CN2305966Y - Artificial body for generating bone and joint - Google Patents

Abstract

The utility model provides an artificial body for generating a bone and a joint, which relates to a medical utensil for an orthopaedic operation. The utility model is characterized in that bone or cartilage generation promoting factors and a compound carrier 3 with bioactivity are arranged in a titanium net frame 1 in the shape of a bone and a joint. The utility model is implanted on the bone and the joint of a disease or damaged position through a surgical operation, and can newly generate new bone and joint with the shape similar to that of the bone and the joint of the disease or damaged position in the titanium wire frame 1 through the functions of life-time reconstruction and regeneration of the bone tissue of a human body.

Description

Body takes place in bone, joint

This utility model belongs to the orthopedic medical apparatus and instruments of using, and body takes place for specifically a kind of bone, joint.

As everyone knows, plant and change for the orthopedic general employing prosthese in bone, joint (artificial bone, joint) sick, that decrease at present, these artificial prosthesis adopt metal or polymer substance production, service life is short, complication is many, and along with the increase of population ages, inadaptability is more outstanding.

This utility model purpose is, provides a kind of bone, joint that body takes place, and arrives bone, arthrosis, damage position by surgical replacement, thereby grows self bone, joint.

For achieving the above object, this utility model can be realized by following measure, is provided with the carrier of short bone or the cartilage generation factor and biologically active in the titanium rack of bone, joint shape.

Body takes place for this utility model bone, joint can produce function by the regeneration of body bone tissue by surgical replacement to human body bone, arthrosis, damage position, thus self bone that hair growth promoting makes new advances, joint.

This utility model is described in detail by embodiment below in conjunction with accompanying drawing, wherein

The body sketch map takes place in Fig. 1 for this utility model is key, also be the sketch map of a kind of embodiment.

Fig. 2 for the body sketch map takes place in this utility model joint, also is a kind of embodiment sketch map.

Fig. 3 for this utility model bone and joint generation body sketch map, also is a kind of embodiment sketch map.

Shown in Figure 1, when key sick, when the damage position need rebuild, at first titanium net 1 is processed into disease, decrease position backbone's shape, in the inner chamber of titanium net 1, fill then and (for example: decalcified bone matrix have bioactive complex carrier, the decalcification bone, hydroxyapatite, the spongy bone granule, from the body bone, allograph bone etc.) and short bone or the cartilage generation factor (BMP, bFGF, POGF etc.) 3, be fixed with wing plate 2 at titanium net 1 two ends, wing plate 2 is fixed on during use does not have disease, on the backbone (or joint) who decreases, by surgical operation this utility model is planted disease, the key position of decreasing, because the lifelong reconstruction of body bone tissue, the regeneration characteristics, can participate in the metabolic backbone of human body thereby in titanium net 1, regrow out one, backbone that this is new and former disease, the key shape of decreasing is similar or identical, and titanium net 1 is stayed a key interior part as area of new bone.

When this utility model uses, blood vessel, nerve can take place to reconstruct and metabolism in the body by grow into bone, joint of the mesh on the titanium rack 1, and at joint part, soft of joint can grow from mesh, and being distributed to equably outside the titanium rack 1, serves as to rely on to form articular surface with titanium rack 1.

Shown in Figure 2, be used to plant the embodiment that changes disease, decreases the joint as one, when the joint take place sick, decrease and when needing to rebuild, at first according to sick, as to decrease joint shape processing titanium rack 1, be fixed with the wing 2 on the titanium rack 1, be filled with the complex carrier 3 of aforesaid short bone or the cartilage generation factor and biologically active thereof in the titanium rack 1, the wing 2 is used for fixing on key (or joint).

Shown in Figure 3, be used to plant the embodiment that changes disease, decreases bone and joint as one, when disease, the reconstruction of damage needs take place in the joint of backbone and end thereof simultaneously, at first titanium net 1 is processed into the bone and the joint shape thereof of disease, damage, titanium net 1 one ends are fixed with the wing 2, be filled with the complex carrier 3 of short bone or the cartilage generation factor and biologically active thereof in titanium net 1 inner chamber, the wing 2 is used for fixing on key (or joint).

This utility model also can be used for diseases such as semiarthrosis, privileged sites bone (for example skull), special bone (for example carpal bone), decreases the reconstruction at position.

Claims (1)

1, body takes place in a kind of bone, joint, it is characterized in that being provided with in the titanium rack 1 of bone, joint shape the complex carrier 3 of short bone or the cartilage generation factor and biologically active.
