  • Patent number: 8149108
    Abstract: A system and method for controlling one or more medical devices by a remote console. The remote console communicates wirelessly with a central control unit that connects to one or more of the medical devices. To conserve battery power and simplify operation, the remote console is configured to automatically power on and initiate a wireless connection in response to being brought into proximity of the central control unit. According to another embodiment, the remote console automatically powers on and terminates any previously established wireless connections when brought into proximity of the central control unit.

  • Publication number: 20120002394
    Abstract: An LED based light source unit for an endoscopic imaging system produces illumination for a camera through an endoscope. The light source unit includes an array of LEDs mounted to a thermally conductive substrate, a light guide to collect light emitted from the LEDs and to couple the light into a group of optical fibers within the endoscope, and an interface to allow the light source unit to be removably attached to the endoscope at the endoscope's external light port. The LEDs therein may be overdriven by power for increased light output. When the LEDs reach their lifetime, the light source unit can be discarded.

  • Publication number: 20110087069
    Abstract: A system for remotely controlling multiple medical devices. Included in the system are at least a first medical device and a second medical device, each of which are capable of performing one or more functions. Also included is a remote control unit having at least a first switch and a second switch. Connected to each of the medical devices is a controller that can simultaneously dispatch one or more device command signals to each of the medical devices in response to receiving one or more remote command signals from the remote control unit, thereby allowing a user to remotely and simultaneously control one or more functions associated with each of the medical devices.

  • Patent number: 7846150
    Abstract: A system for controlling one or more medical devices by a remote console. The remote console communicates wirelessly with a central control unit that connects to one or more of the medical devices. To minimize the possibility that a medical device will be activated by a stray or unauthorized wireless command signal, the central control unit must synchronize with the remote console and establish a secure communication link with it before the central control unit will respond to a wireless command signal transmitted by the remote console.

  • Publication number: 20100241116
    Abstract: An electrosurgical system includes an electrosurgical probe connected to a control console, wherein the probe is capable of coagulating and ablating tissue depending on a selected operating mode. Before operating the system, probe-specific data stored in a memory device associated with the probe is read by a processing device in the console. The data includes source impedance values specific to a coagulation or cutting mode of operation. A constant duty cycle value for a modulated cutting mode also is provided. Depending on the operating mode selected, an RF generator adjusted to have a predetermined source impedance value provides a voltage value to the probe. During the duty-cycled mode, the RF generator generates an instantaneous voltage value output for a duty cycle portion that is less than 100% of a time period, which value is no less than a maximum continuous average voltage value for the electrosurgical probe.

  • Publication number: 20100160910
    Abstract: An electrosurgical tool for cauterizing or ablating patient tissue, which tool includes a tubular shaft which defines therein a conduit in communication with a suction source and which mounts an electrode at the distal end thereof. An electrode support element is provided at the distal end of the shaft for mounting and insulating the electrode. The support element and the electrode together define a suction opening at the treating surface of the electrode which minimizes clogging of the tool.

  • Patent number: 7668450
    Abstract: An LED based light source unit for an endoscopic imaging system produces illumination for a camera through an endoscope. The light source unit includes an array of LEDs mounted to a thermally conductive substrate. The light source unit is integrated into the proximal end of an endoscope and coupled directly to the optical fibers running to the tip of the endoscope. A plurality of such light source units may be integrated into the housing of an endoscope. Light emitted from each light source unit is directed to a distinctive section of the endoscope's tip and a doctor may control light output of each individual light source unit during a surgery.

  • Publication number: 20090080348
    Abstract: A network system prevents portable wireless remote control consoles from unintended activation of a medical device by determining if the console is located in a working space within a medical care room. Transceiver locator devices determine the position of the remote control consoles and send information to room control units indicating when a console is within the desired working space. The room control unit receives signals from the remote control console in the working space to control medical devices. The room control unit can also determine which of multiple remote control consoles within the working space is permitted to operate the medical devices. Each room control unit can send a presence output to the remote control console to enable use thereof. The remote control console can have an orientation sensor or a grip detector to prevent unintended operation thereof.

  • Publication number: 20080188848
    Abstract: A surgical tool arrangement including a powered handpiece which cooperates with a combined electrosurgical and mechanical cutting instrument. The electrosurgical and mechanical cutting instrument includes an outer static housing element which defines an electrode for delivering electrical energy to the surgical site, and a cutting element disposed within the outer housing and movable relative thereto for manipulating patient tissue. The electrosurgical and mechanical cutting instrument is an integral component attachable to the surgical tool to provide multiple functions in a single instrument, such as cauterization, ablation and mechanical cutting, without the need for attachment of additional housing structures or other adapters. The tool arrangement also includes a universal handpiece which is capable of accepting and operating a number of different surgical instruments, each having one or multiple functions.

  • Publication number: 20080140158
    Abstract: A wireless foot control apparatus allows an operator to control multiple medical devices during an endoscopic medical procedure. The apparatus comprises a control console with controls designed for foot operation to control various medical devices. The controls include one or more foot pedals and foot switches to control the devices, including a selection switch to allow selection of the device to be controlled at a particular time. The console transmits signals over a wireless medium, to cause a remote receiver unit to select the device to be controlled and to control the selected device over a wired medium, in response to operation of the foot controls. The console may include a rechargeable battery, which may be sealed within the console's housing and charged inductively when the console is placed in a charging station. The receiver unit and the charging station can be separate units or integrated within a single housing.
