Sternal closure cerclage, plate implant and instrumentation
A system including a bone punch tool and a needle guide. The bone punch tool can include a support arm having a support arm proximal portion and a support arm distal portion, a pivot arm having a pivot arm proximal portion and a pivot arm distal portion, and an arcuate punch configured to punch through bone. The pivot arm distal portion can be pivotably coupled to the support arm distal portion, such that the pivot arm proximal portion is configured to be moved away from the support arm proximal portion to extend the arcuate punch into a punch position to punch an arcuate hole through bone. The needle guide can be configured to guide a needle through the arcuate hole.
GUILLOTINE STYLE CUTTING MECHANISM
A guillotine style cutting mechanism that can cut material without a pair of pivoting blades that are externally exposed, does not require a user to open and close two fingers to operate, and can be operated in both the left and right hands (not designed for either hand). The cutting mechanism includes a receiving inlet (trap) for receiving the material, a stationary blade within the trap and a moveable blade that enters the trap when activated by an engagement mechanism. The cutting mechanism may include an outer housing having an open interior, an extension arm extending from the housing to create the trap, a stationary blade within the trap, a movable blade formed on a rod within the housing, and an engagement button that causes the moveable blade to traverse the housing so as to extend into the trap and engage the stationary blade to cut the material.
METHOD OF OPERATING A RONGEUR FOR CUTTING AND REMOVING TISSUE
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.
SURGICAL RONGEUR AND METHODS THEREOF
A surgical rongeur includes a lower shaft that defines a floor including a trap door, the lower shaft terminates in a static footplate. An upper shaft is slidably coupled to a top surface of the lower shaft, the upper shaft terminates in a cutting blade. An elongated member is slidably coupled along the floor of the lower shaft and terminates in a sliding footplate. A primary trigger is coupled to the upper shaft, where actuation of the primary trigger is configured to alternately move the cutting blade between an open position and a closed position. A secondary trigger is coupled to the elongated member, where actuation of the secondary trigger, while the cutting blade is in the closed position, is configured to retract the sliding footplate from the static footplate into one of a plurality of positions.
Bone and tissue resection devices and methods
Embodiments of bone and tissue resection devices are disclosed herein. In one embodiment, a device can include a stationary assembly having a housing, an elongated sleeve extending distally from the housing, and a cutting region disposed distal to the sleeve. The device can further include a drive assembly having a blade shaft extending through the elongated sleeve, the blade shaft having a distal tip with a cutting surface configured to extend into the cutting region when the drive assembly advances distally relative to the stationary assembly. The drive assembly can further include an oscillator coupled to the blade shaft and configured to engage with a source of continuous rotational motion to convert the continuous rotational motion into oscillating motion of the drive shaft. Further, the drive assembly can be configured to slidably couple to the stationary assembly to permit selective translation of the drive assembly relative to the stationary assembly.
Arthroscopic devices and methods
A tissue treatment device has a shaft assembly including an outer sleeve and an inner sleeve. The inner sleeve is co-axially and rotatably received in an axial passageway in the outer sleeve. A dielectric housing has an outer cutting window forming a distal portion of the outer sleeve, and a distal portion of the inner sleeve forms an RF electrode and has an inner cutting window formed therein. The outer and inner cutting windows have outer and inner cutting edges disposed to close together as the inner sleeve is rotated relative to the outer sleeve.
Push button rongeur
Disclosed is a Rongeur for surgical use. The disclosed Rongeur has a push button actuator which, upon activation, allows the long parts of the Rongeur to be easily separated for thorough cleaning and sterilization for reuse.
SURGICAL VISUALIZATION SYSTEMS
A surgical retractor includes a plurality of cameras integrated therein. One such retractor includes a tubular retractor and an insert supporting said plurality of cameras can be disposed within a tubular retractor.
Intervertebral Disc Implants And Tooling
A kit for preparing an intervertebral disc space for receiving an implant (100) includes a plurality of trials (152) having different sizes. Each trial (152) includes a body (154) insertible into an intervertebral disc space, the body (154) having a leading end (162), a trailing end (164), a top surface (156) and a bottom surface (160), the top surface of the body having a first groove (176) formed therein. Each implant also includes a flange (166) secured to the trailing end (164) of the body (154), the flange (166) having a first channel (180) aligned with the first groove (176), wherein each of the different sized trials has a different flange thickness. The flange thickness controls advancement of a cutting tool such as a chisel (192) into the first groove at the top surface of the trial body, which controls the depth of the cut into vertebral bone.
