STAPLE CARTRIDGE TISSUE THICKNESS ANALYSIS SYSTEM Russian patent published in 2018 - IPC A61B17/68 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medical equipment, specifically to surgical instruments. Staple cartridge for use in a surgical stapler comprises a staple body comprising a proximal end and a distal end, a tissue thickness sensing module coupled to said distal end of said staple body, wherein said tissue thickness sensing module comprises a controller, a sensor, wherein the controller is configured to detect a power key removably positioned relative to said tissue thickness sensing module. Controller is configured to maintain the tissue thickness sensing module in a low-power state while the power key is present, and wherein the controller is configured to transition the tissue thickness sensing module to an active state when the power key is removed. Method for controlling the power supply of the staple cartridge assembly having a tissue thickness sensing module is also provided.

EFFECT: use of a group of inventions ensures that the thickness of tissue clamped at the end clamp is matched to the optimum range for said staple cartridge.
