An intramedullary nail precise positioning installation frame

Abstract

The invention discloses a precise positioning installation frame for intramedullary nails, which comprises a cross bar, the left end of the cross bar is fixedly connected with a disk, the outer wall of the disk is fitted with a circular ring through the gap of the circular groove, and the inner side of the circular ring With clamping components. The intramedullary nail is precisely positioned on the installation frame. Through the cooperation of the ring, the disc, the cross bar and the clamping component, the device can drive the ring to rotate by pulling the pull rod when the device is in use, and then drive the three clamping rods to rotate at the same time. The size of the intramedullary nail is clamped and fixed, thereby expanding the scope of application, and at the same time improving the accuracy of the nail, making the nailing position of the intramedullary nail more accurate and improving the success rate of the operation. The cooperation of the device allows the device to be adjusted and fixed by the cylinder against the scale on the outer wall of the vertical rod, and then the depth of the intramedullary nail after fixation can be observed and controlled, so as to avoid improper operation of the user and cause the depth of the nail to be inserted incorrectly. First, to avoid secondary harm to patients.

Description

technical field [0001] The invention relates to the technical field of an intramedullary nail precise positioning mounting frame, in particular to a precise positioning mounting frame for an intramedullary nail. Background technique [0002] The intramedullary nail is an orthopedic internal fixation device in the medical equipment. There is more than one strip-shaped decompression plane on the surface of the nail rod. The decompression plane can be from the proximal end of the intramedullary nail rod to the distal end of the intramedullary nail rod. A locking screw positioning screw hole is set at the proximal end of the intramedullary nail rod. , Connecting sets of positioning slots. [0003] The precise positioning mounting frame for intramedullary nails in the prior art cannot clamp and fix intramedullary nails of different sizes, and the fixing positions are different, which makes the scope of application narrow, and the practicability and flexibility of use are poor. ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a precise positioning mounting frame for intramedullary nails to solve the problem that the precise positioning mounting frame for intramedullary nails in the prior art proposed in the above background technology cannot clamp and fix intramedullary nails of different sizes, and The fixed positions are different, which narrows the scope of application, poor practicability and flexibility, and at the same time makes the nailing position of the intramedullary nail inaccurate, reducing the success rate of surgery
