A system for fixating a dysfunctional sacroiliac joint for SI joint fusion, the system including a sacroiliac joint implant, a sacroiliac joint screw or rod and a delivery tool configured for approaching a sacroiliac joint. The system may include an implant having a porous 3D matrix structure and may be manufactured by laser or electron beam additive manufacturing. The delivery tool may include a radiolucent material. The SI fusion system may further include custom sacroiliac joint implants, anchors, alignment tools or targeting arms manufactured for a particular patient. Pre-surgical imaging studies, including 3D rendering, and their interpretation may assist in planning desired trajectories, anchor dimensions and implant dimensions and may provide details specific to the manufacture of particular sacroiliac joint tools or implants and their implantation into the sacroiliac joint. The system may be configured for use with surgical robots and may include an integrated nerve monitoring and stimulation system.

Methods for creating a void within a bone. An elongate member is directed into a tube of an access cannula, and a handle is positioned adjacent the access cannula. A working tip and pre-bent elbow are disposed within the tube such that the pre-bent elbow is straightened. The device remains slidable relative to the access cannula. A control assembly is actuated to distally move the shaft relative to the handle. Bone adjacent the tube of the access cannula may resist the working tip from protruding from the access cannula so as to displace the handle of the device proximally, or the handle may be manually maintained adjacent the access cannula. The pre-bent elbow and the working tip are moved beyond the distal end of the tube to be freed from the constraint of the tube of the access cannula to assume a curve within the bone.

A C-arm, or a mobile intensifier device, is one example of a medical imaging device that is based on X-ray technology. Because a C-arm device can display high-resolution X-ray images in real time, a physician can monitor progress at any time during an operation, and thus can take appropriate actions based on the displayed images. Monitoring the images, however, is often challenging during certain procedures, for instance during procedures in which attention must be paid to the patient's anatomy as well as a medical imaging device display. In an example, a surgical instrument assembly includes a processor, a surgical instrument configured to operate on an anatomical structure, and a display coupled to the processor and attached to the surgical instrument. The display can be configured to display visual information comprising X-ray images generated by a medical imaging device, depth gauge information generated by a depth gauge coupled to the surgical instrument, and trajectory information associated with various intramedullary nailing operations.

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.

Disclosed is a craniotomy milling system, which includes a computer numerical milling machine having a spindle configured to be positioned relative to a craniotomy location of a cranium of a patient and an end mill. The craniotomy milling system includes a controller for controlling the feed rate of the end mill. The craniotomy milling system includes an impedance measurement system and an axial force sensor. The craniotomy milling system includes a processor electrically coupled with a controller, the impedance measurement system, and the axial force sensor. The processor is configured to send a signal to the controller to change the feed rate of the end mill in response to a change in impedance or a change in axial force.

A surgical instrument system including an endoscope having an elongated housing extending between a proximal instrument end and a distal instrument end. The surgical instrument system may further include an irrigation sleeve having a sleeve body extending between a proximal sleeve end and a distal sleeve end. The irrigation sleeve may further have a first lumen and a second lumen spaced out of fluid communication with the first lumen, the first lumen formed in the sleeve body for receiving at least a portion of the elongated housing of the endoscope with the distal instrument end arranged adjacent to the distal sleeve end. The second lumen may be formed in the sleeve body and extend between a lumen inlet adapted for fluid communication with an irrigation source and a lumen outlet arranged to direct irrigation fluid toward the distal instrument end.

A system of robotic surgery includes components capable of drilling a bore in the cranium of a patient in connection with craniotomy and other cranial surgeries. A perforator associated with such system is controlled by suitable computer-implemented instructions to maintain the perforator tip along a desired trajectory line while moving the perforator bit at locations proximal to such perforator tip in a circular motion, thereby imparting a conical oscillation to the perforator bit relative to the trajectory line. The angle at which the perforator bit is oscillated relative to such trajectory line results in the bore formed in the cranium having a diameter larger than the bit diameter, and the larger diameter and related conical oscillation is selected so as to reduce frictional force opposing withdrawal of the bit from the situs of the bore, thereby reducing the risk of jamming of the bit during its associated operations.

Devices, systems, and methods for detecting unexpected movement of a surgical instrument during a robot-assisted surgical procedure are provided. The surgical robot system may be configured to measure forces and torques experienced by the surgical instrument during the surgical procedure and determine if the forces and torques are within an acceptable range. The robot system is further configured to notify the user of the presence of the unexpected movement.

A surgical apparatus generates energy that is input onto an appliance. The appliance is one of an implant to be implanted in human or animal bone tissue by the input of the energy, and of a tool being an ultrasonic bone cutting and/or punching tool for cutting and/or punching living human or animal bone tissue by input of energy onto the implant in a surgical operation. The apparatus includes a control device and at least one handpiece, the handpiece being equipped to be held by a surgeon during the operation and to couple the energy into the appliance. The apparatus further includes a reading device equipped to read out, from an appliance data carrier, appliance data dedicated to the appliance. The control device checks, depending on the appliance data, whether the handpiece is suitable for the appliance and chooses operating parameters depending on the appliance data.

Neurophysiological instruments and techniques are improved through various enhancements. Stimulation of an instrument is possible while it is advancing into the spine or elsewhere, alerting the surgeon to the first sign the instrument or device (screw) may be too near a nerve. A directional probe helps surgeons determine the location of the hole in the pedicle. Electrically insulating sleeves prevent shunting into the soft tissues. According to a different improvement, the same probe to be used to stimulate different devices, such as screws and wires. Electrical impulses may be recorded from non-muscle regions of the body, including the spine and other portions of the central nervous system as opposed to just the extremities.
