This surgical bone preparation instrument (1) comprises a main body (5) terminated by a contacting surface (50) adapted to abut on a bone (B), and a sliding body (7) equipped with a cutting element (3) and which is movable in translation with respect to the main body (5). The bone preparation instrument (1) includes a cutting depth control ring (11) that is adjustable by a single hand, which forms an abutment surface (110) against the movement of one of the main body (5) and the sliding body (7) when the sliding body (7) reaches an adjusted cutting depth (D) corresponding to an adjustment position of the control ring (11).

An orthopedic implant kit for tightening a set screw to a head of a pedicle screw for holding a spinal rod to the pedicle screw, the kit including a screw extender for holding the head of the pedicle screw, a set screw driver for engaging with the set screw to threadably tighten the set screw to the head of the pedicle screw, a first torque limiting mechanism for limiting a torque between the set screw driver and the screw extender to a first torque value or a first torque indication mechanism for indicating that the first torque has been reached, and a second torque limiting mechanism for limiting a torque between the set screw driver and the screw extender to a second torque value, the second torque value being higher than the first torque value.

A system comprises a first robotic arm adapted to support and move a tool and a second robotic arm adapted to support and move a camera configured to capture an image of a camera field of view. The system further comprises an input device, a display, and a processor. The processor is configured to display a first synthetic image including a first synthetic image of the tool. The first synthetic image of the tool includes a portion of the tool outside of the camera field of view. The processor is also configured to receive a user input at the input device and responsive to the user input, change the display of the first synthetic image to a display of a second synthetic image including a second synthetic image of the tool that is different from the first synthetic image of the tool.

An instrument drive unit includes a housing defining a central longitudinal axis; an inertial measurement unit disposed within the housing and configured to determine a pose of the instrument drive unit; and a controller disposed within the housing, the controller configured to receive the pose of the instrument drive unit from the inertial measurement unit and to generate a corrected output signal which compensates for the pose of the instrument drive unit.

Described herein is the automatic re-registration of a bumped reference marker, where the navigation system includes the reference marker, a bump detection sensor(s), and a computing device. The computing device can store positional relationships between the reference marker, the bump detection sensor(s), and the anatomy from an initial image registration and receive position data of the reference marker and bump detection sensor(s) at times during use. The computing device can determine a delta matrix based on the stored and received information and then determine if the reference marker has been bumped. If the reference marker has been bumped the computing device can determine if automatic re-registration is required and complete the automatic re-registration if needed to correct for the bump.

A LUS robotic surgical system is trainable by a surgeon to automatically move a LUS probe in a desired fashion upon command so that the surgeon does not have to do so manually during a minimally invasive surgical procedure. A sequence of 2D ultrasound image slices captured by the LUS probe according to stored instructions are processable into a 3D ultrasound computer model of an anatomic structure, which may be displayed as a 3D or 2D overlay to a camera view or in a PIP as selected by the surgeon or programmed to assist the surgeon in inspecting an anatomic structure for abnormalities. Virtual fixtures are definable so as to assist the surgeon in accurately guiding a tool to a target on the displayed ultrasound image.

A method of operating a surgical tool includes coupling a drive housing to a tool driver of a first robotic surgical system, driving rotation of a drive shaft mounted within the drive housing and thereby commencing a firing sequence of the end effector, and setting a bailout Boolean value as “true” in an internal computer of the drive housing upon commencing the firing sequence, and storing the bailout Boolean value in a memory of the internal computer. Manually bailing out the surgical tool before completing the firing sequence, installing the surgical tool on a tool driver of a second robotic surgical system, and querying the memory of the internal computer with the second robotic surgical system and recognizing the bailout Boolean value as “true”. Initiating one or more remedial actions to ensure safe operation of the surgical tool on the second robotic surgical system.

A medical device for capturing one or more stone fragments includes a sheath having a proximal end and a distal end, a handle at the proximal end of the sheath, and a basket operable with the handle. The basket includes a plurality of wires that capture the stone fragments and has a collapsed configuration when the basket is positioned within the sheath and an expanded configuration when the basket is positioned beyond the distal end of the sheath. The medical device further includes an indicator that communicates to an operator of the medical device that the size of the stone fragments exceeds a predetermined limit and a release mechanism that releases the stone fragments from the plurality of wires when the size of the stone fragments exceeds the predetermined limit. The plurality of wires are able to reset into an operable position after releasing the stone fragments.

A drill assembly including a cutting tool slidably movable along a longitudinal axis of the drill assembly and drivable to cut an object. In an active configuration, a pressure loaded drive control assembly transfers energy from a motor to the cutting tool to drive the cutting tool. In an inactive configuration, the pressure loaded drive control assembly prevents energy transfer from the motor to the cutting tool. A biasing member of the pressure loaded drive control assembly is configured to bias the pressure loaded drive control assembly in the inactive configuration. Depressing the cutting tool against the object moves the cutting tool along the longitudinal axis and moves the pressure loaded drive control assembly to the active configuration. The biasing member returns the pressure loaded drive control assembly to the inactive configuration when the cutting tool is no longer depressed against the object.

A coupling device for coupling a rod to a bone anchor includes a receiving part having first and second ends, a central axis, and two legs defining a recess at the first end for receiving the rod, a pressure member configured to exert pressure on an inserted head, and an actuating member with an engagement surface configured to engage the pressure member. When a first portion of the actuating member moves axially in a first direction, the engagement surface is configured to move from a first axial position to a second axial position to adjust the pressure member from a non-locking position where the head is pivotable to a locking position where the head is locked. When a second portion of the actuating member moves in the first direction, the pressure member is adjusted from the locking position back to the non-locking position.
