Intramedullary nail accurate positioning mounting frame

Abstract

The invention discloses an intramedullary nail accurate positioning mounting frame. The mounting frame comprises a cross rod; a disc is fixedly connected to the left end of the cross rod; a circular ring is in clearance fit with the outer wall of the disc through a circular groove; and a clamping assembly is arranged inside the circular ring. According to the intramedullary nail accurate positioning mounting frame, through cooperation of the circular ring, the disc, the cross rod and the clamping assembly, the circular ring can be driven to rotate by pulling a pull rod when the mounting frameis in use, so that three clamping rods are driven to rotate at the same time to clamp and fix intramedullary nails with different sizes. Therefore, the application range is expanded, nailing accuracyis improved at the same time, nailing positions of the intramedullary nails are more accurate, and the success rate of an operation is improved. Through cooperation of the cross rod, the circular ring, the disc and an adjusting assembly, the device can be adjusted and fixed by contrasting the cylinder and scales on the outer wall of an upright rod, so that nailing depths of the intramedullary nails after fixing are observed and controlled, and a patient is prevented from being damaged for the second time due to inconsistent nailing depths of the intramedullary nails caused by incorrect operation of an opearator.

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
