Embodiment 2

[0047] The difference between the steel plate structure (not shown) of the second embodiment and the first embodiment lies in the specific structure of the locking member. In the second embodiment, the pressing block of the first embodiment is cancelled, and only the pressing nail 41 is provided. When it is necessary to lock between the first steel plate 10 and the second steel plate 20, the pressure nail 41 is directly installed in the locking hole 12 by means of screw connection and pressed on the adjusting tooth 22 of the second steel plate 20, and is squeezed to make it A portion of the teeth of the regulating teeth 22 are deformed. When the pressing nail 41 is tightened, the second steel plate 20 cannot move, which can ensure the stability of locking between the first steel plate 10 and the second steel plate 20 . The locking part of the second embodiment has a simple structure and is easy to operate.

Abstract

The invention provides a steel plate structure which comprises a first steel plate, a second steel plate and a locking piece. A first bone nail hole and a locking hole are formed in the first steel plate, the first steel plate and the second steel plate are stacked, a guiding structure is arranged between the first steel plate and the second steel plate so that the second steel plate can move in the length direction, a second bone nail hole and a plurality of adjusting teeth are arranged on the second steel plate, the adjusting teeth are arranged in the length direction of the second steel plate, and the locking piece is connected to the interior of the locking hole and matched with some adjusting teeth so that the relative position between the first steel plate and the second steel plateis locked. According to the technical scheme, the problems that in the prior art, the length of a steel plate cannot be adjusted, and the requirement for surgery cannot be met are effectively solved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a steel plate structure. Background technique [0002] At present, with the development of spinal internal fixation technology, plate screws are used to treat pathological degeneration in the cervical, thoracic and lumbar spine, and spinal trauma has become very common. However, all the steel plates are of fixed length, which requires the manufacturer to provide a large number of steel plates of different lengths to meet the needs of the operation, thus resulting in an increased inventory. At the same time, it is necessary to prepare a sufficient number of steel plates with specified lengths for intraoperative selection. Thereby cause inconvenience for doctor's operation implementation. Contents of the invention [0003] The present invention aims to provide a steel plate structure to solve the problem in the prior art that the length of the steel plate cannot be adjus...
