  • Publication number: 20250009363
    Abstract: A surgical instrument system including an endoscope having an elongated housing extending between a proximal instrument end and a distal instrument end. The surgical instrument system may further include an irrigation sleeve having a sleeve body extending between a proximal sleeve end and a distal sleeve end. The irrigation sleeve may further have a first lumen and a second lumen spaced out of fluid communication with the first lumen, the first lumen formed in the sleeve body for receiving at least a portion of the elongated housing of the endoscope with the distal instrument end arranged adjacent to the distal sleeve end. The second lumen may be formed in the sleeve body and extend between a lumen inlet adapted for fluid communication with an irrigation source and a lumen outlet arranged to direct irrigation fluid toward the distal instrument end.

  • Patent number: 12053187
    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.

  • Patent number: 11413051
    Abstract: An irrigation sleeve, for use with a surgical system that comprises an irrigation source and a surgical tool having a tube to support a cutting accessory having a head, in turn comprises a body extending between proximal and distal ends. A first lumen formed in the body receives the tube. The head is adjacent the distal end. A second lumen formed in the body is spaced from the first lumen and comprises proximal and distal regions thereof. The proximal region of the second lumen extends from an inlet for fluid communication with the source, to a transition. The distal region of the second lumen is spaced out of fluid communication with the first lumen and extends from the transition to an outlet to direct fluid adjacent to the head.

  • Patent number: 11364036
    Abstract: A surgical saw includes a body, a coupling assembly, and a motor. The coupling assembly is mounted to the body and adapted to releasably hold a saw blade. The coupling assembly includes an anvil, a press, and a clamping assembly. The anvil has a channel or a press foot. The press has the other of the press foot and the channel. The press foot is receivable by the channel. The clamping assembly selectively moves the press and the anvil towards and away from each other. When the press is brought towards the anvil, the press foot may press a lock tooth of the saw blade into the channel so that the lock tooth is compressed between the anvil and the press to coin the lock tooth. The motor, internal to the body, is connected to the coupling assembly to reciprocate the coupling assembly and the saw blade.

  • Patent number: 10667826
    Abstract: A surgical saw and complementary blade. The blade has lock teeth that are more ductal than the cutting teeth. The saw coupling assembly has an anvil and a press. The saw coupling assembly holds the blade to the saw by compressing the saw lock teeth between the anvil and the press so as to result the coining of the lock teeth.
