AI Technical Summary
Technical Problem
In minimally invasive surgery, the inability to accurately select the appropriate staple cartridge size can lead to excessive tissue pressure or rupture, affecting surgical efficiency and safety.
Method used
By installing a human tissue pressure measuring device on a surgical instrument, pressure data during the pressing process can be acquired in real time, generating a real-time pressure-time characteristic curve. This curve is then matched with a pre-established database of standard pressure-time characteristic curves to recommend the optimal staple cartridge size.
Benefits of technology
It enables the rapid and precise selection of the appropriate staple cartridge size in minimally invasive surgery, improving surgical efficiency and safety, and avoiding tissue damage.

Abstract
This invention discloses a method for selecting a staple cartridge based on human tissue measurement. The method includes: acquiring a standard characteristic curve database containing multiple pre-stored standard pressure-time characteristic curves; installing a human tissue pressure measuring device into the surgical instrument staple cartridge holder; performing a compression operation on the human tissue to be tested to acquire real-time pressure measurement data and generate a real-time pressure-time characteristic curve; matching the real-time pressure-time characteristic curve with several standard pressure-time characteristic curves in the database; selecting the standard pressure-time characteristic curve with the highest matching degree; using the corresponding recommended staple cartridge model as the recommended staple selection result; and selecting the corresponding staple cartridge model for the human tissue to be tested based on the recommended staple selection result. This method for selecting a staple cartridge based on human tissue measurement can obtain a suitable staple cartridge size recommendation for the current surgery by performing real-time pressure measurement on the human tissue and comparing it with pre-stored data in the database.
