Problems solved by technology

[0007] The use of the clavicular hook bone plate is to preserve the "micro-movement" function of the local facet joints to the greatest extent, but the problem is that when the hook is implanted to the rear of the sternum, there is a possibility ...

Embodiment Construction

[0022] In order to make the technical problems, technical solutions and advantages to be solved by the embodiments of the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0023] Such as figure 1 and figure 2 As shown, the present invention provides a hinged bone plate for dislocation of the sternoclavicular joint, comprising a clavicle part 1 of the bone plate fitted to the clavicular part of a human body and a thoracic part 2 of the bone plate fitted to the thoracic part of the human body; The clavicular part of the bone plate and the thoracic part of the bone plate are flexibly buckled at one end; the fastening is realized by the following method: a mortise structure is arranged at one end of the clavicle part of the bone plate, and a mortise structure is arranged at one end of the thoracic part of the bone plate to connect with the thoracic part of the bone plate. The mortise structure is a solid h...

Abstract

The invention discloses a hinge type bone fracture plate used for dislocation of a sternoclavicular joint. The hinge type bone fracture plate comprises a bone fracture plate clavicle part fitting a clavicle part of a human body and a bone fracture plate thoracoacromial part fitting a thoracoacromial part of the human body; the bone fracture plate clavicle part and the bone fracture plate thoracoacromial part are movably fastened at one end, a plurality of fixing holes are formed in each of the surfaces of the bone fracture plate clavicle part and the bone fracture plate thoracoacromial part, each fixing hole is fixed through a fixing screw, the fixing screw comprises a hollow screw and a central bolt, and the hollow screw is expanded open to realize fixation after the central bolt is screwed into the hollow screw. The hinge type bone fracture plate used for dislocation of the sternoclavicular joint keeps the micro motion of the sternoclavicular joint between the far end of the clavicle and the thoracoacromial, and the joint function of the part is simulated to the greatest extent, so that the motion of the sternoclavicular joint of a patient rapidly recovers to the normal level after the operation.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a hinged bone plate for sternoclavicular joint dislocation. Background technique [0002] At present, the treatment methods for sternoclavicular joint dislocation and proximal clavicle fracture generally include the following methods: [0003] (1) Directly connect the proximal segment of the clavicle and the sternum after shaping with the reconstruction bone plate; [0004] (2) Use Kirschner wires to fix the proximal clavicle and sternum; [0005] (3) It is also reported that the clavicle hook plate is used to insert the hook part behind the sternum to achieve "micro-motion" fixation like the sternoclavicular joint at the distal end of the clavicle. [0006] The above first and second internal fixation methods all have a common disadvantage of complete fixation, that is, the "micro-movement" function of the sternoclavicular joint between the proximal clavicle and the sternum is l...
