Abstract: A back-up infusion pressure sensor module for use in an ophthalmic surgical console includes a squeeze plate configured to engage with a fluid bag. The back-up infusion pressure sensor module further includes a pressure sensor assembly, having a sensor door and a sensor frame, wherein the sensor door pivots relative to a pin coupled to a top portion of the pressure sensor assembly, configured to cause the sensor door to be biased towards the fluid bag. The pressure sensor assembly comprises a base mounted to the back side of the sensor frame of the pressure sensor assembly, one or more springs, a spring bracket coupled to the one or more springs, and a force sensor in contact with the spring bracket, configured to determine a pressure force against the fluid bag.

Abstract: Embodiments disclosed herein provide a compression system including a squeeze plate, a linkage assembly, and a drive assembly. The squeeze plate is configured to engage with a fluid bag. The linkage assembly comprises a plurality of brackets each coupled to a plurality of linkage sets, where actuation of the linkage assembly causes lateral translation of the squeeze plate. The drive assembly comprises a lead screw disposed through each of the plurality of brackets, an actuator configured to rotate the lead screw to actuate the drive assembly, and a nut assembly coupled to the lead screw and at least one of the plurality of brackets, where the nut assembly is configured to provide a biasing force to maintain a target range of pressure on the fluid bag if the actuator fails.

Abstract: Certain aspects of the present disclosure provide a surgical cassette configured to engage a first plurality of rollers of a first roller head. The cassette comprises a face coupled to a first substrate, the face being at a first angle with respect to the first roller head's axis of rotation and a wall of first substrate being at a second angle with respect to the axis of rotation, wherein the first angle is different from the second angle. The cassette also comprises a first sheet positioned on the wall's surface, wherein the first sheet and the wall form first one or more pump segments configured to engage the first plurality of rollers in a position where force applied by each one of the first plurality of rollers on the first one or more pump segments has a direction that is not parallel to the first roller head's axis of rotation.

IPC: A61M1/00
Abstract: Embodiments disclosed herein provide a surgical cassette including pump assemblies with improved contact between a displacement sensor disposed within a surgical console and a diaphragm disposed within the surgical cassette. Each pump assembly includes a diaphragm retainer ring that provides a sufficient creepage and clearance margin, acts as a lead-in for the displacement sensor, assists in preventing misalignment, and provides robustness for the ultrasonic welding process which couples the diaphragm retainer ring to the surgical console. The diaphragm retainer ring is impregnated with a lubricant so to facilitate seating of the displacement sensor with the cassette. A cantilever portion of the diaphragm retainer ring increases a creepage and clearance margin, as well as increases overall part strength in the event of a collision with the displacement sensor and during ultrasonic welding. An insulator is also provided that further increases the creepage and clearance margin.
