  • Patent number: 10548617
    Abstract: Described herein are cannulated reamer designs and methods. In one embodiment, a reamer comprises a cannulated central body portion, a plurality of cutting legs and outer frame. The cannulated central body portion has an inner wall surface and an opposing outer wall surface defining a thickness and a bone contacting surface and an opposing distal end surface defining a length, the inner wall surface defining a bore about a central longitudinal axis of the cannulated central body portion. The plurality of cutting legs extends outwardly from the cannulated central body portion. The other defines a periphery of the reamer, the outer frame coupled to a lateral end of each of the plurality of cutting legs. The cannulated central body portion has a recess extending entirely through the thickness and only partially though the length from a location along the length above the bone contacting surface and through the opposing distal end surface.

  • Patent number: 10499929
    Abstract: Presently disclosed reamer devices include a longitudinally-extending slot formed through a cutter head portion and a portion of a shaft, thereby allowing engagement of the reamer device with a guide pin inserted into a patient's glenoid by passing the guide pin through the slot and into an interior cannula track extending longitudinally through the interior of the shaft and cutter head portion. Presently disclosed reamer devices may be configured to engage the guide pin when the cutter head portion is positioned at a location medial to the patient's humeral head. Presently disclosed systems include such reamer devices and a guide pin, such as a dual diameter guide pin having an enlarged portion and a smaller portion. Dual diameter guide pins may interact with the interior cannula track of the shaft of the reamer device to serve as a depth limit for advancement of the reamer device along the guide pin.

  • Patent number: 8801714
    Abstract: A rongeur including a stationary shaft having a length that terminates in a foot plate, a cutting slide slideably coupled with the stationary shaft and terminating in a cutting edge, a breach extending between the foot plate and the cutting edge for receiving human tissue, and handle means for slidably moving the cutting slide longitudinally relative to the shaft member. The cutting slide is provided with a pair of opposing tracking arms arranged about a distal end of the cutting slide and a third tracking arm arranged about the proximal end of the cutting slide. The tracking arms are slidably and detachably received within corresponding tracking slots in the shaft member when the rongeur is in a closed position. The tracking arms are disengaged from the tracking slots by rotating the cutting slide about a pivot axis that extends substantially parallel to the length of the shaft member thereby placing the rongeur in an open position.

  • Publication number: 20140214042
    Abstract: Various exemplary methods and devices are provided for removing abnormalities from bone. In general, the methods and devices can be used to allow excess bone to be scraped from a bone surface. In an exemplary embodiment, a scraper tool is provided that includes an elongate shaft having a plurality of blades movably disposed therein. The blades can be configured to move as a unit between a retracted configuration, in which the blades can be entirely disposed within the elongate shaft, and an advanced configuration, in which at least a portion of the blades can extend distally from the elongate shaft and/or flare away from one another. A distal portion of each of the blades can have a radius of curvature corresponding to a radius of curvature of the bone to be scraped.

  • Patent number: 8784422
    Abstract: An acetabular reaming system is disclosed of the type having a driver and a tool held together by a quick-release coupling mechanism. The tool (10) has a hollow body (12) defining a domed shape with a rotational axis (14), an apex (16) aligned with the axis (14) and a hemispherical wall (18) extending from the apex (16) to an equatorial rim (20) spaced 90 degrees from the axis (14). The rim (20) has an edge (22) visible to the user that indicates the position of the tool (10) relative to the bone. A first plurality of cutting sites (24) is arrayed along the body (12) and a second plurality of cutting sites (28) is arrayed circumferentially along the edge (22). Preferably, the first plurality of cutting sites (24) present raised first teeth (30, 130, 230, 330) having a profile selected from continuous squared (30), continuous rounded (130), discontinuous squared (230) and tongued (330) profiles.

  • Patent number: 8753344
    Abstract: A dynamic sensing method and apparatus employs microelectromechanical systems (MEMS) and nanoelectromechanical (NEMS) surgical sensors for gathering and reporting surgical parameters pertaining to a drive mechanism of a surgical device, such as speed, rotation, torque and other characteristics of the surgical device. The surgical device employs or affixes the surgical sensor on or about a surgical device for detecting electromechanical characteristics during the surgical procedure. The surgical procedure disposes the medical device in the surgical field responsive to the drive mechanism of a shaver or other endoscopic instrument inserted in a surgical field defined by the surgical procedure.

  • Publication number: 20140163559
    Abstract: Instruments and methods for preparing an intervertebral space for receiving an implant. An adjustable trial implant has an adjustable stop mechanism having a stop member connected thereto to vary the distance that a body portion of the trial implant can move into the intervertebral space. Cutting tools for forming cutouts in the adjacent vertebrae use the trial implant and/or a guide to position a cutting tool which may be a burr or a chisel. The chisel cutting tool can be moveable relative to a selected trial implant or the chisel cutting tools can be fixed onto a trial implant shaped body portion.

  • Publication number: 20140135774
    Abstract: A system for cleaning and milling bone to form bone chips. The system includes a shell into which bone stock is introduced. Internal to the shell is a cleaning element that removes soft tissue and other material surrounding the bone stock. The cleaned bone stock is transferred through an opening in the shell to a mill unit. The mill unit has a milling element against which the bone is disposed. The milling element, when actuated coverts the bone stock into bone chip. A motor drives both the cleaning element and the mill element. The shell and mill unit may be part of a head unit. The head unit is removably attached to a base in which the motor is disposed.

  • Patent number: 8702644
    Abstract: A tissue treatment device comprises a housing having a chamber that receives a treatment fluid mixture of tissue morsels and a scaffold material. A debriding shaft including a plurality of cutters is coupled with the housing. The debriding shaft extends proximally within the chamber and extends distally from the end of the housing. The debriding shaft is inserted within a treatment site such as a fistula tract and is rotated and reciprocated such that the debriding shaft removes tissue cells along the site. The site is flushed with saline or other irrigating fluid followed by application of the treatment fluid mixture. The chamber of the housing comprises agitators positioned adjacent the debriding shaft. The treatment fluid mixture passes through the chamber of the housing along and between the outer surface of the debriding shaft and the agitators for thorough mixing before exiting the device at the treatment site.
