Problems solved by technology

However, there are many disadvantages in the currently used bone plate at the distal end of the clavicle. For example, there is no Kirschner wire hole at the proximal end of the bone plate for positioning and temporary fixation, which causes the bone plate to easily shift during fixation; When locking, it is impossible to further adjust the fracture end and fine-tune the fracture end to better achieve anatomical reduction; there is no Kirschner wire hole in the middle of the bone plate, and it is impossible to fix small bone fragments

Embodiment 1

[0021] Such as Figure 1-Figure 3 A bone plate for the distal clavicle is shown, which includes a bone plate body 1. The bone plate body 1 is generally S-shaped, taking into account both sagittal and coronal S-shaped shapes and has a gradual change, conforming to the anatomical structure of the distal clavicle , the bone plate body 1 is divided into a distal acromioclavicular joint section 2, an intermediate section 3 and a proximal acromioclavicular joint section 4, the proximal acromioclavicular joint section 4 is a curved surface structure, and the distal acromioclavicular joint section 2 runs from left to The right side is provided with the far shoulder lock Kirschner wire hole 5, the far shoulder lock lock hole 6 and the sliding hole 7 successively. There are intermediate locking holes 8 and sliding holes I9 from left to right. There are multiple intermediate locking holes 8, and intermediate Kirschner wire holes 10 are opened between adjacent intermediate locking holes 8...

Embodiment 2

[0023] Such as Figure 1-Figure 3 A bone plate for the distal clavicle is shown, which includes a bone plate body 1. The bone plate body 1 is generally S-shaped, taking into account both sagittal and coronal S-shaped shapes and has a gradual change, conforming to the anatomical structure of the distal clavicle , the edge of the bone plate body 1 is a smooth arc surface structure, which can reduce tendon, ligament, soft tissue friction damage and foreign body sensation, the thickness of the bone plate body 1 is 2.0-3.1mm, the length is 5-20cm, and the width is 1mm. -1.8cm, the bone plate body 1 is divided into a distal acromioclavicular joint segment 2, an intermediate segment 3 and a proximal acromioclavicular joint segment 4, the proximal acromioclavicular joint segment 4 is a curved surface structure, and the design is relatively thin, which can reduce tendon, Frictional damage to ligaments and soft tissues, the average thickness of the middle section 3 and the distal acromi...

Abstract

The invention discloses a far-end clavicle bone fracture plate which comprises a bone fracture plate body, the bone fracture plate body is integrally in an S shape, takes the S shape of a sagittal plane and the S shape of a coronal plane into account, has gradual change, conforms to a distal clavicle anatomical structure and is divided into a distal acromioclavicular joint section, a middle section and a proximal acromioclavicular joint section, the distal acromioclavicular joint section is sequentially provided with a distal acromioclavicular kirschner wire hole, distal acromioclavicular locking holes and a sliding hole from left to right, the middle section is provided with a plurality of middle locking holes and a sliding hole I from left to right, a middle kirschner wire hole is formed between every two adjacent middle locking holes. A proximal acromioclavicular locking hole is formed in the proximal acromioclavicular joint section, and a plurality of proximal acromioclavicular kirschner wire holes is formed in the right end of the proximal acromioclavicular joint section along the periphery. The width and curvature are designed according to the distal clavicle anatomical structure, and the device is an anatomical locking plate and can be tightly attached to the bone surface without intraoperative shaping, so that the strength of the bone fracture plate cannot be reduced, and the operation time cannot be prolonged.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a bone plate at the distal end of the clavicle. Background technique [0002] Bones in various parts of the body may be fractured due to trauma or other reasons, and the injured bones need to be repaired in a timely and correct manner after the fracture. The locking plate is a bone fixation implant commonly used in surgical fracture operations. The existing reconstruction bone plate is poor in plasticity, so that the bone plate cannot fix the bone firmly, resulting in torsion of the bone and other phenomena, resulting in an increase in the healing period of the patient, so anatomical locking bone plates are often used. Clavicle fracture is one of the common fractures in the human body. It can occur in the proximal, distal and middle sections of the clavicle, and can occur in all age groups. It is manifested by pain, swelling, and limited shoulder joint movement at the fr...
