An implantable position detecting system is configured to detect a position of an implantable device with respect to a body structure. The system includes at least one proximity measuring transducer configured to be implanted on the body structure a distance from the implantable device, the at least one proximity measuring transducer being configured to receive energy from an external electromagnetic field generated by an external sensing interface, wherein the at least one proximity sensor is configured to emit an emitted signal responsive to the electromagnetic energy and to receive distance information comprising a sensing signal that is responsive to the distance from the implantable device.

A device is provided, including a cutting rib, the cutting rib including an arcuate portion having an outer sharp edge and a centralizer configured to receive the cutting rib through a radial slot, the radial slot forming a gap with the cutting rib. The arcuate portion of the cutting rib is formed into a profile that follows a surface of the centralizer, the outer sharp edge of the arcuate portion of the cutting rib has a wavy profile that forms a tunnel in the gap between the centralizer and the cutting rib, and the outer sharp edge of the arcuate portion of the cutting rib protrudes outwardly from the surface of the centralizer. A method for using the device to cut bone in a surgical configuration is also provided.

A rotary cutting tool including an elongated housing having a proximal end and a distal end, the elongated housing extends circumferentially around a first axis. A drive shaft disposed within the elongated housing and extending between the proximal end and the distal end and rotatable about the first axis. A cutting bit housing coupled to the distal end of the elongated housing and rotatable relative to the drive shaft about an articulation axis between a non-articulated position and one or more articulated positions. A rotary cutting bit coupled to the cutting bit housing and the drive shaft and rotatable about the articulation axis with the cutting bit housing, the rotary cutting bit and drive shaft forming a constant velocity joint.

Described herein are methods and devices useful for reaming and shaping the surfaces of a joint in a mammalian body. The reaming and shaping devices and methods are particularly useful in preparation of a joint for a minimally invasive joint replacement or resurfacing, though they may be used as part of any appropriate arthroplasty procedure.

An end effector for a computer-assisted surgical system includes a mount configured to be coupled to an arm and a housing coupled to the mount and configured to interchangeably support a first operating member and a second operating member. When the housing supports the first operating member, the housing is configured to prevent translation of the first operating member relative to the mount. When the housing supports the second operating member, the housing is configured to allow translation of the second operating member relative to the mount along a first axis.

Reciprocating rasps for the surgical preparation of the bone prior to the implantation of a glenoid or acetabular component with complex geometry are disclosed. Surgical methods for the use of such reciprocating rasps are also disclosed.

A system for cutting a bone of a patient may include a motor; a rotating shaft drivingly coupled to the motor; a support tube positioned around the rotating shaft and supporting the rotating shaft at a plurality of locations; a plurality of steering wires coupled to the support tube; and a bone cutter at a distal end of the rotating shaft.

Technologies for monitoring impaction and predicting impaction state during an orthopaedic surgical procedure include one or more impaction sensors that generate sensor data. The surgical procedure includes impaction of an orthopaedic implement such as a surgical instrument or a prosthetic component. An impaction analyzer generates an impaction state prediction with a machine learning model based on the sensor data. The impaction state prediction may include an unseated state, a seated state, and a fracture state. An impaction state user interface outputs the impaction state prediction. A model trainer may train the machine learning model with labeled sensor data.

The present invention provides an orthopaedic reamer handle that includes a reamer portion configured to transmit torque to a reamer head, a driver portion connected to the reamer portion that is configured to receive and transmit torque from a driver, and a drive train connecting the reamer portion to the driver portion to transmit torque from the driver portion to the reamer portion. The drive train includes a first drive shaft that defines a first axis and is connected to the driver portion at a first end and to a first intermediate connector at a second end. An offsetting member is connected to a second intermediate end of the first intermediate connector at an acute angle relative to the first axis and defines a second axis. The offsetting member connects to the reamer portion via a second intermediate connector at an acute angle relative to the second axis.

Method for producing a reamer such as a milling cutter intended to mill the acetabular cavity of a patient, the reamer including a rigid base with an interface for coupling to a tool holder, and including a cutter body which has a thin wall and is perforated and toothed. The rigid base is produced separately from the cutter body, by cutting out and drawing a first flat metal blank in a press.
