A system for determining an orientation of a tool axis with respect to a coordinate frame of a robot is described herein. The robot includes a tool holder and a plurality of fiducial markers for defining a first coordinate frame of the robot. A calibration device is provided having a second fiducial marker for a tracking system to track positions and configured to couple to the tool holder; and rotate relative to the tool holder when coupled to the tool holder. A computer having a processor is configured to fit a circle or arc to recorded positions of the calibration device. The recorded positions of the calibration device are recorded when coupled to the tool holder, is rotated relative to the tool holder. A vector normal to the fitted circle or arc is calculated to determine an orientation of the tool axis. A method of use is also provided.

Constant-torque intraosseous access devices and methods thereof are disclosed. An intraosseous access device can include a constant-torque spring assembly disposed in a housing, a drive shaft extending from the housing, and an intraosseous needle coupled to the drive shaft configured to provide intraosseous access to a medullary cavity of a patient. A method of such an intraosseous access device can include inserting a distal end of the intraosseous needle through skin at an insertion site of a patient; applying force to bone at the insertion site with the distal end of the intraosseous needle, which starts winding a metal ribbon of the constant-torque spring assembly from an output spool onto a storage spool, thereby starting rotation of the intraosseous needle; and drilling through the bone until the intraosseous needle enters a medullary cavity of the patient, thereby achieving intraosseous access with the intraosseous access device.

A hand-held electromechanical surgical device is configured to selectively connect with a surgical accessory. The surgical device includes a power-pack, an outer shell housing, and a gasket. The power-pack is configured to selectively control a surgical accessory. The outer shell housing includes a distal half-section and a proximal half-section, the distal half-section and the proximal half-section together defining a cavity configured to selectively encase substantially the entire power-pack therein. The gasket is located between the distal half-section and the proximal half-section of the outer shell housing. The gasket is configured to create a seal between the distal half-section and the proximal half-section and to provide a sterile barrier between the power-pack and an outside environment outside the outer shell housing.

A medical power tool includes a motor, a first drive transmission part drive-transmitted from the motor, a second drive transmission part drive-transmitted from the first drive transmission part in a non-contact manner, a tool holding part holding a tool drive-transmitted from the second drive transmission part, a tool body having heat resistance, which is assembled so as to cover the first drive transmission part and the second drive transmission part, and the tool detachably mounted to the tool holding part and provided to protrude at a tip side in a longitudinal direction of the tool body.

An anchor inserter including an inserter tube extending along a longitudinal axis having a proximal inserter end and a distal inserter end. The inserter also includes an inserter tip attached to and extending distally from the distal inserter end. The inserter tip has a proximal tip end and a distal tip end with a suture anchor retention slot extending through the distal tip end. The inserter has one or more cutting edges extending at least a partially along an outer perimeter edge of the distal tip end. The distal tip end has a first arm and a second arm. The first arm is substantially straight and the second arm is curved.

A surgical instrument including a tool, a handpiece, and a locking member. The handpiece includes both a coupling member configured to cooperate with the tool, and a driver for rotating the tool. The locking member is movable from an unlocked position to a locked position in response to centrifugal force generated during rotation of the locking member. The locking member is configured to secure the tool to the handpiece when in the locked position.

The present invention comprises a device and system for delivering implantable bodies for anchoring human tissue and bony anatomy. The system may comprise a housing with a handle, an advancement mechanism, a hollow shaft, and a plurality of implant bodies. The present invention also describes a fixation device, such as a dart, staple, screw, or rivet so that the housing includes a handle comprising a lever or trigger for advancing implants, and optionally comprising a second lever or trigger for a second operation. The surgical device may also include an impacting mechanism and a manual advancing mechanism for advancing an elongated body into and through bone, with an optionally reverse setting which changes the direction to retract the elongated body. The invention further includes methods for using the surgical device.

Device and method for reaming bone. In exemplary embodiments, the device may comprise a shaft configured to be rotated about a long axis thereof. The device also may comprise a plurality of cutting members connected to a distal end region of the shaft, rotationally offset from one another about the long axis, and forming a portion of an expandable cutting head. The device further may comprise an inner member configured to be moved with respect to the shaft to change a diameter of the cutting head. In exemplary methods, the device may be utilized to ream a medullary cavity while being pushed or pulled along the medullary cavity.

The present disclosure provides a burr hole cover (e.g., burr hole cover) and method of manufacturing such apparatus. The burr hole cover disclosed herein may be multi-functional in that it may be used to: (a) form a burr hole which provides access to the brain, and (b) facilitate concealing the burr hole without employing any fastening devices (e.g., surgical screws, wires, etc.). In embodiments, the burr hole cover may include a sleeve having an outer surface, an inner surface, and a hollowed portion. In embodiments, the outer surface of the sleeve may define external serrations. The sleeve may be configured to create a burr hole in a skull, and the external serrations may be configured to secure the sleeve within the burr hole. The burr hole cover may also include a plate configured to fit with the sleeve and conceal the burr hole.

A spinal implant comprises a proximal member including a body having a first diameter and a head having a second diameter. The body includes an outer surface disposed for non-fixation with a superior facet of a vertebra, and the second diameter being greater than the first diameter. The spinal implant comprises a distal member having a third diameter and being configured for fixation with an inferior facet of an adjacent vertebra. Systems, surgical instruments and methods are disclosed.
