Technical Field

The invention relates to the field of medical instruments, in particular to an anatomical sternoclavicular joint bone fracture plate and a sternoclavicular joint internal fixation system.

Background

The dislocation of the sternoclavicular joint fracture is a common clinical disease, sometimes causes serious consequences, such as dysphoria, hoarseness, pneumothorax, dyspnea, brachial plexus nerve injury and related symptoms in blood vessels, and long-term complications also include related symptoms of labored respiration, blood vessel compression and brachial plexus compression, and even lead to thoracic outlet syndrome, septicemia, even death and the like.

At present, internal fixation methods used for dislocation of the sternoclavicular joint comprise kirschner wire fixation and steel wire fixation, and because the sternum is cancellous bone and the clavicle is positioned on the front outer side of the sternoclavicular joint, the internal fixation method of the kirschner wire cannot effectively fix the sternum, and the internal fixation method is very difficult after operation, so that the dislocation is often generated again due to the infirm fixation. The kirschner wire moves into the thoracic cavity to cause more injuries, the external fixation time is long, the pain of a patient is great, and the influence on daily life is great. In the prior art, the clavicle hook steel plate for dislocation of the acromioclavicular joint has poor matching and poor stability, and does not accord with the physiological movement characteristics of the joint; the steel wire fixation is prone to fracture failure.

Detailed Description

The technical solution of the present invention is further illustrated by the following specific examples.

Referring to fig. 1 to 5, an anatomical sternoclavicular joint bone plate is provided in this embodiment, and includes a bone plate main body 1, where the bone plate main body 1 includes a proximal end and a distal end, the proximal end of the bone plate main body 1 is attached to a clavicle portion of a sternoclavicular joint, the proximal end of the bone plate main body 1 is provided with a movable hole 2, an inner wall of the movable hole 2 is a smooth surface, a gap exists between the inner wall of the movable hole 2 and a screw penetrating into the movable hole, a central axis of the movable hole 2 passes through the sternoclavicular joint, and the distal end of the bone plate main body 1 is provided with a plurality of locking holes 3.

Anatomical form sternoclavicular joint coaptation board is equipped with movable hole 2 at the near-end of osteotomy plate main part in this embodiment, has the clearance between movable hole 2 and the screw, consequently, has relative motion's space between screw and coaptation board main part 1, and after the operation, the fine motion can be realized between the sternoclavicular joint, can realize earlier the joint function, adopts coaptation board and screw to fix the sternoclavicular joint simultaneously, has good fixed effect, effectively guarantees the stability after the dislocation of sternoclavicular joint.

In the present embodiment, as shown in fig. 1, the movable hole 2 is an oblong hole and can move relative to the screw in the longitudinal direction of the movable hole 2. Wherein, the length direction of activity hole 2 is unanimous with the length direction of coaptation board main part 1, can accord with the fine motion law of sternoclavicular joint department, guarantees that the patient can accomplish early exercise, has earlier recovery joint function.

In the present embodiment, the screw engaged with the movable hole 2 is a cancellous screw 6.

Preferably, the linear section of the active orifice 2 is between 0.5mm and 2mm, for example 1mm or 1.5 mm.

In the embodiment, the locking holes 3 of the bone fracture plate are tapered thread locking holes 3, and the bone fracture plate and the clavicle can be firmly locked by using the locking nails. The locking holes 3 are multiple, and can be two, three or more, so as to ensure that the bone fracture plate is firmly fixed on the clavicle.

One side of the movable hole 2 close to the locking hole 3 is provided with a composite hole 4, the composite hole 4 is a combination hole of the locking hole 3 and a pressurizing hole, and one side of the pressurizing hole can prevent a skin nail from being used for temporarily fixing the bone fracture plate; locking screws can be placed in the locking holes 3 to fix the bone plate.
