Abstract

The invention provides a device for taking out broken main intramedullary nails and belongs to the technical field of medical instruments. The device comprises a handle, a handle ejector rod, a handlepull sleeve, a connecting nut, a spring, an expansion pull rod, a thrust tube and an expansion tube, the left end of the handle ejector rod is connected with the handle, the right end of the handle ejector rod extends into the handle pull sleeve, meanwhile, the rightmost ends of the handle ejector rod and the handle pull sleeve are aligned to each other, the handle ejector rod is sleeved with theconnecting nut, the connecting nut is then connected with the left end of the handle pull sleeve, the handle ejector rod is sleeved with the spring, in a space defined by the handle ejector rod and the handle pull sleeve, one end of the expansion pull rod is arranged in the handle ejector rod, the other end of the expansion pull rod is arranged outside the handle ejector rod, one end, arranged outside the ejector rod, of the expansion pull rod is sleeved with the thrust tube, the right end of the expansion pull rod is sleeved with the expansion tube, and the left end of the expansion tube makes contact with the right end of the thrust tube. The device can simply and safely take out far-end broken intramedullary nails on the basis that operation trauma of patients is not increased.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a device for taking out broken main nails of intramedullary nails. Background technique [0002] At present, femoral tibial intramedullary nailing is the gold standard for the treatment of long bone fractures of the lower extremities. Taking out the distal end of the broken nail will become very difficult, and taking out the broken nail often causes very large damage to the patient, and increases the surgical trauma to the patient. Contents of the invention [0003] In view of this, the present invention aims to propose a device for taking out a broken main nail of an intramedullary nail that is simple and practical and does not increase additional trauma to the patient. [0004] In order to achieve the above-mentioned purpose, the technical solution of the present invention is achieved in the following way: a device for taking out a broken main nail of an ...
