Anatomical biomechanical type 3D printing humerus greater tubercle cleavage fracture guider

Abstract

The invention belongs to the technical field of medical equipment, and particularly discloses an anatomical biomechanical type 3D printing humerus greater tubercle cleavage fracture guider which comprises a guide plate, a first protrusion, a second protrusion, a third protrusion, a fourth protrusion and a fifth protrusion are arranged on the guide plate in the circumferential direction, and a biomechanical guide sleeve part is detachably connected to the outer side of the guide plate. The biomechanical guide sleeve part comprises a clamping plate detachably connected with the guide plate, a plurality of guide sleeves are arranged on the side, away from the guide plate, of the clamping plate, and a plurality of first through holes communicated with the guide sleeves are formed in the clamping plate; a plurality of second through holes communicated with the first through holes are formed in the guide plate; and the fixing part is used for fixing the positions of the guide plate and the biomechanical guide sleeve part. The scheme is mainly applied to reduction and fixation treatment of the greater tuberosity cleavage fracture of the humerus, and the problems that an existing hollow screw is poor in fixation biomechanics and the like are solved.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and specifically discloses an anatomical and biomechanical 3D printed humerus greater tuberosity split fracture guide. Background technique [0002] Proximal humerus fractures, distal radius fractures, and hip fractures are also called the three most common fractures in the elderly, while the greater tuberosity fractures account for 15-20% of proximal humerus fractures, and are also a common problem that plagues the health of the elderly. disease. The greater tuberosity fracture of the humerus is not only a series of trauma diseases, it is related to the rotator cuff injury disease in the field of shoulder sports medicine, and it is also a disease frequently affected by comminuted fractures of the proximal humerus. [0003] For fractures of the greater tuberosity of the humerus, there are currently three main types of surgical procedures in the world: cannulated screws, plates, and sut...

AI Technical Summary

Problems solved by technology

[0003] For fractures of the greater tuberosity of the humerus, there are currently three major types of surgical procedures in the global clinic: cannulated screws, plates, and suture anchors. However, there is no unified gold standard for surgical methods.

Although the hollow screw is simple, practical and cheap, it also has many defects. First, for the elderly with osteoporosis, its fixation biomechanics is not strong, and it is easy to fail; second, the fixation angle is single. Since the hollow screw, the domestic The vertical fixation (90°) has always been used outside, and the fixation of the strong process needs to be improved; third, the vertical fixation is under the cartilage, and there are a series of complications after the cartilage is worn through and enters the articular surface; After reduction, there is also a lack of specialized guiding tools; fifth, there is currently no reduction or treatment tool that takes full advantage of the anatomical characteristics of the greater tubercle, and the current treatment ideas and concepts are still relatively old and not innovative
