The present invention involves a surgical monitoring system and method for modeling surgical procedures. A multi-element fiducial reference pattern observable by a tracker may be transferred directly to the skin proximate the surgical site, either through a stencil as a radio-opaque ink pattern or via transfer tape, or may be applied in prepared form on a surgical incise film. Alternatively the surgical incise film may be applied over the surgical site and the inked reference pattern applied to the film before surgery. A controller determines the three-dimensional location and orientation of the surgical site by comparing the position and orientation of the reference pattern in a prior scan with the position and orientation of the reference pattern in image information about the surgical site obtained from the tracker. The system may track the movement of instruments relative to the surgical site, or may be used to track changes in the surgical site itself.

Принадлежит: Evolve Dental Technologies Inc

In an exemplary embodiment, a method of creating an impression of structures of the human oral cavity comprises: preparing impression trays: creating a first, or base, impression; grinding out portions of the base impression; and using the void(s) in the ground out base impression to take a second, or wash, impression. The base impression is taken with an excess of a high-density impression material which is positioned to extend beyond the structures of interest (of which the impression is being taken). The base impression is removed and all fine structure surrounding the structure(s) of interest is ground out. A wash impression is then taken using a low-density impression material. The base impression creates a seal around the structure(s) of interest (a closed system), thereby producing omnidirectional hydraulic pressure on the low-density material. Such omnidirectional hydraulic pressure produces a highly detailed final impression from which a high-quality model (e.g., cast) can be made.

Described herein is an anti-skid surgical instrument for use in preparing holes in bone tissue. The disclosed surgical instrument provides the ability to prepare a precise hole in bone tissue during surgery (e.g., spinal surgeries and pedicle screw placement, intramedullary screw placement). The disclosed surgical instrument accomplishes precise hole placement regardless of whether the angle between the drill axis and surface of the bone tissue is perpendicular.

DENTAL DRILL BIT SYSTEM AND METHOD

Номер: US20140127640A1
Автор: Nguyen Kim, Zacharia John
Принадлежит: ZIMMER DENTAL, INC.

A dental drill is disclosed which allows for an osteotomy to be formed in a shape which closely matches the cylindrical shape of many dental implants. In so doing, the implant engages more tissue of the resulting osteotomy, thus resulting in greater ability for the tissue to penetrate and fuse with the implant while also reducing the chances of infection and reducing the overall recovery time. In addition, by forming the dental drill with a relatively obtuse angulation between the termini of the drill flutes, the cutting forces are spread across a larger cutting area thus reducing wear on the drill itself. Moreover, by spreading the cutting force over a larger area, the heat generated by the drill is reduced and thus the discomfort afforded to the patient is reduced. 17-. (canceled)8. A method of implanting a dental implant comprising:engaging an orthopedic drill bit with tissue, including engaging a cutting tip having an apex, located at a shaft distal end and comprising an angulation of at least 125°, with the tissue;rotating the orthopedic drill bit;removing the tissue by way of one or more spiral flutes, extending from the shaft distal end, as the orthopedic drill bit is rotated;forming an orofacial cavity having a size and shape that substantially matches a portion of the drill bit; andimplanting, into at least a portion of the orofacial cavity, a dental implant having an apical end including a size or shape substantially matching the size or shape of the portion of the distal end of the dental drill bit.9.
