A system including a tool recognition assembly comprising a first target reader with a first detection zone. The system also includes a tool configured to be installed in the tool recognition assembly, wherein the first reader detects a first reading indicating a presence or absence of the first target in the first detection zone during an installation of the tool in the tool recognition assembly, the detected first reading being at least a part of a detected insertion signature, and provides the detected insertion signature to initiate a comparison of the detected insertion signature to one or more model signatures.

Systems and methods for sensing presence of medical tools

A method for determining a position of a tool being received by a catheter, the method including capturing first images with the tool as the tool is being installed in the catheter. The method also includes generating training images for a deep convolutional neural network (DCNN) by replicating the first images and applying perturbations to the replicated first images. The method also includes training the DCNN by inputting the training images into the DCNN. The method also includes capturing second images with the tool as the tool is being installed in the catheter. The method also includes inputting the second images into the DCNN. The method also includes analyzing the second images with the trained DCNN. The method further includes determining a configuration of the tool based on the analyzed second images.

Systems and methods for detecting an orientation of medical instruments

A system may comprise a catheter including a wall having an inner surface defining a main lumen. The system may also comprise a device including an elongate flexible shaft configured to be slideably inserted within the catheter main lumen and a structure disposed around an outer surface of the elongate flexible shaft. The structure may be configured to engage with a plurality of flat surfaces comprising a portion of the inner surface to prevent rotation of the device within the main lumen.

Imaging systems and methods of use

A system comprises a tool and a catheter sized to receive the tool. The system also comprises a processor and a memory having computer readable instructions stored thereon. The computer readable instructions, when executed by the processor, cause the system to receive, via an image sensor of the tool, a plurality of images from within a lumen of the catheter. Each image comprises a plurality of pixels. For each image, a subset of the plurality of pixels associated with a viewable feature is identified. For each image, a likely orientation for the viewable feature is determined based on the identified subset of the plurality of pixels. A composite orientation for the viewable feature is determined based on a combination of the likely orientations of the viewable feature for each image. A rotational offset of the tool relative to the catheter is determined based on the determined composite orientation.

Systems and methods for orientation detection and tool installation

Systems and methods for image detection during grasping and stapling include an end effector having a first jaw and a second jaw, an imaging sensor mounted to the end effector and configured to capture images of a material graspable by the end effector, and one or more processors coupled to the end effector and the imaging sensor. The one or more processors are configured to receive the images from the imaging sensor, determine one or more properties of the material based on the images, and display the one or more properties of the material on an interface. In some embodiments, the end effector is part of a medical tool and the material is anatomical tissue. In some embodiments, the end effector further includes one or more of a stapling mechanism configured to staple the material or a cutting mechanism configured to cut the material.

System and method for image detection during instrument grasping and stapling

A system for providing on-demand functionality during a medical procedure includes an instrument, an accessory, and a mounting device attached to one or more of the instrument and the accessory. The instrument includes an instrument body and an end effector. The end effector providing a first functionality. The accessory providing a second functionality. The mounting device removably couples the accessory to the instrument to augment the first functionality with the second functionality. In one example, the end effector includes jaws to provide a surgical functionality, and the first accessory includes a camera to provide a complementary monitoring functionality. In another example, the mounting device includes a mechanical mechanism and/or a magnetic mechanism for removably coupling the accessory to the instrument.

System and method for providing on-demand functionality during a medical procedure

A quick stop device for abruptly interrupting the cutting of a workpiece by a cutter is disclosed. The quick stop device employs an outer housing connected to an inner workpiece holder by at least one shear pin. The outer housing includes an appropriate shank designed to be received in the spindle of a machine, such as a machine tool. A cutter, such as a drill bit, is mounted in a stationary position and the workpiece, mounted to the workpiece holder, is rotated during engagement with the cutter. A trigger system includes at least one spring loaded punch disposed for movement into engagement with the workpiece holder to abruptly stop rotation of the workpiece holder. This action shears the shear pin and permits continued rotation of the spindle and outer housing without substantially disturbing the chip root formed during cutting.
