A tool comprises a distal portion and a proximal portion spaced apart by a shaft along a longitudinal axis. The distal portion includes a distal link and the proximal portion including a proximal link. The distal link and proximal link form a pair of links. The tool also comprises a set of tension load bearing members connecting the proximal link and the distal link and terminating at the links of the pair to transfer movement therebetween. The tool also comprises an articulation lock positioned between the distal portion and the proximal portion and configured to allow through passage of the set of tension load bearing members. The articulation lock is adjustable between an unlocked configuration in which the proximal and distal links are moveable and a locked configuration in which an effective length of the shaft is increased, creating a force to impede movement of the proximal and distal links.

This application is directed to a medical instrument with a hollow shaft, an actuating unit at the proximal end and an instrument tip with an instrument at the distal end, the instrument actuated via an actuating element, the element being in connection with the actuating unit and the instrument tip being pivotable relative to the shaft via a joint mechanism; the joint mechanism having pivoting members with proximal-side drive via steering wires such that movement of the proximal-side drive causes movement of the distal-side pivoting members and pivoting of the instrument tip; and a trigger mechanism with which the steering wires can be brought into a relaxed state that releases the articulation of the instrument tip. In order for the medical instrument to be cleaned and ensure that the medical instrument is safely removed even if the proximal-side drive fails, the trigger mechanism is a purely mechanical trigger mechanism.

Knuckle joint assembly for a medical device support system. The knuckle joint assembly includes a cartridge assembly that includes a cartridge housing and a rotary bearing. The cartridge housing includes a bore having a central axis and a bearing mount in the bore. The rotary bearing is press fitted in the bearing mount and configured to receive axially therethrough a spindle to rotatably support the spindle about the central axis. The knuckle joint assembly includes a retaining clip and a retaining pin. The retaining clip is selectively movable to disengage and engage a groove in a spindle to respectively support or release the spindle along a central axis. The retaining pin is movable between a first position to allow movement of the retaining clip between positions but prevent removal of the retaining clip, and a second position to block movement of the retaining clip from the engaged position.

A medical device that includes a body and an arm extending from the body and configured to receive a first device such that the first device is suspended relative to the body. Translation of the arm relative to the body is configured to move the first device relative to the body. The medical device includes a receiver extending from the body and configured to receive a second device such that the second device is suspended relative to the body.

A robotic medical system can include a motorized arm that is supported by a column of the system. The robotic arm can be operated by rotating a link of the motorized arm by actuating an actuator to drive rotation of a rotary joint. A brake can then be applied to the rotary joint to stop rotation of the link. The arm can also include an arbor that can be actuated to increase a torsional stiffness of the rotary joint.

The present disclosure provides a coupling system for coupling a medical accessory to an accessory support is provided. The present disclosure also provides a system for powering a medical accessory with an accessory support.

A retractor mounting assembly including an end-effector having a body extending between first and second faces. The first face is configured for attachment to an interface plate on the robotic arm of a surgical robot. The second face defines an arm mount. An arm extending between first and second ends with the first end configured for attachment to the end-effector arm mount and the second end providing a retractor mount configured for supportive attachment of a retractor.

An end effector arm for use with a surgical navigation system includes a base configured to attach to an end effector coupler of a surgical robot arm and a mechanical linkage. The mechanical linkage includes a first end rotatably coupled to the base and a second end opposite the first end, the second end configured to be removably coupled to a handheld surgical tool. The end effector arm further includes a spring mechanism configured to impart a variable rotational force on the mechanical linkage based on an angle of rotation of the mechanical linkage with respect to the base.

A method for performing an efficient and thorough percutaneous discectomy includes making into the patient a percutaneous incision, which is a small stab wound, no more than approximately 10 mm in length. A stimulated combination neuro-monitoring dilating probe is passed through an approximately 10 mm or less skin incision and into a patient's disc space to establish a safe path and trajectory through Kambin's Triangle. Once a neuro-monitoring dilating probe is in the disc space, a second dilator is placed over the neuro-monitoring dilating probe and impacted into the disc space. Neuro-monitoring dilating probe may then be removed. An access portal optionally combined with a force dissipation device may then be placed over the second dilator and into the disc space. The second dilator is removed and then discectomy instruments may be placed through the access portal to perform the discectomy.

A hybrid, direct-control and robotic-assisted surgical system may have a stabilizing apparatus configured to at least partially support the weight of the surgical device and having comprising a device attachment unit configured to removably receive a surgical device having an elongate shaft and a distal tip. The stabilizing apparatus can be configured to constrain movement of the device attachment unit about a remote centre of motion. A handle may be mechanically attached to the device attachment unit and manual, Cartesian movement of the handle may results in corresponding Cartesian movement of the distal tip of the surgical device. A robotic assist system may include a sensor assembly configured to monitor at least a first attribute of the handle and generate a corresponding sensor signal, a controller communicably linked to the sensor assembly to receive the sensor signal and generate a corresponding primary control signal and a powered actuation unit communicably linked to the controller to receive the primary control signal and configured to actuate an end effector of the surgical device received in the device attachment unit based on the primary control signal.
