Orthopedic implants, systems, instruments, and methods. A bi-portal lumbar interbody fusion system may include an expandable interbody implant and minimally invasive pedicle-based intradiscal fixation implants. The interbody and intradiscal implants may be installed with intelligent instrumentation capable of repeatably providing precision placement of the implants. The bi-portal system may be robotically-enabled to guide the instruments and implants along desired access trajectories to the surgical area.

Systems and methods may display an indication of an impact force from a driving device. A method may include displaying the indication of the impact force with a light. The light may be located on the driving device, a component attached to the driving device, a user interface, or the like. Different colors may be used to indicate different impact forces. For example, a first light color may correspond to an impact force below a first threshold, a second light color may correspond to an impact force above a second threshold, and a third light color may correspond to an impact force between the thresholds. The impact force may be detected using a sensor, which may output a voltage to cause the illumination.

An orthopedic assembly is described that comprises an orthopedic device, an anchor, and a locking mechanism. The orthopedic device can be a plate member having an aperture that is configured to receive the anchor. The anchor can include a head, neck and shank portion. The head portion can include a plurality of arms separated by grooves that are capable of splaying. The assembly is configured such that when the locking mechanism is inserted into the head portion, this causes expansion of the arms of the head. This expansion locks and secures the anchor to the orthopedic device. Various instruments are provided that can deliver the locking mechanism to the anchor, and can provide impact to lock functionality.

A method for performing an efficient and thorough percutaneous discectomy includes making into the patient a percutaneous incision, which is a small stab wound, no more than approximately 10 mm in length. A stimulated combination neuro-monitoring dilating probe is passed through an approximately 10 mm or less skin incision and into a patient's disc space to establish a safe path and trajectory through Kambin's Triangle. Once a neuro-monitoring dilating probe is in the disc space, a second dilator is placed over the neuro-monitoring dilating probe and impacted into the disc space. Neuro-monitoring dilating probe may then be removed. An access portal optionally combined with a force dissipation device may then be placed over the second dilator and into the disc space. The second dilator is removed and then discectomy instruments may be placed through the access portal to perform the discectomy.

A method of ankle replacement includes forming an anterior cut in a bone and forming a stem hole in a distal end of the bone. The stem hole is formed using a plurality of broaches positioned against the distal end of the bone through the anterior cut. A first portion and a second portion of a stem implant are inserted into the stem hole through the anterior cut in the bone. The first portion is coupled to the second portion using a coupling device inserted through the anterior cut in the bone. The stem implant is impacted into the stem hole using an offset impactor.

Various exemplary surgical impacting tool interfaces and methods of using surgical impacting tool interfaces are provided. In general, a surgical impacting tool includes a locking assembly configured to releasably attach to an adapter. In response to engagement with the adapter, the locking assembly is configured to move from an unlocked configuration, in which the adapter is not releasably attached to the surgical impacting tool (nor is any other adapter releasably attached to the surgical impacting tool via the locking assembly), to a locked configuration, in which the adapter is releasably attached to the surgical impacting tool via the locking assembly. The locking assembly is configured to receive the adapter in a longitudinal direction along a longitudinal axis defined by the locking assembly and to automatically lock the adapter to the surgical impacting tool.

In general, data modules for surgical instruments and methods of using data modules for surgical instruments are provided. In an exemplary embodiment, a data module is configured to be removably attached to a powered surgical tool such as an electrosurgical tool. The data module is a standalone device including electronic components that are configured to, with the data module attached to the electrosurgical tool, interact with the electrosurgical tool.

A fixing device and an installation tool and a fixing method of the cranial flap, wherein the installation tool comprises a driving part, a loading part and an over torque protection mechanism disposed between the driving part and the loading part, the driving part drives the loading part to rotate by the over torque protection mechanism, the loading part is used for tightening the cranial flap fixation device, when the torque of the driving part acting on the over torque protection mechanism is larger than the threshold value, the over torque protection mechanism will be separated from the driving part and/or the loading part. The present invention not only effectively improves the installation and disassembly efficiency of the installation tool, but also eliminates hidden safety hazards caused by uncertainties caused by human factors in the tightening process, significantly improves the safety of the installation process.

A minimally invasive hip arthroplasty technique involves intramedullary insertion of an elongate femoral broach into a femur. The broach has a superior lateromedial transverse bore. A reaming rod is then located through the transverse bore and the neck of the femur. A cutting head is coupled to a distal end of the reaming rod via an incision. An orthogonal drive arm of an arthroplasty jig may also be inserted behind the cutting head to press the cutting head to ream the acetabulum while the reaming rod rotates the cutting head.
