Description
Technical field
The invention belongs to medical material technical fields, be related to artificial femur's prosthese, and in particular to a kind of with fossa trochanterica
Titanium medical femoral joint.
Background technique
Femur is maximum long bone in human body, can be divided into integrated both ends.Towards interior top, end, which is expanded, is in for upper end
Spherical shape is femoral head, with acetabular bone associated section.The center of head slightly below, has one small recessed, is called fovea of head of femur, is ligament of head of femur
Attachment at.The thinner part in outer lower side of head claims neck of femur.The angle of neck and body claims collodiaphyseal angle, and male is 132 ° average, women
It is 127 ° average.There is a upward protuberance in the outside of neck body intersection, is called greater trochanter, and the interior lesser protuberance in lower section is called small
Rotor.The medial surface of greater trochanter has a recess to be known as fossa trochanterica (being called Pyriform sinus).It is preceding to have intertrochanteric line between large and small rotor, after
There is crista ntertrochanterica to be connected.Claim femoral intertrochanteric between the two, is the multiple place of fracture.Femur is human body longest, most solid long bone,
Its length accounts for about the 1/4 of height.
For medical femoral joint due to the particularity of material, product structure, technique is different, current organic add-on type,
There is wire cutting machine add-on type etc. again.First two mode can all cause big waste for formed product from the aspect of material, produce
The product period is longer, and processing efficiency is low, increased costs；Secondly either machine add-on type or wire cutting machine add-on type again, be all
The direct machine-shaping for continuing raw material considers that the grain size of the microscopic structure of material is not fine and close enough from the attribute of material, reduces
The index of product properties, to reduce the service life of product；Furthermore medical titanium alloy femoral joint forging technology
Complexity, enable such product curing process, form batch production.

And in the femoral joint connection-peg (4) of thin taper below the shaft of femur (3), it is characterised in that: the collodiaphyseal angle section (2)
There are rotor (5) on the outside of upper end, the centre of the rotor (5) and the femoral head end (1) has a fossa trochanterica (6), described
Fossa trochanterica (6) is the low progressive recesses structure in intermediate high two sides.
Further, as an improvement project of the invention, it is characterised in that: extend from the fossa trochanterica (6) lower end
Vertical masonry joint channel-shaped thick line (7) out, thick line (7) lower end are connected with the shaft of femur (3) upper end.
Further, as an improvement project of the invention, it is characterised in that: the femoral head end (1) and the neck
Have neck of femur recessed (8) between dry angle section (2), recessed (8) upper end of neck of femur is recessed with cylindrical cross-section, the neck of femur
Recessed (8) lower end has planar recess, and connects with the collodiaphyseal angle section (2).
Further, as an improvement project of the invention, it is characterised in that: the thick line (7) has three.
Further, as an improvement project of the invention, it is characterised in that: collodiaphyseal angle section (2) surface has
More than one set transverse direction groove.
Further, as an improvement project of the invention, it is characterised in that: the collodiaphyseal angle section (2) has 127 °
To 132 ° of corner.
By above technical scheme, the present invention is by being rationally arranged femoral head end, collodiaphyseal angle section, shaft of femur, femoral joint
Connection-peg, rotor, fossa trochanterica, thick line and the recessed structure of neck of femur shape and position, be bonded human femur under loading practical structures, using
The pain of sufferer is reduced in the process.
By the way that the corner structure of special angle is arranged, the fossa trochanterica of lateral groove and specific shape is disposed, femur is helped to close
Section is preferably combined with human muscle, accelerates rehabilitation speed.
By using the manufacturing process of forging processing, keep the key position size Control of femoral joint more accurate, surface
Smoothness reaches standard, while obtaining preferable Mechanical Property of Metal, and by manufacture precision die, it can be achieved that accurate is large quantities of
Amount production, further reduces the cost.
