Problems solved by technology

In order to make the locking screw of the implant have the best fixation effect, it is required that the locking screw must be implanted in the bone in a specific direction; due to the difference in the fracture and broken parts, as well as the differences in the bone shape between different individuals, the In clinical application, this locking plate screw system often has a contradiction between the set implantation direction and the optimal implantation direction between the locking screw and the plate, which affects the surgical effect

Embodiment Construction

[0018] Reference attached figure 1 , 2 , A steel plate screw system with universal locking function includes a steel plate 4 and a locking screw. The steel plate 4 is provided with a threaded hole 5; the threaded hole 5 provided on the steel plate 4 is a tapered threaded hole.

[0019] The locking screw includes a threaded rod 1 and a head 2 of the locking screw. The screw head 2 is provided with a universal groove 3. The said universal groove 3 is provided with several longitudinal grooves on the head of the screw. An external thread 8 is provided on the outer circumference of the screw head 2 to match the threaded hole provided on the steel plate 4.

[0020] The external thread provided on the outer circumference of the screw head 2 is a tapered thread.

[0021] A steel plate screw system with universal locking function is used for surgery, choose the best implant direction, install a steel plate 4 with a steel plate threaded hole 5 on the fracture, and use a drill in the best i...

Abstract

The invention relates to a steel plate screw system with a universal locking function. The steel plate screw system with the universal locking function is a surgical operation implantation material system used for fixing and restoration after limb fracture of a human body. The steel plate screw system with the universal locking function is characterized in that the steel plate screw system comprises a steel plate and a locking screw, a screw hole is formed in the steel plate, the locking screw comprises a locking screw threaded rod portion and a screw head, a universal groove is formed in the screw head, and an outer thread is designed on the periphery of the screw head and matched with the screw hole in the steel plate. The screw hole in the steel plate is tapered. The universal groove includes a plurality of longitudinal grooves which are formed in the screw head. The outer thread designed on the periphery of the screw head is a tapered thread.

Description

Technical field [0001] The invention relates to a steel plate screw system with universal locking function, which is a surgical implant system used for fixed reduction of human limbs fractures. Background technique [0002] Human bones are originally soft, elastic and plastic when they are just formed. As the age grows, the composition of cartilage decreases and the composition of hard bones gradually increases, and fractures begin to occur easily. [0003] Clinically, the locking plate screw system used for orthopedic internal fixation is mainly composed of a locking screw and a plate. In the locking plate screw system, the angle between the locking screw and the plate is preset. In order to make the locking screw of the implant have the best fixation effect, it is required that the locking screw must be implanted in the bone in a specific direction; due to the different fractured parts and the difference in bone shape between different individuals, In clinical applications, this...
