Minimally invasive skeletal external fixation device for correcting foot accelerator drop and talipes varus

Abstract

The invention discloses a minimally invasive skeletal external fixation device for correcting foot accelerator drop and talipes varus. The minimally invasive skeletal external fixation device consists of an anti-toe-bending frame, a metatarsus needle adjuster, a heel bone needle adjuster, a heel bone needle adjuster bracket, a metatarsus needle adjuster bracket, an arc-shaped frame, a distal end bone needle clamp, an adjusting nut, a movement bone needle clamp, a proximal end bone needle clamp, a guide rail, a distal end bone needle, a movement bone needle, a proximal end bone needle, a heel bone needle and a metatarsus bone needle, wherein the guide rail is an assembly of the minimally invasive skeletal external fixation device; the anti-toe-bending frame and the metatarsus needle adjuster are connected with the metatarsus needle adjuster bracket clamped on the guide rail; the heel bone needle adjuster is connected with the heel bone needle adjuster bracket clamped on the guide rail; the distal end bone needle clamp, the movement bone needle clamp and the proximal end bone needle clamp are inserted into the guide rail, and are used for clamping corresponding bone needles; and the arc-shaped frame is clamped on the guide rail. The minimally invasive skeletal external fixation device can be used for correcting foot accelerator drop and talipes varus, performing one-time treatment on a patient suffering from foot accelerator drop, talipes varus, talipes valgus, bone lengthening, bone movement and the like and treating a patient suffering from one disease.

Description

technical field [0001] The invention relates to the field of orthopedics. In particular, the invention relates to a minimally invasive external bone fixation device for the correction of the foot drop and the foot varus, which needs to be lengthened with the shortening of the tibia or needs to be moved with the bone defect. Background technique [0002] Due to trauma or unsatisfactory surgical treatment, foot drop or foot inversion or foot valgus may be caused; some may also cause scars and tendon atrophy; more serious ones may cause shin bone shortening, making the affected leg shorter than the other leg There is a bone defect in one part of the tibia or due to infection or other reasons. Some of these phenomena have only one pathological condition in the patient, and some may have several pathological conditions appearing on the same leg of the same patient at the same time. Seriously affect the quality of life of the patient, make it difficult for the patient to move, a...

Problems solved by technology

Seriously affect the quality of life of the patient, make it difficult for the patient to move, and even make the patient lose a certain ability to work

[0003] The cause of foot drop, foot inversion, and foot valgus is mostly due to the fact that the affected foot is in one posture for a long time during the treatment process, and the recovery is not ideal, which makes some tendons around the foot joints, such as the Achilles tendon, shorten; the scars are postoperative A common phenomenon is that some scars are stiff and atrophied; some patients recover from tibial surgery and the length of the other leg is shorter than the other leg, resulting in lameness of the patient. What is more serious is that the patient's bone is not connected after the operation or even infected due to improper handling, resulting in tibial fractures. Osteomyelitis, bone defect

[0004] At present, the Achilles tendon is mostly released for the treatment of foot drop, and the medial and lateral tendons are used for the inversion and eversion of the foot. The tendon atrophy of the scar type is also mostly released by surgery. These methods not only give The patient is financially stressed, mentally hit hard, causing a lot of pain, and it will also cause secondary scars or atrophy, or bone tissue defects in the tibia due to infection and other reasons. Bone grafting is often performed by removing infected bone and implanting bone tissue. After all, it is a foreign bone, and the bone graft often fails due to rejection

If foot drop, foot varus, foot valgus, tendon atrophy at the scar, tibial shortening, and tibial bone defect appear on the same leg of the same patient, the previous surgery is very complicated and often requires multiple procedures. This will cause a lot of economic loss to the patient, and it will take several years from surgery to recovery, and the effect is not ideal.
