SYSTEM AND METHOD FOR MEASURING SOLID STRESS IN TISSUES

摘要

A system and method is configured for use with an endoscope, a biopsy needle, and a data acquisition system. The system includes a sensor tip and a pressure sensor coupled to the sensor tip and having at least one piezo-resistor component with an internal-facing side and an external-facing side, and an opening adjacent to the at least one piezo-resistor component to allow fluid access to the internal-facing side and the external-facing side. The system also includes a tubing member with a distal end and a proximal end, the sensor tip coupled to the distal end, the sensor tip and the tubing member configured to be routed through the biopsy needle and connection elements coupled to the proximal end of the tubing member, the connection elements configured to mount the tubing member relative to the biopsy needle and to couple the pressure sensor to the data acquisition system.

1. A device for measuring solid stress in a tumor, the device configured for use with a system including an endoscope, a biopsy needle, and a data acquisition system, the device comprising:
a sensor tip; a pressure sensor coupled to the sensor tip and having at least one piezo-resistor component with an internal-facing side and an external-facing side, and an opening adjacent to the at least one piezo-resistor component to allow fluid access to the internal-facing side and the external-facing side; a tubing member with a distal end and a proximal end, the sensor tip coupled to the distal end, the sensor tip and the tubing member configured to be routed through the biopsy needle; and connection elements coupled to the proximal end of the tubing member, the connection elements configured to mount the tubing member relative to the biopsy needle and to couple the pressure sensor to the data acquisition system.
