Abstract
The utility model discloses a latticed metal orthopedic implant. The surface layer of the implant is provided with three-dimensional mesh holes which include a plurality of holes which are inward from the surface of the implant, and transverse hole channels communicated with parts of or all the holes. After the latticed metal orthopedic implant is implanted to the patient suffering bone diseases, bone cells can grow in the holes and the hole channels of the three-dimensional mesh holes in an embedding way and surround and lock, thereby the effect of preventing the implant and bone from separating and loosening is effectively is achieved for a long time.
Description
Technical field
This utility model relates to a kind of latticed metal orthopaedics implant.
Background technology
People's bone often needs to use tabular or column orthopaedics implant merges, fills, connects, supports the osseous lesion defect or alternative when suffering from situation such as tumor, degeneration or wound, congenital malformation.The material that is used for the orthopaedics implant has a lot, for example from body bone, homogeneous allogenic bone, bioceramic, silica gel and metal material or the like, wherein the various orthopaedics implants of being made by metal material use the most extensively, but skeleton can't produce with the interface of metal surface applying and combine biology after all, As time goes on the loosening trend of sclerotin and metal material disengaging can appear gradually, gives the stable hidden danger of bringing of implant.
The utility model content
The purpose of this utility model provides a kind of metal orthopaedics implant that prevents long-term loosening.
For achieving the above object, this utility model is taked following design:
A kind of latticed metal orthopaedics implant is characterized in that this implant top layer has three-dimensional mesh, and described three-dimensional mesh comprises that several are from the implant surfaces hole inwards and the horizontal duct in connected component or whole described holes.
This implant is plate-like or column.
Described three-dimensional mesh is arranged in the entire body structure of described metal orthopaedics implant.
Described three-dimensional mesh is arranged in the partial structurtes of described metal orthopaedics implant, and the remainder structure is the compact metal body.
Described horizontal duct is monolayer duct or multilamellar duct.
It adopts medical metal to make.
The surface of described three-dimensional mesh has hydroxyapatite coating layer.
The utility model has the advantages that:
1, the latticed metal orthopaedics of this utility model implant, this implant top layer has three-dimensional mesh, and three-dimensional mesh comprises that several are from the implant surfaces hole inwards and the horizontal duct in connected component or whole holes.After patient suffers from osteopathia and implants this latticed metal orthopaedics implant, in hole that osteocyte can the chimeric three-dimensional mesh of growing into and the duct and around locking, reach and prevent effectively muchly that implant and sclerotin break away from and become flexible effect.
2, the latticed metal orthopaedics of this utility model implant, three-dimensional mesh is arranged in the partial structurtes of metal orthopaedics implant, and the remainder structure is the compact metal body.The compact metal body be the difference damaged according to patient's sclerotin and biomechanics needs and at the core of suitable position such as implant or seamed edge position or other position to bear big mechanical loading for example tension, resistance to compression, bending resistance, antitorque function.
3, the latticed metal orthopaedics of this utility model implant, wherein laterally the duct is the multilamellar duct, if consider compact metal body volume need be designed in order to bear big mechanical loading size when big, also can adopt monolayer attached to the latticed duct of compact metal surface.
4, the latticed metal orthopaedics of this utility model implant, wherein the surface of three-dimensional mesh has hydroxyapatite coating layer, has the function of inducing osteocyte to grow into.

The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3, the latticed metal orthopaedics of this utility model implant 1 is characterized in that this implant top layer has three-dimensional mesh, and three-dimensional mesh comprises that several are from the implant surfaces hole 2 inwards and the horizontal duct 3 in connected component or whole holes 2.
This implant 1 is plate-like (as shown in Figure 3) or column (as shown in Figure 1 and Figure 2) or other shape.
Three-dimensional mesh is arranged in the entire body structure (as shown in Figure 1) of metal orthopaedics implant 1.
Three-dimensional mesh is arranged in the partial structurtes of metal orthopaedics implant 1, and the remainder structure is compact metal body 4 (as Fig. 2, shown in Figure 3).
Laterally duct 3 is monolayer duct (as shown in Figure 8) or multilamellar duct (as shown in Figure 9).
The surface of three-dimensional mesh has hydroxyapatite coating layer, and this hydroxyapatite coating layer can adopt conventional plasma spraying method or the heavy collection method of electrochemistry to form.
Laterally duct 3 can be to be arranged in parallel or arranged crosswise or reticulate layout.
The processing and fabricating method of the latticed metal orthopaedics of this utility model implant is: size and shape according to the operation needs are set up latticed metal orthopaedics implant physical model in electronic computer, adopt laser or high-power electron beam processing method melt molding then, can also cast or the metal orthopaedics implant blank surface etch of forging molding, erode away needed mesh with methods such as spark machined, chemical attacks, also can obtain required mesh-structured in addition with powder sintering method.The latticed metal orthopaedics of this utility model implant uses the medical metal material manufacturing with good biocompatibility.
Consider the chimeric needs of growing into of osteocyte, the aperture size of three-dimensional mesh is controlled between 0.05～8mm usually.
The purposes of the latticed metal orthopaedics of this utility model implant is given an example: fusion, filling, connection, support or alternative.As shown in Figure 4, latticed 1 one-tenth bulk of metal orthopaedics implant or column are used for the spinal column intervertebral and play a supportive role, along with osseous tissue in the implant 1 grow into and the most at last adjacent vertebral bodies merge.As shown in Figure 5,1 one-tenth of latticed metal orthopaedics implant is plate-like, is used for substituting of mandibular defect position.As shown in Figure 6,1 one-tenth column of latticed metal orthopaedics implant is used for the connection behind the tubular bone fracture.As shown in Figure 7,1 one-tenth of latticed metal orthopaedics implant is block, is used for the filling of bone defect.
