Method and system to determine an optimal tissue compression time to implant a surgical element

摘要

An apparatus for determining an optimal amount of tissue compression for applying a surgical element to tissue is disclosed. The apparatus includes a device for compressing tissue which supports a measuring device adapted to detect a tissue parameter upon the compression of tissue. The measuring device communicates with an indicator. Upon compressing tissue, when the measuring device determines that the compressed tissue parameter reaches a predetermined threshold, the measuring device sends a signal to the indicator such that the indicator provides an indication to a surgeon that the threshold has been reached. The measuring device may include a load cell and the tissue parameter may be a viscoelastic reactive force of the tissue per unit time.

1. A method for determining an optimal compression of tissue to apply a surgical element to the tissue, the method comprising:
measuring an initial thickness of the tissue; applying a load to the tissue; determining when a physiological event occurs in the tissue in response to the load applied; measuring the thickness of the tissue at the physiological event; and modulating a surgical instrument based upon the thickness of the tissue at the physiological event.
