摘要： A rongeur cutting system and method of operating said system. The rongeur cutting system may comprise a cutting unit that includes an outer tube and a cutting implement capable of both oscillation and longitudinal movement within the outer tube. The rongeur cutting system may also comprise a handpiece including a power source and spindle for actuating the cutting implement. The method of operating the rongeur cutting system may comprise operating the rongeur cutting system in a manual mode and/or operating the rongeur cutting system in a power mode. The manual mode includes moving the cutting implement longitudinally within the outer tube to manually cut tissue without utilizing the power source, and the power mode includes actuating a motor to manipulate the cutting implement within the outer tube while moving the cutting implement longitudinally within the cutting tube.

摘要： A detachable rongeur has a main body, a slider and a movable handle. A front end of the main body has a cutting edge. The movable handle is hinged to both the main body and the slider. The movable handle can drive the slider to move along first sliding grooves. A cheek portion of the main body includes a trigger lock catch structure. The movable handle can be pulled back and forth. An upper portion of the movable handle includes a first feature portion and a second feature portion that are sequentially arranged from bottom to top. The trigger lock catch structure abuts against the first feature portion or the second feature portion.

摘要： A surgical device includes a housing, a grasper assembly extending distally from the housing, a shaft extending distally from the housing, and a movable handle associated with the housing and operably coupled to the grasper assembly and the shaft. The grasper assembly includes first and second jaw members movable between an open position and a closed position. The shaft is movable relative to the grasper assembly between a retracted position and an extended position. The movable handle is associated with the housing and operably coupled to the grasper assembly and the shaft such that movement of the movable handle relative to the housing from an un-actuated position to an actuated position moves the first and second jaw members from the open position to the closed position, and moves the shaft from the retracted position to the extended position.

摘要： A collector used to collect bone includes: a container body defining an interior containment space for receiving and retaining collected bone, and having at least one open end for access and removal of collected bone from the interior containment space; and a cap in covering relation to the open end of the container body such that access to the interior containment space for removal of collected bone is inhibited. The collector includes an intake port defining an opening for receiving therein a distal end of a kerrison rongeur for collecting cut bone from a cutting area thereof, and the cap includes at least one scraper for engaging and dislodging cut bone from the cutting area of a distal end of a kerrison rongeur when received within the intake port. The collector preferably is used with a kerrison rongeur for collecting cut bone therefrom.

摘要： A disposable surgical instrument includes an instrument grip forming a receiving housing. A separate handle is mounted in the instrument grip in the manner of a rocker. A shaft tool includes a shaft having at least two relatively axially movable bar or rod components and an instrument head having patient engagement elements which can be actuated by the bar or rod components, of which one bar or rod component is fixed at the proximal end thereof to the instrument grip and the other bar or rod component has an articulation point on which the handle is directly articulated in such way that a manually actuated rocker movement of the handle about the articulation point on the handle side is transformed directly into an axial movement of the other bar or rod component on the articulation point on the shaft side.

摘要： An elastomeric sleeve which is a hollow tube having a first side, a second opposite side, a top end, and a bottom end, wherein the top end is open and the bottom end is closed. The second opposite side has a slit extending from the top end towards the bottom end. The slit and the open top end make the sleeve easy to place over the handle and to remove it from the handle. The closed bottom end facilitate the sleeves remaining on the handle during use. The slit may have an opening so that handle elements, such as leaf springs, may extend therethrough. The sleeve may have a cover for a horn member on a handle of a rongeur. The cover may have a flange at a base of the cover, thereby forming a cushion. The cover and cushion reduce or eliminate fatigue and trauma to the thenar muscles and surrounding nerves. The sleeve may also have a thumb support.

摘要： A rongeur (34) for driving a cutting unit (240) that includes an outer (240) tube and a cutting implement (302) able to both rotate in move longitudinally in the outer tube The rongeur includes a body (36) to which a rotating spindle (102) for actuating the cutting implement is mounted. The spindle is designed to allow the inner tube to while, rotating move longitudinally relative to the spindle. A mechanism (150, 180) attached to the body selectively displaces the drive inner tube so the distal end of the cutting implement can be advanced towards and retracted away from the distal end of the outer tube.

摘要： Described herein are devices and methods for fusion of adjacent vertebral bones using distractor platforms for exposure and resection of at least a portion of the facet joint, such as in performance of a TLiF procedure. In one embodiment, the distractor platform contains at least a first receptacle and/or extension adapted to couple to the implanted screw/bone marker and the method includes advancing a threaded segment of a bone fastener assembly into the identified first pedicle of the first vertebral bone, the first bone fastener assembly further comprises a second segment adapted to couple with a distraction platform adapted to concurrently attach onto at least one tissue retention blade and adapted to retain the tissue retention blade in the displaced position. Stabilization of a spinal segment is also provided by advancing a substantially concave orthopedic implant through an opening made in a posterior aspect of a disc space.
