  • Patent number: 11617682
    Abstract: A foot pedal device configured to provide force feedback to an operator during ophthalmic surgery is described. The foot pedal device includes a processor and a memory containing instructions which, when executed by the processor, cause the processor to transmit, in response to a movement of a moveable member, a control signal to a surgical console for initiating an action of an ophthalmic surgery tool coupled with the surgical console. The foot pedal device includes a force feedback mechanism configured to selectively apply a resistance force in opposition to the movement of the movable member. The memory contains instructions which, when executed by the processor, cause the processor to receive, from the surgical console, a trigger signal, and send a force feedback signal to the force feedback mechanism. The force feedback mechanism is configured to apply the resistance force to the movable member upon receiving the force feedback signal.

  • Patent number: 11596762
    Abstract: An improved hiatal hernia treatment enhances recovery after surgery by reducing a patient's pain at an area of treatment. The area of treatment contains a hiatal hernia and must be extensively divided before the hiatal hernia can be treated. The improved hiatal hernia treatment reduces pain through directed application of anesthetic via an applicator positioned within the area of treatment. Reduction of pain increases patient comfort reduces the need for pain medication, and lowers patient blood pressure to enhance recovery.
