  • Publication number: 20240099738
    Abstract: A cutting assembly in which an inner tube is rotatably disposed within an outer tube and defines as aspiration path. The inner tube may include segments, and the segments may define a flexible region associated with a bend of the outer tube. The outer tube may define irrigation channels, and further define irrigation apertures positioned proximal to a cutting window or distal to the flexible region. The irrigation channels fluidly separate the aspiration lumen from an irrigation path so as to prevent ingress of irrigation fluid into the aspiration lumen through slots defined by the segments. An inner jacket may be coaxially disposed within the inner tube and configured to provide a seal between the aspiration path and the irrigation path. A distal end of the inner jacket may be disposed in a counterbore, and the proximal end of the inner jacket may be proximal to the inner tube.

  • Publication number: 20230190323
    Abstract: A cutting assembly for a surgical instrument including an outer hub, an outer tube, a cutting implement, and a drive hub. A retention flange of the drive hub is arranged to retain the cutting shaft within the outer tube. The cutting assembly may include a seal, and the retention flange may contact the seal. An irrigation spacer may provide a stop of distal axial movement of the drive hub or permitting fluid to flow through irrigation passageways. The drive assembly may include an irrigation port and a suction port with a proximal end of the irrigation port may positioned axially distal to a proximal portion of the suction port. The irrigation port may be coupled to a handpiece, and the suction port may be coupled to a back cap. A handpiece may include a saddle region, recesses, and/or an apex region to facilitate ergonomic handling of the surgical instrument.

  • Publication number: 20220296254
    Abstract: A surgical handpiece system (10) includes a high-speed surgical bur assembly (102) and a surgical handpiece assembly (104). The high-speed surgical bur assembly has a nose tube (17, 106) and a driveshaft (24, 110) at least partially disposed within the nose tube. A cutting tool (18, 114) is coupled to a distal region of the driveshaft. The cutting tool and the driveshaft are configured to rotate relative to the nose tube. The surgical handpiece system comprises a hub (14, 146) and a rotatable drive chuck (30, 34, 172) for alignment and coupling to the nose tube and the driveshaft. A motor (12) is configured to rotate the rotatable drive chuck, the driveshaft, and the cutting tool when the driveshaft is coupled to the rotatable drive chuck.

  • Publication number: 20220047276
    Abstract: A surgical cutting tool for use with a handpiece having a motor is disclosed. The surgical cutting tool comprises a nose tube defining a lumen between proximal and distal ends. A bushing is coupled to the nose tube at the distal end and is disposed at least partially within the lumen. The bushing defines a second lumen configured to receive a region of a driveshaft that extends past the distal end of the nose tube. A bur defines a recess sized to receive at least a portion of the bushing within the recess. The bur is configured to be coupled to the driveshaft within the recess.

  • Publication number: 20210059859
    Abstract: Systems and methods for performing transcanal ear surgery. A volume of fluid is maintained within the ear canal to provide a flooded environment. A cutting member of a cutting instrument is submerged and operated within the flooded environment to resect tissue within the ear. A reservoir system may be coupled to the patient to facilitate providing the flooded environment. The reservoir system at least partially surrounds the auricle of the ear in fluid-tight sealing engagement with the head of the patient. An irrigation pump and a suction source on one or both of the reservoir system and the cutting instrument are operated to provide the flooded environment. The reservoir system includes an access opening sized to receive one or more surgical instruments, for example, the cutting instrument and an endoscope. The flooded environment improves cooling of the surgical site and visualization of the surgical site from the endoscope.

  • Publication number: 20170150957
    Abstract: A laparoscopic retractor (11) comprises a shaft (8) having a proximal and distal end, the distal end of the shaft being configured for adjustment from a substantially straight orientation to a curved orientation having a substantially U-shaped hook suitable for laparoscopic retraction. The proximal end of the shaft comprises a handle (1) operably connected to the distal end of the shaft for adjustment of the distal end from the substantially straight orientation to the curved orientation. The distal end of the shaft is enclosed within a flexible sheath (4) that is adapted to be inflated, and wherein a portion of the sheath covering the distal end of the shaft comprises inflatable balloon means such as one or more inflatable balloons (5) which cover the substantially U-shaped hook.
