Embodiment 1

[0038] Such as figure 1 with figure 2 As shown, a fibular transverse bone transport external fixator device includes a fibula transport device, a tibial fixation device and a connecting device, and the fibula transport device and the tibial fixation device are connected through the connecting device.

[0039] In this embodiment, the fibula handling device includes a fixed seat 6 arranged on the connecting device, a fibula transport frame movably mounted on the fixed seat 6, and a fixed seat 6 for adjusting the fibula transport frame relative to the fixed seat 6. Adjusting device for movement.

[0040] In this embodiment, the fibula transport frame includes an adjustment screw 9 vertically penetrating through the fixing seat 6, a moving block 7 fixedly connected to the adjustment screw 9, and a fibula fixing rod arranged on the moving block 7;

[0041] The adjusting device in this embodiment includes an adjusting nut 8 , which runs through the adjusting screw 9 and is movabl...

Embodiment 2

[0051] This embodiment is similar to Embodiment 1, and the difference is that in this embodiment, the diameter of the fibula fixation bone pin 4 is 1.7 mm, the diameter of the tibia fixation bone pin 3 is 3.0 mm, and the central angle of the arc-shaped round rod 1 is 7°. °, the structure and working principle of other parts of this embodiment are the same as those of Embodiment 1.

Embodiment 3

[0053] This embodiment is similar to Embodiment 1, and the difference is that in this embodiment, the diameter of the fibula fixation bone pin 4 is 2.5 mm, the diameter of the tibial bone fixation bone pin 3 is 3.5 mm, and the central angle of the arc-shaped round rod 1 is 95 mm. °, the structure and working principle of other parts of this embodiment are the same as those of Embodiment 1.

Abstract

The invention provides a fibula transverse bone carrying external fixing frame device which comprises a fibula carrying device, a tibia fixing device and a connecting device, the fibula carrying device drives a fibula carrying frame to move synchronously through movement of an adjusting device, position deviation of bone blocks of a fibula osteotomy section is achieved, the tibia fixing device comprises a tibia fixing frame and a deviation rectifying adjusting device, the deviation rectifying adjusting device can adjust the fixing positions of the tibia fixing frame and the connecting device, and the fibula carrying device and the tibia fixing device are connected through the connecting device. The invention further provides a using method of the fibula transverse bone carrying external fixing frame device. Only the fixing fulcrum is arranged on the tibia; the number of wounds on the tibia side is reduced; the bearing capacity of the tibia after operation is not affected, meanwhile; bone carrying operation is conducted on the fibula side; transverse fibula carrying is achieved; the fibula is located in the deep layer of skin fascia; muscle groups in front of and behind the fibula are wrapped; and a richer capillary basis is provided for bone carrying at the fibula end; and the blood supply repairing effect is better.

Description

technical field [0001] The invention relates to the technical field of medical orthopedic instruments, and more particularly, to a fibula transverse bone transport external fixator device and a method for using the same. Background technique [0002] Diabetic foot has the characteristics of poor local blood supply, low immune function, and easy infection and spread. Therefore, the wound healing of diabetic foot is slow and often protracted. The etiology of diabetic foot is mainly the combined effect of microangiopathy and peripheral nerve entrapment. With the aging population, the incidence of diabetic foot is increasing, and the non-healing rate of wounds is also increasing; due to the lack of effective treatment, this will develop into a serious social problem. Based on the current status of diabetic foot treatment, debridement and removal of necrotic tissue, triple neurolysis, stem cell transplantation, lower extremity vascular bypass surgery, and tibial lateral transfer...
