The systems, instruments, and methods may receive one or more captured images of an anatomical portion of a patient; execute a surgical plan to insert the surgical tool into the anatomical portion; receive sensor data collected from one or more sensors being inserted into the anatomical portion; determine whether the sensor data corresponds to the surgical plan; and send, in response to determining that the sensor data does not correspond to the surgical plan, an alert indicating that the surgical tool is not being inserted according to the surgical plan. The one or more sensors may be attached to the surgical tool.
A61B 17/00 - Surgical instruments, devices or methods, e.g. tourniquets
A61B 90/00 - Instruments, implements or accessories specially adapted for surgery or diagnosis and not covered by any of the groups , e.g. for luxation treatment or for protecting wound edges
An instrument includes a sleeve extending between proximal and distal ends. The sleeve defines a passageway. The distal end defines an engagement portion including an engagement surface extending from a first end to a second end. A peg extends outwardly from the first end. An opening that is in communication with the passageway extends through the second end. A knob is coupled to the proximal end. A shaft includes a proximal end and an opposite distal end. The distal end of the shaft includes a mating portion. The mating portion extends through the opening. The proximal end of the shaft is coupled to the knob. The knob is rotatable relative to the sleeve to rotate the shaft relative to the sleeve. Methods of use are disclosed.
An approach is provided for delivering therapeutic materials to an intervertebral disc via a sub-ligamentous space. The approach includes positioning a tool at an interface of a longitudinal ligament and an outer surface of the intervertebral disc, in which the interface is the sub-ligamentous space. The tool may include a first needle and a second needle housed within the first needle. An insertion end of the first needle may include a shallow beveled end. The approach includes inserting the insertion end of the first needle into the sub-ligamentous space. The approach includes deploying the second needle from within the first needle into at least one of an annulus and a nucleus of the intervertebral disc. The approach includes delivering the therapeutic materials to the at least one of the annulus and the nucleus.
A method of delivering a therapeutic agent to a nucleus pulposus of an intervertebral disc is provided. The method comprises inserting a delivery tool containing the therapeutic agent through an anterior portion, a lateral portion, or an anterolateral portion of an annulus fibrosus and into the nucleus pulposus of the intervertebral disc; and delivering the therapeutic agent to the nucleus pulposus of the intervertebral disc. Devices and kits are also provided.
A spinal construct includes a body defining a transverse axis. The body includes a wall disposed between a first implant cavity and a second implant cavity. The body further defines a first opening communicating with the first implant cavity and a second opening communicating with the second implant cavity. The first opening defines a first axis and the second opening defines a second axis. At least one of the first axis and the second axis are disposed in a substantially non-perpendicular orientation relative to the transverse axis. Systems, surgical instruments, implants and methods are disclosed
A retention system includes a first member having an inner surface defining a first thread form. The first thread form includes a first stage having a first pitch and a second stage having a second pitch that is greater than the first pitch. A second member includes a shaft and a neck. The shaft includes an outer surface defining a second thread form configured to engage the first thread form to lock the second member with the first member. The neck includes a smooth unthreaded section. Methods of use are disclosed.
