摘要： Systems and methods for providing a combined mosquito staging and dissection system are disclosed. The system can include a mosquito staging subsystem; a robotic pick-and-place station; and a dissection, extrusion, collection, and disposal subsystem. The subsystems can include one or more stations to provide orientation, decapitation, extrusion of salivary glands, and disposal of carcasses of the mosquitoes. The resident live sporozoites from the salivary glands can be used to produce Plasmodium SPZ-based vaccines.

摘要： A flexible manipulator apparatus includes an elongate flexible manipulator having a sensor, a user output device configured to provide sensory outputs to the user, and processing circuitry. The flexible manipulator may be movable to form a curve in the flexible manipulator. The processing circuitry may be configured to receive captured sensor data from the sensor during movement of the flexible manipulator, and determine a collision likelihood score based on application of the captured sensor data to a collision detection model used for position estimation. The collision detection model may be based on an empirical data training for the flexible manipulator that includes training sensor data from the sensor and training image data of positions of the flexible manipulator. The processing circuitry may be configured to control the user output device based on the collision likelihood score to provide a collision alert sensory output to the user.

摘要： A force-sensing tool includes a tool shaft that has a proximal end and a distal end, a flexure section attached at a first end to the distal end of the tool shaft, a tool tip operatively connected to the flexure section such that axial forces applied to the tool tip are coupled primarily to a first portion of the flexure section and transverse forces applied to the tool tip are coupled primarily to a second portion of the flexure section, an axial force sensor coupled to the first portion of the flexure section, and a transverse force sensor coupled to the second portion of the flexure section. The axial force sensor responds to axial forces applied to the tool tip substantially independently of the transverse forces applied to the tool tip under a designed operating range of forces, and the transverse force sensor responds to transverse forces applied to the tool tip substantially independently of the axial forces applied to the tool tip under the designed operating range of forces.

摘要： A micromanipulation system includes a micromanipulator that includes a handpiece, and a micromanipulation tool that includes a tool shaft and is operatively connected to the handpiece. The micromanipulator further includes an actuator assembly connected to the micromanipulation tool to provide manual control of the micromanipulation tool, and a force sensing system comprising a force sensor attached to the tool shaft. The force sensing system is configured to provide an output signal that indicates a force imposed on the tool shaft. The micromanipulation system also includes a processor that is in communication with the force sensing system, and is configured to receive the output signal and compensate for forces due to actuation of the micromanipulation tool to determine a force due to interaction of the micromanipulation tool with a region of interest. The processor outputs an indication of at least one of a magnitude and a direction of the determined force.

摘要： A surgical system provides hands-free control of at least one surgical tool includes a robot having a tool connector, a smart tool attached to the tool connector of the robot, and a feedback control system configured to communicate with the smart tool to provide feedback control of the robot. The smart tool includes a tool that has a tool shaft having a distal end and a proximal end, a strain sensor arranged at a first position along the tool shaft, at least one of a second strain sensor or a torque-force sensor arranged at a second position along the tool shaft, the second position being more towards the proximal end of the tool shaft than the first position, and a signal processor configured to communicate with the strain sensor and the at least one of the second strain sensor or the torque-force sensor to receive detection signals therefrom. The signal processor is configured to process the detection signals to determine a magnitude and position of a lateral component of a force applied to the tool shaft when the position of the applied force is between the first and second positions. The feedback system controls the robot to move in response to at least the magnitude and position of the lateral component of the force applied to the tool shaft when the position of the applied force is between the first and second positions so as to cancel the force applied to the tool shaft to thereby provide hands-free control of the at least one surgical tool.

摘要： A shape sensor system includes a deflection sensor comprising an optical fiber having at least one fiber Bragg grating (FBG) written therein and a substrate, the fiber being attached to the substrate with a selected bias distance from a neutral plane of the deflection sensor. The system further includes an optical source coupled to the fiber to provide input light to be at least partially reflected by the FBG, and an optical detection and processing system arranged to receive at least a portion of the output light and to determine a wavelength shift resulting from a change of an amount of deflection of the deflection sensor. The optical detection and processing system determines a relative amount of deflection of the deflection sensor at the FBG based on the wavelength shift. The selected bias distance is selected based on an expected range of deflection angles to be detected.
