Abstract

The present invention relates to the field of orthopedics, in particular to an orthopedic drilling guide and aiming device, which includes a supporting mounting plate, and further includes: two sets of rotating clamping mechanisms; and the two sets of rotating clamping mechanisms are respectively arranged at both ends of the supporting mounting plate; The supporting mounting plate is provided with a moving displacement mechanism in conjunction with the rotating clamping mechanism at one end, and the rotating clamping mechanism is provided with a displacement drilling mechanism; the supporting mounting plate is provided with a guide lifting The mechanism, through two sets of rotating clamping mechanisms, realizes the elastic fixation of the patient's joints, and cooperates with the guide movement to adjust the clamping distance between the two, and adjusts the elevation angle between the two through lifting, so that the device can adapt to different patients At the same time, it can also adapt to the clamping needs of different parts. In combination with the swing, guide displacement, and rotation telescopic adjustment of the displacement drilling mechanism, the device can adapt to the multi-angle drilling requirements and significantly improve the drilling efficiency. precision and efficiency.

Description

technical field [0001] The invention relates to the field of orthopedics, in particular to an orthopedic drilling guide aiming device. Background technique [0002] Orthopedics is also known as orthopedics. Is a profession or discipline of medicine, specializing in the study of the anatomy, physiology and pathology of the musculoskeletal system, the use of drugs, surgery and physical methods to maintain and develop the normal form and function of this system, and the treatment of injuries and diseases of this system; drilling; Surgery and needle fixation refer to the avascular necrosis of a part of the articular subchondral bone, and the articular cartilage overlying it degenerates. With further development, the necrotic bone and cartilage gradually separate from the adjacent bone and cartilage to form fragments. Falling off as loose bodies, the disease is most common in the knee joint, followed by the elbow, ankle, shoulder, and hip joint. [0003] Although the currently ...
