Embodiment 1

[0019] like figure 1 and Figure 4 The patella locking plate shown includes a bone plate main body 1 and a shaper 2, the front of the bone plate main body 1 is in the shape of a ring, the side of the bone plate main body 1 is arc-shaped, and the bone plate The main body 1 is connected with two intersecting fixing strips 3, and the annular surface of the bone plate main body 1 is provided with 8 or more threaded holes 4, and the two ends of the fixing strips 3 are respectively connected Inside a threaded hole 4 , the shaper 2 is connected in the threaded hole 4 , and a pressure hole 5 is opened at the intersection of the two fixing bars 3 . The bone plate main body 1 is made of pure titanium or stainless steel. The bone plate main body 1 is made of pure titanium or stainless steel; the side curvature of the bone bone plate main body 1 matches the outer surface curvature of the human patella; the shaper 2 is composed of an outer hexagon and a circumscribed The threaded end is...

Embodiment 2

[0022] The structure of the second embodiment is roughly the same as that of the first embodiment, and the difference lies in the number of threaded holes 4 provided on the annular surface of the bone plate main body 1. The structure of the bone plate main body 1 in the second embodiment is as follows: figure 2 As shown, the annular surface of the bone plate main body 1 is provided with 10 threaded holes 4, the angle between the two adjacent threaded holes 4 is 36°, and the two The fixing strip 3 is connected in the bone plate main body 1 at an included angle of 72°. The number of locking screws that need to be connected will be different according to the actual situation. In the second embodiment, there are 10 threaded holes 4 on the main body 1 of the bone plate. At this time, people can connect 10 locking screws, which has the advantages of simple structure and high safety. Suitable for clinical needs, the bone plate has the advantages of high bending strength.

Embodiment 3

[0024] The structure of the third embodiment is roughly the same as that of the first embodiment, the difference lies in the difference in the number of threaded holes 4 provided on the annular surface of the bone plate main body 1, the structure of the bone plate main body 1 in the third embodiment is as follows image 3 As shown, the annular surface of the bone plate main body 1 is provided with 12 threaded holes 4, the angle between the two adjacent threaded holes 4 is 30°, and the two The fixing strips 3 are connected in the main body 1 of the bone plate in the shape of a right cross. The number of locking screws that need to be connected will be different according to the actual situation. In the third embodiment, there are 12 threaded holes 4 on the main body 1 of the bone plate. At this time, people can connect 12 locking screws, which has the advantages of simple structure and high safety. Suitable for clinical needs, the bone plate has the advantages of high bending s...

Abstract

The invention relates to a patella locking plate which comprises a bone plate set main body and shaping devices. The front side of the bone plate set main body is of a circular ring shape; the lateral surface of the bone plate set main body is of an arc shape; two mutually crossed fixed strips are connected to the inside of the bone plate set main body; 8 or more threaded holes are formed on the circular ring-shaped face of the bone plate set main body; both ends of each fixed strip are respectively connected to the inside of one threaded hole; the shaping devices 2 are connected to the insides of the threaded holes; a pressurizing hole is formed at the crossed position of the two fixed strips. According to the invention, by design of the shaping devices, people can more rapidly and accurately screw in locking screws so as to fulfill the aim of more firmly connecting the bone.

Description

technical field [0001] The invention relates to a medical orthopedic tool, in particular to a patella locking plate. Background technique [0002] The existing medical plate for the patella is mainly composed of two arc-shaped plates and an intermediate connecting screw. Such a medical plate for the patella is in the shape of a claw. When in use, the claws of the plate are easily stuck on the articular surface, which brings great inconvenience to the user. It was a lot of pain, and the two steel plates were fixed with screws, which was unstable and could not provide a good fixation effect, and the treatment effect was poor. Contents of the invention [0003] The technical problem to be solved in the present invention is to enable people to screw in locking screws more quickly and accurately through the design of the shaper, so as to achieve the purpose of connecting bones more firmly; and to provide a patella locking plate. [0004] In order to solve the above-mentioned t...
