The present invention relates to an orthopedic impactor and extractor device () for an orthopaedic prosthesis (), comprising a main body (), a coupling rod () comprising a coupling end (), an activation system () in the main body (). The activation system () is associated with the coupling rod (). The coupling end () is movably guided from an active position, in which the coupling end () is coupled to the orthopaedic prosthesis (), to an inactive position, in which the coupling end () releases the orthopaedic prosthesis (); and wherein the coupling end () is movably guided in a roto-translation movement between the active position and the inactive position, and vice versa. The present invention also relates to a related orthopedic impactor and extractor kit.

Orthopedic impactor and extractor device

An orthopaedic surgical instrument, in particular a milling cutter, including: an inner rod extended along an own longitudinal axis and provided with an attachment end to a motorized member; a tubular envelope wrapping the inner rod; an operating head at a rod end which is opposite said attachment end; a gimbal joint between the rod end and a tool of said operating head such that said tool is extended along an angled axis with respect to the longitudinal axis. The milling cutter according to the invention improves the precision of execution of the positions of the holes in any surgical operation with anatomy which is difficult to get access to, such as in knee, pelvis and ankle.

Milling cutter for orthopaedic use, in particular in knee, pelvis or ankle surgery

A tibial baseplate for tibial component of a knee prosthesis including: a bulk solid portion including a proximally facing surface adapted to accommodate a bearing element for the articulation of a femoral component of the knee prosthesis; a plurality of porous portions integral with the bulk solid portion having a porous portion contacting surface opposite to the proximally facing surface adapted to contact a proximal tibia. Advantageously, the plurality of porous portions are seamlessly incorporated and embedded in the bulk solid portion.

Milling device for prosthetic surgery comprising a milling tool and a handler body. The handler body is provided with a rotating drive shaft which develops along a longitudinal axis of rotation and is connected to the milling tool to rotate the milling tool around the longitudinal axis.

Milling device for prosthetic surgery

Milling device for prosthetic surgery comprising a milling tool rotating about a milling axis, and a handling body. The handling body is provided with a drive rotating rod which develops along a longitudinal axis of linear rotation and is connected to the milling tool in order to make the milling tool rotate about the milling axis.

Guided milling device for prosthetic surgery

A method for the removal of a bone insert for a shoulder prosthesis, which provides for: forming a hole inside a proximal bone portion; inserting in the hole an operating end of an instrument provided with a moveable cutting element deep-cutting a distal base of the bone insert, by rotating the instrument through 360 degrees around its longitudinal axis; removing the instrument from the hole; inserting and fixing a pin element inside the hole; milling the bone insert; removing the bone insert and the pin element attached thereto.

Instrument for the removal of a bone insert and corresponding method

The invention relates to an orthopaedic surgical instrument () for positioning a tibial cutting guide () including: In other words, the arm () has one end () hinged to the proximal end () of the supporting rod () between a terminal stopper () and a compressing element () slidably mounted in the proximity of said proximal end () and pushed toward the proximal direction by said bistable mechanical switch () of the locking mechanism ().

Orthopaedic surgical instrument for positioning a tibial cutting guide

The present invention relates to an orthopedic surgical pliers-like tool () for performing surgery on the patella bone, comprising: &#x2014;at least a couple of jaws () coupled to corresponding handle members () pivotally mounted with a hinge bolt () in relation with one another; &#x2014;a distal clamp portions () on each jaw () for gripping and holding at least the periphery of a patella bone; &#x2014;an intermediate force transmission mechanism () between the tool handle members () and the jaws (); &#x2014;a couple of arms () in said intermediate force transmission mechanism () structurally independent from the handle members () and interposed between the handle members () and the jaws (); &#x2014;an elastic member () in each arm () for coupling each arm to a corresponding handle member () in a first linking point (); &#x2014;a second more distal linking point () in each arm () engaging a corresponding distal end () of a handle member (); &#x2014;the first linking point () of one arm () and the second linking point () of the other arm being cross linked to the same handle member ().

Orthopedic surgical pliers-like tool for holding and gripping a patella bone

The invention relates to an instrument and a corresponding surgical method for the removal of a bone insert, for example for a shoulder prosthesis. The instrument is of the type comprising:

An artificial knee joint includes a femoral component (), provided with a medial condyle (), a lateral condyle () and a front flange (). The medial condyle () and the lateral condyle () are joined together in proximity with the rear end of the intercondyle groove () by a femoral cam (), and separated by the intercondyle groove () in the remaining part of their extension. A tibial component includes a tibial plate and a tibial insert (). The tibial insert () is configured to support the medial condyle (), and the lateral condyle (), and is provided with a tibial post (). The femoral cam () is asymmetrical and comprises a distal surface () shaped like a drum which articulates with the tibial post ().
