Problems solved by technology

[0004] However, in the above method, after the patient’s fibula is amputated, there is no suitable connecting member to restrict and connect the amputated fibula; if the conventional rigid plate connection widely used in orthopedics is used, the amputated fibula will be rigidly fused again Therefore, during the rehabilitation process after amputation of the fibula, the fibula in the patient's leg is pulled by the muscles to swing and move, or the bone tissue at the amputated end of the fibula is allowed to grow freely, without any delay. Unlimited; because of this, patients cannot obtain stable and good expected recovery

Embodiment Construction

[0046] see Figure 1-19 As shown, the present invention relates to a joint device for preventing bone fusion at the cut-off part of the fibula, including: a first connecting part 11 for connecting the first truncated end F1 of the cut-off part of the fibula F; a second connecting part 12 , used to connect the second truncated end F2 of the truncation of the fibula F; and an elastic part 13 connected between the first and second engaging parts 11 and 12 and subjected to the action of the first and second engaging parts 11 and 12 Force and elastic deformation; in this way, the present invention can be connected to the first and second truncated ends F1, F2 of the truncated fibula F, and the elastic part 13 of the present invention can deform with the characteristics of external force, so that the connected fibula F is not rigid Bones, eliminate the supporting force on the outer side of the tibia T, ensure that the tibial plateau is evenly subsided, and eliminate the sore lesions...

Abstract

The invention discloses an engagement device for preventing bone fusion of a fibula truncation part. The engagement device comprises a first engagement part, a second engagement part and an elastic part, wherein the first engagement part is used for engaging a first truncation end of a truncated fibula positioned at the outer side of a shin bone; the second engagement part is used for engaging a second truncation end of the fibula; the elastic part is engaged between the first and second engagement parts, so that the elastic part can be subjected to elastic deformation due to the acting force between the first and second engagement parts; and if the engagement device is engaged at two ends of the fibula truncation part, rigid re-fusion of the truncated fibula can be effectively prevented so as to remove the supporting force at the outer side of the shin bone of a patient, so that a shin bone platform can be settled uniformly.

Description

technical field [0001] The invention relates to a joint device for preventing bone fusion at the severed fibula, especially a device for connecting the two ends of the severed fibula, which can be deformed with external force, so as to effectively prevent the severed fibula from being rigidly fused again and reduce the risk of fracture. In addition to the supporting force on the lateral side of the tibia, and restrain the articulation device of the severed fibula. Background technique [0002] Knee joint lesions are mostly caused by trauma, degeneration, or osteoporosis; at present, for the treatment of knee joint lesions, most of them use the method of replacing the artificial joint to relieve the patient's focus, but due to the replacement of the artificial joint, surgery must be performed. To remove most of the patient's bone, the patient must cut a large wound, making this type of operation have the disadvantages of greater risk and slower recovery. [0003] Recently, t...
