The present teachings generally provide for a surgical system including a surgical tool configured to guide and drive a fixation device into a target anatomy of a patient along a trajectory. The surgical tool may be configured to support the fixation device along one or more portions of the length of the fixation device in order to increase accuracy and decrease bending of the fixation device during the procedure. The surgical tool may be configured to be tracked by a navigation system. The surgical instrument may be configured to be received by a surgical power tool, or may include a handle for manual use.

An example method includes administering first compressions to a chest of a subject at a first rate; identifying an electrocardiogram (ECG) of the subject; determining, by analyzing the ECG, that the subject has refibrillated; and in response to determining that the subject has refibrillated, administering second compressions to the chest of the subject at a second rate. The second rate is different than the first rate.

An example method includes charging, by a first circuit of a medical device, a capacitor by receiving a current from a single-use battery and discharging, by the first circuit of the medical device, an electrical shock to electrodes configured to be disposed on a subject. The example method further includes transmitting, by a second circuit of the medical device drawing a current from a rechargeable battery, a communication signal to an external device; and recharging, by the second circuit of the medical device, the rechargeable battery by receiving a current from a charging source.

An example system includes an external device and a monitor-defibrillator. The monitor-defibrillator may include a detection circuit configured to detect an electrical signal indicative of an electrocardiogram (ECG) of a subject, a transceiver, a display and a processor configured to determine that the display is unable to visually present the ECG. In response to determining that the display is unable to visually present the ECG, the transceiver can transmit, to the external device, an instruction to display the ECG such that the ECG is mirrored via an external display of the external device.

A patient support system and a cooling system for the same is provided. In one aspect, the patient support system may include a closed loop cooling system operable to cool a patient without significantly affecting a core body temperature of the patient.

A technique for determining a position of a marker in a coordinate system defined by medical image data is provided. The medical image data has been generated using a radiation-based medical imaging technique and is indicative of streak lines due to the marker being located in a radiation beam path. A method implementation of the technique comprises identifying streak lines in the medical image data and determining, based on the identified streak lines, a position of the marker in the coordinate system

A humeral intramedullary nail (100) may include a length extending between first and second ends (121, 122), wherein the length includes a longitudinal axis (125). The humeral intramedullary nail may also include a distal portion adjacent (123) to the first end (121), a proximal portion (124) adjacent to the second end (122), and a first oblong distal aperture (101) formed through the distal portion (123). The first distal aperture may be configured to receive a first fastening member in a first direction transverse to the longitudinal axis. The humeral intramedullary nail may further include a second distal aperture (102) formed through the distal portion (123). The second distal aperture may be closer to the first end than the first oblong distal aperture and configured to receive a second fastening member in a second direction transverse to the longitudinal axis. The humeral intramedullary nail may further include a plurality of proximal apertures (111, 112, 113, 114, 115) formed through the proximal portion (124).

The present disclosure is directed towards an adjunctive bone plate for a nail anchored within an intramedullary canal of a bone. The plate comprises a first opening configured to receive a first bone screw anchored into the bone and fixed to the nail, and a second opening configured to receive a second bone screw anchored into the bone and fixed to the nail. The second opening is configured to receive the second bone screw such that a distance between the anchored first bone screw and anchored second bone screw is variable. The plate further comprises a third opening configured to receive a third bone screw anchored into the bone and adjacent to the nail, wherein the third opening is configured to direct the third bone screw along a support direction relative to a central longitudinal axis of the third opening.

Systems, methods, and software for displaying an asymmetrical implant relative to image data representative of a patient, wherein the asymmetrical implant is configured to be attached to an implant insertion tool in one of multiple orientations. A computing device receives the image data representative of the patient, receives tracking data indicative of a pose of the patient and a pose of the implant insertion tool, and receives a model of the asymmetrical implant which includes an implant pose vector. The computing device determines an orientation of the implant pose vector relative to the image data based on the tracking data. The computing device presents a representation of the model of the asymmetrical implant relative to a representation of the implant insertion instrument based on the determined orientation of the implant pose vector.

Disclosed is a method for improving use of a medical imaging device and an optical tracking system, the method comprising: obtaining a current pose of a medical imaging device relative to an optical tracking system; obtaining a predicted movement that the medical imaging device will undergo for acquiring a medical image of a patient; determining a predicted movement path that is associated with the medical imaging device; and based on the predicted movement path, triggering display of a visualization that is configured to guide a user in repositioning the optical tracking system and the medical imaging device relative to one another such the medical imaging device can be tracked via the optical tracking system over at least a predefined minimum portion of the predicted movement path.
