Certain aspects relate to systems and techniques for articulating medical instruments. In one aspect, the instrument includes a wrist having at least two degrees of freedom of movement, and an end effector coupled to the wrist. The end effector can include an upper jaw, a lower jaw, and a firing mechanism configured to form staples in tissue. Actuation of the firing mechanism can be decoupled from the movement of the wrist in the at least two degrees of freedom.

A Robotic control system has a wand, which emits multiple narrow beams of light, which fall on a light sensor array, or with a camera, a surface, defining the wand's changing position and attitude which a computer uses to direct relative motion of robotic tools or remote processes, such as those that are controlled by a mouse, but in three dimensions and motion compensation means and means for reducing latency.

Provided is a medical video processing system capable of moderating changes in image quality of medical video resulted from encoding, and, an encoder used for the medical video system. A medical video system 1000 has a monitor group 300 and an encoder 400 that accept medical video input from a switches 100 through separate transmission paths, and the encoder 400 subjects the input medical video to encoding as well as image quality adjustment.

A robotic surgical navigation system is disclosed. An example system includes a stereoscopic camera and a robotic arm having an end-effector connected to the camera. The system also includes a navigation computer that determines a first transformation between the stereoscopic camera and a target surgical site, a second transformation between the end-effector and a robotic base of the robotic arm, and a third transformation between the robotic base and the target surgical site. The navigation computer calculates a fourth transformation using the first, second, and third transformations. The fourth transformation represents a transformation between the end-effector and the stereoscopic camera. The navigation computer uses the transformations to determine coordinates for a view vector of the stereoscopic camera that are in a coordinate system of the robotic arm, thereby enabling movement of the robotic arm based on commands provided by an operator in relation to the view vector of the camera.

The present disclosure provides systems and methods for preparing a spinal rod that enable the digital mapping of rod contours to produce spinal rods that conform to an ideal rod trajectory, which reduces spinal rod to screw head misalignment. Reducing spinal rod to screw head misalignment helps reduce a failure rate of spinal rods in patients. In invasive spinal fusion surgeries, a digital three-dimensional representation may be generated of a flexible rod formed to align with screws installed in the patient. In minimally invasive surgeries, a digital three-dimensional representation may be generated using pointers. A surgeon may adjust the digital three-dimensional representation via a graphical user interface. Bending instructions may be generated from the digital three-dimensional representation that direct how a spinal rod should be bent using a bending tool. The final spinal rod accounts for the anatomical environment around the screws installed in the patient.

A method for generating an intraoperative 3D brain model while a patient is operated. Before an opening in a patient's skull is made, the method includes: providing a preoperative 3D brain model of a patient's brain and converting it to a preoperative 3D brain point cloud; providing a preoperative 3D face model of a patient's face and converting it to a preoperative 3D face point cloud. After the opening in the patient's skull is made, the method includes: matching the intraoperative 3D face point cloud with the preoperative 3D face point cloud to find a face point transformation; transforming the intraoperative 3D brain point cloud based on said face point cloud transformation; comparing the intraoperative 3D brain point cloud with the preoperative 3D brain point cloud to determine a brain shift; and converting the preoperative 3D brain model to generate an intraoperative 3D brain model based on said brain shift.

An intubation assistance device includes an electronic controller configured to: identify, from one or more images of a patient, information about the patient including at least a diameter of a trachea and a length of an intubation pathway; determine a recommended ETT size including an ETT diameter and an ETT depth of insertion from the determined diameter of the trachea and the determined length of the intubation pathway; and display the recommended ETT size on a display device.

A method for adjusting the operation of a surgical instrument using machine learning in a surgical suite is disclosed.

A trocar is provided that is adapted to insert a lighting attachment into a body cavity. The trocar connects at its distal end to the lighting attachment such that it can be pushed into the body cavity. An endoscope may then be inserted through the trocar into the body cavity. The lighting attachment is configured to detach from the trocar and attach to the endoscope head to provide additional lighting to the endoscope. The lighting attachment includes foldable lighting panels that expand when in use in order to light a wider field of view. The lighting attachment may be powered by induction coil from the endoscope.

In an aspect, the present disclosure provides a cartridge that is pre-loaded with a surgical mesh, where the cartridge is configured to be inserted into an internal body cavity of a subject and for the surgical mesh to be deployed while the cartridge is in the internal body cavity of the subject. In another aspect, the present disclosure provides a surgical robotic system comprising a set of sensors embedded thereon, wherein the surgical robotic system is configured to perform a surgical hernia repair procedure with increased consistency.
