Provided are systems, devices and methods for automated steering of medical instrument in a subject's body for diagnostic and/or therapeutic purposes, wherein the steering of the medical instrument within the subject's body is based on a planned 3D trajectory and real-time updating the 3D trajectory, to allow safely and accurately reaching a target within the subject's body.

Provided are systems, devices and methods for assisting a user in positioning an automated medical device on, or in close proximity to, a body of a subject, by simulating the position and orientation of the medical device on one or more images of the subject, and providing the user with instructions regarding the actual positioning of the medical device and/or correction thereof, based on the simulated position and orientation.

Embodiments of the disclosure include a tissue and/or access device that allows for adjustability of placement of a needle for accessing a blood vessel of an individual in need thereof, particularly when used with an imaging device. The adjustability originates from both angle of the needle for insertion into the body of the individual and longitudinal placement of the needle on the body of the individual. In specific embodiments, a needle guide through which the needle traverses is detachable.

An intraoperative ultrasound imaging system and method capable of using ultrasound imaging to safely place a surgical access instrument (e.g. guide wire, dilator, cannula, etc.) through a tissue (e.g., muscle, fat, brain, liver, lung, etc.) without damaging nearby neurovascular structure is described herein. The intraoperative ultrasound system includes an ultrasound probe assembly configured for emitting and receiving ultrasound waves and a computer system including a processor and a display unit. Once the probe is in position, ultrasound imaging is performed wherein the computer receives RF data from the probe and causes a B-mode image of the visible anatomical structures (e.g. muscle, bone, etc.) to be displayed on the display unit.

The invention relates to a system for planning introduction of a needle in a patient's body, comprising: a needle guide configured to be coupled to a needle; a localization system configured for tracking the needle guide with respect to the patient's body, the localization system being coupled to a needle tracker attached to the needle guide and a reference marker adapted to be attached to the patient's body to determine a spatial position and orientation of the needle tracker relative to the reference marker; a processor configured for determining a virtual position and orientation of the needle with respect to the 3D image using localization data of the needle guide, thereby defining a virtual needle having said virtual position and orientation, detecting a part of the needle that has already been inserted into the patient's body as a trace in the 3D medical image, computing a distance between the virtual needle and the detected needle, and determining a representation of the computed distance; a display coupled to the processor for displaying a representation of the virtual needle and the representation of the computed distance between the virtual needle and the detected part of the needle.

Provided are devices and methods for anesthetizing a patient undergoing surgery, and/or pain block procedures. In certain embodiments the disclosure provides a curved cryoneurolysis needle. In some forms, the methods include inserting at least one cryoneurolysis needle into a target region of the patient, and cooling the cryo-needle to inhibit the target intercostal nerve.

A needle guide for use with a handheld probe having a connector protruding from a probe surface. The needle guide can include an upper portion including an upper surface, a lower portion defining a cavity to receive the connector of the handheld probe, and a needle channel. The needle channel can extend from a proximal portion of the upper surface to a distal end of the upper surface. The needle channel can have a fixed size. The needle guide can include a guide surface extending into the upper portion and the lower portion of the needle guide at a proximal end of the needle guide. The guide surface can include a concave shape with a conical surface that funnels into a proximal end of the needle channel.

A multi-stage dilator and cannula assembly for use in surgical procedures, including minimally invasive surgical procedures, to provide tissue dilation and opening of a portal to enable the surgeon to access and provide treatment to anatomical feature of interest.

In a handle unit for interventional procedure, a master device for interventional procedure, and a remote control interventional procedure system, the handle unit is gripped by an operator. The handle unit includes a gripper, a mode selection module and a linear motion module. The gripper is gripped by the operator. The mode selection module is equipped to the gripper, and selects one of motion modes including a linear motion mode, a rotational motion mode and a plane motion mode. The needle linearly moves with one degree of freedom in the linear motion mode. The needle rotationally moves with two degrees of freedom in the rotational motion mode. The needle moves in a plane with two degrees of freedom in the plane motion mode. The linear motion module performs the linear motion of the needle based on the selection of the mode selection module, and is equipped to the gripper.

Disclosed is an artificial intelligence-based cannula surgery diagnostic device. The device includes a cannula stroke sensing unit for sensing a stroke of a cannula generated in a surgical procedure of a patient; a surgical data processing unit for receiving surgical data generated based on a stroke of the cannula; and a surgical prognostic information-generating unit for analyzing the received surgical data based on the existing learned surgical data to generate surgical prognostic information for the patient.
