Through the splendid biocompatibility that utilizes the titanium material to have, it is internal to make annular titanium hoop board 1 can direct implantation, need not carry out the secondary operation and take out, the risk that the secondary operation brought has been reduced, and its good plasticity makes it to carry out the size regulation of annular diameter through opening 11, with the bone size of adaptation different patients, and adopt cable 2 to bind the locking fixed to the diameter of annular titanium hoop board 1, adopt bone nail 3 to fix annular hoop board on patient's diaphysis again, and the mesh 14 of seting up on the annular titanium hoop board 1 plate body can make things convenient for the bone length to go into, improve the healing rate of patient's broken bone.
Example 1
The embodiment 1 of the utility model provides a novel fracture fixation prosthesis, it includes: annular titanium hoop plate 1, cable 2 and bone nail 3.
The annular titanium hoop plate 1 has excellent biocompatibility, uniform surface and good fatigue resistance, and is beneficial to combination with bones, so that the annular titanium hoop plate 1 is implanted without taking out the annular titanium hoop plate after a secondary operation, and the risk caused by the secondary operation is reduced. As shown in fig. 2, the annular titanium hoop plate 1 is provided with an opening 11 along the length direction of the body, and the annular titanium hoop plate of suzuohu is sleeved on the fractured bone of the patient through the opening 11 to butt and fix the upper and lower fractured bones, as shown in fig. 1. Meanwhile, because the annular titanium hoop plate 1 has good plasticity, the annular titanium hoop plate 1 can adjust the size of the annular diameter through the opening part 11 to adapt to the bone size of different patients, and completely meets the requirements of different people on the titanium plate fixator due to different bone diameters, and is not limited to the fracture of a bone part, such as: fractures of humerus, femur and the like can be fixed by implanting the prosthesis.
In order to ensure the relative fixation between the annular hoop plate and the bone of the patient, a plurality of positioning nails 12 which are arranged in a protruding manner in the radial direction are distributed on the inner side of the plate body of the annular titanium hoop plate 1, when the annular titanium hoop plate 1 is sleeved on the bone of the patient, the positioning nails 12 are nailed into the bone of the patient, so that the relative movement between the annular hoop plate and the bone is avoided, and the stability of the implantation of the prosthesis is ensured.
After annular titanium hoop board 1 suit is on patient's broken bone department, adopt cable 2 to bind locking fixed annular titanium hoop board 1, for avoiding cable 2 to take place the displacement on annular titanium hoop board 1, as shown in figure 2, evenly distributed is equipped with a plurality of annular cable recess 13 that set up around its plate body direction of encircleing from top to bottom on the plate body outer wall of annular titanium hoop board 1 for carry on spacingly to cable 2, cable 2 inlays to be established in the cable recess 13 to bind locking fixed annular titanium hoop board 1.
On the annular titanium hoop plate 1, a plurality of meshes 14 are arranged on the plate body between the adjacent annular cable grooves 13, so that the bone can grow conveniently, and the healing rate of the broken bone of a patient is improved. Specifically, as shown in the figure, a plurality of rows of meshes 14 are uniformly distributed on the upper and lower sides of the plate body of the annular titanium hoop plate 1, the hole pitch between the single row of meshes 14 is 7.5mm, and the diameter of each mesh 14 is 6 mm. Meanwhile, the cable 2 can also be crossed and wound in the meshes 14 between the adjacent rows to realize the binding and locking of the annular titanium hoop plate 1, so that the force transmission is facilitated, and the stress concentration phenomenon is avoided, the meshes 14 between the adjacent rows are distributed in a regular triangle, and specifically, the adjacent meshes 14 on the upper side and the lower side of the annular cable groove 13 are distributed in a regular triangle.
As shown in fig. 3, after the cable 2 binds and locks the annular titanium hoop plate 1, the annular titanium hoop plate 1 is fixed on the bone of the patient by using the bone nail 3, the bone nail 3 is nailed into the bone of the patient through the mesh holes 14 on the annular titanium hoop plate 1, and the diameter of the mesh holes 14 is matched with the diameter of the nail body of the bone nail 3. In addition, the spongy bone particles are filled in the meshes 14 of the annular titanium hoop plate 1, have good bioactivity compatibility and biological bone conductivity, can repair the defect with a small bone defect range, and can further accelerate the healing speed of the broken bone of the patient by filling the spongy bone particles.
It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention, including other drive and transmission means, such as pneumatics, chains, etc. Thus, if such modifications and variations of the present invention fall within the scope of the claims and their equivalents, the present invention is also intended to include such modifications and variations.
