Abstract: Implementations described herein include a bone cement mixing and delivery device including a cylindrical container defines a chamber and has an injection passage disposed at the distal end thereof. A plug can be removably disposable in the injection passage. The mixing screw is rotatably disposable in the chamber and has a screw thread extending along an outer surface of the mixing screw as well as a return passage extending through the mixing screw from the proximal end to the distal end thereof. In a mixing mode of the device, a mixing rod engages and rotates the mixing screw about the longitudinal axis of the cylindrical container causing material disposed in the chamber to be moved distally and return to the proximal end of the chamber through the return passage of the mixing screw. In an injection mode of the device, the plug can be removed from the injection passage and an injection rod occludes the return passage of the mixing screw.

Abstract: A method of inserting an electrode into a cranial cavity of a cranium can include determining a length, between a target within the cranial cavity and a proximal end of a multipiece cannula, of the electrode for insertion of the electrode to the target. A distal end of the electrode can be inserted through a multipiece cannula supported by an instrument holder of a surgical arm. The surgical arm can be positioned such that a distance from the target to the proximal end of the cannula is equal to the length. The electrode can be fed through the cannula and through the anchor bolt into the cranial cavity. Feeding of the electrode through the cannula and into the cranial cavity can be stopped when the length of the electrode fed into the cavity reaches the length between the proximal opening of the multipiece cannula and the target.

Abstract: A method for making a rapid prototype of a patient's mouth to be used in the design and fabrication of a dental prosthesis. The method takes an impression of a mouth including a first installation site having a dental implant installed in the first installation site and a gingival healing abutment having at least one informational marker attached to the dental implant. A stone model is prepared based on the impression, including teeth models and model markers indicative of the at least one informational marker. The model is scanned. Scan data is generated from the scanning. The scan data is transferred to a CAD program. A three-dimensional model of the installation site is created in the CAD program. The at least one informational marker is determined to gather information for manufacturing the rapid protocol. Rapid prototype dimensional information is developed.
