Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to an adjustable orthopedic nail locking device. Background Art

[0002] The nail locker plays a vital role in orthopedic reduction. It is mainly used for the fixation and reduction of fractures to help patients recover bone health faster. As an advanced orthopedic device, the nail locker often needs to be customized or the fracture plate needs to be bent and adjusted by tools according to the different fracture locations of the patients, which takes a lot of time and leads to low work efficiency.

[0003] The patent document with the announcement number CN212521970U discloses an orthopedic reduction nail locking device, which relates to the field of medical device technology and solves the problem that although there are many types of existing fracture plates, the fracture plate structure required to match them is not compatible with the existing multiple types of fracture plates due to the different fracture sites. The orthopedic reduction nail locking device includes a nail locking device body and a connecting disc. The nail locking device body is composed of a disc, a frustum-shaped mounting hole, an annular T-shaped slide groove, and an annular L-shaped slide groove. A frustum-shaped mounting hole is opened at the axial part of the top surface of the disc. The traditional fracture plate nail locking device has an integrated structure and adopts a small-volume nail locking device body. The corresponding number of nail locking device bodies can be freely selected according to the required nail insertion site of the bone screw. There is no need to customize the corresponding fracture plate or adjust the fracture plate structure by bending the tool. It is more convenient to use, and because of its small size, it will not cause inconvenience to the subsequent patients when wearing clothes. However, the patent still has the following problems in actual use: The nail locker adjusts the distance between the main bodies of the nail locker by setting a medical steel wire rope. However, since the length of the steel wire rope is difficult to adjust again, the accuracy of the distance between the main bodies of the nail locker is low when the nail locker is used, which affects the applicability of the nail locker when used. In addition, the steel wire rope in the nail locker has poor support and is prone to bending during use, causing the main bodies of the nail locker at both ends to shrink and deform, thereby causing displacement of the bone screws and causing secondary injuries to the patient, thereby affecting the patient's recovery.

[0004] Therefore we have proposed a kind of adjustable orthopedic nail locking device, so as to solve the above-mentioned problem. Summary of the invention

[0005] The purpose of the present invention is to provide an adjustable orthopedic nail locker to solve the problem that the nail locker adjusts the distance between the nail locker bodies by setting a medical steel wire rope, but since the length of the steel wire rope is difficult to adjust again, the accuracy of the distance between the nail locker bodies when the nail locker is used is low, thereby affecting the applicability of the nail locker when used, and the steel wire rope in the nail locker has poor support and is prone to bending during use, resulting in the contraction and deformation of the nail locker bodies at both ends, thereby causing the displacement of the bone screws and causing secondary injuries to the patient, thereby affecting the patient's recovery.
