External fixation clamp using a trigger mechanism and stored spring energy
10702308 · 2020-07-07 · ·

An external fixation clamp for receiving a fixation element includes an inner jaw and an outer jaw movable between an open position that permits the fixation element to be placed between the inner and outer jaws and a closed position that restricts removal of the fixation element from between the inner and outer jaws. A latch assembly may cooperate with the inner and outer jaws to secure the jaws in a closed position. The latch assembly may comprise a latch and a latch biasing member. The latch may be configured to translate linearly relative to one of the inner and outer jaws, and the latch biasing member may have a first higher level of stored energy when the inner and outer jaws are in the open position and a second lower level of stored energy when the inner and outer jaws are in the closed position.

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.

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.

Laminar fixation clamp and method
10667852 · 2020-06-02 · ·

A laminar fixation clamp has a body that utilizes a clam-shell style pivot controlled by a set screw, to grasp and attach to a spine rod, while receiving a laminar fixation band that can loop around a lamina of a vertebra in order to hold the laminar fixation clamp onto the vertebra. One form comprises a two-piece structure while another form comprises a single-piece structure. In each case, an upper and lower clamping structure situated at a front of the laminar fixation clamp, is received over and onto the spine rod, while a laminar fixation band is received through clamp. The set screw controls the amount of pivoting and thus the clamping force exerted onto the spine rod.

SURGICAL PIN COMPRESSABLE WOUND DRESSING MODULE, DEVICE, AND SYSTEM
20200155198 · 2020-05-21 ·

A surgical pin compression wound dressing stabilizing system includes a compressive wound dressing module having a central orifice and radial slit, and a stabilizing device formed of a single piece of material having a longitudinal passageway and a vertical slit, the slits allowing insertion of the module and stabilizing device on a surgical pin at a wound site with the surgical pin dispose in the orifice and passageway. The stabilizing device has an upright post with the longitudinal passageway and a bottom base with a recessed central cavity open at a bottom that receives and mates with an upper portion of the module. The bottom base has a lower outer annular surface surrounding the central cavity for engaging a peripheral rib on the module to enable application of an equal distribution of a downward compressive pressure on the module.

SCHANZ SCREW WRENCH COMBINATION TOOL

A wrench device includes a proximal member including a first recess and a second recess open to the first recess. The second recess has a width smaller than the first recess. The first recess receives a first screw and the second recess receives a second screw smaller in diameter than the first screw. The device also includes a distal member coupled to the proximal member. The distal member includes a first recess, a second recess open to the first recess, and a third recess open to the second. The first recess has a width larger than a diameter of the second recess. The second recess has a diameter larger than the third recess. When the proximal and distal members are coupled, the first and second recesses of the proximal member are in open communication with the first, second and third recesses of the distal member.

20200129208 · 2020-04-30 ·

An orthopedics restoration fixation device includes: a clamping mechanism and a shock absorbing mechanism. The clamping mechanism includes: a first base; a first clamping assembly and a second clamping assembly cooperating with each other and adjustably mounted on the first base; and an adjustment assembly mounted on the first base and configured to move the first clamping assembly and the second clamping assembly towards each other or away from each other. The shock absorbing mechanism is connected to the clamping mechanism and is configured to alleviate an external impact on the clamping mechanism.

Elongated pin for an external modular fixation system for temporary and/or permanent fixation applications and external modular fixation system
10631896 · 2020-04-28 · ·

The invention relates to an elongated pin (2) for an external modular fixation system for temporary and/or permanent fixation applications to treat bone fractures and to connect two or more bone fragments to each other, comprising an elongated stem (3) extending along a longitudinal axis with a first end portion (4) and an opposite second end portion (5), said first end portion (4) having a tip for the insertion of the first end portion (4) into a bone, wherein said first end portion (4) has a conical shape with an external thread, forming a conical threaded end portion, the extension of said conical threaded end portion along the longitudinal axis being determined by the depth of penetration of the conical end portion limited to only the cortical portion of the bone.

External fixation system with radio frequency shielding

An electrical insulator is applied to a bone anchor, for instance of a bone implant, such as an external fixation frame, so as to prevent undesirable temperature increases in the bone anchor and surrounding anatomical tissue when subjected magnetic resonance imaging.
