Embodiment Construction

[0021] See Figure 1. The main body of the intramedullary nail 1 in the present invention can be in a variety of structural forms, such as interlocking intramedullary nails, intramedullary nails with inner cores, etc., no matter what the form, its basic structural shape is a long columnar body, and the tail end has a There are nail tail caps. The uniqueness of the present invention is to make the nail tail cap 2 connect the tail wire 3, and the tail end of the tail wire 3 connects the metal marking body 4 again. Tail wire 3 can adopt medical high-strength flexible ceramic wire or other high-strength wires. The metal marker 4 can be a circle, a polygonal sheet or a ring, and it is a circle in the figure, with a diameter of 3-5 mm and a thickness of 1-2 mm. The metal marking body 4 is medical stainless steel.

[0022] The implantation and removal method steps of this intramedullary nail will be described in detail below in conjunction with FIG. 1 .

Abstract

The present invention relates to a tail filament intramedullary nail and its implantation and taking-out method. Said intramedullary nail is made into the form of column, its tail end is equipped with nail tail cap, and is characterized by that the nail tail cap is connected with tail filament, and the tail end of said tail filament is connected with a metal marked body. The implantation method includes the steps of cutting implantation hole, implanting and fixing intramedullary nail and suturing implantation hole; and the taking-out method includes the steps: cutting taking-out hole, removing fixing nail of intramedullary nail and suturing the taking-out hole.

Description

technical field [0001] The invention relates to a method for implanting and taking out an intramedullary nail for butt joint treatment of long tubular bones, belonging to the technical field of orthopedic medical appliances. Background technique [0002] Intramedullary nails are currently the preferred internal fixation device in the treatment of long tubular bone fractures in the extremities. Through the elastic fixation of the central axis, the broken ends of the fracture can bear axial pressure evenly, improve the ability of anti-bending and anti-rotation, and avoid harmful effects such as shearing and twisting. Stress, to overcome the stress shielding effect caused by eccentric fixation to the greatest extent, when closed reduction or small incision reduction surgery is used for implantation, the exposure time of the incision is short, which is beneficial to reduce iatrogenic pollution, and can obtain a high fracture healing rate , which solves many complex problems of i...
