaining stomach shape post-surgery, which can result in complications such as gastroesophageal reflux or weight regain due to inconsistent volume adjustments.

Method used

A sleeve gastrectomy assist device with a guide section, expandable section, first measuring section, and monitor section that measures pressure to provide resection position information, ensuring accurate volume adjustment and shape conformity to the patient's stomach.

Benefits of technology

The device allows for precise resection by providing quantitative data, reducing the risk of complications by ensuring the remaining stomach volume is consistent with the target shape, thereby improving surgical outcomes.

Abstract

To provide a sleeve gastrectomy aid device.SOLUTION: The present disclosure relates to a sleeve gastrectomy aid device including: a guide configured to be inserted into a stomach of a patient; an expander configured to be disposed outside the guide and have a volume that changes according to an amount of air therein; a first measurer configured to measure a pressure applied to the expander and have a shape that can change in accordance with a change in the volume of the expander; and a monitor configured to be connected to the first measurer and provide resection position information through a value of the pressure measured by the first measurer.SELECTED DRAWING: Figure 2
