Technical Field

[0001] The invention belongs to the technical field of medical instruments, and more specifically, particularly relates to a tension measuring device for the collateral ligament of a knee joint. Background Art

[0002] When people do strenuous exercise, their knee joints may be injured. After the injury, the collateral ligaments on both sides of the joint will be torn, resulting in a decrease in the tension of the collateral ligaments. As the injury worsens, the decrease in tension becomes more obvious. During treatment, it is necessary to accurately confirm the degree of tearing of the patient's collateral ligaments in order to perform the corresponding surgery.

[0003] Based on the above, the inventors have found the following problems: Currently, when diagnosing a patient's condition, due to the lack of dedicated medical instruments to accurately measure the tension of the collateral ligament of the knee joint, doctors can only press the corresponding parts by hand to estimate whether the tear of the patient's collateral ligament is mild, moderate or severe, and then arrange surgery. However, this method cannot determine the specific extent of the patient's injury, and cannot accurately judge the condition. At the same time, if the doctor applies too much force, it may cause secondary damage to the patient.
