A cartridge includes an electrical connection assembly, a first port, a second port, a pumping mechanism, a valve, and a fluid flow sensor. The electrical connection assembly is configured to electrically couple to an electrosurgical unit. The first port is configured to fluidly couple to a fluid source. The second port is configured to fluidly and electrically couple to a surgical instrument. The pumping mechanism is disposed between the first and second ports and is configured to draw fluid from the fluid source and pump the fluid to the surgical instrument. The valve is disposed between the first and second ports and is configured to selectively obstruct the flow of the fluid therethrough. The fluid flow sensor is disposed between the first and second ports and is configured to sense fluid flow therethrough. The fluid flow sensor is configured to electrically communicate with the electrosurgical unit.

A surgical navigation system comprises a computer system, a tracking system and a projector. The computer system includes instructions for performing a surgical plan. The tracking system is electronically connected to the computer system and has a viewing area in which markers can be located within a three-dimensional space relative to the viewing area. The projector is electronically connected to the computer system and has a beam projectable into the viewing area to display a step of the surgical plan based on a location of a marker. A method for guiding a surgical instrument comprises tracking a surgical instrument within a three-dimensional space using a computer-operated tracking system, matching the surgical instrument to a step in a surgical plan for conducting the surgical procedure using the surgical instrument, and projecting a visual instruction into the three-dimensional space for the step in the surgical plan related to the instrument.

A system and/or method for detecting a ferromagnetic object during surgery comprises a probe tip magnetoresistance device configured for insertion into a human or animal cavity and a probe base magnetoresistance device configured for remaining outside the cavity. The system and method detect the ferromagnetic object by comparing the electrical signals generated by the probe tip and the probe base magnetoresistance devices in response to the ambient magnetic field without generating a magnetic field to detect the ferromagnetic object.

The subject matter discloses a system for monitoring tagged items in a medical facility, comprising one or more reader units configured to collect and store tracking data related to tagged items in real time, said monitoring data includes radio frequency tag identification data unique for each tagged item; a medical facility server configured to receive the monitoring data from the one or more reader units, determine whether one or more predetermined rules or conditions are met, and trigger an action based on said determination; wherein the monitoring data comprises identification data and utilization data related to tagged items which are intended for use in the medical facility.

A mobile cart that holds a bag for receiving solid waste generated during a medical or surgical procedure. The cart includes a sensor that monitors whether or not an object containing metal is placed in the bag. A processor monitors the signal output by the sensor. If the sensor signal indicates that an object with a minimal amount of metal is placed in the bag, the processor momentarily asserts an audible alarm and continuously asserts a light alarm. The light alarm remains asserted until turned off. If, while the light alarm is on, the sensor signal indicates a second object with the minimal amount of waste is placed in the container, the processor again momentarily asserts the audible alarm. This provides notice that it may be necessary to investigate the contents of the bag to determine if not one but two or more objects were inadvertently discarded.

A single use medical guidance device capable of attachment to an patient, and designed to facilitate the precise placement of a medical guidance device upon and/or into the patient for inserting or otherwise attaching a medical tool upon the patient, wherein the medical guidance devise is capable or relaying the status of the device (used or new) to any third party user interface.

An electronic device is provided including a processor, an input device coupled to the processor, a memory coupled to the processor; and a module saved in the memory. The module configures the processor to, during a procedure phase of a medical procedure, identify pieces of equipment to be used in the medical procedure using input from the input device; track the pieces of equipment being used in the medical procedure using input from the input device; and account for each of the pieces of equipment at completion of the medical procedure using input from the input device.

Surgical instrument RFID tag reading apparatus (10) comprises an interrogation zone (12) for receiving a surgical instrument set (14) comprising: a plurality of surgical instruments, each having a respective RFID tag containing identification information; an RFID tag reader (16); RF antenna (18) arranged to transmit an RF signal (20) and arranged to receive RF return signals from at least some of the RFID tags; guidance apparatus (22) arranged to cause predetermined relative movement between the RFID tags on the surgical instruments and the RF signal; and a controller (24) arranged to: receive the surgical instrument identification information from the RFID tag reader for each RFID tag from which an RF return signal is received; compare the received surgical instrument identification information with a surgical instrument list of the set; and; determine whether surgical instrument identification information has been received for each of the surgical instruments on the surgical instrument list, and if not, generate an incomplete list alert.

A surgical instrument operable to sever tissue includes a body assembly and a selectively coupleable end effector assembly. The end effector assembly may include a transmission assembly and an end effector. The body assembly includes a trigger and a casing configured to couple with the transmission assembly. An information transmission system transmits instrument information received from a sensor, for example, to a secure server via a secure gateway connected to the instrument. The instrument may be previously tested on a calibration kit to pre-determine and load surgeon-specific settings onto the instrument prior to use.

Embodiments include a fiducial deployment system with a handle configured for actuation of same. A fiducial may include one or more protuberances configured to engage one or more slots in a needle of the system. The needle may be configured to deliver a plurality of fiducials to a target location in serial fashion, one at a time. In certain embodiments, echogenic placement of fiducials may present certain advantages. The handle includes an actuation mechanism with rotatable housing portion or member configured for incrementally or otherwise controlledly deploy one or more fiducials at a time by advancing a stylet through and/or retracting the body of a slotted needle in which fiducials are disposed with a fiducial protrusion extending into the needle slot, which also includes retaining structures that do not impede the needle lumen.
