Intramedullary resetting device for thighbone

Abstract

The invention discloses an intramedullary resetting device for thighbone. The intramedullary resetting device comprises an intramedullary resetter and an ultrasonic probe, wherein the intramedullary resetter comprises a distal end and a proximal end, the distal end of the intramedullary resetter goes deep into a medullary cavity of the thighbone, and the ultrasonic probe is arranged at the distalend of the intramedullary resetter and is used for imaging a fracture end of the thighbone. According to the intramedullary resetting device for the thighbone, provided by the embodiments of the invention, real-time monitoring on a thighbone surgery can be achieved through arranging the ultrasonic probe at the distal end of the resetter and employing a mode of performing intramedullary imaging onthe thighbone by the ultrasonic probe. Simultaneously, compared with a mode of imaging employing a C-arm machine, the intramedullary resetting device for the thighbone, provided by the embodiments ofthe invention, has the advantages that the timeliness is higher, and harm caused by irradiation is avoided. In addition, due to interference to images caused by various tissue in the bone, optical imaging of the C-arm machine is not prone to penetration, and ultrasonic signals can penetrate, so that the intramedullary resetting device for the thighbone is higher in identity.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a femoral intramedullary reset device. Background technique [0002] Femoral shaft fractures are common fractures, accounting for about 5% of systemic fractures. They are more common in young and middle-aged people, and are mostly caused by falls and falls from heights. Since the femoral shaft is the longest and strongest bone in the human body, it has extremely important functions for the walking, standing and labor productivity of the human body. Effective treatment of femoral shaft fractures has great significance for reducing the disability rate. [0003] There are many methods of surgical treatment of femoral shaft fractures. The location and type of fracture, degree of comminution of fracture, patient's age, social and economic needs of the patient can all affect the choice of treatment method. Among them, open reduction and internal fixation with plate The treatme...
