Novel thighbone interlocking intramedullary nail

Abstract

The invention discloses a novel thighbone interlocking intramedullary nail which comprises an intramedullary nail body. The intramedullary nail body comprises an intramedullary nail near end and an intramedullary nail far end. The intramedullary nail far end is arranged at the lower end of the intramedullary nail near end. A screw fixing hole is formed in the upper end of an inner cavity of the intramedullary nail near end. A through hole is formed between the cavity and the outside wall of the intramedullary nail near end. A spring is arranged in an inner cavity of a fixing cylinder. A buckleis matched with the through hole. A fixing ring is arranged at the joint of the buckle and the through hole. A right-opposite platform is arranged on the side wall of one side of the intramedullary nail far end. A conical head portion is arranged at the top end of the intramedullary nail far end. According to the novel thighbone interlocking intramedullary nail, by designing the outside wall of the intramedullary nail body into the bent side wall, the intramedullary nail can better fit the physiological curvature of Asian, the plasticizing amount is reduced, the intramedullary nail can be conveniently inserted in a marrow cavity under the effect of the conical head portion, the length of the intramedullary nail body can be adjusted through the buckle and the through hole, and the intramedullary nail can be suitable for different people.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a novel femoral interlocking intramedullary nail. Background technique [0002] The intramedullary nail is an internal fixation device in the bone marrow cavity of the human body. It is a common medical device for treating fractures. Fracture fragments are aligned, fixed, and support a certain gravity, so as to facilitate bone callus growth and fracture healing. There are deficiencies in the existing technology. The problem is that there are certain differences in the matching degree of physiological curvature and different patients. The most important thing is the fixed position of the intramedullary nail in the medullary cavity. If there is a large difference, the healing of the fracture will be displaced, which will have a great impact on the normal life of the patient in the future. Contents of the invention [0003] The purpose of the present invention is to provi...
