Embodiment Construction

[0014] The present invention will now be further described in conjunction with the accompanying drawings and preferred embodiments. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0015] Such as figure 1 and figure 2 A combined clavicle intramedullary nail shown in the clavicle fracture operation is composed of an outer nail 1 with an inner hole 11 and an inner nail 2. One end of the outer nail 1 is a first outer threaded nail. The joint end 12, one end of the inner nail 2 is a second joint end 21 with external thread, which is used to respectively engage the broken clavicle, the pitch of the external thread of the first joint end 12 is greater than the pitch of the external thread of the second joint end 21, this embodiment Among them, the pitch of the external thread of the first joint end 12 is 0.8 mm, th...

Abstract

The invention discloses a combined type clavicular intramedullary pin for orthopedic surgery, which comprises an outer sleeve pin with an inner bore and an inner pin, wherein one end of the outer sleeve pin is provided with a first joint end having external threads, one end of the inner pin is provided with a second joint end with the external threads, the thread pitch of the external threads of the first joint end is larger than that of the second joint end, the inner pin penetrates through the inner bore of the outer sleeve pin to be connected with the inner wall threads of the first joint end of the outer sleeve pin, and the second joint end of the inner pin is extended out of the outer sleeve pin. The invention solves the problem that the fixation technique adopted by the existing clavicle fracture surgery can not produce compressive stress, realizes the firmly fixation of fractured bones, has simple operation, is safe and convenient, and can be taken out more conveniently.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a combined clavicular intramedullary nail for human clavicle surgery. Background technique [0002] Clavicle fracture is one of the common clinical fractures, and this type of fracture occurs mostly in the middle and outer 1 / 3 of the clavicle. When doctors operate on this type of fracture, at present, Kirschner wire and reconstruction plate internal fixation are mostly used for surgical treatment of this type of fracture. Slipping nails and broken needles occur; reconstruction plate internal fixation is relatively strong, but the operation is relatively complicated and difficult, and after fixation, more prominent skin protrusions and scars will be formed on the patient's body surface, especially in summer. Contents of the invention [0003] The technical problem to be solved by the present invention is: to overcome the deficiencies in the prior art, to provide a combi...
