According to one embodiment of the present disclosure, a surgical device is disclosed. The surgical device includes a motor and a transmission assembly movable by the motor. The surgical device also includes a force sensor configured to measure force imparted on the transmission assembly. The device may also include a controller configured to: control the motor to move the transmission assembly to a starting position, interrogate the force sensor to receive a sensor signal, compare the sensor signal to a threshold, and determine whether the force sensor is faulty based on the comparison of the sensor signal to the threshold.

A surgical instrument includes a motor-driven drive shaft, a distal firing rod coupled to a driven element of a surgical end effector, and a clutch mechanism coupled between the drive shaft and the distal firing rod. The clutch mechanism is configured to electrically connect the drive shaft and the distal firing rod upon the distal firing rod experiencing a threshold force. The electrical connection signals a processor that the threshold force has been exceeded.

In a particular implementation, an apparatus configured to measure bone temperature during drilling includes a processor and an infrared (IR) sensor coupled to the processor and configured to measure temperature data indicating a temperature at an interface between a drill bit and a bone of a patient.

Navigation assistance systems and methods for use with a surgical instrument to assist in navigation of a surgical instrument during an operation. The system may include sensors that may observe the patient to generate positioning data regarding the relative position of the surgical instrument and the patient. The system may retrieve imaging data regarding the patient and correlate the imaging data to the positioning data. In turn, the position of the surgical instrument relative to the imaging data may be provided and used to generate navigation date (e.g., position, orientation, trajectory, or the like) regarding the surgical instrument.

An example method includes obtaining, a virtual model of a portion of an anatomy of a patient obtained from a virtual surgical plan for an orthopedic joint repair surgical procedure to attach a prosthetic to the anatomy; identifying, based on data obtained by one or more sensors, positions of one or more physical markers positioned relative to the anatomy of the patient; and registering, based on the identified positions, the virtual model of the portion of the anatomy with a corresponding observed portion of the anatomy.

A torque detection vascular therapy system employing a vascular therapy device (101) and a torque detection controller (130). The vascular therapy device (101) is operable to be transitioned from a pre-deployed state to a post-deployed state, and includes a matrix of imageable markers representative of a geometry of the vascular therapy device (101). The torque detection controller (130) controls a detection of a non-torsional deployment or a torsional deployment of the vascular therapy device (101) subsequent to a transition of the vascular therapy device (101) from the pre-deployed state to the post-deployed state by deriving a vector indication of the non-torsional deployment or the torsional deployment of the vascular therapy device (101) from a matrix orientation similarity or a matrix orientation dissimilarity between a baseline device geometry of the vascular therapy device (101) represented by the matrix of the imageable markers and an imaged device geometry of the vascular therapy device (101) represented by the matrix of imageable markers.

A catheter system for treating a treatment site within or adjacent to a vessel wall or a heart valve includes an energy source, a balloon, an energy guide, and an electrical analyzer assembly. The energy source generates energy. The balloon is positionable substantially adjacent to the treatment site. The balloon has a balloon wall that defines a balloon interior that receives a balloon fluid. The energy guide is configured to receive energy from the energy source and guide the energy into the balloon interior. The electrical analyzer assembly is configured to monitor a balloon condition during use of the catheter system. The electrical analyzer assembly can include a first electrode, a second electrode, and an impedance detector that is electrically coupled to the first electrode and the second electrode. The impedance detector is configured to detect impedance between the first electrode and the second electrode.

A method of verifying torque measurements of a reaction torque transducer of an instrument drive unit includes a controller receiving a verification signal, generating an acceptable range of torques, receiving a torque signal, comparing the torque signal to the acceptable range of torques, and stopping a motor if the torque applied by the motor is outside of the acceptable range of torques. The verification signal is indicative of the current drawn by the motor and the torque signal is indicative of torque applied by the motor.

A device sized and shaped for insertion into a body comprising: at least one mechanical limb comprising: a support segment; a first flexible section extending from the support segment and terminating in a coupling section; and a second flexible section extending from the coupling section and terminating in a tool or a connector for a tool; wherein a long axis of one or more of the flexible sections is bendable in a single bending plane; wherein a long axis length of the first flexible section is at least double a maximum extent of the first flexible section perpendicular to a flexible section long axis; wherein a long axis length of the second flexible section is at least double a maximum extent of the second flexible section perpendicular to a flexible section long axis.

In an energy treatment system, a processor temporally detects an electrical property value of an ultrasonic transducer, holds a temporary peak value of the electrical property value, detects an impedance value between the probe electrode and the jaw electrode, and compares the electrical property value and the temporary peak value to determine whether a predetermined condition is satisfied, and whether the impedance value exceeds a predetermined threshold. In response to determining that the electric property value satisfies the predetermined condition and the impedance value is larger than the predetermined threshold, the processor performs at least one of: (i) stopping and (ii) decreasing output from the first power supply, and notifying the determination result.
