Abstract
The utility model discloses a latticed implant. The latticed implant comprises metal grids (1) and a porous tantalum infill (2). The metal grids (1) are rectangular grids. The porous tantalum infill (2) fills the gaps among the metal grids (1). The latticed implant can adapt to multiple positions of a human body, be fixed more stably, be compatible with good mechanical property and outstanding biological compatibility, and greatly shorten a postoperative rehabilitation process.
Description
Technical field
This utility model relates to a kind of latticed implant, relates in particular to the latticed implant that a kind of strong adaptability, maintenance are stable, quick recovery is given prominence to, is conducive to biocompatibility.
Background technology
Tissue often need substitute, support, fill or merge defected part with implant when wound occurring or damage.The material of implant is mainly autologous tissue, bioceramic, silica gel and metal or alloy material.
In orthopaedics, the most conventional with metal or alloy material.But between common metal or alloy and skeleton, cannot form biological combination, this can cause, and adhesion is not enough, retention effect is poor, the consequences such as inefficacy that easily get loose, and has a strong impact on implantation effect.
Utility model content
In view of the foregoing defects the prior art has, this utility model aims to provide the latticed implant that a kind of strong adaptability, maintenance are stable, quick recovery is given prominence to, is conducive to biocompatibility.
To achieve these goals, this utility model by the following technical solutions: latticed implant is comprised of metal grill and porous tantalum obturator; Described metal grill is rectangular mesh; Described porous tantalum obturator is filled between described metal grill space.
As the improvement to the technical program, described metal grill cross section is square.
As the improvement to the technical program, described metal grill cross section is circular.
Compared with the prior art, this utility model, owing to having adopted technique scheme, makes to implant physical ability and adapts to a plurality of positions of human body, makes implant maintenance more stable, has taken into account good mechanical performance and outstanding biocompatibility, and postoperative rehabilitation process is shortened greatly.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment.
In figure: 1 metal grill, 2 porous tantalum obturators.
The specific embodiment
Below by embodiment, this utility model is specifically described; be necessary to be pointed out that at this following examples are only for being further detailed this utility model; 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 latticed implant, as shown in Figure 1, latticed implant is comprised of metal grill 1 and porous tantalum obturator 2; Described metal grill 1 is rectangular mesh; Described porous tantalum obturator 2 is filled between described metal grill 1 space.
For the ease of processing and manufacturing, described metal grill 1 cross section is square or circular.
Metal grill and porous tantalum obturator are integral sintered forming.
The advantage of metal grill is that flexible structure is changeable, applicable to a plurality of positions such as femur, dentale, joints.The material of metal grill can select to have the metal or alloy of stronger mechanical strength, and size can design according to bearing strength.
Porous tantalum is filled the biocompatibility that physical ability greatly improves structure, starts tissue growth, with tissue, merges well, strengthens adhesion, is conducive to implant maintenance stably for a long time in human body, and postoperative rehabilitation process is shortened dramatically.
