Adjustable combination clamp assembly
11627991 · 2023-04-18 · ·

A bone fixation clamp includes a first clamp assembly, a second clamp assembly, an inner locking member, and an outer locking assembly. The first and second clamp assemblies are transitionable between open and closed configurations. The inner locking member is transitionable between a locked position and an unlocked position. In the locked position the inner locking member engages the first clamp assembly substantially preventing the first clamp assembly from transitioning from the closed configuration to the open configuration. The outer locking assembly is transitionable between a locked position and an unlocked position. In the locked position the outer locking assembly engages the first clamp assembly and the second clamp assembly substantially preventing both the first clamp assembly from transitioning from the closed configuration to the open configuration and the second clamp assembly from transitioning from the closed configuration to the open configuration.

Universal clamp apparatus for bone fixation device

A universal clamp apparatus for orthopedic external fixators is disclosed. Preferably, the universal clamp apparatus has two pin/rod clamps, each having seating grooves for attaching to a frame rod associated with a frame of the fixator and/or a bone pin for implantation in a bone fragment. A clamp screw extends through and connects the first and second pin/rod clamps. An ergonomically designed knob having at least one collapsible or non-collapsible turn lever acts as a torque amplifier when rotated by hand without tools to tighten and untighten the pin/rod clamps to the frame rod and/or bone pin by movement along the clamp screw. The pin/rod clamps have planar sides that are contiguous and have radial ratchet grooves that are in mating engagement and provide a ratcheting mechanism so that the rotation of the pin/rod clamps relative to each other occurs in incremental rotational steps.

A correction clamp assembly that permits a physician to surgically correct a bunion or similar deformity is provided. The assembly includes an elongate bridge, as well as first and second blocks slidably or rotatably connected to the elongate bridge. More specifically, first block is configured to slide along a slot formed in the elongate bridge, as well as rotate relative thereto. Additionally, the second block is configured to rotate relative to the elongate bridge. First and second pins may be configured to extend through the first and second block, and then into various pieces of bone. Once a cut is made in a portion of joint or bone, the pins can thereafter be moved towards and away from one another to position the respective pieces of bone in a desired location. Locking screws may also be provided to releasably secure the blocks relative to the bridge.

Adjustment assembly for external fixator assembly
09848912 · 2017-12-26 ·

An assembly for use in an external fixator, structured to adjustably interconnect at least one or a plurality of bone fixation rods to a pin clamp comprising a base structurally adapted for movable, adjustable interconnection between the pin clamp and the one or more rod clamps. An elongate support shaft is movable with the base and movably connected thereto and at least one or alternatively a plurality of rod clamps are mounted on the support shaft. Each of the plurality of one or more rod clamps is structurally adapted to secure a different fixation rod to the support shaft. The one or more rod clamps are movably connected and adjustably positioned on the support shaft in adjacent relation to one another. The base, the support shaft and one or more rod clamps are movably interconnected relative to one another to define a substantially universal disposition of said plurality of rod clamps relative to the pin clamp.

FIXATION CLAMP WITH SPACER
20230190333 · 2023-06-22 · ·

A clamping device of an external fixation system that has a jaw set with a passage at one end configured to hold an element from a first range of sizes and a second passage configured to hold an element from a different range of sizes. The jaw set includes a first jaw, a second jaw, and a slider interposed between the first and second jaws that moves to a first position when the first element is located in the first passage and to a second position when the second element is located in the second passage.

External fixator assembly

External fixator assemblies, systems, and methods thereof. An external fixator system may include a plurality of fixator assemblies configured to connect a plurality of pins, for example, positioned on opposite sides of a fractured bone, with one more rods. The fixator assemblies may include a plurality of clamp assemblies that are configured to clamp onto the rods. A distractor/compression instrument is used to adjust the location of a clamp assembly along the length of its rod.

External bone fixation system

An external fixation assembly for bone fusion or separation is disclosed. The assembly includes a fracture fusion tube, with a bracket slidably engaged thereon. The assembly further includes a collet clamp connected to the bracket, with a ball collet rotatably seated within the clamp, the ball collet having an aperture for receiving a bone bin therethrough and perforations for a compression engagement with a bone pin. The assembly uses a single screw for threadably engaging the ball collet, the clamp and the bracket such that the position of the bone pin, ball collet and bracket are all fixed.

KIRSCHNER WIRE FIXATION STRUCTURE
20170303968 · 2017-10-26 ·

A Kirschner wire fixation structure, including: at least two joint elements, each having a plurality of through-hole passages extending in different directions; and at least one connection rod; wherein the plurality of through-hole passages of the at least two joint elements are for at least two Kirschner wires and the at least one connection rod to fit through respectively, the at least two Kirschner wires are for inserting into at least one bone, and the at least one connection rod is for connecting with the at least two joint elements to form a fixation structure outside the at least one bone to stabilize and hold the at least two Kirschner wires in place.

EXTERNAL FIXATION CLAMP
20170281236 · 2017-10-05 ·

External fixing system (1) for orthopaedic exoskeleton; the fixing system (1) comprises two clamps (2, 6), which have clamping seats (5, 9) and respective knurled elements (13, 14) facing each other, and a spring (12) for pushing the clamps (2, 6) one against the other so that their relative rotation is prevented by the coupling of the two knurled elements (13, 14); in this way, in use, it is possible to obtain locking of the relative position of the clamps (2, 6) while the clamps (2, 6) are tightened by means of an Allen screw (23) arranged in an opposite position with respect to the clamping seats (5, 9).
