The invention relates to a surgical tool (1) for cutting a helical groove in a bone with a body (2) receiving at least a portion of a drive shaft (9) and a tool part (3) held on same comprising a functional element (5) that produces the groove in the bone by oscillating. The tool part (3) comprises a projecting, rotatable shaft (4) at whose end opposite the body (2) the pin (5) constituting the functional element extends through an aperture (8) out of the shaft (4) that, in order to remove material of the bone, can oscillate longitudinally. The shaft (4) is coupled in such a way with the drive shaft (9) that the latter exerts torque on the shaft (4) and the pin (5) at least indirectly, at least one wing (6) projecting radially from the shaft (4) that extends at a spacing beginning behind the pin (5) in the peripheral direction of the shaft (4) helically in the direction of the body (2). The drive shaft (9) has an eccentric pin (11) projecting from its front-side end that is in engagement with a vibratory shaft (7) extending through the shaft (4), the pin (5) being firmly held on the vibratory shaft (7).

Provided is a drilling device for acromioplasty including an outer tube assembly including including a head section having a rotor having a first power transmission unit having a hollow structure and configured to receive power and a twist drill coupled to a lower end of the rotor with a hollow structure and provided with a suction port formed on an outer circumferential surface thereof, and an outer tube having a tubular shape and having one end to which the head section is coupled, an inner tube assembly including an inner tube having a hollow structure and rotatably inserted into the outer tube assembly, a second power transmission unit having a hollow structure and formed at one end of the inner tube to transmit power to the first power transmission unit, a rotation transmission unit formed at the other end of the inner tube and configured to receive a rotational force from the outside, and a discharge section disposed between the rotation transmission unit and the inner tube to discharge ground bone wastes to the outside, and a connecting pipe configured to connect the twist drill and the inner tube such that the ground bone wastes is discharged to the outside.

Disclosed are devices and methods for creating a bore in bone. The devices and methods described involve driving a rotating bit in an axial direction such that both rotation and linear movement are controlled and measurable. The instrument is useful for a surgeon to control and simultaneously measure the travel of the tool into the bone and prevent injury to surrounding structures.

A tool for use with a surgical robotic manipulator that comprises an energy applicator including a shaft extending along an axis between a proximal end and a distal end. The shaft has a retention surface and an ejection surface. A tool assembly comprises a support structure to support the energy applicator and an axial connector assembly arranged to engage and releasably lock the energy applicator to the support structure in a locked state via the retention surface. The tool assembly is also configured to apply an ejection force to the energy applicator to provide a tactile indication to the user that the energy applicator is not fully engaged by the axial connector assembly if a suitable force is not provided by the user to overcome the ejection force and place the energy applicator in the locked state.

Aspects of the disclosure relate to surgical cutting systems having a surgical tool and a powered hand piece. The surgical tool can include a cutting tool having a coupling portion for selective connection to a drive pin of the hand piece. The coupling portion defines a tang that is configured to promote self-alignment of the cutting tool and the drive pin during connection of the cutting tool and the hand piece, thus promoting ease of use.

A surgical system includes a surgical robot with an end effector that supports a drive assembly, a manual interface, and a trigger assembly. A cutting tool is attached to the drive assembly and rotatable about a cutting axis. A method includes positioning, with the surgical robot, the cutting tool relative to a surgical site to align the cutting axis with a predetermined trajectory. A user engages the trigger assembly for rotating the cutting tool about the cutting axis with the drive assembly and advancing the cutting tool along the predetermined trajectory at the surgical site to a first depth. A user applies force to the manual interface for rotating the cutting tool about the cutting axis and advancing the cutting tool along the predetermined trajectory to a second depth greater than the first depth.

An angled instrument assembly includes an angled sleeve, a driver shaft, and a tool bit. The angled sleeve includes a straight passage segment that meets an angled passage segment at a junction. The junction includes an inner elbow and an outer elbow. Material is removed from the inner surface of the inner elbow in order to improve the ease with which the driver shaft can be moved in and out of the angled sleeve. The assembly can also include drafted female or male engagement bodies for facilitating the engagement and disengagement of the tool bit with a tool bit engagement assembly located at the distal end of the driver shaft.

A drill bit comprising a cutting portion having an edge for penetrating bone and a resilient tine configured to be inserted into a drill housing, the resilient tine including a tab having an abutment surface configured to establish a snap-fit connection with a drill gear within the drill housing, and wherein the drill bit is capable of being removed from the drill housing by disengaging the abutment surface from the drill gear.

An articulating drill system is provided that includes a hand-held portion and a drill portion. At least two actuators are provided for controlling at least two axes of the drill portion. A navigation system is provided to control the at least two actuators. In some embodiments, a tool is provided with the drill portion and adapted to interact with patient tissue. The drill portion can be modified to include at least two rigid objects in communication with the actuators and attached to the drill portion. The system can be used to make any linear cut within a deviation of 1.0 mm and 1.0?, or better in patient tissue.
