Presented herein are devices and systems as well as the methods of using the same for the purpose of reducing and/or ameliorating the sensation of pain, specifically, chronic pain. Particularly, in one aspect, the devices, systems, and their methods of use disclosed herein are effective for reducing peripheral nerve pain, such as resulting from traumatic nerve injury and other types of nerve damage.

A navigation, tracking and guiding system for the positioning of operatory instruments inside the body of a patient. The system includes a control unit, a viewer and detecting means for determining the spatial position of the viewer. The system further includes a sensor associated to an operatory instrument and insertable inside the internal portion of the body of the patient. The control unit is configured to project on the viewer an image of the state of the internal portion.

Embodiments of the technology disclosed herein is directed to a medical manipulator capable of detecting an instant when a tip of the medical manipulator is unexpectedly separated from a body tissue and thus avoid making contact with surrounding body tissues. The technology disclosed eliminates the needs for providing a force sensor located on the tip of the medical manipulator. The medical manipulator includes a movable unit at one end and an electric motor, a control unit, and an operation input unit at opposed end thereof. The movable unit includes a treating unit for treating the body tissue. The electric motor is configured to operate the movable unit. The electric motor includes a current sensor or a torque detecting unit for detecting the torque of the motor. The control unit includes a torque reducing unit for reducing the torque transmitted to the movable unit from the electric motor.

A medical instrument includes an instrument position sensor operable to generate an instrument position signal. A first head position sensor is configured to be secured in a first fixed location on or in a patient's head and generate a first head position signal. Field generating elements are configured to generate an electromagnetic field around the patient's head. A processor processes the instrument position signal to determine positioning of the patient's instrument within the electromagnetic field. The processor also processes the first head position signal to determine positioning of the patient's head within the electromagnetic field. The processor determines the position of the instrument within the patient's head based on the determined position of the patient's instrument within the electromagnetic field and based further on the determined position of the patient's head within the electromagnetic field.

Disclosed are systems and methods that provide a computerized framework for performing a decision intelligence (DI)-based assessment and/or operation of/on a patient's spine. The disclosed spinal assessment framework provides a robotically actuated screw placement and assessment system. The disclosed framework can be implemented for the performance of a preoperative, intra-operative and/or post-operative spinal assessment/procedure. The disclosed spinal framework can be utilized for robotically-actuated pedicle screw placement, robotically-actuated bone removal and/or spine construct optimization via a spinal flexibility and alignment assessment.

Various torque-limiting screwdriver devices, systems, and methods are disclosed. The screwdriver can include a body, a motor that is configured to rotate a screw engaged with the screwdriver, and a processor configured to control operation of the screwdriver. The screwdriver can have torque-limiting functionality, such as by monitoring the amount of torque applied to the screw and reducing or stopping rotation of the screw when certain torque-limiting criteria are met. In some embodiments, the screwdriver can be switched between manual operation by a user, and automated operation by a motor within the screwdriver. In some embodiments, the screwdriver can be attached to a robotic arm.

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.

Disclosed herein are suture clip delivery devices that can be loaded with several flat, disk-shaped suture clips and can deploy the suture clips one after another onto respective sutures without reloading the device with additional suture clips. An exemplary device includes a handle portion with an actuation mechanism that is coupled to a shaft portion that holds and deploys the suture clips. The shaft portion includes a mandrel on which the suture clips are mounted and a retainer that restricts the suture clips from moving proximally when the actuation mechanism pulls the mandrel proximally, which causes a distal-most suture clip to slide off the mandrel and be deployed onto one or more suture. The mandrel and remaining suture clips can them move distally to prepare to deploy the next suture clip.

The disclosed embodiments relate to systems and methods for a surgical tool or a surgical robotic system. One example method includes providing a redundant degree of freedom (DoF) for an end effector joint of one DoF by driving the joint with two actuators, calculating a position displacement of the joint to effect a desired end effector movement in response to an input command, calculating a first movement of the two actuators based on the position displacement of the joint and a second movement of the two actuators based on a second control objective in a null space corresponding to the redundant DoF, and driving the joint according to the first movement and the second movement to effect the desired end effector movement while accomplishing the second control objective in the null space.

Various torque-limiting surgical driver devices, systems, and methods are disclosed. The surgical driver can include a body, a motor that is configured to rotate a drill bit engaged with the surgical driver, and a processor configured to control operation of the surgical driver. The surgical driver can have torque-limiting functionality, such as by monitoring the amount of torque applied to a drill bit and reducing or stopping rotation of the drill bit when certain torque-limiting criteria are met.
