A method of providing a channel in nervous tissue filled with an aqueous gel for implantation of a microelectrode or other medical device lacking sufficient physical stability for direct implantation by insertion, comprises providing an apparatus comprising an oblong rigid pin covered by a dry gel forming agent; locating a target in the tissue; defining a straight insertion path a desired tissue insertion point and the target; aligning the pin with its end foremost with the insertion path; inserting the pin into the tissue to a position near or at the target; allowing sufficient time to pass for a gel to be formed around the pin, withdrawing the pin. Also disclosed is a corresponding channel; a method of implantation of a microelectrode or microprobe into nervous tissue via the channel; a corresponding method of implantation of living cells; a corresponding apparatus for forming the channel.

The disclosure relates to an end effector of a surgical robot, and more particularly to an end effector of a surgical robot, which can rapidly and conveniently perform a surgical operation by the robot, thereby not only safely carrying out a surgical process but also easily and accurately gripping a surgical tool during the surgical operation and setting and keeping a location of the surgical tool and a surgical site.

The end effector of the surgical robot according to the disclosure, as an end effector mounted on a surgical robot, includes: a force/torque sensor module mounted to a robot arm; an end effector frame to which the force/torque sensor module is coupled; a clamping unit installed in the end effector frame; and a tool mounting unit detachably coupled to the end effector frame by the clamping unit and supporting a surgical tool.

A medical instrument positioning tracking system according to the present invention comprises: a bar-type medical instrument of which the front end part is formed in a bar shape including needle and syringe shapes and which has an identification segment formed, on the rear end part thereof, in the longitudinal direction of the bar shape; a tracking multi-camera including a plurality of cameras provided at a plurality of locations so that the identification segment can be photographed in a plurality of time points; a display device for displaying an augmented reality image with the bar-type medical instrument as an augmented object and also displaying relevant information including location and angle information of the bar-type medical instrument; and a control device for acquiring, in real time, a tracking image capture by the tracking multi-camera for every frame, estimating a three-dimensional segment by using the acquired image, estimating the actual three-dimensional positioning of the bar-type medical instrument by using the location relationship between a pre-measured location of the bar-type medical instrument and the three-dimensional segment, and displaying, as an augmented reality image, the estimated three-dimensional positioning information including the location and angle information of the bar-type medical instrument on the display device.

A teleoperational medical system for performing a medical procedure in a surgical field includes a dynamic guided setup system having step-by-step setup instructions for setting up a teleoperational assembly having at least one motorized surgical arm configured to assist in a surgical procedure. It also includes a user interface configured to communicate the step-by-step setup instructions to a user. The dynamic guided setup system is configured to automatically recognize completion of a first setup step based on detected physical arrangement of at least one surgical arm on a teleoperational assembly and automatically display a prompt for a subsequent setup step after the recognizing completion of the first setup step.
