Abstract
Description
Technical Field
[0001] The utility model relates to an orthopedic tool, in particular to a universal bone resetting device. Background Art
[0002] Reduction devices are widely used in orthopedic spinal surgery and long bone fracture reduction. Their precise angle adjustment and fixation capabilities enable medical staff to more effectively perform reduction procedures, alleviating pain and the burden of recovery for patients. Furthermore, the use of these devices helps improve surgical success rates and patient satisfaction, driving the continuous advancement and development of medical technology.
[0003] The specific functions of the bone reduction device during surgery are as follows:
[0004] 1. Reduction function: Bone reduction devices can directly restore fractured or dislocated bones to their normal anatomical position through external force, pressure, traction, etc. This is crucial for restoring the normal structure and function of bones.
[0005] Modern orthopedic reducers, such as digital reducers, can monitor the force and angle of the fracture site in real time through sensors and computer control, and provide feedback information to achieve precise reduction operations.
[0006] 2. Fixation
[0007] After the reduction is completed, the bone reduction device can also provide stable fixation to prevent the fracture site from displacing again and ensure that the bone heals in the correct position.
[0008] By immobilizing the fracture, bone reduction devices aid in the healing process at the fracture site and reduce the risk of delayed healing or malunion due to activity.
[0009] 3. Alleviate patients’ pain
[0010] Timely reduction and fixation can relieve the patient's pain and improve the patient's comfort.
[0011] Stable fixation helps reduce inflammation and swelling at the fracture site, thereby speeding up the patient's recovery process.
[0012] 4. Improve surgical efficiency and success rate
[0013] Modern orthopedic reducers are rationally designed and easy to operate, which can significantly reduce the difficulty and time of surgery.
[0014] Therefore, during surgery, in addition to paying attention to the control of reduction angle and force to avoid unnecessary harm to the patient, precise reduction and stable fixation can help improve the success rate of the surgery and reduce the occurrence of postoperative complications.
