Laser-based implant guide systems and methods that align an implant with an axis of an anatomical structure of interest are disclosed. The systems include a target base configured to couple to a patient in alignment with the axis, and a target member configured to couple to the target base that includes a visual indication of the location of the axis. The systems further include an implant guide that includes a laser device and a resection guide. The implant guide is configured to adjust at least one of the position and the orientation of the laser device with respect to the anatomical structure of interest such that a laser line projecting from the laser device is aligned with the visual indication of the target member, and the resection guide facilities implantation of the implant in a resected portion of the anatomical structure of interest in alignment with the axis.

A three dimensional magnetic sensor attached to a surgical nail is located based on an applied monotonic magnetic field gradient. Another three dimensional magnetic sensor locates a surgical drill. A display generates a real time image of the relative alignment of the surgical drill and of the surgical nail, allowing a surgeon to repair bone fractures.

An orientation sensor that includes a user input device that is configured to transition a mode of the orientation sensor and/or that includes a movable guide member. The user input device may include a button, and in response to pressing the button the mode of the orientation sensor may change (e.g., to provide inclination values of an impactor shaft when the patient is in a different position). The orientation sensor may include a display that is configured to display at least one first orientation value in a first mode and at least one second orientation value in a second mode. The orientation sensor may include an actuation member configured to actuate the movable guide member, for example, from a first position where an impactor shaft may be received in the guide to a second position where the guide may attach to the impactor shaft.

In one embodiment, an intramedullary nail has a proximal end and a distal end that are offset from one another along a distal direction. The nail has an outer surface and an inner surface. The inner surface defines a cannulation that extends into the proximal end towards the distal end. The nail defines a bone-anchor fixation hole that extends into the outer surface and entirely through the nail. The nail also defines a receptacle that is proximate to the bone-anchor fixation hole and open to the cannulation such that the receptacle is configured to receive a locator of a targeting system therein from the cannulation, where the locator includes at least one of a sensor and a field generator. The receptacle is at least partially defined by a stop that limits an insertion depth of the locator within the nail along the distal direction.

The method of treating tumors and causing full regrowth and regeneration of tissue provides for the treatment and removal of tumors through application of a static magnetic field to flesh containing a tumor, as well as quickly and effectively healing, regenerating and regrowing the tissue following treatment of the tumor. At least two magnets are positioned within a treatment region adjacent to the tumor. Flesh containing a tumor is clamped between a first annular magnet and a second annular magnet, such that the flesh is sandwiched therebetween, with each of the first and second annular magnets surrounding the tumor. Treatment of the tumor causes the tumor to become necrotic and separate from the flesh. The application of the static magnetic field is further found to effect enhanced healing, regeneration and regrowth of the tumor-free tissue.

A system for tracking a navigated instrument. The system can include a first elongated instrument and a second elongated instrument. The first elongated instrument can have a first proximal end and a first distal end. The first elongated instrument can be adapted to be positioned relative to an anatomy. The second elongated instrument can move adjacent to the first elongated instrument. The second elongated instrument can have a second proximal end and a second distal end. The system can also include at least one tracking device coupled to the second elongated instrument. When the second elongated instrument is in a first position, the at least one tracking device tracks the first distal end of the first elongated instrument, and when the second elongated instrument is in a second position, the at least one tracking device tracks the second distal end of the second elongated instrument.

A patient-specific cutting guide system comprises at least two instruments. One is a positioner configured to locate a fiducial marker on a patient's bone and to be secured in three axes. The second is a cutting guide that cooperates with the positioner and delineates cuts to be made. The instruments are designed from images of the bone with the marker already in place. Preferably, a positioner comprises at least three targeting apertures configured to locate at least three non-linear markets. The cutting guide comprises top surface contours that guide the depth of the cuts. A method of forming this system comprises placing at least one marker (preferably three) on a patient's bone, then imaging the bone, forming a positioner designed to incorporate the marker position, and forming a cutting guide configured to be oriented and anchored by the positioner.

A depth gauge device including a body extending a central longitudinal axis and including a channel and a light-passing hole, the light passing hole open to the channel, a light source mounted in the body for generating a light beam, the light beam passing through the light-passing hole toward a surface of a drill-bit extending through the channel, the light beam forming an incident light beam when reflected away from the drill-bit surface, an image sensor mounted in the body for sensing the incident light beam and generating a plurality of successive images of the drill-bit surface to detect variations in the position of the drill-bit moving through the channel and an clamp coupled to the body, the clamp including a plurality of adjustable arms configured to clamp the device to a protection sleeve.

The present invention relates to a laser assisted surgical resection alignment guide for performing joint resection surgery. The present invention includes a base plate containing a switch which activates orthogonal laser assemblies when the laser assisted surgical resection alignment guide is inserted into a surgical block. The orthogonal laser assemblies each project beams which are each refracted by lenses to project two laser lines onto a human who has been prepared for surgery.

Disclosed herein are device and methods for determining an orientation of an instrument for inserting a medical device in a bone. One such method includes simulating an insertion point and an orientation of a simulated surgical hardware installation on a diagnostic representation of the bone, and then using an electronic device to align an instrument for inserting a surgical hardware installation at a desired orientation through an insertion point of the bone by indicating when an orientation of the electronic device is within a threshold of the simulated orientation.
