Spinal Rod Preparation Systems and Methods
20220401131 · 2022-12-22 ·

The present disclosure provides systems and methods for preparing a spinal rod that enable the digital mapping of rod contours to produce spinal rods that conform to an ideal rod trajectory, which reduces spinal rod to screw head misalignment. Reducing spinal rod to screw head misalignment helps reduce a failure rate of spinal rods in patients. In invasive spinal fusion surgeries, a digital three-dimensional representation may be generated of a flexible rod formed to align with screws installed in the patient. In minimally invasive surgeries, a digital three-dimensional representation may be generated using pointers. A surgeon may adjust the digital three-dimensional representation via a graphical user interface. Bending instructions may be generated from the digital three-dimensional representation that direct how a spinal rod should be bent using a bending tool. The final spinal rod accounts for the anatomical environment around the screws installed in the patient.

Surgery control tool for spinal correction rod
11523849 · 2022-12-13 · ·

Disclosed is a surgery control tool: being no patient implant, including: an elongated body having the shape and the size of a spinal correction rod, end contact parts being able to contact a patient implanted spinal correction rod implant, spacers extending from the elongated body towards the end contact parts.

RATCHET ROD BENDER AND RELATED METHODS
20220387089 · 2022-12-08 ·

Implant bending instruments disclosed herein can have a plurality of bending elements that can be symmetrically driven to bend or contour an implant, such as a spinal rod. A single actuator handle can be moved to drive a compound gear train and move the bending elements to intersect an implant-receiving channel and bend an implant received therein. Instruments of the present disclosure can have an increased mechanical advantage than conventional bending instruments thereby allowing for an increased amount of force to bend an implant. A locking pawl can selectively prevent counter rotation of the gear train such that the handle can be actuated a plurality of times to achieve a desired contour angle.

Spinal plate bender
11517356 · 2022-12-06 · ·

A spinal plate bender includes an actuation assembly, a collet, and a head portion. The actuation assembly includes a housing, a lever pivotably coupled to the housing, a linkage pivotably coupled to the lever, and an actuation shaft operatively coupled with the linkage. The lever is transitionable between a neutral position and an actuated position, which imparts axial displacement to the actuation shaft. The collet includes a proximal section, a sleeve section extending distally from the proximal section, and a coupling section extending distally from the sleeve section. The head portion is configured to support a spinal plate. The head portion includes an anvil portion coupled to a distal end portion of the actuation shaft. The anvil portion is configured to engage a spinal plate to cause bending of a spinal plate supported in the head portion.

EXTRACORPOREAL BONE COMPRESSING LINK AND APPARATUS AND METHOD USING SAME
20220378478 · 2022-12-01 ·

An extracorporeal bone compressing link and apparatus and method using same. Active devices that incorporate the extracorporeal bone compressing link can transport and compress bone through external means by acting on conventional bone fasteners including but not limited pins or wires that penetrate through the skin and fixate into bone.

Laser type fixation member securement device and activation system, and related system and methods

A laser device having a proximal end and a distal end spaced from the proximal end, the distal end configured to receive a fixation member to be affixed to a target surgical site. The laser device includes a laser source supported by the laser device body and capable of emitting a laser beam to the distal end, wherein the laser source is responsive to at least one input so as to selectively switch between an inactive configuration whereby the laser source does not emit the laser beam, and an active configuration whereby the laser source emits the laser beam.

Augments, systems and methods for acetabular implants

The augments, systems and methods for supporting acetabular implants described herein can include an augment (100) for supporting an acetabular shell (90) having a first portion (136) of a locking mechanism. The system can also include a shell having a second portion of a locking mechanism (96). The first portion of the locking mechanism and the second portion of the locking mechanism can be adapted to move relative to one another from an unlocked state to a locked state to fixedly couple the augment to the shell. In some examples, the augment can be contourable to match the shape of a bone.

Facet screw system and method

A facet screw system and method includes an implant assembly having a screw with a removable head, a locking nut, and a collet. An insertion instrument is used to insert the screw, compress the facet joint, locks the implant, and breaks off the head of the screw providing a lower profile implant.

Modular spine stabilization system and associated instruments

An implantable, modular spine stabilization system that allows for multi-level treatment of the spine by providing either rigid fixation or dynamic stabilization at different levels to be treated is provided. This modular spine stabilization system may be configured to span multiple spine levels, and have a curvature that closely matches the curvature of the spine over those multiple levels to be treated. Further, the modular spine stabilization system allows adjustment of the curvature of the overall system such that the system may be adapted for a patient for a customized fit. Instruments are also provided for the assembly and/or implantation of the modular spine stabilization system. The associated instruments may include instruments for adjusting the curvature of the system to the patient, and for implanting the curved system into the patient. The instruments may be configured for implantation of the system in a minimally invasive surgery.

Tool for cutting or crimping cable in a medical procedure
11583305 · 2023-02-21 · ·

Disclosed herein is a tool for cutting or crimping a tensioned cable in a medical procedure. The tool comprises a cable forming assembly that is coupled with an inner shaft. The cable forming assembly comprises a cable former. The tool additionally comprises a central channel, which extends through the inner shaft, an outer tube within which the inner shaft is positioned, and the cable forming assembly along an entire length of each one of the inner shaft, the outer tube, and the cable forming assembly. The central channel is configured to receive and support the tensioned cable in-line with the tool. The cable former is actuatable to cut or crimp the tensioned cable when the tensioned cable passes through the central channel. Translational movement of the outer tube along the inner shaft in an engagement direction actuates the cable former to cut or crimp the tensioned cable.
