International Classification:

A61F 2/46

US Classification:

606 86R

Abstract:

An instrument for holding a surgical tool or bone implant includes a handle with a bearing surface formed in one end for engaging the surgical tool. An elastically deformable plate is mounted on the handle body the plate having a catch element formed on a leading end thereof adapted to engage a coupling element formed on the surgical tool. The elastically deformable plate includes a cam follower formed in a recess thereon and includes a deformable spring section intermediate the can elements and the plate end with the catch element. An elongated pivotable loading member is rotatably mounted on the handle body. The loading member includes a cam surface for engaging the cam follower surface on the deformable plate. The cam surface on the loading member is shaped to elastically deform the elastically deformable plate section in a direction away from the plate catch element to thereby load and maintain a connecting force between the plate and the surgical tool or bone implant.

US Classification:

705/037000

Abstract:

A method and system for executing foreign exchange transactions anonymously via an online communications network with minimal market impact at a transparent price. An embodiment of the present invention involves a novel execution product offering two distinct services. The first is a crossing service in which buy and sell orders for each currency pair are matched directly against each other for execution at a future benchmark rate. The matching of orders and the clearing and settlement of each execution is facilitated and no market risk is undertaken. The second service is an optional residual program where, if a 100% fill on an order is desired, the customer can choose to have unmatched or residual of orders executed at the benchmark rate. Market risk associated with guaranteeing the Benchmark rate is undertaken, just as it is with the current benchmark execution process. For both services, customers pay a transparent commission.

US Classification:

606104, 623 1911

Abstract:

An insertion instrument for inserting an orthopedic implant into a bone and guiding an implant attachment element into the bone comprising: a body having a first end and a second end and a bore extending along a central axis; a fixed arm and a deflectable arm coupled to the body second end, the fixed arm spaced from the deflectable arm forming an attachment element receiving passageway therebetween extending along the central axis, the fixed arm having an implant engaging free end spaced a fixed distance from the central axis; and an actuator mounted on the first end of the body for moving the deflectable arm away from the fixed arm while allowing the attachment element to traverse the passageway.

International Classification:

A61B 17/88

US Classification:

606281, 606 86 B

Abstract:

A system for bending a surgical device is disclosed in which the system may include a bending apparatus having a housing with a series of posts received therein. In some embodiments, one of the series of posts may be selectively movable within an elongate slot in the housing, while another of the series of posts may be radially movable. Movement of the radially movable post may serve to bend a surgical device about at least one of the other remaining posts. A tool may also be provided with the system for interacting with a lever and causing the radially movable post to move radially. An alternate apparatus for bending a surgical device is also disclosed, as are methods of bending a surgical device using the aforementioned system.

Abstract:

Robotic system and methods for preparing a bone of a joint to receive an implant. Virtual object(s) are used to define a volume of material to be removed from the bone for receipt of the implant. A robotic manipulator controls a cutting tool based on the virtual object(s) to form a first cavity and a second cavity in the bone. The second cavity is formed beneath the first cavity and is rotated relative to the first cavity to define an undercut in the bone. The first and second cavities receive a body and a locking member of the implant in an unlocked position. The locking member is rotated within the second cavity to a locked position whereby the undercut engages the locking member to limit withdrawal of the implant from the bone.

International Classification:

A61B 90/00

Abstract:

A clamp assembly fixes a navigation tracker to a bone. The assembly includes first and second clamp jaws. The second clamp jaw is pivotal about a first fixed pivot. A linear driver includes a shaft. A first linkage is pivotal at one end about a second fixed pivot and coupled at an opposing end to the shaft at a first moving pivot. A second linkage is coupled at one end to the shaft at the first moving pivot and coupled at the other end to the second clamp jaw at a second moving pivot. The linear driver linearly translates the shaft to apply force to the first moving pivot in a first direction to pivot the second clamp jaw towards the first clamp jaw and in a second direction opposite to the first direction to pivot the second clamp jaw away from the first clamp jaw.

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.
