Abstract

The utility model discloses an implant. The implant is composed of a hollow duct (1) and porous tantalum filler (2), wherein the hollow duct (1) is filled with the porous tantalum filler (2), and a plurality of round through holes (3) are formed in the duct wall of the hollow duct (1). According to the structure of the implant, the implant is applicable to body parts, such as thigh bones, wherein the body parts need high loading capacity, improves biocompatibility of the structure, reduces rejection reactions of a human body, and reduces occurrence of complications.

Description

A kind of implantation body

Technical field

This utility model relates to a kind of implantation body, relates in particular to a kind of implantation body that is applicable to that femur plantation, heavy burden ability are given prominence to, the human body rejection is few, be difficult for leading to complications.

Background technology

At present, medical implant operation is very general in clinical treatment, and implantation body can be used for the corrupted treatment at each position of health.Avascular Necrosis Of Femur Head is a kind of common clinical disease, and current main therapeutic modality comprises boring decompression, the bone lobe transplanting of band blood fortune and artificial joint replacement etc.In the operation of clinical treatment Avascular Necrosis Of Femur Head, the removing of sequestrum and to refill be committed step greatly affects therapeutic effect and prognosis.Be used for mostly being of filling at present, the loaded down with trivial details not easy to operate and many complication of performing the operation from the body osseous tissue.

Also be not exclusively used in the filling of femoral head neck region at present both at home and abroad clinically and support the planting unit appearance.The patient who is not suitable for using artificial joint replacement treatment for youth be badly in need of a kind of can with from the body synosteosis and bring into play the planting unit of supporting role.Therefore, be badly in need of the implantation body that a kind of ability of heavy burden of research and development is strong, the postoperative rejection is little, result of use is good, thereby solve the problem of many complication at all.

The utility model content

At the above-mentioned defective that prior art exists, this utility model aims to provide a kind of implantation body that is applicable to that femur plantation, heavy burden ability are given prominence to, the human body rejection is few, be difficult for leading to complications.

To achieve these goals, this utility model by the following technical solutions: implantation body is made up of hollow pipe and porous tantalum implant; Described porous tantalum implant is filled in the described hollow pipe; Described hollow pipe tube wall has a plurality of manholes.

As the improvement to the technical program, described porous tantalum implant porosity is between 30% and 65%.

Compared with the prior art, this utility model has been owing to adopted technique scheme, makes the plantation physical ability be applicable to bear a heavy burden the more by force human body of ability of needs such as femur, improved the biocompatibility of structure, reduce the rejection of human body, reduced the generation of complication.

Description of drawings

Fig. 1 is the structural representation of this utility model embodiment.

Among the figure: 1 hollow pipe, 2 porous tantalum implants, 3 manholes.

The specific embodiment

Below by embodiment this utility model is carried out concrete description; be necessary to be pointed out that at this following examples only are used for this utility model is further detailed; can not be interpreted as the restriction to this utility model protection domain, those skilled in the art can make some nonessential improvement and adjustment to this utility model according to foregoing.

Embodiment: a kind of implantation body, as shown in Figure 1, implantation body is made up of hollow pipe 1 and porous tantalum implant 2; Described porous tantalum implant 2 is filled in the described hollow pipe 1; Described hollow pipe 1 tube wall has a plurality of manholes 3.

In order to optimize healing effect, described porous tantalum implant 2 porositys are between 30% and 65%.

In practical operation, at first the femoral head that necrosis is subsided carries out the sequestrum removing, drills through with drill bit then and intends the interplantation passage, implantation body is planted to the precalculated position again.After implantation body's plantation was finished, the through hole on the hollow pipe tube wall played the inside and outside effect that is communicated with.The porous tantalum material can improve the biocompatibility of structure, starts bone tissue growth rapidly and guides sclerotin to be shaped, and reduces the rejection of human body to a great extent.Hollow pipe is made by the metal or alloy with strong mechanical strength, has outstanding heavy burden ability, can realize comparatively ideal result of use.The plantation physical ability of metal or alloy material is greatly avoided the generation of complication.

Claims (2)

1. implantation body, it is characterized in that: described implantation body is made up of hollow pipe (1) and porous tantalum implant (2); Described porous tantalum implant (2) is filled in the described hollow pipe (1); Described hollow pipe (1) tube wall has a plurality of manholes (3).

2. implantation body as claimed in claim 1 is characterized in that: described porous tantalum implant (2) porosity is between 30% and 65%.
