Devices, systems, and methods for drilling an anatomical element are provided. A drill bit may comprise a coaxial hollow shaft in communication with a plurality of apertures disposed on a surface of the drill bit. A fluid inlet may be in fluid communication with the coaxial hollow shaft via a selectively openable valve. The fluid inlet may be configured to receive pressurized fluid. When the valve is opened, the pressurized fluid may be released into the coaxial hollow shaft, and when at least one of the plurality of apertures is not blocked, the pressurized fluid may be released through the at least one aperture of the plurality of apertures.

Medical devices and related methods for transforming bone, other tissue, or other material are disclosed herein. According to an aspect, a cutting device includes a static casing that defines a sheathing slot and an opening. The sheathing slot extends to the opening and has a first height at an end of the opening. Further, the bone cutting device includes a horn including a first end and a second end. The first end is configured to operatively connect to a source of movement. Further, the second end includes a cutting component having a second height. The first height is greater than the second height.

Aspects of the present disclosure relate to systems for performing a surgical procedure using a power tool or power instrument with systems, devices and/or control units for adjusting, regulating, interrupting, and/or restoring electric current to the power tool or instrument during operation, for example, when the power tool or instrument is at a predetermined distance to a boundary of a safe zone or a target volume of operation.

Embodiments of bone and tissue resection devices are disclosed herein. In one embodiment, a device can include a blade having a distal cutting edge configured to perform a cutting action that produces a plug or core from a media being cut by the cutting edge, a drive mechanism arranged to transfer an oscillating force to the cutting edge for oscillating the cutting edge, a shield positioned to block contact with a portion of the cutting edge, and a depth adjustment mechanism configured to translate the cutting edge along a proximal-distal axis of the shield to adjust an axial position of the cutting edge relative to the shield.

A tool for surgically removing tissue of a patient includes a body, a flexible rotating shaft that drives a distal cutting tool and is drivingly coupled to a motor supported by bearings in a flexible tubular sheath to allow the shaft to rotate and be shifted longitudinally. Steering cables in the sheath control the flexion of the sheath. A processor controls the operation to ensure that the cutting tool operates within a predetermined resection area, controlling a combination of motor speed, sheath flexion, and shaft retraction to assist surgery in the resection area.

A bone, cartilage, and disk removal tool assembly is provided with a motor mounted in a housing. A spindle is mounted for rotation to the housing. A rack-and-pinion mechanism is operably driven by the motor and connected to the spindle to oscillate the spindle for providing a rotary oscillating cutting operation. According to at least another embodiment, a plurality of cams is supported in the housing and driven for rotation by the motor. A plurality of followers is mounted for rotation to the housing, in engagement with the plurality of cams so that one rotation of the plurality of cams oscillates the plurality of followers more than once while preventing over-rotation of the plurality of followers. A peak angular acceleration of the spindle is less than nine million radians per second squared.

A surgical device includes a plurality of cameras integrated therein. The view of each of the plurality of cameras can be integrated together. A surgical tool that includes an integrated camera may be used in conjunction with the surgical device. The image produced by the camera integrated with the surgical tool may be associated with the images generated by the plurality of cameras integrated in the surgical device. The position and orientation of the cameras and/or the surgical tool can be tracked, and the surgical tool can be rendered as at least partially transparent. A surgical device may be powered by a hydraulic system, thereby reducing electromagnetic interference with tracking devices.

A medical device includes an elongated sleeve having a longitudinal axis, a proximal end and a distal end. A cutting member extends distally from the distal end of the elongated sleeve and has sharp cutting edges. The cutting head is formed from a wear-resistant ceramic material, and a motor coupled to the proximal end of elongated sleeve rotate the cutting member. The cutter is engaged against bone and rotated to cut bone tissue without leaving any foreign particles in the site.

A surgical device includes a plurality of cameras integrated therein. The view of each of the plurality of cameras can be integrated together to provide a composite image. A surgical tool that includes an integrated camera may be used in conjunction with the surgical device. The image produced by the camera integrated with the surgical tool may be associated with the composite image generated by the plurality of cameras integrated in the surgical device. The position and orientation of the cameras and/or the surgical tool can be tracked, and the surgical tool can be rendered as transparent on the composite image. A surgical device may be powered by a hydraulic system, thereby reducing electromagnetic interference with tracking devices.
