Abstract
The utility model discloses a medical implantation device. The medical implantation device is composed of a hollow pipe 1, a plugging object 2 and a multi-hole tantalum layer 4. The upper end of the hollow pipe 1 is a spherical surface 5, and a plurality of through holes 5 are formed in the pipe wall of the hollow pipe. The multi-hole tantalum layer 4 covers the inner wall of the hollow pipe. According to the structure, fixing intensity of the medical implantation device is improved after the medical implantation device is implanted, fixing effect and load-bearing functions of the medical implantation device are strengthened, biocompatibility of the medical implantation device is improved, and the medical implantation device facilitates fast post-operation healing and recovery.
Description
Technical field
This utility model relates to a kind of medical embedded device, relates in particular to the medical embedded device that a kind of good fixing effect, heavy burden function are strong, the postoperative healing is fast.
Background technology
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.For than young patient, must the filling support after sequestrum is removed so that the loaded down with trivial details and many complication of body bone lobe and the filling of free bone piece operation are taken from the performance of postoperative heavy burden function.At present, having used a kind of fusion device that is used to support lumbar vertebra clinically, is a cylindrical shape, the equal opening of its upper/lower terminal, for lumbar vertebra interlock mutually, two ends are dentation up and down, have through hole on wall body.After in this implanting device, being packed to osseous tissue implantation lumbar vertebra,, make the osseous tissue of filling and its osseous tissue on every side of implantation back be communicated with healing by the through hole on upper and lower opening and the wall body.
Also be not exclusively used in the filling of femoral head neck region at present both at home and abroad clinically and support the implanting device 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 implanting device of supporting role.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 from the body osseous tissue, as band blood fortune or not with blood fortune from body bone piece, skeletal grain etc., the loaded down with trivial details not easy to operate and many complication of performing the operation.
Therefore, demand developing that a kind of good fixing effect, heavy burden function are strong, biocompatibility outstanding, the medical embedded rapidly device of healing urgently, can retain in the body for a long time and support the downright bad femoral head that subsides.
The utility model content
At the above-mentioned defective that prior art exists, this utility model aims to provide a kind of good fixing effect, the heavy burden function is strong, the postoperative healing is fast medical embedded device.
To achieve these goals, this utility model by the following technical solutions: medical embedded device is made up of hollow pipe, tamper, porous tantalum layer; Described hollow pipe upper end is a spherical, and tube wall has a plurality of through holes; Described porous tantalum layer is covered in described hollow pipe inwall.
As the improvement to the technical program, described porous tantalum layer porosity is between 35% and 60%.
As the improvement to the technical program, described hollow pipe outer surface of tube wall is provided with rough coatings.
Compared with the prior art, this utility model has improved the constant intensity after medical embedded device is implanted owing to adopted technique scheme, consolidated fixed effect, strengthen the heavy burden function, improved the biocompatibility of structure, helped postoperative quickly-healing and recovery.
Description of drawings
Fig. 1 is the structural representation of this utility model embodiment.
Among the figure: 1 hollow pipe, 2 tampers, 3 through holes, 4 porous tantalum layers, 5 sphericals.
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 medical embedded device, as shown in Figure 1, medical embedded device is made up of hollow pipe 1, tamper 2, porous tantalum layer 4; Described hollow pipe 1 upper end is a spherical 5, and tube wall has a plurality of through holes 3; Described porous tantalum layer 4 is covered in described hollow pipe 1 inwall.
In order to realize further optimization, described porous tantalum layer 4 porositys are between 35% and 60%.
In order further to strengthen fixed effect, described hollow pipe 1 outer surface of tube wall sprays roughening and handles, and rough coatings promptly is set.
Hollow pipe adopts the higher metal or alloy of mechanical strength to make usually, as titanium alloy.
In clinical manipulation, at first the femoral head that necrosis is subsided carries out sequestrum removing decompression, recharges an amount of osseous tissue in medical embedded device, and embedding is real then.Drill through with drill bit and to intend behind the interplantation passage it being implanted to the precalculated position.Place opening to realize sealing tamper, prevent that osseous tissue from overflowing.
After medical embedded device was implanted, its inner osseous tissue was in communication with the outside via the through hole on porous tantalum layer and the tube wall.Porous tantalum can play the effect that starts and promote bone tissue growth.After treating that bone tissue growth is finished, the interaction energy of the inside and outside sclerotin of implanting device strengthens the constant intensity of implanting device, strengthens its fixed effect, thereby improves its heavy burden function.Hollow pipe upper end spherical enters the precalculated position when helping to implant fast, is convenient to implant procedure.
Claims (3)
