Systems and methods for external pressure sensing
First Claim
1. A surgical console, comprising:
- a squeeze plate; and
a pressure sensor module comprising a force sensor;
wherein the squeeze plate is configured to move relative to the pressure sensor module; and
wherein the pressure sensor module is configured to measure a force exerted on the pressure sensor module by a flexible container between the pressure sensor module and the squeeze plate, wherein the force is used to determine a pressure associated with the flexible container;
wherein the pressure sensor module comprises a bag contact plate with a first side that is in contact with the flexible container and a second side that is on an opposing side of the bag contact plate as the first side;
wherein the force sensor measures a force exerted on the force sensor by the second side of the bag contact plate, wherein the force from the bag contact plate is from contact with the flexible container located between the first side of the bag contact plate and the squeeze plate.

Abstract
In various embodiments, a device for delivering pressurized irrigation may include a squeeze plate and a pressure sensor module. The squeeze plate may move relative to the pressure sensor module to apply pressure to a flexible container (e.g., a bag of irrigation fluid) between the squeeze plate and the pressure sensor module. The pressure sensor module may include a pressure sensor to measure a force exerted on the pressure sensor module by the flexible container as pressure is applied to the flexible container from the squeeze plate. In some embodiments, the pressure sensor module may include a bag contact plate and the pressure sensor may measure a force exerted on the bag contact plate by the flexible container located between the bag contact plate and the squeeze plate. In some embodiments, the pressure sensor may sense a pressure associated with the flexible container without an intervening bag contact plate.

12. A surgical system, comprising:
-
a squeeze plate; pressure sensor module comprising a force sensor, wherein the squeeze plate is configured to compress an irrigation bag between the squeeze plate and the pressure sensor module; an irrigation line configured to be coupled to a handpiece such that fluid from the irrigation bag flows through the irrigation line and into the handpiece; wherein the pressure sensor module is configured to measure a force exerted on the pressure sensor module by a flexible container between the pressure sensor module and the squeeze plate, wherein the force is used to determine a pressure associated with the flexible container; wherein the pressure sensor module comprises a bag contact plate with a first side that is in contact with the flexible container and a second side that is on an opposing side of the bag contact plate as the first side; wherein the force sensor measures a force exerted on the force sensor by the second side of the bag contact plate, wherein the force from the bag contact plate is from contact with the flexible container located between the first side of the bag contact plate and the squeeze plate; wherein the surgical system is configured to compare the pressure measured by the pressure sensor module to a predetermined maximum pressure to control movement of the squeeze plate to control the flow of irrigation fluid from the flexible container and into the irrigation line. - View Dependent Claims (13, 14)
