Description

DESCRIPTION Hip Used in Femral Head and Acetabulum Bone Deformations Prosthetic Systems Technical Area The invention occurs in the femoral and acetabulum bones in the hip joints. With hip prosthesis systems used to treat the resulting deformation Prior Art It is used in cases where the hip joint cannot function and the hip The name of the platinum hip prosthesis made of metal compatible with the body that replaces the joint are given. Hip replacements are used in hip fractures and in conditions such as cancer. It is used in cases where the joint needs to be removed.

Hip prostheses in the current technique are used in different amounts. It cannot be applied to deformations. Solution for different deformation amounts Since it is not possible, it prolongs the operation times considerably.

Hand tools used in hip prosthesis in the current technique designs are inadequate. The inadequacy of the designs also shortens the operation times. it is quite lengthy.

In the European patent document with the code EP2512379 in the current technique Partial hip replacement is mentioned. contained in the aforementioned patent document. prosthesis, surface treatment of the prosthetic component and optimized geometry of articulation By combining it, it reduces friction and wear in partial hip prosthesis.

The acetabulum is carved into the bone. Either the carved acetabulum or the femoral bass one of the articulated surfaces, that of the prosthesis, is spherical so that it is filled with fluid. a gap is created in the important load transfer area. with Akiskan The filled void is a circular shape in which the concave and concave components are compatible. It is made leakproof with the contact area. Preferred surface treatment to bone which causes very low coefficient of friction and high wear resistance, through the diamond-like coating. Prosthetic bass, a perforated shell A femoral neck screwed onto the femur with a conventional root or It is fixed to the femur with a prosthesis, so that it is partially occupied by the bone. it is covered and towards the center where it rests on the hollowed out cortex of the calcar region. partially exposed in the downward direction. contained in the said patent document. The prosthesis cannot be applied in different amounts of deformations. Moreover Due to the design of the prosthesis, the hand tools used during assembly are quite high.

The large number of hand tools used prolongs the operation time.

The subject of the invention is the hip replacement system; bipolar cup (1), wear plate (2), segment (3), head (4), proximal femoral shaft (5), tissue holes (6), Bolts (7), hip prosthesis cap (8), hip prosthesis connector area (9)I support nail (stem) (10), screws (ll), acetabulum (12), total system wear plate (13), and angle adjustment includes the notch (14).

Ti6AI4V ELI as hip replacement proximal femur body (5) material (Grade 23) was used. Used in hip prostheses in the current technique Yield and % elongation values are 1.5 times higher than Ti 4 material. Flowing When the value and % elongation value are taken into account, it is more difficult to use with small diameter implants. greater strength is provided.

Hip replacement systems up to 250 mm deformations applicable. Hip replacement proximal femoral body (5) and support nail (10) are connected to each other with spacer part (connection module). In this case the hip As the deformation increases in the region where the prosthesis will be placed, the spacer pieces end to end. They are attached to each other like a puzzle piece and can extend the length of the prosthesis.

Spacer parts offer solutions up to 250 mm.

Ti6Al4V on hip prosthesis body surfaces for bone-implant attachment A special chemical etching process is applied to the E LI (Grade 23) material.

After the chemical roughening process, the surfaces are sandblasted and the prosthesis its adhesion to the area driven into the bone is increased.

The surface of the hip prosthesis body surfaces on the electrodes in an electrolytic environment. As a result of the reactions occurring, the anodic oxidation process is carried out. biocompatibility is increased.

The hip prosthesis valve in the hip prosthesis systems that are the subject of the invention (8) and due to the uniform convector in the proximal femoral body (5), different diameters and lengths of support nails (10) can be connected to the body.

Tissue holes (6) on the hip prosthesis body, which is the subject of the invention are available. The tissue holes (6) are used to attach the tendons.

Since the places where the muscles connect to the bone are cut during the surgery, Since there is no place to attach, it is placed on the prosthesis so that the tendons can be attached. tissue holes (6) are left.

In the surgery, incisions between 45mm and 250mm at 10”mm intervals are given to the physician. opportunity is offered. Between 45 mm and 250 mm given to physicians in surgery incision possibility, hip prosthesis deformations up to 250 mm regarding its implementation. Surgery as much as the size of the deformed area During the incision is made. As spacer parts are a solution up to 250 mm Physician surgical operation on the area between 45 mm and 250 mm can apply.

Thanks to the angle adjustment notch (14] in the hip prosthesis cover (8) The stems (10) placed in the bone are brought to the desired angle.

Hip in the application set to be used in the surgical operation There are special hand tools for the prosthesis. The hip used in the current technique While 158 hand tools are used in the prosthesis, the subject of the invention is in the hip prosthesis system. this piece is 58”. By reducing the mentioned menstruation, the operation times are reduced by 40%. shortened. Deformations of the hip replacement that are too extensive solution, with a single surgical operation and a single set, the prosthesis being the solution it provides. The fact that one set of hand tools is sufficient will reduce the number of hand tools. is reducing.

The subject of the invention is the hip prosthesis, repair of bone tissues in the limbs. Reconstruction of tissue as a result of loss due to various reasons Compatible with Diaphyseal and Arthrodesis Endoprosthesis systems used for is working. Hip prostheses and Diaphyseal and Arthrodesis Endoprosthesis Systems compatible with each other, stems of the same design (10] and connector provides regions (9).
