A rotatable surgical instrument having a protective hood with articulating bendable distal end is provided to improve and enable various orthopedic surgical procedures such as arthroscopy. The protective hood surrounds the surgical tool bit exposing only a portion of the tool bit for removing bone or soft tissue material and protects the nerve from the surgical tool bit. The protective hood can be controllably rotated from the instrument's hand piece to control the orientation of the attack angle of the surgical tool bit. Additionally, the bending of the distal end of the instrument can be controlled from the hand piece.

Method and apparatus for pre-operative planning of orthopedic surgical procedures. The pre operative planning includes the steps of image acquisition, calibration scaling and registration, fracture reduction or matching of prosthesis, application of fixation elements and creating of planning reports.

Disclosed herein is processed dermis graft for use in orthopedic surgical procedures. Specifically exemplified herein is a processed dermis graft comprising one or more bone blocks having a groove cut into the surface thereof, wherein said groove is sufficient to accommodate a fixation screw. Also disclosed is a method of processing dermis that results in a dermis derived implant suitable to replace a tendon or ligament in a recipient in need thereof. Other compositions and applications of a dermis derived implant, and methods of manufacture and use, are disclosed.

A method for generating an improved tool path for cutting a bone so as to minimize soft tissue trauma, wherein the method comprises:

accessing an image of the bone which is to be cut;

accessing an image of a pre-determined cutting pattern;

superimposing the image of the pre-determined cutting pattern against the image of the bone;

calculating the intersection of the pre-determined cutting pattern and the bone using the superimposed images of the pre-determined cutting pattern and the bone; and

generating a tool path based upon the intersection of the pre-determined cutting pattern and the bone so as to minimize soft tissue trauma by leaving a thin perimeter of bone at the boundary of the bone cut when the boundary of the bone cut is adjacent to a bone surface.

Disclosed herein is an improved Bone Tendon Bone graft for use in orthopedic surgical procedures. Specifically exemplified herein is a Bone Tendon Bone graft comprising one or more bone blocks having a groove cut into the surface thereof, wherein said groove is sufficient to accommodate a fixation screw. Also disclosed is a porcine bone tendon bone graft for use in orthopedic procedures. Additionally, Also a method of harvesting grafts that has improved efficiency, increases the quantity of extracted tissue and minimizes time required by surgeon for implantation is disclosed.

A shape and depth template for incisions with laser tips, usable in bone surgery, comprising a guiding body for a laser tip provided with two mutually opposite end faces arranged at a preset distance and a lateral surface, one of the end faces being arrangable at the laser tip incision region and with a hole that of preset shape that passes there through from one end face to the other.

A method of controlling a surgical intervention to a bone (31) comprises: obtaining a three-dimensional image or multiplanar reconstruction of the bone (31), defining a position and an axis of intervention on the three-dimensional image or multi-planar reconstruction of the bone (31), and controlling the orientation of an intervention instrument (1) equipped with an orientation sensor (2) during the surgical intervention by evaluating a signal provided by the orientation sensor (2). The method further comprises referencing the intervention instrument (1) with respect to the bone (31) before the surgical intervention by arranging the intervention instrument (1) along an anatomic landmark (32) being an edge of the bone (31) and rotating the orientation sensor (2) into a predefined position, or by arranging the intervention instrument (1) essentially perpendicular to an anatomic landmark (32) being an essentially flat surface of the bone (31) and rotating the orientation sensor (2) into a predefined position. The method according to the invention allows for efficiently achieving correct orientation and position of the intervention instrument in a bone surgical intervention. Furthermore, the method according to the invention provides an efficient real-time control at comparably low efforts. Still further, with the method according to the invention radiation exposure to the operational staff as well as patients can be reduced.

An optical tracking system includes at least one tracking array for generating and optically transmitting data between 1 and 2,000 MB/s. At least one tracker for optically receiving the optically transmitted data between 1 and 2,000 MB/s is also provided. The tracking system is used not only for tracking objects and sending tracking information quickly but also providing the user or other components in an operating room with additional data relevant to an external device such as a computer assisted device. Orthopedic surgical procedures such as total knee arthroplasty (TKA) are performed more efficiently and with better result with the optical tracking system.

A pedicle screw assembly has a retractable screw tip that facilitates the securement of the pedicle screw assembly to a spinal vertebra in a minimally invasive fashion during an orthopedic surgical procedure. The pedicle screw assembly includes a body portion including a head and a shank. The shank includes an outer surface with a thread provided thereon, an end having a cutting tip provided thereon, and a bore extending inwardly from the end and having an internally threaded region provided therein. The pedicle screw assembly also includes a tip portion including a body having a cutting edge and a shank extending from the body. The shank has an externally threaded region provided thereon that cooperates with the internally threaded region of the bore to permit movement of the tip portion relative to the body portion between extended and retracted positions.

A multi-positional dual drill guide for use in orthopedic surgical procedures provides two independent drill guides which are independently, pivotally and removably secured along a pivotal drill guide plate comprising two separate and independent guide plate sections, selectively aligning each of the two drill guides for drilling an intersecting bone channel into a common bone from different locations for the passage of a suture and associated tissue during an orthopedic repair of a joint. The drill guide provide for three dimensional movement of the drill guides to provide a range of drilling angles from nearly zero degrees up to 180-degrees apart and in a three dimensional array, the drill.

The present invention relates to a facial bone surgery apparatus for medical treatment assembled to a hand piece having a straight reciprocating part, a saline solution supply part and a foreign substance discharge part, which includes: an inner pipe reciprocally movable together the straight reciprocating means and having a hollow shape of a soft flexible material; an outer pipe connected to a main body of the hand piece and installed at an outer periphery of the inner pipe to guide reciprocal movement of the inner pipe, and having a bent section formed between both ends thereof, the outer pipe being formed of a hard material; and a cutting tool assembled at an end of the inner pipe to reciprocate therewith and reciprocally guided by the outer pipe.
