The invention includes systems and methods for controlling devices including surgical instruments using a wireless footswitch. The systems of the invention include a wireless footswitch, a footswitch adapter, and an electric console for powering and controlling surgical instruments. The systems of the invention further include a wireless footswitch for controlling battery powered surgical instruments. The methods of the invention include syncing a wireless footswitch with a controlled device or a wireless footswitch adapter using a lower power wireless mode, then signaling the controlled device or wireless footswitch adapter using a higher power wireless mode. The systems and methods of the invention include using a wireless device or wireless footswitch adapter to monitor transmissions from other wireless devices to prevent syncing with the wireless footswitch adapter using the same channel or network identification as other wireless devices or wireless footswitch adapters.

Graphical user interface system and method for displaying and controlling a surgical device, such as a device used in phacoemulsification procedures, are disclosed. A graphical user interface is displayed on a display screen and includes one or more representations of operating parameters, such as aspiration rate, vacuum, and power that are used to control the surgical device. A parameter is adjusted by moving a portion of a representation from a first location on the display screen to a second location on the display screen to change the operating parameter and control the surgical device.

The present disclosure discloses a control end of a surgical instrument, which comprises a housing and a power assembly, the housing comprises a first body and a second body, a first cavity for accommodating the power assembly is provided between the first body and the second body, and the power assembly is detachably mounted in the first cavity.

Aspects of the present disclosure are presented for managing simultaneous outputs of surgical instruments. In some aspects, methods are presented for synchronizing the current frequencies. In some aspects, methods are presented for conducting duty cycling of energy outputs of two or more instruments. In some aspects, systems are presented for managing simultaneous monopolar outputs of two or more instruments, including providing a return pad that properly handles both monopolar outputs in some cases.

This document relates to devices and methods for the treatment of heart conditions. For example, this document provides devices and methods for treating heart failure with preserved ejection fraction, including diastolic heart failure, by performing a pericardial modification procedure.

A system for validating data purportedly generated in a medical procedure is disclosed. The system includes a medical hub, at least one remote server communicatively coupled to the medical hub, and a medical instrument communicatively coupled to the medical hub. The system is configured to access the data, validate the data to determine if the data is validly generated by the medical procedure, determine that the data contains at least one flaw or error, and improve data integrity by preventing the at least one flaw or error from being integrated into a larger dataset associated with the at least one remote server.

A tensioner tool for assessing joint laxity is disclosed. The tensioner tool comprises a pair of pivotally coupled arms, each arm comprising a proximal handle portion, a distal portion, and an insertion tip selectively coupled to the distal portion. The pair of arms pivot between a compressed configuration for insertion within the joint and an expanded configuration for distraction of the joint by applying a force to the handles, thus spreading the insertion tips. The tensioner tool also comprises a force sensor configured to measure the force applied to the handle portion and a positional sensor configured to measure a separation distance between the pair of arms. The tensioner tool also comprises a processor configured to calculate a distraction force at the insertion tips based on the measured force and to calculate a tip distance between the insertion tips based on the measured separation distance.

A method for constructing a modular surgical system is disclosed. The method comprises providing a header module comprising a first power backplane segment, providing a surgical module comprising a second power backplane segment, assembling the header module and the surgical module to electrically couple the first power backplane segment and the second power backplane segment to each other to form a power backplane, and applying power to the surgical module through the power backplane.

A neuromonitoring system utilizes transcutaneous, trans-abdominal nerve root stimulation to monitor the health and status of the motor neural pathways of the lower extremities during the portions of a surgical procedure in which a tissue retraction assembly is used to maintain an operative corridor. A method of monitoring the status of nerve during a spinal surgical procedure delivers a transcutaneous, trans-abdominal stimulation signal to the spine. A determination is made of a stimulation threshold required to elicit a neuromuscular response from the stimulation signal.

Described is a surgical device to retain and move an organ during surgical operations, which makes it possible to easily prepare the system for holding the organ and avoids the need both for a dedicated access trocar for exclusive use and the insertion of an operating member connected irreversibly to the surgical device. The surgical device minimises the risk of tearing and/or bleeding of the organ following the actions applied on the same organ during the surgical operation.
