A system and method are presented for treating targeted tissue using cryoablation. An introducer canula and a cryoprobe are inserted the targeted tissue. The cryoprobe is cooled and an ice ball is formed. The cryoprobe is removed while the ice ball is still frozen, and an ultrasound catheter is inserted. Ultrasound generated within the ice ball is used to determine the distance from the ultrasound catheter to a perimeter of the ice ball. This is repeated at different angles to model a slice of the ice ball. The ultrasound catheter is moved radially, and the process is repeated to create a model of at least a portion of the ice ball. The ice ball model can be displayed on a registered set of images representing the targeted tissue to ensure that the tissue lies within the treatment zone of the ice ball.

Ultrasound imaging systems for automatically identifying and saving ultrasound images relevant to a needle injection procedure, and associated systems and methods, are described herein. For example, an ultrasound imaging system includes a transducer for transmitting/receiving ultrasound signals during a needle injection procedure, and receive circuitry configured to convert the received ultrasound signals into ultrasound image data. The image data can be stored in a buffer memory. A processor can analyze the image data stored in the buffer memory to identify image data that depicts a specified injection event of the needle injection procedure, and the identified image data can be stored in a memory for archival purposes.

A surgical access assembly and method of use is disclosed. The surgical access assembly comprises an outer sheath and an obturator. The outer sheath and obturator are configured to be delivered to an area of interest within the brain. Either the outer sheath or the obturator may be configured to operate with a navigational system to track the location of either within the brain. Once positioned at a desired location, the obturator is removed, leaving a distal end of the outer sheath adjacent an area of interest, and creating a working corridor. Interrogation of the area of interest may be performed to evaluate a disorder and/or abnormality, as well as evaluate treatment regimes. Interventional devices may also be introduced to the area of interest, as well as a variety of treatments.

Methods, apparatuses, and systems for robotic insertion of a screw, a rod, or another component of a surgical implant into a patient are disclosed. Synchronous insertion of screws is performed by multiple surgical robots or a single surgical robot having multiple arms and end effectors. The movements of each robotic arm are coordinated into position in preparation of the insertion of multiple surgical implant components at the same time or in the same surgical step. The insertion of the surgical implant components is performed while monitoring the insertion progress. The insertion is completed autonomously or in coordination with a surgeon.

An ultrasonic endoscope includes: an ultrasonic transducer having an ultrasonic vibrator; a distal end portion body disposed continuously with a proximal end side of the ultrasonic transducer; an erecting base housing portion that is disposed in the distal end portion body and has an opening which opens toward one side in a direction perpendicular to the axial direction of the distal end portion body; a treatment tool lead-out port that communicates with the inside of the erecting base housing portion; an erecting base that is disposed in the inside of the erecting base housing portion and changes a lead out direction of a treatment tool led out from the treatment tool lead-out port; and a cleaning communication hole that is formed in a wall surface on a side opposite to a side where the opening of the erecting base housing portion is disposed and communicates with an outside.

Embodiments disclosed herein are directed to a non-uniform, targeted ultrasound image modification system. The system can image a target area using ultrasound and can determine one or more target locations within the target area. Further the system can determine a location and orientation of a medical device to overlay a trajectory onto the target area. A user can further modify the one or more target locations as needed. The user can then modify an image parameter for the target area, and can further modify an image parameter for one or more target locations independently of the target area. This allows a user to modify the image of the target location to suit the position, tissue structure, or a procedure taking place there without affecting the image quality of the rest of the target area, or other target locations.

A method and system may be used for tracking a medical instrument. The method may include capturing image data. The method may include capturing ultrasound data. The ultrasound data may be captured via an ultrasound probe. The method may include dewarping the image data. The method may include searching for a marker in the dewarped image data. If it is determined that the marker is found, the method may include extracting an identification. The method may include comparing fiducials with a known geometry. The method may include determining a pose. The method may include determining a location of the medical instrument relative to the ultrasound probe. The method may include overlaying a three-dimensional projection of the medical instrument onto the ultrasound data.

Provided is a paracentesis assistance system that identifies the type of biological tissue. The paracentesis assistance system (10) comprises a measurement device that applies high-frequency waves to at least two electrodes (31 and 32) of an electrode needle (3) inserted into a biological tissue (9), and repeatedly measures the electrical impedance of the biological tissue (9) where the electrode (31) is located, the electrodes being arranged at the tip of the electrode needle in a longitudinal direction; and an identification device (2) that identifies the type of biological tissue (9) based on the temporal change in the repeatedly measured electrical impedance.
