Systems and methods for medical stapling
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.
SURGICAL SYSTEM
A surgical system includes a gripping robot that holds a treatment tool, a storage, and a controller. The storage stores relationship information of a relationship between condition information of a surgery and a position of the gripping robot. The controller sets, based on the relationship information from the storage, an initial position of the gripping robot, and generates a control signal to control the gripping robot to move to the initial position and outputs the control signal to the gripping robot.
SYSTEMS AND METHODS UTILIZING MACHINE-LEARNING FOR IN VIVO NAVIGATION
A method of providing in vivo navigation of a medical device includes: receiving input medical imaging data of a patient's anatomy; receiving input non-optical in vivo image data from a sensor on a distal end of the device in the anatomy; using a trained model to locate the distal end in the input imaging data, wherein: the model is trained, based on (i) training medical imaging data and training non-optical in vivo image data of one or more individuals' anatomy and (ii) registration data associating the training image data with locations in the training imaging data as ground truth, to learn associations between the training image data and the training imaging data; determining an output location of the medical device using the learned associations and the input data; modifying the input imaging data to depict the determined location; and causing a display to output the modified input imaging data.
SYSTEM AND METHOD FOR DETERMINING POSITION OF A STEERABLE ASSEMBLY WITHIN TISSUE OF AN ANIMAL BODY
A system and method for determining position of a steerable assembly within tissue of an animal body utilizes an elongated body structure with an implement arranged at a distal end thereof, and a premagnetized material proximate to the distal end. A signal indicative of a length of insertion of the elongated body structure into the tissue is used with a signal indicative of (i) force, strain, shape of a sensor associated with the elongated body structure and/or (ii) directionality of magnetic field applied to the premagnetized material, to determine a three-dimensional (3D) trajectory of the steerable assembly. The 3D trajectory is superimposed on a 3D model of the tissue to determine position of the steerable assembly within the tissue.
LUMINAL STRUCTURE CALCULATION APPARATUS, CREATION METHOD FOR LUMINAL STRUCTURE INFORMATION, AND NON-TRANSITORY RECORDING MEDIUM RECORDING LUMINAL STRUCTURE INFORMATION CREATION PROGRAM
A luminal structure calculation apparatus includes at least one processor including hardware. The processor acquires picked-up images at a plurality of points in time including a same site of an object acquired by an image pickup unit provided in an insertion section inserted into a lumen serving as the object and three-dimensional disposition including information concerning at least a part of a position or a direction of the image pickup unit and calculates a position of the same site based on the picked-up images at the plurality of points in time and the three-dimensional disposition to calculate a three-dimensional structure of the lumen.
SYSTEMS AND METHODS FOR REGISTERING AN INSTRUMENT TO AN IMAGE USING CHANGE IN INSTRUMENT POSITION DATA
A system may comprise a processor and a memory having computer readable instructions stored thereon. The computer readable instructions, when executed by the processor, cause the system to record position data for an instrument during an image capture period and determine an instrument position change from the recorded position data. The computer readable instructions, when executed by the processor, may also cause the system to compare the instrument position change to a position change threshold and based on the comparison, determine whether to use image data captured by an imaging system during the image capture period in a registration procedure.
Optical shape sensor, optical shape sensing console and system, and optical shape sensing method
An optical fiber (F2) having a length defining a longitudinal direction is disclosed. The optical fiber (F2) has at least two fiber cores (C21, C22) extending along the length of the optical fiber (F2), and an optical coupling member (OCM2) is arranged at a proximal optical fiber end of the optical fiber (F2). The coupling member (OCM2) has a first distal end face (OF2) optically connected to the proximal optical fiber end, and a proximal second end face (IF2) spaced apart from the first distal end face (OF2) in the longitudinal direction of the optical fiber (F2), the optical coupling member (OCM2) being configured to couple light into each of the fiber cores (C21, C22, C23).
Systems and methods of registration for image-guided procedures
A medical device includes an elongate device and one or more processors coupled to the elongate device. The elongate device includes a steerable distal end and a shape sensor located along a length of the elongate device. While the elongate device is being traversed through one or more passageways of a patient, the one or more processors are configured to, based on information from a sensor, monitor an insertion motion of the elongate device, detect a data collection event, and capture, in response to detecting the data collection event, a plurality of points along the length of the elongate device using the shape sensor. The data collection event is at least partially based on a change in direction of the insertion motion of the elongate device.
LOCKING AND DRIVE MECHANISMS FOR POSITIONING AND STABILIZATION OF CATHETERS AND ENDOSCOPIC TOOLS
A cannister system for containing a catheter, the cannister including a drive mechanism for driving the catheter from the cannister and into a luminal network of a patient, the cannister including an entrance point for insertion of a tool into the catheter.
Torque coil and method
A torque coil 10 includes an inner wire layer 14 helically wound in a constricted state. An outer wire layer 18 is helically wound over the inner wire layer in a constricted state. An outer polymer cover 20 surrounds the inner and outer layers thereby securing the inner and outer layers within the outer polymer cover.
