  • Patent number: 11998677
    Abstract: A surgical fluid manager includes a pump releasably engageable to tubing and a user interface. The user interface is configured to enable finger-touch selection of a fluid flow rate through the tubing and configured to operate in at least one of a first mode or a second mode. In the first mode, the flow rate is controlled via direct selection of one of a plurality of selectable digital numeric values, while in the second mode the flow rate is controlled via user selection of one alphanumeric identifier within a scale of alphanumeric identifiers. Each respective alphanumeric identifier directly corresponds to just one instrument size within a scale of instrument sizes.

  • Patent number: 11944371
    Abstract: A bipolar electrosurgical device including an outer shaft, an inner shaft, first and second electrode surfaces, and an irrigation channel. The outer shaft defines a lumen, a proximal end and a distal end forming a cutting window. The inner shaft is rotatably disposed within the outer shaft, and defines a distal portion forming a cutting tip. The cutting tip and the cutting window combine to define a cutting implement. The first and second electrode surfaces are electrically isolated, and are formed at the cutting implement. The irrigation channel extends parallel to the outer shaft, and terminates in at least one outlet port. The outlet port is proximally spaced from the cutting window and is located radially outside of the outer shaft. Fluid (e.g., saline) is emitted at the exterior surface of the device near the cutting window and is readily present for interacting with the electrode surfaces.

  • Patent number: 11918363
    Abstract: Stimulation and recording electrode assemblies that are particularly useful for Automatic Period Stimulation (APS). Such embodiments are compatible with nerve monitoring systems to provide continuous stimulation of a nerve during surgery. Certain embodiments include an electrode assembly having cuff including a body and two ears extending from the body. Within the body, at least one electrode is supported and connected to a lead wire assembly. The ears can be brought together to enlarge a gap in the body so that the electrode assembly can be fixated around a nerve. Other embodiments include an electrode assembly including first and second needle electrodes that each have a tip. A body is provided to interconnect the needle electrodes and can be manipulated to move the tips either toward or away from one another. Disclosed embodiments provide nerve monitoring and stimulation in cases where the nerve is only partially dissected.
