Abstract:
A knife and sheath assembly includes a knife having a handle and a blade and a sheath having a cavity for releasably receiving the knife blade in a storage condition. A first end portion of the blade is adjustably mounted in the handle and a second end portion including a cutting edge protrudes from the handle. The blade is movable between a first, retracted position in which a first length of the blade protrudes from the handle and a second, extended position in which a second length of the blade longer than the first length protrudes from the handle. A releasable latch member on the handle releasably locks the knife blade in the first and second positions, and the sheath cavity is designed to receive the portion of the knife blade which protrudes from the handle in the retracted position, such that the overall length of the assembly is reduced when the knife is sheathed.

Abstract:
A pulsed irrigation handpiece comprises a pulsed irrigation liquid outlet for applying liquid pulses to a surgical site, a pump unit reciprocatingly driveable for pumping pulses of irrigation liquid through the outlet, an electric powered drive unit for reciprocatingly driving the pump unit, and a housing containing the pump and drive units. A irrigation inlet hose leads from the pump unit out of the handpiece housing and is connectable to a remote irrigation liquid source. An irrigation inlet hose adjacent the remote end thereof and electric conductors extending along the irrigation inlet hose transfer electric power from the supply unit to the drive unit in the handpiece. Removable tips are alternatively removably attachable to the irrigation liquid outlet adjacent the front end of the handpiece.

Abstract:
A medical/surgical irrigating handpiece with both a discharge line through which fluid is applied to the site and a suction line through which the discharge fluid is drawn away. The handpiece has a variable speed pulse pump. A single, variable-speed motor actuates the pump to regulate the pumping rate. Power to actuate the motor comes from a battery pack that remote to the handpiece. A control mechanism attached to the handpiece regulates the energization signal applied to the motor so as to regulate motor speed.

International Classification:
B01F 7/20 B01F 13/06
US Classification:
366189, 366139, 366195, 366308
Abstract:
A bone cement mixing and delivery system is provided in which separate components of bone cement are mixed together in a mixer to form a bone cement mixture. The mixer includes a mixing paddle and a mixing shaft connected to the mixing paddle. A motor operatively engages the mixing shaft to rotate the mixing shaft and the mixing paddle to mix the components in a mixing chamber. The motor also operatively engages a transfer mechanism. After a predetermined mixing period has elapsed, the motor automatically actuates the transfer mechanism to transfer the mixture to a delivery device. The mixture is then delivered to a target site, such as a vertebral body of a patient or other anatomical site.
Shock-Resistant And Environmentally Sealed Container

International Classification:
B65D 45/22
US Classification:
220326, 292113, 292247
Abstract:
A shock-resistant and environmentally sealed container comprising a first section and a second section. A latching system for the container comprises a deflectable pin coupled to the first section of the container with a latch coupled to the second section. The latch includes a deflectable pin engaging member. When the deflectable pin engaging member is engaged with the deflectable pin, the deflectable pin absorbs relative movement between the first section and the second section of the container. Another embodiment of the container employs a latch containing a deflectable member. The latch is pivotally coupled to a latch pin that is mounted to either the first section or the second section of the container. The deflectable member is positioned between the latch pin and the latch, and the deflectable member is configured to absorb relative movement between the first section and the second section.
Motorized Bone Cement Mixing And Delivery System That Automatically Transfers Bone Cement Between The Mixer And The Delivery Device And That Automatically Terminates The Mixing And Transfer Processes

US Classification:
366189, 366139, 366195, 366308
Abstract:
A bone cement mixing and delivery system is provided in which separate components of bone cement are mixed together in a mixer to form a bone cement mixture. The mixer includes a paddle for mixing the components in a mixing chamber and a piston that pushes the mixing cement into an attached delivery device. The system further includes a switch that disconnects the drive assembly that actuates the paddle and piston from its power source. The switch is automatically tripped by a follower that moves upon actuation of the drive assembly. Once the cement is mixed and transferred to the delivery device, the follower trips the switch to automatically deactivate the drive assembly.
Systems And Methods For Vertebral Disc Replacement

Synergy Disc Replacement, Inc. - London, Ontario
International Classification:
A61F 2/44
US Classification:
623 1716, 623 1711
Abstract:
Methods and instrumentation for implantation of an intervertebral disc prosthesis are provided. A guide tool with sagittal and coronal reference features guides placement of guide pins relative to a sagittal plane and a coronal plane of the vertebrae. A retainer lockable to the guide pins has a ratcheting mechanism providing distraction or compression. A rasp, planer or other tools may be aligned to the retainer and inserted into the intervertebral space to prepare the vertebral endplates. An interoperatively adjustable trial is alignable to the retainer and measures an angularity of the intervertebral space. A prosthesis with keying features may be mounted to a prosthesis inserter with complementary features, held by pivotable arms and compressed between prongs. The inserter may be aligned to the retainer and advanced to implant the prosthesis in the intervertebral space. A prosthesis remover may grip one prosthetic end plate and extract the entire prosthesis.
