Technologies for monitoring impaction and predicting impaction state during an orthopaedic surgical procedure include one or more impaction sensors that generate sensor data. The surgical procedure includes impaction of an orthopaedic implement such as a surgical instrument or a prosthetic component. An impaction analyzer generates an impaction state prediction with a machine learning model based on the sensor data. The impaction state prediction may include an unseated state, a seated state, and a fracture state. An impaction state user interface outputs the impaction state prediction. A model trainer may train the machine learning model with labeled sensor data.

The present invention relates to a system and methods generally aimed at surgery. More particularly, the present invention is directed at a system and related methods for performing surgical procedures and assessments involving the use of neurophysiology.

A medical device includes an elongated sleeve having a longitudinal axis, a proximal end and a distal end. A cutting member having a plurality of sharp edges is formed from a wear-resistant ceramic material is carried at the distal end of the elongated sleeve. A motor drive is coupled to the proximal end of the elongated sleeve to rotate the sleeve at cutting member at high RPMs to cut bone and other hard tissue. An electrode is carried in a distal portion of ceramic cutting member for RF ablation of tissue when the sleeve and cutting member are is a stationary position. In methods of use, (i) the ceramic member can be engaged against bone and then rotated at high speed to cut bone tissue, and (ii) the ceramic member can be held in a stationary (non-rotating) position to engage tissue and RF energy can be delivered to the electrode to create a plasma that ablates tissue.

A method for preparing a bone of a joint of a patient includes mounting a patient-specific reference guide on a bone of a joint of a patient. A connecting portion of the reference guide is coupled to a miniaturized numerically controlled instrument having a housing including a controller, a processor and a tool driver. The patient-specific reference guide has a three-dimensional inner surface preoperatively configured to mirror and mate with a corresponding surface of a bone of a joint of a patient in only one position. The patient-specific reference guide is configured to automatically register the numerically controlled instrument to the patient's bone portion intraoperatively. The cutting tool is guided by the controlled with signals from the processor along a patient-specific tool path determined during the preoperative plan for preparing a portion of the bone.

A surgical probe and a method for forming and enlarging an access opening through a psoas muscle to provide for minimally invasive lateral approach for surgical access to a lumber intervertebral disc. A distal end portion of the probe is equipped with an electrode useful for confirming proper location of the probe and includes an inflatable dilator body for enlarging an access opening through tissue adjacent to a spinal column. The probe includes a cannula through which a K wire can be extended to anchor the probe to a patient.

A method for performing a surgical procedure on a patient using a robotic system and a navigation system. The robotic system includes a cutting tool. The navigation system has at least one locating device to track a portion of the patient during the surgical procedure. The navigation system provides information as to a position of the portion of the patient. An optical cutting guide is projected onto the portion of the patient to enable cutting of the portion of the patient with the cutting tool of the robotic system while the optical cutting guide is projected onto the portion of the patient.

An articulating drill system is provided that includes a hand-held portion and a drill portion. At least two actuators are provided for controlling at least two axes of the drill portion. A navigation system is provided to control the at least two actuators. In some embodiments, a tool is provided with the drill portion and adapted to interact with patient tissue. The drill portion can be modified to include at least two rigid objects in communication with the actuators and attached to the drill portion. The system can be used to make any linear cut within a deviation of 1.0 mm and 1.0?, or better in patient tissue.

An arthroscopic system includes a re-useable, sterilizable handle integrated with a single umbilical cable or conduit. The single umbilical cable or conduit carries electrical power from a power and/or control console to the handle for operating both a motor drive unit within the handle and delivering the RF power to a disposable RF probe or cutter which may be detachably connected to the handle. The RF power delivered to the handle and on to the probe or cutter is typically bi-polar, where the handle includes first and second electrical bi-polar contacts that couple to corresponding bi-polar electrical contacts on a hub of the disposable RF probe or cutter is connected to the handle.

A control device for controlling a surgical handpiece is suitable for controlling the surgical handpiece according to control parameters. The control device comprises local control means present on the control device, wireless communication means suitable for communicating with remote control means by a wireless communication link. The local control means and the wireless communication means is suitable for receiving instructions to adjust each control parameter. Selector means is provided for selecting either the local control means or the wireless communication means for adjusting each control parameter.

A cutting device is provided that includes a pair of cutting blades joined at a pivot point. The cutting blades are driven by an actuator to cause the cutting blades to pivot about the pivot point. The cutting device is configured to remove material underneath a surface of an implant installed on a bone during a revision arthroplasty procedure. The cutting device may travel along a length of the bone just underneath the surface of the implant to remove material and free the implant from the bone. A method for removing material underneath a surface of an implant installed on the bone is also provided. A system for removing material underneath the surface of an implant installed on the bone with the cutting device is also provided.
