The invention provides a device for removing a broken main nail of an intramedullary nail, which belongs to the technical field of medical devices and comprises a handle, a handle ejector, a handle pull sleeve, a connecting nut, a spring, an expansion pull rod, a thrust tube and an expansion tube, and a handle ejector. The left end of the handle is connected with the handle, the right end of the handle push rod extends into the inside of the handle pull sleeve, and the rightmost ends of the two are aligned at the same time, the connecting nut is sleeved on the handle push rod, and then connected with the left end of the handle pull sleeve, the spring is sleeved on the top of the handle On the rod, and set in the space enclosed by the handle top rod and the handle pull sleeve, one end of the expansion rod is set inside the handle top rod, the other end is set outside the handle top rod, and the thrust tube is sleeved on the expansion rod. At the outer end of the ejector rod, the expansion pipe is sleeved on the right end of the expansion rod, and the left end of the expansion pipe is in contact with the right end of the thrust pipe. The invention can simply and safely take out the broken nail at the distal end of the intramedullary nail without increasing the surgical trauma of the patient.
Description
technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a device for taking out a broken main nail of an intramedullary nail. Background technique [0002] At this stage, femoral-tibial intramedullary nailing has become the gold standard for the treatment of lower extremity long shaft fractures. It will be very difficult to remove the distal end of the broken nail, and the removal of the broken nail often causes great damage to the patient, and will increase the surgical trauma to the patient. SUMMARY OF THE INVENTION [0003] In view of this, the present invention aims to provide a simple and practical device for removing the broken main nail of the intramedullary nail without adding additional trauma to the patient. [0004] In order to achieve the above purpose, the technical solution of the present invention is achieved as follows: a device for removing a broken main nail of an intramedullary nail, comprisin...
