The invention discloses a Taylor spatial frame for bone external fixing for pelvic fracture reduction. The Taylor spatial frame comprises six support rods, a fixing block, driving apparatus, and a motor fixing box, wherein each support rod comprises a sleeve and a connecting rod which are connected in a threaded manner, and a first gear coaxially and fixedly arranged on the sleeve, the top ends ofthe sleeves are hinged with a full ring located above in a universal manner, the bottom ends of the connecting rods are hinged with a full ring located below in a universal manner, the fixing block is detachably and fixedly connected with one of the connecting rods, and is provided with a threaded hole parallel to the connecting rod in a penetrating manner, the driving apparatus comprises a threaded rod screwed with the threaded hole, a second gear coaxially and fixedly arranged on the threaded rod and meshed with the corresponding first gear, and a driving motor fixedly arranged on the bottom of the threaded rod, the motor fixing box is detachably connected with the corresponding connecting rod in a slide manner, and the driving motor is fixedly connected in the motor fixing box. According to the Taylor spatial frame, the driving apparatus is detachably installed on the support rods, the weight of the support rods is reduced, and at the same time, the manufacturing cost of the Taylorspatial frame is reduced.
Description
technical field [0001] The invention relates to the field of medical devices, in particular to a Taylor space external bone fixation bracket for pelvic fracture reduction. Background technique [0002] The pelvic cavity is full of important organs and important blood vessels and nerves that control the lower limbs, and the important nerves and blood vessels of the pelvis are mostly concentrated near the posterior pelvic ring. Once the posterior pelvic ring is damaged, it will easily lead to death and disability of the patient. Fractures are mostly unstable pelvic fractures, and it has been reported in the literature that the fatal and disability rates of unstable pelvic fractures can be as high as 10-40%. Therefore, in order to minimize the incidence of complications of unstable pelvic fractures, accurate reduction and timely fixation are very important for the prognosis of patients with unstable pelvic fractures. Taylor space external fixation bracket (referred to as Taylo...
