AI Technical Summary

Problems solved by technology

[0011] One of the disadvantages of known milling devices is that they are configured to shape the bone base in the direction of the milling axis, which substantially coincides with the axis of the intramedullary canal of the tibia or femur, as the case may be, and therefore cannot follow the anatomy of the tibia and femur
[0012] Sometimes, in order to avoid perforation of the cortical area, the surgeon is thus forced to fabricate a bone base of limited size, however, this may not be sufficient to guarantee adequate joint stability of the prosthesis, especially if the previously implanted prosthesis has been damaged or In any case where extended areas of cancellous bone are unavailable

Abstract

A milling device for prosthetic surgery comprises a milling tool (11) and a handler main body (14). The handler main body (14) is provided with a rotating drive shaft (22) which develops along a longitudinal axis of rotation (Z) and is connected to the milling tool (11) to rotate the milling tool (11) around the longitudinal axis (Z).

Description

technical field [0001] The present invention relates to a milling device for prosthetic surgery, suitable for preparing a base for a bone void filler, or for preparing a bone base to accommodate a prosthesis. [0002] In particular, milling equipment is particularly suitable for making bases for bone void fillers for knee prostheses, or for preparing bone bases for shoulder prostheses (also called humeral prostheses) or hip prostheses. Background technique [0003] It is well known that in orthopedic surgery for the implantation of prostheses, when it is necessary to prepare a base for a bone void filler or a shell base for a prosthesis, it is necessary to drill and / or mill the bone in order to produce a base with the desired contour. [0004] Often, in fact, congenital or traumatic degenerative conditions, such as primary arthropathy, secondary arthropathy due to trauma or infection, rheumatoid arthritis, inflammatory arthritis, osteonecrosis or bone tumors, or other simil...
