Embodiment Construction

[0040] In order to achieve the purpose of the present invention, the present invention will be further described below in conjunction with Example 1.

[0041] Such as figure 1 As shown, in this embodiment, a non-metallic implant screw locking structure is proposed, including a non-metallic implant 1 and a metal screw 2; wherein, the non-metallic implant 1 is provided with a plurality of fixing Holes 11; the front part of the metal screw 2 is a bone thread, and the tail is provided with pointed threads or spikes.

[0042] Such as Figure 2a to Figure 2f As shown, the hole type of the fixing hole 11 on the non-metallic implant 1 is a straight hole or a taper hole or a shallow threaded hole.

[0043] Such as Figure 3a and Figure 3b As shown, the front part of the metal screw 2 has a bone thread 21, and the tail has a pointed thread 22 or a spike 23. The pitch of the pointed thread 22 should be the same as that of the bone thread 21, and the pointed thread 22 can be multiple...

Abstract

The invention provides a nonmetallic implant screw locking structure which is simple in structure, novel in design, simple to produce and very convenient to clinically operate. The nonmetallic implantscrew locking structure is applicable to traumatic bone plates, spinal fusion cages, spinal fixing plates, cervical posterior single-opening door plates, cervical posterior plates, lumbar anterior plates, lumbosacral plates and other nonmetallic implants, and good economic and social benefits can be created gradually.

Description

technical field [0001] The invention relates to the technical field of orthopedic surgery medical instruments, in particular to a non-metallic implant screw locking structure. Background technique [0002] As we all know, the treatment of various fractures, bone defects or bone tissue degeneration should promote bone growth and fusion, and it is necessary to use orthopedic implants, such as bone plates, connecting rods and screw systems. In the past, many orthopedic implants were made of metal materials. become. These materials have many advantages: they are easy to sterilize, are biocompatible, and provide the necessary fixation strength to support or fix bone tissue. However, metal materials also have shortcomings. Its compression modulus is much higher than that of cortical bone, which produces stress shielding and reduces new bone formation, resulting in osteopenia or osteoporosis, and the possibility of refracture. After bone repair, these implants no longer need to b...
