A system and method for configuring a surgical device are disclosed, one embodiment of the system comprising; an interface operable to receive data; a portable component, comprising an identifier operable to store and transmit a set of data; a memory, the memory storing criteria; and a controller, wherein the controller, the memory and the interface are included in the surgical device, and wherein the controller is operable to configure the surgical device based on the set of data transmitted from the identifier and received at the interface. The identifier can be an RFID tag and the interface can be an RFID interface comprising an RFID reader operable to transmit a radio frequency (RF) instruction to activate the RFID tag of the portable component, and a microcontroller operable to cause the RFID reader to transmit the RF instruction. The portable component can be an identification tag that can be attached to the user. The criteria can be user authorization data that is stored in the memory and the controller is operable to determine whether a user associated with the portable component is authorized to use the surgical device based on whether the set of data transmitted from the identifier and received at the interface satisfies the criteria stored in the memory. The criteria can also be an algorithm that the controller applies to the set of data received from the identifier to determine whether the user is authorized to use the surgical device. The controller can cause the surgical device to be disabled if it is determined that the user is not authorized to use the surgical device (e.g., the surgeon, technician or patient is at the wrong surgical device).

A surgical device includes a plurality of cameras integrated therein. The view of each of the plurality of cameras can be integrated together to provide a composite image. A surgical tool that includes an integrated camera may be used in conjunction with the surgical device. The image produced by the camera integrated with the surgical tool may be associated with the composite image generated by the plurality of cameras integrated in the surgical device. The position and orientation of the cameras and/or the surgical tool can be tracked, and the surgical tool can be rendered as transparent on the composite image. A surgical device may be powered by a hydraulic system, thereby reducing electromagnetic interference with tracking devices.

System and method for identifying a component, such as an optical probe or pneumatic scissors, of an ophthalmic surgical device. A component of a surgical device includes an identifier, such as a RFID tag. Data from the RFID tag is transmitted to a RFID reader in the device. A controller determines whether the component corresponding to the received data is operable with the surgical device based on criteria, such as whether the received data is an authorized code that matches data stored in memory or whether the received data solves or satisfies an algorithm. The authorized codes are selected from a larger set of available codes. The controller enables or disables the operation of the device with the component based on whether the criteria is satisfied, the number of uses of the component, an amount of time that has passed since the component has been used, or a geographic location. The RFID data can also be used to calibrate the surgical device for use with the particular component and for inventory and monitoring purposes.

Provided herein are patient-specific surgical device that allow for a stable fitted position for use in shoulder surgery. The patient-specific surgical devices may have different functions such as a function as a guide.

A virtual control system for an operating room establishes virtual control devices to control surgical equipment and patient monitoring equipment and to display control, status and functionality information concerning the surgical equipment and condition information of the patient. The virtual control devices permit direct interaction by the surgeon while maintaining a sterile field, and avoid the use of actual physical devices and electrical cables connecting them to the surgical equipment.

Surgical apparatus includes bipolar electrodes and tissue-shearing blades configured to electrically contact tissue for electrocauterization thereof prior to shearing contact of the cutting blades with the tissue over wide angles of presentation of the tissue to the electrodes and blades. Extensions or protrusions disposed along facing edges of the electrodes separate the level at which tissue is electrically contacted by the electrodes from the level at which tissue is sheared by the cutting blades.

A device and method useful for guiding insertion of a surgical device with image guided surgery. The device includes a base that may be connected to a fixation device to hold the device in place, and a guide for the surgical device. The guide is connected to the base by a semispherical ball joint, which allows the trajectory of the guide to be adjusted. The device includes an adjustable depth stop that controls the distance the surgical device is inserted into the patient. A positional indicator is attached to the depth stop. An insertion indicator signals when the depth stop is set so as to limit the insertion distance to that necessary to treat the target tissue within the patient.

The present invention provides a surgical footswitch that includes a base, a pedal, an encoder assembly, a wireless interface, and an internal power generator. The pedal mounts upon the base and pivots. The encoder assembly couples to the pedal. As the pedal pivots, the encoder assembly translates the mechanical signal of the pedal into a control signal based on the pedals position and/or orientation. The wireless interface couples the encoder assembly to receive the control signal. The wireless interface also couples the surgical footswitch to a surgical console operable to control and direct surgical equipment. The wireless interface passes the control signal from the encoder to the surgical console, which then directs the surgical equipment based on the control signal. This wireless interface eliminates the tangle of wires or tethers, which may be a hazard in the surgical theater. The internal power generator translates footswitch movement into stored energy to eliminate potential failures of the footswitch during a procedure and overcome the need to replace batteries within the footswitch.
